  • Effects of Cinnamon on Blood Glucose Level and Lipid Profile in Syrian Type 2 Diabetes Patients

    Diabetes mellitus (DM) is one of the most common metabolic disorders that causes micro- and macro-vascular complication. The aim of this study was to evaluate The effects of cinnamon on fasting blood glucose (FBG), triglyceride (TG), total cholesterol (TC), and low density lipoprotein (LDL) in Syrian individuals with type 2 diabetes mellitus (T2DM). A total of 90 patients with type 2 diabetes (T2D), were randomized into two groups: one for placebo and one for treatment with cinnamon powder (Cinnamomum cassia), in daily amounts of 2 grams. We measured the patients’ blood glucose and lipid levels under fasting conditions at the beginning of the study, and again at 30 days, the end of treatment. The mean value of FBG level on the starting day before cinnamon intake was found to be 176.8 ± 9.6 mg/dl, and the mean values for lipids were TG 183.5 ± 15.5 mg/dl, TC 209.4 ± 7.8 mg/dl and LDL 119.4 ± 5.8 mg/dl. When diabetic patients were treated with the dose of 2 g cinnamon for 30 days, their mean FBG level dropped to 147.4 ± 8.9 mg/dl, TG 135.7 ± 9.6 mg/dl, TC 149.3 ± 8.6 mg/dl and LDL to 74 ± 6.2 mg/dl. No significant changes were noted in the placebo groups. The results of this study indicate that intake of 2 grams of cinnamon per day reduces serum glucose, TG, TC, and LDL and thus reducing the risk of diabetic complications.

  • Intrinsic activity of aqueous leaf extract of Cymbopogon citratus against plasmodium-mediated tropical disease

    Objective: To investigate the intrinsic activity (efficacy) of aqueous leaf extract of Cymbopogon (C.) citratus against malaria, a plasmodium-mediated tropical disease. Materials and Methods: Plasmodium (P.) falciparum culture samples from 20 symptomatic adult outpatients were subjected to the antimalarial in vitro test. Parasite quantification by optical microscopy in the performance of in vitro antiplasmodial assays was employed. Roswell Park Memorial Institute (RPMI) 1640 was used as culture medium for cultivation of P. falciparum. Negative control was culture medium with the malarial parasites while treated drug was the leaf extract of C. citratus dissolved in dimethylsulphoxide (DMSO) and prepared into 7 levels concentration (3.125, 6.25, 12.5, 25, 50, 100 and 200 mg/mL.) After culture synchronized with sorbitol 5%, micromalarial culture were divided into control and treated groups then incubated in CO2 candle jar at 370C for 72 h. Each 8 h, the percentage of parasitemia were measured giving the activity of the extract on the growth stages of P. falciparum. Parasitemia was estimated by making the thin blood smear from the erythrocytes layer and stained with Giemsa (10%) for 30 mins. Using probit analysis, the antimlarial activity of the extract was calculated by counting the fifty percent of growth inhibition 50 (IC50). Results: The extract inhibited the growth of P. falciparum on mature schizont stage. The fifty percent inhibitory concentration (IC50) of the extract was 3.9 after 32 h incubation. Conclusion: The leaf extract of C. citratus has efficacious antimalarial effect against P. falciparum in vitro.

  • Effects of Myrica esculenta Bark Extracts on Melanin Biosynthesis

    In this study, we investigated the effect of crude extracts, derived from stem bark of Myrica esculenta on melanin production in mouse B16 melanoma cells. In response to a-melanocyte stimulating hormone (a-MSH), B16 melanoma cells underwent differentiation characterized by increased melanin biosynthesis. Treatment of Myrica esculenta bark extracts significantly blocked a-MSH-induced melanogenesis in a dose-dependent manner. a-MSH stimulated the activity of tyrosinase, a key melanogenic enzyme in melanin biosynthesis, which was significantly reduced by Myrica esculenta bark extracts. In addition, treatment of B16 melanoma cells with Myrica esculenta bark extracts decreased the protein expression level of tyrosinase. These results demonstrated that the inhibitory effects of Myrica esculenta bark extracts on melanogenesis may be due to the suppression of tyrosinase protein levels.
