The authors examined the blood pictures, especially the platelets and fibrinolytic enzyme systems of blood obtained from the renal artery, renal vein, aorta, vena cava and cutaneous vein by means of Seldinger's method. The subjects (mainly patients with the renal disorders) comprised 75 individuals (46 males; 29 females) with an average age of 37.4 yr (range, 14-to 74-yr-old).
1. The count of platelets in blood from the normal renal artery was almost equal to that from the normal renal vein. The platelet adhesion in the normal renal artery tended more intense than that in the normal renal vein. The platelet aggregation induced at a final concentration of 2×10-5M of adenosinediphosphate in the normal renal vein tended more intense than that in the normal renal artery. However, in some of the 74 subjects so far examined, the difference between the platelet adhesion and the platelet aggregation in the diseased renal artery and the colateral renal vein was observed.
2. The count of red blood cells and the values of hematocrit in the renal artery was usually smaller than those in the other sites including the renal vein, but the difference in the color index of blood among these sites was not observed.
3. The count of white blood cells in the renal vein tended to be larger than that in the renal artery.
4. The value of the plasmin, the anti-plasmin and the fibrin/fibrinogen degradation products in blood obtained from these sites was almost equal.
5. The transmission electron micrograph (TEM) of the diseased renal artery and the colateral renal vein of a case suffering from so-called idiopathic renal bleeding was shown, and the possibility of the difference in platelet-TEM among some of renal disorders was suggested.
