We immunized sixty two healthy subjects with the five different viral titers (300, 500, 1000, 1500 and 2000 plaque forming unit; pfu) of the MAV/06 strain of live attenuated Varicella-zoster virus (VZV) in order to gain sufficient information on safety and immuogenicity as a vaccine strain. Humoral immunity of all vaccine recipients was tested by the fluorescent antibody to membrane antigen (FAMA) assay and Enzyme-linked immunosorbent assay (ELISA) for the quantitative detection of IgG antibody. We tested neutralized antibody in 62 subjects by plaque reduction neutralization test (PRNT50). All of thirty two subjects with initial seronegative response had antibody by FAMA method at four weeks after immunization with four different preparations of dosage. The geometric mean titers (GMTs) of VZV antibody to membrane antigen was 160.9 in 6 subjects with 1500 pfu group; 83.3 in 14 subjects with 1000 pfu group: 116.2 in 7 subjects with 500 pfu groups and 72.0 in 6 subjects with 300 pfu group. Thirty subjects who had VZV antibody at the time before immunization demonstrated elevated antibody titer by FAMA assay and PRNT50 test. Side reactions of the vaccination was not demonstrated in all cases.

Though basal cell carcinoma is the most frequent and increasing malignant tumor of the skin in Korea, its pathological analysis has been done only on the small numbers. So, we did a comprehensive pathologic study on the 283 patients with basal cell carcinoma diagnosed in the Department of Pathology, Seoul National(233cases) and Chung-Ang(50cases) University Hospital during 1975-1992. The age distribution was ranged from 15 to 84 years with highest incidence rate in the age group of 5th-8th decades and 83.7% of all patients were over 40 years of age. Sex difference was not noted. The most common site was face occuring in 235 out of 283cases(83.0%) especially in the eyelid(25.5%), nose(17.9%) and cheek(16.6%). The most frequent histopathologic type was solid type(54.0%) followed by mixed(23.9%), adenoid(7.5%), and metatypical(4.7%). Among 51 mixed type, all showed solid components with adenoid(51.0%) followed by morphea(25.5%) and metatypical type(13.7%). And among 14 recurrent cases, solid type is found in 50% of cases. The characteristic clinicopathological findings are solid arrangement of tumor cells with various histological pattern and predominant occurence on the face.

Tumor suppressive effect of dehydroepiandrosterone (DHEA) on the experimentally induced hepatocellular carcinoma was investigated, especially focusing on glutatione transferase and transglutaminase with aptosis in the carcinogenesis. The chemical hepatocarcinogenic procedure of Solt-Farber method was used on Sprague-Dawley rats. Experimental groups were divided into AA group treated by the standard Solt-Farber regimen of diethylnitrosamine (DEN) and 2-acetamidofluorene (AAF) and AD group treated with DHEA simultaneously with AAF and the AAD group treated by DHEA after treatment with AAF. Each group was divided by time sequence further into four subgroups, GI (8wk), G2 (16wk), G3 (28wk), and G4 (36wk). For neoplastic lesion, the immuno histochemical study with anti GSTP antibody was carried out, while the activity and expression of TGase was compared at the same time. The results were summarized as follows; GST-P positive foci detected in AD groups were significantly more suppressed by DHEA treatment than AA groups (P<0.05). AD groups. AD group showed higher activities of TGase than AA groups (P<0.05), which was confirmed by Western and Northern blot analysis. But the number of apoptotic bodies was not correlated with activity and expression of TGase in the nodule. These results suggest that the suppressive effect of DHEA on the murine hepatocellular carcinogenesis might be operating on the promotion process of carcinogenesis rather than regression process of transformed hyperplastic nodules.

We report a case of cutis verticis gyrata-mental deficiency syndrome associated with generalized epidermal nevus. The clinical features of the patient included severe mental retardation, drug resistant epilepsy, short stature, scaphocephaly and dysmorphic face with scanty scalp hair, hypertelorism, long palpebral fissure, low nasal bridge, hyperplasia of ala nasi, low-set ears with convoluted fold, and partial obstruction of the nasolacrimal ducts. Multiple convoluted folds and furrows on the scalp were extended to eyebrows and nose. Both lateral ventricle with periventricular leukomalacia were dilated markedly and the corpus callosum was hypoplastic on brain MRI. The nature of the yellowish brown colored elevated skin nevi on the whole body was consistent with systemic epidermal nevus by pathological study.

Hailey-Hailey disease is a rare hereditary dermatosis that begins in the 2nd or 3rd decade of life. The skin lesion is characterized by a localized, recurrent eruption of small vesicles on an erythematous base. It courses remissions and exacerbations. It seldom begins in early childhood, and main treatment modalities are conservative ones. We report a case of Hailey-Hailey disease that began on a 7-month old infant and improved by surgical treatment. In according to review of the previous reports, it is probably the earliest onset age and it is may be the first case which was treated with surgery in Korea.

Rabies is a fetal viral encephalitis to which all mammals, including man are susceptible. This virus, the genus of Rhabdovirus, is usually present in the saliva of infected animals and is transmitted by their bite. As a rule the virus enter the CNS by ascending along peripheral nervous system and extremely variable in extent. Negri bodies are appear in about 75% of cases. These bodies are eosinophilic, usually rounded inclusions and is located in the cystoplasm of the neurons, most frequently in the pyramidal neurons of the Hippocampus and the Purkinje cells of the cerebellum. We have experienced a case of canine rabies that showed Negri bodies in the Purkinje cells along with diffuse degenerative encephalitis and perivascular mononuclear cells infiltration. The Negri bodies were best demonstrated by Negri body staining although routine H-E staind was also useful. There inclusion bodies were located exclusively in the cytoplasm, and were found occasionally. Electron microscopic findings of the Negri bodies showed aggregates of bulletshaped nucleocapsids. We report a Negri body found in the brain of rabid dog with the light and electron microscopic findings.

The problem of carbon monoxide intoxication has been increasing since 1950s and it is still regarded as one of the most serious public health problem in Korea. If the patients survives the acute episode, elimination of carbon monoxide occurs in the rate of a halt-time of 3 to 4 hours. Nevertheless, there may remain after effect. Therefore, the present study was desinged to elucidate the change of myocardial tissue caused by acute carbon monoxide poisoning were evaluated by electrton microscopic observation of the severity of the mitochondrial swelling and cytochrome oxidase activity, which was demonstrated by histochemical staining with diaminobenzidine(DAB). Male Sprague-Dawley rats were exposed to the carbon monoxide of 1500 ppm for 150 minutes. They were divided into two groups ; one group were treated with hyperbaric oxygenation 15 minutes after carbon monoxide exposure, the other were not treated. Rats were sacrified 6 hours, 12 hours, 1 day, 3 days, 7days, 14 days, and 21 days after carbon monoxide exposure. The specimens were collected from the apex of the heart. In the group without hyperbaric oxygenation, mitochondrial swelling subsided 21 days after carbon monoxide exposure accompained by restoration of cytochrome oxidase activity. On the other hand, with hyperbaric oxygenation, healing process was shortened. Cytochrome oxidase activity was restored 7 days after carbon monoxide exposure.

BACKGROUND: Evening primrose oil(EPO) is a rich source of cis-linoleic acid and gammalinolenic acid(GLA) and has been used as a therapeutic agent in various skin diseases such as atopic dermatitis. OBJECTIVE: The purpose of this study was to evaluate the suppressive effect of EPO on murine contact sensitivity. METHODS: BALB/c mice were divided into 3 groups, positive control, experimental and negative control groups: the positive control group represents a group of mice which were sensitized and challenged with DNFB, the experimental group represents EPO-pretreated positive control group and the negative control group represents a group of mice which were challenged only. The changes of ear thickness were measured, and H & E staining and immunohistochemical staining for ICAM-1 expression of ear skin were performed to evaluate the histological changes of each group. RESULTS: The Pretreatment of mice with EPO resulted in suppression of contact sensitivity by more than 82%. On H & E staining, only a mild inflammatory reaction was observed in the dermis. Also ICAM-1 expression of keratinocytes, the intensity of the staining was significantly decreased in the experimental group compared with positive group. CONCLUSIONS: Our study indicates that EPO was able to suppress the induction of contact sensitivity.

Authors experienced a rare adenocarcinoma arising in presacral sacrococcygeal teratoma in a adult and herein reported. The patient was a 52 year old female admitted because of lower abdominal pain for 5 to 6 months. Past and familial history were unremarkable. On rectal examination a mass was palpated 3 cm above the anal verge. The large bowel was displaced by an extrinsic mass but there was no evidence of intrinsic tumor lesion on barium enema, CT was done and showed a large presacral tumor attached to the sacrum. Clinical impression was sacrococcygeal teratoma. Resected tumor mass was a relatively well circumscribed cystic mass, measuring 11 x 11 cm and the cystic content was previously evacuated. Inner surface showed ragged appearance, and focal nodular solid area was noted. On microscopic examination, the tumor revealed the derivatives of three germ layers and main components were tissues of respiratory tract. Sections from the solid area showed a well differentiated adenocarcinoma and with stromal, capsular and perineural invasion. Borderline malignant epithelial lesions are also noted suggesting the pathogenesis and progression of this tumor. There was no recurrence for one year after surgery in the follow up.
