21犬種, 160例の犬を一般臨床所見によって1群 (良好), II群 (軽症), III群 (中等症あるいは不良), IV群 (重症) の各群に分け, 各群について, Hb, AIG比, TP, Htを測定し, その平均測定値を4本の等間隔に引いた平行線上にプロットして血液スペクトルグラフを作り比較検討した.
I群は正常値範囲内を上方から下方に連らなる折線グラフとなる.
II群はAIG比が正常値範囲より左に転位した折線グラフとなる.
III群はHb, AIG比が正常値範囲より左に転位した折線グラフとなる.
IV群はHb, AIG, TPが正常値範囲より左に転位し, Htは右に転位した折線グラフとなる.
以上に示した所見から血液スペクトルグラフは病勢の推移を知るのに有効な方法と思われる.

Thirty-five dogs were used to select a site of measurement of venous pressure practical for the private practice. As a standard point of measurement, a site was selected in a position one-third from the lower end of the space between the manubrium sterni and the trachea in a dog lying on the back. Then comparison was made among central venous pressure (VP), right jugular VP, and left femoral VP with some results.

Diagnostic records on 208 indigenous Japanese Black cattle revealed that fat necrosis had been found in the adipose tissue around the colon in 82.7% of the cattle, that around the rectum in 42.3%, and that around the kidney in 27.9%. Actual examination of 33 cattle encountered at the abattoir revealed that fat necrosis had been found in the adipose tissue around the colon in 88.0%, that around the rectum in 27.3%, and that around the kidney in 30.3%
Grossly, necrotic masses of fat varied in size from the tip of the little finger to the head of the human adult. They were surrounded by a thick layer of connective tissue, causing stenosis or occlusion of the organ. Histologically, necrotic fat cells were enlarged a little, containing needle-like crystalline bodies arranged radially in the cytoplasm. They were surrounded by foam cells and syncytia of these cells, as well as giant cells against foreignbody.

Chlorobromofebrifugine (CBF) was evaluated for anticoccidial activity in chicks and cultured cells infected with various species of coccidia. The results obtained are summarized as follows.
(1) Battery tests were carried out in chicks experimentally infected with oocysts of laboratory strains of Eimeria tenella, E. acervulina, E. maxima or E. brunetti. Dietary administration of 3 or 6 ppm CBF was found effective, but 1.5 ppm was considerably ineffective. Two field isolates, F-1 resistant to amprolium and clopidol and F-2 to these drugs and robenidine, were used in battery tests with CBF and gave results similar to those given by the laboratory strains mentioned above.
(2) The appearance of immature and mature schizonts was conspicuously inhibited when 0.01 or 0.001 ppm CBF had been added to the culture medium of E. tenella in BHK 21 cell culture.
