    Description / Table of Contents: Zusammenfassung Ein Radioimmunoassay zur Bestimmung von Serum-Myoglobin (SMb) wird vorgestellt. Bei 50 gesunden Probanden beträgt der Meßwertbereich 0–90 ng/ml. Serielle Bestimmungen an 10 Patienten mit akutem Myokardinfarkt beziehungsweise Angina pectoris (AP) zeigen, daß SMb bei Myokardinfarkt vor CK und CK-MB pathologische Werte erreicht (im Mittel 250±95 ng/ml bei stationärer Aufnahme 3,3±1,4 h nach AP-Beginn). Die gleichzeitig bestimmte NAC-aktivierte CK liegt zu diesem Zeitpunkt noch im Normbereich und erreicht pathologische Werte erst 6,2±1,9 h nach Schmerzbeginn. Der Peak des Serum-Myoglobins liegt mit 506±194 ng/ml 8,8±2,8 h, der der CK mit 905±475 mU/ml 20,0±7,8 h nach Anginabeginn. CK-MB und CK unterscheiden sich im zeitlichen Verlauf nur unwesentlich. Ein Patient mit ausgeprägter AP hat bei sonst unauffälligem Enzymmuster pathologisch erhöhte SMb-Werte. Methodische und klinische Ergebnisse werden diskutiert.
    Notes: Summary A radioimmunoassay was developed to determine serum myoglobin (SMb). 50 healthy persons showed values between 0 and 90 ng/ml. Serial tests of 10 patients following acute myocardial infarction or during angina pectoris (AP) indicated that SMb reached pathological values before CK and CK-MB (average 250±95 ng/ml at the time of hospitalisation which corresponds to 3.3±1.4 h after beginning of angina pectoris). At hospitalisation the simultaneously determined CK was within normal limits and reached pathological values only 6.2±1.9 h after the onset of angina. Maximum of SMb was 506±194 ng/ml occurring 8.8±2.8 h after the beginning of AP, maximum of CK was 905±475 mU/ml occurring 20.0±7.8 h after AP. CK-MB and CK differed only slightly in their time course. One patient with severe AP had pathologically increased SMb values whilst all other enzymes were completely normal. Methodical and clinical results are discussed.

    Description / Table of Contents: Zusammenfassung Bei 44 Patienten mit chronischer Niereninsuffizienz unterschiedlicher Äthiologie wurde das immunreaktive Serum-Myoglobin bestimmt und mit den Werten von Probanden mit normaler Nierenfunktion verglichen. Es fand sich — unabhängig von der Grunderkrankung — eine hoch signifikante lineare Korrelation zwischen dem Serum-Myoglobin und der Serum-Kreatinin-Konzentration. Bei Patienten mit Serum-Kreatinin-Werten über 550 µMol/1 (6,2 mg-%) lagen die Serum-Myoglobin Konzentrationen fast regelmäßig im pathologischen Bereich. Dies gilt auch für chronische Dialysepatienten. Die Befunde zeigen, daß bei Patienten mit höhergradiger, chronischer Niereninsuffizienz das Serum-Myoglobin nur mit Einschränkung zur Infarktdiagnostik geeignet ist.
    Notes: Summary In 44 patients with chronic renal failure of varied etiology serum immunoreactive myoglobin was measured and compared to values obtained in patients with normal renal function. Irrespective of the underlying disease a highly significant linear correlation was found between serum immunoreactive myoglobin and serum creatinine concentration. In patients with serum creatinine concentrations above 550 µmol/1 (6.2 mg%) serum myoglobin was as a rule elevated above the range found in the controls with normal renal function. This was also true in dialysis patients. These result demonstrate that serum myoglobin may only be used with restrictions in the diagnosis of myocardial infarction in patients suffering from advanced chronic renal failure.

    Notes: Abstract Two age groups of juvenile Synodontis petricola (Group I, 0.5 years and Group II, 1.5 years) were reared on each of five diets: formulated dry diet; Artemia; Spirulina; formulated diet plus Artemia; and formulated diet plus Spirulina. Fish were fed for 84 days and weighed and measured every 14 days. Growth of S. petricola averaged 0.06 mm/day for both age groups. There was no significant difference in percent survival between the fish fed on different diets within each of the two groups but the younger fish (0.5 years) had a significantly lower survival percentage (90.3%) than those in Group II (95.3%). Fish in Group I fed on Spirulina alone grew slower than those fed only on formulated dry feed, whereas the growth rates of fish fed on other diets, or diet combinations, did not differ from each other in both age groups.

    Notes: Abstract To simplify the weaning of clownfish Amphiprion percula from live food to artificial food, and to reduce the costs of feeding live food, three trials were undertaken to determine the best age for weaning. Twenty-nine-day-old post-hatch A. percula were weaned onto a fishmeal/caesin-based dry food which was an acceptable substitute for either Artemia or a moist food comprising Penaeus indicus and Donax serra. Larvae weaned 4 days after hatch (DAH) had lower survival than fish weaned 7 or 10 DAH. In juveniles weaned from 10 to 30 DAH good survival was obtained between 15 and 20 DAH suggesting that this is a suitable window for the weaning of this species.
