Rapid Method of removing Plaster

Method for removing hypopharyngeal salivary bypass tubes.

OBJECTIVE To describe a novel method for the removal of the salivary bypass tube (SBT) that precludes the need for extraction under general anesthesia. STUDY DESIGN Retrospective case series. METHODS/TECHNIQUE Patients who had undergone laryngectomy/laryngopharyngectomy with subsequent development of pharyngocutaneous fistula and intraoperative placement of a salivary bypass tube were inclu...

Plaster of Paris

Paris (CaS04)2H20. Excessive heat convey it into anhydrous calcium sulphate CaB^< which takes up water very slowly and does D?. harden and set. 2CaS04.2H20 = (CaSW 2H20+3H20. (CaS04)2H20 = 2CaS 04H2U, Commercial plaster of Paris is manufacture from impure gypsum and therefore contains tn impurities present in the gypsum such as alum10^ iron, silicates, carbonates, lime, etc., which be recognize...

A REPORT OF RAPID AND EFFICIENT METHOD FOR MITOCHONDRIAL DNA

Based on the similarity of prokaryotic DNA to that of mitochondrial DNA, a rapid and efficient method for DNA purification from mitochondrial extracts obtained from different sources, was carried out based on the modification method described by Marmur (1983) which resulted in a high degree of purity (A260/A280=2). In addition we have applied the same technique for the first time to purify...

Rapid measurement of soil water by gravimetric method

A rapid chemical means for removing labile glycohemoglobin.

We have devised a rapid and convenient method of eliminating the contribution of labile glycosylated hemoglobin in the hemoglobin A1 assay. The procedure requires a 30-min incubation of erythrocytes in 30 mM semicarbazide and 12 mM aniline (pH 5, 38 degrees C). This chemical means of eliminating the labile fraction is as effective as a 14-h incubation in isotonic saline as measured with high-pr...
