    Notes: Abstract  Mutations causing a visible phenotype in the adult serve as valuable visible genetic markers in multicellular genetic model organisms such as Drosophila melanogaster, Caenorhabditis elegans and Arabidopsis thaliana. In a large scale screen for mutations affecting early development of the zebrafish, we identified a number of mutations that are homozygous viable or semiviable. Here we describe viable mutations which produce visible phenotypes in the adult fish. These predominantly affect the fins and pigmentation, but also the eyes and body length of the adult. A number of dominant mutations caused visible phenotypes in the adult fish. Mutations in three genes, long fin, another long fin and wanda affected fin formation in the adult. Four mutations were found to cause a dominant reduction of the overall body length in the adult. The adult pigment pattern was found to be changed by dominant mutations in wanda, asterix, obelix, leopard, salz and pfeffer. Among the recessive mutations producing visible phenotypes in the homozygous adult, a group of mutations that failed to produce melanin was assayed for tyrosinase activity. Mutations in sandy produced embryos that failed to express tyrosinase activity. These are potentially useful for using tyrosinase as a marker for the generation of transgenic lines of zebrafish.

    Notes: Abstract A 3-month-old girl presented with anorexia, failure to thrive and drowsiness. She was mildly icteric with hepatomegaly and peripheral oedema. Disordered liver function tests were associated with the biopsy appearances of a giant cell hepatitis and with a Fanconi syndrome. At the age of 16 weeks she collapsed with profound hypoglycaemia. Fasting also provoked hypoglycaemia with lactic acidaemia. She became increasingly irritable and hypotonic and, although initially liver and renal function improved, she deteriorated and died of hepatocellular failure and septicaemia. A post-mortem revealed massive fatty degeneration of the liver. The activity of phosphoenolpyruvate carboxykinase in her cultured skin fibroblasts was 16% of controls. Her brother died at the age of 4 weeks of sudden infant death syndrome.

    Notes: Abstract We performed a multicenter prospective randomized controlled trial to determine the efficacy and safety of the surfactant preparation, Survanta (Abbott Laboratories, Chicago, USA), for 750–1750 g infants with idiopathic respiratory distress syndrome, (IRDS) receiving assisted ventilation with 40% or more oxygen. One hundred and six eligible infants from the eight participating centers were randomly assigned between March 1986 and June 1987 to receive either surfactant (100 mg phospholipid/kg, 4 ml/kg) or air (4 ml/kg) administered into the trachea within 8 h of brith (median time of treatment 6.2 h, range 3.2–9.1 h). The study was stopped before enrollment was completed at the request of the United States Food and Drug Administration when significant differences were observed in incidence of periventricular-intraventricular hemorrhage (PIH), between the surfactant treated and control infants. Surfactant treated infants had larger average increases in the arterial-alveolar oxygen ratio, (a/A ratio) (P〈0.0001), and larger average decreases in FiO2 (P〈0.0001) and mean airway pressure, (MAP) (P〈0.017) than controls over the 48 h following treatment. The magnitude of the differences between the surfactant and control groups were 0.19 (SE=0.03) for a/A ratio, −0.28 (SE=0.04) for FiO2 and −1.7 cm H2O (SE=0.70) for MAP. The clinical status on days 7 and 28 after treatment was classified using four predefined ordered categories: (1) no respiratory support; (2) supplemental O2 with or without continuous positive airway pressure (CPAP); (3) intermittent mandatory ventilation; and (4) death. There were no statistically significant differences in the status categories on days 7 or 28 between surfactant and control infants. There were no significant differences between the groups with respect to the incidence of patent ductus arteriosus, bronchopulmonary dysplasia, necrotizing entero-colitis, air leaks or death. There was a statistically significant difference between treated and control infants in the frequency and severity of periventricular-intraventricular hemorrhage (PIH) (Cochran-Mantel-Haenszelχ 2adj=6.36,P=0.01). Hemorrhages occurred in 59.6% of surfactant treated infants and 26.9% of controls. Severe hemorrhages (grades 3 or 4) occurred in 38.5% of surfactant treated infants and 15.4% of controls (χ 2adj=4.01,P=0.045). We conclude that the intratracheal administration of Survanta prior to 8 h of age to infants with IRDS receiving assisted ventilation with 40% or more oxygen results in a reduction in the severity of respiratory distress during the 48 h after therapy. Because of the difference in incidence of PIH between surfactant and control infants in this study, we recommend that future clinical trials of surfactant include more frequent prospective serial ultrasound evaluations for diagnosis of hemorrhage.

    Notes: Summary In 8 healthy subjects the absorption of cimetidine was investigated when given alone, together with 60 ml aluminium/magnesium hyroxyde containing antacid (neutralising capacity 26 mmol HCl/10 ml), and together with liquid metoclopramide 14 mg. The antacid significantly (P〈0.01) reduced the bioavailability (area under the plasma level-time curve) of cimetidine, on average by one third. Metoclopramide also reduced the bioavailability by an average of 22%. The reductions were associated with significantly reduced excretion of cimetidine in urine. There was no change in the half-life or renal clearance of cimetidine, supporting the hypothesis of reduced gastrointestinal absorption. The results indicate that cimetidine and antacids should not be given together, and that the dose of cimetidine may have to be increased if it is administered concomitantly with metoclopramide.

    Notes: Summary The effect of a single dose of cibenzoline ((diphenyl 2,2 cyclopropyl) -2 imidazoline, Cipralan), a new compound with antiarrhythmic properties was studied in 14 patients undergoing routine heart catheterization for suspected coronary artery disease. The effect of the drug on dP/dt, Vmax TP, Vce, negative dP/dt, heart rate (HR), left ventricular systolic pressure (LVSP), left ventricular end-diastolic pressure (LVEDP), cardiac index (CI) and systemic vascular resistance (SVR) was measured before and after drug administration. A significant decrease in left ventricular isometric contraction parameters was manifested immediately after injection, with its maximal effect 2 to 5 min after injection. An increase in HR, a decrease in LVSP, a decrease in CI and an increase in SVR were observed; LVEDP was not significantly altered, nor was negative dP/dt. The effect of the drug on Vmax TP and LVEDP was also examined during two atrial pacing stress tests (APST) done before and 10 to 20 min after drug administration. Although the negative inotropic action of the drug was apparent during the second APST, the effect was less pronounced at higher paced heart rates. No difference in the two tests was found between the maximal paced heart rate, nor was there a difference in the angina threshold. Finally the plasma level of the drug and the changes in certain parameters were compared. A positive correlation was found between the plasma level and dP/dt, Vmax TP and cardiac index.
