Abstract
Polycystic ovary (PCO) is a condition in which the secretion of specific hormones is disrupted. The adrenal glands are essential for the manufacture of certain hormones and the monitoring of steroid concentration, and they may be impacted in PCO situations. In a PCO-induced rat model, the researcher was aimed to investigate how administering exogenous estrogen, estradiol valerate affected on adrenal gland secretions and histology. The effects of Matricaria chamomilla flowers extract, and metformin will also be evaluated. 24 rats were divided into four equal groups: 1- control group, 2- PCO group, 3- metformin group, 4- Matricaria chamomilla group. PCO was induced by injecting 2 doses of estradiol valerate. The findings revealed a considerable increase in estrogen and ACTH levels in the PCO rats. The concentrations of cortisol and aldosterone were likewise higher in the PCO rats. These findings were corroborated by histological investigation of adrenal sections (both H&E and PCNA staining). Matricaria chamomilla flowers extract reduced all the hormonal alterations linked to PCO, including estrogen, ACTH, cortisol, and aldosterone. Metformin similarly reduced estrogen and ACTH. On the other hand, Metformin did not affect the hormonal changes associated with this model in terms of adrenal gland hormones (cortisol and aldosterone). In conclusion both treatments are improved that the histological investigation of adrenal secretions (both H&E and PCNA staining). The antiestrogen activity of Matricaria chamomilla could clarify that all the hormonal modulation occurs in this PCO model.
