[Sexuality. Cultural, social and clinical aspects].

The deep changes in values, beliefs and behaviour, both individual and group, have been examined, referred to the sexuality, by various methods and prospects. Sexual differentiation, typical of the plast, has been rediscussed and modified. As a result of these changes we can talk about old myths, concerning the conception of sexuality in the past, and new myths that concern the present. In this work we have reviewed the different aspects of male and female roles: masturbation, the obsession abort performance, the orgasm and, not last, the sexuality in old age condition.

Contrast effects in flavour preference learning.

In four experiments the role of contrast effects in producing learned flavour preferences was examined. The experiments showed that contrast effects are pervasive in flavour preference learning, producing results that are often paradoxical from a traditional reinforcement point of view. In Experiment 1, rats preferred a reinforced flavour over a nonreinforced flavour more if the reinforcer was 1% sucrose than if the reinforcer was 8% sucrose. Because the cue flavour was dissolved in 8% sucrose, this represents an anticipatory positive contrast effect. In Experiment 2, the relationship between cue and consequence was shown to be important in flavour preference learning, as expected if contrast effects are involved. In Experiment 3, rats preferred a flavour that was reinforced 4 times, and they preferred this flavour more than one reinforced 8 times, presumably because the greater the expectancy of the consequence, the greater the anticipatory negative contrast. In Experiment 4, rats consumed less of 0.15% saccharin if they received 32% sucrose randomly 90 min either before or after the 0.15% saccharin than if they received only 0.15% saccharin, a simultaneous negative contrast effect.

[Surgical aspects in the therapy of Buerger's disease].

Buerger's disease is generally not improved by reconstructive surgery. This one may be expected to succeed only on the atherosclerotic occlusions which eventually occur. Surgical treatment is therefore essentially based on the lumbar sympathectomy, both for trophic purpose as well as for pain relief. Criteria for unavoidable amputations are then exposed.
