The present study was designed to investigate the hypoglycaemic and hypolipidaemic activities of Qurs-e-Ziabetus 16 (QZ-16) in Streptozotocin (STZ) induced diabetic rats. QZ-16, a polypharmaceutical herbomineral formulation developed on the principles of Unani medicine is used for non-insulin dependent diabetes mellitus (NIDDM). The elevated levels of fasting blood glucose, serum levels of cholesterol, triglycerides and urea observed in rats treated with STZ (55 mg/kg body wt.) were significantly reduced by the treatment of QZ-16 (240 mg/kg, p.o.) and gliclazide (30 mg/kg, p.o.). The reduced HDL cholesterol levels were also increased by the QZ-16 and gliclazide treatments in the STZ induced diabetic rats. These data show that QZ-16 has hypoglycaemic, hypolipidaemic properties in STZ induced diabetic rats.

The present study is aimed at finding the effect of B-20 drops, a homoeopathic formulation, in streptozotocin (STZ) induced diabetic rats. B-20 drops comprises of the constituents derived from plants and other natural sources, and are generally prescribed by the homoeopathic physician, in cases of hyperglycemia and diabetes. The elevated levels of fasting blood glucose and pancreatic lipid peroxides observed in rats treated with STZ were significantly reduced by the treatment of B-20 drops. The reduced liver glycogen contents were also brought back to near normal level by B-20 drops treatment in STZ diabetic rats. STZ induced histopathological changes in pancreas and liver was also partially reversed by B-20 drops. The findings indicate that B-20 drops help in improving the glycogen stores in the liver and prevents STZ induced damage through free radicals by decreasing the pancreatic lipid peroxides levels.

Free radicals are known to play important role in pathophysiology of hepatic disorders and antioxidants are employed along with other chemotherapeutic agents in treatment of such diseases. In search of natural antioxidant, successive extracts of Hypericum (H.) hookerianum (Family: Hypericaceae) were evaluated by in vitro and in vivo methods. Extracts of aerial parts of H. hookerianum were subjected for 1,1-diphenyl 2-picryl hydrazyl radical scavenging activity (DPPH assay), nitric oxide radicals scavenging assay and thiobarbituric acid reactive substances (TBARS) assay. Methanolic extract was found to be more active than other extracts in DPPH and in vitro TBARS assay with IC50 at 5.82 ± 1.33 μg/ml and 49.78 ± 3.79 μg/ml respectively. While petroleum ether extract showed more potentials in scavenging the nitric oxide radicals with IC50 220.97 ± 2.69 μg/ml. The administration of CCl4 to the control animals caused decrease in the level of catalase and superoxide dismutase, together with significant increase in the level of TBARS in liver and kidney. Reversal of these changes towards normal group was observed by administration of H. hookerianum methanolic extract at 50 and 100 mg/kg body weight, while other extracts were found to be less active.

Positive association exists between abdominal obesity and asthma: Evidence from a meta-analysis of cohort studies

( Md Salman Hussain ),( Abul Kalam Najmi ) 대한결핵 및 호흡기학회 2019 대한결핵 및 호흡기학회 추계학술대회 초록집 Vol.127 No.0

Purpose: Asthma is the most common respiratory disease affecting more than 350 million people worldwide. Epidemiological studies found an association between asthma and abdominal obesity. However, the published evidence presented conflicting findings. So, this study is aimed to assess the association between abdominal obesity and asthma. Method: A Literature search was performed in databases including PubMed, and Embase from inception to July 2019. Two investigators independently retrieved the literature, extracted the data and assess the study quality using the Newcastle-Ottawa Scale. The primary outcome was to assess the association between abdominal obesity and asthma. Secondary outcomes include subgroup analysis based on gender. Review Manager version 5.3 was used for the statistical analysis. Results: This meta-analysis was based on five cohort studies with a total of 39533 patients. Included studies were of high quality. Abdominal obesity was assessed based on the waist circumference in all the included studies. The pooled analysis found a significant positive association between abdominal obesity and asthma with an odds ratio of 1.66 (95% CI: 1.30 - 2.15), p= <0.0001 (Fig.1). Subgroup analysis based on the female population found a significant positive association between abdominal obesity and asthma with a pooled odds ratio of 1.30 (95% CI: 1.04 - 1.63), p= 0.02. Whereas, a non-significant association exists when the data were pooled for the male population with an odds ratio of 1.66 (95% CI: 0.78 - 3.52), p= 0.19. Conclusion: We found a positive association between abdominal obesity and asthma. Future large epidemiological studies are warranted to make the evidence more robust.

Protective effect of silymarin in streptozotocin-induced diabetic dyslipidaemia in rats

Sharma, Manju,Pillai, K.K.,Anwer, Tarique,Najmi, Abul Kalam,Haque, Syed Ehtaishamul,Sultana, Yasmin Kyung Hee Oriental Medicine Research Center 2010 Oriental pharmacy and experimental medicine Vol.10 No.3

The present study investigated the effect of silymarin, a flavonoid, on streptozotocin (STZ) - induced diabetic dyslipidaemia in rats. Experimental diabetes was induced by a single intraperitoneal injection of STZ (60 mg/kg). Silymarin (25 mg/kg and 50 mg/kg) was orally administered to diabetic rats for a period of 15 days. Blood glucose levels, serum lipid profile and liver glycogen levels were estimated following the established procedures. Biochemical observations were supplemented with histological examination of liver sections. Oral administration of silymarin to diabetic rats significantly (P < 0.001) decreased the blood glucose levels ($259.99{\pm}23.64$ vs. $99.90{\pm}2.62$ [25 mg] & $89.17{\pm}3.32$ [50 mg]). The most interesting finding was the significant (p < 0.001) increase in HDL-cholesterol levels ($26.99{\pm}0.61$ vs. $40.55{\pm}0.52$ [25 mg] & $41.12{\pm}0.37$ [50 mg]) whereas, there was a significant decrease in serum total cholesterol (TCh), triglycerides (TG), low density lipoprotein (LDL) and very low density lipoprotein (VLDL) cholesterol levels observed in silymarin treated diabetic rats. STZ treatment caused significant degeneration of liver parenchyma, which was normalized to near normal morphology by administration of silymarin. The findings indicate that silymarin effectively improved the overall lipid profile and restored the glycogen stores in the liver of STZ-induced diabetic rats, in a dose dependent manner. The results indicate existence of abnormalities in lipid metabolism in STZ-induced diabetic rats and suggest a protective effect of silymarin in this animal model.
