The activity of SOD in the plasma of patients with NPC and the effect of the culture supernatant of NPC cell line (CNE-2s) on SOD activity were examined by method of Oyanagui. The results showed that the activity of total-SOD, Mn-SOD, CuZn SOD in the plasma of patients with NPC decreased significantly than those of the normal (P

AIM: To investigate the expression of nitric oxide synthase (NOS) and its clinical significance in hepatic cellular carcinoma (HCC). METHODS: The NOS1, NOS2 and NOS3 of 51 cases of HCC and 46 cases of liver tissue beside carcinoma (LTBC) were detected by immunohistochemistry. RESULTS: The expressive rates of NOS1, NOS2 and NOS3 in LTBC were significantly higher than those in HCC ( P
