摘要

The general characteristics of normal growing yeast cells fixed with KMn04 are a dense granular cytoplasm devoid of most cytomembranes and mitochondria, and a well defined—usually homogeneous—nucleus located ad¬acent to the central vacuole. On the other hand, starving cells display a progressively less dense cytoplasmic matrix, resulting in enhancement of the visualization of membranous components.nCells irradiated with 100,000 r of x rays undergo only slight changes during the first hours of po stir radiation incubation, but after two days undergo drastic alterations suggestive of lysis. Unusual cell forms, referred to as ameboid, also appear during these late stages of radiation damage.
