The effects of pressure breathing for G protection (PBG) on perfusion of the visual cortex were studied in a subject during various high-G stress profiles. Blood flow velocity was measured in the posterior cerebral artery using a transcranial Doppler (TCD) ultrasound instrument. The G profiles examined included gradual and rapid onset rates.

A correlation was established between some parameters of the neuroendocrine system and the indices of the central hemodynamics which is important for the specification of the adaptational role of hormones in acute myocardial infarction and also for the prognosis and selection of the treatment.

In experiments on rats with permanent arterial catheters for blood sampling no posttraumatic increase of plasma norepinephrine and an only slight increase of plasma epinephrine was observed if the animals were traumatized under anaesthesia, in contrast to the considerable increases in the plasma level of both hormones in rats subjected to the injury without anaesthesia. Time and extent of the phosphorylase response of anaesthetized rats after trauma were compared with changes in enzyme activity after i.
