Box Hill Hospital Intensive Care Unit.

The Unit Profile of the Intensive Care Unit at Box Hill Hospital describes the Unit's history and the progression it has made through the past 26 years. Details are given on the type of patients received and the catchment areas this Unit services. The organisational structure and the educational services available are discussed. The breakdown of staff including the nursing and medical staff and the available ancillary services as stated. The critical care course is described in detail to give an outline of and to promote this tertiary based course. It is also hoped this will encourage other hospitals and tertiary institutions to structure such similar courses to provide a more professional education for nurses.

Wear of polyethylene in total joint replacements. Observations from retrieved PCA knee implants.

Observations of wear damage were performed on 12 retrieved porous coated anatomic (PCA) tibial components, all of which were removed because of excessive polyethylene wear. Density measurements of the remaining polyethylene were obtained as a function of depth from the surface of the components. Comparison to previous results from similar studies of total condylar type knee components and total hip acetabular components revealed distinct differences between the types and severity of damage, emphasizing the influence of design factors on the corresponding wear damage. These results confirm previous conclusions that nonconforming articulating surfaces on thin polyethylene components will be at higher risk of damage than more conforming surfaces on thicker components. It also appears that the high cyclic loads to which polyethylene implants are subjected in vivo are most responsible for the degradation in properties of the material near the articulating surface, although the heat pressing of the articulating surface of the PCA components may contribute to the problem.

Intracellular pathway of interleukin-2 receptors studied using immunogold electron microscopy.

The fate of internalized interleukin-2 receptors (IL-2R) on proliferating T cell blasts and Lyt-2-/L3T4- thymocytes was studied by immunogold electron microscopy. Immediately following labeling, IL-2R were found in coated pits and with time there was sequential appearance of gold particles in smooth vesicles or endosomes, multivesicular bodies and lysosomes. Thus the IL-2R appears to be a member of cell surface receptors internalized by endocytosis via coated pits.
