Stress-induced changes in the aged-rat adrenal cortex. Histological and histomorphometric study

Abstract: Histological alterations occurred in the adrenal cortex in response to stress, especially when coupled with the advancement of age. This was accompanied by increase in the area percent of collagen fibers and increase in the mean number of the proliferating cells in the adrenal cortex.

“…In accordance with our results, Ulrich-Lai et al ( 2006) demonstrated increased positive Ki67 cells in the outer ZF as a marker for increased cell division and hyperplasia in an animal model of chronic variable stress which possess many behavioral and biochemical characteristics similar to human depression. Also, Zaki et al (2018) explained the increase in the proliferating cells in the adrenal cortex of adult and senile stressed rats as the cellular turnover in the adrenal cortex occurs only to accommodate the physiological needs. Some researchers considered that the increase in adrenal weight is a better general indicator of stress than circulating corticosteroids (Creasy et al, 2013).…”

“…Вплив вищезгаданого фактора супроводжується комплексом неспецифічних змін в усіх органах організму, і також може бути причиною виникнення захворювань серцево-судинної, ендокринної систем та інших патологій [6]. Оскільки надниркові залози є стрес-чутливим органом у системі ендокринної регуляції усіх функцій організму, то за їх морфологічним станом можна характеризувати розвиток адаптаційних механізмів в умовах дії фактора стресу [7][8][9]. Разом з тим, захворювання щитоподібної залози, пов'язані зі стійкою нестачею гормонів унаслідок вродженого гіпотиреозу та інших тиреоїдних патологій, є причиною порушення гомеостазу, обміну речовин та кисню.…”

“…All the histomorphometric parameters, including the number of foci of myocyte disarray, the percentage area of collagen fibers in Masson Trichrome-stained sections, the percentage area of VEGF, caspase 3 immunoreactivity. and the count of CD31 immunohistochemically positive blood capillaries were estimated via the Leica Imaging analyzer software system (Leica Qwin 500C; Leica, Cambridge, England) 27 with a standard measuring frame of 85 550 mm 28 in 10 randomly selected, nonoverlapping fields from each animal in the different study groups.…”
