The aim of this report was to describe the computed tomography features of injected carboxymethylcellulose and how it can be mistaken for tumor recurrence. Carboxymethylcellulose is a low-density injectable indicated for short-term vocal fold augmentation. When used in patients with head and neck cancer, differentiating this agent from a neoplastic recurrence can be difficult on imaging. The im...

CONTEXT Endoscopic mucosal resection is an established modality for excision of sessile lesions in the gastrointestinal tract. Submucosal fluid injection creates a cushion and may prevent thermal injury and perforation. OBJECTIVES This blind study investigated the performance of three different solutions to create submucosal fluid cushions in porcine stomach. METHODS Three solutions were in...

Purpose: To compare the mucoadhesive performance of grewia polysaccharide gum with those of guar gum, carboxymethylcellulose, hydroxypropyl methylcellulose and carbopol 971P. Methods: Grewia polysaccharide gum compacts or gels as well as those of guar gum, carboxymethylcellulose, hydroxypropyl methylcellulose or carbopol 971P were prepared. Texturometric and tensile analysis of the polymer gels...

BACKGROUND To investigate the effectiveness of melatonin in preventing post-operative adhesion formation and to compare it with the efficacy of hyaluronate/carboxymethylcellulose membrane in a rat model. MATERIALS AND METHODS Following pilot studies, 35 rats were operated on in the full study. In 15 animals (group one), 10 standard lesions were inflicted in each uterine horn (total 30 horns) ...

PURPOSE From a quantitative point of view, to determine if the viscous friction forces could act as possible promoters of ocular stabilization keeping the rotational movements, which would provide the necessary values to be used in the ocular system. METHODS A mechanical model was created to measure the necessary forces to overcome the friction of an aluminum sphere partially kept in a viscou...

BACKGROUND To assess the anti-adhesive effect of treatment with hyaluronic acid-carboxymethylcellulose following laparoscopic radical prostatectomy. METHODS This was a randomized, controlled, single-blind, parallel-group study using hyaluronic acid-carboxymethylcellulose in patients who underwent laparoscopic radical prostatectomy. Sixty patients were enrolled in the study. All patients were ...

Killed BCG cells suspended in 1.5% carboxymethylcellulose cured guinea pigs with established line 10 tumors in a high percentage of cases. The bacterial preparation of BCG in carboxymethylcellulose displayed a stronger tumor regressive activity and the process of healing was accelerated when endotoxin from a rough (Re) strain of Salmonella typhimurium was added to the BCG bacilli.

Introduction: Idiopathic pulmonary fibrosis (IPF) is a relentlessly progressive and usually fatal lung disease of unknown etiology for which no effective treatments currently exist. In the adults type I and II pneumocytes, forms Components of the alveolar epithelial cells. In this study, we investigated the effect of thalidomide on the alveolar epithelial cells (type I and II pneumocytes) in ...

The concentrations of homogenate-nitrogen, of DNA, and the activities of various nucleotidases, adenosine deaminase, cathepsin and lactic dehydrogenase have been studied in homogenates of Sarcoma 180 from non treated mice, from mice given injec tions of 6-carboxymethylcellulose in saline, and from mice treated with 6-mercaptopurine suspended in saline containing 6-carboxymethylcellulose. Statis...

The rheological behavioral changes that occurred during the synthesis of an interpolyelectrolyte complex (IPEC) of methacrylate copolymer and sodium carboxymethylcellulose were assessed. These changes were compared with the rheological behavior of the individual polymers employing basic viscosity, yield stress, stress sweep, frequency sweep, temperature ramp as well as creep and recovery testin...
