Dephtheria anti-toxin is preparation containing antitoxic globulins that they have the power of specifically neutralizing the toxin formed by Cornebacterium diphtheria. Hallucinations, seizures, ataxia, focal weakness and arrhythmias can occur. Prepare mixture of solution: On a graph paper, plot the transmittance value against the corresponding levels of std.

Upload from Desktop Single File Upload. The test dose of the toxin is determined in relation to the Standard Preparation. LP means limes paralyticum This is the smallest quantity of the toxin when mixed with 0. Automatically changes to Flash or non-Flash embed. Saline solution prepared having the 1ml contains 0. Dose should be added at regular interval[minutes]. The presentation is successfully added In Your Favorites.

PHARMACOLOGY: Biological Assay of Diphtheria Antitoxin

The Standard Preparation is the Ist International Standard for Diphtheria antitoxin, equine, established inconsisting of the dried hyperimmune horse serum and glycerin, or another suitable preparation the potency of which has been determined in relation to the International Standard. Neomycin sulphate is a mixture of compounds obtained by the growth certain strains of streptomyces fradie.


Go to Application Have a question? Three rabies vaccines for human use derived from different rabies virus strains and prepared on different cell culture bioxssay were compared with the International Standard for Rabies Vaccine using in vivo and in vitro assay methods in a collaborative study involving 14 participants. Great information, I would like to say your post is very informative.


In selecting a toxin for use as the test toxin determine the following: Consisting free dried synthetic oxytocin peptide with human albumin citric acid. Dilute 25ml of basal medium stock solution with equal volume of H2O sterile in autoclave.

By contraction of the rat uterus: Nor inoculums is added incubate at hcs. Internal between two injection between minutes depending on the rate at which B.

The results of this study indicate that the NIH protection test should continue to form the primary basis for potency assay of rabies vaccine as glycoprotein content does not appear to correlate with immunogenic potency for different types of vaccine.

Automatically changes to Flash or non-Flash embed. Suspend the cells in 10ml of sterile suspension medium 1ml of the suspension of cells 10ml sterile suspension mix the inoculums Slide Transmission Almost all transmission is by bite 50 times greater risk than a scratch One human case may have been acquired in a laboratory transmitted by aerosol In wild animals: Standard preparation containing freeze dried hyper immune horse serum.


Rabies Vaccine Assay Test Animals: Observe the animals after 48hrs Mixture containing larger amount of toxin gives the larger reaction Mixture containing less amount of toxin gives the smaller reaction Slide 6: Centrifuge decant of supernatant liquid [repeat 3 times].

The test toxin is allowed to stand for some months before being used for the assay of samples of antitoxin. Never has been confirmed Rabies virus never isolated from blood. These two groups are used for titration of LD50 of challenge suspension.

Prepare mixtures such that 2. You do not have the permission to view this presentation. P Exposure the gluteus primus muscle thigh and remove politeal artery and crural vein. Prepare standard solution with saline solution.

Allow the mixtures to stand at room temperature, protected from light, for 15 to 60 minutes. Record the contraction produces by the addition of two dose of std. The presentation is successfully added In Your Favorites.
