[Spectrophotometric assay of angiotensin I-converting enzyme (author's transl)].

The method of chemical assay of angiotensin I-converting enzyme described is a modification of the previously published spectrophotometric assay based on quantitation of hippuric acid released from hippuryl-L-histidyl-L-leucine. The new procedure involves extraction of hippuric acid with ethylacetate, evaporation to dryness of the extract, solubilization of the residue with 1 mol/l NaCl and purification with petroleum ether before measurements of the absorbance at 228 nm of the aqueous phase. Under these conditions, hippuric acid insoluble in petroleum ether remains in the aqueous phase, whereas other A228-absorbing materials, readily soluble in the ether and able to interfere with the assay, are eliminated.

[Male sterility and bronchial dilatation (author's transl)].

Male infertility in patients with bronchial dilatation is related to the progressive obstruction of the epididymo-deferential loop. When bronchial dilatation is diagnosed early enough, a spermogram should be performed to conserve the quality of the semen before it starts to deteriorate. In cases of excretory azoospermia it is essential to consider the diagnosis of bronchial dilatation and possible mucoviscidosis among the various etiologies.
