Background: Adrenal gland is an important endocrine that secrets several hormones play a key role in the adaptation of newborn to extra uterine life. The study was conducted explore histomorphological development adrenal glands Gohilwadi Goat (Capra hircus). Methods: research work carried out on twenty pair goat collected from local abattoir. animals were divided into three age groups, viz. gro...

Mibefradil is a new cardiovascular drug with peculiar Ca++ antagonistic properties. The most remarkable feature of mibefradil is its unique relative selectivity for T type calcium channels, a property that has been proposed to explain in part the beneficial pharmacological and clinical profiles of this drug. In adrenal glomerulosa cells, aldosterone biosynthesis and secretion in response to ang...

Stereological studies were performed on 20 pairs of adrenal glands of human foetuses. The volume of particular adrenocortical zones, average cell volume and number of parenchymal cells were calculated. In 50 to 320 mm crown-rump length (C.-R.L.) foetuses (9-38 weeks of the intra-uterine life) an exponential increase in adrenal gland weight was found. If compared with the earlier period, the rat...

We examined the effect of EGF and angiotensin II (AII) on the formation of inositol phosphates and aldosterone secretion, and observed the role of tyrosine phosphorylation in EGF or AII-mediated aldosterone secretion. As cultured glomerulosa cells were incubated with increasing concentrations of EGF (0.01-100 ng/mL), aldosterone secretion increased and reached a plateau at EGF concentration of ...

Catnip (Nepeta cataria) is an important medicinal herb belonging to the mint family, Lamiaceae. In this study, the in vitro antimicrobial and antioxidant activities of the essential oil and methanol extract from Nepeta cataria, and its essential oil composition were investigated. The essential oil, which has 4aalpha,7alpha,7abeta-nepetalactone (70.4%), 4aalpha,7alpha,7abeta-nepetalactone (6.0%)...

The composition and antimicrobial activity of the essential oil of Nepeta crispa Willd., an endemic species from Iran, was studied. The oil was obtained from the aerial parts of the plant and analyzed by GC and GC/MS. Twenty-three compounds, accounting for 99.8% of the total oil, were identified. The main constituents were 1,8-cineol (47.9%) and 4aalpha,7alpha,7abetanepetalactone (20.3%). The a...

Angiotensin II (AngII) plays a crucial role in the control of aldosterone biosynthesis in adrenal glomerulosa cells through the stimulation of two distinct Ca2+ entry pathways: (1) opening of voltage-operated calcium channels, and (2) activation of a capacitative Ca2+ entry that is dependent on calcium release from intracellular pools. Adrenocorticotrophic hormone (ACTH), on the other hand, a m...

Nepeta species are widely used in folk medicine as a diaphoretic, diuretic, antiseptic, astringent, anti-asthmatic, cough suppressant, antispasmodic, antipyretic, sedative and stomachic. This study was designed to examine the chemical composition of essential oil isaurica sulfuriflora. It determined that aerial parts N. plant contained 0.72% oil, 37 compounds were identified representing 98.86%...

Angiotensin II is one of the main physiological regulators of aldosterone biosynthesis in the zona glomerulosa of the adrenal cortex. The hormone stimulates intracellular cholesterol mobilization to the mitochondrion for steroid biosynthesis. Here we have examined whether angiotensin II also modulates exogenous lipoprotein cholesterol ester supply to the steroidogenic machinery and whether this...
