PHARMACOLOGY: Biological Assay of Diphtheria Antitoxin
Presentation Description No rabiew available. Any suitable strain rabies virus of known potency, such as the CVS strain may be used. White mice weight 11gg. P Exposure the gluteus primus muscle thigh and remove politeal artery og crural vein.
You do not have the permission to view this presentation. Consciousness initially spared Two forms can overlap or progress from one to the other Coma after one week of neuro symptoms with death a few days after.
These two groups are used for titration of LD50 of challenge suspension. Hallucinations, seizures, ataxia, focal weakness and arrhythmias can occur. Protected from the light. The no of units per ml Either it is from horse of other mammals Recommended dose preservatives. Longitudinal Section of Rabies Virus: The no of units per ml Either it is from horse of other mammals Recommended dose preservatives Slide 9: Consisting free dried synthetic oxytocin peptide with human albumin citric acid.
For a human, rabies is almost invariably fatal if post-exposure prophylaxis is not administered prior to the onset of severe symptoms. 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.
Saline solution prepared having the 1ml contains 0.
The presentation is successfully added In Your Favorites. Dose should be added at regular interval[minutes] Slide The vaccine is prepared immediately before use by reconstitution from the dried vaccine with a suitable sterile liquid. Tetanus anti-toxin is a preparation containing antitoxic globulins vaccone have the power of specifically neutralizing the toxin formed by clostridium tetani.
Maintain its sterility by the addition of toluene or other antimicrobial preservative which does not cause a rapid decline in specific toxicity.
Sequential Steps of Rabies Transmission. Inject a dose of 0. Mice, 10gg -animal same sex. The potency of the preparation being examined is then determined in relation to the Standard Preparation using the test toxin. 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: Incubation at c for hrs.
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.

Never has been confirmed Rabies virus never isolated from blood Rabies virus: Zoonotic animals to humans. Nor inoculums is added incubate at hcs.
Standard cyancoblamine stock solution diluted with water[0. Dilute the test toxin with saline solution so that 1. The potency of rabies vaccine is determined by comparing a lethal intracerebral dose of a rabies virus with the dose of the standard preparation of rabies vaccines necessary to give for same protection.
Rabies virus Risk of developing rabies after a bite: Standard preparation is dried serum or Other preparationthe potency of which has bjoassay determined in relation to international standard. Potency is determined by international reference.
HCl [to PH 6. Allow the mixtures to stand at room temperature, protected from light, for 15 to 60 minutes.
On a graph paper, plot the transmittance value against the corresponding levels of std. Prepare standard solution with saline solution.
