[Morpho-histochemical observations on the liver parenchyma of adult albino rats subjected to acute acoustic stress].
The hepatic noradrenergic innervation and the glycogen cellular content, after acoustic stress, were studied by the fluorescence and P.A.S. methods, respectively, in 7-month-old male albino rats exposed to continuous intense noise for 60' and 8 hours. While the 60'-treatment did not cause noteworthy changes in adrenergic fibers and a decrease in PAS-positive material, the 8 h.-treatment induced a significant increase of catecholamines content, in addition to a non homogeneous response to PAS reaction by hepatocytes surrounding the portal spaces or the lobular central veins. The authors ascribe the effect of the 8 h.-treatment to a partial adaptation of hepatocytes to acoustic stress.
