This 2007 study investigated the impact of chronic lithium administration on memory in rats. Over 30 days, rats received daily intraperitoneal injections of lithium chloride (2 mmol/kg) or saline. In T-maze alternation tasks, lithium-treated rats demonstrated significantly higher accuracy at 30- and 45-second delays compared to controls, indicating enhanced spatial
This study examined the effects of Ginkgo biloba extract on stress-induced biochemical changes in rats, specifically focusing on alterations in brain neurotransmitters and plasma corticosterone levels. The results showed that Ginkgo biloba supplementation normalized elevated levels of norepinephrine, dopamine, serotonin, and corticosterone induced by stress, suggesting its potential to counteract
This study investigated the neuroprotective effects of methylene blue (MB) in rats suffering from intracerebral hemorrhage (ICH). The findings showed that MB significantly improved neurological function, reduced brain swelling, and protected the blood-brain barrier. The neuroprotective effects were linked to a reduction in apoptosis and neuroinflammation via the PI3K/Akt/GSK3β signaling
This animal study investigated the effects of Melanotan-II (MT-II), a melanocortin receptor agonist, on penile erection in anesthetized rats. MT-II induced penile erections in a dose-dependent manner through intravenous, intrathecal, and intracavernous administration. Specifically, intravenous administration at a dose of 1 mg/kg increased the amplitude of erectile responses elicited by
