RÉSUMÉ
A Clinical observation on 272 cases of epidemic encephalitis admitted to the Department of Pediatrics, Chonnam University Hospital with 5 year duration from 1971 to 1975 was carried out and the serum protein fractions were studied paperelectrophoretically on 28 cases in 1975 The following results are obtained. : 1) The peak age group was from 6 to 10 years old, and the male to female ratio was 1.7:1 2) The complaints on admission were fever(100%), neck stiffness(78.3%), Kernig's sign(71.7%), vomiting(64.0%), unconsciousness(59.6%), and headache(57.4%), in order of frequency. 3) Laboratory findings were as follows ; In the most cases(79.4%), peripheral leukocytosis with increased polymorphocyte was noted. And the findings of C.S.F. showed; Pleocytosis (98.5%), increased protein content(90.1%), normal or slightly increased sugar content(97.8%) and within normal limits of chloride level. 4) Mortality rate was 20.2% 5) The total protein and beta-globulin level showed no change and decreased albumin and A/G ratio. The gamma-globulin level showed increased initially and thereafter decreased to normlal limits gradually.
