Bersama Abyssinica

Background: Diabetes mellitus is one of the major and common metabolic, and chronic disorders in the world. Several medicinal plants have been used globally for the management of diabetes mellitus. The current study aimed to study the anti-hyperglycemic and anti-hyperlipidemic effects of Bersama abyssinica. Methods: Antidiabetic effect of 80% methanolic crude extract of Bersama abyssinica was studied in repeated dose-treated STZ-induced diabetic mice model. The activities of Bersama abyssinica on serum lipid level and body weight were investigated on STZ-induced diabetic mice. Data were analyzed using one-way ANOVA and significant when the p-value was less than 0.05. Results: All doses of the crude 80% methanolic extract of Bersama abyssinica (100 mg/kg, 200 mg/kg, and 400 mg/kg) exhibited a noticeable BGL reduction when compared with baseline blood glucose level and diabetic control on the 7th and 14th days of administration. Moreover, the higher dose of the extract (at 400 mg/kg) significantly (p < 0.001, 54.3%) decreased the BGL in STZ-induced diabetic mice. The maximum decrement in fasting BGL was achieved at the 14th days: 34.92%, 41.10%, 54.30%, and 59.66%, respectively for BAC 100 mg/kg, BAC 200 mg/kg, BAC 400 mg/kg, and GLC 5 mg/kg treated groups. Bersama abyssinica also displayed a significant (p < 0.05) improvement of serum lipid levels and body weight. Conclusion: Bersama abyssinica crude extract exhibited a significant antidiabetic effect and prevented body weight loss in streptozotocin-induced diabetic mice. The finding also confirmed the valuable biochemical activity of Bersama abyssinica by improving serum lipid levels.

Bersama Abyssinica

Background. The leaves of Bersama abyssinica are used for the treatment of diabetes mellitus in folk medicine system of Ethiopia. The present study was done based on the traditional claim of B abyssinica for the treatment of diabetes mellitus. Methods. The α-amylase inhibition and antioxidant activities of B abyssinica extracts were evaluated by using 3,5-dinitrosalicylic acid method and diphenyl-2-picrylhydrazyl assay model, respectively. Blood glucose lowering activity of the extracts was studied in 4 animal models; normoglycemic, oral glucose loaded, and streptozotocin-induced diabetic mice models. Results. Among the extracts, the crude extract showed the highest α-amylase enzyme inhibition activity with an IC50 of 6.57 μg/mL. The water fraction showed the strongest antioxidant activity with an IC50 of 3.43 μg/mL. The crude extract at doses of 200, and 400 mg/kg showed significant ( P < .05) hypoglycemic activity in normoglycemic mice. All doses of the crude extract significantly ( P < .05) reduced blood glucose levels of oral glucose-loaded mice. In streptozotocin-induced diabetic mice models, both the crude and solvent fractions showed a significant ( P < .05) blood glucose lowering effect as compared with the negative control group post 8 hour treatment. Conclusion. The results demonstrated the beneficial biochemical effects of B abyssinica extract by inhibiting α-amylase and scavenging the free radicals. The crude extract and solvent fractions of B abyssinica had significant blood glucose lowering effect in all animal models.

Beta Glucan food supplements have been reported to be of benefit in diabetes and hyperlipidemia. We report a pilot study of the effects of Nichi Glucan, 1, 3-1, 6 Beta Glucan food supplement, in lowering the blood glucose and lipid levels in three patients with noninsulin-dependent diabetes mellitus (NIDDM) from India. These patients had increased blood glucose and lipid levels inspite of routine antidiabetic and lipid level lowering medications. Each of the participants took 1.5 g of Nichi Glucan per day with food for two months along with their routine medications. The relevant parameters to assess glycemic status and lipid levels were calculated at the baseline and at the end of two months. After two months of continuous consumption, in one patient, the HbA1c decreased from 9.1% to 7.8%, and the glycemic target of HbA1c <6.5% laid down by the International Diabetes Federation was reached in two patients. Lipid levels also decreased significantly. Based on our findings, Nichi Glucan food supplement can be considered along with routine medications in patients with Type II diabetes with hyperlipidemia. Further studies are needed to validate the results.

Abstract Background Diabetes mellitus (DM) is currently a major health problem and the most common chronic disease worldwide. Traditional medicinal plants remedies remain a potential adjunct therapy to maintain better glycemic control while also imparting few side-effects. Arbutus unedo L. has been traditionally used to manage several diseases including diabetes. This study was undertaken to contribute the validation of the traditional use of Arbutus unedoL. (Ericaceae) in the treatment of diabetes. Methods In-vitro antidiabetic effect of the A. unedo roots aqueous extract was conducted using α-glucosidase and α-amylase assays. While in-vivo antidiabetic activity was conducted using streptozotocin-nicotinamide (STZ-NA) induced diabetic mice. Diabetic animals were orally administered the aqueous extract in 500 mg/kg of body weight to assess the antidiabetic effect. The blood glucose level and body weight of the experimental animals were monitored for 4 weeks. In addition, the histopathological examination of the treated mice pancreas was also conducted to observe the changes of β-cells during the treatment process. Results The extract produced a significant decrease in blood glucose level in diabetic mice. This decrease was equivalent to that which observed in mice treated with a standard after 2–4 weeks. In addition, the plant extract exhibited a potent inhibitory effect on α-amylase and α-glucosidase activity with IC50 values of 730.15±0.25 μg/mL and 94.81±5.99 μg/mL, respectively. Moreover, the histopathologic examination of the pancreas showed a restoration of normal pancreatic islet cell architecture which observed in the diabetic mice treated with plant extract. Conclusions The aqueous A. unedo roots extract has a significant in vitro and in vivo antidiabetic effects and improves metabolic alterations. The revealed results justify its traditional medicinal use.

The leaf latex of Aloe pulcherrima has been used as remedy for diabetes mellitus. This was carried out to determine in vitro and in vivo antidiabetic activities of the leaf latex of Aloe pulcherrima. Methods. Sucrase and maltase inhibitory activity of the leaf latex of A. pulcherrima was determined in glucose oxidase assay, and α-amylase inhibitory activity was determined in dinitrosalicylic acid assay. Normoglycemic, glucose-loaded, and streptozotocin-induced diabetic mice were treated orally to determine blood glucose lowering activity of the latex. Effect of the latex on serum lipid level and body weight was measured in streptozotocin-induced diabetic mice. Additionally, DPPH assay was used to determine free radical scavenging capacity of the latex. Results. Antioxidant activity of the latex was concentration dependent; the strongest inhibition was measured at 800 μg/ml (80.57%). The leaf latex of A. pulcherrima inhibited sucrase (IC50 = 2.92 μg/ml), maltase (IC50 = 11.81 μg/ml) and α-amylase (IC50 = 14.92 μg/ml) enzymes. All doses of the leaf latex induced hypoglycemic effect after 4 h in normal mice, and low dose of the latex did not show significant effect after 6 h. Glucose reduction of the leaf latex of A. pulcherrima was significant (p<0.05) in oral glucose-loaded mice compared to the vehicle control. Blood glucose level of diabetic mice was significantly (p<0.05) reduced on week one and weak two in a streptozotocin-induced diabetic mouse model. Glucose reduction increased with increasing the doses of the leaf latex of A. pulcherrima on week one (p<0.05 (200 mg/kg), p<0.01 (400 mg/kg), and p<0.001 (600 mg/kg)). Administration of the leaf latex of A. pulcherrima for two weeks significantly (p<0.05) improved diabetic dyslipidemia and body weight of diabetic mice. Conclusion. The study confirmed that the leaf latex of the plant showed a significant antidiabetic activity justifying the traditional uses of the plant.
