Hypoglycemic effect of the aqueous extracts of lupinus albus, medicago sativa [seeds] and their mixture on diabetic rats

The number of people suffering diabetes mellitus is increasing worldwide at an alarming rate. A huge number of populations in the world are entirely dependent on traditional medications. This practice may be due to their safety, effectiveness, and availability as well as their fewer side effects when compared to the synthetic hypoglycemic agents. The present study was carried out to investigate and compare the activity of Lupinus albus [seeds], Medicago sativa [seeds] and the mixture of both plants seeds on some biochemical, hematological and histological parameters in alloxan-induced diabetic rats. Twenty-five male adult albino rats were divided into two groups: group 1: control group [five animals] and group 2: alloxan induced diabetic rats. Diabetic rats were further divided into four subgroups, five animals each. Subgroup1: diabetic untreated rats; subgroup 2: diabetic rates treated with aqueous extract of Lupinus albus seeds; subgroup 3: diabetic rats treated with aqueous extract of Medicago sativa seeds; and finally subgroup 4: diabetic rats treated with aqueous extract of the mixture of Lupinus albus and Medicago sativa seeds. After thirty days of treatment all rats were sacrificed, blood sample were collected to estimate some biochemical and hematological parameters. Liver samples were collected to determine their glycogen content and pancreatic samples were obtained and processed for microscopic and quantitative evaluation. In diabetic group, there was reduction in body weight's, hyperglycemia, hypoinsulinemia, significant increase in some parameters of liver and kidney functions as well as significant changes in lipids profile and proteins level with significant decreased liver glycogen content. All treated groups restored most of the mentioned parameters to their normal values. Moreover, these treatments recorded partial improvement in the histopathological changes produced by alloxan. The aqueous extract of Lupinus albus or Medicago sativa [seeds] or by their mixture has hypoglycemic and hypolipidemic effects by increasing insulin level and decreasing insulin resistance. In addition, they ameliorate most complications of diabetes

Antidiabetic and antihyperlipidemic effect of balanites aegyptiaca seeds [aqueous extract] on diabetic rats

Type II diabetes mellitus is increasing health problems that negatively affect health care systems worldwide. There is a constant urge to develop new therapies with better effects, lower side effects at lower prices to treat this disease. Therefore, the present study carried out to investigate whether Balanites aegyptiaca [seeds] could treat the hyperglycemic, dislipidemic, liver, and kidney toxicity and the pancreatic damage in diabetic rats. Fifteen adult male albino rats were divided into two groups; group 1: control group, group 2: alloxan induced diabetic rats that divided into two subgroups; subgroup1: diabetic untreated rats, subgroup2: diabetic treated with aqueous extract of B. aegyptiaca [seeds]. After thirty days of treatment, all rats were sacrificed. Blood sample were collected to estimate some hematological and biochemical parameters. Liver samples were collected to determine their glycogen content and pancreatic samples were obtained and processed for microscopic and quantitative evaluation of, alpha, beta and delta-cells number. Diabetic group recorded reduction in body weight's gained, hyperglycemia, hypoinsulinemia, significant increase in some parameters of liver and kidney functions, dislipidemia, changes in proteins level and decreased liver glycogen content. While, treatment with B. aegyptiaca [seeds] was ameliorated most of the toxic effects of alloxan and showed partially improvement in histological changes produced by alloxan. The aqueous extract of B. aegyptiaca [seeds] has hypoglycemic, hypolipidemic effects, increasing insulin level, and decreasing insulin resistance. Moreover, ameliorate the most complication associated with diabetes mellitus

Effect of camel milk on alloxan-induced diabetic rats

Diabetes is a chronic metabolic disease which affects large number of population all over the world. Such disease is associated with many complications which may leads finally to patient's mortality. Camel milk supplementation reduces the insulin requirement in Type I diabetic patients. So this study was planned to evaluate the effect of camel milk as hypoglycemic agent. Thirty male adult albino rats were used to investigate the effect of camel milk [CM] treating diabetic rats. Rats were divided into three equal groups, control, diabetic non treated and diabetic CM treated groups. After thirty days of treatment all rats of each group were sacrificed. The body weight of each rat was determined at the beginning and the end of each period. Blood glucose, serum insulin, lipid and protein profiles, liver and kidney functions, blood picture and liver glycogen were determined for each rat at the end of each period. Pancreatic samples were obtained and processed for microscopic and quantitative evaluation after staining the prepared sections with both Heamatoxylin and eosin as well as special stain for demonstration of the different pancreatic cells in the Islet of Langerhans. The obtained results showed that the induced diabetes was diagnosed by laboratory assessment to body weight loss, hyperglycemia, and hypoinsulinemia, significant increase in liver and kidney functions, lipid and protein profiles and decreased liver glycogen content. While, CM treatment led to a significant improvement in all these parameter except liver function. Microscopically there was definite vaculation, degeneration, karyolysis and pyknosis of beta pancreatic cells in diabetic group while the other pancreatic cells were not affected [alpha and delta cells]. The use of CM treatment of this study greatly improves such cellular changes. It was recommended that the use of the CM as a hypoglycemic agent may be of good results besides repeating such study with the use of variable doses may be helpful in better evaluation for the required doses
