The third position: reflections about the internal analytic working process.

The development of a third position is a key aspect of the analyst's ability to survive in the analytic relationship. In exploring the value of the third position, the author discusses other models relevant to clinical work, including the analytic-therapeutic position, the internal analyst, the alive analytic contact, and the phobic position. A case example illustrates these models and forms the basis for further discussion of the internal analytic working process.

The pinocytic rate of activated macrophages.

Peritoneal macrophages from mice injected 4 days previously with Brewer's thioglycollate medium have a pinocytic rate, in culture, of 190 ng horseradish peroxidase (HRP)/100 mug cell protein/h, compared to the rate of resident peritoneal cells of 53 ng HRP/100 mug cell protein/h. Mice injected with endotoxin or with only certain of the components of the Brewer's medium show an intermediate level of stimulation. The rate of unstimulated, endotoxin-stimulated, or thioglycollate-stimulated cells shows little change over several days in culture.
