October, R. 1963 Assam Trip Bangkok Feb. 1 have been bitten by harmless snakes. It is usually easy to distinguish between common poisoning from neurotoxic and hemotoxic venoms. It is difficult, however, to distinguish krait from cobra, if the victim did not see the snake. Treatment is for cobra, since krait bites are so rare. The krait is disinclined to bite and unless hurt in some way will usually not bite. King cobra bites are rare because it is a jungle snake. The Institute treats rabies cases. There is considerable dog rabies in Thailand. It also maintains a blood bank. I forgot to mention that in testing serum to see if it is up to titer, a given quantity of serum is mixed with a particular amount of venom that it should be capable of neutralizing. The mixture is then injected into mice. If they survive, the serum is considered O.K. These specific antivenoms have a dramatic effect. A person may come in comatose from cobra bite and in a few minutes is recovering, following injection of serum. If a person is sensitive to horse serum, the injection is made intramuscularly, or intradermally or even into the blood via an infusion.
