RESUMEN

BACKGROUND: Individuals at higher altitudes may experience a decrease in blood oxygen levels, which can result in a variety of clinical illnesses, such as high-altitude pulmonary edema, high-altitude cerebral edema, and milder but more common acute mountain sickness (AMS). OBJECTIVE: This study aims to review the current state of knowledge related to motion sickness, the risk of AMS, and pharmacological and non-pharmacological treatments for AMS. METHODS: Several databases, including PubMed, Bentham Science, Elsevier, Springer, and Research Gate, were used to compile the data for the article following a thorough analysis of the various research findings connected to acute mountain sickness and motion sickness, along with treatments and prevention. RESULTS: This article covers the research on mountain sickness as well as every imaginable form of conventional and alternative medicine. It contains ten medicinal plants that are useful in treating mountain sickness and various other remedies. Additionally, case studies are provided. CONCLUSION: Therefore, the information in the paper will help travel medicine specialists better personalize their appropriate care for patients who travel to high-altitude locations. Additionally, all available antiemetic medications, serotonin agonists, nonsteroidal anti-inflammatory drugs, and herbal treatments for motion sickness were discussed. The prevention and consequences of acute mountain sickness are also covered in this study.

RESUMEN

Terpenoids and phenols from Trachyspermum ammi (T. ammi) have reported some pharmacological actions. The objective of the work was to isolate the active constituent, its identification by spectroscopic techniques, and evaluation of the antidiabetic and neuroprotective activity from T. ammi on STZ Wistar rats. The dried fruits of T ammi were kept in a hydrodistillation apparatus to collect essential oil. The isolated fraction went through TLC, UV, FTIR, HPLC, HRMS, C13, and 1H NMR for characterization. Two dosage concentrations from the isolated compound were prepared as 10 and 20 mg/kg for treatment groups. The groups were tested for thermal and mechanical hyperalgesia, writhing, grip strength, spontaneous locomotor test, neuromuscular coordination tests, and histopathological and lipid profile analysis. Diabetes was induced by streptozotocin (45 mg/kg i.p.) and 12 weeks of treatment-induced diabetic neuropathy in Wistar rats. Biomarkers were evaluated to understand the neuropathic protection of thymol on STZ-treated Wistar rats. The biomarker studies (SOD, NO, LPO, Na+K+ATPase, and TNF-α) further confirmed thymol's diabetic neuropathy protective action. This study suggests that isolated compound thymol was antidiabetic and neuroprotective as it has shown controlled glucose levels defensive nerve damage in STZ Wistar rats. P < 0.05 level of significance was observed in the levels of endogenous biomarkers, fasting blood glucose levels, actophotometer response, and response latency in treated groups compared to the diabetic group, whereas P < 0.001 level of significance during lipid profile levels, thermal algesia, and neuromuscular comparison tests was noted in treated groups compared to the diabetic group.

RESUMEN

INTRODUCTION: Nowadays, researchers have been attempting to use herbal products as medicines which have proven to cause lesser side effects. The fruit part of Trachyspermum ammi (L.) - Ajwain has been an integral part of the Indian medicine system with much importance in Ayurveda and Unani medicine system and is prescribed by Vaidya gurus and Hakim in raw form or as a major constituent in the powdered formulations. OBJECTIVE: This research aimed to evaluate acute and sub-acute toxicity of standardized T. ammi fruit and its anti-inflammatory property using experimental models. METHODS: The extract of herbs was spectroscopically analyzed for the estimation of the number of bioactive compounds. Then acute and sub-acute toxicity analysis of the herbal extract was performed to ensure the toxic effects, if any. Biochemical parameters like ALT, AST, ALP, etc. and histopathological analysis were determined to study the toxicity of the extract. Then, the anti-inflammatory activity of the T. ammi fruit extract employing Carrageenan and formalin-induced edema model in rats was studied. RESULTS: Ajwain seeds have a pungent smell and a characteristic odor. The powder microscopy clearly showed endosperm, unicellular warty trichomes, striated cuticle in surface view, vittae, endodermis, and vascular strand. Phytochemical tests reported the presence of carbohydrates, alkaloids, tannins, etc. and characteristic peaks in UV, Mass, NMR, FTIR and HPLC were observed for the extract. Acute and sub-acute toxicity studies did not report any toxicity, and significant anti-inflammatory action was recorded. CONCLUSION: The spectroscopic and pharmacognostic analysis has shown the strong presence of flavonoids, mineral matter, protein, phenols, saponins, carbohydrates, volatile oils, fiber, glycosides and fat. Spectroscopic study interpretations have shown the presence of compounds like thymol, para-cymene, γ-terpinene, α- and ß-pinene, carvone, limonene, saponins,, ß-phellandrene, ßfenchyl alcohol, α-thujene, ß-phellendrene, α-thujene, etc. No signs of toxicity were recorded in acute and sub-acute toxicity studies assessing the relative weight and histopathological analysis. Significant anti-inflammatory potential of T. ammi fruit extract was found and LD50 was found to be beyond 3000 mg/kg. The results of this study could be useful; in setting the quality parameters for further identification of the crude herb and preparation of the monograph.

RESUMEN

Phytopharmaceuticals have always reported vital roles in the field of medicine hence the need to investigate safe and efficient drugs for treating metabolic disorders is very significant. Roots of Selinum vaginatum have therapeutic benefits and are widely used by the people of the Rohtang region for treating diabetes and its associated complications. The present study focusses on the isolation of the bioactive from the S. vaginatum roots for estimating acute toxicity studies, anti-diabetic and diabetic neuropathy protective action along with the mechanism of action in STZ induced Wistar rats. The Selinum vaginatum roots were collected from the Rohtang region, Himalayas. Chlorogenic acid was isolated and underwent identification by UV, HPLC, 1H NMR, C13 NMR, Mass, and FTIR spectroscopy methods. Chlorogenic acid was dosed at 10 and 20 mg/kg to observe the effects on experimentally induced diabetes and with time generated diabetic neuropathic complications. Biomarkers TNF-α, superoxide dismutase, nitrosative stress, lipid peroxide profile, and membrane-bound inorganic phosphate were analyzed. Histopathological evaluation of the liver and sciatic nerve was performed for all groups. Parameters like blood glucose levels, body weight, food intake, Thermal Hyperalgesia, Writhing, Cold Hyperalgesia Responses, Mechanical hyperalgesia, Grip Strength, Spontaneous Locomotor (Exploratory) Test, Neuromuscular Coordination tests, and lipid profile analysis showcased the anti-diabetic and diabetic neuropathy protective action of the drug. Inflammation, degradation, and necrosis were found to be reduced in the liver and sciatic nerve cells of treated groups. All the biomarkers used to analyze the oxidative pathway were significantly replenished indicates that chlorogenic acid produces these effects through this pathway.
