A procedure has been detailed for the preparation of sterile non-pyrogenic solutions of oxyhemoglobin which have the approximate protein content and electrolyte composition of plasma. Large volumes of solution can be rapidly prepared, with 95 to 98 per cent of the hemoglobin in the active form capable of combining with oxygen. The solutions contain no particulate matter; 95 per cent of total bl...

Introduction: antimicrobial activity of irrigants and interappointment intracanal dressing is an important consideration in endodontics . The aim of this study was to evaluate the clinical efficacy of chemomechanical preparation of the necrotic canals with different irrigants and intra canal dressing in the control of root canal infection and sinus tract closure. Materials &Methods: In this ...

The percutaneous absorption of local anaesthetics in a standard formulation has been compared in vitro and in vivo. In vitro data were obtained with a modified Sartorius absorption system and silastic as a lipophilic barrier membrane. With this system the greatest steady-state flux values and permeability coefficients were obtained with amethocaine and lignocaine. These drugs also performed bes...

This article describes a method by which about a hundred mCi of different radiopharmaceuticals (imipramine, chlorpromazine, nicotine or methionine) may be prepared in 3(t35 min with no irradiation risk to the operators, All operations (preparation of precursor. methylation of the monodesmethyl derivative, purification and sterilisation of the end product) are carried out in a closed shielded ho...

Outcome Number of studies Odds ratio Confidence interval (95% confidence level) Reduction in Needle Sharing 6 3.22 2.17-4.77 Needle and Syringe Programs (NSPs) are interventions that provide drug preparation and injection equipment to injection drug users to decrease equipment sharing, and consequently, HIV transmission risk. Drug equipment may include needles, syringes, and other ancillary mat...

Preparation • Dissolve 1 heaped teaspoonful of salt or sodium bicarbonate in a jug containing 500 ml of boiled water (half a litre); allow this solution to cool (Figure 1). • Pour a very small amount of the solution into a small sterile pot on a clean surface (Figure 2). Method 1 The eyelashes • Ask the patient to close both eyes. • Take a folded gauze swab or cotton bud. • Moisten the swab or ...

The regulations set forth by the United States Pharmacopeia (USP) Chapter <797>, in effect since January 1 of 2004, have generated a great deal of interest because they have established the first practice standards of sterile pharmacy compounding in US history that are enforceable at both the federal and state levels. United States Pharmacopeia Chapter <797> expands the scope of facilities gove...

Casbene is a macrocyclic diterpene hydrocarbon that is produced in young castor bean (Ricinus communis L.) seedlings after they are exposed to Rhizopus stolonifer or other fungi. The activities of enzymes that participate in casbene biosynthesis were measured in cell-free extracts of 67-hour castor bean seedlings (a) that had been exposed to R. stolonifer spores 18 hours prior to the preparatio...
