Abstract
Oxygen uptake and galactose and water transfer by averted sacs of intestine of the fish Gobius paganellus have been measured at 25, 30 and 37°C. The O2 uptake increased with temperature, but it became stabilized between 30 and 37° C. The water transfer from mucosal to intestinal wall increased with temperature. A linear correlation between O, uptake and water transfer to tissue has been observed. The water transfer from mucosal to serosal decreased with temperature rises and became nil at 37 C. The active transport of galactose increased with the temperature reaching a maximum at 30º C. and started to diminish at 37-C. The absence of Na- in the incubation medium inhibited O_uptake and water transfer to tissues and to serosal side. The galactose active transport was ver strongly inhibited by the absence of Na+
