Abstract The aim of this study was to compare the postural load during VDU work in following postures: (1) Supporting and not supporting forearms on table top, (2) Sitting standing positons, (3) Sightline centre screen at an angle 15 30 below horizontal. muscle from upper part musculus trapezius lumbar erector spinae (L3 level) measured by electromyography (EMG). Postural angles head, arm back were inclinometers. m. when using keyboard significantly less sitting with supported compared...

ABSTRACT Fifty recurrent stone formers were included in a double‐blind randomized study (median 3 years) performed Norwegian general practice to compare twice daily administration of 25 mg hydrochlorothiazide versus placebo. The number patients with new stones was significantly higher the placebo group than thiazide ( p =0.05, one‐tailed test). If formed, thiazide, but not placebo, had effect prolonging stone‐free interval ≤0.01). probability forming during treatment period 45% for and 75%...

The primary objective of this study was to investigate if supplementary lactobacilli treatment could improve the initial cure rate after vaginal clindamycin therapy, and secondly, as repeated adjunct during 3 menstrual cycles lengthen time relapse cure. Women (n = 100) with bacterial vaginosis diagnosed by Amsel criteria were informed consent offered therapy followed gelatine capsules containing either 109 freeze-dried or identical placebo for 10 days in a double-blind, randomized,...

<b>Background:</b> Dietary calcium and antioxidants have been suggested as protective agents against colorectal cancer. This has supported by animal experimental studies, case control cohort studies. <b>Materials Methods:</b> In a prospective intervention study of adenomas, intermediary stage in carcinogenesis, 116 polyp-bearing patients received placebo-controlled daily mixture β-carotene 15 mg, vitamin C 150 E 75 selenium 101 µg, (1.6 g daily) carbonate for period 3...

Normal sexual development and subsequent reproductive function are dependent on appropriate testosterone production action. The regulation of steroid hormones, including androgens, can be influenced by both biological environmental factors, chemicals. Concentrations organochlorines considerably greater in Svalbard polar bears than from other regions. Between 1995 1998, samples were collected 121 male (Ursus maritimus) the area. In this study, concentration variations described for during...

This study was undertaken to assess if high levels of organochlorines (OCs) are associated with decreased ability produce antibodies in free-ranging polar bears (Ursus maritimus) and thus affect the humoral immunity. In 1998 1999, 26 30 from Svalbard, Norway, Churchill, Canada, respectively, were recaptured 32–40 d following immunization inactivated influenza virus, reovirus, herpes virus tetanus toxoid. Blood sampled at recapture for determination plasma polychlorinated biphenyls (PCBs)...

Since the polar bear (Ursus maritimus) is among most highly organochlorine-contaminated species of Arctic mammals, there growing concern that in addition to natural stressors bear's environment, several organochlorines (OCs) may be able change basic endocrine pathways. Alterations hypothalamic-pituitary-adrenal (HPA) axis affect plasma cortisol concentrations and inhibit physiological processes involved maintenance homeostasis a way endanger animal's health. Between 1995 1998, samples were...

Epidemiological studies have suggested an association between diet and colorectal cancer. Case/control studies, however, been scarce, based on interview with cancer patients who symptoms from their are inevitably prone to bias. An endoscopic population screening study for detection of adenomas enabled a double-blind registration during 5 consecutive weekdays. Neither the participant nor dietitian was informed findings at endoscopy. The estimation 23 nutritional components analysis local...

AbstractPrevious studies have reported alarmingly high levels of organochlorines (OCs), particularly polychlorinated biphenyls (PCBs), in free-ranging polar bears (Ursus maritimus). In this study plasma concentration PCBs ranged from 14.8 to 200 ng/g wet weight. The aim the was investigate associations between OCs and lymphocyte proliferation after vitro stimulation with different mitogens antigens. 1998 1999, 26 30 Svalbard Churchill, Canada, respectively, were recaptured 32–40 d following...

The design of a population screening study, including endoscopic for polyps in the rectum and sigmoid colon, was tested denned sample 200 women men aged 50-59 years. attendance rate 81%. A simple bowel cleansing procedure performed immediately before examination gave satisfactory conditions 94% attendants. Polyp prevalence 35%. present material results represent basis further follow-up studies risk factors development cancer same group individuals.

Endoscopic findings are essential in evaluating the disease activity ulcerative colitis. The aim of this study was to evaluate how endoscopists assess individual endoscopic features mucosal inflammation colitis, inter-observer agreement, and importance observers' experience. Five video clips colitis were shown a group experienced inexperienced endoscopists. Both groups asked eight overall on visual analogue scale. following statistical analyses used; Contingency tables analysis, kappa...

Several studies indicate a causal relationship between duodenal diverticula and gallstone disease. The persist after biliary tract surgery, it is therefore presumed that patients with have an increased disposition to develop new calculi in the bile ducts cholecystectomy. To test this hypothesis, occurrence of recurrent was studied 101 who had cholecystectomy, all asymptomatic period two years or more following primary surgery. All symptoms, indicated pancreatic diseases. incidence 87.5% (95%...

Abstract The aim was to evaluate the performance of selected individual major histocompatibility complex (MHC) class I and II alleles combinations these on disease resistance against furunculosis. material, consisting 2,145 Atlantic salmon ( Salmo salar ) from seven families, contained four MHC (UBA) two alpha (DAA) alleles. included were previously shown influence towards fish challenged with bacterium Aeromonas salmonicidae , causing total mortality in material 84.0%, both dead surviving...

It is commonly believed that young calves should not be fed more than about 2l of milk per meal. If are beyond this volume, it said the capacity abomasum may exceeded and could enter rumen. This can disturb microbial flora/fauna rumen increase risk indigestion, diarrhoea reduced growth. The aim study was to examine effect large meals on digestive physiology behaviour in dairy calves. Six (19-23days age at beginning experiment) were warm whole by teat bottle three times day, which recommended...

AbstractWe studied the gastrointestinal side effects of three formulations naproxen in 18 healthy male volunteers. In a Latin-square design crossover study, subjects received 500 mg twice daily for 7 days as plain tablets, enteric-coated or granules capsules. The 51Cr-EDTA absorption test was performed before and at end each drug period, to evaluate changes distal gut. dose instilled distally duodenum prevent lesions stomach from interfering with evaluation. Upper endoscopy same intervals,...

An open, block randomised multi-centre clinical trial was performed in Norway during 1985 to 1987 compare the therapeutic efficacy of three antibiotic regimens against bovine mastitis caused by penicillin-sensitive bacteria. Two consisted procaine penicillin injected intramuscularly for either or five days, and third, traditional Norwegian regimen, one intramuscular injection a combination dihydrostreptomycin followed intramammary treatment daily per infected quarter four days. The study...
