[Effect of chemicals on rabbits when injected into the testicles. Differences in effects depending on mode of...

Experiments were performed on male rabbits observing the changes in the fractions of protein, glycoprotein, lipoprotein and lipid of the blood. The effect of scarlet R and p-dimethylamino-azobenzene (methyl yellow) was examined. When a solution of scarlet R or p-dimethylamino-azobenzene in paraffin oil was injected into the testicles of the experimental animals the effect was different from any other route of introduction. p-Dimethylamino-azobenzene caused no significant change in the macromolecular fractions of the blood, while scarlet R injected into the testicles caused a significant increase of the total lipids in the second week after the exposition. This effect did not occur when scarlet R was introduced by any other route. According to the authors, their findings may be viewed as a starting point for new approaches to new ideas and ways of thinking.
