In the management of intoxications, the major goals are enhanced elimination of the toxin from the organism and prevention of further absorption. Absorption of an orally administered substance from the gastrointestinal tract can be decreased by adequate washing of the stomach. Delayed absorption of the substance from the small intestine ...

Since 1970 there have been many changes in our knowledge of premature rupture of the membranes (PROM). Studies of its causes have focused on clinical variables, physical properties of the membranes, and subclinical infection, while new diagnostic techniques have included biochemical and histochemical tests, as well as intrauterine dye injection. ...

Recruitment of participants to a multicenter study is complex. Considerable attention must be given to management and organization. In either a multi- or single-center study, a data-based management system is a sensitive and responsive means of monitoring participant flow. This system gives rapid feedback, encourages ongoing evaluation of strategies and ...

Ten patients were included in this pilot study of chlormezanone, assessing its effects on duration and quantity of sleep and daytime performance using a pursuit rotor and a digit symbol test.

Under the conditions of this study, crowns made from Coldpac had marginal discrepancies approximately four times larger than those made from Scutan. ...

Cryomethods were used in order to investigate the ultrastructure of native elastin fibres from beef ligamentum nuchae. Filaments of diameter 5 nm, running almost in parallel in purified, negatively-stained elastin preparations, were also seen running along the elastin fibre both in freeze-fractured and etched elastin, that had been stretched up ...

Insecticido-repellent mixtures sprayed on clothes, nets etc. are useful as a means of protection against attack by bloodsucking arthropods. These sprays provide repellence of insects sensitive to the repellent and kill those that are only weakly repellent sensitive. Combined formulae for aerosols including repellent DETA and the synthetic pyrethroid neopynamin ...

Aphasic individuals have a tendency to decode past tense and future tense sentences as if the sentences were in the present tense. This study assessed the influence of additional surface structure markers of past or future tense this comprehension process. The results indicated that additional markers significantly facilitate the comprehension ...

An 11-year-old boy underwent resection of an abnormally draining ureteral segment of a retrocaval right ureter. Compression by the inferior vena cava may have caused the faulty drainage. End-to-end ureteroureteral anastomosis was carried out. Intraoperative study of perfusion was helpful in the management of this child's condition.

Studies were conducted to evaluate uterine motility and fertility of ova in ewes either given or not given supplemental selenium/vitamin E (SSE or NSE, respectively). The ewes were maintained on either an adequate plane of nutrition (APN) or an inadequate plane of nutrition (IPN). In a fertility study, 60 ewes ...

An absorbable lublicating coating applied to Vicryl sutures has improved the ease with which the sutures pass through tissue and has made handling and tying better. The coated sutures were found to be safe, strong and secure. No disadvantages were seen as a result of coating the synthetic absorbable Vicryl ...

When grazing is the accepted land use, vegetation is the key resource. The present study deals with the desert shrub rangelands of lraq, which contain the major characteristics of such an area, having been under grazing for many centuries. Emphasis is given to the ecology and utilization of the vegetation ...

In Fijian, matiruku means literally 'low tide in the morning' and figuratively somebody periodically insane. In this study, the conceptual basis of matiruku was examined by means of a questionnaire completed by 24 Fijians which explored its occurrence, aetiology and precipitation, phenomenology, management and prognosis.

Significant gametic association was observed for (A1, Bw17), (A2, B27), (Aw26, Bw16), (Aw19, B13) and (A28, B14). Although a predominantly Caucasoid ...

Hyperandrogenism is a common endocrinopathy in women. Localization of the source of excess androgen production is mandatory for proper management. Ovarian hyperandrogenism has been implicated in the majority of patients studied, though the true prevalence of adrenal hyperandrogenism is not yet known. Adrenal scintigraphy is a simple non-invasive technique which ...

Previous studies have shown that subjects could acquire a prismatic aftereffect contingent on the direction of gaze. Other studies have shown that subjects could acquire two simultaneous aftereffects with multiple cues. In the present study 12 subjects practiced alternately under two opposite 20-diopter lateral displacements and displayed two gaze-contingent aftereffects.

In a prolonged field trial a 4% chlorhexidine digluconate detergent scrub (Hibiscrub(R)), that had earlier proved to be an effective hand disinfectant, was studied in hospital wards. Finger tips were found to harbour more bacteria than the hand dorsum and the samples collected from them yielded more information on the ...

A biochemical approach was used to study the evolution of ratite birds, i.e., the ostriches, rheas, cassowaries, emus, and kiwis. Quantitative immunological comparison of transferrin from ratites, tinamous, and other flying birds indicates that all the ratites and tinamous are allied phylogenetically and that they are of monophyletic origin relative ...

1. The interaction between the reversible cholinesterase inhibitors, physostigmine and neostigmine and reserpine was studied. 2. A combination of reserpine plus a cholinesterase inhibitor significantly increased lethality in adult male Swiss-Webster mice above that caused by either neostigmine, physostigmine, or reserpine alone. 3. Methscopolamine completely reversed this effect. 4. It ...

Low input methods of establishment including the use of tree shelters and the tending and thinning of younger oak stands together with control ...

Twenty-three patients were seen with entrapment neuropathy in a two-and-a-half-year period. Symptoms consisted of pain, paresis, and paraesthesia in the distribution of the common peroneal nerve. Some degree of paresis was often present, which in five patients was severe enough to cause drop foot. In 20 patients decompression of the ...

Particulate mucopeptides of Group A-variant streptococci and Staphylococcus aureus, solubilized by ultrasonic treatment, give a precipitin reaction with the sera of rabbits immunized with Group A-variant streptococci. gamma-G globulin antibodies have been recovered from these sera which react with the mucopeptides but not with the Group A-variant carbohydrate. The immunochemical ...

To determine whether the factor(s) responsible for the conservation of epidermal specificities in adult guinea pigs and hamsters resides in the germinal layer of the epidermis or in the dermis, thin grafts of skin, possessing qualitatively distinct regional characteristics, were separated into their superficial epidermal and dermal components with the ...

In their practice of medicine, clinicians occasionally encounter patients with eosinophilia in which the common causes have been satisfactorily ruled out. It is the purpose of this review to present some of the salient features of our present knowledge concerning the eosinophil and to suggest a method for studying eosinophilias ...

In the polytene chromosomes of Sciara coprophila, in addition to a nucleolus, large numbers of nucleolarlike structures or micronucleoli are formed. A detailed mapping localized the nucleolar organizer at one end of the X chromosome and revealed that approximately 18% of the bands of each chromosome are potentially capable of ...

This paper constitutes a report on mammalian toxicological investigations of fen hion, carried out as part of the WHO malaria eradication programme, and on the conclusions drawn from them. Fenthion is found to be of intermediate toxicity to the four rodent species studied. In rats the signs of poisoning develop ...

Although various hypotheses have been put out as to the etiology of amyotrophic lateral sclerosis, they do not seem to date to have been substantiated by experimental evidence. As the incidental outcome of studies on possible carcinogenic processes, the authors of this paper have obtained experimental data indicating the possibility ...

Entire hydras or tentacles were prepared for electron microscopy as described in the preceding paper. The stenotele capsule has been observed to be composed of an external membrane, a thick chitinous or keratin layer, and an inner membrane. A sac-like extension of the capsular wall into the capsule bears spines ...
