Severity of exposure Location of the bite The biting animal Bites on head and neck have shorter incubation time as short as 15 days because of rich peripheral nerve supply Encephalitic Form: The no of units per ml Either it is from horse og other mammals Recommended dose preservatives Slide 9: Prepare fold dilution of std.

Suspend the cells in 10ml of sterile suspension medium 1ml of the suspension of cells 10ml sterile suspension mix the inoculums Slide Maintain its sterility by the addition of toluene or other antimicrobial preservative which does not cause a rapid decline in specific toxicity. Similarly record the contraction of test preparation as standard.

LP means limes paralyticum This is the smallest quantity of the toxin when mixed with 0. By contraction of the rat uterus: On the other hand another vaccine, derived from the LEP strain, was considerably more potent in antigenicity assays than in immunogenicity assays.



For this purpose, a suitable preparation of diphtheria toxin is required to be used as a test toxin. Neomycin sulphate is a mixture of compounds obtained by the growth certain strains of streptomyces fradie. Observe the animals for 48 hours. Potency is determined by international reference.

PHARMACOLOGY: Biological Assay of Diphtheria Antitoxin

Standard cyancoblamine stock solution bioassayy with water[0. HCl [to PH 6. It is a neurosecretary product mainly synthesize in the cell bodies of paraventracular nuclear of the hypothalamus.

The potency of diphtheria anti-toxin is determined by comparing the dose necessary to protect guinea-pig or rabbits against the erythrogenic effect of a fixed dose of the bioassy preparation of diphtheria anti toxin necessary to give the same protection. P otency of rabies vaccine is determined by comparing a lethal intra-cerebral dose of a rabies virus with the dose of the standard preparation of rabies vaccines necessary to give for same protection.

Dilute 25ml of basal medium stock solution with equal volume of H2O sterile in autoclave. Three rabies vaccines for human use derived from different rabies virus strains and prepared on different cell culture substrates were compared with the International Standard for Rabies Vaccine using in vivo and in vitro caccine methods in a collaborative study involving 14 participants.

P response Cannulate the crural or brachial vein. Viral disease – cause acute encephalitis inflammation of the brain in warm-blooded animals. Cannulate the popliteal artery is record the B. For a human, rabies is almost invariably fatal if post-exposure prophylaxis is not administered prior to the onset of severe symptoms. The presentation vaccinne successfully added In Your Favorites.

Oxytocin bioaesay the contraction of uterus. It is obtained by fractionation from the serum of horses or other mammals that have been immunized against diphtheria toxin. The potency of rabies antiserum is determined by comparing a lethal intracerebral dose of rabies virus with the dose of standard preparation of rabies antiserum necessary to give same protection.
