BACKGROUND In bronchial asthma, inflammatory cells infiltrating the airway mucosa release oxygen radicals that cause tissue damage and amplify the airway inflammation. Antioxidant enzymes may have a protective effect on the airways. OBJECTIVE The purpose of this study was to determine whether treatment of a rabbit model of chronic allergic asthma with the antioxidant enzyme superoxide dismuta...
BACKGROUND: Constipation is one of the common problems in childhood and consists of 3% of referrals to pediatricians and 25% of pediatric gastroenterologists. Aperients are common alternatives for treating chronic constipation. The present study aimed to compare the efficacy of three laxatives [polyethylene glycol (PEG), magnesium hydroxide, and lactulose]. METHODS: In this randomized clinical ...
BACKGROUND Constipation is a common clinical problem. Lactulose and Polyethylene Glycol (PEG) are both commonly used osmotic laxatives that have been shown to be effective and safe treatments for chronic constipation. However, there is no definitive data as to which provides the best treatment. OBJECTIVES To identify and review all relevant data in order to determine whether Lactulose or Poly...
BACKGROUND Several studies with erythropoiesis-stimulating agents claim that maintenance therapy of renal anaemia may be possible at extended dosing intervals; however, few studies were randomized, results varied, and comparisons between agents were absent. We report results of a multi-national, randomized, prospective trial comparing haemoglobin maintenance with methoxy polyethylene glycol-epo...
A new analytical method has been developed for the quantitative determination of ethylene glycol-containing nonionic surfactants, such as polyethylene glycol 8000, polysorbate 80, and Pluronic F-68. These surfactants are commonly used in pharmaceutical protein preparations, thus, testing in the presence of protein is required. This method is based on the capillary gas chromatographic analysis o...
A strictly anaerobic, homoacetogenic bacterium was enriched and isolated from anoxic sewage sludge with polyethylene glycol (PEG) 1000 as sole source of carbon and energy, and was assigned to the genus Acetobacterium on the basis of morphological and physiological properties. The new isolate fermented ethylene glycol and PEG's with molecular masses of 106 to 1000 to acetate and small amounts of...
in this study, physiological and morphological responses of five almond cultivars to drought stress were investigated under in vitro conditions. plantlets from five commercial almond cultivars (supernova’, ‘tuono’, ‘sahand’, ‘ferragnes ’ and ‘shahroud 21’] were established in ms medium containing 0.5 mg per liter bap and then subcultured in ms proliferation medium containing 1 mg per liter bap...
introduction: macroprolactin is a significant cause of misdiagnosis, unnecessary investigation, and inappropriate treatment in patients with hyperprolactinemia. its frequency has not been clearly established due to technical difficulties in identifying it. most laboratories and clinicians are unaware of macroprolactin interferences in prolactin assays. materials and methods: a comprehensive lit...
