Hypoglycemic and hypolipidemic effects of diacetodibutyl disulphide     

P. K. Joseph  R. T. Kasinath 《Indian journal of clinical biochemistry : IJCB》2000,15(2):68-75

The hyperlipidemia, fatty liver and the high levels of liver and kidney thiobarbituric acid reactive substances (TBARS) observed in rats which were fed ethanol for 45 days, could be significantly reduced by feeding diacetodibutyl disulphide (DADBDS). Ethanol-induced hypoproteinemia and the rise in serum enzymes like AST (EC 2.6.1.10), ALT (EC 2.6.1.2) and ALP (EC 3.1.3.1) could also be ameliorated by DADBDS. Feeding of this compound to normal rats did not produce any change in serum or tissue lipid levels or serum enzymes or tissue TBARS except a moderate reduction in serum triacyl glycerols. DADBDS feeding to rats maintained on a high lipid diet could also reduce the serum and tissue lipid levels and also reduce the serum transaminases. DADBDS which is an aliphatic disulphide could produce hypolipidemic effects in rats fed a single large dose of ethanol, whereas dimenthol disulphide which is an aromatic disulphide was not useful as a hypolipidemic agent. Perhaps hypolipidemic effects are shown only by aliphatic disulphides and not by aromatic disulphides. Feeding of 100 mg DADBDS per kg body weight to normal fasted rats produced a mild hypoglycemia, but higher doses produced a hyperglycemic effect. This dose of DADBDS increased the serum insulin levels and reduced blood glucose levels in fasted diabetic rats, but DADBDS feeding did not alter the serum insulin levels in fasted normal rats. DADBDS is odourless and tasteless in 1% solution and it could be a better substitute for garlic for hypoglycemic and hypolipidemic studies.  相似文献

郭英芳  卢博友 《杨凌职业技术学院学报》2011,10(3):1-4

针对现有大蒜播种机采用纯机械方式无法解决大蒜直立播种的问题,提出了用SUSAN角点检测算法的方法解决。分别对图像进行二值化、边缘跟踪,然后根据大蒜的形态特征,提出以曲率为特征量,再根据该算法的原理识别出瓣尖的位置。  相似文献   

甲醛处理对大蒜根尖细胞有丝分裂行为及微核产生的影响     

张广华  申二巧  张成合 《保定师专学报》2011,(3):54-57

以染色体较大、容易观察的大蒜为材料,研究不同体积分数的甲醛水溶液对大蒜根尖细胞有丝分裂行为和微核产生的影响.结果表明,大蒜对甲醛的毒性反应比较敏感,用0.01%~0.04%的甲醛水溶液处理4 h~12 h,细胞分裂指数较对照平均下降69.13%;处理24 h,细胞分裂完全停止,分裂指数为0;不同体积分数的甲醛处理均可诱发细胞微核的产生,频率在0.162%~0.235%;细胞分裂后期个别染色体表现落后,并随之解体、凝聚,是导致微核产生的一个重要成因.  相似文献   

A rabbit model for studying hypocholesterolemic effect of drugs and hypocholesterolemic effect of extracts of garlic (Allium sativum)     

P. Ratnakar  P. S. Murthy 《Indian journal of clinical biochemistry : IJCB》1998,13(1):8-11

An experimental model of hypercholesterolemic rabbits suitable for studying the hypocholesterolemic effect of compounds was developed. Rabbits were made hypercholesterolemic by oral administration of cholesterol (100mg/kg body weight/day) suspended in groud nut oil by gastric intubation (Ryle's tube). Cholesterol can be given to rabbits from 10 days to 6 months depending on the degree of hypercholesterolemia required and duration of study of hypocholesterolemic effect. In one month cholesterol feeding experiment, the serum cholesterol level in normal controls (not given cholesterol) was 67±11.3 mg/dl and in cholesterol fed animals 191.3±70.6 mg/dl. In 2 months experiment, besides hypercholesterolemia, abnormal serum lipid profile and increase in lipid content in liver, heart and aorta were also seen. To such animals when water and methanol extracts of garlic were given along with cholesterol, there was significant decrease in serum cholesterol level. The advantage of this method over the method in which cholesterol is mixed with diet to induce hypercholesterolemia is that exactly same and calculated amount of cholesterol can be given for each animal. This minimises the variations in serum cholesterol levels in different animals.  相似文献
