[Influence of parenterally injected trehalose in mammals having trehalase activity at different sites].
When trehalose is injected via parenteral pathway into animals lacking kidney trehalase (rat), more than 75 per cent of this disaccharide is eliminated in urine. When the injected animals possess an active kidney trehalase (guinea-pig, rabbit), there is only a low urinary trehalose excretion. Moreover, in rabbit, a marked hyperglycaemia is observed which is due to the rapid hydrolysis of trehalose by kidney trehalase.
