BACKGROUND: Several keratolytic agents have been used in many dirmatologic conditions such as callus, keratosis palmaris of plantaris, however the evaluation method of the effects of keratolytiic agents has not been good enough in clinical use. OBJECT: We have conducted an investigation to measure the effect of several keratolytic agents using an in vitro model. METHOD: We measured the fegraded protein of keratin by the bui iet method after adding enzymes such as trypsin, pepsin and papain, and irritants, salicylic acid and sodii m lauryl sulfate to the collected callus. RESULT: The order of the keratolytic effect of the enzymes was trypsir >pepsin>papain. It was difficult to detect the keratolytic effect of salicylic acid becaues of color hiidrance and there was an increasing tendency of keratolyti effect of sodium lauryl sulfate, however it was prominent mainly at a high concentration. CONCLUSION: These results suggested that the potency of similar types of keratolytic enzymes such as pepsin, trypsin and papain can be possible. However it was not such a sitable model to check the potency of the keratolytic effect of salicylic acid and the eoncentration tevel may be an important factor for certain kinds of chemicals such as sodium lauryl sulfate.

OBJECTIVES: Cadherin/catenin adhesion complex is fundamentally involved in epithelial cancer invasion and metastasis. E-cadherin and EGFR colocalize on the basolateral membrane of epithelial cell and EGF down-regulate E-cadherin expression. In the invasion and metastasis of cancer, E-cadherin expression is decreased and growth factors receptor is overexpressed. The present study was aimed to find the role of E-cadherin, beta-and gamma-catenin, growth factors and its receptors in cervical cancer cell lines. METHODS: The cervical cancer cell cultures were treated with different time duration of EGF 30 ng/ml and TGF-a 10 ng/ml(0, 10 min, 20 min, 30 min, 1 hr, 2 hr, 4 hr, 8 hr, 24 hr). The change in cancer cell morphology and the changes in E-cadherin, beta- and gamma-catenin, EGFR and activated EGFR expression were studied with a western blot analysis and an immunoprecipitation. RESULTS: Through a western blot analysis, E-cadherin 120 kDa band and EGFR 170 kDa band were expressed in CaSki, HT-3 and ME-180 cell line, which showed epithelial contact growth. 1n these 3 cell lines, expression of E-cadherin did not decrease with time dependent manner. after the treatment of EGF and TGF- alpha. The expression of EGFR decreased and activated EGFR expression increased in 30 minutes to 1 hour but decreased subsequently. When the cells treated with EGF, there were no change in beta-and gamma-catenin expression with there dependent manner. The tyrosine phosphorylation of beta-and gamma-catenin increased in 30 minutes to 1 hour but decreased subsequently with activated EGFR. CONCLUSION: This study showed that an activated EGFR which has involved with tyrosine phosphorylation of beta- and gamma-catenin influenced by growth factors rather than expression of E-cadherin, has a role in the invasion and metastasis of the cervical cancer.

OBJECTIVE: To evaluate the significance of atypical squamous cells of undetermined significance(ASCUS) by following-up cervical cytologic smears or histologic finding. METHODS: Two hundred fifty three cases were diagnosed as ASCUS on cervical cytologic smears from January, 3, 1997 to september, 16, 1998 at cytopathology laboratory, College of Medicine, Keimyung Univemity. These cases were evaluated by cervical smears or subsequent biopsies. RESULTS: The results were as follows, On repeat cervical smears, inflammation was 19.7%, normal was 11,1% and HSIL was 1.6%. On histologic diagnosis, CIS was 13,4%, cervicitis was 12,6%, invasive cervical cancer was 4.0%, and severe dysplasia was 3.2%. CONCLUSION: A diagnosis of ASCUS on smears need careful follow-up.

Vasoconstrictive effect of several topicsl corticosteroids was measured using laser Doppler flowmeter. Hydrophilic ointment base, 1% hydrocortisone cream, 0.1% clocortolone pivalate cream, and 0.25% desoxymethasone cream were applied on both forearms of 20 volunteers. To augment the vasoconstrictive effect of the corticosteroids, We had cut off the blood flow to forearms for 4 minutes by tourniquet. The reactive hyperemia was measured by laser Doppler flowmeter and the ares under the curve were calculated by digitizer aided by a computer. The mean areas of esch drugs were in the following order : hydrophilic ointment base, 0.1% clocortolone pivalate cream, 1% hydrocortisone crearn and 0.25% desoxymethasone cream. However, the standard deviations were too large for the difference to be statistically significant. We concluded that laser Doppler flowmeter is not suitable for the measurement of vasoconstrictive effect of corticosteroid.

The paratertiary butylphenol formaldehyde resin (PTBP-FR) is commonly used as a shoe adhesives because it sticks rapidly, is durable and pliable, and maintains good bond strength at raised temperature. We report two cases of allergic contact dermatitis due to PTBP-FR-containing shoes. Two women visited our department because of the skin rash on their .

OBJECTIVE: The purpose of this study was to assess the role of HPV 16 and 18 in adenocarcinoma in situ(ACIS) of the uterine cervix. METHODS: Seventeen cases of primary cervical adenocarcinoma in situ were analyzed for HPV DNA by polymerase chain reaction. HPV 16 and 18 DNA extracted from formalin-fixed, paraffin-embedded histologic tissue sections by polymerase chain reaction. RESULTS: 35.3% and 23.5% of ACIS were positive for HPV 16 and HPV 18 DNA, respectively. From the normal tissue, 11.8% were positive for HPV 16. Human papillomavirus positive patients were younger than negative patients but statistically insignificant(mean age 42.1 vs 51.7 years). CONCLUSIONS: These results show that HPV type 16 and 18 were closely related to etiology of the ACIS of the uterine cervix.

PURPOSE: This study was to testify the effects on self esteem and spiritual well-being of holistic hospice nursing intervention program ("Rainbow program") for inpatients of hospice palliative care unit. This was designed as a preliminary experimental study with one-group pre-post test. METHODS: A total of 27 patients who were over 18 years old, and admitted in hospice palliative care unit of S hospital in P city, submitted informed consent for this study, participated in holistic hospice nursing intervention program(total 10 sessions and 1,200 minutes for 2 weeks) from April 6, 2004 to April 20, 2005. To test the effects of this intervention, Self Esteem Questionnaire (SEQ) and Spiritual Well-being Questionnaire were used. The collected data were analyzed by Paired t-test with SPSS/WIN 12.0 program. RESULTS: (1) Hypothesis No. 1 "The experimental group which received Rainbow program will have a higher degree of self esteem than before" was supported (t=11.554, P<0.001). (2) Hypothesis No. 2 "The experimental group which received Rainbow program will have a higher degree of spiritual well-being than before" was also supported (t=6.387, P<0.001). CONCLUSION: This Holistic Hospice Nursing Intervention Program was effective in increasing self-esteem and spiritual well-being of patients in hospice palliative care unit. Therefore, it can actively be used and also applied to hospice palliative care practice, research, and education as a useful model of interdisciplinary team approach by hospice professionals.
