Schistosoma japonicum were obtained from infected rabbits 24 hours after treatment with praziquantel at a single dose of 30,35,40 mg/kg. The drug-induced alterations of histochemistry of the worms have been studied.The results indicated that the glycogen content and AKP (alkaline phosphatase) activities of the worms decreased markedly or disappeared as compared with those of untreated worms; however, the activities of ACP (acid phosphatase) in both treated and untreated worms revealed no apparent change.

The trichomonadicidal activity of tinidazole (Fasigyn) was evaluated by the ire vitro cultivation of Trichomonas vaginalis and Trichomonas hominis with different drug concentrations. The results showed that, after 48-hour incubation with tinidazole, the 100% lethal concentration was 20?g/ml. The trichomonadicidal effect of tinidazole was one titre lower than that of metronidazole. With regard to T. hominis, after 48-hour incubation with tinidazole, the 100% lethal concentration was 20?g/ml. In comparison with metronidazole, the trichomonadicidal effect of tinidazole was similar.

Schistosoma japonicum were obtained from infected rabbits 24 hours after treatment with lower dose praziquantel (30~40mg/kg). The drug-induced tegu-mental surface alteiations of the worms were studied by rcanning electron microscopy. In comparison with untreated worms, the ultrastructures of oral and ventral suckers in both male and female worms were not affected by praziquantel. Major surface alterations including pronounced swellings, erosions and ulcerations were observed,The results showed that the female worms of S. japonicum and those treated with praziquantel at a dosage of 40 mg/kg were more seriously damaged than the male worms and those treated with praziquantel at other dosages.

Celastrol is a type of quinone methyl triterpene isolated from traditional Chinese medicine Tripterygium wilfordii, with pharmacological activities, like anti-inflammatory, immunosuppression and anti-tumor. This study focused on the effects of celastrol on adhesion, migration and invasion of lung cancer cells. The migration inhibition of lung cancer cells induced by celastrol was detected by the scratch test. The invasion inhibition of lung cancer cells induced by celastrol was measured by the transwell experiment. RT-PCR and Western blot were used to determine the effect of different concentrations of celastrol in integrin family and Akt signaling pathway in lung cancer cells. The results showed that celastrol inhibited adhesion, migration and invasion of lung cancer cells and expressions of integrins β3, β4, αv and phosphorylated Akt, GSK-3β, c-Raf, PDK1 in Akt signal pathway in a dose-dependent manner. Therefore, the study implies that Celastrol could inhibit the metastasis of lung cancer cells by suppressing Akt signaling pathway and expression of integrins.
