Effect of Tilia platyphyllos L. Extract on the Sex Hormones Levels and Histopathology Index in Varicocele-Induced Infertile Rats

Type 2 diabetes is the most common endocrine disease that can cause damage and cell death or apoptosis. The aim of this study was to investigate the expression of apoptotic and anti-apoptotic gene of heart tissue and insulin resistance index after intense intermittent exercise and consumption of thyme honey in diabetic type 2 rats.

The statistical population consisted of rats. After 20 weeks of high fat diet and injection of STZ became diabetic. Rats in 4 groups: control(n=6),HIIT(n= 8),thyme honey(n= 6),HIIT-thyme honey (n=8) trained HIIT for eight weeks, five sessions per week with intense 2-minute intense alternation with 2 to 8 alternations and with 80 to 90% vo2max and one-minute rest alternation with 50 to 56% vo2max.Thyme honey was given by gavage at a rate of 3g/kg 5days a week. Glucose, insulin and expression of Bax and Bcl2 genes and their ratio was calculated. Statistical analysis was performed using two-factor analysis of variance test and determining the effect size and Bonfroni post hoc.

HIIT and thyme honey decreased Bax gene expression and increased Bcl2 expression in heart cells (P<0.05). HIIT and thyme honey in diabetic rats led to improved glucose and insulin levels and decreased insulin resistance index. It also decreased the expression of Bax gene and increased the expression of Bcl2 (P<0.05).

HIIT with thyme honey led to improved glycemic profile and changes in glucose and insulin levels, as well as positive and appropriate changes in the expression of cardiac and anti-apoptotic genes.
