摘要： The present study was aimed to evaluate the effects of the cyclophosphamide (CY) exposure (Control, 0.032, 0.32, 1.0, 1.6 and 3.2 mg/mL) on the damage in the peripheral blood leukocytes of blunt snout bream for 24 h, which including cell viability, apoptosis, lactate dehydrogenase (LDH) release, mitochondrial membrane potential (Delta psi m), ROS, antioxidant enzyme activity and the relative mRNA levels of apoptosis. Results showed that cell viability and Delta psi m effects of CY were greatly reduced, and occurred in a dose-dependent manner. CY exposure (0.32-3.2 mg/mL) significantly increased the LDH release and induced apoptosis accompanied by Delta Psi m disruption and ROS generation compared to the control. The cellular ROS was significantly increased with increase of CY level from 0.032 mg/mL to 1 mg/mL and the plateau occurred at 0.32 mg/mL. Additionally CY exposure led to oxidative stress as evidenced by significantly the decrease of SOD and CAT and increase of MDA concentration after treating cells with 3.2 mg/mL of CY. Besides, the relative mRNA levels of caspase-3 in the dose of 0.032, 0.32 mg/mL CY, caspase-9 and interleukins-1 beta (IL-1 beta) in the dose of 0.32 mg/mL CY, tumor necrosis factor-alpha (TNF-alpha) in the dose of 0.032 mg/mL CY significantly higher than that of the control. In conclusion, 0.32-3.2 mg/mL CY could lead to cytotoxic effect, inflammatory response and induce the apoptosis of the peripheral blood leukocyte of Megalobrama amblycephala.
