ABSTRACT
Experimental diabetes was induced in albino rats by subtotal Pancreatectomy followed by glucose load. This caused a marked inhibition in the activity of the seminal vesicles. The administration of mono-amine oxidase inhibitor and T-Dopa caused a marked improvement in the adrenergic response of the seminal vesicles in diabetic rats. The results lead to the conclusion that diabetes impairs the neuro-muscular mechanism that regulates the function of the seminal vesicles

Experimental diabetes was induced in albino rats by subtotal Pancreatectomy followed by oral glucose load. This caused marked inhibition in the seminal vesicle activity as recorded by the response to epinephrine hydrochloride. Experimentally diabetic animals were treated with separate doses of male and female sex hormones. The seminal vesicle function of diabetic animals was restored to the normal by 89.37% by using the male sex hormone and by 4.28% when the female sex hormone was administered

Experimental diabetes caused a reduction in the activity of the seminal vesicle by 46.76% of the average normal control. An increment in the seminal vesicle activity of 4.72% was observed when normal animals were treated with both male and female sex hormones in combination. The administration of the same hormones to diabetic rats improved the activity of seminal vesicle by 112.15%. In the seminal vesicles, a synergistic action between androgens and estrogens on its activity has been proved

In vivo treatment with MAOI and in vitro incubation of isolated seminal vesicles with insulin caused an improvement in contractile responses by 56% in diabetic animals only. Prior L-Dopa administration and insulin incubation caused an improvement in the adrenergic response of isolated seminal vesicles in normal and diabetic rats. In the latter group, the improvement reached 41.21%. The observed improvement is due to the combined actions of either insulin and MAOI or insulin and L-Dopa

Monoamine Oxidase Inhibitors , Levodopa , Diabetes Mellitus, Experimental , InsulinABSTRACT
Pretreatment with sex hormones and incubation with insulin improved the adrenergic response of isolated seminal vesicles in both normal and diabetic animals. Improvement reached a value of 114.74% in normal animals and 67.01% in diabetic ones. It is clear that the administration of sex hormones had the strongest beneficial effect in diabetic animals since the increments in the seminal vesicle activity due to MAOI and L-Dopa were 56% and 41.21% respectively

Rats maintained on either constant illumination [LL] or constant dark [DD] were compared to those exposed to 14 hr dark Schedule [LD]. At the estrous phase, LL caused a reduction in LH level throughout the twelve weeks observation period. FSH levels were increased to a peak at the 8th week then decreased. Pituitary gland weight was significantly increased from the 8th week observation period onward with a histochemical presence of more FSH and LH producing cells. Ovarian and uterine weights were also increased with no evidence of ovulation histologically in the ovaries. Constant dark caused prolongation of the estrous cycle to 6-7 days in 96% of animals. At the estrous phase, LH level insignificantly increased throughout the observation period whereas FSH reached a peak maximum at the 8th week then decreased. No significant changes in pituitary, ovarian and uterine weight or cytology occured. This study demonstrates that the light-darw cycle as an environmental factor is profoundly affecting the reproductive cycle in female rats
