- W200788645 abstract "Comparative study between heart and kidney microcirculations was made by a microvisualization technique. To visualize (i) the subendocardial microcirculation and (ii) intrarenal microcirculation (especially afferent and efferent arterioles), we developed a needle–lens probe videomicroscope (magnification: 200–400). To observe subendocardial arterioles, we introduced the needle–lens probe (4 mm) onto endocardial surface through the mitral valve from a small incision at the left atrial appendage in dogs. The diameter of subendomyocardial arterioles changed during a cardiac cycle by about 20%, while the change in subepicardial arteriolar diameter was almost negligible. The subendocardial blood flow velocity waveform visualized by a light marker exhibited an exclusively diastolic pattern with reverse flow during systole, while the subepicardial flow direction was forward through a cardiac cycle. To visualize the intrarenal microcirculation, we inserted the cone-shaped needle–lens into kidney directly from the renal capsule in normal (WKY), spontaneous hypertensive rats (SHR), and streptozosin induced diabetic rats (STZ). The afferent and efferent arteriolar sizes in WKY were nearly equal, i.e., 12 and 9 μm, respectively; however, the afferent arteriolar size in SHR was smaller (about 60% of WKY) and that in STZ was larger (120% of WKY). The diameters of efferent arterioles in both SHR and STZ were similar to WKY. In conclusion, the microcirculations in the heart and kidney are of different dynamic behaviors: (i) with motion including diameter change and “slosh phenomenon” of flow waveform in the heart and (ii) without dynamic motion, but delicate vasomotor tone control of afferent and efferent arterioles in the kidney." @default.
