描述

TEM photomicrographs of resveratrol-, metformin-, and combination-treated rat ovarian tissue show improved ultrastructural features compared to untreated PCOS. Mitochondrial morphology and endoplasmic reticulum integrity are partially restored.

Histopathological analysis of ovarian sections across control and experimental groups shows characteristic PCOS features including multiple cystic follicles and thickened theca cell layers. Treatment groups demonstrate partial normalization of ovarian morphology.

SIRT1 immunoreactivity in ovarian tissue varies across experimental groups, with reduced expression in PCOS rats and partial restoration following resveratrol and metformin treatment. SIRT1 is implicated in cellular stress responses and metabolic regulation.

AMPK immunoreactivity analysis reveals decreased phosphorylated AMPK in PCOS ovarian tissue compared to controls. Both metformin and resveratrol treatments partially restore AMPK activation, consistent with their known metabolic signaling effects.

TUNEL analysis of granulosa and theca cells quantifies apoptotic rates across experimental groups. PCOS induction increases apoptosis in granulosa cells, while resveratrol and metformin treatments reduce apoptotic indices toward control levels.

Transmission electron microscopy photomicrographs reveal ultrastructural details of oocytes, granulosa cells, and theca cells in control and PCOS groups. PCOS follicles exhibit mitochondrial swelling, dilated endoplasmic reticulum, and other signs of cellular stress.
