Pathological investigation was carried out on 10 cases of lymphosarcoma in swine. Cytologically, neoplastic cells in these cases presented essentially the same morphological characteristics as lymphocytes. Neoplastic lesions were recognizable predominantly in lymph nodes, liver, spleen, kidney and urinary bladder, and additionally in many other organs macroscopically or histologically. They were remarkable in tonsil, genital organs, bone marrow, nervous tissue, pancreas, adrenal, hypophysis, tongue, submaxillary gland and gallbladder. Their histogenesis was suggested to consist in the accumulation of neoplastic cells throughout perivascular areas, judging from the character of these cells.

Salmonella typhimurium, Copenhagen variety was isolated from 13 domestic pigeons (Columba livia domestica) of 4 pigeonries in which clinical salmonellosis occurred during the period of 1970 to 1975. Of 58 composite fecal samples collected from feral pigeons (Columba livia domestica) in 13 districts of Honshu and Hokkaido in 1975 and 1976, 12 (20.7%) from 3 districts gave the same antigenic form. The antigenic form was also isolated from the tissues of 2 (1.8%) feral pigeons (Columba livia domestica) caught at one site among a total of 110 feral pigeons (80 Columba livia domestica and 30 Streptopelia orientalis orientalis) caught in 3 districts of Hokkaido in 1976. No Salmonella other than S. typhimurium, Copenhagen variety was obtained from pigeons. These isolates fermented maltose, and belonged to biovar 10 [2]. All the isolates from feral pigeons and most of those from domestic pigeons showed in-vitro drug sensitivity. S. typhimurium, Copenhagen variety having the same characteristics was isolated from animals, chickens and wild birds, though the antigenic form originating from hosts other than pigeons was drug resistant with variable frequencies, and different biovars were found in some hosts. This appears to indicate that pigeons have a role in the epizootiology of salmonellosis in animals and birds in Japan.

Canine oral papilloma cells were cultivated in vitro by the trypsinization procedure. The success of primary cell culture depended on the choice of a proper stage of papilloma growth. Dome-shaped papilloma was suitable for cultivation. Cultivated cells were flat, and round or polygonal in shape. They were piled up or overlapped, and keratinized cytologically. From the normal mucosa, fibroblasts and epithelial cells were cultivated only by explant culture, while the epithelial cells were neither keratinized nor piled up.

In both bled and non-bled dogs under ketamine hydrochloride anesthesia, sinus tachycardia was sustained, but no particular irregularities were found in the cardiac rhythm. After ketamine anesthesia somewhat apparent changes occurred to ECG waves and ST deviation and the P-Q and Q-T interval (lead II) were relatively prolonged in the bled dogs, as compared with the non-bled dogs. The changes in EEG waves during ketamine anesthesia were of essentially the same pattern in the bled dogs as in the non-bled dogs, although the amplitude was lower in the former than in the latter.

A total of 1, 186 dogs from Gifu and Shiga area were surveyed for Brucella canis (B. canis) during a year from April, 1976 to March, 1977. The dogs with serum agglutinin titer of 1:320 or higher against B. canis were sacrificed and their various organs and fluids were cultured for the organisms. Through the year, detection rate confirmed by isolation of B. canis was 2.8% (33 dogs) and no statistically significant difference was found between the two groups (2.5% in Gifu and 3.5% in Shiga), nor between males and females (16 and 17, respectively). Monthly detection rates of infected dogs were fluctuated from 0.8 to 5.5%, but no clear seasonal influence was found. Among the surveyed dogs there were 188 pure bred dogs including 123 dogs weighing more than 20 kg, but non of them was positive for B. canis. All positive dogs were mongrel. B. canis was isolated from various organs, most frequently from the prostate and bladder urine for males and from the lumen of uterus for females in addition to the spleen and lymph nodes of both sexes. B. canis was isolated from bladder urine in 14 out of 16 males, but only 5 out of 17 females by direct cultural method. The number of viable B. canis in bladder urine was more abundant in males than in females. The importance of urine as one route of dissemination of the organism was discussed.

家畜の眼球について形態学的研究を行った. 採取眼球のうち馬16個, 牛28個, 山羊26個, 豚30個, 犬18個, 猫20個および兎28個の眼球については各部位を計測し,ー方, 残りの馬8個, 牛22個, 山羊14個, 豚18個, 犬20個, 猫26個および兎16個の眼球の各部について走査型電子顕微鏡による観察を行った. 各部位の計測値は動物の種類により特異的なものであった(Table 1). 走査型電子顕微鏡観察の結果では, それぞれの動物の種類において各部位に特徴的な所見が得られた. 虹彩顆粒は馬, 牛, 山羊のほかに, 豚や犬でも小顆粒が瞳孔縁全周に配列することが認められた. 毛様体突起は動物種によりその形態を異にし, 馬や牛では太く, 起始部は分岐しないが, 山羊や豚では高いものと低いものがあり, 犬や猫では低い突起が集まって櫛状を呈する. 毛様小体は種々な太さの線維束から構成され, その伸長径路も動物種間で差が見られ, 硝子体包に終止する部位は特異なV字型(牛, 山羊, 犬, 兎), 楔形(馬, 豚), 馬蹄型(猫)を呈した. 水晶体には動物間による構造上の差はみられなかったが, 水晶体線維面に多数の小孔の存在が確認された. 視神経円板は各家畜により形態を異にするが, 牛および山羊ではこの部位に硝子体突起の存在が認められ, その立体構造が明らかにされた.
