A patient developed acute phthisis bulbi and external ophthalmoplegia with herpes zoster ophthalmicus (HZO). The clinical course and ocular complications of HZO are described briefly and the cause of phthisis bulbi and external ophthalmoplegia in zoster ophthalmicus is discussed. It is suggested that the acute hypotonia in HZO is due ...

Treatment of Avena coleoptile sections with IAA results in a rapid decrease in the level of lipid peroxidation (LP), as measured by the thiobarbituric acid reaction for malondialdehyde (MDA). The response is specific for active auxins, is nearly saturated by 10(-6) M IAA and occurs even when turgor is reduced ...

Investigation of Ba2+ effects on fast and slow PIII responses in isolated bullfrog retina revealed that Ba2+ suppressed slow PIII completely with little effect on fast PIII. A light-induced [K+]0 decrease in the photoreceptor layer was observed in spite of Ba2+ perfusion, indicating the suppressive action of Ba2+ on the ...

The study investigated the construct validity of the Rorschach space response by factor analyzing the stress-coping reactions to highly stressful conditions. Self-report reactions to stress of 173 medical students measured on the Habits of Nervous Tension showed that space responding loaded highest on a factor identified as "anger affect" and ...

Several types of osseous outgrowths that may appear on the dorsal surface of the talus are described. A normal talar ridge, located between the trochlea and distal articular surface of the talus, may hypertrophy in response to exaggerated stress. In addition, typical osteophytes may appear, indicative of osteoarthritis of the ...

An overview of the plan for medical response in the event of a disaster in the Netherlands is presented. An idealized evaluation of the response capability, as well as the probable actual ability, is reviewed. The plan involves a response to the disaster site by teams comprising a surgeon, anesthesiologist, ...

A case of sotalol-induced polymorphous ventricular tachycardia (torsade de pointes) is presented. The patient had moderately prolonged Q-T interval before medication with sotalol with further prolongation after application of this drug. Electrophysiological study during rechallenge with sotalol demonstrated a uniform ventricular tachycardia with a somewhat polymorphous onset; whether or not ...

The subjective response to antipsychotic medication was systematically evaluated in two samples of schizophrenic patients, one treated with haloperidol, the other with thiothixene. For both groups, a dysphoric response to the first dose was found to be a powerful predictor of noncompliance. A persisting dysphoric response was associated with a ...

Methanol extracts of bracken frond and rhizomes prepared using a metallic extraction vessel, were proved incapable of producing bracken poisoning in calves. Nevertheless, they contained appreciable quantities of pterosins and pterosides. Thus the poisonous principle(s) in bracken responsible for the toxicological effects are not associated with these major sesquiterpenoids of ...

Groups of clients exhibiting both self-injurious behavior (SIB) and stereotypy, stereotypy alone, SIB alone, or neither of these types of behavior were rated in terms of response to sedative-hypnotic medication. Sixty-eight percent of the clients with both SIB and stereotypy maintained wakefulness and were either resistive, combative, restless, uncooperative, or ...

The experiment monitored the use of an experimental central warning system by experienced pilots. The warning system incorporated audio warnings, voice messages, and panel legends. The voice messages were produced by a Votrax synthesizer. Warning responses were assessed during a realistic flying task. Audio warnings produced significantly faster responses than ...

The only rational approach to the potential chaos of a mass disaster is thoughtful predisaster preparation and realistic but optimistic confrontation of the situation. An appropriate response implies accurate assessment of the magnitude of the disaster, the establishment of a reliable and effective communication system, a realistic inventory of and ...

Neutroplasts, which are vesicles consisting of cytoplasm enclosed by plasmalemma, have been prepared and found to be incapable of degranulation in response to f-Met-Leu-Phe. However, neutroplasts generate superoxide anion in response to f-Met-Leu-Phe and PMA, and therefore, degranulation is not essential for superoxide anion generation. In addition, neutroplasts aggregate and ...

The attention of physicians is being drawn to the issue of nuclear weapons and nuclear war, creating controversy about whether a political concern is appropriate for health care professionals. The use of nuclear weapons would incur human death and injury on a scale both unprecedented and unimaginable, and possibly damage ...

This study addresses the current capacity of the government to cope with the health and medical aspects of a national crisis situation. The report includes a historical description of health mobilization planning and an assessment of the current mobilization preparedness in terms of responsibilities and current mobilization availability of resources. ...

"Induced hydrolysis" a new hydrolytic activity, was found by measuring AMP-production during aminoacylation of tRNAPhe-CCA by yeast phenylalanyl-tRNA synthetase in the presence of tRNAPhe-CC under conditions of low ionic strength at pH 8.5. Experiments using the elongation factor Tu . GTP provide evidence that transfer of phenylalanine to the tRNAPhe-CCA ...

In the following essay, the theoretical apparatus for distinguishing various types of collectivities (aggregates and conglomerates) is described. This is followed by a consideration of how responsibility ascriptions to different types of collectivities are to be understood vis à vis those to individual group members. It is suggested that the ...

Data from the group-administered Rorschach for 77 medical students showed that subjects who gave space responses on cards other than Card IX are more likely than non-space-respondents to respond to the faintly colored center Card IX regions. Results suggested that the total absence of color and shading may not be ...

The present case report clearly establishes nitrofurantoin as a cause for erythema nodosum (EN), presenting with serum sickness-like symptoms, typical and atypical EN skin lesions, and pseudo-splinter hemorrhages in a patient with documented mitral valve prolapse.

Temporal test-taking factors associated with the Rorschach white space response were investigated employing the individually administered protocols of 116 medical students. The temporal response rates of DS and DDS were examined separately against the response rate expectancies of D and DD, respectively. Response rates for both space response categories did ...

In an attempt to induce permanent aspermia the caudae epididymes of 17 bulls were subjected to ligation or injection with ethanolamine or chlorhexidine in dimethyl sulphoxide. Nylon and polyglycolic acid ligatures had little or no effect on the sperm counts although these materials were used in only three bulls. Steel ...

There is evidence to suggest that fusional vergence acts as a two-stage process consisting of fusion-initiating and fusion-sustaining components. The interrelationship of these components was examined by comparing the amplitude of disparity-induced vergence over the operating range of sustained fusional vergence. The results showed that as sustained convergence increased, disparity-induced ...

To find the specific chemical moiety responsible for the disaggregation of polyribosomes after induction of aberrant behavior by d-amphetamine, specific amine blockers and reserpine were utilized. It appears that dopamine is responsible for both the disaggregation of polyribosomes and stereotypic behavior while the roles of serotonin and norepinephrine are not ...

Studied the effects of aversive imagery gradation and muscular relaxation as procedural variables within desensitization by using (pre-vs. posttreatment) peripherally cued electrodermal responsivity as the dependent-variable measure of fear. There was no evidence that experimental desensitization or any of its procedural components yielded attenuated electrodermal responsivity to the peripheral fear ...

Photically evoked after-discharge (PhAD) bursting was examined in lightly restrained albino rats during habituation of a leg flexion response. The initial effect of iterative footshock (200 trials, 0.17 mA, 2.5 msec duration, separated by 1.0 sec) was to block PhAD bursting. As response habituation developed PhAD reappeared at reduced levels, ...

Tuberculous pericarditis is a rare but dangerous disease with a mortality of 20% to 40%. Early diagnosis and institution of appropriate therapy are critical, and open pericardial biopsy appears to be the most reliable diagnostic tool. Corticosteroids, in conjunction with antituberculous medication, are effective in suppressing the early granulomatous inflammatory ...

The effects of intradermally administered histamine H1- and H2-receptor antagonists on the cutaneous responses--redness, weal, flare and itch--induced by intradermal injection of histamine were studied in man. Weal and redness were studied after blockade of the axon reflex by local infiltration with lidocaine. All responses were significantly inhibited by the ...

The normal response to stress can be understood in terms of periods of outcry, denial, and intrusive thoughts leading to working-through to completion. The general physician who understands this pattern can assist the patient through the denial phase by encouraging ventilation and through the intrusive phase by providing structure, advice, ...

Mongolian gerbil (Meriones unguiculatus) readily attacks an unfamiliar gerbil intruding into its territory. After several attacks, subordinated intruders seldom scent-mark in the occupied area. This inhibition of scent-marking is a response to stimuli associated with the defended territory, since subordinated males mark normally elsewhere. Previous research suggested that olfactory cues ...

A quantitative assessment of post-ischaemic paraesthesiae has been made in 50 pellagrins and 20 healthy identical controls. The results show a higly significant diminution of the paraesthetic response in pellagrins. In pellagrins having peripheral neuropathy the depression of paraesthesiae was more marked than in those without peripheral neuropathy. There was ...

The reaction between endotoxic lipopolysaccharide (LPS) and the guinea pig complement system was shown to proceed by way of an intermediate complex, LPS-X, which contains at least six guinea pig serum proteins. LPS-X, like [unk] (sheep erythrocytes carrying antibody molecules and [unk] complexes), destroys the C3 molecule by cleavage. On ...

Oxygen isotopic comparisons of phenotypes of Recent Planktonic Foraminifera with both normal and diminutive final chambers are compatible with a model in which the latter develop as a response to environmental stress. Isotopic evidence shows that Spheroidinella dehiscens is probably not a late-stage, aberrant form of Globogerinoides sacculifer.

1. Isoprenaline injection into either the unanaesthetized ovine foetus or the pregnant ewe produced a transient tachycardia and hypotension in either the ewe or the foetus. No evidence was obtained for placental transfer, in either direction, of pharmacologically active isoprenaline.2. Propranolol, when given to the ewe intravenously, produced bradycardia and ...

Thesis (Ph.D.)--Medical College of Ohio, 2005.

The academic essay "The medical community's response to the cholera epidemic in London, 1831-1832" by Michael Jennings is available in full text from the online archives of Loyola University's Student Historical Journal. Published in 1994, the essay examines contemporary attitudes and reactions to the severe outbreak of cholera which decimated ...

Newly hatched ducklings were exposed to imprinting procedures and subsequently trained to peck a key by presenting the imprinting stimulus as the reinforcing (response-contingent) event. Individual ducklings then lived in the apparatus under an arrangement in which each peck produced a 15-sec stimulus presentation. For all ducklings, key-pecks tended to ...

Much more information is required on the distribution of blackflies in various parts of the world, and in many cases an adequate methodology for obtaining such information still has to be worked out. A detailed methodology for the collection of information about blackflies is given, which was developed for investigations ...

The performance maintained by reinforcing responses only when they terminated interresponse times (IRTs) of 20 sec or greater (DRL schedule) was almost the same during the first session of reconditioning as before extinction. As few as two reinforcements accurately reinstated both the pre-extinction rate of responding and the function relating ...

D-Tubocurarine (curare) and acetylcholine (ACh) had been found to block electrical activity after treatment of squid giant axons with cottonmouth moccasin venom at a concentration which had no effect on conduction. It has now been demonstrated that this effect is attributable to reduction of permeability barriers. The penetration of externally ...

A simple method has been described by which the action of drugs on the stress-induced block in milk ejection can be investigated on lactating guinea-pigs. Reserpine, meprobamate and chlorpromazine when administered to the lactating mother at various periods before suckling reduced the block in milk ejection caused by the stress. ...

Since the responses to "neurosympathomimetic amines" are reduced in the reserpinized animal and restored by norepinephrine administration, it was postulated that norepinephrine might also affect the development of their tachyphylaxis. We found that norepinephrine infusion restored, at least partially, certain tachyphylactic responses to amphetamine or ephedrine and fully prevented the ...

Pyelitis with acute and chronic pyelonephritis and also primary chronic pyelitis were easily initiated in female rats by a single non-traumatic retrograde infusion of bacteria into the urinary tract. The virulence of the bacterial species and the time of observation were related to the type and extent of lesions, but ...
