Effect of hibiscus sabdariffa l. Piper nigrum l. And zingiber officinale r. Extract on serum electrolytes profile and changes in the pancreas of alloxan induced diabetic rat.

Abstract

Diabetes Mellitus (DM) is the most common endocrine disease which is characterized by hyperglycaemia, altered metabolism of lipids, carbohydrates and protein with an increased risk of many complications such as liver and pancreas damage and altered serum electrolytes level. During the past few years many plants and spices have been used to manage DM. This work aimed to investigate the possible anti-diabetic effect of Hibiscus sabdariffa L., Zingiber officinale roscoe and Piper nigrum L. extract treatments in alloxan induced diabetic rats via studying pancreas, liver structure abnormalities and serum electrolytes level alteration. 30 male Wistar rats (130-180 g) were injected intraperitoneally and divided into five main groups each of 6 rats. The control group was injected with a single dose of saline solution (0.9% NaCl), diabetic group was injected with a dose of alloxan solution (170 mg/kg), high and low dose of 250 mg/kg and 500 mg/kg extract after induction of diabetes respectively and metformin treated group was injected at a daily dose 500 mg/kg metformin after induction of diabetes. Microscopic histopathology examination of pancreatic tissues showed decrease in islets of Langerhans size in the diabetic group, sinusoidal enlargement and increased fatty vacuoles in the liver tissues of the diabetic group. There were alterations in the serum electrolytes levels of the diabetic group. These abnormalities were healed after treatment of diabetic rats with extract which could have the ability to regenerate beta cells of islets of Langerhans. The present study could verify that the extract normalized the various serum electrolytes levels and histological abnormalities resulted due to diabetes metabolic disorders.

Hypoglycemic effect of leafy vegetables from Ankole and Teso sub-regions of Uganda: preclinical evaluation using a high fat diet-streptozotocin model

“…Hs leaf Zinc oxide nanoparticles were able to reduce blood glucose levels in mice up to 59.6% [22]. A methanol extract of a combination of Hs leaves and other medicinal plants (Piper nigrum and Zingiber o cinale) showed a signi cant reduction of blood glucose compared to Metformin in a study conducted by Ime et al, (2022) [23]. An in-vitro study of the leaf extract of different cultivars of Vu revealed an improvement in diabetic parameters through inhibition of digestive enzymes like α-glucosidase and α-amylase, up to 94% compared to the commercial inhibitor Acarbose.…”
