Comparative studies on the biochemical characteristics of natural actomyosin isolated from PSE and normal pork

Biochemical changes of natural actomyosin from fresh pale, soft, exudative (PSE) and normal pork were studied,and the effects of different storage temperatures and different incubation temperature and times on sample superprecipitation,total sulfhydryl (-SH) content, and ATP (adenosine triphosphate) sensitivity were investigated. The results demonstrated that ATPase activity and thermal stability of PSE actomyosin were lower than those of normal pork; and that PSE actomyosin had higher -SH content than that of normal pork at all incubation temperatures and times tested.

软性角膜接触镜致巨乳头性结膜炎的治疗

目的 对软性角膜接触镜致巨乳头性结膜炎的治疗效果进行分析。方法 采用随机分组将86例160眼巨乳头性结膜炎患者分为治疗组46例88眼,用点必舒眼液、色苷酸纳眼液或欧斯林眼液滴眼治疗。对照组40例72眼：Ⅰ、Ⅱ期用氯霉素眼液滴眼,Ⅲ、Ⅳ期用泰利必妥眼液滴眼治疗。二组进行对比分析。结果经治疗观察结果表明,Ⅰ期二组有效率均为100%;Ⅱ期有效率治疗组为91.7%、对照组为63.6%;Ⅲ期有效率治疗组为80.6%,对照组组为33.3%;Ⅳ期二组有效率治疗组为44.4%,对照组为33.3%。结论 治疗巨乳头状结膜炎具有时间阶段性和特定期间性,该并发症难以预防和治疗,一但发生应中止戴镜,是最好的防治方法。
