Indomethacin and lysine acetylsalicylate in rats with autologous nephrotoxic serum nephritis. Biochemical and morphological studies.
The effects of indomethacin and lysine acetylsalicylate (L-ASA) were compared in rats in which autologous nephrotoxic serum nephritis had been induced. The aim of this study was to offer support to the hypothesis that indomethacin might reduce proteinuria through increased synthesis of glomerular basement membrane by the podocytes. Both drugs were injected intraperitoneally at the dosage of 4 mg/kg body weight daily during a 6-day period into 40 rats rendered nephritic by rabbit nephrotoxic serum injection. Rats treated with indomethacin showed a marked decrease of proteinuria (tested by the 3% sulfosalicylic aicd method) and a clear ultrastructural picture of hyperplasia and hypertrophy of podocytes. Rats given L-ASA showed only a slight correction of proteinuria and less specific ultrastructural modification. These observations suggest that indomethacin decreases proteinuria in nephritic rats not only through its anti-inflammatory activity, but possible also by a peculiar mechanism, namely an increase in podocytic basement membrane synthesis.
Aminonucleoside nephrosis in rats. Ultrastructural findings in the glomerulus by concomitant influence of indomethacin and aminonucleoside.
The concomitant administration of Indomethacin reduced the biochemical signs of the nephrotic syndrome induced in rats by aminonucleoside; in the rats treated with both drugs a morphological picture suggesting activated function of podocytes was found at the electron microscopic examination of the renal glomerular structures, together with the lesions characteristic of the aminonucleoside nephrosis. The possibility is discussed that Indomethacin could modify the permeability of the glomerular capillary wall by stimulating the podocytes to synthesize basement membrane material.

Scanning electron microscopy of podocytes of the renal glomerulus of rats with nephrotoxic serum nephritis.
Nephrotoxic serum nephritis was produced in rats by intraperitoneal injections of rabbit nephrotoxic serum. Heterologous and autologous phases of nephritis were demonstrated by immunofluorescence and ultrastructural studies. Scanning electron microscopy showed changes in the surface of the podocytes, swelling of the arm-like cytoplasmic processes, and disappearance of the pedicles. The podocyte alterations are discussed.

[The use of computed tomography guided needle biopsy in thoracic lesions in childhood].
Percutaneous fine-needle aspiration biopsy (FNAB) is widely used in adult but not in pediatric patients, probably because young patients cooperate little. Twenty-six CT-guided FNABs were performed in children aged 40 days to 15 years (mean: 11.6 years) from January through December, 1993. The lesions were found in anterior mediastinum (17 cases), posterior mediastinum (5 cases) and lung (4 cases). Some specimens were fixed for cytology and some were cultured. Twenty-five of 26 biopsies (96.1%) provided adequate material for the cytologic assay, while in one case the result was poor because of much necrotic material. Cytologic findings were compared with postoperative biopsy results in 9 cases and confirmed by follow-up in 17 non-surgical lesions.
