Aim and objective: Clerodendrum thomsoniae leaves are used in Cameroon to manage diabetes and its related disorders. The study aimed at investigating the antidiabetic effect of the aqueous extract on diet and dexamethasone induced diabetic rats. Methods: Young mature leaves of C thomsoniae were dried, finely powdered and submitted to aqueous extraction. The dehydrated extract was tested in rats at 3 doses 312.5, 625 and 1250 mg/kg based on the local use of the plant. The effect of the extract on the fasting blood glucose in normoglycemic rats and MACAPOS 1 type diet induced diabetic rats, using respectively glibenclamide and metformin as positive control groups, were investigated. Results: AECT significantly reduced blood glucose levels in normoglycemic rats (p<0.05) two hours after administration, from 83±2 mg/dL to 57.39±1.7 mg/dL with the dose of 1250 mg/kg. given the highest reduction rate of 30.86%. In normoglycemic rats 30 minutes after oral glucose overload, the maximum reduction rate was observed with glibenclamide 5 mg / kg and calculated at 49.90% followed by 36.39%, for the extract at 1250 mg / kg. After 30 days of repeated oral administration, AECT produced a reduction on blood glucose levels (p<0.05) in type 2 diabetic rats. This reduction in blood sugar was much more expressed with the dose of 1250mg/kg (73.52±0.71 mg/dL) followed by metformin 38mg/kg (70.21±0.89 mg/dL) as the normal control with no significant difference (P < 0.05). Conclusion: These results show that the antidiabetic activity of AECT can be explained by insulin stimulating effect, also give support to the traditional use of this plant.

The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.

Background: The genus Clerodendrum is among the most important in the plants' kingdom with many species known for their medicinal properties and among which is well represented. Previous studies Clerodendrum thomsoniae established hypolipidemic, antioxidant and antidiabetic properties of aqueous extract (AECT) of Clerodendrum thomsoniae.This study aimed at evaluating the effect of the AECT on the onset of hyperlipidaemia in wistar Objective: rats.Normal Wistar rats were administered AECT (312.5, 625 and 1250 mg/kg, p.o.) followed Material and methods: by feeding with high fat diet for five weeks. Lipid parameters such as total cholesterol (TC), Low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and triglycerides (TG) levels were measured in serum. The modifications in the body mass, feed intake were evaluated. The results revealed that HFD induced an alteration in serum, lipid profile (triglyceride, cholesterol, HDL, and LDL) in negative control rats. Meanwhile in rats subjected to AECT (312.5, 625 and 1250 mg/Kg p.o) no significant changes were noticed with the normal control rats (p 0.05). On the other hand, concerning body mass, no significant change was observed between the normal control < and test rats. AECT showed the ability to prevent the onset of hyperlipidaemia in rats. Hence, it could be used in the management of cardiovascular diseases, obesity and metabolic syndrome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
