AIM: To study the influence on the expression of proliferation cell nuclear antigen(PCNA) in rectal carcinoma through retention -enema with FUDR and 5 -FU. METHODS: 80 cases of rectal carcinomas were randomized into three groups: the FUDR group(30 cases), the 5-FU group(30 cases) and normal control group(20 cases), treated with FUDR(500mg), 5-FU(500mg) and normal saline(20ml ) everynight through retention - enema separately for serven days- Mucosa of rectal car cinoma were sampled and PCNA protein were simultaneously detected by imrnunohistochemical method on the first and eighth day. RESULTS: The expression of PCNA was significantly decreased in both FUDR group and 5 - FU group after treatment(P 0. 1). CONCLUSION:The cell proliferation of rectal carcinoma could be inhibited by FUDR and 5-FU through retention-enema. The effects of FUDR was more obvious than that of 5-FU in the same concentration. so the treating method through retention-enema with FUDR should be used as a routine therapeutic scheme befOre operation.

The level of lipid peroxides (LPO)and copper-zinc containing superoxide dismutase(SOD-I) in the gastric mucosa and serum was determined in 141 samples from 25 patients after conventional subtotal gastrectomy (11 cases of Billroth I and 14 cases of Billroth Ⅱ and 11 patients after pylorus and antroseromuscular flap preserving gastrectomy (PAFPG).Those of 11 normal subjects were examined likewise to serve as control.It was found that;1.The average LPO level was much higher and the average SOD-I level much lower in the gastric mucosa after conventional subtotal gastrectomy especially the Billroth type Ⅱ than in those after PAFPG.2.In 36 specimens of stump mucosa,the average LPO level was significantly higher in the tissue around the anastomotic ring than in that of the body of the stump;no marked difference of SOD-I level between the 2 was revealed.3.The LPO value in the stump mucosa was positively correlated to and the SOD-I value negatively correlated to the pH value of gastric juice.Thess findings suggest that the reaction of oxygen free radicals in the stump-mucosa may be influenced by the intragastric pH or by the type of digestive continuity reconstruction,and that the reaction of free radicals specially lipidperoxidation may play a role in the pathogenesis of the lesions in the anastomotic stoma.

0.05).Large amounts of E.coli and intestinal aerobics such as Veillonella spp.,Bacteriodes fragilis,and Clostridium spp.were detected in patients with B-Ⅰ and B-Ⅱ especially the latter but not found in those with PAFPG.These findings suggest that intragastric bacterial overgrowth,can exist in the hypoacidic stumps in the first one to three years afte conventional gastrectomy especially after B-Ⅱ,no such occurrence is found in those after PAFPG since it only moderately reduces the intragastric acidity.
