BACKGROUND: Basal cell carcinoma(BCC) is the most common tumor of light-skinned people. Most of them are relatively innocuous, but some may cause extensive tissue destruction, and result in death by local infiltration of vital structure or metastatic disease. The bcl-2 is a protooncogene involved in tumorigenesis by blocking apoptosis or programmed cell death. OBJECTIVE: To investigate whether there was a difference in bcl-2 expression in different histopathological types of BCC. Method: We performed immunohistochemical staining by using a monoclonal mouse anti-human bcl-2 oncoprotein in 28 BCC(nodular: 7 cases, micronodular; 3 cases, adenoid; 1 case, infiltrative; 9 cases, and mixed; 8 cases). Result: All 28 BCC expressed bcl-2, and the degree of staining was different according to histopathological types; poor prognostic micronodular(100%) and infiltrative(73.3%) types were relatively strong, and nodular(66.7% ) and adenoid(75.0%) types were moderate. Conclusion . These results suggest that the degree of bcl-2 expression in BCC seems to be dependent to the histopathological types together with clinical behavior.

DNA isolated from human tumor cells can induce malignant transfarmation of tissue culture cells. The DNA is then called an oncogene. Its protein produets have been detected in animal and human tumors and are considered to play a significant role in carcinogenesis. In order to evaluate whether the oncogenes are involved in development of tumors of epidermis and whether they could be used as tumor markers, immunoperoxidase staining was performed for the ras product in sections of squamous cell carcinoma, Bowen's disease, actinic keratosis, keratoacanthoma and seborrheic keratosis. Three cases of sgamous cell carcinoma showed 10~20 positive cells per high power field(HPF). Three cases of Bowen's disease revealed 1-9 positive cells per HPF, whereas the actinic keratosis 1~9 or no positive cells per 10 HPF in all three cases. The keratoacanthoma and seborrheic keratosis showed 1~9 or no positive cells in all observed cases. The positive staining was observed in the cytoplasm. The increasing positivity in parallel with the increase of malignant potential strongly suggests that the ras oncogene is closely related to development of epidermal malignancy and also point out the possibility of ras as a cancer marker.

BACKGROUND: Among 5 subfamilies of dopamine receptors (DAR), D3 and D5 DAR are expressed on peripheral blood mononuclear cells (PBMC). Recently, those DARs have been reported to change in Parkinson's disease (PD). METHODS: We measured the DAR mRNA expression in PBMC from 15 PD patients who had never taken antiparkinson medication, and 16 age-matched healthy people by reverse transcription and quantitative competitive polymerase chain reaction. The beta-actin mRNA expression was also measured to evaluate the relative expression of DAR mRNA. RESULTS: The D3 and D5 DAR mRNA expression was not different between patients and controls. In patients, no significant cor-relation was found between DAR mRNA expression in PBMC and clinical variables such as severity and duration of symptoms, and patients' age. CONCLUSIONS: We confirmed the presence of D3 and D5 DAR in PBMC. However, their mRNA expressions were not influenced by the disease process of PD.

OBJECTIVE: Although the prevalence of pulmonary tuberculosis has decreased progressively after the national control program for tuberculosis began, nowadays the number of MDRTB is increasing seriously. MDRTB tends to be poor responsive to current antituberculosis regimens. It is mainly due to poor compliance, high rate of side reaction of secondary drugs, and limitation in number of available drugs. The purpose of present study is to evaluate the clinical features of pulmonary tuberculosis patients admitted in one national tuberculosis hospital and to expose the problems pertaining to current remedies, to increase the treatment efficacy for pulmonary tuberculosis including MDRTB in the end. METHOD: Retrospective analysis of 336 pulmonary tuberculosis patients admitted in National Masan Tuberculosis Hospital was done. Contents of analysis were patients profile, the first diagnosed time and medical institutes, family history, residence, previous treatment history, chief complaints at the time of admission, lesion site on chest X-ray film, combined deseases, side reaction to antibuberculosis drugs, used drugs before admission and the results of drug sensitivity test. RESULTS: The ratio between male and female was 4:1. Age showed relatively even distribution from 3rd to 6 th decades. 64.6% of the patients was diagnosed at public health center. Weight loss was the most common complaint at admission. Bilateral lesions on chest X-ray films were 59.8%. 1 30patients had combined desease, of which DM was the most common(37.7%). 95patients had family history, of which parents were the most common(41.7%). According to the time of first diagnosis, 31 patients were diagnosed before 1980, and after then the number of patients was increased by degrees Residence overwhelmed in pusan and gyung-nam province. 258 patients got previous treatment history, of which 112 patients(43.4%) had more than 3 times and only 133 patients(51.6%) got regular medication. 97 patients used more than other 3 drugs in addition to INH, EMB, RFP and PZA before admission. 154 patients were informed with the results of drug sensitivity test. of which 77 patients had resistance to more than 5 drugs. Gastrointestinal problem was the most common in side reaction to drugs. CONCLUSION: In the case of weigt loss of unknown cause, tuberculosis should be suspected. In first treatment, sufficient and satisfactory explanation for tuberculosis is necessary and treatment period should not be stict to 6 month-short term therapy. In retreatment, new drugs should not be added to used drugs enen though drug sensitivity restlts show sensitivity to some of them. Proper time for surgical intervention should not be delayed.

Authors performed the immunohistochemical study with avidin biotin-peroxi- dase complex staining on the nail unit of the human fetus for determining the presence of keratin and prekeratin. Seven fetuses, ranging from 12 to 27 weeks in age, were examined. In all cases, the keratin and prekeratin were found in the epidermis of nail units, but not found in stratum corneum and nail plate. Keratin was located predominantly in suprabasal cells whereas prekeratin was located diffusely in the epidermis. Interestingly keratin and prekeratin were found as early as 12 week-old gestational period. There was no significant difference in presence of keratin and prekeratin.

Ranunculus tachiorei is a member of the buttercup family (Ranunculaceae) which contains unsaturated lactone and protoanemonine. Protoanemonine is formed by the breakdown of the glycoside Ranunculin after injury to the plant and causes severe vesiculation and linear streaks after contact with field buttercups(Ranunculus spp.) The amount of protoanemonine in buttercups varies widely with the species of plant and its stage of growth, the highest content being at the time of flowering. We report a case of primary irritant dermatitis due to contact with Ranunculus Tachiorei which was applied for the folk treatment of Bell palsy.

A 27-year-old woman developed Wemicke's encephalopathy in the 16th week of her first pregnaney. She had thyroid storm and abnormal liver function. Her thyrotoxic symptom and abncemal liver function was recovered after medication of antithyroid drug, steroid, hepatotonic drug and administration of thiamine(fursulthiamin), but the fetus was lost, Thereafter her thyroid function returned to normal and euthyroid state was maintained without medication of antithyroid drug, but her neurological defect was remained. We suggest that severe hyperemesis gravidarum is a possible risk factor of the thyroid storm and Wemicke's encephalopathy in patients with hyperthyroidism, and consider the check of the thyroid function. The need for parenteral thiamine supplementation and medication of antithyroid drug is warranted in patients with severe hyperemesis gravidarum which lasts longer than 3 weeks and abnormal thyroid function.
