[Rare causes of interstitial nephritis in two children].

Unlabelled: Interstitial nephritis (IN) can occur as a result of different injury factors, among them: infections, drugs, toxins. The aim of the study was the presentation of rare causes of IN in 2 patients who were hospitalized in the Department of Pediatrics and Nephrology of Medical University of Warsaw. Case 1.

Comparative morphology of the hepatic and coronary artery walls. Part III. The insignificance of medial morphologic features in the determination of an autopsied unidentified subjects age.

Since hepatic arteries are free of atherosclerosis any possible wall structure change may be attributed to age. We determined the media of hepatic and coronary arteries in view of this assumption. We measured its thickness and myocytic density (per 1 mm2 of cross-section) from specimens collected from autopsied subjects, aged up to 90 years.

Comparative morphology of the hepatic and coronary artery walls. Part I. Differences in the distribution and intensity of non-atherosclerotic intimal thickening and atherosclerosis.

We compared the morphology of the hepatic artery intima which is free of atherosclerosis, with that of the typically atherosclerosis-prone coronary artery. The study group comprised material collected from 116 autopsies. Subjects were aged between 1 month and 90 years.

Prenatal development of coronary arteries in the rat: morphometric patterns.

The aim of this work was to address morphometric patterns of coronary artery (c.a.) development in the rat based on serial section analysis of hearts at different stages of prenatal development.

[Index of histopathological changes in rapidly progressive glomerulonephritis: a preliminary report].

We present the case of an 8-year-old girl with rapidly progressive glomerulonephritis. The activity and chronicity index of histopathological changes in this patient was determined in 2 renal biopsies performed in a 25-month interval. The determination of this index in renal biopsies may be useful in the choice of glomerulonephritis with bad prognosis therapy.
