Impairment of isoproterenol, H2 histamine, and prostaglandin E1 response of human granulocytes after incubation in vitro with live influenza vaccines.

The release of the lysosomal enzyme beta-glucuronidase from granulocytes follows incubation in vitro with complement-activated zymosan particles. Release of beta-glucuronidase is inhibited by isoproterenol, histamine, and prostaglandin E1. This in vitro model was used to study the effect of incubating a live, bivalent (A + B) influenza vaccine on the granulocyte response to the agonists described. After incubation in vitro with the live, bivalent influenza vaccine, there was a significantly impaired granulocyte reponse to all 3 agonists. The change in the response of polymorphonuclear leukocytes to isoproterenol was similar to an impairment in beta-adrenergic response found during respiratory infections in vivo. The viral-induced changes in the granulocyte response to isoproterenol may reflect similar alteration in other tissues, such as variable control of the airways and provide one explanation for the occurrence of airway dysfunction during respiratory infections.

Hypertension in radiation nephritis. Report of a patient with unilateral disease, elevated renin activity levels, and reversal after unilateral nephrectomy.

A patient received intensive radiation to the right renal area for abdominal Hodgkin's disease and approximately ten years later severe hypertension developed. The presence of radiation nephritis with a severely shrunken right kidney was demonstrated and this was accompanied by a substantial increase in renin activity from the right kidney. Treatment with propranolol hydrochloride temporarily lowered the blood pressure and peripheral renin activity levels. Subsequent right nephrectomy resulted in a decrease in renin activity and a reversal of the hypertension. The data implicate a renin angiotensin mechanism as probable cause of hypertension in radiation nephritis.

The effects of cosmic Particle radiation on pocket mice aboard Apollo XVII: V. Preflight studies on tolerance of pocket mice to oxygen and heat. Part I. physiological studies.

Tests were carried out on pocket mice to ascertain their tolerance to elevated oxygen pressures alone and to a combination of hyperoxta and heat in excess of that expected during the flight of the mice on Apollo XVII. the mice withstood oxygen partial pressures up to 12 pst at normal room temperature (24 degrees C, 75 degrees F) over a period of 7 days. A few mice previously exposed to increased PO2 died in the course of exposure to an oxygen pressure of 10 pst or 12 psi (517 mm or 620 mm Hg) for 13 d in ambient heat of 32 degrees C (90 degrees F). Supplemental vitamin E and physiological saline loading given prior to exposure had no apparent protective effect. The overall conclusion was that the pocket mice which were to go on Apollo XVII could readily survive the ambient atmosphere to which they would be exposed.

The effects of cosmic particle radiation on pocket mice aboard Apollo XVII: X. Results of ear examination.

In the five pocket mice flown on Apollo XVII, no evidence was found that the inner ear had been damaged, though poor fixation precluded detailed study. On the other hand, the middle ear cavity was involved in all the mice, hemorrhage having occurrred in response to excursions in pressure within the canister that housed the mice during their flight. The same occurred in flight control mice which had been subjected to pressure excursions of much the same magnitude. A greater degree of exudation into air cells and greater leukotaxis were noted in the flight animals than in the control animals. There was no increase in leukocyte population along the paths of the 23 cosmic ray particles registered in the subscalp dosimeters that traversed the middle ear cavities of the flight mice. The increased exudation and the greater response by leukocytes in the flight mice may have been causally related to the lesions found in their olfactory mucosa but there were no data in support of this possibility.

Evolution of diabetes mellitus in a case of Friedreich's ataxia.

A 12 year old girl with Friedreich's ataxia, in whom progression from chemical to severe insulin-dependent diabetes mellitus occurred over a two year period, is presented. During the phase of subclinical diabetes her plasma immunoreactive insulin response to oral glucose was markedly increased, but when she became symptomatic gross insulin deficiency had supervened. This report draws attention to the unusual disorders of carbohydrate metabolism and insulin secretion that may occur in a variety of neurological conditions.
