[Statistical analysis of biological breakdown of nicotinic acid 7-14C in rat liver of various weight].

Statistical methods are considered for eliminating the errors caused by the individual fluctuations of the animals organs weight, different ratio of organs weight to the weight statistical processing the data on the dynamics of labelled nicotinic acid evacuation and determination of the acid half-life in the rat liver. The mean liver weight was estimated by means of Huxley's allometry formula. Dynamics of NA was approximated by using the formula kappa=ate-betat in the computer "MHP-2" and the least squares method.
