This paper describes various aortic parabiotic procedures and discusses various problems concerning these procedures. The most satisfactory results, nearly 100 % of survival rate, can be achieved using longer sections of aortae of 2 to 5.month old rats. In these rats blood circulation between the parabionts has completely been established. ∗PMID: 4264053 [PubMed indexed for MEDLINE] Copyright c...

An accurate and easy to use test circuit has been developed for the performance evaluation of the heat exchangers used in cardiac surgery during extracorporeal circulation. The water part of the heat exchanger is fixed at a flow rate of 15 l/min and at a temperature of 40 degrees C. In the blood side, the flow rate is varied from 1 to 6 l/min and the temperature is 30 degrees C. The use of a pr...

In this study, pulsatile and nonpulsatile assisted circulation were compared to evaluate renal circulation under complete artificial circulation. In addition, differences were also compared between animals supported by high (assist rate 80%)- and low (assist rate 60%)-level artificial circulation. Using 20 pigs, ventricular fibrillation was induced after cardiogenic shock, assist by mechanical ...

this article reviews will focus on the concept and formation of micro particles (mps) in circulation and their role in transfusion medicine and immune system. mps are cell membrane derived vesicles which express markers of their parent cells and are found in circulation at low levels. exact functions of mps are unclear. in here, physiological almost all types of circulating mps including platel...

Bark extract of Pinus pinaster has a long history of medicinal use and is available commercially as herbal dietary supplement with proprietary name pycnogenol. It is used as a food supplement to overcome many degenerative conditions and has been ascribed a very diverse clinical pharmacology [1]. Although there are many potential uses for Pycnogenol, the well-studied use is for improving vascula...

The primitive blood circulation requires intravascular plasma flow. However, it remains unclear whether the onset of earliest blood circulation is dependent solely on establishment of a functional circulatory organ or whether it also requires active processes inherent in blood cells. In this study, we present novel mechanisms for the onset of blood circulation by monitoring fluorescently labele...

The principle that " the movement of the blood is maintained by the heart which acts as a pump" continues to be binding in modern physiology (Evans, 1952). Certain doubts, however, appear when the power of the heart muscle is regarded as the exclusive or even the main source of energy for the whole cardiovascular system. The question may be asked, Is there no other motive force in the circulato...

the sequestration of rat leukocytes and bone marrow cells by the lung vasculature was studied using an isolated perfused rat lung preparation. the passage of latex particles of 7.6 µm in diameter and non-hematopoietic cells through the lung blood vessels was also studied. leukocytes and bone marrow cells were reversibly sequestered from circulation, whereas, latex particles and non-hematopoieti...

In adult cases of bilateral cleft lip nasal deformity, an esthetically satisfying result can not be obtained only by manipulation inside the nose with the nasal tip pointing upward. The nasal tip should be made in a more anterior direction for nasal esthetic improvement. Additional tissue beyond the nose is needed, and the forked flap is a useful method in such cases. However, the blood circula...
