SummaryHigh concentrations of nicotinamide exert a synergistic effect upon penicillin inhibition of Staphylococcus aureus. Nicotinic acid was inactive in this respect. No evidence for a reaction between nicotinamide and penicillin could be found. Alt

Two variant forms of porcine relaxin (B and C) are active in producing relaxation of the guinea pig pubic symphysis and in effecting uterine growth in rats. Only relaxin B, however, is active in the mouse pubic ligament assay. These two hormones were

The effects of porcine relaxin and insulin on blood glucose and on uterine and diaphragm glycogen were measured after 3 and 24 hr in alloxan-treated, hyperglycemic rats. Insulin caused a decrease in blood glucose and enhanced the glycogen concentrati

SummaryA combination of exclusion chromatography on Bio-Gel P-10 and electrophoresis on a column of Sephadex G-25 at pH 9 has been used to isolate three proteins with relaxin activity from a porcine relaxin concentrate (NIH relaxin). The three protei

The possible contribution of relaxin to the support of uterine accommodation during late gestation by retarding tissue lysis was examined using the involuting postpartum uteri of unilaterally pregnant rats. In otherwise intact animals, twice-daily ad

1. 1. Two methods for the prediction of protein secondary structure have been applied to the amino acid sequences of porcine relaxin and bovine insulin. A comparison has been carried out between the predicted secondary structure and the known structu

SummaryFrom 5 to 10% of the biological activity of a porcine relaxin concentrate is contained in a fraction with a molecular weight which is considerably higher (∼42,000 daltons) than that of relaxin itself. Exposure of this material to a low conce

1. 1. SPl-Glutamate dehydrogenase (GDH) has been isolated from cotyledons of pregnant bovine uterus. 2. 2. Although the specific activity of uterine GDH is relatively low, its enzymatic parameters are similar to those of the liver enzyme. 3. 3. The m
