Inhibition of immunoreactive corticotropin-releasing factor secretion into the hypophysial-portal circulation by delayed glucocorticoid feedback.
Nitroprusside-induced hypotension evokes ACTH secretion which is primarily mediated by enhanced secretion of immunoreactive corticotropin-releasing factor (irCRF) into the hypophysial-portal circulation. Portal plasma concentrations of neither arginine vasopressin nor oxytocin are significantly altered in this paradigm. Application of a delayed feedback signal, in the form of a 2-h systemic corticosterone infusion in urethane-anesthetized rats with pharmacological blockade of glucocorticoid synthesis, is without effect on the resting secretion of arginine vasopressin and oxytocin at any corticosterone feedback dose tested. Resting irCRF levels are suppressed only at the highest corticosterone infusion rate, which resulted in systemic corticosterone levels of 40 micrograms/dl. Suppression of irCRF secretion in response to nitroprusside-induced hypotension is observed and occurs at a plasma corticosterone level between 8-12 micrograms/dl. These studies provide further evidence for a strong central component of the delayed feedback process which is mediated by modulation of irCRF release.

Central modulation of immunoreactive arginine vasopressin and oxytocin secretion into the hypophysial-portal circulation by corticotropin-releasing factor.
Corticotropin-releasing factor (CRF), a potent ACTH secretagogue, has been found to exhibit many characteristics of central neurotransmitter/neuromodulatory substances. In this capacity, hypothalamic CRF might participate in postulated autoregulatory processes which regulate net secretion of adenohypophysical ACTH. We have examined the actions of centrally injected ovine CRF on the secretion of immunoreactive CRF, arginine vasopressin (AVP) and oxytocin (OT) into the hypophysial-portal circulation of urethane-anesthetized rats. Our observations do not support a short-term autoregulatory role for CRF. However, central administration of CRF was associated with a dose-dependent inhibition of hypophysial-portal concentrations of immunoreactive AVP and OT, suggesting potentially important central interactions among putative ACTH-regulatory factors.

Evaluation of infants with acidosis using a perinatal "negative factor" score.
Using Prechtl's concept of optimal conditions as modified by Michaelis et al. [7] we analysed the case records of 50 acidotic newborn infants (umbilical artery pH of 7,250 or less) and of 34 controls. Acidotic infants had a significantly higher negative (or adverse) factor score. There was a correlation between the degree of acidosis and the negative factor score. There were, however, no relations between scores in isolated subgroups of negative factors and fetal acidosis though the same was not true for some combinations of subgroups (such as pre-eclampsia, operative delivery, fetal bradycardia in the second stage of labour).

A new gas chromatographic determination of ethylenethiourea residues without derivatization.
A new gas chromatographic method reliable in the microgram range, was developed to measure ETU residues in various crops. Contrary to previously published procedures, this new method does not require prior derivatization of the ETU. The limit of sensitivity was shown to be 0.01 ppm using the flame photometric detector, FPD (sulfur mode, 394 nm).

[Use and evaluation of the usefulness of synthetic materials-- Dallop, Marlex and Gore-tex in alloplasty of ventral hernia].
A trial was undertaken of the usefulness in alloplasty of abdominal hernias of three synthetic materials--Polish polyester net Dallop, polypropylene net Marlex and Gore-tex prostheses of soft tissues. In three 10-case groups of patients referred for correction of abdominal hernias Dallop, Marlex and Gore-tex were used. In the performed operations the use of synthetic materials made possible quick, simple and effective repair of tissue defect in abdominal wall. In early observations after the operations no inflammatory complications, suppuration of wound or recurrence of hernia were noted. Of the three synthetic materials used Gore-tex soft tissue prostheses were found to be most useful in alloplasty of abdominal wall defects.
