Neonatal behavior in full-term small for date.

Fifty newborns, 25 full term SFDs (small for date) and 25 full term AGAs (appropriate for gestational age) were taken up for comparative study of their behavior using BNBAS (Brazelton's neonatal behavior assessment scale). The study revealed that full term SFDs performed significantly poorly on all items under cluster interactive processes compared to their counterparts full term AGAs on day 1. They also showed similar poor performance in clusters of motor processes and organizational processes (State control). Follow up assessment on day 30 revealed significantly better performance in these clusters. However, the performance of SFD babies in all items of cluster of organizational processes (physiological response) was comparable to that of AGA babies in the initial as well as follow up assessments.

The autoimmune response to male reproductive tissues of rabbits. IV. Induction of autosensitization to central accessory tissue by the intraabdominal release of endogenous secretions.

A study is described in which tissue- and secretion-specific autosensitization was induced in adult male rabbits through intraabdominal cannulation of one or more of their central accessory glands. Both primary and secondary humoral antibodies were elicited by this procedure, as determined by tanned cell hemagglutination and passive hemolysis, i.e., complement fixation. The secondary antibody responses were elicited by (i) cannulation of animals which had been previously stimulated by cryosurgery or combined cryosurgery and injection of pooled accessory tissue extract, and (ii) isoinjection of previously cannulated animals with accessory tissue extract. Primary antibody responses were less in animals castrated at the time of cannulation compared to those in noncastrated animals; but, paradoxically, subsequent challenges with tissue extract induced higher secondary antibody titers in castrated animals. These observations may be explained in castrates by (i) reduced uptake of antibodies--a result of the sparing effect on circulating antibodies in castrated animals because of accessory tissue atrophy, or (ii) increased production of antibodies through postcastration immune enhancement. In noncastrates secondary antibody depression may be related to (i) increased absorption of antibodies by an accessory gland complex which is much larger than that found in castrates, or (ii) tolerance, due to exposure of the antibody-producing system to excess accessory tissue antigen.
