Lymphoid organ weights and organ: body weight ratios of growing beagles

Organ Work and Organ Weight

1. The ratios between the rates of growth of the body and of the heart, kidneys, and liver are approximately uniform between 40 gm. body weight and the body weight at maturity in the albino rat. The male and female hearts grow at 0.75 times the rate of growth of the body, the male kidneys at 0.717 times, the female kidneys at 0.648 times, and the liver at 0.838 times the rate of growth of the b...

Tolerated doses of phenacetin in relation to body weight and organ weights.

In a study of the clinicopathologic syndrome of toxicity to phenacetin at the range of the acute, oral LD50j Boyd in 1959 (1) used adult female rats and reported the LD50±SE to be 1.65±0.35 g/kg body weight. In 1968, Boyd and Hottenroth (2) studied the toxicity of phenacetin at the range of the oral LD50 (100 days) and reported the acute oral LD50 ±SE in young male albino rats to be 4.14±0.71 g...

The Relation between Body and Organ Weights in the Rabbit

Data from 645 normal rabbits were used as the basis of an investigation of the relation existing between body and organ weights. Actual and relative weights were correlated with both gross and net body weight. The results obtained varied with different classes of organs but it was found that, in general, there was an agreement between the form and degree of the correlation shown and the structu...

Organ Weights of Normal Rabbits

In November, 1921, a systematic study of normal rabbits was undertaken as a part of a more general investigation dealing with the subject of the animal organism in relation to disease. The present paper on organ weights is based on results obtained from a study of 350 male rabbits killed and examined between January 1, 1922, and July 1, 1924. Methods of conducting the experiments are described ...
