Formulation of a trace element solution for long-term parenteral nutrition. 1978

J R Matoi, and L P Jeffrey

The reproduction of phage T7 in the presence of hydroxylamine (HA) (mutagenesis in vivo) results in the phenotypic suppression of some amber mutants. The presence of O-methylhydroxylamine (OMHA) results in a similar effect, including a simlilar mechanism for the action of the two compounds. Since the rate of reaction of mutagen with nucleoside residues under these conditions is negligibly low, one of the most plausible explanations of this effect is the enzymic formation of modified precursors and their incorporation into bacterial tRNAs or phage-induced RNA.

D010288	Parenteral Nutrition	The administering of nutrients for assimilation and utilization by a patient who cannot maintain adequate nutrition by enteral feeding alone.
