Abstract
Background: Cholestasis is a multifaceted disease that influences not only the function of the liver but also affects many other organs. In this context, cholestasis-induced lung injury is a significant clinical complication. Unfortunately, there is no precise therapeutic option against cholestasis-associated lung injury. It has been revealed that oxidative stress and inflammatory response play a role in cholestasis-induced pulmonary damage. Sildenafil is a phosphodiesterase enzyme inhibitor used in the management of erectile dysfunction. Meanwhile, several experiments revealed the effects of sildenafil on oxidative stress and inflammation. This study aimed to evaluate the effect of sildenafil on cholestasis-induced oxidative stress and inflammation in cholestasis-induced lung injury. Methods: Rats underwent bile duct ligation (BDL) to induce cholestasis. Bronchoalveolar lavage fluid (BALF) levels of inflammatory cells, cytokine, and immunoglobulin were monitored at (3, 7, and 14 days after BDL surgery). Moreover, lung tissue histopathological alterations and biomarkers of oxidative stress were evaluated. Results: A significant increase in BALF inflammatory cells, TNF-α, and immunoglobulin G (IgG) was evident in BDL animals. Moreover, the infiltration of inflammatory cells, vascular congestion, and hemorrhage were detected in the lung of BDL rats. Increased markers of oxidative stress were also evident in the lung of BDL animals. Sildenafil (10 and 20 mg/kg) significantly blunted inflammatory response, oxidative stress, and histopathological alterations in the lung of cholestatic animals. Conclusion: The effects of sildenafil on inflammatory response and oxidative stress biomarkers seems to play a crucial role in its protective properties in the lung of cholestatic animals.

Glycine protects the male reproductive system against lead toxicity via alleviating oxidative stress, preventing sperm mitochondrial impairment, improving kinematics of sperm, and blunting the downregulation of enzymes involved in the steroidogenesis.

Abstract
Lead (Pb) is a highly toxic heavy metal widely dispersed in the environment because of human industrial activities. Many studies revealed that Pb could adversely affect several organs, including the male reproductive system. Pb-induced reproductive toxicity could lead to infertility. Thus, finding safe and clinically applicable protective agents against this complication is important. It has been found that oxidative stress plays a fundamental role in the pathogenesis of Pb-induced reprotoxicity. Glycine is the simplest amino acid with a wide range of pharmacological activities. It has been found that glycine could attenuate oxidative stress and mitochondrial impairment in various experimental models. The current study was designed to evaluate the role of glycine in Pb-induced reproductive toxicity in male mice. Male BALB/c mice received Pb (20 mg/kg/day; gavage; 35 consecutive days) and treated with glycine (250 and 500 mg/kg/day; gavage; 35 consecutive days). Then, reproductive system weight indices, biomarkers of oxidative stress in the testis and isolated sperm, sperm kinetic, sperm mitochondrial indices, and testis histopathological alterations were monitored. A significant change in testis, epididymis, and Vas deferens weight was evident in Pb-treated animals. Markers of oxidative stress were also significantly increased in the testis and isolated sperm of the Pb-treated group. A significant disruption in sperm kinetic was also evident when mice received Pb. Moreover, Pb exposure caused significant deterioration in sperm mitochondrial indices. Tubular injury, tubular desquamation, and decreased spermatogenic index were histopathological alterations detected in Pb-treated mice. It was found that glycine significantly blunted oxidative stress markers in testis and sperm, improved sperm mitochondrial parameters, causing considerable higher velocity-related indices (VSL, VCL, and VAP) and percentages of progressively motile sperm, and decreased testis histopathological changes in Pb-exposed animals. These data suggest glycine as a potential protective agent against Pb-induced reproductive toxicity. The effects of glycine on oxidative stress markers and mitochondrial function play a key role in its protective mechanism.
