[Morphological changes in liver tissue in experimental porphyria]. 1978

A Chlumská, and J Dobiás, and V Janousek

Miscroscopic changes in the liver tissue of mice became detectable 42 hours after the administration of gricine through the appearance of porphyrins in the plasma of hepatocytes marked by the enlargement of their volume, nuclei, and nucleoli. 72 hours after gricine, porphyrins were also found in the lumina of capilary bile ducts and hepatic ducts. This was accompanied by dispersion extinction of hepatocytes and pigment accumulation in the plasma of Kupffer's cells. There was histochemically proved increased activity of alkaline and acidic phosphatase, G6PDH, NADH and NADPH tetrazolium reductase. Under electron microscopy, the porphyrins showed crystalline structure, rotated the plane of polarized light, and were marked by red fluorescence.

D011164 Porphyrias A diverse group of metabolic diseases characterized by errors in the biosynthetic pathway of HEME in the LIVER, the BONE MARROW, or both. They are classified by the deficiency of specific enzymes, the tissue site of enzyme defect, or the clinical features that include neurological (acute) or cutaneous (skin lesions). Porphyrias can be hereditary or acquired as a result of toxicity to the hepatic or erythropoietic marrow tissues.
