Carbonic Acid 35-48 oxytocin Oryctolagus cuniculus 108-116 13651574-1 1959 Carbonic acid inhibited the stimulating action of histamine on guinea-pig intestine and of oxytocin on the uterus of many animal species. Carbonic Acid 0-13 oxytocin Oryctolagus cuniculus 91-99 13651574-6 1959 The study of the activity of histamine and oxytocin at different pH in a medium free of NaHCO(3) and buffered with a mixture of sodium maleate and maleic acid suggested that the inhibitory action exerted by carbonic acid was specific and independent of the simultaneous modifications of the hydrogen ion concentration. Carbonic Acid 207-220 oxytocin Oryctolagus cuniculus 43-51
