ABSTRACT
The authors tested several groups of drug-abusing young adults who were residents of a drug-free therapeutic community. Three instruments were used: staff ratings, sociometric ratings by members of the community, and MMPI scores. All three measures showed objective evidence of decreasing psychopathology correlated with length of time in treatment, demonstrating the effectiveness of the therapeutic community in the rehabilitation of drug abusers. Individuals who left before completing treatment had MMPI scores indicating inability to develop social relationships; this elucidates a probable cause of the dropout phenomenon.

Equipment has been developed for the servo-control of arterial oxygen tension in sick, newborn babies. Using an indwelling umbilical arterial oxygen electrode as sensor, the equipment successfully regulated the administration of oxygen to 12 newborn babies with respiratory distress syndrome, significantly improving the stability of arterial oxygen tension and lessening the duration of episodes of hypoxia and hyperoxia.

A new heated rebreathing system has been developed for the measurement of thoracic gas volume (TGV) and airway resistance (Raw) in infants by the plethysmographic technique. The apparatus has a linear response to flow rates between 0-160 ml-s-1, a dead space of 12 ml and a resistance of 5 cmH2O-1-1-S-1 at a flow rate of 60 ml-s-1. The inclusion of pneumatically operated valves in the apparatus is a major improvement over previous methods of occlusion for TGV measurements. The infant is allowed to rebreathe saturated gas at body temperature through the heated system, thus overcoming a potential source of error when measuring Raw in infants. Using this apparatus, the average coefficient of variation was 3.7% for TGV and 5.9% for Raw.
