Objective To evaluate the effect of modified myocardial preservation for surgical treatment of inˉfant tetralogy of Fallot.Methods Fifty-sixinfants,39male and17female with age from3months to12months from January,1997to July,2003were studied.All patients had one stage surgical correction with traditional myocarˉdial preservation（36cases）or modified myocardial preservation（20cases）.

目的 评价改良心肌保护对婴儿法洛四联症期手术治疗的影响方法 1997年1月～2003年7月对56例婴儿法洛四联症病人行一期手术治疗，男39例，女17例，年龄3～12月，平均（9.36±2.80）月，体重3.511kg，平均（8.83±1.25）kg.36例采用传统心肌保护，20例采用改良心肌保护。

The article reviews the advanced research on screening sheepbreeds with high resistance against fasciolosis. Screening sheep breeds with high resistance against fasciolosis has been tested by measuring parameter of plasma such as packed cell volume, mean corpuscular volume, mean corpuscular hemoglobin concen tration, glutamate dehydrogenase, gamma glutamyl transferase and aspartate trans ferase and percent take of metacercariae. High resistance of Indonesian thin tail sheep against Fasciola gigantica has been confirmed. The mechanism of high res istance and the time of killing Fasciola gigantica has also been described.

本文综述了抗片形吸虫病绵羊品种的研究概况，通过红细胞压积、红细胞平均体积、红细胞平均血红蛋白浓度、血清谷氨酸脱氢酶、γ谷氨酰胺转移酶、天冬氨酸转氨酶等血液学参数，囊蚴感染成活率的测定等方法来筛选抗片形吸虫病的绵羊品种，研究证明印度尼西亚细尾绵羊对大片吸虫感染具有较高的抵抗力，并概述了其抗虫感染的机制及杀虫作用时间。
