A male mongrel puppy 11 weeks old had heavy ascites. The liver and right kidney were enlarged and palpable. Death occurred about 4 months of age. Necropsy was carried out within 48 hours after death. Gross findings were blood-stained acites, hydrothorax, a large tumor about 15 cm in diameter and reddish-white in color located at the site of the right kidney, and numerous reddish-white nodules varying in size in many organs. The pancreas, liver, mesenteric lymph nodes, diaphragm, lung, bronchial lymph nodes, mediastinum, and pleura were also involved. Microscopically, the large tumor mass and metastatic nodules showed the same structure, that was composed of polyhedral-cells with a round nucleus and fairly basophilic cytoplasm with reticular fibrous fringe. This tumor was regarded as reticulum cell saroma with widespread metastasis.
The authors tried to apply a “secondary hepatectomy method” to the hepatopathy (tumor, hepatophyma, injury, etc.) in dogs. For this purpose, it is important to know the accurate bifurcation-form of the vena portae and the extent of the lobe that is under the control of the vein. In addition, it is necessary to determine the ratio of the weight of each lobe to that of the whole liver of the dog. The former was examined in 5 healthy dogs, and the latter in 30 healthy dogs. The results are tabulated as follows. Extrahepatic vena Its controllable Lob. Weight/portaelobe Total hepatic weight Lob. sinister lat. Lob. sinister med. Truncus sinister Lob. quadratus 73.3% Lob. dexter med. Proc. papillaris Lob. sinister lat. Pars umbilicalis Lob. sinister med. 48.0% Lob. quadratus Truncus dexter Lob. dexter lat. 26.7% Proc. caudatus Ramus ascendens Lob. dexter med. 19.5% dexter Ramus ascendens Lob. quadratus 6.2% sinister Rami processi Proc. papillali 5.8% papillaris
A simple method was devised for making blood films. It was performed in the following manner. The end without chemical of a commercial matchstick was dipped, about 5mm in depth in blood contained in a tube with the anticoagulant EDTA. Then, by the aid of the stick, 5 lines of blood smear were made on a slide in parallel with the long side of the slide. At the time of smearpreparation, it was not necessary to take the moving speed of the stick, and the angle between the slide and the stick into consideration. Blood films prepared by this method had always portions of any line on the slide suitable for microscopic observation on red and white blood cells and thrombocytes. Besides, there was no significant difference between the conventional silde method and this method in the rate of appearance of any of the 5 kinds of leukocytes.
