Abstract

Annulate lamellae have been observed in the myocardium of 18-day-old chick embryos maintained at the normal temperature of 100 degrees F and at 90 degrees F during the last week of incubation. An increased number of annulate lamellae was observed in heart muscle of embryos incubated at 90 degrees F. This is probably caused by a persistent production of these organelles, since annulate lamellae are present in greater frequency than in 11-day-old embryos incubated at 100 degrees F. In the hypertrophic hearts of 18-day-old embryos incubated at 90 degrees F, the annulate lamellae were associated with a net increase of protein content and an elevated concentration of myocardial glycogen. It is suggested that the increased number of annulate lamellae is a sequela of reduced environmental temperature during incubation.

摘要

在孵化最后一周保持在华氏100度正常温度以及华氏90度的18日龄鸡胚心肌中观察到了环孔板。在华氏90度孵化的胚胎心肌中观察到环孔板数量增加。这可能是由于这些细胞器持续产生所致,因为与在华氏100度孵化的11日龄胚胎相比,环孔板出现的频率更高。在华氏90度孵化的18日龄胚胎肥厚心脏中,环孔板与蛋白质含量的净增加以及心肌糖原浓度升高有关。有人提出,环孔板数量增加是孵化期间环境温度降低的后遗症。
