    The level of hemoagglutinin inhibiting antibody (HI antibody) to Japanese Encephalitis in the sera of the people in Pagoda Farm, Thailnd, in 1973 was studied.
    The results were as follows.
    1) The mode of frequency prevalence of HI antibody of the people showed 160 of titer, the rate of over 80 of titer being 92 per cent, that of over 160 of titer being 69 per cent and that of over 640 of titer was 22 per cent in the people of Pagoda Farm.
    2) The data of the people in Pagoda Farm were much higher than those of nonvaccinated people with Japanese Encephalitis in the southern district in Okayama prefecture, Japan, in 1967 where the mode of frequency prevalence of HI antibody titer of them was under 40 of titer, the rate of over 80 of titer being 17 per cent and that of over 640 of titer was 1 per cent.
    3) It can be said that there was a tendency of wide-spreaded inapparent infection of Japanese Encephalitis virus or virus having close-crossed antigenecity to Japanese Encephalitis virus in the people in Pagoda Farm.

    1. The date showing 50 percent positive HI reaction in swine was 21th of August in the southern district. The positive rate showed 95 percent at maximum in the southern district, suggesting that the decreasing amount of Culex Tritaniorhychus which transfer the JE virus from swine to human being is lessening.
    2. The rate of pupils and teachers having value under 10 in HI reaction was 72 percent before their receiving vaccination in a certain upper secondary school and that of outpatients was 81 percent in a hospital near pigpens in Kurashiki City.

    In order to forecast the incidence rate in the prevalence of Japanese encephalitis, in Okayama Prefecture, the authors took into consideration the following factors, average atmospheric temperature, duration of sunshines and rainfall amount in June and July as the climatic elements, date showing immunological positivity of haemoagglutination inhibiting reaction (HI reaction in short) on 50 per cent number of swine, positive rate on swine till the end of July, and the Logarithms of the numbers of Culex Tritaniorhychus till July 10th, the end of July, and August 10th.
    To make smallest the mean error yielded in the case of calculating with the multiple regression equation that consisted of factors, the most important and meritorius factors were selected from various factors above mentioned (14 factors in all) in 1966-1973 by the voluntary, forward selection methods devised by us. And multiple regression equations were made of the selected factors.
    When trying to forecast the incidence rate in the same prefecture, 2 factors, the Logarithms of total of C. T. involving male and female till July 10th, and the rainfall amount in June became useful. In the case of using 3 factors, the serological positivity of HI reaction on fifty per cent number of swine was added by forward selection method, and the average atmospheric temperature of June, that of July, and the rainfall amount of June became the factors by voluntary selection method. Using the multiple regression equation made from the 14 factors of 1966-1971, the incidence rate of 1973 was estimated. The results almost agree with the actual value.

    本年の8定点で採集を行い,昨年より総採集数の増加したのは笠岡保健所,倉敷東保健所,瀬戸保健所,津山保健所の4ケ所で,特に笠岡保健所ではC. p.の激増が見られた,倉敷保健所ではA. s.の増加が激しく, C. p.の雌も増加が目立っている。瀬戸保健所ではC. t., C. p.の雄が著しく増加している。津山保健所ではC. t., A. s.が増加し,特にC. t.の増加が著しかった。
    この外,岡山保健所のA. s.の雌が増えている。またC. p.の雌も増えているが,全体としては昨年の採集数より低くなっている。新見保健所ではC. t.の雌が増えている。これとは逆に倉敷市浜のC. p.の雌が減少し, C. t.では本年0を記録している。成羽保健所はC. p., A. s.共に昨年より減少し, C. t.では倉敷市浜同様0を記録している。
    本年はいわゆる北部においてC. t.の著しい増加が見られた点に特徴がある。
