The front chamber of LUPRON DEPOT 3.75 mg prefilled dual-chamber syringe contains leuprolide acetate (3.75 mg), purified gelatin (0.65 mg), DL-lactic and glycolic acids copolymer (33.1 mg), and D-mannitol (6.6 mg). The second chamber of diluent contains carboxymethylcellulose sodium (5 mg), D-mannitol (50 mg), polysorbate 80 (1 mg), water for injection, USP, and glacial acetic acid, USP to cont...

The goal of this paper was to design several sodium carboxymethylcellulose hydrogels containing a BCS class II model drug and to evaluate their flow and thixotropic properties. The rheological measurements were performed at two temperatures (23 °C and 37 °C), using a rotational viscometer. The hydrogels were stirred at different time intervals (10 s, 2, 5, 10 and 20 min at 23 °C, and 10 s, 2 an...

Radiesse (Bioform Inc, USA) is a sterile, latex-free, non-pyrogenic, semi-solid, cohesive subdermal, injectable implant, whose principal component is synthetic calcium hydroxylapatite, a biocompatible material with over 20 years of use in medicine. The semi-solid nature of the product is created by suspending calcium hydroxylapatite microspheres of 25-45 microns diameter in a gel carrier of car...

Background The range of fillers currently available for soft-tissue augmentation is constantly expanding. The latest advances in filler technology include collagen biostimulators that exert their esthetic effect by promoting neocollagenesis. One such product is the next-generation collagen biostimulator (Ellansé®) that demonstrates properties as yet unseen in soft-tissue fillers. It is composed...

Ferritin from Reuber H-35 hepatomas was compared with ferritin from livers of ACI rats, the strain of rats in which the original H-35 hepatoma developed. The isoelectric points of these two proteins are 5.20 ±0.02 (H-35 ferritin) and 4.95 ±0.03 (ACI liver ferritin). The amino acid composition of apoferritin prepared from H-35 hepatoma ferritin differs significantly from that of ACI rat liver ...

A thermophilic strain AMF-07, hydrolyzing carboxymethylcellulose (CMC) was isolated from Kerman hot spring and was identified as Bacillus licheniformis based on 16S rRNA sequence homology. The carboxymethylcellulase (CMCase) enzyme produced by the B. licheniformis was purified by (NH4)2SO4 precipitation, ion exchange and gel filtration chromatography. The purified enzyme gave a single band on S...

Fibroblasts from patients with the Sanfilippo syndrome fall into two subgroups, each manifesting a deficiency of a specific factor required for normal metabolism of sulfated mucopolysaccharide. The factor deficient in the A subgroup has been purified 850-fold from normal human urine by ammonium sulfate precipitation, successive chromatography on Sephadex G-ZOO, carboxymethylcellulose, and hydro...

Aquacel Ag((R)) (ConvaTec, Princeton, NJ, USA) is a new hydrofiber wound dressing consisting of soft non-woven sodium carboxymethylcellulose fibers integrated with ionic silver. It is a moisture-retention dressing, which forms a gel on contact with wound fluid and has antimicrobial properties of ionic silver. We present a current literature review on Aquacel Ag((R)), of both in vitro and in viv...

This article describes a single-centre, non-comparative evaluation set out to assess the clinical performance and patient acceptability of a new carboxymethyl cellulose (CMC) wound dressing. Twenty patients in a community setting, aged between 34-97 years, were recruited. The progression of various types of wounds with different levels of exudate was documented over 4 weeks. No adherence to the...
