Trichosanthes dioica mediated biochemical alterations in STZ induced diabetic rats

Secondary disorders in consequences to diabetes involves the development of several diseases in the oral cavity, as periodontitis, xerostomy, infection by diverse pathogens and dysfunctions on the salivary secretion. These alterations occur partially, in consequence of the oxidative stress occasioned by hyperglycemia, and are important in patients undiagnosed or that have flaws in their therapeutic process. The aim of this work was to evaluate biochemical alterations of submandibular glands in response to oxidative stress during diabetes mellitus, and verify the effects of N-acetylcystein supplementation to diabetic rats, specially on the regulation of modifications related to glutathione and thiol proteins. For this purpose, the levels of some oxidative stress markers and the occurrence of the post-translational event of S-glutathionylation were evaluated. The a-amilase degranulation by isolated acinar cells and glandular relative weight was also measured for each experimental group. The compound was able to decrease the lipoperoxidation and proteic oxidation observed in the submandibular gland of diabetic rats, preventing the decrease of the tecidual reducing power and increasing the occurrence of the post-translational process of S-glutathionylation. The diabetic condition increases the degranulation of a-amilase and the glandular weight, but the supplementation with N-acetylcystein did not affect these events. Together these findings may help to elucidate the status of oxidative stress on salivary glands and suggest new therapeutic strategies employing antioxidants of low molecular weight to prevent oral and systemic dysfunctions related to diabetes.

We used the bone marrow DNA strand breaks, micronucleus formations, spermatocyte chromosomal aberrations, and sperm characteristic assays to investigate the chromosomal instability in somatic and germinal cells of diabetic rats treated with multiple doses of naringin. The obtained results revealed that naringin was neither cytotoxic nor genotoxic for the rats at all tested doses. Moreover, naringin significantly reduced the diabetes-induced chromosomal instability in somatic and germinal cells in a dose-dependent manner. In addition, diabetes induced marked biochemical alterations characteristic of oxidative stress including enhanced lipid peroxidation, accumulation of oxidized glutathione, reduction in reduced glutathione, and accumulation of intracellular reactive oxygen species. Treatment with naringin ameliorated these biochemical markers dose-dependently. In conclusion, naringin confers an appealing protective effect against diabetes-induced chromosomal instability towards rat somatic and germinal cells which might be explained partially via diminishing thede novofree radical generation induced by hyperglycemia. Thus, naringin might be a good candidate to reduce genotoxic risk associated with hyperglycemia and may provide decreases in the development of secondary malignancy and abnormal reproductive outcomes risks, which seems especially important for diabetic patients.

Objective: To evaluate the antidiabetic and enzymatic antioxidant effects of ethanolic extracts of leaf and fruit of Trichosanthes dioica and leaf of Clitoria ternatea in streptozotocin (STZ)-induced diabetic rats.Methods: Male adult albino rats of Wistar strain equally divided into 11 groups of six rats each were assigned into non-diabetic and diabetic groups. Diabetes was induced in experimental animals by single dose intraperitoneal administration of STZ at a dose of 60 mg/kg body weight. Group I and II which served as non-diabetic and diabetic controls, respectively, received placebo treatment. The diabetic test Groups III to X were treated with either individual and combined ethanolic extracts of plant materials T. dioica and C. ternatea (200 and 400 mg/kg bw) and Group XI was treated with glibenclamide (600 μg/kg bw) for 28 days consecutively. After completion of experimental duration, the animals were sacrificed and collected serum, liver, and kidney were used for the evaluating therapeutic effects on the STZ-induced diabetic rats.Results: The ethanolic extracts of T. dioica (leaf and fruit) and C. ternatea (leaf) and glibenclamide significantly reduced the levels of lipid peroxidation (LPO) and significantly increased the activities of enzymatic antioxidant markers superoxide dismutase, catalase, and glutathione peroxidase in serum, liver, and kidney of diabetic rats.Conclusions: From the present study, it can be concluded that the combined extract of T. dioica fruit and C. ternatea leaf was found to be more effective in treating diabetes and increased activities of enzymatic antioxidants in diabetic-treated rats substantiate that the investigated drugs do extend a clear protective action against LPO in STZ-induced diabetic rats.

Biochemical Alterations

Renal hypertrophy was induced in 100 g male rats by the injection of 250 mg folic acid (FA) dissolved in 0.3 M NaHCO3/kg body weight (i.v.). Preliminary studies of the biochemical alterations in ribonucleic acid (RNA) metabolism of the renal tissue have been reported recently (1). They are: RNA content and concentration, orotic acid-c14 incorporation into RNA and acid soluble nucleotide pool, intracellular localization of the newly synthesized RNA, and the specific activity of enzymes of the de novo pyrimidine biosynthesis pathway. The present report describes the light and electron microscopic observations in these animals. For light microscopy, kidney slices were fixed in formalin, embedded, sectioned, and stained with H & E and PAS.

Some investigators feel that insulin does not enter cells but exerts its influence in some manner on the cell surface. Ferritin labeling of insulin and insulin antibody was used to determine if binding sites of insulin to specific target organs could be seen with electron microscopy.Alloxanized rats were considered diabetic if blood sugar levels were in excess of 300 mg %. Test reagents included ferritin, ferritin labeled insulin, and ferritin labeled insulin antibody. Target organs examined were were diaphragm, kidney, gastrocnemius, fat pad, liver and anterior pituitary. Reagents were administered through the left common carotid. Survival time was at least one hour in test animals. Tissue incubation studies were also done in normal as well as diabetic rats. Specimens were fixed in gluteraldehyde and osmium followed by staining with lead and uranium salts. Some tissues were not stained.
