To observe whether the measurement of enzyme activity has any critical role in assesment of diagnostic value, beta-glucuronidase and lactic dehydrogenase activities in neoplastic tissue of stomach were compared with those in the stomach at the stomach mucosa at the antrum and body which was uninvolved by tumor. And then activities of those enzymes were also compared with differentiated and undifferentiated carcinomas. The stomach tested were obtained by gastrectomy in Pusan National University Hospital during the months from March to June in 1983. The results were summarized as follows: 1) beta-glucuronidase activity in the neoplastic tissue of stomach was higher than that in the antral and body mucosa, and this enzyme activity in the antral mucosa with intestinal metaplasia was higher than that in the body mucosa of stomach. 2) Lactic dehydrogenase activity in the neoplastic tissue of stomach was similar to that in the antral mucosa with intestinal metaplasia, and was higher than that in the body mucosa of stomach. 3) Acitivities of both enzymes in the neoplastic tissue of differentiated carcinoma were slightly higher than that of undifferentiated one, but did not found statistically significant difference. 4) In the neoplastic tissue of the stomach there was no significant correlation between beta-glucuronidase and latic dehydrogenase activities. Above results support that the measurement of gastric juice enzymes is useful in the diagnosis of stomach carcinoma and may be of value in the identification of high-risk groups.

This study was conducted to determine the level of inflammatory cytokines in the cerebrospinal fluid (CSF) of patients with meningitis. All the CSF of the patients were examined by Gram and acid-fast stain, culture, and PCR for Mycobacterium tuberculosis and Mycoplasrma spp..The levels of sugar, protein and leukocytes count were also evaluated in the CSFs. Concentrations of Interleukin (IL)-1B, IL-6, IL-8, tumor necrosis factor (TNF)-a in the CSF were evaluated by the ELISA kit (Genzyme, USA). General bacteria, tubercle bacilli, and Mycoplasma spp. were not detected with stain and culture methods, but, Mycoplasma spp. was detected by PCR method from four (6.3%) patients with meningitis. The mean CSF concentration of IL-1B, IL-6, IL-8, and TNF-cx in the control group were 0.6+/-0.2, 896.8+/-107.6, 50.1+/-5.1, and 4.8+/-1.4 pg/ml, respectively. The mean CSF concentration of IL-1B, IL-6, IL-8, and TNF-a in the patients with aseptic meningitis were 3.8+/-0.6, 1261.6+/-144.3, 466.7+/-42.3, and 10.8+/-2.0 pg/ml, respectively. The mean CSF concentration of IL-1B, IL-6, IL-8, and TNF-a in the patients with mycoplasmal meningitis were 10.2+/-8.1, 1979.5+/-133.8, 459.7+/-96.4, and 17.5+/-5.1 pg/ml, respectively. There were significantly differences in the levels of IL-1B, IL-6, IL-8, and TNF-a between control and patients with aseptic meningitis or Mycoplasmal meningitis (each p<0.001). These results suggest that increased levels of IL-1B, IL-8, and TNF-a could be higly suggestive of meningitis.

7.A Case of Intracranial Malignant Teratoma.

Korean Journal of Pathology 1990;24(1):85-90
The authors report a case of malignant teratoma in a 3-year-old girl who suffered from occipital headache and vomiting for about 2 months. The tumor occupied left cerebellopontine angle resulting in a moderate degree of hydorcephalus. Histologically, the tumor consisted mainly of neuroepithelial tissues showing varying degrees of differentiation, with areas of epidermis, mature fat tissue, connective tissue, gastrointestinal glands and smooth muscle bundles containing ganglions. Also noted are groups pf polygonal or spindle cells representing immature mesodermal tissue. In contrast to two malignant intracranial teratomas previously reported in Korean literatures, this case is characterized by the presence of predominent neuroepithelial components and by uncommon tumor location, the posterior fossa far from middle line of the body.

Actinomycosis is an indolent, suppurative infection caused by an anaerobic gram-positive organism (usually actinomyces israelii) which usually causes infection in the face, mediastitum, lung, and abdomen. Primary esophageal actinomycosis which is not related with pulmonary or mediastinal actinomycosis, is very rare, especially in immunocompetent host. A 58-year-old woman has been suffered from dysphagia, odynophagia, and chest pain after insertion of esophageal stent in esophageal acid stricture. She underwent a esophagectomy with esophagogastrostomy for above mentioned symptoms. Pathologic diagnosis was a esophageal actinomycosis.

Korean Journal of Pathology 1993;27(3):287-289
The Pleomorphic xanthoastrocytoma(PXA) is considered as a special subgroup of gliomas because of its distinctive characteristics: onset in young subject; predilection for the temopral or parietal lobe and a superficial location; frequent appearance as a yellow encapsulated mass with a grossly visible tumor-associated cyst; marked histological pleomorphism; little or no mitosis and no necrosis; presence of a rich reticulin network; and demonstrable GFAP in many of the fusiform and giant cells; most importantly, the relatively favorable prognosis despite plemorphism and bizzare giant cells in the microscopic picture. The objective of this report is to add one more case of pleomorphic xanthoastrocytoma to the medical literature.
