Abstract
Summary
The test proposed by Majovski et al. for evaluating the effects of vitamin P on capillaries was subjected to a critical study.
The experience of others that previous feeding affects the results of the test was confirmed, but this objection can be overcome by using starved mice only.
The present tests demonstrate that Majov-ski's method is non-specific, however, because a number of solvents used for the rutin, as well as other substances, gave mice the same protection against low atmospheric pressure as rutin did. The drugs which protected mice are not known to have any effect on capillaries; they were: propylene glycol, ethylene glycol, ethyl alcohol and glucose.
