The pathogenesis of hyaline globules in liver cells after partial hepatectomy in rats.
To clarify the pathogenesis of hyaline globules in liver cells after partial hepatectomy, the present study was undertaken in rats. When partial hepatectomy was performed by the surgical procedure of Higgins and Anderson, the inferior vena cava pressure was raised, and many hyaline globules, which are very similar to those caused by condensation of the contents of vacuoles in liver cells after temporary pressure elevation of the inferior vena cava, were induced in liver cells. On the other hand, when the median lobe and the left lateral lobe were removed carefully one at a time to avoid operative narrowing of the inferior vena cava, the inferior vena cava pressure was not elevated, and only very few hyaline globules were formed. This suggests that hyaline globules in liver cells following partial hepatectomy in rats may be caused by elevation of inferior vena cava pressure due to narrowing of the inferior vena cava by surgical procedure.
