In a pilot study 12 women with severe uterine bleeding received an intravenous injection of 0.2 mg of a vasopressin hormonogen, glypressin. In 11 of the patients a rapid reduction or cessation of blood loss were observed. Two patients had facial pallor following the injection but no other side effects occurred. Five of the older women with long histories of menorrhagia were placed on a regime of one injection of glypressin on the first day of menstruation for six months; in all of them the duration of bleeding was reduced to three days and the monthly blood loss became very slight. On the basis of these results more extensive clinical trials in menorrhagia and metrorrhagia are recommended.

In the present paper the effects of nonapeptide hormones and of some of their chemical analogues were investigated on progesterone and testosterone production in granulosa cells of sow ovaries; the experiments were made in vitro. This objective was given by data on potential regulatory roles of nonapeptides at the level of hypothalamus, pituitary and reproductive organs. The goal of this experiment was to analyze the effects of various doses of oxytocin (OT), arginine-8-vasopressin (AVP), arginine-8-vasotocin and of some of their analogues on progesterone and testosterone production in vitro in granulosa cells of sow ovaries. The production activity of granulosa cells was investigated which were obtained from slaughtered sows without any changes in their reproductive process and abnormalities in their reproductive organs. Follicles of the size 2-5 mm without marked paleness in the early follicular phase were selected for aspiration. Granulosa cells with determined viability (more than 75%) and concentration (2 million/ml) were cultivated in defined culture conditions (37.5 degrees C, 5% CO2) after threefold resuspension and centrifugation of follicle fluid. These hormonal preparations were used in the experiments: pFSH, synthetic OT, synthetic AVP, synthetic AVP with antidiuretic effects and synthetic AVT. Progesterone and testosterone concentrations were analyzed radioimmunoanalytically using commercial kits of the Institute of Radio ecology and Nuclear Technology at Kosice. Statistically significant differences between the groups were evaluated by Student's t-test. The administered preparations were found to influence progesterone and testosterone production in dependence on the doses applied (Figs. 1-6). OT stimulation of progesterone production in granulosa cells indicated its regulatory role in relation to secretion of this hormone.(ABSTRACT TRUNCATED AT 250 WORDS)

Vasopressin is a vasoactive hormone secreted from the posterior pituitary. At low concentration its role is in regulating renal water excretion, but at higher concentrations it has a number of extrarenal actions, including effects on blood flow. To investigate the role of vasopressin in spontaneous migraine, paired samples were collected from 14 subjects (a) during an acute attack of spontaneous migraine, and (b) when symptom-free for at least seven days. During an attack, vasopressin was consistently raised (median (range) 3.5 (1.2-9.6) pg/ml v 0.5 (0.5-1.1) pg/ml, p less than 0.001). The highest vasopressin concentration occurred in the only patient who vomited. The results suggest vasopressin rises during an attack of spontaneous migraine, and this may, in part, be related to emesis. In the majority, vasopressin levels only rose sufficiently to have some renal antidiuretic effect, although in some these levels could have been sufficient to cause alteration in peripheral blood flow. Release of vasopressin may be responsible for the facial pallor and antidiuresis observed in migraine.

Glypressin is a vasopressin derivative which is used in the present study to stop pulmonary bleeding. The effects of endobronchially versus intravenously applied glypressin were examined during diagnostic fibreoptic bronchoscopy in 27 patients. Transcutaneously measured blood gases and haemodynamics were analysed after 1 mg glypressin was given. The glypressin plasma level was 251 fold higher after the intravenous than after the endobronchial administration. After endobronchial application no significant changes were observed for blood pressure, heart rate or blood gases. Following the intravenous glypressin application there was a significant increase in diastolic blood pressure. The bronchial mucosa pallor appeared earlier after topical than after systemic glypressin application. The haemostyptic effect was similar for both routes of application.

One of the important factors in outer space is the absence of gravity (OG). During longterm missions, this factor is responsible for the larger number of anatomical and physiological changes that astronauts experience. The cardiovascular system undergoes these changes with severe intensity, which is part of an adaptation process to the new environmental conditions. The modifications observed in both the anatomy of the cardiovascular system and its hemodynamics occur in two phases. The first phase begins when the astronauts enter into Earth orbit or in interplanetary trajectory and extends until the second or fourth day of the mission. It is characterized by an important shifting of fluids from the lower extremities to the cephalic regions which produces an increase of the venous return and the preload, the heart rate is increased, the blood volume in the thorax is also increased, the cardiac chambers become dilated, and by reflex action, the antidiuretic hormone diminishes, diuresis increases and leads to a virtual state of dehydration. Clinically, the first stage is manifested by headache, dizziness, space disorientation, nausea, anorexia, projectile vomiting, sweating and pallor. This constalation of data is known as "The Space Adaptation Syndrome". The second phase begins at the end of the first phase and finishes toward the fortieth or fiftieth day of the mission.(ABSTRACT TRUNCATED AT 250 WORDS)

Lysine vasopressin and a long-acting analogue N alpha-triglycyl-lysine vasopressin were compared in a prospective randomized double-blind study including 71 women undergoing cold knife conization of the uterine cervix. Hemodynamic and hemostatic variables were studied. N alpha-triglycyl-lysine vasopressin had the following advantages over lysine vasopressin: it gave significantly less skin pallor, becoming evident at a later stage during the operation. The diastolic blood pressure was significantly lower, as also was the incidence of postoperative hemorrhages. Factor VIII related antigen was lower. On the other hand reduction in heart rate (values before conization compared with values during conization) was more pronounced when N alpha-triglycyl-lysine vasopressin was used, but there was no difference in absolute values between the two groups during conization.

Babies with chronic bronchopulmonary dysplasia (BPD) can sometimes develop pallor, systemic and pulmonary edema, oliguria, and hyponatremia not attributable to cardiopulmonary or renal impairment. These signs and symptoms might, however, be explained by inappropriate control of vasopressin secretion. To test this hypothesis, we measured plasma vasopressin and osmolality, serum sodium and potassium concentrations, urine output and osmolality, and free water clearance in 26 normoxic infants with BPD aged 1-4 months. All of these infants required supplemental oxygen (FiO2 0.41 +/- 0.03, mean +/- 1 SE) to maintain O2 saturation of greater than 88%, and six infants also required mechanical ventilation. As controls, 10 infants of similar age but without BPD were also studied. None of the infants had been discharged from the nursery and was receiving any medications, and all were clinically stable when studied. Compared to control infants, infants with BPD had significantly elevated plasma vasopressin concentrations (control 5.2 +/- 0.9 pg/ml; BPD 42.4 +/- 5.1; mean +/- SE, p less than 0.05). Moreover, infants with BPD had hyponatremia and hypotonic plasma, and both urine output and free water clearance were significantly reduced. These data suggest that some infants with chronic BPD have elevated vasopressin levels that are functionally significant. We speculate that excessive stimulation of vasopressin secretion may explain some of the pulmonary and nonpulmonary signs and symptoms in infants with chronic BPD.

Vasopressin (aVP) at low concentrations functions as an antidiuretic hormone and has vasoconstrictive effects. To investigate the possible role of aVP in the pathogenesis of migraine, six patients with a history of induced migraine were given 100 g chocolate, and blood samples for plasma aVP were taken before ingestion and every hour for 4 h. In one patient who presented with severe headache and nausea the base-line plasma aVP concentration was 15.2 pg/ml; it fell to 3.2 pg/ml at 2 h before rising to 10 pg/ml at 3 h and 4 h as the symptoms worsened. In the five patients with moderate or no headache plasma aVP concentrations remained in the normal range (less than 3 pg/ml) throughout. The results suggest that aVP does not have a role in the aetiology of migraine. The possibility exists that during severe attacks of nausea there is release of aVP, which may be responsible for the facial pallor, antidiuresis, and coagulation abnormalities occasionally observed in migraine.

The local analgesic efficacy of a cream formulation of lidocaine and prilocaine (EMLA) in reducing pain at venous cannulation was investigated in children scheduled for elective surgery. Forty children participated in a double-blind, randomized comparison between EMLA and inactive placebo cream. Another group of 18 children without any local treatment was studied as an additional control material. Subjective pain scores, expressed with a visual analogue scale, were significantly lower in the EMLA group compared with both the group treated with placebo cream (P less than 0.001) and the open control group (no cream; P less than 0.01). Local pallor and slight oedema were the only side-effects, registered in both cream-treated groups. A preliminary study was also carried out with 10 children (five with EMLA and five without) in order to determine whether catecholamine and vasopressin levels in venous blood are affected by the stress and anxiety associated with venepuncture in children premedicated with oral flunitrazepam. No significant hormone responses were, however, detected. The lidocaine concentrations measured in venous blood taken from the application site of EMLA cream were low, and there were no measurable levels of lidocaine in simultaneous blood samples from the opposite extremity. In our opinion EMLA cream is safe and alleviates effectively the pain associated with venepuncture, and thus deserves a place in the routine premedication of children.

In a double-blind, randomized study, 50 patients undergoing conization were treated with either lysine-vasopressin (LVP) or its longer-acting analogue Glypressin. Bleeding during the operation and side effects were studied. The hemostatic effect appeared better with LVP than with Glypressin. One postoperative bleeding occurred in the whole series, in a patient treated with Glypressin. The effect on the general circulation, especially with respect to pallor of the skin, was less prominent with Glypressin than with LVP (with the concentrations used in this study).
