ABSTRACT

The study aims to analyse the treatment of whey protein enriched with Stevia rebaudiana fraction in insulin secretion and its role mitigating streptozotocin-induced hyperglycemia in rats. Thus, diabetic animals were treated with whey protein enriched with S. rebaudiana fraction or with only the protein isolate or only the Stevia fraction. Insulin level in plasma was measured by radioimmunoassay and the viability of ß cells was detected by immunohistochemistry. The results showed that diabetic animals treated with whey protein enriched with S. rebaudiana fraction had a greater recovery from insulinemia, with plasma levels similar to non-diabetic animals (~ 0.13 ng/mL). In addition, the same group showed a higher number of insulin-positive pancreatic B cells (~ 66%) in immunohistochemistry analysis, while the diabetic groups treated with only the fraction of stevia or whey protein showed 38 and 59% of positive cells, respectively. These results show that the treatment may have restored the viability of streptozotocin-injured pancreatic B cells, and consequently increased insulin secretion, suggesting whey protein enriched with S. rebaudiana fraction can be used an adjunct/supplement in diabetic treatment.

ABSTRACT

Cannabidiol (CBD), a compound obtained from Cannabis sativa, has wide range of therapeutic properties, including mitigation of diabetes and neurodegeneration. Cerebral ischemia and consequent learning disabilities are aggravated in elderly diabetic subjects. However, there are no studies showing the effect of CBD treatment in elderly diabetes patients suffering cerebral ischemia. The present work tested the hypothesis that CBD treatment improves metabolic dysfunctions in middle-aged diabetic rats submitted to chronic cerebral hypoperfusion. In this work, 350-day-old male Wistar streptozotocin-induced diabetic rats were used. To induce cerebral ischemia was used a chronic cerebral hypoperfusion (CCH), surgically, via the four-vessel occlusion/internal carotid artery (4-VO/ICA). Four diabetic groups were established: Non-CCH Treated Diabetic (DNT), CCH Treated Diabetic (DCT), Non-CCH Vehicle Diabetic (DNV), and CCH Vehicle Diabetic (DCV). Vehicle groups were not treated with CBD. The animals were treated during 30 days with 10 mg CBD/Kg bw/day. After treatment, the animals were euthanized, and blood levels of glucose, insulin, total cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), triglycerides, fructosamine, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were evaluated. DCT group presented reduction of hyperglycemia and an increase of insulinemia. Also was observed lower fructosamine, LDL, HDL, triglycerides and total cholesterol levels. AST and ALT concentration were reduced in CBD treated groups. CBD may be used as therapeutic tool to protect metabolism against injuries from diabetes aggravated by cerebral ischemia.
