ON A CASE OF EPILEPSY IN A LION

"A male lion, estimated to be 10 years old, was transferred to Sapporo Zoo in October 1952 and was kept there until June 28th, 1953, when the animal died at 10 a. m. During the time kept in the zoo, the animal manifested four fits of epileptic type such as convulsion, inversion, unconsciousness etc., and the symptoms always recovered in a short time. The animal died in the last fit."

"Autopsy number P. 3409, post mortem about 24 hours. A carcass of lion, male, not emaciated, weighed approximately 170 kg. Rigor mortis was observable on all extremities, smooth and wet conjunctivae, relaxed and slightly clouded cornea. Buccal mucous membrane in normal, reddish fluid leaked through nostrils, subcutaneous tissues slightly exsiccated, no lesions on fat and muscles. Peritoneal fluid was slightly increased and reddish, peritoneum had no sign of abnormality. Blood vessels of large omentum dilated and congested. Spleen weighed 750 g, margin dull, cut surfaces convexed and glazed, blood content of parenchyma increased and with distinctive trabeculae and follicles. Liver, 3600 g, was subcapsularly congested, fibrinous membranes qn the diaphragmatic surface, blood content increased on cut surfaces, and congested parenchyma. Mucous membrane of cholecyst was congested. Pancreas weighed 120 g. Mesenterium was congested and some of mesenteric lymph nodes showed cyst-formation. Congested medulla of suprarenal glands and thin cortex. Kidneys weighed 450 g respectively, thick and fibrous capsules, subcapsular blood vessels ramiformly congested, elastic consistensy, and glomerular hyperemia on cut surfaces. Renal pelvis in normal. Pigeon-egg size testicles and slightly increased interstitial connective tissue. Poor content in stomach, serosa congested and mucosa was anemic with sporadic grayish white miliary nodules. As to the changes of small intestine; poor content, brownish feces in ileum, in serous and mucous membranes no pathological changes. Large intestine in normal. Thoracic fluid was slightly increased and reddish. Pleura was normal. Oesophagus showed ramiform hyperemia of mucosa. Content of pericardIum was reddish, watery and slight. Heart showed subepicardiac congestion, large amount of tar-like blood clots in the right ventricle and auricle, discovered about 10 Dirofilaria-worms from the right ventricle to pulmonary artery, no sign of pathological symptoms in endocardium and valves, myocardium congested and its elasticity decreased. Lungs were rich in air content, pleura in normal, slight anthracosis of parenchyma, small amount of reddish viscid mucus in bronchial. lumina, and pulmonary arteries contained liquid blood. Pulmonary hilus lymph nodes were thumbhead-size and slightly anthracotic. Tongue showed hyperemia on the mucosa of its root. Tonsils in normal. Laryngo-pharyngeal mucous membranes congested. The brain, weighed 200 g, had marked macroscopical changes. The lateral ventricles dilated with increased transparent cerebrospinal fluid. Multiple small focal lesions could be observed by making many frontal cut surfaces at about 5 mm intervals after formalin fixation. The foci were yellowish-brown or reddish-brown in colour, more indurative than the peripheral normal tissue and their size ranged from that of poppy seed to rice grain, and sometimes showed the appearance of ring hemorrhage. The foci were almost always clearly demarcated, mainly distributed in subcortical white matter or inner layer of cortex of cerebral hemispheres, and were found diffusely in the area from frontal to occipital lobe and also in hypothalamus, but no lesions confirmed in midbrain, pons, medulla oblongata and cerebellum. Total number of the foci was more than twenty. The foci were more densely found in the dorsal part than the ventral."
