Observations on 67 patients who took Erhard Seminars Training.

The author describes the effects of Erhard Seminars Training (est) on 67 patients--49 who took est during the course of psychotherapy with him and 18 who were seen for evaluation, consultation, or treatment after having taken est. Responsiveness to est was assessed in terms of individually predefined psychodynamics and treatment goals. Of the 49 patients who took est during therapy, 30 were judged to show some positive response and 19 were rated unchanged. The author believes that est often has a strong influence toward psychotherapeutic movement in patients with good ego strength who are motivated to change.

The use of a test for the differential diagnosis of hypercalciuria.

28 renal stone formers (18 men and 10 women) with idiopathic hypercalciuria (IH) and 27 controls have been subjected to a test proposed for the diagnosis of absorptive, resorptive and renal hypercalciurias. Fasting serum calcium concentration, urinary calcium and cyclic AMP excretion were measured after overnight fasting and an oral load of calcium. Absorptive hypercalciuria was demonstrated in 14 patients. High fasting urinary calcium first suggested resorptive or renal hypercalciurias in 5 other patients, but since fasting urinary calcium was normalized following cellulose phosphate therapy, absorptive hypercalciuria was more likely. Renal hypercalciuria was a possibility in 1 single case. Both fasting and post-load urinary calcium were normal in 7 men and 1 woman. The test did not appear as useful as expected since it was of no diagnostic value in about 30% of the cases and erroneously suggested resorptive or renal hypercalciuria in about 15% of the cases. On the other hand it indicated that absorptive IH is common and renal IH exceptional.

Effects of atmospheric ammonia on pulmonary bacterial clearance in the young pig.

Young pigs were exposed to an aerosol of a nonpathogenic strain of Escherichia coli and then were retained in air-pollutant exposure chambers for a 2-hour clearance period. In series 1 (n = 80 pigs), 40 exposed young pigs (principals; 15.5 days of age) were placed in an atmosphere of filtered room air + 50 ppm of atmospheric NH3 during the clearance period; control pigs were exposed to filtered room air without added NH3. In series 2 (n = 24 pigs), 12 exposed young pigs (principals; 6.2 days of age) were similarly maintained, but at a lower concentration of atmospheric NH3 (75 ppm). At the end of the clearance period pigs were killed and pulmonary bacterial clearance was determined. Pigs kept in the NH3-contaminated atmospheres (either concentration) harbored more bacteria, on the average, in their lungs than did the controls. If series 1 and 2 data were combined, pigs kept in the NH3-contaminated atmospheres had 51% more bacteria in their lungs than did the controls. Pulmonic weight and ratio of pulmonic weight to body weight of pigs kept in the NH3-contaminated atmosphere were greater than those of the controls in series 1, but not in series 2. Gross and histopathologic examinations of lung tissue generally revealed no differences between controls and principals in either series 1 or 2.

Indirect hemagglutination using whole mixed antigen for checking toxoplasmosis immunity and for serodiagnosis of human toxoplasmosis, compared with immunofluorescence.

The indirect hemagglutination (IHA) is an easy technic for which it is possible to get commercial reactifs. This methode should be used often for the serodepistage of Toxoplasmosis and control of the immunitry anti-toxoplasmosis. We used a technique with total mixed antigen, that was compared with indirect immuno-fluorescence (I.F.I.), for 623 human serums. The I.H.A. was used with sheep formal hematies and coated with glutaraldehyde, with a total mixed antigen prepared from ultra sonicated parasites. This standardised reactive can be kept one year at 4 degrees C. We worked with U well micro-titration plates and the result is obtained after 2 hours. The I.F.I. technique was made with classical methods using Evans blue counter staining. The reproducibility of the I.H.A., during 366 tests was satisfactory. For the control of the immunity anti-toxoplasmic, the results tallied with both methods in more 95% of cases. Lastly, as test of progression, the I.H.A. with total mixed antigen appear an interesting way for the early diagnosis of the Toxoplasmosis where the reaction seems to be positive as soon as I.F.I.

A study of insulin binding sites in the chicken tissues.

Specific binding of chicken and porcine insulin was demonstrated in isolated chicken hepatocytes, chicken liver plasma membranes and chicken erythrocytes. In the liver, the binding reaction was characterized by a sensitivity and an apparent affinity which were similar to those observed in rat liver and, in contrast, by a decreased number of binding sites. In chicken liver, there were about 5 times fewer binding sites per mg of membrane protein or per unit of cell surface area than in rat liver. In chicken erythrocytes, the number of insulin binding sites per cell was even lower than in chicken hepatocytes. This decreased insulin binding was not accounted for by a faster insulin degradation in chicken tissues. Glucagon binding sites also appeared to be less numerous in chicken than in rat liver, at least at low glucagon concentration; however, the decrease in maximal binding capacity in chicken liver involved insulin and not glucagon binding. That chicken cells are equipped with insulin receptors which are less numerous than in mammalian cells may explain, partly at least, the physiological state of insulin resistance observed in the chicken.
