Discussion of "interpretation and play".

This discussion addresses the conflict in technique between play versus interpretation. It further considers how the nature of the interpretation may be affected by a consideration of what is being projected into the analyst.

Concern: spurious or real.

This paper is about a group of patients who appear to show excessive concern for their objects, reflecting a combination of a real wish for reparation alongside an attitude of hostility and superiority towards the object. Detailed clinical examples from two patients are used to illustrate a certain combination of characterological defences in these patients who have been severely deprived, and overcompensate for this experienced deprivation by the expression of excessive concern for an object that is simultaneously experienced as hostile and frustrating. Side by side with the partial achievement of the depressive position there is an early 'take over' of the breast, in which the infant 'becomes' the breast and shows behaviour which is in part a fake of a very concerned mother.

Mast cell activation by hornet (Vespa orientalis) venom.

As far as its effect on the activation of rat peritoneal mast cells is concerned, the venom of young hornets (age 0-24 h) differs from that of adult hornets (over 24 h of age). 'Juvenile' venom caused activation mainly in rats previously sensitized to it, whereas 'adult' venom induced activation regardless of presensitization. Furthermore high concentrations of 'adult' venom were cytotoxic to the entire murine peritoneal cell population, but 'juvenile' venom was not toxic.
