Comparison of ventilation effectiveness of the bag valve mask and the LMA Air-Q SP in nurses during simulated CPR.

Unlabelled: In a case of sudden cardiac arrest (SCA) in a health facility there is a procedure to summon a resuscitation team. Nurses are obliged to begin cardiopulmonary resuscitation with chest compressions and implement ventilation using the bag valve mask of 30:2 compressionventilation ratio. Nurses are not allowed to implement methods of advanced airway management.

Hepatocyte transplants improve liver function and encephalopathy in portacaval shunted rats.

Aim: Rats with portacaval shunt (PCS) are useful experimental models of human hepatic encephalopathy in chronic liver dysfunction. We have previously shown that PCS modifies amine neurotransmitter systems in the CNS and increases voluntary alcohol intake by rats. Hepatocyte transplantation, used in acute liver failure, has recently also been applied to chronic liver diseases, which prompted us to investigate whether the altered brain amine system and the drinking behavior in long-term shunted rats could be normalized by hepatocyte transplants.

The response of spleen dendritic cell-enriched population to bacterial and allogeneic antigens.

The dendritic cells (DC) play crucial role in initiation and modulation of immune response especially innate immune response. We investigated the influence bacterial (E. coli and S.

Spleen dendritic cells of recipients of allogeneic but not syngeneic heart grafts internalize donor DNA fragments.

Microchimerism after allogeneic organ transplantation has been widely documented using DNA identification techniques. However, the question as to whether the detected donor DNA is present in the surviving donor cells, recipient macrophages phagocytizing rejected donor cells or recipient dendritic cells internalizing donor apoptotic bodies or cell fragments has not been answered. We provide evidence that allogeneic organ transplantation is followed not only by cellular microchimerism caused by release of graft passenger cells but also dissemination of donor DNA from the rejecting graft cells and its internalization in recipient dendritic cells (DC).

Repopulation of the heart graft with recipient immature dendritic cells prior to transplantation does not prolong its survival.

Experimental studies on allogeneic transplantation have shown that recipient dendritic cells (DC) play a role in peripheral tolerance as well as in rejection of allografts. It is not known whether DC exert their tolerogenic function in the graft or in recipient lymphoid tissue. To answer this question we created a chimeric heart model deprived of its own DC and repopulated by recipient DC.

Biological aspects of limb transplantation: I. Migration of transplanted bone marrow cells into recipient.

The transplanted limb contains bone marrow tissue. The hematopoietic cells contained in the bone of the graft normally differentiate after transplantation and can be released to the recipient. The cells migrate to the recipient bone marrow cavities and lymphoid organs.

Smooth-muscle progenitor cells of bone marrow origin contribute to the development of neointimal thickenings in rat aortic allografts and injured rat carotid arteries.

This study indicates that circulating progenitors of bone marrow origin give rise to cells with smooth muscle-like properties during formation of neointimal thickenings in the arterial wall after allotransplantation and after balloon injury. A segment of abdominal aorta was transplanted from female F344 to male LEW rats, and the grafts were analyzed for male cells by using the gene as a marker. Immunostaining demonstrated that CD45-positive leukocytes made up 35-45% of the neointimal cells during the 8-week period examined.
