Effective assessment and management of wound pain can facilitate both improvements in healing rates and overall quality of life. From a pharmacological perspective, topical application of nonsteroidal anti-inflammatory drugs in the form of film wound dressings may be a good choice. Thus, the aim of this work was to develop novel layered film wound dressings containing ibuprofen based on partial...

Crystalline turkey egg white lysozyme has been prepared by a simple procedure consisting of adsorption on carboxymethylcellulose followed by elution with (NH4)&03 solution and crystallization from 5 % NaCl solution. The twice crystallized enzyme gave a single peak when eluted from carboxymethylcellulose, and it migrated as a single band during disc electrophoresis. Separation of the tryptic pep...

Stress development during drying of coatings produced from aqueous dispersions of calcium carbonate particles in the presence and absence of organic binders was studied using a controlled-environment stress apparatus that simultaneously monitored drying stress, weight loss, and relative humidity. Specifically, the influence of two organic binders on drying stress evolution was investigated: (1)...

The transport of microscale carbonyl iron powder suspensions modified with anionic homopolymers was studied in water-saturated sand columns containing well-dispersed hydrophobic sand grains. Sand grains functionalized with hexadecyltrimethoxysilane were coated with a eutectic mixture of dichlorobenzenes that was solid at -10 °C and was mixed by grinding with unmodified sand grains. The dichloro...

OBJECTIVE To determine the efficacy of adhesion barriers in horses using quantitative statistical analysis. STUDY DESIGN Meta-analytical review. METHODS A search using PubMed/MEDLINE and Google Scholar was performed, followed by secondary searches of veterinary trade journals, bibliographies of relevant articles, manufacturer websites, and technical reference guides. Randomized experimental...

The usual methods for prenatal diagnosis of beta-thalassemia and other hemoglobinopathies by assay of fetal blood erythrocytes are either complex (analysis of globin chains synthesis by carboxymethylcellulose chromatography) or only semiquantitative [isoelectric focusing of hemoglobin (Hb)]. To further simplify the diagnostic procedure and to obtain quantitative data, we measured the small conc...

Enalapril maleate is used in the treatment of hypertension and angina pectoris. It shows low bioavailability due to high hepatic first pass metabolism. Hence the present work was undertaken to formulate mucoadhesive buccal films of enalapril maleate with an objective to improve therapeutic efficacy, patient compliance and the bioavailability. In the present study ten formulations of mucoadhesiv...

PURPOSE The aim of this study was to prepare the optimized oral paste formulation of Triamcinolone acetonide intended to be used in aphtous stomatitis. METHODS Plastibases were prepared using mineral oil and polyethylene (95:5). Oral paste formulations were prepared with different mixtures of three hydrocolloids solids, including gelatin, pectin and sodium carboxymethylcellulose, with differe...

The local delivery of antibiotics in the treatment of infectious respiratory diseases is an attractive alternative to deliver high concentration of antimicrobials directly to the lungs and minimize systemic side effects. In this study, inhalable microparticles containing doxycycline hyclate, sodium carboxymethylcellulose, leucine and lactose were prepared by spray drying of aqueous ethanol form...

AIM To assess the efficacy of sodium carboxymethylcellulose in the treatment of dry eye. MATERIAL AND METHODS We carried out a prospective, randomized, masked-observer, control/problem group, single-center clinical assay during a period of 12 months in 19 patients that presented mild or moderate forms of dry eye. Patients were clinically evaluated each 3 months and treated with a 0.5% isotoni...
