Abstract

The incidence of spontaneously occurring ventricular septal defects (VSD) in PIKA neonates and its fate during development are investigated. A total of 160 PIKAs were used in the present study. They consisted of three groups; first, 56 live neonates, second, 37 3-week-old live animals and third, 68 animals which had died during the first two weeks after birth from unknown causes. As high as 8.9% (5 cases out of 56) of the live neonates revealed isolated ventricular septal defects of membranous type. Decreased incidence (2.7%) was seen in 3-week-old PIKAs. Its implication and significance are evaluated in the discussion.

摘要

研究了皮卡新生儿自发性室间隔缺损（VSD）的发生率及其在发育过程中的转归。本研究共使用了160只皮卡。它们分为三组：第一组，56只存活的新生儿；第二组，37只3周龄的存活动物；第三组，68只出生后两周内不明原因死亡的动物。高达8.9%（56只中有5只）的存活新生儿显示出膜周型孤立性室间隔缺损。在3周龄的皮卡中发生率降低（2.7%）。在讨论中对其意义和重要性进行了评估。
