Direct Microscopic Observation

The purpose of the present set of experiments was to determine the contribution of the dilator principle, histamine, to peripheral vascular homeostasis. This was done by means of direct microscopic observation of the mesocecal microcirculation through the use of antihistamines. These drugs were found not only to produce a contraction of the microvessels but also to increase the responsiveness to topically applied cate-cholamines and antihistamines as well. The evidence does not preclude the possibility that histamine is a naturally occurring regulator of local tissue blood flow; but on the other hand, one cannot with any confidence accept this possibility.

Blood Flow Measurement

ABSTRACT Indicators which freely cross the capillary wall can be used for measurement of tissue blood flow in many different ways. Basically one can distinguish two categories of methods, viz. the ones where the indicator enters the tissue via the inflowing blood and the ones where the indicator is deposited locally in the tissue. The most important methods are briefly described with special emphasis on the theory of blood flow measurement.

Blood flow and high-energy phosphate (HEP) content were determined simultaneously in multiple microregions of left ventricular subendocardium in 29 normal anesthetized open-chest rabbits by use of a new micromethod to determine whether a direct linear relationship existed between these parameters. Tissue samples weighed 1-2 mg. ATP and creatine phosphate (CP) content were quantitated in quick-frozen hearts by fluorometry at sites where tissue perfusion was measured by H2 clearance by use of bare-tipped platinum electrodes. A series of validation studies were conducted to ensure that 1) no significant damage to the tissue surrounding the electrode occurred during the period of experimentation and 2) no significant loss of biochemical constituents had occurred due to labile processes during freezing or storage of the tissue. Blood flow, ATP, and CP values averaged 79.1 +/- 24.1 (SD) ml.min-1.100 g-1, 4.9 +/- 1.3 mumol/g tissue, and 8.0 +/- 3.0 mumol/g tissue, respectively, and are similar to those reported in studies using larger tissue samples. Correlation between the heterogeneous distribution of tissue perfusion and HEP revealed no direct linear relationship between these parameters in the normal unstressed rabbit subendocardium.
