Cripps DJ, Liem HH, Muller-Eberhard U: Griseofulvin causing hyperhemopexinemia and hepatic proliferation in mice: an in vivo and in vitro study. J Invest Dermatol. 1977 Feb;68(2):82-7.
Concentrations of hemopexin, a porphyrin-binding serum protein synthesized exclusively in the liver, increased significantly and concomitantly with levels of erythrocyte and liver protoporphyrin and coproporphyrin in mice made porphyric with 1% griseofulvin in the feed. Liver weights of porphyric mice increased remarkably. In comparison with controls, the ratio of the weight of normal to porphyric livers was at 10 days 1:2.1, at 21 days 1:2.8, and at 46 days 1:3.8. This increase in liver size was accompanied by increased cell division. The hepatic hyperplastic tissue fragments survived in vitro for several weeks and could be subcultured. The cultured cells, like those of the original liver, showed intense protoporphyrin fluorescence in the cytoplasm. |
