Abstract

To investigate the effects of Qiangjing Tablets (QJT) on sperm quality and the MAPK signaling pathway in the SD rat model of asthenospermia (AS). A total of 100 male SD rats were randomly divided into five groups of equal number, blank control, AS model control, high-dose QJT, medium-dose QJT, and low-dose QJT. All the rats were intragastrically administered ORN at 200 mg/kg/d for establishment of the AS model except those in the blank control group, which were given 1% CMC sodium solution at 1 ml/100 g by gavage. Meanwhile the animals of the high-, medium-, and low-dose QJT groups were gavaged with QJT at 6700, 3300 and 1700 mg/kg/d, respectively, qd 6 days a week for 20 days. Then the testis issue and the apoptosis of the testicular cells were observed under the electron microscope, the expression of vimentin in the testis was determined with the immunohistochemical SP method, that of ERK1/2 detected by Western blot, and the concentration of TGF-β1 in the semen measured by ELISA. The AS model controls showed round nuclei of spermatocytes, homogeneously distributed chromatins, broken or lost mitochondria, and expanded rough endoplasmic reticulum in the testis tissue. In comparison, the rats of the high-, medium-, and low-dose ...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
