Alteration by neonatal hypothyroidism of the critical period for the induction of persistent estrus in the rat.
نویسنده
چکیده
The effects of hypothyroidism for a short period of postnatal life on the induction of persistent estrus by androgen were investigated in female rats of 10 and 13 days of age. Hypothyroidal new born rats produced by feeding propyl thiouracil (PTU) to the mother rats, were more succeptible to the persistent-estrus inductive influence of androgen than normal and thyroxine-therapied hypothyroidal rats of the same age.It is concluded that the period during which androgen exerts a persistent-estrus inductive influence was prolonged in hypothyroidal rats, possibly as the result of the retardation of development of the hypothalamic region, the site affected primarily by androgen.

CGRP, which coexists with acetylcholine in trigeminal motoneurons, could be one of the regulatory anterograde factors responsible for the enhanced expression of AChR subunits in neuromuscular junction. It has been also shown that low level of thyroid hormone plasma concentration has influence on the transitional development of muscle fibers and related motoneurons through a sever reduction in A...

Introdution:Methyl paraben (MP) is an xsenoestrogen pollutant that is classified into preservatives due to its antibacterial properties. The aim of the present study was to investigate the effects of MP in female neonatal mice on puberty timing, estrus cycle, and ovarian follicle profile. Methods:In this experimental study, one-day-old Balb/c mice were randomly divided into 5 groups (n = 8), i...
متن کاملInhibitory effect of 5-hydroxytryptophane on the induction of persistent estrus by androgen in the rat.
Effects of monoamines or its precursors on the induction of persistent estrus by testosterone propionate (T.P.) were studied in Wistar strain female rats. Daily treatment with 5-hydroxytryptophane (5-HTP) for the first 10 days of life delayed the occurrence of persistent estrus in rats given T.P. at 4 days of age. The onset of persistent estrus occurred in this group of animals at 67.1+/-2.5 da...

Introduction: Appropriate thyroid hormone (TH) levels are essential during the critical period of brain development, which is associated with the growth of axons and dendrites and synapse formation. In rats, oral motor circuits begin to reach to their adult pattern around 3 weeks after birth, the period in which alteration from sucking to biting and chewing occurs (weaning time). Trigeminal ...
