(1) STUDIES OF THE CAPILLARIES IN ESSENTIAL HYPERTENSION AND NEPHRITIS.Since there are a number of discussions on the differentiation between the essential hypertension and renal hypertension, the author examined and compared the skin capillaries of nephritic patients with those of the cases with essential hypertension. The aim of these observations was to determine the difference between the essential hypertension and renal hypertension.Materials and methods : 160 cases with essential hypertension, and 55 nephritis patients were selected and compared with persons who had normal blood-pressure. The last group included 45 subjects admitted to the ""human dock"" station who had normal blood-pressure and had no past history of hypertension, nephritis or infectious diseases and who did not show impaired renal functions in the urine test, PSP test, renal clearance and Fishberg's test.The examination of the capillaries was done at room temperature (15℃-25℃) ; cedar oil was dropped on the cuticle of the left and right digiti annulares which were placed on the same level with the heart. A Columbia Cutaneous Photographic microscope, with 5x ocular and 11x objective, was used.The capillaries were examined for the following items : the width of the arterial limb, the width of the venous limbs, width of the loop, length of the arterial limbs, the number of visible capillaries, the number of windings, etc. The state of the blood-stream was examined for the following items : the continuity of the blood-stream, the degree of the fullness, the presence or absence of granules, and the velocity ; further, the subpapillary venous pleuxus was examined and measured with the aid of micrometer (μ). The blood-pressure was measured by the Riva-Rocci mercury manometer after keeping the patient in the supine position for 15 minutes.Result : (1) Capillaries of the persons with normal blood-pressures.The average width of the arterial limb is 7.7 μ and the average width of the venous limb is 10.5 μ. The average degree of winding is 0.21. The blood-streams were continuous and non-granular, and the fullness was good. The average blood-stream velocity was 172 μ/sec. (Fig. 1-8).(2) Capillaries of patients with essential hypertension.The average width of the arterial limb in 160 patients with essential hypertension was 6.8 μ and the average width of the venous limb was 9.9 μ. The average degree of winding was 0.32. There was a tendency that the blood-pressure rose the blood-stream became granular with lack of fullness and continuousness. The velocity of the stream averaged 124 μ/sec., a finding which is a considerably different from that of the patients with normal blood-pressures (Fig. 9-21).(3) Capillaries of patients with nephritis.Observation was made on 22 cases with acute nephritis and 33 cases with chronic nephritis. The average width of the arterial limb was 6.4 μ and the average of the venous limb was 12.0 μ. The average of the degree of winding was 0.78. In acute nephritis 20 cases had windings in over one third of their capillaries. In chronic nephritis 28 cases had windings in more than one third of the capillaries. Seven cases of acute nephritis and 20 cases of chronic nephritis showed continuous blood-streams. Satisfactory fullness was seen in 6 cases with acute nephritis and 12 cases of chronic nephritis ; and 20 and 29 cases, respectively, showed granular blood-streams. The average velocity of the blood-stream in the former is 125.4 μ/sec. and that in the latter, 129.3 μ/sec. Next, 18 patients were selected who had high blood-pressure. The average width of the arterial limb was 5.7 μ and the average width of the venous limb was 12.1 μ. The average degree of winding was 0.71 and there were 15 patients who had winding in over one third of the capillaries. There were 12 cases who had continuous blood-streams and 7 who had satisfactory degrees of fullness, and 3 cases had non-granular blood-streams. Their average velocity of blood-str
