Hypertensin has been assayed in the blood of patients with normal blood pressure and in those with essential hypertension in both the benign and malignant phases. 250 ml. samples of arterial blood were obtained, chemically purified, and concentrated to a volume of 1 ml. These extracts were then assayed in anesthetized rats. The concentrations of hypertensin in the blood of patients with the malignant phase of essential hypertension were found to be greatly increased. The concentrations of hypertensin found in patients with benign hypertension had a moderate degree of overlapping with those found in the normotensive group, but the mean concentration of hypertensin in the former group was twice that of the controls. Although these results are statistically significant, the amounts of hypertensin recovered in the benign group are so small that no conclusions can be drawn as to its effectiveness in producing vasoconstriction in these patients.

1. Van Leersum's range for the normal blood pressure in the rabbit, as recorded by his method, is confirmed. 2. Van Leersum's conclusion concerning the influence of a liver diet on the blood pressure of the rabbit is not substantiated by his data, since the fluctuations of blood pressure he obtained do not surpass his own recorded figures for normal animals. 3. Fluctuations of systolic blood pressure beyond the "normal" range are not necessary for the production of experimental atherosclerosis of the aorta in rabbits. Inversely, egg yolk feeding experiments in rabbits in which atherosclerosis of varying degree, even extreme, is obtained, are not accompanied by an elevation of blood pressure outside the "normal" range. 4. The fluctuations of blood pressure observed during experimental atherosclerosis do not simulate the condition of essential hypertension in man.

Purpose. To study the dynamics of blood pressure (BP) indicators under the influence of exogenously administered melatonin (Melatonin-SZ, Severnaya Zvezda, Russia) with various manifestations of desynchronosis of circadian BP rhythms (arterial hypertension – AH, high normal blood pressure) to determine the scheme of their effective compensation. Material and methods. The study included 101 patients with desynchronosis of circadian rhythms of blood pressure – 52 patients with hypertension, constituting the first and second groups, and 49 individuals with high normal blood pressure, representing the third and fourth groups. Patients of the second and fourth groups received conservative therapy, patients of the first and third groups combined it with melatonin. All patients underwent measurements of office blood pressure, home monitoring of blood pressure (ABPM), electrocardiography, 24-hour blood pressure monitoring (ABPM). Results and discussion. In patients of the first and third groups, compared with the traditional treatment groups, by the end of the observation period, a significantly (p < 0.05) decrease in office systolic blood pressure (SBP) / diastolic blood pressure (DBP) was established: in the first group compared with the second – 1.11 / 1.13 times, in the third group compared to the fourth – 1.43 / 1.58 times; significantly more (p < 0.05) pronounced decrease in SBP / DBP during DMAD – by 1.08 / 1.17 and 1.58 / 1.62 times, respectively, Significantly (p < 0.05) more pronounced decrease in average daily, average daily and average nighttime SBP / DBP during ABPM – by 1.13 / 1.20, 1.11 / 1.20, 1.23 / 1.25 and 1.47 / 1.31, 1.42 / 1.19, 1.54 / 1.41 times, respectively; reliably (p < 0.05) more frequent registration of the dipper rhythm type SBP / DBP – 1.6 / 1.4 and 1.6 / 1.4 times, respectively. In addition, the dynamics of patients in the first and third groups showed a significant (p < 0.05) decrease in the mean daily and mean nighttime SBP / DBP variability (SBP in the first group by 27.3 and 41.3 %, respectively; DBP in the first group by 20.1 and 26.3 %, respectively; SBP in the third group by 13.5 and 25.2 %, respectively; DBP in the third group by 12.2 and 28.2 %, respectively). Conclusions. With various manifestations of desynchronosis of circadian rhythms of blood pressure (AH, high normal blood pressure), the prescription of melatonin (Melatonin-SZ, Severnaya Zvezda, Russia) at a dose of 3 mg per day 30–40 minutes before bedtime for a month against the background of non-drug therapy and antihypertensive drugs led to a significantly more effective decrease in blood pressure at its office measurement, DMAD, ABPM with an improvement in the circadian rhythm of blood pressure and normalization of blood pressure variability.
