Exploring blood pressure dynamics and oxidative stress markers in an animal model of polycystic ovary syndrome.

Abstract

Background: Polycystic ovary syndrome (PCOS) is a hormonal disorder characterized by elevated androgen levels, heightened insulin secretion, and dysregulation of luteinizing hormone and follicle-stimulating hormone. This disorder results in metabolic disruptions, while the irregular estrous cycles associated with PCOS impact cellular functions like growth, movement, and alterations in cell adhesion within the tissue matrix.

Aim: This study aims to identify the blood tension, serum malondialdehyde (MDA) levels, and serum Metalloproteinase-1 (MMP-1) in rat models of PCOS. The study was conducted using female Wistar rats aged 6 months weighing between 130 and 180 g.

Methods: The rats were divided into three treatment groups: negative control, induction of testosterone propionate (TP) at a dose of 100 mg/kg BW IP for 12 days, and induction of estradiol valerate (EV) at a dose of 2 mg/kg BW IP for 2 days. Data were analyzed quantitatively using a one-way analysis of variance followed by a Posthoc Test using the least significant difference with a confidence level of 95%.

Results: The research results indicate that the average blood pressure of TP Group and EV Group did not differ significantly from the negative control (p > 0.05). Serum MDA levels were significantly different in the TP Group compared to the negative control (p < 0.05). On the other hand, MMP-1 levels showed no significant difference (p > 0.05) among all the treatment groups.

Conclusion: The findings of this study suggest that TP induction in a rat model of PCOS can potentially contribute to oxidative stress and lipid peroxidation, but does not significantly affect blood pressure or serum MMP-1 levels.
