[Effects of Shengmai injection on testicular injury after torsion/detorsion in rats of different ages].

Objective: To investigate the different effects of Shengmai injection on testicular injury after testis torsion/detorsion in rats of different ages.

Methods: Sixteen healthy male SD rats aged 3, 6 and 12 weeks were equally randomized into an experimental group (testicular torsion/detorsion plus Shengmai injection) and a control group (testicular torsion/detorsion plus saline). The rat models of testicular torsion were killed 24 h after surgery for the measurement of total antioxidant capacity (T-AOC), superoxide dismutase (SOD) activity and malondialdehyde (MDA) content in the testis.
