Similarities between the biochemical actions of cycasin and dimethylnitrosamine.
1. Rats were given the hepatotoxin and carcinogen cycasin by stomach tube. In one experiment, rats whose RNA had previously been labelled with [(14)C]-formate were given the acetate ester of the aglycone form of cycasin, methylazoxymethanol, by intraperitoneal injection. 2. Incorporation of (14)C from l-[U-(14)C]leucine into the proteins of some organs was measured in cycasin-treated rats. Cyca...
متن کاملBiochemical Studies on Shock
During and following the production of shock by hemorrhage in the normal, suprareno-demedullated, and suprarenalectomized rat, the following significant changes in amino acid and carbohydrate metabolism have been observed. 1. In the intact, suprareno-demedullated, and suprarenalectomized rat there is a progressive rise in the whole blood and plasma amino acid nitrogen levels during and after a ...
متن کاملBiochemical Studies on Inositol
In a previous publication (1, Paper V of this series) the purification and properties of the inositol-cleaving enzyme were described. It was shown that a highly purified enzyme was obtained from rat kidneys which cleaved inositol to D-ghCUI’OniC acid. The purified enzyme was shown to possess SH groups and 1 gram atom of iron per mole of enzyme. Both the SH groups and the iron are necessary for ...
متن کاملToxicology of cycasin.
These compounds are extractable from seeds and roots of cycad plants Cycads are ancient gymnospermous plants which are con sidered an intermediate form in plant evolution from ferns to flowering plants. Study of fossils indicates that cycads were distributed widely throughout the world in the early mesozoic period, i.e., about 200 million years ago. The cycads which can be found today are essen...
متن کاملBiochemical studies on regenerating liver.
Regenerating liver of the rat has long been recognized as a source of relatively abundant quantities of homogeneous rapidly growing tissue. Following the removal of the two largest lobes of the liver, the remaining ones, constituting about one-third of the total, enlarge to the size of the original liver in the span of a few days. The work of Higgins and Anderson (l), Brues et al. (2), and othe...
