RESUMO

The present study aimed to determine the antibacterial, antioxidant, cytotoxic activities and element levels of Verbascum lasianthum Boiss. ex Bentham. The free radical scavenging activity, total phenolic content, total antioxidant capacity, total oxidant capacity levels were analyzed as the antioxidant parameters. Seven bacteria and one yeast strains were used to determine the antimicrobial activity. The cytotoxic effects of plant extracts were determined using A549, MCF-7, HepG2 and SH-SY5Y cell lines. The findings demonstrated that the antioxidant activity increased with an increase in the phenolic content of extracts. This species is rich in bio-elements such as Fe, Cu, Mn, Zn, and Mg. Different concentrations of extracts could have antibacterial activity. This plant had an apparent cytotoxic effect only in the A549 cell line and increased the proliferation in other cell lines. The findings demonstrated that plant could be used alone or as a supplement to the current treatment protocols in diseases due to their antioxidant, antibacterial and cytotoxic effects. However, it is recommended that Verbascum L. species intended for use in therapy should be procured from areas where there is no soil pollution or organic farming is preferred.

RESUMO

Sciaena umbra is a species of fish with large otoliths. These otoliths are used for treatment of kidney stone disease with high morbidity among the public. In present study, the first group was determined as a control. Group 2 was applied to rats by adding 1% ethylene glycol to drinking water. Group 3 rats were given 50 mg/kg otolith by gavage daily. Group 4 rats were administered by adding ethylene glycol and otolith was given. Group 5 rats were added ethylene glycol for the first 30 days. Then next 15 days, the rats were given only otolith. the Serum CREA and BUN levels and urine calcium, phosphate and pH levels were determined to be damaged by ethylene glycol. Free radicals and oxidative damage caused by ethylene glycol were determined from oxidative/antioxidative parameters. Ethylene glycol has also been shown to be inflammatory. There is no positive effect on oxidative stress. From the levels of TNF-α and IL-1ß in renal tissue, SUO has shown the triggering effect of inflammation. All data indicate that otolith is not an agent that can be used in nephropathy in the kidney. It is thought that caution should be exercised regarding its use.

RESUMO

The present study aimed to determine the antioxidative and anti-inflammatory effects of safranal on damage induced by CCl4. Experimental animals were divided into five groups. The first group was determined as the control group and no treatment was conducted. Second group rats were administered 1 mL/kg-day CCI4 during the experiment. Rats in Groups 3, 4 and 5 were administered 1 mL/kg-day CCI4 and 25 mg/kg, 50 mg/kg; 100 mg/kg safranal, respectively via gavage. Oxidative-antioxidant parameters, liver function enzymes and inflammatory cytokine levels were determined in liver samples obtained from the rats. Data analysis demonstrated that oxidative stress and inflammation markers were significantly higher in CCI4 administered groups (p<0.05). Antioxidant parameters in high-dose safranal administered groups were not different when compared to the control group. Safranal had ameliorating effects on the increased liver function enzymes activities in CCI4 administered groups. In conclusion, it was observed that CCI4 administration led to hepatic damage and increased oxidative stress and inflammatory cytokine levels. It was observed that particularly high-dose administration of safranal promoted the antioxidant system. Safranal administration was not effective on IL-1ß levels. However, high-dose (100 mg/kg) safranal was found to be inflammatory against TNF-α and IL-6 cytokines. In conclusion, it can be said that safranal has an anti-inflammatory potential and has a strong antioxidative effect.

RESUMO

OBJECTIVE: In this study, anti-inflammatory effects of Royal Jelly were investigated by inducing renal inflammation in rats with the use of ethylene glycol. For this purpose, the calcium oxalate urolithiasis model was obtained by feeding rats with ethylene glycol in drinking water. MATERIALS AND METHODS: The rats were divided in five study groups. The 1st group was determined as the control group. The rats in the 2nd group received ethylene glycol (1%) in drinking water. The rats in the 3rd group were daily fed with Royal Jelly by using oral gavage. The 4th group was determined as the preventive group and the rats were fed with ethylene glycol (1%) in drinking water while receiving Royal Jelly via oral gavage. The 5th group was determined as the therapeutic group and received ethylene glycol in drinking water during the first 2 weeks of the study and Royal Jelly via oral gavage during the last 2 weeks of the study. RESULTS: At the end of the study, proinflammatory/anti-inflammatory cytokines, TNF-a, IL-1ß and IL-18 levels in blood and renal tissue samples from the rats used in the application were measured. CONCLUSION: The results have shown that ethylene glycol does induce inflammation and renal damage. This can cause the formation of reactive oxygen species. Royal Jelly is also considered to have anti-inflammatory effects due to its possible antiradical and antioxidative effects. It can have positive effects on both the prevention of urolithiasis and possible inflammation during the existing urolithiasis and support the medical treatment.
