Effects of position in the uterus on fetal mortality and on response to trypan blue

ABSTRACT In three strains of mice and an outcross of each to ZRDCT-An, the fetuses occupying the implantation site nearest the common uterus are less likely to survive than the ones nearest the ovary. When dams are treated with trypan blue, mortality in excess of the spontaneous frequency seems greater in the ovarian than in the cervical position. Both the heterogeneity of distribution of spontaneous mortality and the suggestion of treatment-position interaction show the importance of intra-uterine selection upon survival of a developing organism. None of the data are inconsistent with the hypothesis that one mechanism of selection is through variations in blood supply in different regions of the uterus.

THE PATHOGENIC OMENTUM

Congenital defects of the omentum may so alter its form as to destroy its protective mechanism and make it a menace to life. Clinically speaking, the intraabdominal bands so often found in relation to the colon are of two types: first, those continuous with and structurally analogous to the omentum, and, second, the more frequently and extensively studied true pericolic membranes. The latter are serous structures more or less closely resembling the peritoneum, and carrying a variable blood supply but no fatty tissue. In the course of a recent study comprising the resection of 169 pathogenic colons, we have been struck with the importance of making a clear distinction between these two anatomically separate structures and their relative capacities for causing serious harm to the colon. Omental bands or deviants, when extensive, are prone to contain a great deal of fibrous tissue which is secondary to the well known bacteriolytic
