Histopathological Effect of Crude Extract of Piper Guineense (Uziza) Leaves on the Liver of Wistar Rats and on Pseudofolliculitis Barbae (After Shave Rash) in Human

This study investigated the histological and serum enzymatic activities of Azadirachta indica, an Indian medicinal plant, on the pancreas in streptozotocin induced diabetic adult wstar rats. Forty six adult wistar rats weighing 100 g to 220 g were randomly separated into four groups; Group A was regarded as the control , while group B was the diabetic group, C and diabetic – extract treated group. The control group received distilled water throughout the experiment; the remaining three groups were induced with streptozotocin intra-peritoneally to induced diabetes in the wistar rats. After some days, the animals were confirmed diabetic with the help of a measuring glucometer. Thereafter, group B diabetic rats remained untreated while Group C and D were treated with a low dose (250 mg/kg) of the crude neem bark extract and a high dose (500 mg/kg) of the extract respectively for 42 days. The aqueous neem bark extract was suspended in the drinking water of the treated animals for the period of 42 days. The body weights of the animals were weighed weekly and likewise the measurement of the blood glucose level was taken. The animals were sacrificed at the end of 42 days by cervical dislocation and the pancreas was removed and weighed immediately using sensitive weighing balance. The blood samples were collected from the sacrificed animals into EDTA bottle for serum enzymatic analysis. The organ pancreas was fixed in a 10% formol saline, processed and stained with Heamatoxylin and Eosin for general histological study. The microscopic examination of diabetic group showed some degenerative and necrotic cells which made the pancreatic tissue distorted compared with the control that appeared normal. The diabetic group C and D rats treated with the extract showed ameliorative potentials of the extract with improvement in histo-architecture of the pancreatic tissue following recovery from damage. Analysis of the blood serum level showed that the aqueous neem bark extract has ameliorative effect on the enzymatic activities in serum of the treated rats. The alanine amino transferase, aspartate amino transferase and alkaline phosphatase levels were significantly reduced (P<0.05) in the crude extract- treated animals compared with the untreated group B and control group A with significantly increased ( P<0.05 ) enzymatic activities in wistar rats in these groups. The antioxidant status was compromised in diabetic group B with significantly increased (P<0.05) LPO, reduced SOD and GSH compared with significantly reduced (P<0.05) LPO, increased (P<0.05) SOD and GSH in group A- control and Group C and D diabetic-extract treated Wistar rats. Similarly, the blood glucose level increased significantly (P<0.05) in group B diabetic group compared with significantly reduced (P<0.05) blood glucose level in group A control as well as C and D extract-treated rats. The study concluded that crude extract of neem has ameliorative potentials on streptozotocin-induced diabetic wistar rats characterized by oxidative damage which reveals improvement in tissue morphology.

Background: Diabetes mellitus is a metabolic disorder characterized by chronic hyperglycemia resulting from defects in insulin secretion, insulin action, or both. There are many classes of drugs used for treatment, and these include insulin sensitizers, insulin secretagogues, and agents that delay the absorption of carbohydrates from the bowel. This study intends to investigate the effect of crude extract from a plant from South Algeria Traganum nudatum (Chenopodiaceae) on glucose uptake in liver slices isolated from Wistar rats. Methods: The liver slices were incubated for 90 min at 37° in normoglycaemic (1g/l of glucose) and hyperglycaemic (3g/l of glucose) KRBA Krebs Ringer Bicarbonate Albumin 4% media using 24 well-polyethylene plates. In each, well different concentrations of insulin (10, 50 and 100µU/ml) and hydromethanolic crude extract (100, 200 and 500µg/ml) were added. After every 30 minutes, aliquots of the culture media were assayed for the determination of glucose left. Results: Tests showed that the glucose left after 90 minutes in the media which contained insulin at 100µg/ml was the lowest (0.44 and 1.41 )g/l in the normo and hyperglycaemic media respectively, which reflect that insulin at this concentration was the most effective on the stimulation of glucose uptake. The extract had the highest effect at 500µg/ml, the concentrations of glucose left after 90 minutes of incubation were found to be (0.38 and 1.31)g/l in the normoglycaemic and hyperglycaemic media respectively. Conclusion: From the obtained results, it can be concluded that our extract seems to have an insulin-like effect on glucose uptake in liver slices isolated from Wistar rats.

Aim: Crude extracts of Heinsia crinita leaves have been found to have antidiabetic activity. The aim of this study was to evaluate the effects of the n-hexane fraction of Heinsia crinita leaf extract on electrolyte balance and some haematological indices of alloxan-induced diabetic albino Wistar rats. Methodology: Thirty (30) albino Wistar rats of both sexes weighing 120-180g were shared into five (5) groups of six animals each. Group 1 and 2 served as the normal control (NC) and diabetic control (DC) respectively and received placebo. Groups 3, 4 and 5 were diabetic treated group, and received 500mg/kg bw Metformin, 400mg/kg bw of crude extract (HC-C) and n-hexane fraction (HC-H) of Heinsia crinita respectively. Results: The HC-H administered group, like the HC-C group, showed reversal of the observed increase in chloride ion (Cl-) and decrease in sodium ion (Na+) levels in DC group to close to those of the NC group and this effect compared well with the metformin–treated group. The HC-H group, unlike the HC-C group, did not show a reversal of the observed diabetic increase in in potassium ion (K+). The WBC count was increased in DC compared to NC. On treatment with HC–C, HC-H and metformin, the WBC count decreased significantly (P<0.05) in all the treated groups compared to DC group. The RBC count was significantly decreased (P<0.05) in DC compared to NC. Similarly, there was a decrease in haemoglobin concentration in the DC group compared to the NC group. These decreases were significantly (p<0.05) reversed towards normal on treatment with HC-C and HC-H. The reversal was comparable to that of the standard drug metformin. Similarly the diabetes induced increase in platelet counts was significantly (P<0.05) reduced towards NC values on treatment with HC-H and HC-C. Conclusion: The result show that the n-hexane fraction (HC-H), like the crude extract (HC-C), can protect against diabetes induced electrolyte imbalance and haematological disorders.
