RESUMEN

This study aimed to evaluate the impact of thyme and/or garlic oil administration on growth performance, immunity, antioxidant, biochemical parameters, and net farm income of Damascus goats. Forty weaned Damascus goats were allocated into four groups. The first group was the control without oral administration, while the 2nd (Th), 3rd (Gr), and 4th (ThGr) groups were orally administrated by (2 ml/goat/day) of thyme oil, garlic oil and their mixture (1:1), respectively during the whole experiment period. The final body weight of goats orally administered oil mixture was the heaviest group, it was 10, 4.5 and 3.5% than the control, Th. and Gr. groups, respectively with better feed conversion ratio and high net farm income. Goats of ThGr. group revealed the best immunity, antioxidant and general health condition than the control group with 50% reduction of MDA. Liver (AST, 33% and ALT, 38%) and kidney (creatinine, 88%) functions improved by oils mixtures orally administration compared with the control group. LDL, triglyceride and cholesterol were reduced by 47, 33 and 21% compared with the control group, respectively. Thus, mixture oil administration (thyme and garlic at the ratio of 1:1, 2 ml/goat/day) improved growth (10%), antioxidant status (MDA 50%), liver (AST, 33% and ALT, 38%), kidney function (creatinine, 88%), the FCR (17.4%) and net farm income (21%), of Damascus goats.

RESUMEN

Puerarin is an isoflavone extracted from Pueraria mirifica, a wildlife leguminous plant. It has been reported to possess antioxidant, anti-inflammatory, and anti-bacterial properties. However, the effects of directly adding puerarin to the diets of sows, in terms of reproductive performance and antioxidant properties, have not been reported. For this study, 240 sows with varying parities were selected and randomly divided into six treatment groups using a two × three experimental design. The six treatment groups consisted of two diets (control and puerarin) and three parities (zero, one, and two parities or more). The puerarin group was supplemented with 1 g/kg of puerarin. The experiment commenced with mating and continued until 21 days post-delivery. The sow reproductive performance was not affected by supplementing their diets with puerarin (p > 0.05). Dietary supplementation with puerarin significantly increased the daily body weight (BW) gain of piglets and their mean BW at weaning (p < 0.05). Compared with the control group, sows in the puerarin group had significantly higher glutathione peroxidase activity in serum and also significantly increased immunoglobulin A and G levels in serum, colostrum, and milk, but significantly lower malondialdehyde concentration in serum (p < 0.05). Thus, puerarin improved the immune response and antioxidant capacity of sows and increased the daily BW gain of their offspring.

RESUMEN

This study employed a comprehensive approach to validate the hepatoprotective potential of phytoconstituents from Cichorium intybus leaves. In vitro, in vivo and in silico techniques were used to confirm the protective effects on liver enzymes. In vitro antioxidant assessment revealed the highest potential in the hydroethanolic leaf extract compared to aqueous and methanolic extracts. The study further investigated the ameliorative efficacy of the hydro-ethanolic extract (HECL) in male Wistar rats exposed to lead (50 mg/kg b wt.) and nickel (4.0 mg/kg b wt.) individually and in combination for 90 days. HECL at 250 mg/kg b wt. mitigated hepatic injury, oxidative stress, DNA fragmentation, ultrastructural and histopathological alterations induced by lead and nickel. Molecular docking explored the interaction of 28 phytoconstituents from C. intybus with hepatoprotective protein targets. Cyanidin and rutin exhibited the highest affinity for liver corrective enzymes among the screened phytoconstituents. These findings underscore the liver corrective potential of C. intybus leaf phytoconstituents, shedding light on their molecular interactions with hepatoprotective targets. This research contributes valuable insights into the therapeutic applications of C. intybus in liver protection.

RESUMEN

This study was conducted to investigate the effect of the duration of a flaxseed diet on fattening pigs' antioxidant defence mechanism in blood and tissues. Eighteen 20-week-old Landrace breed fattening pigs (BW 76.61 ± 2.30 kg) were divided into three groups of six animals. The control group was fed a basal diet. The FS3 group was fed the basal diet supplemented with 10% flaxseed for 3 weeks. The FS6 group received the same basal diet with flaxseed for 6 weeks. The total antioxidant capacity of the blood, measured as the total antioxidant status (TAS), total plasma antioxidant capacity (FRAP), reactive oxygen metabolites (dROMs) and total antioxidant capacity (PAT), was not affected by the flaxseed diet. The superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and glutathione reductase (GR) activities were significantly decreased in the FS3 pigs in the heart (p < 0.05). However, in the FS3 group, the glutathione-S-transferase (GST) activity significantly increased compared to the control, but in the FS6 group, the activity was inhibited (p < 0.05). In the muscle, the CAT and GST activity was significantly decreased in the FS3 group (p < 0.05). The thiobarbituric acid reactive substance (TBARS) content was significantly reduced in the brain, muscle and heart in the FS3 group(p < 0.05). In FS6, the TBARS content significantly increased in the heart and brain (p < 0.05). Our results showed that the health effect of a flaxseed diet is significantly conditioned by the length of the flaxseed addition.

RESUMEN

Thyme has strong antioxidant properties and, therefore, can reduce the intensity of oxidative processes taking place in the body. The study aimed to assess whether the addition of thyme to diets for fattening pigs containing extruded flaxseeds, a source of n-3 PUFAs, which are particularly susceptible to oxidation, would have a positive effect on redox status and lipid metabolism. The experiment was conducted using 120 weaners (WBP × Neckar crosses) of about 30 kg BW, which were kept until the end of fattening (about 110 kg BW) and divided into three groups of 40 pigs. The control group received a diet with 4% extruded flaxseed. In groups T1 and T3, 1% or 3% of thyme was added to the basal diet. The introduction of 3% thyme resulted in a decrease in the total cholesterol level in the blood and the loin muscle. Moreover, an increase in SOD and CAT activity and a decrease in FRAP and LOOH was noted. Following supplementation with 3% thyme, the n-3 PUFA content and n-3/n-6 ratio increased, while the SFA content was significantly reduced. The results of the studies indicate that thyme has a positive effect on the redox status and lipid profile of the blood and muscles.

RESUMEN

Medicinal plants are an important source of bioactive compounds with a wide spectrum of practically useful properties. Various types of antioxidants synthesized in plants are the reasons for their application in medicine, phytotherapy, and aromatherapy. Therefore, reliable, simple, cost-effective, eco-friendly, and rapid methods for the evaluation of antioxidant properties of medicinal plants and products on their basis are required. Electrochemical methods based on electron transfer reactions are promising tools to solve this problem. Total antioxidant parameters and individual antioxidant quantification can be achieved using suitable electrochemical techniques. The analytical capabilities of constant-current coulometry, potentiometry, various types of voltammetry, and chrono methods in the evaluation of total antioxidant parameters of medicinal plants and plant-derived products are presented. The advantages and limitations of methods in comparison to each other and traditional spectroscopic methods are discussed. The possibility to use electrochemical detection of the antioxidants via reactions with oxidants or radicals (N- and O-centered) in solution, with stable radicals immobilized on the electrode surface, via oxidation of antioxidants on a suitable electrode, allows the study of various mechanisms of antioxidant actions occurring in living systems. Attention is also paid to the individual or simultaneous electrochemical determination of antioxidants in medicinal plants using chemically modified electrodes.

RESUMEN

This study aimed to investigate the effects of Marigold flower powder (MFP) and marigold flower extract (MFEx) as feed additives on the performance, blood parameters, antioxidant capacity, immunological parameters, microbial content, digestive enzymes and digestibility in growing Japanese quail. A total number of 350 birds randomly distributed into seven groups, with five replicates of 10 birds each, control diet (control group), the second, third and fourth groups were fed on a basal diet within MFP 0.6%, 0.9% and 1.2% respectively. Fifth, sixth and seventh groups received the basal diet plus MFEx 150, 200 and 250 ppm respectively. Quails fed on a diet supplemented with MFEx 200 ppm had significantly higher lipase levels (p ≤ 0.001) compared to the control and MFP 0.6% without any significant difference with other experimental groups. Moreover, all digestibility coefficients (DC) of nutrients except for nitrogen-free extract were significantly (p ≤ 0.001) affected by all dietary treatments. Quails fed on the diet supplemented with MFEx 200 ppm significantly (p ≤ 0.001) presented the best body weight, body weight gain, feed conversion ratio and the lowest feed intake over all groups. Total lipid profile, kidney functions and liver functions were significantly affected by both MFP and MFEx diets. The group treated with MFEx 250 ppm had lowest E. coli and Salmonella population and the highest Lactobacilli population number. Antioxidant parameters and immune response (except for lymphocytes) were significantly affected (p ≤ 0.001) by different levels of MFP and MFEx. In conclusion, the addition of MFEx and MFP at 200 ppm followed by 250 ppm and 1.2% MFP, respectively, to the basal diet improved product productive performance, blood parameters, antioxidant capacity, immunological parameters, microbial content and digestibility in growing Japanese quail.

RESUMEN

Soil contamination with crude oil is a major environmental problem. The aim of this study was to assess whether the earthworm Allolobophora caliginosa could improve the degradation of petroleum hydrocarbons while enriching soils that were contaminated with crude oil. In addition, the toxic effects of crude oil on earthworms during bioremediation will be assessed. The soil samples were experimentally contaminated with two different quantities of light crude oil 5 or 7.5 ml for 60 days. Activities of A. caliginosa resulted in 33.56% and 54.98% total petroleum hydrocarbon (TPH) losses from the soil contaminated with 5 ml of crude oil after 22 and 60 days; respectively. While in 7.5 ml crude oil-contaminated soil, there was a loss of 32.24% and 71.05% of TPH over the same period of time. During the experiment, however, there were no signs of improvement in soil physicochemical properties. Earthworm tissue analyses at the end of the experiment showed significant bioaccumulation of petroleum hydrocarbons in their tissues and changes in their metabolic and hematological parameters. Earthworms exposed to crude oil showed a significant increase in protein, malondialdehyde, and glutathione but decreased in catalase levels and total antioxidant capacity compared to control earthworm after 60 days of exposure. There was a significant decrease in the Hgb, RBCS, Hct, MCV, MCH, platelet count, and WBCs. As a result, the earthworm Allolobophora caliginosa has been shown to be good bioremediator for oil-contaminated soils and also has potential as a bioindicator for contamination.

RESUMEN

Chemotherapy is the main approach for the treatment of cancer; however, it often causes unpleasant oxidative damages. Therefore, the development of an effective alternative/complementary therapy with improved tumor suppression efficiency and lower adverse effects is highly required. Recently, it has been shown that Cyrtopodion scabrum extract (CsE) is an effective and selective tumor suppressor medicine. The present study investigated the antioxidant activity of Cyrtopodion scabrum homogenate (CsH) and CsE and their effects on attenuating 5-fluorouracil (5-FU)-induced liver dysfunction in rats. A total of 60 male rats (weight: 200-220 g) were divided into six groups and treated for 14 days. The control (group I) and 5-FU (group II) groups received distilled water and 5-FU, respectively. The other four groups were orally administered with CsE, CsH, CsE+5-FU, and CsH+5-FU (groups III to VI), respectively by gavages based on a daily schedule. The 5-FU-induced oxidative damage was evaluated by changes in the weight and food and water intake during the treatment and antioxidant parameters in the liver and serum of the treated rats. The obtained data indicated that the administration of CsH and CsE significantly improved liver function and defense system of antioxidants by attenuating the levels or activities of malondialdehyde, superoxide anion, aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase and decrease of superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, glutathione S-transferase, total antioxidant capacity, glutathione, total protein, and albumin in the liver and serum, induced by 5-FU treatment. The obtained data of the current study suggested that CsH and CsE play a protective role in the imbalance elicited by 5-FU and can be used as alternative/complementary supplements with 5-FU to reduce oxidative damages which is the consequence of reactive oxygen species production in cancerous patients.

RESUMEN

BACKGROUND AND AIM: Postpartum uterine infectious diseases, such as pyometra, have discrepancy with both health and, subsequently, productivity of dairy cows due to its high prevalence and the high cost of treatment. Therefore, this study investigates the influence of pyometra on the reproductive indices, the metabolic profile, and oxidant/antioxidant parameters of the pyometric animal compared to those of healthy ones. MATERIALS AND METHODS: The study included 30 cows. The animals were differentiated into two groups of 15 cows each: A group of pyometra and a control group. All pyometric cows were subjected to breeding soundness examination after the end of pyometra and were compared to the control group. Blood samples were obtained to assess the levels of glucose, non-esterified fatty acids (NEFA), triglycerides (TGs), cholesterol, albumin, total protein, alanine aminotransferase, aspartate aminotransferase (AST), alkaline phosphatase (ALP), blood urea nitrogen (BUN), creatinine, calcium (Ca), phosphorus, sodium, potassium, progesterone hormone (P4), malondialdehyde (MDA), total antioxidant capacity (TAC), glutathione peroxidase (GPx), and superoxide dismutase. RESULTS: Results revealed significant prolonged duration of first estrus, the days open, and the required number of services due to pyometra. The pyometra group yielded increased levels of NEFA, TGs, ALP, BUN, creatinine, MDA, and progesterone hormone. In addition, significant decrease in the levels of glucose, cholesterol, albumin, Ca, phosphorus, sodium, TAC, GPx, and superoxide dismutase was observed in the pyometra group. Finally, no difference in the concentrations of total protein, ALT, AST, and potassium was observed in the pyometra group. CONCLUSION: The reproductive indices was adversely influenced in cows with postpartum pyometra, and metabolic profile, involving energy balance signals and liver function indicators, revealed differences between the two groups. Increased levels of oxidative stress parameters and decrease levels of antioxidant levels were also found, suggesting that pyometra is an incentive for oxidative stress. Overall, checking the energy balance, metabolic imbalances, and oxidant/antioxidant profile, accompanied with pre-emptive procedures during the postpartum period, is essential and can reduce the chances of such diseases and possible noxious results in highly productive cows.

RESUMEN

This study evaluated the effect of Artemisia absinthium and Malva sylvestris on antioxidant response and histopathological changes in the abomasa of the Haemonchus contortus infected lambs. Twenty-four lambs were divided into four groups: unsupplemented lambs (UNS), lambs supplemented with A. absinthium (ART), lambs supplemented with M. sylvestris (MAL), and lambs supplemented with both plants (ARTMAL). Lambs were infected orally with approximately 5000 third-stage (L3) larvae of H. contortus. The experiment was conducted for 75 d (days), all animals were then slaughtered; and the abomasal tissues were examined for antioxidant parameters and histopathology. The concentration of malondialdehyde in the abomasal mucosa was lower in ARTMAL (p < 0.05), and the total antioxidant capacity was higher in MAL (p < 0.05), than in UNS. Increased mucus production was observed in the ARTMAL. The number of mast cells in UNS and ART was significantly higher than the number in MAL (p < 0.01 and p < 0.05). Plasma cell numbers were higher in ARTMAL than the number in MAL (p < 0.05). Abomasal tissue regenerated more frequently in ARTMAL. These results represent the first report of the impact of A. absinthium and M. sylvestris on antioxidant parameters and local immune responses of abomasal mucosa of lambs infected with a GIN parasite.

RESUMEN

INTRODUCTION: Oxidative stress has been implicated in the pathogenesis of thyroid-associated orbitopathy (TAO) in patients with Graves' disease (GD). This study assessed the effect of thyroid hormone abnormalities on selected antioxidant parameters in patients with active TAO. MATERIAL AND METHODS: The study group consisted of 56 patients with GD and active TAO treated with antithyroid medication. Depending on the thyroid hormone level, they were subdivided into two groups: Group 1 - hyperthyroid patients (n = 34) and Group 2 - euthyroid patients (n = 22). The total oxidant status expressed as the ferric reducing ability of plasma (FRAP) as well as selected enzymatic and nonenzymatic components of the antioxidant system, including the activity of superoxide dismutase (SOD), glutathione peroxidase (GPx), and paraoxonase 1 (PON-1), as well as the levels of vitamin C, uric acid, and lipid peroxidation products: malondialdehyde (MDA) and conjugated dienes (CD) were assessed in all enrolled participants. RESULTS: The FRAP values in Group 1 were significantly higher than in controls. The FRAP values in Group 2 were lower than in Group 1 and higher than in controls. However, the differences were not significant. In Group 1, the activity of SOD and GPx, as well as serum levels of uric acid, MDA, and CD, were significantly higher than in controls. At the same time, serum PON-1 activity and vitamin C levels were significantly lower in Group 1 than in controls. In Group 2, the SOD activity as well as MDA and CD levels were non-significantly lower than in Group 1 and non-significantly higher than in controls. The activity of GPx in euthyroid patients with TAO was significantly higher than in controls. CONCLUSIONS: Hyperthyroidism is a significant contributor to oxidative stress in patients with active TAO, which manifests as upregulated lipid peroxidation and antioxidant system activation. Euthyroid state restoration leads to a relative reduction in activity and levels of most studied antioxidant parameters, which still remain above the normal values. The autoimmune inflammation of the orbital tissue seems to be a thyroid hormone status-independent modifier of oxidative stress.

RESUMEN

The amount of technological products including television, radio transmitters, and mobile phone that have entered our daily life has increased in recent years. But these devices may cause adverse effects on human health. Electromagnetic shielding fabrics may limit and inhibit electromagnetic waves. Aim of our study was to evaluate electromagnetic wave blocking performance of nonwoven textile surfaces on zebrafish embryos that were exposed to electromagnetic waves at specific frequencies. Oxidant-antioxidant system parameters were evaluated spectrophotometrically. The expressions of tp53 and casp3a were evaluated by RT-PCR. Results showed that electromagnetic shielding fabrics produced as conductive nonwoven textile surfaces improved oxidant-antioxidant status and tp53 expression that were impaired in electromagnetic waves exposed zebrafish embryos. Also, electromagnetic shielding fabrics decreased casp3a expression responsible for the execution phase of apoptosis that increased in electromagnetic waves exposed zebrafish embryos.

RESUMEN

OBJECTIVES: Natural medicine has been proposed for treating sepsis worldwide. Therefore, in this study, the effect of deuterium-depleted water (DDW) alone and adjuvant with Rosa damascena Mill. (RD) essential oils was considered through the evaluation of oxidative stress-antioxidant parameters and the expression of cyclooxygenase-2 (COX-2) inflammatory gene in liver damage caused by sepsis. MATERIALS AND METHODS: The rats were randomly divided into 5 groups: 1) laparotomy group; 2) cecal ligation and puncture (CLP) group; 3) DDW (15 ppm and 30 ppm doses) group; 4) DDW (15 ppm and 30 ppm doses) plus RD essential oil (100 mg/kg.bw); 5) indomethacin (2 mg/kg.bw) as a positive control. The treatments were daily administrated for 2 weeks and the CLP model was created on the day 15. Then, the animals were killed and their liver tissue was separated for histopathologic and biochemical assessment. RESULTS: Our results demonstrated that the treatment of animals with DDW and DDW plus RD essential oil was effective due to the regulation of the oxidative stress-antioxidant parameters including lipid peroxidation, glutathione (GSH), GSH s-transferases, myeloperoxidase, ferric reducing ability of plasma and inflammatory parameters such as prostaglandin E2 and COX-2. Pathological studies also showed that sepsis led to the liver tissue injuries, which can be reduced by treatments. CONCLUSION: Sepsis caused oxidative stress in the liver tissue, but the administration of DDW and DDW plus RD essential oil can be useful to prevent and heal these injuries.

RESUMEN

Doxorubicin (DOXO), a potent and widely used chemotherapeutic agent, causes irreversible heart failure by increasing oxidative stress, which limits its clinical utility. Nuclear factor erythroid-derived 2 -like 2 (Nrf2) is a prominent central regulator of cellular impenetrable to oxidants. The purpose of the study is to assess the ameliorative outcome of quercetin in cardiomyopathic rats induced by doxorubicin. Cardiomyopathy was produced in rats by single intraperitoneal weekly with DOXO (2 mg/kg) for 4 weeks. The rats were divided into five groups: (I) control group; (II) DOXO (2 mg/kg, i.p.) group; (III-V) DOXO + quercetin (10 mg/kg, 25 mg/kg and 50 mg/kg, orally), and were treated for 7 weeks. At the end of the treatment duration, cardiac function and biochemical parameters were assessed. Quercetin (10 mg/kg, 25 mg/kg and 50 mg/kg, orally) treatment reduced the raised blood pressure (BP) and left ventricular dysfunction. Withal, it prevented the rise in CKMB and LDH, suggesting the effect of quercetin in the maintaining the integrity of the cell membrane Besides, it also prevented the alteration in electrolyte levels, the activity of ATPase, and antioxidant status. Quercetin increased Nrf2 mRNA expression and reduced histological abnormalities compared to the DOXO control group. In conclusion, quercetin protected against DOXO- induced cardiomyopathy, by increasing expression of NRF2, and thereby increasing antioxidant defense and restoring biochemical and histological abnormalities.

RESUMEN

The aim of the study was to analyze the influence of diet containing the polyphenol-rich material on intestinal enzyme activity, oxidative stress markers, lipid metabolism and antioxidant status of laboratory rats. The animals were fed high-fat diet supplemented with freeze-dried water extracts of raw and roasted cocoa beans of Forastero variety. The observed changes indicated the biological activity of polyphenols and other components of the prepared cocoa beans extracts (CBEs). The presence of raw and roasted CBEs in the diets diversified the activity of the enzymes of the cecal microflora of rats. Both CBEs beneficially affect the antioxidant status of the serum, even in relation to the control standard group. The experimental cocoa bean preparations showed no significant effect on the mass of rats' liver, heart, and kidneys, but varied some parameters of the antioxidant status of their organisms. The raw CBE in rats fed with the high-fat diet shows a high ability to inhibit lipid peroxidation in heart and more effectively increases hepatic reduced glutathione (GSH) concentrations compared to the roasted CBE, which did not show any significant effect. Moreover, supplementation with both CBEs significantly affects the volatile fatty acids concentration in the rats' cecum. Results of this study contribute to the evidence that dietary supplementation with raw and roasted CBEs can exert health-promoting effects, however further studies are necessary.

RESUMEN

This study was performed to evaluate the toxic effects of aflatoxin B2 (AFB2) on antioxidant-oxidant balance and vital parameters such as physiological, cytogenetic, and anatomical alterations in Allium cepa L. root tip cells. Toxic effects of AFB2 on vital parameters were investigated by using the changes in weight gain, germination percentage, chromosomal aberrations (CAs), mitotic index (MI), micronucleus frequency (MN), and anatomical structure. Malondialdehyde (MDA) and reduced glutathion (GSH) levels and superoxide dismutase (SOD) and catalase (CAT) activities in root cells were investigated as antioxidant-oxidant parameters. For this aim, A. cepa bulbs were seperated into five groups as negative control, positive control, and AFB2 treatment groups. In results, while the rate of germination percentage, weight gain, and MI rates decreased, MN and CA frequency increased in AFB2-treated groups compared with the negative control. Most common CAs observed in AFB2-treated groups were fragment and chromosome bridges. It was determined that in 160 µg L-1 AFB2-treated group there was a 70.8% increase in MDA and a 78.1% decrease in GSH level compared with the negative control group and these changes indicate oxidative damage. In 160 µg L-1 AFB2 treatment group, SOD and CAT activities decreased importantly due to inhibition. In anatomical examinations, it was determined that AFB2 treatment caused some anatomical damages in A. cepa root cells such as necrosis, cell deformation, and thickening in cell wall. This study showed that AFB2, which has the least data among aflatoxins, causes serious in vivo toxic effects in A. cepa root cells.

RESUMEN

BACKGROUND: Lead is a nephrotoxicant probably implicated in the rising incidence of chronic kidney injury in sub-Sahara Africa. With the prohibitive cost and unavailability of metal chelators, chronic kidney disease CKD prevention is very difficult hence the search for affordable alternative. Costus afer have been shown to be organo-protective. The present research investigated the nephroprotective effect of aqueous leaf extract of Costus afer on lead induced nephrotoxicity in male rats. METHODS: Adult male rats were weight matched into five groups of five rats each. Groups 1 & 2 serve as normal and toxic control receiving deionized and leaded (CH3COO)2Pb. 3H2O water respectively. Groups 3, 4 and 5 were administered peroral 750, 1500 and 2250 mg/kg of aqueous leaf extract of Costus afer respectively while receiving Pb2+ water ad libitum. Hematological, antioxidant and histological parameters obtained from the result serve as scientific evidence in the study. RESULTS: Costus afer treatment significantly reversed (P < 0.05) the decrease in the levels of gluthatione peroxidase (GSH-PX), superoxide dismutase (SOD), catalase (CAT), Glutathione-S-trasferase activity (GST) seen in the lead acetate only treated group. Similarly, the increased malondialdehyde (MDA) level in the lead acetate only treated group was significantly (P < 0.05) reduced in the Costus afer treated groups. There were significant (P < 0.05) decreases in serum serum level of sodium (146 ± 2.1 to 133 ± 6.0) and potassium (5.1 ± 0.4 to 4.4 ± 0.3) in lead acetate alone and treated group respectively. Also recorded was a significant (P < 0.05) decrease in serum levels of total protein and albumin (67 ± 7.9 to 47 ± 5.0 g/dl) and (45 ± 4.4 to 33 ± 5.5 g/dl) in lead acetate alone and Costus afer treated groups respectively. CONCLUSIONS: Aqueous leaf extract of Costus afer may be nephroprotective in albino rats.

RESUMEN

CONTEXT: Mentha longifolia L. (Lamiaceae), a traditional medicinal herb, has been highly valued for exhibiting antimicrobial, antioxidant and antispasmodic properties. OBJECTIVE: For the first time, the synergetic anti-inflammatory effects of deuterium depleted water (DDW) and M. longifolia essential oils (ML) were investigated in experimental sepsis. MATERIALS AND METHODS: Fifty Wistar rats were divided into 5 groups (n = 10): negative control (laparotomy), CLP, treatment groups including the combination of DDWs (15 and 30 ppm) and ML (100 mg/kg b.w) and indomethacin. At 24 h after CLP induction, lipid peroxidation (LP), glutathione (GSH), glutathione in S-transferases (GST), ferric reducing ability of plasma (FRAP), myeloperoxidase (MPO), prostaglandin E2 (PGE2), and COX-2 expression were determined in the plasma and liver tissues. RESULTS: Compared with the CLP group, the administration of DDWs and ML significantly (p < 0.05) prevented the increase of LP, COX-2 and PGE2 levels and liver enzymes. Additionally, the decreased levels of FRAP and GSH induced by sepsis were remarkably (p < 0.05) risen by the administration of DDWs and ML in comparison to the CLP group. However, no significant (p > 0.05) differences were observed regarding GST, ALP and bilirubin levels. Our results also proved the synergistic anti-inflammatory activities of the DDWs and ML. The anti-inflammatory effects of the DDWs and ML were confirmed by histopathological studies. DISCUSSION AND CONCLUSIONS: The combination of DDWs and ML exerted synergistic anti-inflammatory activity against CLP-induced sepsis possibly through modulating oxidative stress/antioxidant parameters.

RESUMEN

BACKGROUND: Antagonistic yeast and hot air treatment are two promising methods for conferring resistance to pathogenic fungi. The study assessed the effectiveness of hot-air treatment (45 °C, 4 h) and antagonistic yeast (Pichia guilliermondii at 108 CFU mL-1 ) alone or in combination on the two major postharvest diseases (Rhizopus stolonifer and Penicillium expansum), as well as the quality and antioxidant parameters in harvested peaches. RESULTS: The combination of hot-air treatment and Pichia guilliermondii had notable inhibitory effects on infections in peach fruit wounds. In addition, the individual hot-air treatment or Pichia guilliermondii could improve quality indexes to varying degrees, but the combination of the above two treatments could achieve the highest efficacy. Furthermore, compared with other groups, the combined treatment induced the highest activities of superoxide dismutase and catalase, improved the content of total phenolics and reduced glutathione most obviously. Lastly, the most significant reductions in malondialdehyde content and relative electrical conductivity were observed in the combination-treated fruit. CONCLUSIONS: The combined treatment could control fungal diseases, besides delay the decline of quality and antioxidant parameters, so as to achieve the purpose of fresh keeping for harvested peach fruit. © 2018 Society of Chemical Industry.
