Childhood medical and behavioral consequences of maternal cocaine use.

Reviewed available studies of the impact of fetal cocaine exposure on child medical and developmental outcome, as well as the current status of clinical psychological interventions and research strategies. Current studies are inconclusive but suggest that prenatal exposure to crack-cocaine can have significant effects on the growth and neurological development of the infant, with the potential of later learning and behavioral disabilities. Social-environmental correlates of maternal cocaine use are confounding factors with known negative effects on child outcome. Large, population-based studies using multivariate analyses are needed to determine the independent effects of cocaine on child outcome relative to other confounding variables.

Effect of parathyroid extract and of glutaurine (gamma-L-glutamyl-taurine) on the manifestations of osteolathyrism.

BAPN-induced osteolathyrism in young and older male rats was examined for its responses to parathormone-free, gel-filtered bovine parathyroid extract (extract P) and to glutaurine (gamma-L-glutamyl-taurine), the latter being a hitherto unknown putative hormone isolated from bovine parathyroid and reproduced by synthesis. In case of the daily administration of 20 mg BAPN + 0.2 mg extract P/100 g body weight and of 40 mg BAPN + 0.2 micrograms glutaurine/100 g body weight, both substances were found to attenuate the manifestations of osteolathyrism, to a significant extent, without, however preventing their development completely. The significantly decreased Ca, P, chondroitine sulphate and chrondroprotein values due to the administration of BAPN showed a significant, or highly significant, increase for the cartilage in response to extract P, and for both cartilage and bone in response to glutaurine, without however, attaining the control values. Additional evidence has been furnished by the present study that synthetic glutaurine is equal to the parathormone-free, gel-filtered parathyroid extract (extract P) in its attenuating effect on experimental osteolathyrism.
