[Lactic acid as a  factor in altering vascular reactivity].
It was shown that the constrictor responses to the electrostimulation of the isolated vessel segments were replaced by dilatation when the drugs were contained in the lactic acid solution. The capacity to constrictor effects was not lost completely, but these effects appeared in repsonse to the intensive stimulation. Changes in the character of these reactions to the electrostimulation were connected with the changes in the pH of the solution, as well as with the specific action of lactic acid.
