HYPOGLYCEMIC AND LIPID LOWERING EFFECT OF AQUEOUS FRESH LEAF EXTRACT OF CHROMOLAENA ODORATA (LINN) IN ALBINO WISTAR RATS FED DIFFERENT CONCENTRATIONS OF CHOLESTEROL ENRICHED DIET

Objectives:  High lipids and carbohydrate have been seriously implicated to cardiovascular problems, which has led to several uses of medicinal plants for traditional remedies. The present study investigated the lipid lowering activity of fresh leaf extract of Chromolaena odorata in Albino wistar rats. Methods: Twenty (20) rats used for the study were grouped into four groups of five (5) rats each. Group I served as normal control, group II, III and IV served as test groups, fed 75, 108 and 148 g of cholesterol enriched diet for one week and thereafter, administered with 50, 100 and 150 mg/kg body weight of fresh leaf extract of Chromolaena odorata respectively for four (4) days. Lipid profile and blood glucose were assayed at fed state and after administration. Results showed a significant (p<0.05) increase in total cholesterol, triacylglycerol, low density lipoprotein, blood glucose concentration and body weight compared with control group in fed state.  Results: Administration with fresh leaf extract of Chromolaena odorata showed a significant (p<0.05) increase in high density lipoprotein, significant (p<0.05) decrease in blood glucose concentration, low density lipoproteins, triacylglycerol, total cholesterol and body weight of rats. The oral treatment with 50, 100 and 150 mg/kg body weight of the fresh leaf extract of this study demonstrated a general hypoglycemic and hypolipidemic activity not necessary a dose dependent pattern. Conclusion: It may therefore be concluded that the hypoglycemic and hypolipidemic activity of Chromolaena odorata taken freshly squeezed could be due to its phytochemical and antioxidants content.        Peer Review History: Received 24 February 2018;   Revised 3 March; Accepted 8 March, Available online 15 March 2018 UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. 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.

Effect of Cola acuminate on Blood Glucose and Glycosylated Haemoglobin in Wistar Rats

The levels of blood glucose and glycosylated haemoglobin (GHB) were studied in 42 Wistar rats divided into three groups; controls, group A and group B. Control rats consumed only feeds, group A consumed 0.04g of Cola acuminate, while group B consumed 0.08g of Cola acuminate mixed with their feeds daily for six consecutive weeks. Blood samples were collected weekly for analysis. Baseline values increased by 22% for blood glucose in group A and by 29% in group B. GHB also increased relatively and correlated well with blood glucose in group A (r = 0.70; P < 0.05) and in group B (r = 0.73; P < 0.05). Regular kolanut consumption elevates blood glucose and GHB levels, while withdrawal returns these parameters progressively to pre-kolanut consumption levels.
