Two monofilament suture-materials that recently introduced, Polydioxanone (PDS II,7-0, Ethicon) and Polyglyconate (Maxon CV, 7-0, Davis Geek) have been represented as low reactivity absorbable alternatives, 22 arterio-venous side-to-side anstomoses using those surgical threads were performed at upper extremity for patients requiring a permanent vascular access for chronic hemodialysis, 14 of …
A potassium bromide pellet method in the infrared spectroscopy has been studied to analyze the metastable polymorph of chloramphenicol palmitate quantitativity. By minimizing of the milling time by vibrating mill under the 5 tons of the pellet compression, the transition process of chloramphenicol palmitate crystal form could be avoided. Through the selection of the two peak absorbance ratio of…
The aims of this study were to find out formulas of granules made from complexes drugs-shellac resin that has constant release pattern. The influence of pH on the drugs release was also investigated. The drug-shellac resin complex was made by dispersing disclofenac sodium into alcoholic solution of shellac. Three different ratios of the drug-shellac resin (1:5; 1:3; 1:1) respectively were made.…
