The protective effect of angiotensin II type I receptor blocker (valsartan) on behavioral impairment, NLRP3, BDNF, and oxidative stress in the brain tissue of ovariectomized female rats.

Depression and anxiety are common mental health disorders affecting thoughts, behaviors, and emotions. This study aimed to investigate the effect of the angiotensin II type I receptor blocker (AT1RB), valsartan, on menopause-induced depression and anxiety-like behaviors, and to elucidate possible mechanisms of action by measuring levels of nod-like receptor protein 3 (NLRP3), interleukin-1beta (IL-1β), brain-derived neurotrophic factor (BDNF), and oxidative stress in brain tissue. Thirty-two Wistar albino female rats were randomly divided into four groups (n = 8 per group): Control, AT1RB, OVX, and AT1RB + OVX.

Protective effect of metformin against ovariectomy induced depressive- and anxiety-like behaviours in rats: role of oxidative stress.

Several studies have shown that low estrogen levels can lead to an increase in the incidence of depression and anxiety during menopause. The hippocampus and prefrontal cortex are parts of the brain involved in depressive- and anxiety-like behaviors. Recent studies have revealed that metformin has neuroprotective effects mainly due to its antioxidant properties.

The effect of an antifibrotic agent, pirfenidone, on penile erectile function in an experimental rat model of ischemic priapism.

To date, no effective medical approach for the treatment of erectile dysfunction (ED) secondary to ischemic priapism (IP) has been described. The aim of this study was to evaluate the anti-inflammatory, antifibrotic, and antioxidant effects of pirfenidone (PFD) on cavernosal tissue in a rat model of IP. Forty-eight male albino rats aged 8-10 months, with mean weights of 410 ± 18.
