Giant cell hepatitis in adults.

Giant cell hepatitis is a frequent reaction of the liver to different injuries in newborns and in childhood, but rare in adults. This form of hepatitis is often accompanied by cholestasis and shows fast progression to cirrhosis. In most cases autoimmune, metabolic, toxic or viral origin can be found, but sometimes the etiology remains hidden.

[Morphology and incidence of membranous structures related to endoplasmic reticulum].

Morphology and occurrence of so called tubuloreticular (TRS) and undulating membraneous structures (UMS) connected with the membranes of the endoplasmatic reticulum are described in physiological and pathological conditions. It is established that TRS and UMS represent a cytoplasmatic inclusion of similar type, although of different structures. Occurrence of UMS in human lung-tissue culture, and in transplantable chicken hepatoma induced in a hepatic tumour by MC-29 virus was observed.
