Plasma separation in patients with bronchial asthma, atopic dermatitis and hyperimmunoglobulinaemia E.

The effect of intensive plasma separation performed eight times within 5 weeks in four patients with atopic dermatitis, bronchial asthma and hyperimmunoglobulinaemia E was followed as regards clinical symptoms and changes in the concentrations of serum (S) IgE, S IgG, S IgA, S IgM, plasma complement C3 split products, S transferrin, blood eosinophils, chemotaxis of neutrophil cells and histamine metabolites in urine in samples obtained consecutively during the period of observation. The occurrence of circulating immune complexes (IC) was analysed by a polyclonal rheumatoid factor (pRF) agglutination inhibition assay and an IgE IC specific technique. IgE IC were demonstrated in three of the patients prior to plasma separation, complexed IgE was 2-3% of the total concentration of S IgE.

Aminoglycoside toxicity - a review of clinical studies published between 1975 and 1982.

The present survey of aminoglycoside nephro- and ototoxicity covers approximately 10,000 patients reported on in clinical trials published between 1975 and 1982. Included in the survey were clinical trials with at least 15 patients evaluable for nephro and/or ototoxicity provided relevant data were given on methodology, patient material and aminoglycoside dosage. Each publication was evaluated by both investigators and relevant data entered into a chart.

The 125I-Hippuran renogram in rabbit kidneys after graded warm ischaemia.

125I-Hippuran renography was performed after temporary renal arterial clamping in contralateral nephrectomized rabbits. Mean renograms for the experimenttal groups were calculated for 0, 1, 1 1/2, 2, 2 1/2 and 3 h of warm ischaemia. The appearance phase, the 1 min uptake phase and excretion ratio were evaluated.

The effect of chlorpromazine pretreatment on the vascular function of kidneys damaged by warm ischaemia and cold storage in Collins' solution.

Vascular resistance was determined in 40 rabbit kidneys after graded warm ischaemia up to 60 minutes and preservation in Collins' solution for 24 and 48 hours. Half of the animals were treated with chlorpromazine 3.5 mg/kg before induction of the ischaemia.
