Morphometry of fine structural alterations of hepatocytes of Japanese monkeys under fasting stress.
The fine structural alterations of hepatocytes of Japanese monkeys under 4 days of fasting stress were analyzed morphometrically. One of the conspicuous alterations was the enlargement of mitochondria. The average diameter of mitochondria in fasting group increased to approximately 1.89-fold of that in control group, though their number did not change. The number of peroxisomes was 1.36-fold of that in control, though their area did not change. In addition, many of r-ER were swollen and were vesiculated. The appearance of bundle of actin-like stress fiber also increased in the fasting animals. The glycogen area as well as liver weight decreased in fasting group.
