in critically ill infants and children, intravascular (iv) access is sometimes very difficult. in such cases intraosseous (io) infusion should be used as the method of choice. however, in practice, different problems are experienced with this procedure. to overcome the practical problems and to confirm the efficacy of io infusion in reversing hypovolemic shock, an animal model was used by emplo...
There was investigated the contribution of factors of environment to formation of health for adult population on indicators of mid-annual rates of growth/decrease of disease of system of blood circulation and of some interfaced nosology on an example of the population of Vladimir region. The differential criterion of primary disease of system of blood circulation is considered as an indicator, ...
new procedure being described which involves deliberately preventing blood from passing through the chambers and valves of the heart. In some of these operations, when considerable time is required for their completion, a partial solution has been found in the employment of by-pass techniques. These methods demand extensive vascular surgery to connect the apparatus to the patient, and large vol...
Occipital artery posterior inferior cerebellar artery anastomosis seems to be less effective for ischemia of the rostral brain stem. The authors performed superficial temporal artery superior cerebellar artery (STA-SCA) anastomosis for the rostral brain stem ischemia with excellent results. The patient, a 52-year-old female, was admitted because of vertigo and fainting attacks induced by turnin...
PURPOSE To evaluate the dynamics of choroidal circulation in experimental acute hypertension, using the indocyanine green leukocyte angiography (ILA) method, which the authors have developed for the evaluation of leukocyte dynamics in choroidal circulation. METHODS Japan White rabbits were used in the present study. Leukocytes were collected by centrifugal separation of the autologous blood, ...
BACKGROUND Magnesium (Mg) is the second most relevant intracellular element, which plays an important role in many physiological processes. Magnesium disorders are particularly important in haemodynamically unstable patients, such as patients after extracorporeal circulation. The aim of this study was to analyze the changes in blood Mg levels in patients undergoing coronary artery bypass proced...
the mean percentage of cryptogenic strokes among ischemic strokes is 31%, of which one-third may be associated with patent foramen ovale. the foramen ovale is required for blood flow through the fetal atrial septum. it is formed as of the fourth week of gestation, and this leads to right-left interatrial shunt that allows the passage of oxygenated blood to systemic circulation. in 75% of cases...
1. Circulating kinins were detected and continuously assayed during hypotension due to haemorrhage in dogs, using the blood-bathed organ technique and isolated strips of cat jejunum as the assay tissue. 2. In arterial blood kinin concentrations of 1-5 ng/ml were attained after a hypotension of 35-65 mmHg had been maintained for 10-190 min. When portal venous blood was simultaneously assayed kin...
Involvement of the kinin system was studied in 58 patients during extracorporeal circulation in openheart surgery. At the onset of extracorporeal circulation, there was no increase of free kinin in blood and no reduction of plasma kininogen, when the latter was expressed as gg bradykinin/mg plasma protein. With the lapse of time. kinin in the blood increased significantly, and decrease of kinin...
Hemophilia B, also known as Christmas disease, arises from mutations in the factor IX (F9) gene. Its treatment in humans, by recombinant protein substitution, is expensive, thus limiting its application to intermittent treatment in bleeding episodes and prophylaxis during surgery; development of inhibitory antibodies is an associated hazard. This study demonstrates permanent therapeutic correct...
