responses, including a significant decrease in albumin and a marked rise in gamma- andJoeta-globulins. The alpha globulins were reduced and the A/G ratio decreased moremarkeclly in these cases than in uninfected aninnals. The cconcentration of total proteinshowecl a tendency to decrease about 100 days after infection, although hyper-ga, rruma-globulinemia and hypoalbuminernia remain throughout the experimental period.In naturally ittfccted cattle, total protein and a[joha, globtv, lit showed no significan?tdifference in quantity, as compared with uninfected cattle. XV marked rise in gamma andbeta glooulins and a marked decrease in albumitt were ooservecl in the former.

カルシウムの生体内作用は,イオン化Caの作用によると考えられている.そこで著者らは,家畜内科学の面から,Caに関係があると考えられる疾病の血清透析性イオン化Caを検討し,これが変動するとき,とくに低血清透析性Ca状態が生体の防衛反応に対する意義を究明L7ようとした2第I報においては,健康犬血清Caの年齢的勤揺?範囲とともに,血清総蛋白量および血液の一般性状を測定した.ついで,これによって得た総Caに対する透析性Caの比率(イオン化率)を求め,血清透析性Ca(SICと略す)について,柳沢法による実測値とMCLEANの理論値(それぞれ単に実測値,.理論値と呼ぶ)とを比較検討した.健康成犬23例について,血清Caを測定した.その結果,平均値をとると,SICは4.2±0.24mg/dl(以下単位をはふく),血清総Caは11.0±0.29,蛋白結合型Caは6.8±0.39となり,理論値から求めた血清イオン化Caの平均は4、8±0.23であった.馬5例の平均では,SICが5.2±0.91,理論値が5.6±0.25,血清総Caが12.5±0.28であった.牛10例の平均では,SICが4.4±0.35,理論値が5.5±0.18,血清総Caが12.2±0.18であった.豚5例の平均では,SICが5.1±0.99,理論値が5.4±0.88,血清総Caが12.1±1.54であった.羊10例の平均では,SICが4.4±0.29,理論′1:Kが5.3±0.21,血清総Caが11.0±0.24であった.健康と見なされた大87例を,年齢的変動を観察する目的で,生後24時間・1週令・3週令・5週令・15週令・1才および2才以上の8群に分け,血清Caを測定した.その結果,1週令群および15週令群において,SICが低下する傾向を認めた.これらの測定成績をみると,健康成犬を始め,馬・牛・豚・羊において,いずれも理論値が実測値よりも高い.このことは,実験上の手技の誤差範i.川だけでは,説明できないものがある.MCLEANの計算は,Caイオンと蛋白質の結合が血漿内において可逆平衡の状態にあるという仮説のもとに作成された式および図表を用いている.そこで,動物は全ぐ鮭康かつ正常であることを前堤としているはずである.したがって,この前提がくずれた場合には,理論値が実測値と異なることがあり得ると考えられる.以上の理由から,ここに得られた実測値と理論値どの差は,いたし方ないものと思われる.今後は,各種の内科疾患における血清Caの動態を検索するとともに,その異常状態が生体に及ぼす影響を追究していきたい.

私どもは1959年11月から12月の1カ月間にわたり広島県下のと畜場に搬入された牛の腸間膜淋巴節およびふん便各々467例,豚の腸間膜淋巴節およびふん便各々216例について赤痢菌の検索を実施し,次の如き成績が得られた.1.牛の腸間膜淋巴節467例中1例(0.2%)からShigellafexneri2bを検出した.2.豚のふん便216例中2例(0.9%)からShiーgella2aを検出した.3.牛のふん便および豚の腸間膜淋巴節からは赤痢菌は検出されなかった.牛及び豚から赤痢菌が検出されたのはわが国では本例が最初の例と見做される.なおこのような保菌例の存在は,これらの動物が赤痢の媒介者となり得ることを示唆するものであって,公衆衛生上軽視出来ない事実と考えられる,
