[Quantitative morphometric evaluation of the muscular coat of arteries taking into account their functional state].
The method is suggested for the quantitative characteristics of dynamic vascular tone. It allows the determination of a degree of vascular vasoconstriction as a definite value--an index. This index is determined as real area of vascular cross-sections to their maximum possible area ratio with the inner elastic membrane fully straightened. The index determined in such a way permits to assess quantitatively the degree of vascular vasoconstriction, which is independent of the vascular diameter.
