Serum lysozyme activities and semiquantitative analysis of tissue lysozyme distribution were studied in patients with primary biliary cirrhosis (PBC), chronic hepatitis (CH), miscellaneous liver diseases, and normal subjects. Serum lysozyme was significantly raised in PBC and CH. Portal venous blood has similar lysozyme activities to peripheral venous blood in a group of various liver diseases....

the interaction between nano-sio2 and lysozyme was investigated by the method of uv-visible  detection and fluorescence spectroscopic techniques. the thermal denaturation of lysozyme has been investigated in the presence and absence of nano-sio2 over the temperature range (293-373) k in different buffers and ph values, using temperature scanning spectroscopy. the presence of nano-sio2 caused th...

The complexation of lysozyme and sodium (sulfamate carboxylate) isoprene/ethylene oxide (SCIEO) at pH = 7.4 and the release of lysozyme from the complexes in the presence of NaCl were investigated. Through electrostatic and hydrophobic interactions, lysozyme and SCIEO form stable complex nanoparticles. The complexation partially disturbs the structure of lysozyme. Some of the hydrophobic residu...

Lysozyme is a protein found in egg white, tears, saliva, and other secretions. As a marketable natural alternative to preservatives, lysozyme can act as a natural antibiotic. In this study, we have isolated Bacillus licheniformis TIB320 from soil, which contains a lysozyme gene with various features. We have cloned and expressed the lysozyme in E. coli. The antimicrobial activity of the lysozym...

Mucoadhesive buccal tablets containing ondansetron hydrochloride (ODH) were prepared using polymers like gelatin, chitosan, xanthan gum in varying concentration of 5, 10, 15% w/w and HPMC K4M 40% w/w by direct compression technique. Precompressional studies revealed good micromeritic properties of powder blend for compression and were found as per literature limits. The prepared tablets were ev...

Recent work has shown the beneficial effects of a proprietary mixture of three non-digestible carbohydrates: konjac glucomannan, xanthan and alginate and these effects have been linked with a synergistic interaction observable with analytical ultracentrifugation, rheological and NMR measurements. These observations have been supported by fundamental dilute solution viscosity studies. Preparatio...

PURPOSE The aim of this study was to investigate the effects of an ophthalmic gel containing sodium hyaluronate and xanthan gum in addition to the antibiotic netilmicin in the management of traumatic corneal abrasions. PATIENTS AND METHODS PATIENTS WITH TRAUMATIC CORNEAL ABRASIONS WERE RANDOMLY TREATED AS FOLLOWS: Group A (n = 20) with an occlusive patching for 12 hours plus one drop of an ey...

The purpose of this research was to develop gastro-retentive delivery system of atenolol which, after oral administration should have the ability to prolong gastric residence time with desired in vitro release profile. Atenolol was chosen as a model drug because it is poorly absorbed from the lower gastrointestinal tract. The tablets were prepared by direct compression technique, using natural ...

The aim of the present study is to investigate the effect of Ammonio Methacrylate Copolymer Type B (Eudragit RS 30 D) on the release kinetics study of diclofenac sodium form coated pellets. The effect of the incorporation of xanthan gum into the coating formulation was also the goal of this study. Eudragit RS 30 D and xanthan gum was added into the formulation at 5:1 ratio. Different percent of...

σ factors provide RNA polymerase with promoter specificity in bacteria. Some σ factors require activation in order to interact with RNA polymerase and transcribe target genes. The Extra-Cytoplasmic Function (ECF) σ factor, σV, is encoded by several Gram-positive bacteria and is specifically activated by lysozyme. This activation requires the proteolytic destruction of the anti-σ factor RsiV via...
