摘要:
That preservatives in perishable biological extracts may specifically alter physiological function cannot be precluded in the analysis of experimental results. Whereas 15% ethyl alcohol is shown to significantly lower both vitamin A and carotene concentrations of the liver in growing chickens, little effect is manifest upon similar blood constituents; 0.1% and 1.0% levels of tricresol were without effect upon either vitamin A or carotene in blood or liver, but prompted a pronounced increase in total mean body weight of 30% above the control; alcohol slightly depressed gains. Both preservative materials under study markedly reduced the amount of carotenoids in the shank skins. The extent of such effects in herein reported.
