The effects of torasemide on renal glomerular and tubular functions were studied in rats using clearance and micropuncture techniques. A dose-response relationship of torasemide in the range of 0.2-20 mg/kg b.w. on the increase of urine volume, urinary sodium and potassium excretion was established. The effect of a dose of 0.2 mg/kg b.w. torasemide was(More)
A bacterial lysate (OM-85 BV), a preparation of purified bacterial ribosomes (D53) and a placebo were tested for ability to induce the local appearance of specific antibody-containing cells. The three compounds were given orally to 90 children who required tonsillectomy. Surgery was carried out after 1 month of therapy. Frozen-cut sections of each tonsil(More)
