[Olfactory environment and heterotypical sexual behavior in the castrated male rat].

The display of heterotypical, that is feminine sexual behavior was studied in adult orchidectomized Rats treated with estradiol benzoate and progesterone following exposure to the odor of either male or female urine. The odor of male urine was shown to suppress an inhibitory influence of the olfactory bulbs on the heterotypical sexual behavior in the male Rat.

Prediction of treatment effectiveness in a drug-free therapeutic community.

Treatment effectiveness for drug dependance is evaluated and compared with success rates reported in the literature. Program differences and varying follow-up procedures make assessment difficult. Identical pre- and posttreatment quantitative adjustment indices are recommended in order to improve the measurement of improvement.
