ABSTRACT
Background: Justicia schimperiana has been used traditionally for the treatment of different diseases, including, diabetes. Yet, no in vivo study was conducted to substantiate these claims. This study aimed to evaluate the effect of Justicia schimperiana roots extract on blood glucose levels and lipid profiles in streptozotocin-induced diabetic mice. Methods: Male Swiss albino mice weighing 25-35 g were induced diabetes with 150 mg/kg of STZ. Animals were randomly grouped into six groups of five each. Group I was a normal control, Group II was a Diabetic control, Group III-V were Diabetic Mice treated with the extract (100, 200, and 400 mg/kg) respectively, and Group VI was standard control. The treatments were followed for 14 days. The FBG measurements were done on 0, 7th, and 14th days of treatment. On the 15th day, the mice were anesthetized with diethyl ether; blood samples were collected for the assessment of serum lipid profiles. The antioxidant and α-amylase inhibitory activities of the extract were also investigated in vitro using the DPPH and DNSA assay methods, respectively. The data were entered into EPI DATA version 4.6, exported to IBM, SPSS version 26.0, and analyzed using a one-way ANOVA followed by Tukey's post hoc test. P < 0.05 was considered statistically significant. Results: The hydromethanolic extract of J. schimperiana roots exhibited no toxicity up to a dose of 2000 mg/kg body weight. In the STZ-induced diabetic mice, the extract reduced blood glucose levels at all tested doses: 100, 200, and 400 mg/kg on the 14th day as compared to diabetic control. The higher dose showed maximum reduction (29.73 %, p < 0.001) on the 14th day of treatment compared to the baseline. There were significant reductions in serum TG, TC, LDL, and a significant increase in body weight and HDL compared to the diabetic control. Besides, good antioxidant and α-amylase inhibitory activity were obtained from the in vitro laboratory tests. Conclusions: Evidence from our study revealed that the root extract of J. schimperiana has antihyperglycemic and antihyperlipidemic effects in STZ-induced diabetic mice.
ABSTRACT
Obesity is defined as an abnormal or excessive accumulation of fat that increases the burden of different chronic diseases in the population. It has reached epidemic proportions and is a major risk factor for a variety of diseases, including hypertension, cardiovascular disease, type 2 diabetes, dyslipidaemia, atherosclerosis, and some malignancies. Weight gain is a result of excessive energy intake compared to energy expenditure (energy loss from metabolism and physical exercise). A ketogenic diet has a more useful effect on obesity than other diets. A ketogenic diet is a low-carbohydrate, high-fat, moderate-protein diet that induces the production of ketone bodies by mimicking the breakdown of a fasting state. The mechanism behind the ketogenic diet is still unknown, although it obviously helps people with obesity lose weight. Several pathways for the ketogenic diet effect on weight loss have been hypothesized by researchers, including reduced appetite due to effects on appetite control hormones and a possible direct appetite suppressant action of ketone bodies; reduced lipogenesis and increased lipolysis; greater metabolic efficiency; and increased metabolic costs.
ABSTRACT
Background: Managing diabetes mellitus with currently available drugs is costly, and the chances of side effects are high, leading to further studies for new and better medications from plant sources with the affordable and lower side effects. This study aimed to evaluate the anti-diabetic effects of Datura stramonium Linn (Solanaceae) Leaves Extract in Streptozotocin- Induced Diabetic Mice. Methods: Male Swiss albino mice were induced into diabetes using 150mg/kg of STZ. Mice were allocated randomly into six groups, five mice per group. Group I was a normal control, Group II was Diabetic negative control, group III was Diabetic positive control, Group IV-VI were Diabetic Mice that treated with extract (100, 200 and 400 mg/kg) for 14 days. The FBG measurements were done on 0, 7th, and 14th days of treatment. After 14th day of treatment the mice were anesthetized with diethyl ether. Then, blood was drawn by cardiac puncture to assess TC, TG, LDL-C, and HDL-C. The antioxidant activity of the extract was determined using a DPPH assay. The data were entered into Epi-Data version 4.6, exported to SPSS version 26.0, and analyzed using a one-way ANOVA followed by a Tukey post hoc test. P < 0.05 was considered statistically significant. Results: The extract of D. stramonium reduced the FBG level by 19.71%, 30.27%, 40.95%, and 45.67%, respectively, for D. stramonium 100, 200, 400, and GLC 5 mg/kg on the 14th day of treatment. Diabetic mice treated with D. stramonium for 14 days â¯â¯showed a significant decrease in serum TC, LDL, and serum TG and a significant increase in body weight, and HDL level as compared to diabetic negative control. Antioxidant activities of the leaves extract were comparable to ascorbic acid with an IC50 of 172.79 µg/mL. Conclusion: These findings revealed that the D. stramonium leaves extract possesses significant Anti-diabetic activities.
