ABSTRACT
Discharge planners play an important role in managing healthcare costs. Until recent years, the actual dollar costs of healthcare were not a concern of either healthcare providers or patients. This author studied the level of knowledge discharge planners have of actual dollar costs of healthcare, their perception of the patient's level of knowledge, and the impact of the knowledge on healthcare decisions.

Results of growth history studies on IMR-90 and WI-38 showed that the two cell strains were equivalent in population doublings achieved per life span. However, IMR-90 exhibited higher cell yields in phase II than did WI-38. In addition, entry of IMR-90 cells into phase III occurred more abruptly than in WI-38 cultures. Cell sizing analysis showed that phase II and phase III IMR-90 cell populations contained greater numbers of cells in the small volume categories. At senescence, both cell lines contained similar numbers of cells in all size categories. These data suggest that IMR-90 may not be equivalent in all respects to current stocks of WI-38.

The effect of 14 micrometer hydrocortisone (HC) on the proliferative activity of various vertebrate cell lines has been measured. Such activity in human deploid cell line WI-38 was enhanced by HC addition whereas in a number of other vertebrate cell lines under identical conditions HC was inhibitory to growth. We examined the effects of HC on normal human diploid cells other than WI-38; some were stimulated, some inhibited and some were unresponsive. The results suggest that cells derived from different human tissues retain in vitro some aspects of their cell-specific hormonal responses.
