| 摘 要： | 利用冷冻断裂-蚀刻制样技术,在超微结构水平上研究了棉酚甲酸对金鱼精子质膜内蛋白颗粒排列图式(包括晶格区)的影响.结果表明,棉酚甲酸能够使金鱼精子质膜内蛋白颗粒分布不匀:或者颗粒聚集成团,或者质膜内出现无颗粒区域;并且还能使质膜内特定部位晶格区的颗粒排列发生混乱.这些变化表明棉酚甲酸能使精子质膜的有序性降低,也即增加了质膜的流动性.

EEFECT OF GOSSYPOL FORMIC ACID ON PLASMA MEMBRANE OF GOLDFISH SPERMATOZOA |
| |
| Abstract: | The effect of gossypol formic acid on arranging pattern of protein particles including crystal-like structure contained in sperm plasma membrane at ultrast-ructural level has been investigated by using freeze-fracture and etching technique. It has been shown from this experiment that uneven distributions of intramembrane particles are caused by gossypol formic acid: either many particles aggregate together to form large clusters, or plasma membrane in some area could be particles free. In addition, part of crystal-like structure get mixed. Above changes indicate that the orderity of the plasm membrane is reduced, i.e. the fhe fluidity of membrane is increased dy gossypol formic acid. |
