Effects of several conditions known to stimulate the zona glomerulosa of the adrenal cortex in the adult were examined on the fetal adrenal cortex of rats histochemically and electron microscopically. The stimulating conditions were the following; administration of Na restricted diet to the mother, administration of KCl or angiotensin II to the fetus, spironolactone or insulin to the mother. In...

The present study has been to test the effect of hydrocortisone (HC) on the mitotic incidence in adrenocortical cells of organ-cultured rat adrenal explants during a 24-hour incubation with or without angiotensin II (ANG). It was shown that HC significantly decreased the mean mitotic activity rate (MMAR) of adrenocortical cells in organ culture. That decrease concerned all the three cortical zo...
An investigation of the biological effect of catnip oil (Nepeta cataria L.) on the behavioral response of field collected Aedes aegypti and Anopheles harrisoni was conducted using an automated excitorepellency test system. Aedes aegypti showed significantly higher escape rates from the contact chamber at 5% catnip oil compared to other concentrations (P < 0.05). With Anopheles harrisoni, a high...
A comparison of the effects of adrenocorticotropic hormone (ACTH) on the cholesterol side chain cleavage system of zona glomerulosa and zona fasciculata-reticularis tissue of the rat adrenal is presented. Following hypophysectomy, the rate of pregnenolone formation from endogenous cholesterol in mitochondria from zona fasciculata-reticularis was lower than in mitochondria from zona glomerulosa....
Adrenic acid (docosatetraenoic acid), an abundant fatty acid in the adrenal gland, is identical to arachidonic acid except for 2 additional carbons on the carboxyl end. Adrenic acid is metabolized by cyclooxygenases, cytochrome P450s, and lipoxygenases; however, little is known regarding the role of adrenic acid and its metabolites in vascular tone. Because of its abundance in the adrenal gland...
A quantitative analysis of zone-specific proliferation was done to determine the recovery of adrenal cortical zonation during regeneration after enucleation. Adult male rats underwent adrenal enucleation [unilateral enucleation (ULE)] or sham surgery, both accompanied by contralateral adrenalectomy. At 2, 5, 10, and 28 days, blood and adrenals were collected to assess functional recovery. Adren...
Integrins are responsible for adhesion and activation of several intracellular cascades. The present study was aimed at determining whether the interaction between fibronectin and integrins could generate pathways involved in physiological functions of rat adrenal glomerulosa cells. Immunofluorescence studies and adhesion assays showed that fibronectin was the best matrix in promoting the forma...
The adrenal gland of the rat is continuously regenerated through proliferation of a stem cell population in the outer part of the gland. To clarify the location of proliferative events within the adrenal gland, and the factors that stimulate them, rat adrenal capsule preparations, consisting of capsule, zona glomerulosa (ZG) and the outer zona fasciculata (ZF) were maintained in vitro under dif...
