부산 시내 어시장에서 구입된 까치복어, Fugu xanthopterus의 조직부위별 독성과 특정부위의 독성간 상호관계를 mouse bioassay법에 의하여 비교 검토하였다. 즉, 개체당 전체 독량이 0∼36,816 MU로써 개체에 따라 독성차이가 있으며, 간, 난소 그리고 내장의 평균독성은 각각 110.0±25.0, 115.0±33.0 및 73.0±20.3 MU/g(평균치±표준편차)이었다. 또한 각 부위별 독성의 빈도순서는 간(88%), 난소(80%), 내장(75%), 정소(71%), 담즙(71%), 껍질(54%), 그리고 근육조직(13%)의 순이었다 한편 간과 내장, 껍질, 난소조직의 독성은 그 상관계수가 각각 r=0.93, r=0.79 및 r=0.83으로 뚜렷한 상관관계를 나타내었다.

Twenty-four specimens of the pufferfish Fugu xanthopterus, Korean name, $quot;Ggachibog$quot;, collected at a fish market of Pusan were examined for anatomical distribution of toxicity by the mouse bioassay method. Frequency of toxic specimens was 88, 75, 54, 13, 71, 80 and 71% , in terms of liver, intestine, skin, muscle, testis, ovary and bile, respectively. Their the highest toxicity scores were 417, 387, 112, 17, 39, 403 and 178 MU/g, respectively; and average toxicity values were 110±25.0(mean±S.E.), 73±20.3, 17.8±5.1, 2.7±1.1, 15.6±5.4, 115±33.0 and 34±9.3 MU/g, respectively. A significant correlation between the toxicities of liver and intestine(r=0.93), between those of liver and skin (r=0.79) and between those of liver and ovary(r=0.83) was observed.
