OBJECTIVE The objective of this study was to evaluate in an analytical and descriptive manner the evidence published so far on the use of polyethylene glycol (PEG), with or without electrolytes, in the management of functional constipation and the treatment of fecal impaction. METHODOLOGY Search on MEDLINE, EMBASE and Cochrane databases until May 2016 of all publications adjusted to the follo...

environmental stresses specially drought, play an important role in decreasing plant growth, particularly during germination in dry and semi dry area. to considering the effect of drought stress caused by polyethylene glycol on germination and characteristics of 2 spices of sesamum indicum, we had done factorial and complete accidental plot with 4 treatments and 3 times repetition. experimental...

physiological effect of five levels of water stress (0,-0.3,-6,-9 and -1.2mp) was studied on seed germination and tigella as well as radicule growth length in two different artemisia species namely: artemisia spicigera and artemisia fragrans. polyethylene glycol (peg) was used to provide appropriate water potentials. a total of 50 seeds were sown from each artemisia species. experimental design...

the aim of me present work was to investigate rhe potential utility of nanoparticles made of chitosan (cs) and also cs chemically modified with polyethylene glycol (cs-peg) as new vehicles for improving na^al vaccine delivery. for mis purpose, diphtheria toxoid (dt) was chosen as a model antigen. dt was entrapped within nanoparticles made of cs of different molecular weight, and also made of cs...

1. The effect of iodination on the distribution of peptide hormones into the aqueous two-phase dextran-polyethylene glycol system and on the solubility of these hormones in aqueous polyethylene glycol and in water was assessed. Hormones that were studied included insulin, glucagon and parathyroid hormone. 2. The partition coefficient of native insulin in the dextran-polyethylene glycol system s...

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...
