On the girl's entry into the Oedipus complex.

Detailed child observational study reveals variable pathways by which the girl enters her Oedipus complex. The data of three normal girls are briefly detailed to demonstrate the path each took. The data reported do not support the generalizability of the 1925 postulate that the girl enters her Oedipus complex by way of her castration complex. It is hypothesized that the girl, as well as the boy, enters the Oedipus complex--given a favorable-enough "expectable environment"--from about two and a half years of age on, compelled by a psychobiologically determined gender-related change in her libido and inherited ego dispositions.

Chronic cannulation for intermittent intravenous fluid administration.

A system is described for rapid and effective venous cannulation for long-term administration of fluids in rabbits. This method is completely free of any harness or sling-type apparatus and in no way interferes with the normal mobility of the animal. The animals maintained in this way have participated in programs of tri-weekly administration (2-3 ml/dose) of fluid for as long as 5 mo.

Hypno-analgesia and acupuncture analgesia: a neurophysiological reality?

The effects of hypnosis, acupuncture and analgesic drugs on the subjective experience of pain and on objective neurophysiological parameters were investigated. Pain was produced by brief electric stimuli on the wrist. Pain challengers were: hypnosis (induced by two different video tapes), acupuncture (at specific and unspecific loci, with and without electrical stimulation of the needles), morphine and ketamine. Evaluation of clinical parameters included the subjective experience of pain intensity, blood pressure, puls, temperature, psychosomatic symptoms and side effects. Neurophysiological parameters consisted of the quantitatively analyzed EEG and somatosensory evlked potential (SEP). Pain was significantly reduced by hypnosis, morphine and ketamine, but not during the control seesion. Of the four acupuncture techniques, only electro-acupuncture at specific loci significantly decreased pain. The EEG changes during hypnosis were dependent on the wording of the suggestion and were characterized by an increase of slow and a decrease of fast waves. Acupuncture induced just the opposite changes, which were most significant when needles were inserted at traditional specific sites and stimulated electrically. The evoked potential findings suggested that ketamine attenuates pain in the thalamo-cortical pathways, while hypnosis, acupuncture and morphine induce analgesia at the later CNS stage of stimulus processing. Finally some clinical-neurophysiological correlations were explored.

Comparison of intervertebral disc disease treatment by chymopapain injection and open surgery.

Chymopapain chemonucleolysis was performed on 100 patients with primary lumbar intervertebral disc disease. The results were compared with those of 174 patients who underwent laminotomy, foraminotomy, and discectomy. Primary lumbar intervertebral disc disease was arbitrarily divided into degenerative, complex, previous surgical, and simple disc syndromes. No difference was seen between chemonucleolysis and surgery in the first three divisions; between 55 percent and 60 per cent of patients responded successfully to treatment. In the simple disc division 89 per cent of the surgical and 60 per cent of the chemonucleolysis patients had successful results.
