Lipiodol Ultra-Fluide (0.2 ml/kg) was injected directly into the lymphatic vessels of the pelvic limbs in 28 healthy adult mongrel dogs. The contrast medium appeared on the roentgenogram in the popliteal, lateral iliac, medial iliac, sacral and lumbar aortic lymph nodes (LN). It was also visible in the iliofemoral, superficial inguinal and cranial mediastinal LN in several dogs. It diffused from the popliteal into the sacral, medial iliac and lateral iliac LN to fill the cisterna chyli and thoracic duct system. The features of the popliteal, lateral iliac and lumbar aortic LN were shown in the lymphangiograms of all the animals. The incidence of the other LN was different. Depending on the incidence of these LN in the lymphangiogram, the pictures of the canine lymphatic system were classified into three types:(1) medial iliac and sacral LN were visible on both sides (16%);(2) one of these LN was not observed (36%);(3) medial iliac and/or sacral lymph node was not observed on both sides (48%).
A diagnosis of tetralogy of Fallot was made in a male cat 8 months of age weighing 1.1kg. The antemortem diagnosis was based on physical and hematologic examinations, radiography, electrocardiography and phonocardiography. Necropsy revealed pulmonary stenosis (infundibular), high ventricular septal defect, dextroposition of the aorta and severe right ventricular hypertrophy. This might be the first feline case of Fallot's tetralogy ever reported in Japan.
To establish a clean area in the Tsubonuma district, Sendai City, where fascioliasis was enzootic, steps were enforced for 3 years beginning with 1978. They consisted of periodical administration with an anthelmintic, inhibition of use of fresh rice straw, and prohibition of use of fresh bovine feces as manure for paddy field. The Fasciola-positive rate, as determined by Taira's technique, was 48.5% before these steps were taken. It decreased to 20.4, 17.3, and 13.5% 2, 2.5, and 3 years after the application of these steps, when an EPG of 6 or more was noticed in 1, 0, and 1 animal, respectively. Taira's technique of quantitative determination of Fasciola eggs seemed to make it possible to clarify the actual enzootic condition of fascioliasis more clearly than before.
A flock of 1, 033 chickens was introduced into a broiler poultry farm, on which inclusion body hepatitis (IBH) occurred. Groups of 5 chickens were sacrificed at about weekly intervals over a period from (0 to 62 days of age), and a total of 51 chickens examined etiologically, serologically and pathologically. Intranuclear inclusion bodies in the liver were observed in 6 chickens 31, 41, and 56 days of age. The liver of a 31-day-old chicken showed fatty changes with multiple petechial hemorrhage and a large number of inclusion bodies in hepatic cells. Avian adenovirus was detected in the rectum from 21 to 62 days of age, in the liver from 31 to 62 days, and in the trachea from 56 to 62 days. The isolates were divided into 3 serotypes represented by the TR-59, SR-48, and Ote strains, respectively. The flock grew normally with a mortality close to that in usual performance, in spite of avian adenovirus invasion.
In the jurisdiction of the Tsuchiura Dairy Cooperative Society, Tsuchiura, Ibaraki, 6, 051 dairy cows were raised on 226 farms. In July, 1981, a survey was conducted on 100 farms selected at random, of which 18 were found to be contaminated by Fasciola infection, the highest EPG being 61. In the next month, a second survey was performed on 79 farms a in an area highly contaminated, two cows being examined on each farm. As a result, the positive infection rate was 19%. In September, 1981, a third survey was carried out on 71 cows raised on farms where the two selected cows had been proved positive for Fasciola infection. Of the 71, 10 presented an EPG of 10-36. The positive infection rate was 72%. In these manners, it was possible to detect heavily contaminated farms and areas.
A male dog suffering from urethral calculus was subjected to urethrostomy. Histopathological examination conducted 4 weeks after operation revealed a satisfactory adhesion between the penile tunica albuginea and the urethral mucous membrane and little contraction of the operative wound. This operation was proved to be applicable to the clinical practice.
