A quantitative histological study of adrenal development during the perinatal period in intact and hypophysectomized pigs.

A quantitative histological study of adrenal development during late gestation and the perinatal period in intact and hypophysectomized fetal sheep.

Growth of the sheep adrenal was studied during late gestation and the perinatal period. Adrenals were recovered from 28 fetuses taken at D100 (D0: day of mating), D120, D132 and D144, and in 4 newborn animals 3 days after birth (equivalent to D151). Animals were of the Ile de France breed. Cortex (without capsule) and medulla volumes increased respectively by 7.2 and 2.4 between D100 and D151. ...

Exposure to cell phone radiofrequency changes corticotrophin hormone levels and histology of the brain and adrenal glands in male Wistar rat

Objective(s): Nowadays, the electromagnetic field-emitting devices are used routinely in our lives. Controversial reports exist concerning the effects of mobile radiofrequency (RF) on different parts of the body, especially stress hormones. The main goal of the present work was to study the long-term effects of mobile RF900 MHz exposure with special focus on the adrenal gland pathophysiology an...

The regulation of glucocorticosteroid secretion during the perinatal period.

The regulation of adrenal activity during the perinatal period raises different experimental problems; studies are often limited and their conclusions vary with the species studied. During the perinatal period, the profile of the ratio of adrenal weight to body weight reaches a minimum earlier the more mature is the species; this minimum occurs before birth in sheep, at birth in guinea-pigs and...

Histological and histometrical study of common carp ovarian development during breeding season in Khouzestan province in Iran

This survey was aimed at detecting histological and histometrical changes of Common Carp ovaries in Khouzestan Province climate conditions. The goal was to determine the ovarian status in the breeding period of the reproductive cycle. Ovaries of 49 Common Carp brooders were collected from April to October, 2010. The samples were taken from the anterior, median and posterior portions. 5-6µ secti...
