肾小管细胞质改变Renal Tubule Cytoplasmic Alteration · 肾脏 · 泌尿系统 · NTP ntp-0175
诊断要点:作为雄性小鼠正常背景性所见而存在的细胞质空泡化不必诊断。如果在雄性小鼠中给予处理后(与对照相比)观察到细胞质空泡减少,则该所见应诊断为“细胞质改变(cytoplasmic alteration)”并给出严重程度分级。
病变描述
在某些品系雄性小鼠的外皮质肾小管中,可变的细胞质空泡化是一种正常所见(Figure 1)。这些空泡被认为代表与这些细胞正常变性相关的自噬空泡(autophagic vacuole)。某些化学物质可能减少肾小管上皮中空泡的数量(Figure 2)。

Comment:
Variable cytoplasmic vacuolation in outer cortical tubules of certain strains of male mice is a normal finding ( Figure 1 ). 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 ).
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.
