Male Reproductive Injury is Blocked by Baicalin by Modulating Oxidative Stress and Apoptosis in Asthmatic Mice / 中国生物化学与分子生物学报

ABSTRACT

Reproductive health is an important issue in the field of population and health. As the most common respiratory disease in the world, asthma is linked with male reproductive dysfunction, but the related study is rarely reported. In this study, we analyzed the interventional effect of baicalin (BA) on male reproductive injury in asthmatic mice and its mechanism. Male BALB/c mice were randomly divided into three groups, namely as control group ( CK group), OVA-induced asthma model group ( OVA group) and baicalin intervention asthma group (OVA+BA group). The results showed that no significant difference was found in body weight among the three groups. In the OVA group, the testicular coefficient and sperm count decreased significantly, with sperm malformation rate increased significantly ( P < 0.05). In the baicalin intervention group, the testicular coefficient was increased significantly and sperm malformation rate decreased significantly ( P < 0. 05) ; Hematoxylin-eosin ( HE) staining showed that damaged basement membrane of seminiferous tubules, decreased the number of spermatogenic cells and reduced Johnson score were observed in OVA group. The seminiferous tubule diameter and seminiferous epithelium height were significantly increased (P < 0. 05), the basement membrane of seminiferous tubules was relatively complete and Johnson score gains in the OVA + BA group. Compared with control group, the contents of hydrogen peroxide ( H
