Lipid Profiles, Glycated Hemoglobin, and Diabetes in People Living at High Altitude in Nepal.

This study aimed to describe lipid profiles and the distribution of glycated hemoglobin (HbA1c) in a sample of a high altitude population of Nepal and to explore associations between these metabolic risk variables and altitude. A cross-sectional survey of cardiovascular disease and associated risk factors was conducted among 521 people living at four different altitude levels, all above 2800 m, in the Mustang and Humla districts of Nepal. Urban participants (residents at 2800 m and 3620 m) had higher total cholesterol (TC) and triglyceride (TG) than rural participants. A high ratio of TC to high-density lipoprotein-cholesterol (HDL) (TC/HDL ≥ 5.0) was found in 23.7% (95% CI 19.6, 28.2) and high TG (≥1.7 mmol/L) in 43.3% (95% CI 38.4, 48.3) of participants overall. Mean HbA1c levels were similar at all altitude levels although urban participants had a higher prevalence of diabetes. Overall, 6.9% (95% CI 4.7, 9.8) of participants had diabetes or were on hypoglycaemic treatment. There was no clear association between lipid profiles or HbA1c and altitude in a multivariate analysis adjusted for possible confounding variables. Residential settings and associated lifestyle practices are more strongly associated with lipid profiles and HbA1c than altitude amongst high altitude residents in Nepal

The effect of variation of parameters on the reaction has been investigated. 2-Cyclohexyl-4-methylphenolwas further converted to 2, 6-dicyclohexyl-4-methylphenol.</span

Studies on locally available three anti-diabetic herbal medicines

Herbal medicines are being used for the treatment of different diseases for centuries. Sustainable development of herbal medicines need the study of their safety, efficacy and standardization are essential. Two commercially available herbal medicines i.e., Ziabetes (dolabi) and Jambadayrist, and a folkloric medicine prepared from four plant materials by a local practitioners were investigated for their chemical compositions.  Four compounds were isolated from the extracts of these medicines by silica gel column chromatography. Oleic acid and p-hydroxycinnamic acid were isolated from the aqueous 80%ethanol extract of the folkloric medicine whereas benzoic acid was found to be present in Ziabetes and Jambadayrist. The present investigation revealed that excessive amount of benzoic acid (or sodium benzoate) is being added as preservative in commercial herbal medicines

ANTIHYPERGLYCEMIC EFFECT OF BRIDELIA NDELLENSIS ETHANOL EXTRACT AND FRACTIONS IN STREPTOZOTOCIN-INDUCED DIABETIC RATS

The effects of the ethanol extract (1.25 g/kg) and fractions (1 g/kg) of Bridelia ndellensis stem bark on the blood glucose levels in streptozotocin-induced types 1 and 2 diabetic rats at different prandial states were studied. The ethanol extract of B. ndellensis had no hypoglycemic effect in type 1 diabetic rats in fasting and postprandial glucose load conditions and, in type 2 diabetic rats in fasting condition. However, the extract, and its ethyl acetate and dichloromethane fractions significantly lowered blood glucose levels in type 2 diabetic rats when fed simultaneously with glucose. The active principles responsible for the antihyperglycaemic effect are concentrated in the ethyl acetate and dichloromethane fractions of the extract
