AIM To investigate the effects of piroxicam on transplanted Sarcoma S180 and the expression of COX 2,VEGF,FGF 2 and microvessel density (MVD) in tumor tissue METHODS Kunming mice were randomizedly divided into control group, FT207 positive group and 5, 2 5, 1 mg?kg -1 piroxicam groups One day after inoculation of 0 2 ml S180 cell suspension, FT207 and piroxicam were given by gastric intubation for 9 days The inhibitory rate on S180 was calculated routinely The expression of COX 2,VEGF,FGF 2 and MVD was detected by immunohistochemistry RESULTS The growth of S180 was significantly inhibited by piroxicam at the doses of 5, 2 5, 1 mg?kg -1 with the inhibitory rate of 31 4%,40 7% and 34 9% respectively The expression of COX 2 in the tumor tissue was also inhibited by piroxicam. Accordingly the expression of VEGF,FGF 2 and MVD was markedly inhibited in dose dependent manner by piroxicam CONCLUSIONS The results suggest that piroxicam has inhibitory effects on S180,and it also decreases the expression of COX 2 in tumor tissue. There is a relation ship between the expression of COX 2 and angiogenesis related factor Antiangiogenesis may be another mechanism for piroxicam to exert its chemopreventive and treatment effects.

Objective To prepare the infected Oncomelania hupensis by artificial method for the research on the activity, vaccine, and genetic variation of Schistosoma Japonicum (S. Japonicum).Methods The mature eggs of S. Japonicum were collected by Nylon silk method and the miracidia were incubated under appropriate conditions. Negative snails were infected with miracidia in different proportion by means of individual or collective infection to seek the best method and proportion of infection between miracidia and snails. Infected snails were divided into 12 groups in total. Ⅰ-Ⅵ groups were for individual infection and Ⅶ-Ⅻ groups were for collective infection. There were 200 snails in each group. The infection ratios between snails and miracidia in Group Ⅰ-Ⅵ or screened, numbered, and reared singly. The amount of cercariae was calculated once every 10 days until the infected snails died. Then cercariae shedding quantity, infection quantity, and mortality of infected snails in every group were compared to find the best infection method and the best infection proportion between miracidia and snails. The cercariae were collected from the first generation of infected snails and were used to infect experimental animals. The mature eggs of S. Japonicum were saved from the infected experimental animals and incubated to get miracidia. The snails were artificially infected by miracidium to get the second generation of infected snails. The developmental rates of adult worms, the egg density in fecal and liver were compared between artificially and naturally infected snails. Results In individual infection GroupⅠ-Ⅵ,the average infection value of snails were 0±0,22.7±4.2,31.7±4.5,53.0±5.3,39.3±5.9,32.7±4.7,the average fatality of snails were 21.7±3.1,25.0±3.6,31.3±4.9,44.7±6.5,78.3±9.5,89.7±13.6, and the average value of cercariae shedding from infected snails were 0.0±0.0,308.0±96.6,428.1±146.2,527.0±171.1,571.4±148.9,602.9±356.3, respectively. In collective infection Group Ⅶ-Ⅻ,the average infection value of snails were 0±0,12.3±2.5,18.7±4.7,28.3±4.2,33.3±4.7,29.3±5.5,and the average fatality of snails were 22.7±3.8,23.7±4.5,28.3±5.5,47.0±9.5,75.7±8.5,86.3±12.2, and the average value of cercariae shedding from infected snails were 0±0,244.5±57.3,292.3±74.8,347.1±100.8,477.2±142.1,447.3±161.4, respectively. The second generation of artificially infected snails was obtained successfully. The average infection rate and fatality rate for the second generation of artificially infected snails were 24.65% and 24.50%, both of which were not obviously different from that of the first generation of artificially infected snails (P>0.05). In the animal experiment, the worm growth rate for the naturally infected snails, the first or second generation of artificially infected snails were 68.50%,73.50% or 71.00%. There was no obvious difference among them (P>0.05). The fecal (or liver) eggs per gram for the naturally infected snails, the first or the second generation of artificially infected snails were 1 503±269,1 683±233, or 1 541±117 (or 6 641±1 819,6 272±1 419, or 7 263±1 643). There was no significant difference among the 3 groups (P>0.05). Conclusion Infected snails can be obtained through the artificial method by using S. Japonicum miracidia to infect snails. Individual infection has the advantage over collective infection. The optimal proportion of infection between first and the second generation of artificially infected snails in the average of cercariae shedding, infection, and fatality average of snails. There was no significant difference between artificially and naturally infected snails in the developmental rate of adult worms, fecal and liver eggs per gram.
