Central neurocytoma is a rare, well-differentiated neuronal tumor and is usually located in the lateral or third ventricle of young adults. The occurrence of an intraventricular tumor with a characterisitic magnetic resonance image findings including isointense signal in T1-weighted images, the presence of a cystic component, small signal-void areas due to calcification, heterogenous and hyperintense "bubbly" appearance in T2-weighted images in a young patient should suggest preoperatively the diagnosis of central neurocytoma. The typical immunohistochemical finding, positivity for synaptophysin, is the main pathological feature. We experienced two cases of central neurocytomas with typical radiological and histopathological findings. We expect growth arrest of these cases by subtotal removal to avoid postoperative neurologic deficit followed by radiation therapy.

A Patient (Korean native cow, 4 years old, 300 kg, female), with chief complaint of anorexia for long period was admitted to the Chungnam national University Veterinary Medical Teaching Hospital. At necropsy findings, hard masses of necrotic fat were located in the omentum, rectum, kidney, colon, heart and thoracic cavity, respectively. The yellowish changes also were observed in liver, spleen and lung, respectively. In histopathological findings, fatty accumulation was observed by microscopic observation in each organ of fatty masses. Hamatological analysis revealed the low levels of Hb, PCV and neutrophil. Blood chemical analysis indicated the high concentration of Cholestelol and Triglyceride. That patient was diagnosed as typical case of lipomatosis by clinical, blood, blood chemical and pathological examinations.

The purpose of this study is to investigate the effect of acupuncture after the induction of acute kidney disease in dogs by ethylene glycol. Twenty four mixed breed, adult cats were used in the experiment. Ethylene glycol was administered orally at 1 ml/kg in 24 cats, and then 6 cats were treated by acupunchuture 6 cats were treated by electroacupuncture, 6 cats were treated by acupuncture and 6 cats were not treated as a control group. Treatment was done once daily far 4 dsys. The acupoint used were Gan-shu and Tai-xi. The effect of acnpuncture was evaluated by clinical symptom, blood chemical values, electrocardiogram (ECG) and histopathologkal findings. After treatement, acupuncture group revealed relatively fast recovery compared with other groups, in clinical symptoms, blood chemical values, ECG waves and histopathological findings. Laserpuncture group revealed secondly fast recovery compared with control group.

Although 'Cinnamon' has been widely used for the food and biophamacy in the world, it's toxicity was not screened completely. Major component of 'cinnamon' is CB-OH and CB-PH. CB-PH has been reported to have antimutagenic effect. To investigate the toxicity of 2-o-Benzoylcinnama-Idehyde (CB-PH), repeated dose (4 weeks) oral toxicity test performed in SD rats. Results of repeated dose oral toxicity tests for 4 weeks (CB-PH; 500, 1000, 2000 mg/kg/day) suggested that the CB-PH treated group showed no significant toxicological findings with body weights, organ weights, hematological and histopathological findings. Therefore, these data indicated that the maximum tolerated dose of CB-PH was 2000 mg above/kg/day in the rats.

The clinical and histopathological observation of leucocytozoonosis was carried out during July, 1982 at a poultry compound in Gyeongbuk province and the results were summarized as follows: 1. Leucocytozoonosis was observed in 36,900 of 59,900 chickens (61.6%) and the mortality rate was 18.3% (6,760 of 36,900 chickens infected). 2. Clinical findings were anorexia, dyspnea, paleness of comb, greenish diarrhea and reduction of egg production. 3. Gross lesions were yellowish white spots scattered on parenchymal organs and swelling of liver and spleen. In addition, petechiation and ecchymosis of small intestine, egg yolk and subcutaneous tissues were observed. 4. Histological findings were infiltration of mononuclear cells in liver, heart and lung, appearance of megaloschizonts in heart, liver, proventriculus and pancreas, proliferation of foreign body giant cells in heart, and hyperemia and swelling of all parenchymal organs.

The effect of relative humidity in swine house on swin pleuropneumonia was examined in piglets experimentally infected with Actinobacillus pleuropneumoniae serotype 5. A total of 20 piglet were grown under 30~40%, 41~50%, 51~64% and 65~80% relative humidity chambers after intratracheal inoculation of A pleuropneumoniae. Characteristic fibrinous pleuropneumonia was observed in the pigs grown at the low relative humidity groups. The detailed results were as follows : 1. Growth performance and environment conditions were lower than high relative humidity groups. 2. Characteristic histopathological findings were fibrinous pleuritis and pneumonia accompanied congestion, hemorrhage, thrombosis and edematous change. 3. Antigenic distribution of inoculated bacterium was found mainly in alveolar macrophages or accumulated foci of macrophages adjacent to necrotic area. 4. Characteristic electron microscopic findings were proliferation of type II pneumocyte with increased lamella bodies and activated alveolar macrophages with pseudopods and widening of interstitium.

A Shih Tzu Puppy had clinical onset of anotexia crying and progression of neurological sings when enlargement of the cranial vault at 1 month old and died after showing clinical signs during 2 months period. Radiological and pathological examinations were performed. Radiological findings were homogeneous appearance of the calvaria with cortical thinning, loss of the normal convolutional skull markings and persistent fontanelles. Grossly enlargement of the cranial vault thinning of the bone and defective closure of the fontanelles were also observed. The entire subcortical area of the cerebral hemispheres with severe, dilatation of ventricles and cerebrospinal fluid(CSF) wits absent. There was parenchyma atrophy affecting chiefly in the white mater and the cerebral cortices, axon degeneration and necrosis and gitter cell infiltration in the whiter matter and the subependymal area. Mononuclear perivacular cuffing in the cerebrum and the pons was shown. Based on the radiological, gross and histopathological findings, this case was believed to have congenital hydrocephalus with nonsuppurative encephahitis. Possible etiology on the case is also discussed.

Aspergilloma of the maxillary sinus is considered rare in immunocompetent patients, but a considerable increase has recently been seen in the incidence of reported cases. Dental procedures involving the antral region are thought to predispose individuals to this form of aspergillosis. Because aspergilloma shares similar clinical features with other sinus pathologies, its diagnosis may be delayed. Thus, an early diagnosis confirmed by a histopathological examination plays a crucial role in the adequate management of aspergilloma. This article provides a concise review of the reported cases of aspergilloma associated with dental procedures and reports 2 new cases of aspergilloma in middle-aged female patients, with a presentation of their cone-beam computed tomographic findings.
