    (Health & Medical Publishing Group, 1982-11) Barnard, P. M.; Lubbe, J. J. De W.; Rossouw, J. J.; Weich, H. F. H.
    ENGLISH ABSTRACT: Between January 1978 and December 1980, 118 patients underwent saphenous vein bypass surgery for obstructive coronary artery disease at Tygerberg Hospital. Sixteen patients in addition to bypass surgery underwent mitral and/or aortic valve replacement or resection of a ventricular aneurysm. The operative and hospital mortality was 3.0% (4/134) for all patients and 3.3% (4/118) for patients who had aortocoronary bypass surgery as the sole procedure. Follow-up of the surviving patients for a mean period of 16.4 months revealed a low incidence of late myocardial infarction of 3.6% (4/112) resulting in the death of only 1 patient; 89.1% of patients were free of angina pectoris and the majority of these resumed their normal work or enjoyed their retirement.

    'n Nuwe metode vir die bepaliog van serotonien in bloed en serebrospinale vloeistof
    (Health & Medical Publishing Group, 1979) Kriek, J. A.; Bester, A. J.; Rossouw, J. J.
    A new rapid method for the microdetermination of serotonin (5-hydroxytryptamine) in plasma and cerebrospinal fluid is described. A recovery coefficient of 98% was obtained in the present method, with the use of [3H]-hydroxytryptamine creatinine sulphate as an internal standard, compared with recovery coefficients of 31% and 66% for the two existing methods generally used for serotonin determination. This method involves a one-step sample deproteinization by perchloric acid, resulting in a high stability of serotonin.
