Background: Very limited data are available regarding the association of vitamin D with glycemic status among adults with newly detected type 2 diabetes mellitus (T2DM) in Bangladesh. Objectives: To determine vitamin D status and its association with glycemic status in Bangladeshi adults with newly detected T2DM. Materials and Methods: This cross-sectional study was carried out in 102 newly detected T2DM diagnosed on the basis of the American Diabetes Association 2017 criteria (age: 42.95 ± 10.68 yrs.;m/f: 44/58) and equal number of age and sex matched controls (age: 40.43 ± 11.04 years) recruited consecutively from the Department of Endocrinology, BSMMU to measure serum vitamin D by high performance liquid chromatography method. Results: Both vitamin D deficiency (p p p 1c (r = -0.249, p = 0.011) in patients with T2DM. HbA1c was linearly associated with vitamin D (β = -0.26, p = 0.009) and severe vitamin D deficiency by binary (OR = 1.37, p = 0.003) and multinomial logistic regression (HbA1c ≥ 10%: OR = 4.25, p = 0.04) in people with T2DM after adjustment for age and BMI.

Visceral adiposity mediates insulin resistance, but their association among adults with prediabetes is scarce in the literature. This study is aimed to determine the association of visceral adiposity index (VAI) with insulin resistance in adults with prediabetes. This cross-sectional study was done among 117 adults with newly detected prediabetes [m/f;23/94;mean ± SD: Age 36.30 ± 9.99 years, BMI 28.89 ± 4.35 kg/m2] based on American Diabetes Association 2018 criteria and 141 matched healthy controls [m/f: 28/113;mean ± SD: 35.30 ± 6.88 years, BMI 25.03 ± 4.58]. Waist circumference, body mass index, fasting triglyceride, HDL cholesterol, fasting blood glucose and insulin were measured in each group to calculate VAI and homeostatic model assessment of insulin resistance (HOMA-IR). People with prediabetes had significantly higher median value of VAI {3.08 (2.26) vs. 1.86 (2.31);p 1) (98.3% vs. 85.8%;p

Trachysperum ammi has been traditionally used for the treatment of neurological disorders such as depression and anxiety. To date, T. ammi has reported for its chemical constituents in different diseases condition. The traditional evidence convinced us to perform the antidepressant-like activity of methanolic extract of Trachysperum ammi (META). The antidepressant activity of META assessed by using forced swimming test (FST), tail suspension test (TST), and locomotor activity test. The seed parts of META at doses level of 50, 100 and 200 mg/kg body weight administered orally to examine the CNS stimulants activity test in mice behavioral models. Here, we reported that META significantly reduced immobility time in the FST after repeated administration of 50, 100 and 200 mg/kg to mice for 14 days. The intensity of immobility significantly reduced at all of the doses (p < 0.05) whereas, we were found the strongest effect observed at 200 mg/kg. The antidepressant-like effect of META caused the reduction (p < 0.05) in the immobility in TST of mice when orally administered with 50, 100 and 200 mg/kg for 14 days, respectively. Additionally, we were executed locomotor activity test to check the motor stimulating activity. META has employed at a dosage of 50, 100 and 200 mg/kg for 14 days, the results have found that 50 mg/kg produced the locomotion effects as similar to the control group. Interestingly, the locomotion, rearing, and defecation significantly (p < 0.05) increased at the dosage of 100 and 200 mg/kg of META. Our present findings suggest that the seed parts of Trachysperum ammi may possess antidepressant-like activity which may use as a supportive treatment to management of neurological disorders.

Background: Thunbergia erecta (Acanthaceae) is the most abundant medicinal plant in different parts of Bangladesh where it is known as “nilghonta”. It has been used as traditional medicine for insomnia, depression and anxiety management. However, no scientific evidence of T. erecta belonging to neuropharmacological activity has been reported. The aim of present study was to investigate in vivo sedative and anxiolytic activities of methanol extract from the leaves of T. erecta in Swiss Albino mice. Methods: Sedative activity of METE was investigated using open field, hole cross and thiopental sodium-induced sleeping time test model whereas anxiolytic activity was screened by elevated-plus maze, light-dark box, hole-board and marble-burying test method in mice at 200 and 400 mg/kg doses. The acute toxicity study and phytochemical analysis of METE also carried out. Diazepam used as the positive control for the following behavioral pharmacology test. Results: METE exhibited significant (p Conclusion: The experimental result indicates T. erecta contains phytoconstituents that possess sedative and anxiolytic activity which traditionally used in insomnia, depression and anxiety management.
