Abstract:
Objective: To evaluate the plasma H2S levels and H2S synthesis activity in streptozotocin induced type 2 diabetes rats compared to the healthy controls and also to observe the effect of the aqueous extract of Swietenia macrophylla (S. macrophylla) seeds on the experimental groups. Methods: Seeds of S. macrophylla were separated, washed, shed-dried and finally extract was prepared. Thirty two wistar rats were selected for the experimental study. Streptozotocin was used for the induction of diabetes. H2S concentration in plasma was measured. H2S synthesizing activity in plasma was measured. Statistical analysis have done using Microsoft excel, Office 2003. Values were expressed by mean±SD. P<0.05 were considered statistically significant.Results:rats. The glucose levels are significantly lowered in the rats treated with metformin (5.48±0.03) mmol/L as well as with aqueous extract of S. macrophylla seeds (3.72±0.04) mmol/L. The HbA1c percentages in different groups of study subjects also indicate similar trends. Our study shows both the plasma H2S levels (22.07±0.73) mmol/L and plasma H2S synthesis activity (0.411±0.005 mmol/100 g) are significantly reduced in the streptozotocin induced diabetic rats.Conclusions:Although considering a small sample size, it can conclude that the fasting blood Fasting blood glucose level (7.74±0.02) mmol/L was significantly increased in diabetic glucose levels are inversely related to plasma H2S levels as well as H2S synthesis activity in plasma and the extract of S. macrophylla is associated with increased plasma H2S levels with effective lowering of blood glucose in streptozotocin induced diabetic rats.
