Nowadays the epidemiological burden of diabetes increases with long life-threatening symptoms and the eﬀects of antidiabetic drugs. Lack of insulin activity is one of the signs of a drop in diabetes mellitus. The mechanisms in antidiabetic include stimulating β-Langerhans cells which secrete insulin and inhibit enzyme activity. The purpose of this study was to analyze the eﬀect of giving tamarind leaf extract on levels of homa-β in type 2 diabetes mellitus rats. This study used 30 male Wistar rats aged 8-12 weeks with a bodyweight of 150-200 grams and separated into 5 groups. The first group is KN group (DMT2 mice + standard diet), group 2 is KP (DMT2 + Acarbose mice), group 3 is P1 (DMT2 mice + tamarind leaf extract 28 mg / 200gr / day), group 4 is P2 (rat DMT2 + tamarind leaf extract 56 mg/200gr/day), and group 5 is P3 (DMT2 rat + tamarind leaf extract 112 mg / 200gr / day). The measurement method for Homa-β is to use a standardized formula and use the results of blood tests for fasting blood glucose and insulin levels. The results of the inter-variable study using one-way Anova found a significant diﬀerence between the levels of homa-β and the administration of tamarind leaves extract in rats with type 2 diabetes mellitus model (p <0.05). There were significant diﬀerences in the 5 treatment groups. On the 7th day, there was an increase in homa-β levels in the KP, P1, P2, and P3 groups while in the KN group decreased in homa-β levels. The P3 group was seen to have the highest increase in homa-β levels in the 14th day, but on the 14th day there was no significant diﬀerence between the acarbose drug group (99.57 ± 6.41) and the P3 group (15.09 ± 1, 71). The conclusion was the administration of tamarind extract at a dose of 28.56, and 112 mg/kgBW/day significantly increased levels of HOMA-β for 7 and 14 days in rats with type 2 diabetes mellitus.

Vitamin D deficiency is now a recognised problem affecting multiple physiological functions. The aim of the present study was to evaluate the effect of a single dose of vitamin D3 injection on the inflammatory, muscular damage, metabolic and cardiovascular responses to an acute bout of resistance exercise (RE) in vitamin D-deficient resistance-trained males. Blood samples from fourteen vitamin D-deficient resistance-trained males were obtained during two separate trials: lower vitamin D (LVD) and higher vitamin D (HVD, after vitamin D3 injection). Metabolic, inflammatory, muscle damage and cardiovascular markers were evaluated at baseline, immediately and 1 h after RE. There were significant trial-by-time interactions for insulin and homeostatic model assessment of insulin resistance (HOMA-IR) which significantly (P < 0·05) declined for 1 h after RE in the HVD trial compared with the LVD trial. Homeostasis model assessment of β-cell function (HOMA-β) declines at 1 h post-RE in the HVD trial. There was also a time effect for blood sugar which significantly (P < 0·05) decreased and for creatine kinase, lactate dehydrogenase and IL-6 which increased significantly 1 h post-RE in both trials. There were no significant changes in other inflammatory and cardiovascular markers following both trials. A single injection of vitamin D3 improved insulin resistance and β-cell function following RE in previously vitamin D-deficient resistance-trained males. Conversely, the injection did not change muscle damage and the inflammatory response to acute RE. Intramuscular vitamin D replacement may have key implications for the promotion of glucose metabolism and lowering the risk of diabetes in vitamin D-deficient individuals.

To evaluate the predictive accuracy of surrogate measures of fasting insulin resistance/sensitivity like the Homeostasis model assessment for insulin resistance (HOMA –IR), Fasting glucose/insulin ratio (FG-IR), Quantitative insulin sensitivity check index (QUICKI), and the 20/fasting C peptide x fasting plasma glucose [20/(FCP × FPG)] index in comparison to M value derived from hyperinsulinaemic-euglycaemic clamp (HEC) studies in two birth weight based cohorts of Asian Indian males.
