A subacute toxicity study of a potent tetanus toxoid (250 Lf) was carried out in guinea pigs.The toxoid was injected subcutaneously at the nape of the neck at dose levels of 1.0, 1.5.and 2.0 ml in Groups Ⅱ.

Ⅲ. and Ⅳ, respectively.In the controls (Group Ⅰ) 2.0 ml of aluminum phosphate suspension was given in each injection.Periodic evaluations of body weight, food/water intake, general observable behavior, hematology.and blood chemistry in toxoid-injected guinea pigs were similar to those in control guinea pigs.Thus, the toxoid did not cause any side effects up to four times the dose proposed for humans.1990 Academic Press, Inc.展开更多

The safety evaluation of the vaccine has been reported, but the teratogenic potential was not studied. In the experiment reported herein we have studied the teratogenic action of the vaccine in the progeny of rabbits. No congenital anomalies were observed.展开更多

Heat inactivated HIS possessed a comparable agglutinating activity as the non-inactivated controls. Non-inactivated normal (unimmunized) serum caused immobilization of Giardia trophozoite, which was checked on heat inactivation. Antibodies in immune sera are mainly responsible for agglutination, whereas the heat labile non-immune components control the mobility of the intestinal parasite.展开更多
