ABSTRACT
 Intracranial pathologies can affect pituitary hormone levels whether they are primarily related to the gland or not. In deficiencies, size and location of may be normal, as well one more effects observed after hypoplasia, partial empty sella, ectopic neurohypophysis, Rathke's cleft cyst, adenomas other masses surgeries. early puberty, dimensions usually increased, rarely hypoplas...

This study used mouse models to investigate the role of LIM homeodomain transcription factor Isl1 in pituitary development. It reveals that has multiple, critical roles gland Pituitary-specific deletion caused hypopituitarism with increased stem cell apoptosis, reduced both differentiation thyrotropes and gonadotropes body size, even promoted development multiple Rathke’s cleft-like cysts.

This study explored the effects of GnRH agonist (GnRHa) immunity on expression of FSHR mRNA in pituitary and FSHR protein in uteri, and also confirmed its efficacy on uterine development. 42 prepuberty and non cyclic ewes were assigned to 6 experimental groups (EG) during anestrus season. Animals in EG-I, EG-II and EG-III were subcutaneously injected with 200, 300 and 400 μg alarelin antigens (...

Pituitary tumours are common in dogs and being increasingly recognized cats. usually classified as adenomas should only be carcinomas when there is evidence of metastatic spread the tumour, which rare. Despite benign nature most pituitary tumours, they can still compress or invade neighbouring tissues. functional (hormonally active) non-functional silent). The aim this review was to provide an ...

the hypothalamo-pituitary-adrenocortical (hpa) axis is a critical adaptive system that maximizes survival potential in the face of physical or psychological challenge. the principal end products of the hpa axis, glucocorticoid hormones, act on multiple organ systems, including the brain, to maintain homeostatic balance. the brain is a target of stress, and the hippocampus is the first brain reg...

Panhypopituitarism occurs as a result of the insufficiency all hormones produced in anterior pituitary gland. Pituitary Stalk Interruption Syndrome (PSIS) is rare congenital syndrome leading to hypopituitarism. The should be evaluated patients with signs and symptoms hormone magnetic resonance imaging performed for etiology. Although PSIS cause hypopituitarism, it must treated replacement insuf...

Introduction: The endoscopic transsphenoidal approach for pituitary adenomas and other sellar lesions is quickly becoming the procedure of choice in their surgical management. The most common approach is binostril three-hand technique which requires a large exposure and subjects both nasal cavities to potential trauma. To reduce nasal morbidity, we employ a mononostril two-hand technique with t...

the main objective of this study was assessment of hormonal treatments effects on sperm quality improvement in barbus sharpeyi. results showed differences in effects of treatments with lhrha2, lhrha2 combined with a dopamine antagonist (met), and cpe (carp pituitary extract) on parameters of sperm volume, motility, spermatocrit, biochemical indices of seminal plasma and sperm efficiency on arti...

aflatoxins (afs) are natural contaminants of feed and feedstuffs, thus the study of the noxious effects ofthese agents on the male reproductive system is of outstanding importance. our aim for this study is theevaluation of the effects of oral administration of aflatoxin b1 on the reproductive hormonal changes in adult male rat. twenty eight wistar strain male rats were selected for this study....

The pituitary gland, also known as hypophysis, is a small pea-sized gland about 1 cm in diameter and 0.5 to 1 gram in weight. The pituitary gland resides in a small bony cavity situated at the base of the brain, known as sella turcica, and a pituitary stalk (infundibulum) maintains a connection between the pituitary gland and hypothalamus. The secretion of hormones by the pituitary gland is und...
