An Apparatus for the Distribution of Antigen Emulsion in the Kahn Test
نویسندگان
چکیده
(King Institute of Preventive Medicine, Guindy) For testing every sample of blood the Kahn antigen emulsion has to be distributed in three varying volumes with the Kahn pipette. When a number of tests have to be performed, the time, labour and eye-strain involved in carefully transferring the antigen emulsion to the bottom of each tube are factors which require to be considered. The Kahn antigen emulsion does not remain homogeneous; when kept for more than a minute

Quantum dots of CdS synthesized by micro-emulsion under ultrasound: size distribution and growth kinetics
Quantum dots of CdS with hexagonal phase were prepared at relatively low temperature (60 oC) and short time by micro-emulsion (O/W) under ultrasound. This study was focused on the particle size distribution and the growth kinetics. The particle size distribution obtained from the optical absorption edge. It was relatively symmetrical with sonication time. In addition, an agreement was observed ...
متن کاملPreparation and Evaluation of Diphtheria Toxoid-Containing Microspheres
Preparation of chitosan (CS) microspheres as a novel drug delivery vehicle for intranasal immunization using high, medium and low CS molecular weight (MW) was investigated in this study. Diphtheria toxoid (DT) was used as a model antigen. The emulsion-solidification method was adopted for microencapsulation of DT. In the first step, following the purification of semi-crude DT by the ion-exchan...

An experimental inactivated oil-emulsion H9N2 avian influenza vaccine was formulated with 3 parts ofinactivated avian influenza antigen A/Chicken/Iran/101/1998(H9N2) emulsified in 7 parts of oil adjuvant.Twelve week-old specific pathogen-free (SPF) chickens were divided into seven groups of 10 birds. Sixgroups were vaccinated with 1, 1/10th, 1/50th, 1/100th, 1/200th and 1/400th field dose of th...
متن کاملInfluence of Casein and Inulin on the Properties of Fish Oil Nano-emulsion
The purpose of this study is to produce an oil-in-water nano-emulsion by ultrasonication. Casein combined with inulin used as continuous phase, while dispersed phase consisted of fish oil. The size of the nano-emulsion and the pH of nano-emulsion were characterized. Ultrasound has been used for preparing emulsion by 24 KHz intensity for 120 seconds. Prepared nano-emulsion was investigated by pa...
