| 1 | Effect of cholecystokinin and secretin on contractile activity of isolated gastric muscle strips in guinea pigs显示文摘AIM To study the effect of cholecystokinin-octapeptide(CCK-8)and secretin on contractileactivity of isolated gastric muscle strips inguinea pigs.METHODS Each isolated gastric muscle stripwas suspended in a tissue chamber containing5 mL Krebs solution constantly warmed by waterjacked at 37℃ and supplied with a mixed gas of95% O2 and 5% CO2 After incubating for lhunder 1 g tension,varied concentrations of CCK-8 and secretin were added respectively in thetissue chamber and the contractile response wasmeasured isometrically on ink-writing recorders.RESULTS CCK-8 could increase①all regionalcircular and longitudinal muscular tension at rest(fundus LM 19.7%±2.1%,P<0.01;fundus CM16.7%±2.2%,P<0.01;gastric body LM 16.8%±2.3%,P<0.01;body CM 12.7%±2.6%,P<0.01;antrum LM 12.3%±1.3%,P<0.01;antrum CM 16.7%±4.5%,P<0.01;pylous CM12.7%±5.0%,P<0.05);②contractilefrequencies of body LM,both LM and CM ofantrum and pylorus CM(5.1/min±0.2/min to5.6/min±0.2/min,5.9/min±0.2/min to 6.6/min±0.l/min,5.4/min±0.3/min to 6.3/min±0.4/rain,1.3/min±0.2/min to 2.3/min±0.3/min,respectively,P<0.05);③the mean contractileamplitude of antral circular muscle(58.6%±18.4%,P<0.05)and ④the motility index ofpylorus CM(145.0%±23.8%,P<0.01),butdecrease the mean contractile amplitude ofgastric body and antral LM(-10.3%±3.3%,-10.5%±4.6%,respectively,P<0.05).All the CCK-8 effects were not blocked by atropine orindomethacin.Secretin had no effect on gastricsmooth muscle activity.CONCLUSION CCK-8 possessed bothexcitatory and inhibitory action on contractileactivity of different regions of stomach in guineapigs.Its action was not mediated via cholinergicM receptor and endogenous prostagiandinreceptor, | Li W Zheng TZ Qu SY | 2000 | World Journal of Gastroenterology2000，6，1： | 13 |
| 2 | Inheritance of resistance to race 7 of Cercospora sojina in soybeans and RAPD tagging of the resistance gene显示文摘Frog-eye leaf spot of soybean caused by Cercospora sojina Hara is a kind of worldwide disease. Resistance to race 7 of C. sojina was found to be due to a single dominant gene through analyzing resistant behavior of the cross NEAU91212 (susceptible to race 7)× NEAU9674 (resistant to all races). 3 RAPD markers linked to the resistant gene Rcsc 7 were identified using the BSA method. 2 fragments of OPS03620 and OPS03580 amplified with primer OPS03 co-dominantly segregated in the F2 individuals. The genetic distance between OPS03620 and the resistant gene is 8.7 cM. According to the co-dominant marker, the accuracy of predicting the homozygous and heterozygous resistant F2 individuals were 100% and 97.6%, respectively. | Zou, JJ Dong, W Yang, QK Cao, YP Chen, SY | 1999 | Chinese Science Bulletin1999，44，5： | 3 |
