Randomized Controlled Trial Clinical TrialHypnosis, suggestions, and altered states of consciousness: experimental evaluation of the new cognitive-behavioral theory and the traditional trance-state theory of "hypnosis".
Sixty-six subjects were tested on a new scale for evaluating "hypnotic-like" experiences (The Creative Imagination Scale), which includes ten standardized test-suggestions (e.g. suggestions for arm heaviness, finger anesthesia, time distortion, and age regression). The subjects were randomly assigned to one of three treatment groups (Think-With Instructions, trance induction, and Control), with 22 subjects to each group. The new Cognitive-Behavioral Theory predicted that subjects exposed to preliminary instructions designed to demonstrate how to think and imagine along with the suggested themes (Think-With Instructions) would be more responsive to test-suggestions for anesthesia, time distortion, age regression, and so on, than subjects exposed to a trance-induction procedure. ⋯ The results thus supported the new Cognitive-Behavioral Theory and contradicted the traditional Trance State Theory of hypnosis. Two recent experiments, by De Stefano and by Katz, confirmed the above experimental results and offered further support for the Cognitive-Behavioral Theory. In both recent experiments, subjects randomly assigned to a "Think-With Instructions" treatment were more responsive to test-suggestions than those randomly assigned to a traditional trance-induction treatment.

ReviewThe role of humoral and cellular immune factors in neuromuscular block in myasthenia gravis.
The neuromuscular block of myasthenia gravis appears to be due to decreased and abnormal responsiveness of the motor end plates to transmitter, and perhaps a decreased number of functioning end plates. The presence in myasthenic patients of serum globulins that bind to a bariety of cellular and subcellular components, and of thymic abnormalities, has encourage the search for humoral and cellular immune factors that may be responsible for the anatomic and functional defects. Attempts to demonstrate neuromuscular blocking activity in the serum have been inconclusive. ⋯ While studies on the immunological reactivity of lymphocytes from myasthenic patients have shown some differences from those of normal subjects, neuromuscular blocking activity has not been demonstrated in these cells or in their extracts. There is increasing evidence that the neuromuscular block of myasthenia gravis is due to alteration of the acetylcholine receptor. The recent reports of antibodies to acetylcholine receptor in the serum of myasthenic patients suggests that these may be responsible for the neuromuscular block, but such action, and the cause of antibody release, remain to be determined.

Immunotherapy of cancer with cell wall skeleton of Myocabacterium bovis-Bacillus Calmette-Guérin: experimental and clinical results.
Adjuvant and antitumor activities of CWS prepared from cells of mycobacteria, nocardia, and corynebacteria were examined. Oil-attached CWS of M. bovis BCG (BCG-CWS) stimulated the generation of cell-mediated cytotoxic effector cells in mice. Tumor growth was suppressed in mice inoculated intradermally with a mixture of oil-attached CWS and living tumor cells. ⋯ The intravenous injection of oil-attached BCG-CWS prevents the appearance of lung cancer in rabbits by the instillation of chemical carcinogens. It was also shown that treatment with oil-attached BCG-CWS was able to elevate the immunologically depressed state of tumor-bearing mice to a normal level, as determined by a cell-mediated cytotoxicity assay that empolyed chromium release as the standard. Preliminary results suggest that oil-attached BCG-CWS is useful as an immunotherapeutic agent for both lung cancer and for malignant melanoma, leukemia, Hodgkin's disease, and other neoplastic diseases and that this agent operates without any significant complications.
