The histopathologic findings of the intracranial meningioma are variegated and those of magnetic resonance imaging (MRI) which has been used for preoperative evaluation are also vaned in signal characteristics. In order to aid the preoperative diagnosis, authors analyzed MRI and microscopic findings in twenty eight meningioma cases which underwent surgery. The results were summarized as follows: 1) Meningothelial, fibrous and transitional subtypes showed isointense signal on T1-weighted image and iso and/or hyperintense signal on T2-weighted and proton density images compared to the signal intensity of the gray matter. 2) Microcystic subtype was isointense signal on T1-weighted image and hyperintense Signal on T2-weighted and proton density images. 3) Variation of signal intensity might be correlated to the ratio of the stroma in the tumor. 4) Peritumoral edema was not closely related to the pathologic subtypes or location of meningioma, but it seemed to be correlated with the sue of tumor.

Hepatocellular carcinoma is one of the most common malignancies reported in ost of the Africa and South-east Asia. As hepatocellular carcinoma metastases well to distant site, half of the cases metastases to distant site at diagnosis. Hepatocellular carcinoma usually spread to regional lymph nodes around porta hepatis via lyphatics and venous metastasis can occur via intrahepatic vein. The usual sites of extrahepatic metastasis are lung, local lymph nodes, adrenal glands and bones, but epidural metastasis is very rare. Although the prognosis of the hepatocellular carcinoma was very poor in the past, the survival time seemed to be prolonged by early diagnosis and improvement of medical therapy. Therefore the importance of metastatic lesion of the hepatocellular carcinoma might be reemphasized. Recently we experienced a case of the hepatocellular carcinoma who developed paraplegia suddenly. MRI revealed ovoid epidural rnass at 6th and 7th dorsal vertebra level posteriorly. After emergency operation, the resected mass was confirmed metaststic hepatocellular carcinoma.

This study was performed to investigate the antimicrobial effect of the Viscum album var. coloratum extracts against food-borne pathogens. First, the Viscum album var. coloratum was extracted with methanol at room temperature and the fractionation of the methanol extracts was carried out by using petroleum ether, chloroform, and ethyl acetate, and methanol, respectively. The antimicrobial activity of the Viscum album var. coloratum extracts was determined by using a paper disc method against food-borne pathogens and food spoilage bacteria. The petroleum ether extracts of Viscum album var. coloratum showed the highest antimicrobial activity against Bacillus cereus and Shigella dysenteriae. Synergistic effect in inhibition was observed when Viscum album var. coloratum extract was mixed with Perillae folium extract as compared with each extract alone. Finally, the growth inhibition curves were determined by using petroleum ether extracts of Viscum album var. coloratum against Bacillus cereus and Shigella dysenteriae. The petroleum ether extract of Viscum album var. coloratum had strong antimicrobial activity against Bacillus cereus at the concentration of 5,000 ppm. At this concentration, the growth of Bacillus cereus was retarded more than 24 hours and up to 12 hours for Shigella dysenteriae. In conclusion, the petroleum ether extracts of Viscum album var. coloratum inhibit efficiently Bacillus cereus and Shigella dysenteriae.

Gingival fibromatosis which represents a fibrous hyperplasia of the gingival tissue is relatively uncommon benign oral condition. Characteristically, the firm enlarged gingival tissue often obscure the anatomic crowns of the teeth. They may deform palatal contours and subsequently crowd the tongue with a resultant interferance in speech and mastication as well as inability to maintain normal lip closure. Numerous examples not accompanied by ingestion of dilantin sodium, hypertrichosis, hereditary factors, cherubism, or ectodermal dysplasia have been generally labeled idiopathic . Although it has been stated that the treatment of choice is surgical removal of the enlarged tissues, there is a tendency for the condition to recur within a few years. The patient, 21-year-old female, was admitted to department of dentistry, Dong San Hospital, Keimyung University with the chief complaint of mastication difficulty and cosmetic problem-elephantiasis gingivae. She showed severe fibrous enlargement of maxillary and mandibular attached and nonattached gingivae. The gingival tissues generally were firm and dense, and the teeth were covered with dense, fibrous tissues, and this tissues may interfere with eruption. There was an operation history of excision of excessive gingival enlargement at five year old. She was diagnosed empty sella syndrom with partial hypopituitarism at endocrine tests. We got the good results in esthetics and functions by extraction of all teeth and surgical excision of the hyperplastic gingival tissue followed by complete dentures.
