Procainized murine macrophages fail in the agglutination of opsonized isologous erythrocytes.

Murine peritoneal macrophages exhibit numerous slender microvilli and several invaginations of the cell membrane. By treatment with isotonic 2.10(-2) M procain-PBS the surface of macrophages is smoothed significantly. Isolated macrophages agglutinate opsonized isologous erythrocytes. Procainizing of macrophages inhibits this agglutination. The finding provides evidence for typing of macrophage receptors whether or not sensitive to procain treatment.

Pulmonary atresia with hypoplastic right ventricle. A clinical embryological study.

An unusual case of pulmonary atresia with an aberrant karyotype of 46,XX,t(6;8)(p21.2;q11.2) is reported. Fetal ultrasonic examination at the 20th week of gestation revealed a hypoplastic right ventricle and an intact interventricular septum. Authors summarize their postnatal findings in fetal heart and the large adjacent vessels with special reference to the pathogenesis of this rare congenital heart defect. The observation delineates right-ventricular outflow tract obstruction associated with an abnormal pulmonary blood supply. The anatomy of the systemic pulmonary collaterals was studied and correlated with multifocal disorders in the system of the pharyngeal arch arteries in the early embryonic development.
