Effect of quinolinic acid administration on rat liver: ultrastructural investigation.

Summary Quinolinic acid was administered intraperitoneally in a dose of 30 or 60 mmol, once every 24 h for 8 days. Its result in the dose of 30 mmol was the proliferation of smooth elements of the endoplasmic reticulum. The use of quinolinic acid in a dose of 60 mmol was characterized by the presence of more profound damage of organelles, among them the distinct decrease of the rough elements of the endoplasmic reticulum and polyribosomal structures was seen, and moreover, wide areas devoid of organelles were observed.
