Towards a family approach in a psychiatric day hospital.

In a day hosptial all staff members must be able to make rapid decisions, even when they cannot refer to their seniors. It is difficult to develop this capability in a teaching day hospital where the staff and student groups are constantly changing. It has, however, been facilitated by regular staff discussions with a visiting psychotherapist. In these staff groups, the study of role attributions and dynamics characteristic of families has diminished the interference caused by 'family' type dynamics in daily professional interaction. The paper describes the effect of such discussion in stimulating the adoption of a treatment approach which takes the family situation into account. This family approach is distinguished from family therapy, and its advantages are discussed.

Embryological study of a T/t locus mutation (tw73) affecting trophectoderm development.

Mouse embryos homozygous for the recessive lethal mutation tw73 show specific defects in trophectoderm shortly after implantation. The trophectoderm and ectoplacental cone fail to form the usual close association with the uterine decidua, and proliferation is markedly reduced. The embryo proper ceases to develop beyond the two-layered stage and degenerates and dies within 5 days of implantation.

Structural similarities between a product of the T/t-locus isolated from sperm and teratoma cells, and H-2 antigens isolated from splenocytes.

Molecules specified by the H-2-linked T/t locus in the mouse are expressed on H-2-negative cells such as early embryos, sperm, and teratoma cells. By means of enzymatic radioiodination of cells and immunoprecipitation of lysates with congenic antiserum, one of these molecules, known as F9, has been obtained from sperm and teratoma cells and compared to H-2 isolated from murine splenocytes. Our studies indicate that both H-2 and F9 have identical molecular weights and subunit structure, including the presence of a B2-microglobulin-like subunit. These findings, taken together with previous studies of TL alloantigens, suggest that a number of gene products of the 9th linkage group show structural homology with each other and, in addition, with immunoglobulin. The genes in question may therefore have arisen from a primitive gene concerned with cellular recognition.
