The effect of Fusarin C, a new mutagen extracted from Fusarium moniliforme,on murine peritoneal M? activation by measuring M?-mediated MTC ADCC and CS,Fusarin C could inhibit M? activation by both MAF and FDP. The inhibitory effect was dose-and time-dependent and the curves of dose-and time-response were similar in all three assays. There is, however, apparent difference in Fusarin C dose and time needed to induce significant in hibition among these assays. Significant inhibition occured at 0.4?g/ml and 0.5?g/ml for MTC and CS respectively, but 1.6?g/ml for ADCC. Similarly, the minimal period of time necessary to bring about significant inhibition was 2 hr for MTC, but 3 hr for ADCC. Finally, significance of the inhibitory effect of Fusarin C on M? anti-tumor activity in relation to carcinogenesis was discussed.

The inhibitory effect of Fusarin C,a new mutagen isolated from Fusarium moniliforme,on M? activation was investigated.The inhibitory effect of Fusarin C disappeared partially after 24 hr culture in the absence of the mycotoxin and completely after 72 hr.In addition,it could be overcome by high concentrations of M? activating factor or anti-serum to the target cells.

Objective To study the neuropsychological behavior development of preterm infants and low birth weight infants,and to provide a reference to the early prevention and intervention on developmental retardations.Methods A total of 101 preterm infants and/or low birth weight infants received the infant development test of 0 ～ 6 year-old children intelligence developmental scale for neurological development and autism behavior checklist(ABC).Results 25 boys and 5 girls suffered from different psychological mental disorders.The occurrences were as follows:10 cases with mental retardation,9 cases with the language development delay,9 cases with motor retardation,1 case with cerebral palsy and 1 case with autism spectrum disorder.The incidence of intelligence problems were that language retardation (18.9％),the fine motor (16.8％),the adapative ability (12.6％),social action (9.5 ％) and the motor delay (3.2％).There were significant differences in the scores of social communication(x2=8.88,P=0.003),adaptive ability(x2=7.41,P=0.007),the fine motor(x2 =6.22,P=0.01) and total developmental quotient(x2 =5.58,P=0.02) between city children'and rural area.The behavioral problems more consisted in self-care ability and language retardation.Conclusion Preterm infants and low birth weight infants are exposed to language,fine motor,adaptive and communication ability problems,especially the children living in country.It is necessary to improve the early education and intervention for the rural preterm infants and low birth weight infants.

Objective To study the relationship between the intervals of Mitomycin C treatment and cytotoxicity, apoptosis and drug resistance for bladder cancer cells.Methods The bladder transitional cell cancer line BIU-87 was treated for two hours every time for five times with intervals of 24, 48, 72 and 96 hours respectively.Cytotoxicity was measured by MTT.p53,bcl-2,Bax and p170 expression were analyzed by Western blot.Results The IC_(50)(?g/ml)were 4.41,0.71,2.83,4.51and 6.16 with treatment intervals of 24, 48, 72 and 96 hours respectively, p53 and bcl-2 were significantly down-regulated and bcl-2/Bax was re- duced at 24 hour treatment interval but not changed at 48,72 and 96 hour intervals,p170 was not detected at 24 hour treatment interval but increasingly expressed at 48,72 and 96 hours intervals.Conclusion The in- terval of Mitomycin C treatment is closely related with cytotoxieity and apoptosis and drug resistance of blad- der cancer cells.The intervals of intravesical instillations may play an important role in the effect of chemotherapy.
