Teratocarcinoma is a form of mixed germ cell tumor composed of a mixture of teratoma and embryonal carcinoma. It is rarely found in the brain, but when present it is most commonly found in the pineal region. We investigated a case of primary teratocarcinoma in the pineal region. The patient was a 10 year old boy who had suffered from a bitemporal headache for one month. Brain CT and MRI revealed a rather well defined ovoid heterogenous mass in the pineal gland region, measuring 4.3 x 3.8 x 3.0 cm in size. Microscopically the tumor contained areas of immature teratoma and embryonal carcinoma. Immunohistochemical staining revealed positive reactions for cytokeratin, epithelial membrane antigen, carcinoembryonic antigen, and alpha-fetoprotein in the embryonal carcinoma component.

For the purpose to define the clinical usefulness of fasting serum total bile acid, the authors carried out to measure the serum total bile acid in 18 cases of acute hepatitis, 10 cases of chronic active hepatitis, 21 cases of liver cirrhosis, 7 cases of hepatocellular carcinoma and 35 cases of adult healthy control. Diagnosis were confirmed histopathologically in all the patients. Blood samples were obtained usually in the morning before meals from th anterior cubital vein of all the patients and adult healthy control in Pusan National University Hospital during the periods from January to August, 1984. Total bile acid was measured fluorome cally by means of an enzymatic technique. The results obtained were as follows: 1) The mean value of serum total bile acid in adult healthy subject in fasting was 2.6+/-2.3 umol/L. 2) The mean values of serum total bile acid were significantly higher in the patients with various liver diseases, as compared with those in adult healthy subjects. 3) In acute hepatitis and chronic active hepatitis, the percentages of abnormal values were significantly higher or tended to be higher in total bile acid, as compared with those in total bilirubin, ALP, LDH and GGT activity and tended to be lower in total bile acid, as compared with those in AST and ALT activity. 4) In liver cirrhosis and hepatocellular carcinoma, the percentages of abnormal values of total bile acid were significantly higher in the patients with above 100IU/L of AST activity, compared with those in the patients with 50~100IU/L of AST activity. 5) Total bile acid showed a significant correlation with total bilirubin and ALP in acute hepatitis, with total bilirubin in chronic active hepatitis and hepatocellular carcinoma, and with ALP in liver cirrhosis. On the basis of the results obtained, it was suggested the measurement of serum total bile acid is clinically a highly sensitive, useful test in diagnosis of various liver diseases.

Abnormalities in the number and function of platelets may contribute to thromboembolic complications in patients with essential thrombocythemia(ET). Physicians often use hydroxyurea which reduces the platelet count for the initial treatment of ET. A 74-year-old man with ET was presented with headache, dysarthria, and right hemiparesis 10 months after discontinuation of hydroxyurea. Initial platelet count was 450x103/microliter and we gave him heparin. However, his platelet count rised upto 1,019x103/microliter within 4 days. He was on hydroxyurea 1.5 g/day and his symptoms improved with decrease of platelet count. We report a case of left MCA(middle cerebral artery) multifocal infarction in ET after discontinuation of hydroxyurea.

Bcl-2 oncoprotein is being localized to mitochondria and interfering with programmed cell death (apoptosis) independent of promoting cell division in the lymphoid and nonlymphoid cells. The bcl-2 oncoprotein expression has been reported in follicular lymphomas as well as in diffuse non-Hodgkin's lymphoma, leukemia and a variable propotion of Hodgkin's lymphoma cases. Recent evidence suggests that some lymphomas protected from apoptosis is conferred through expression of Epstein-Barr virus(EBV) latent membrane protein which turn to cause upregulation of bcl-2. To define the role of the bcl-2 oncoprotein and EBV in lymphoid malignancy, we tried immunohistochemical studies with anti-bcl-2 antibody and In situ hybridization (ISH) with EBV-encoded small nuclear RNAs(EBER) in the paraffin embedded sections of 46 non-Hodgkin's lymphoma (NHL) cases and 20 Hodgkin's lymphoma (HL) cases. Bcl-2 oncoprotein expression was found in 37 of 46 cases (80%) of NHL with relatively strong cytoplasmic staining, and in 14 of 20 cases (70%) of HL with weak cytoplasmic staining in limited small numbers of RS, Hodgkin and lacunar cells. The widespread presence of bcl-2 oncogene in many different types of both NHL and HL supports that the extended cell survival through overexpression of bcl-2 gene protein may be a growth advantage of neoplastic lymphoid cells. In the ISH analysis for EBV, the presence of EBV was detected in 17 of 20 cases (85%) of HL, compared to 6 of 44 cases(13.6%) of NHL. It appears to be no direct correlation between overexpression of bcl-2 oncoprotein by neoplastic lymphoid cells and the presence of EBV in NHL but it seems to be a definite association between EBV and HL.
7.The Effects of Taste Preferences on Nutrients Intake and the Degree of Dental Caries in Preschool Children.
Korean Journal of Community Nutrition 2003;8(5):631-641
The purpose of this study was to investigate the effects of preschool children's taste preferences on their intake of nutrients and the degree of dental caries. The subjects were 126 preschool children (boys 62 and girls 64) in Daegu area. Their taste preferences and food intake were investigated and their teeth were also examined. The energy intake of boys (1550 kcal) were significantly higher than that of girls (1441 kcal). Daily dietary intakes of nutrients-except niacin and vitamin C-were higher than those of RDA. Vitamin B1 intake of the group preferring a salty taste was significantly lower than that of the other group (p < 0.05). Vitamin B2 intake of the group preferring a salty taste was significantly higher than that of the other group (p < 0.05). Vitamin C intake of the group preferring a hot taste was significantly higher than that of the other group (p < 0.05). The group with a preference for sweet had more experiences of dental caries and more decayed teeth than the other group, but which is not significant. The experiences of dental caries were negatively correlated with protein intake (p < 0.01). The decayed teeth were negatively correlated with energy and protein intakes (p < 0.01). Our data suggested that taste preferences are associated with vitamins intake and the degree of dental caries in preschool children. It means the sweet preference increased the experiences of the dental caries.

Fibro-osseous pseudotumor is an extremely rare benign lesion which is fast-growing and painful. It is often misdiagnosed as a malignancy, but it is a noninvasive entity and can be cured by simple resection. We report a case of fibro-osseous pseudotumor of the distal phalanx of great toe in 20-year-old female patient who present with painful mass.

This report presents an unusual case of primary malignant melanoma in the midesophagus. The patient was a 36-year-old woman presenting with dysphagia and odynophagia. The resected esophagus and proximal stomach showed a dark purple large polypoid mass, measuring 6.0 3.3 2.0 cm, with a diffuse tan pigmentation of surrounding mucosa in the mid-esophagus and two small daughter nodules, up to 1.2 0.3 cm, in the lower esophagus near the gastro-esophageal junction. A microscopic examination revealed a malignant melanoma of epithelioid cell type confined to mucosa and submucosa with a diffuse melanosis. Cytoplasmic immunoreactivity for HMB 45 and S-100 protein were noted. An electron microscopic examination revealed large, loosely cohesive variable shaped cells with a few cytoplasmic premelanosomes.

10.A case of uterine tumor resembling ovarian sex-cord tumor with clinical review.
Korean Journal of Obstetrics and Gynecology 2002;45(2):303-306
Uterine tumor resembling ovarian sex-cord tumor (UTROSCT) were first described by Clemen and Scully in 1976. They are a heterogenous group of uterine neoplasm characterised by pure or predominant histological patterns that resembled sex cord tumors of ovary. Clemen and Scully divide the tumors into two groups according to sex-cord-like structures within tumors (the so-called group I tumors with 50% of sex-cord elements, the so-called group II tumors with almost completely sex-cord-like structures). The histogensis of the sex-cord-like elements is uncertain, the group I tumor appears to be more malignant. We experienced a case of UTROSCT in a 44 years old woman underwent LAVH under tantative diagnosis of uterine myoma and report the case with brief review of literature.
