They are thought to represent autophagic vacuoles associated with the normal degeneration of these cells. Some chemicals may decrease the number of vacuoles in the renal tubular epithelium ( Figure 2 ). ## 英文原文 · Recommendation Cytoplasmic vacuolation that is present as a normal background finding in male mice does not have to be diagnosed. If a decrease in cytoplasmic vacuoles is seen following treatment in male mice (compared with controls), then this finding should be diagnosed as "cytoplasmic alteration" and given a severity grade.
