INTRODUCTION plurihormonality of pituitary adenomas is an ability of adenoma cells to produce more than one hormone. After the immunohistochemical analysis had become a routine part of the morphological study, a great number of adenomas appeared to be multihormonal in actual practice. We hypothesize that the same cells of a normal pituitary gland releases several hormones simultaneously. OBJE...

OBJECTIVE To analyse the usefulness of plasma anti-mullerian hormone (AMH) measurement as a tool for assessing ovarian reserve in a general infertility population. MATERIALS AND METHODS Plasma AMH levels were analysed in 238 women aged 18-46 years during day 3-5 of their menstrual cycle. All 238 patients had follicle stimulating hormone (FSH) levels less than 10 i.u./L, suggesting normal ovar...

The research was intended for studying the association between follicular size and some hormonal ionic compounds fluid with oocyte development in ovaries of local goats (Capra hircus), period from September 2020 to March 2021 department Animal Production techniques at Al-Musaib Technical College. 150 genital organs were gathered adult non –pregnant female (does), which slaughtered Babylon provi...

Type 1 angiotensin II (ANG II) receptors play crucial roles in the regulation of blood pressure and fluid osmolarity, whereas the physiological roles of type 2 ANG II receptors (AT2) remain unclear. Because AT2 is expressed in atretic follicles where granulosa cells undergo apoptosis, we examined the space and time relationship between AT2 expression and follicle atresia in vivo and the effect ...

A 92-amino acid polypeptide, alpha-inhibin-92 (alpha-IB-92), has been isolated and characterized from human seminal plasma and found to be active in suppressing follicle-stimulating hormone (FSH) release in vitro. In the present in vivo study, intravenous injection of synthetic alpha-IB-92 (4 and 20 micrograms) significantly suppressed FSH release (P less than 0.001), whereas this peptide had n...
