Diabetes Type 2 is the most common type of diabetes, a common disorder of glucose homeostasis and accounts for 90% of cases. The prevalence of diabetes type 2 is increasing. Adenosine deaminase is an enzymatic polymorphism that plays an important role in modulating the biological activity of insulin. It seems that excessive activity of the adenosine A1 receptor has caused adiposity in diabetes type 2. In this study, we examined the correlation of ADA enzyme with diabetes type 2. This investigation was performed on 80 men and women between 40 and 80 years old in District 2 of Tehran with diabetes. Venous blood samples were collected after 12 hours of fasting blood was centrifuged. Then fasting blood glucose and HbA1c, Triglyceride, and total Cholesterol were measured for enzyme activity respectively by COBAS MIRA. Insulin was measured by ELISA and serum ADA enzyme activity was measured by photometry. The results of this study were done by SPSS software. A significant increase in serum ADA levels was observed in diabetic patients compared with the control group. A positive correlation was observed between ADA activity and FBS and HbA1c. The amount of HOMA-IR in diabetics was higher than in the control group, but no positive correlation was observed between serum levels of ADA and HOMA-IR. The enzyme adenosine deaminase can act as an immunological marker and the results of this study show that diabetes is associated with increased T cell activation markers and immune disequilibrium. Serum ADA level has a positive correlation with glycemic control status in patients.

Hyperlipidemia is a major risk factor for the development of cardiovascular disease. In this study, the effects of an unripe fruit extract of Momordica charantia on total cholesterol, total triglyceride and lipoproteins in the blood of mice with hyperlipidemia were investigated. In this study, 28 adult male Wistar rats weighing 210 to 250 g were selected and randomly divided into four groups of seven. One group was on a normal diet and the other groups were fed a high-fat diet for 8 weeks to develop hyperlipidemia. Experimental groups in this study were included group 1: control, oral administration of normal food without any drugs or extracts. Group 2: hyperlipidemia mice, feeding with normal food. Group 3: hyperlipidemia mice with a diet containing 4%. Group 4: hyperlipidemia mice with a diet containing 8%. The animals were fed by gavage at a dose of 4% and 8% of M. charantia powder solution for 15 days. Blood samples were taken and the level of total cholesterol, total triglyceride, and high-density lipoproteins (HDL) were measured enzymatically. The amount of low-density lipoproteins was calculated by Friedewald's formula. Data were analyzed using the analysis of variance. Experimental results showed that immature fruit powder of M. charantia quarantine significantly reduced serum triglycerides in group 8% mice fed rats fed a high-fat diet. Moreover, immature fruit powder of M. charantia increased the level of high-density lipoproteins. There was a statistically significant difference between the level of cholesterol and the level of low-density proteins (LDL). The highest reduction belonged to the group receiving immature powder. The results of the experiment showed that the unripe fruit extract of M. charantia has strong antilipidemic effects on rats fed with a high-fat diet.
