BACKGROUND: It is well-known that the giant congenital nevi prcgress to malignant, melanama more frequently than other benign melanocytic nevi but to date the laor tory methods for early detection of such progression were not avsilable. The proliferating cell uncleai antigen(PCNA) staining has been regsrded as an useful marker in determining prognosis of some maignant diseases. OBJECTIVE: The PCNA taining was performed as a predictive value of malignant transformation from benign meanocytic skin lesions. We investigated the differcnces between malignant melanoma and the benign lesions. MATERIAL AND METHODS: Immunohistochemical study was employee using anti-PCNA, anti-S-100, and anti-CD45RO antibody in 6 giant congenital nevi, 8 small and medium sized congenital nevi, 10 acquired nevi, and 10 malignant meanomas. Only cells positive for both PCNA and S-100, and negative for CD45RO on the serial sections were identified as melanocyts. RESULTS: The number of PCNA-posit,ive cells per 1000 melanocy,es averaged 6.0+7.5 in giant, congenital nevi, 2.9+1,9 in small and medium sized congenital novi, 3.1+2.7 in acquired nevi, and 61.5+ 39.4 in malignant, melanomas. Malignant melanomas showed onger intensity of PCNA staining than the other melanocytir nevi. CONCLUSION: There was not significant difference of the numter of PCNA-positive cells among the groups of congenital neviind PCNA staining can't be used in prditive measure of malignant. progression and studying mechansm of malignancy in giant congenital nevi. But, PCNA staining is considered as an useful method in differentiat,ing malignant melanoma from mllanocytic nevi.

This study was performed to observe the effect of ultrasound(1.0MHz, 0.75W/cm2 and 1.0W/cm2) irradiation on cultured MC3T3-E1 cell, osteoblastic like cell with respect to the proliferation, protein synthesis, and alkaline phosphatase activity of the cells. The results were as follows: 1. The proliferation of MC3T3-E1 cells was increased on ultrasound irradiated group compared with control group. 2. The protein synthesis was not apparently increased on ultrasound irradiated group compared with control group. 3. The alkaline phosphatase activity level was not apparently increased on ultrasound irradiated group compared with control group. From the above results and other literatures, we could suggest that the ultrasound with the appropriate intensity and frequency may have important roles in stimulation of cell proliferation. Therefore the ultrasound may be used in the acceleration of the bone regeneration and bone fracture healing.

BACKGROUND: There are many rating scales for assessment of geriatrics. But each of these scales were not sufficient to evaluate comprehensive geriatric assessment, physical and psychologic efforts for care. METHODS: We developed new scales to comprehensive geriatric assessment for care of geriatric patients. The Geriatrics Physical Support Scale(GPSS) evaluates physical effort consists of 10 areas and the Geriatrics Global Support Scale(GGSS) evaluates general condition of patients consist of 6 areas. Eighty probable and possible AD patients received the Clinical Dementia Rating Rating Scale(CDR), Korearn version of Mini-Mental State Examination(K-MMSE), Barthel Activity of Daily Living Index(B-ADL) GPSS, GGSS. We tested internal consistency, correlation among dementia rating scales. RESULTS: The GPSS correlated to CDR -0.63(p<0.01), B-ADL -0.90(p<0.01) and the GGSS correlated to CDR -0.60(p<0.01), B-ADL -0.75(p<0.01). The internal consistency were 0.69(GGSS), 0.92(GPSS). CONCLUSION: The Geriatrics Global Support Scale evaluate general condition of patients and the Geriatrics Physical Support Scale evaluate physical efforts needed for care of geriatric patients. These scales an also brief and easy rating scales to grade degree of caregiver`s burden.

Trichoblastic fibroma is a rare benign tumor of hair germ with mixed epithelial-mesenchymal components. A 64-year-old female presented with an asymptomatic, skin-colored, firm nodule on the left knee joint. Histopathologic examination showed multiple tumor islands and strands eomposed of basaloids cells embedded in a moderately cellular fibroblastic stroma and the for vation of bud-like extension of tumor cell nest. The peripherel basaloid cells shovred a palisading arrangement and small keratinous cysts were formed in tumor islands.

Benign cystic mesothelioma (BCM) is a rare mesothelial lesion that forms multicystic masses in the upper abdomen, pelvis and retroperitoneum. Although it is categorized as a benign lesion, it has a tendency to recur. It is uncertain whether the nature of this lesion is reactive or neoplastic, but many articles support the conclusion that it is reactive rather than neoplastic. The majority of cases were associated with a history of a previous abdominal or pelvic operation, or an evidence of endometriosis or a pelvic inflammatory disease, or a combination of these findings. In a 26-year-old woman we experienced a case of BCM which was incidentally discovered at cesarean delivery revealing multilocular thin and translucent walled cysts in the pelvic cavity. Microscopic examination revealed a thin cyst wall that was composed of fibrous connective tissue and lined by internal stratified and external nonstratified single cuboidal epithelia.

Background: Desflurane, a fluorinated methyl-ethyl ether, has some advantageous properties including low blood solubility, stability in soda lime, and resistance to biodegradation. Desflurane in vivo has demonstrated myocardial depressant property. The purpose of this study was to test the direct effects of desflurane on myocardial contractile function and coronary flow in the isolated heart. Methods: Twelve isolated rat hearts were continuously perfused with modified Krebs solution containing 6, 9 and 12 vol% of desflurane for 10 min at each concentration. Systolic left ventricular pressure and rate of change of ventricular pressure (dp/dt) were measured. Heart rate and coronary flow were also measured. To differentiate direct vasodilatory effect of desflurane from an indirect metabolic effect due to autoregulation of coronary flow, oxygen delivery, myocardial oxygen consumption and percent oxygen extraction were calculated. Results: Heart rate (control 266+/-22 beats/min) decreased to 250+/-23 beats/min at 6 vol%, 236+/-26 beats/min at 9 vol% and 223+/-22 beats/min at 12 vol% of desflurane. Systolic left ventricular pressure and dp/dt decreased in a concentration-dependent manner. In spite of decrement of myocardial oxygen consumption, coronary flow (control 12.0+/-1.2 ml/min) increased to 12.8+/-1.6 ml/min at 6 vol%, 12.9+/-1.6 ml/min at 9 vol% and 13.7+/-1.4 ml/min at 12 vol% of desflurane. Oxygen delivery increased proportionally with coronary flow. Percent oxygen extraction decreased in a concentration-dependent manner. Conclusion: These results suggest that desflurane has a direct myocardial depressing and coronary vasodilating effect in a concentration-dependent manner.
