ジャーナル フリー最近数年間に牛6例, 豚1例の子宮または膣における腫瘍を検索し次の成績を得た. 子宮腫瘍では5例中4例 (牛3, 豚1) が平滑筋腫, 1例 (牛) が平滑筋肉腫であって, 繁殖障害の有力な因子の一つになっていることがうかがえた. また膣腫瘍は2例 (牛) に認められ, 平滑筋腫と線維腫がそれぞれ1例つつでいずれも摘出手術により治癒した. 従来, わが国では生殖器腫瘍の報告は比較的少ないが, 今後, 診断・治療に際し留意する必要があるものと考える.抄録全体を表示PDF形式でダウンロード (9822K) -

ジャーナル フリーIt is possible to prevent stillbirth in swine caused by infection with Japanese encephalitis virus by inoculating sows with 2 or 3 10-ml doses or 3 5-ml doses of the existing high-potency Japanese encephalitis vaccine. This trial was carried out in Shizuoka Prefecture in 1969 to find a possibility of reducing the amount and the number of doses of vaccine for inoculation. In it, a vaccine was prepared tentatively in such manner as to contain tissues at a concentration about 3 times as high as that of the existing high-potency vaccine.
A total of 119 nulliparous swine were divided into 5 groups, A to E. Group A of 27 antibody-negative animals was inoculated with two 10-ml doses of the existing high-potency vaccine, and group B of 29 animals with a single 10-ml dose of the tentatively prepared high-concentration vaccine. Group C of 24 animals was set up as uninoculated control group, and group D of 28 antibody-positive animals as another control group. Group E of 11 antibodypositive animals was inoculated with a single 10-ml dose of the high-potency vaccine. In caeh group, antibody titers were determined 3 weeks after inoculation and immediately after parturition, and the results of delivery recorded.
After inoculation 100 and 96 % of the animals of groups A and B, respectively, turned to be positive for antibodies, neutralizing and hemagglutinationinhibiting.
The average number of young normally delivered per litter was 8.3 (in 16 sows examined) in group A, 8.2 (in 17 sows) in group B, 5.3 (in 14 sows) in group C, 9.7 (in 15 sows) in group D, and 9.7 (in 7 sows) in group E. There was a marked difference in this number between the inoculated groups (A and B) and the uninoculated control groups, but no difference between groups A and B.
Group B presented no inferior results of delivery but relatively low rate of antibody production and average antibody titer, as compared with group A.抄録全体を表示PDF形式でダウンロード (997K) -

ジャーナル フリーLymnaea truncatula is one of the oldest snails ever known as intermediate host of Fasciola hepatica in Europe. It has been clarified tha tthe intermediate host present in Japan is L. ollula. Recently, L. truncatula and Physa acuta have been found in the northern and the southwestern part of Japan, respectively. Higashi verified experimentally that the latter might have a role as an intermediate host.
The present authors tried to induce experimental infection with miracidia of liver flukes (Fasciola sp.) in two species of snails, L. truncatula and Physa sp., which had been collected from a stream in Taki County, Hyogo Prefecture, Japan.
L. truncatula was examined for possibility of acting as snail vector for liver flukes. No development of larvae was seen, except an aberrant development which was observed when the snail was exposed to miracidia of liver flukes within 6 or 7 days after the infection. It is clear that the Japanese L. truncatula is identical with no species of snails in Europe from a biological point of view, thouth it is very close to the snail in Europe morphologically.
Experimental infection was carried out twice with a very large number of miracidia of Physa sp. As a result, no development of miracidia or sporocysts was seen in the snail at either time.
The above-mentioned results indicate that no larvae of liver flukes invading L. truncatula and Physa sp. could develop in to rediae or cercariae in the field.抄録全体を表示PDF形式でダウンロード (5174K) -
