Control and dispositional style among the hearing-impaired in communication situations.

Forty hearing-impaired subjects were exposed to three stressful communication situations in a laboratory setting. The communication patterns used and the extent to which the subjects succeeded in coping with the situations were studied. Measures, such as the life orientation test measuring dispositional style, a hearing questionnaire measuring the ability to cope with different hearing situations, degree of control and pure-tone audiometry were performed.

Behavioral counselling for subjects with acquired hearing loss. A new approach to hearing tactics.

Effects of behavioral counselling of subjects with an acquired hearing loss were evaluated in an experimental design. The study included a group of 20 hearing-impaired subjects who were assessed and randomly allocated to a treatment or control group. Behavioural counselling, individualized according to the results of functional analysis, was then given to 10 subjects and included the teaching of 'hearing tactics'.

A behavioural approach to individually designed hearing tactics training.

In an experimental study involving 20 subjects functional consequences of hearing disability were assessed and counselled in accordance with behavioural principles. The aims were to develop psychological methods for analysing and relieving hearing problems. The results indicated that treated subjects improved significantly in three functional areas as compared to controls.

Atelectasis and lung function in the postoperative period.

Thirteen patients with healthy hearts and lungs, and with a mean age of 68 years, who were scheduled for lower abdominal surgery during isoflurane anaesthesia with muscular paralysis, were investigated with arterial blood gases, spirometry, pulmonary x-ray and computed tomography (CT) of the chest before and during anaesthesia, as well as during the first 4 postoperative days. Before anaesthesia, lung function and gas exchange were normal in all patients. Pulmonary x-ray and CT scans of the lungs were also normal.

Selenium status of patients with Balkan endemic nephropathy.

The selenium (Se) contents in common cereals in endemic and nonendemic areas in Serbia are very low. Plasma Se levels of both patients and healthy subjects, were also low, reflecting low Se intakes. Patients with Balkan endemic nephropathy (BEN) had significantly lower (p less than 0.

Accidental selenium poisoning of growing pigs.

Chronic selenium (Se) toxicosis was diagnosed in two groups of growing pigs. Emaciation, loss of hair, necrotic areas in the skin, lesions of the coronary band and hooves, postnecrotic atrophic cirrhosis of liver, and lumbal poliomyelomalacia were the principal findings. High Se concentrations were detected in blood plasma.

A new experimental model for studies of local inflammatory reactions.

The aim of the present study was to develop and evaluate a method for studies of the early phase of the local inflammatory reaction, based on continuous diffusion of an inflammatory inducing agent. 25 rats were used. Four sterile teflon tablets were implanted subcutaneously in the back of each animal.

Resolution of the enantiomers of omeprazole and some of its analogues by liquid chromatography on a trisphenylcarbamoylcellulose-based stationary phase. The effect of the enantiomers of omeprazole on gastric glands.

The enantiomers of omeprazole and some of its analogues have been separated on a chiral stationary phase comprising trisphenylcarbamoylcellulose coated on 3-aminopropyl silica. The nature of the supporting silica has a crucial effect on the separations obtained. The racemisation half-life of omeprazole was estimated to be 1.

Utilization of dietary sodium selenite, barley, oats and meat meal selenium by the chick.

The biological availability of selenium (Se) in barley, oats and meat meal as compared to that in sodium selenite was determined by whole blood glutathione peroxidase (GSH-Px) activity and Se concentration depletion-repletion bioassays. One day old White Leghorn chicks, initially of low-Se status, were further depleted for Se by feeding a low-Se casein basal diet (0.03 mg Se/kg diet) adequate in vitamin E for the first two weeks of life.

Predictors of tinnitus discomfort, adaptation and subjective loudness.

In a nation-wide investigation, covering all the hearing centres in Sweden, a study was made of adaptation processes, subjective discomfort from tinnitus, subjective loudness of tinnitus and psychological complaints in 3372 subjects by means of a questionnaire. The most important predictors of discomfort from and adaptation to tinnitus were found to be the controllability and the degree of maskability by external sounds, i.e.
