In-vitro labeling of RBC with 99mTc is an intricate procedure and there is always a need foran alternate blood pool imaging agent. The aim of this study was to prepare an effective nanosized liposome (NLs) similar to human RBC for blood pool scintigraphy. This study formulatesPEG-NLs and non-PEG-NLs using film method plus high pressure homogenization technique.Biodistribution studies were perfo...

different from the adult circulation. In the fetus, gas exchange does not occur in the lungs but in the placenta. The placenta must therefore receive deoxygenated blood from the fetal systemic organs and return its oxygen rich venous drainage to the fetal systemic arterial circulation. In addition, the fetal cardiovascular system is designed in such a way that the most highly oxygenated blood i...

Collateral circulation plays an important role in protecting brain tissue from ischemic damage acute cerebral artery occlusion, and various imaging modalities are used to evaluate collateral circulation. Angiographic techniques, such as digital subtraction angiography multiphase computed tomography (CT) angiography, directly show Meanwhile, hyperintense vessels on f luid-attenuated inversion re...

Acebutolol (AC) is a chiral b-adrenergic blocking drug, which is useful clinically as the racemate in treating hypertension and is metabolized to an equipotent chiral metabolite, diacetolol (DC). In this paper we report a case of a 32 year old woman who was receiving AC during her pregnancy and lactating time for management of hypertension. The maternal plasma level and breast milk as well as c...

background: before the year 1950 treatment of myocardial infarction patients was complete bed rest for several weeks and reduces physical activity for several months. cardiac rehabilitation based on exercise training reduces the effects of deconditioning of bed rest. the primary purpose of this study was to determine the methods and means of prevention and treatment of coronary artery disease. ...

ZARINS, CHRISTOPHER K,, AND DAVID B, SKINNER. Hemodynamics and blood flow distributiun following prolonged circulation at 5°C. Am. J. Physiol. 229(Z) : 275-278. 1975 .-Circulation was maintained in profoundly hypothermic dogs for 8 h at temperatures below 10°C. During cooling to 5°C cardiac output and blood pressure decreased and peripheral resistance rose. Thereafter, circuIatory dynamics rema...
