The incidence of adenocarcinoma of the uterine cervix had shown an increasing tendency, and which is related to the increased use of oral contraceptives or prevalent in human papillomavirus infection. Endocervical glandular dysplasia or adenocarcinoma in situ are occasionally associated with squamous neoplasms of the uterine cervix. This study was aimed to evaluate the histologic features and the incidence of endocervical glandular lesions associated with squamous neoplasms, the presence of human papillomavirus infection-suggesting histologic findings in adjacent squamous neoplasms and the immmunohistochemical findings of endocervical glandular lesions for carcinoembryonic antigen. The materials used were 105 cases of microinvasive and invasive squamous cell carcinoma, and 83 cases of squamous intraepithelial lesions which are consisted of 142 radical or total hystrectomy products and 46 conization or loop excision products. The results are as follows; 1. Among 188 cases, six cases(3.2%) had shown foci of high grade glandular dyaplasia, and 19 cases(10.1%) revealed the areas of low grade glandular dysplasia. There was no adenocarcinoma in situ case. 2. In four of six high grade glandular dysplasia cases, microinvasive or invasive squamous cell carcinomas were associated. In low grade glandular dysplasias, sqaumous intraepithelial lesions were occcupying 68.4%. 3. HPV infection-suggesting histologic findings had accompanied all high grade glandular dysplasia cases and in 17 cases(89.5%) of 19 low grade glandular dysplasias. 4. In 2 of 5 high grade glandular dysplasias and in 1 of 19 low grade glandular dysplasias, the immunohistochemical reaction for carcinoembryonic antigen was similar to that of adenocarcinoma. In conclusion, the clinicopathologic importance of endocervical glandular lesions associated with squamous neoplasms of the uterine cervix should be kept in mind, and further study for the relationship between endocervical glandular lesions and human papillomavirus infection or hormonal influence will be continued.

The effect of androgen in the development of the normal prostate and the evolution of benign prostatic hypertrophy (BPH), and prostatic adenocarcinoma has been proven. In addition to androgen, estrogen and progesterone are also thought to play a role in the pathogenesis of BPH and carcinoma. However, their exact roles are not yet known because there is no conclusive evidence. Thirty cases of prostatic adenocarcinoma and 16 cases of BPH were studied. Immunohistochemical staining for estrogen receptor (ER) and progesterone receptor (PR) in epithelial and stromal cells, respectively was performed and the results were assessed semiquantitatively based on the number of positive cells per 100 total cells. Slides were scored as negative; less than 5% of cells, 1 ; 6~15% of cells, 2 ; 16~25% of cells, and 3 ; more than 26% of cells. The relationship between ER and PR expression and the patient's age, histologic grade, and clinical stage was evaluated in prostatic adenocarcinomas. ER was negative in epithelial and in stromal cells for all prostatic adenocarcinomas and BPH cases. The PR expression in epithelial cells and in stromal cells of BPH was noted in 15 (93.8%) and 16 (100.0%) out of 16, respectively. The PR expression of carcinoma cells and stromal cells in prostatic adenocarcinoma was found in 28 (93.3%) and 23 out of 30 (76.7%), respectively. The PR immunoreactivities of stromal cells around carcinoma were 3 in 18 cases, 2 in one case, and 1 in 4 cases, but those of epithelial and stromal cells of BPH and carcinoma cells of prostatic carcinoma were similar to each other with a value of 3 in most cases. The PR expression rate of stromal cells around carcinoma was significantly correlated with the patient's age (p=0.044), but not with histologic grade and clinical stage. In summary, estrogen does not have a direct effect on the biological behavior of BPH and prostatic adenocarcinoma, but progesterone appears to play a role in the pathogenesis of BPH and prostatic adenocarcinoma. Further studies should clarify the biological role of progesterone in the human prostate.

Detailed mechanism of uterine cervical cancer progression still remains unclear. Altered programmed cell death (apoptosis) and cellular proliferation are associated with the development of neoplasia. The authors investigated the expressions of bcl-2, which inhibit apoptosis, and caspase-3, which is involved in the induction of apoptosis and has been considered to be correlated with apoptosis, and proliferating activity according to the degree of malignancy in the squamous neoplasia of the uterine cervix. Correlation between bcl-2 and caspase-3 expression and proliferating activity was done. The materials were low grade squamous intraepithelial lesions (LSIL, n=15), high-grade squamous intraepithelial lesions (HSIL, n=15), microinvasive squamous cell carcinoma (n=15), and squamous cell carcinoma (n=15). Immunohistochemical stainings for bcl-2, caspase-3, and MIB-1 were done. bcl-2 and MIB-1 expressions were progressively increased in accordance with the increasing degree of malignancy, but caspase-3 immunoreactivity was higher in LSIL than invasive cancers. There was an inverse relationship between bcl-2 and caspase-3 expression, but the difference did not reach statistical significance. No significant correlation between MIB-1, bcl-2, and caspase-3 expressions was observed. These results suggest that an inhibition of apoptosis and the augmentation of proliferating activity of tumor cells might be separately involved in the development of the cervical squamous neoplasia.

PURPOSE: Henoch-Schonlein purpura nephritis(HSPN) accompanied by nephrotic syndrome(NS) is known to have a poor prognosis and effective treatment is still controversial, even though both corticosteroids and immunosuppresant have been used for therapy. Cyclosporine A(CsA) is a well known immunosuppresant and widely used in renal transplantation and glomerular diseases especially steroid resistant. The aims of this study was to evaluate the therapeutic effect of CsA and to compare CsA with previously reported our data of rifampin(RFP) and azathioprine(AZA) in children with HSPN accompanied by NS. METHODS: 37 HSPN patients with NS confirmed by renal biopsy were selected. Of these, 17 patients were treated with CsA(5 mg/kg/day) for 6-8 months, 7 children were treated with RFP(10-20 mg/kg/day) for 9-12 months and 13 patients were treated with AZA(2 mg/kg/day) for 8 months. Along with these regimens, low dose oral prednisolone(0.5-1 mg/kg, qod) was also used. Sequential renal biopsy was done in all patients 1 month after termination of treatment. RESULTS: Complete remission rate of nephrotic syndrome was 5S.8% in CsA, 57.1% in RFP and 38.4% in AZA group after 17, 22, 11 months of mean follow-up period. Overall remission rate including partial remission was 88.2% in CsA, 85.7% in RFP and 84.6% in AZA group. Disappearance rate of hematuria was 58.8% in CsA, 57.1% in RFP and 46.2% in AZA group. Improvement of grade of clinical status was observed in 17 out of 17 CsA, 7 out of 7 RFP and 10 out of 13 AZA group. Improvement of pathologic class on sequencial renal biopsy was shown in 5 CsA(29.4%), none RFP(0%) and 2 AZA group(12.4%). Improvement on histologic immune-deposition was seen in 15 CsA(88.2%), 6 RFP(85.9%) and 4 AZA group(30.8%). CONCLUSION: In conclusion, Both CsA and RFP treated groups showed better result in complete remission rate of nephrotic syndrome and significant inprovement of histologic immune-deposition compared with AZA treated group(p=0.004). So, we recommend CsA and RFP rather than AZA for immunosuppresant treatment in HSPN with nephrotic syndrome.

Cystadenomas are benign neoplasm in which the epithelium demonstrates adenomatous proliferation. Several morphologic variants of cystadenomas have bean described, including papillary-oncocytic, mucous, and seromucous subtypes. Cystadenomas arising from salivary glands are very rare and seromucous cystadenoma of parotid gland has not been reported in Korea so far. Cystadenomas of the parotid gland usually Present as asymptomatic slowly growing mass and those of the minor salivary glands produce smooth nodules that may be compressible. We performed a superficial parotidectomy in a patient with a seromucous cystadenoma. This may be the first report of seromucous cystadenoma of carotid gland in Korea.

OBJECTIVE: Diurnal preference is an attribute reflecting whether people are alert and preferring to be active either early or late in the day. It also referred to as chronotype or morningness-eveningness trait. The PER3 genes have been known to influence diurnal preference. In this study, we have investigated the associations between the PER3 gene polymorphisms and diurnal preference in a healthy young population, controlling for the social and environmental confounding factors. METHODS: The participants in this experiment included 299 unrelated medical college students (M=191, F=108), with a mean age of 22.9 years. Diurnal preference was measured by a single administration of the 13-item Composite Scale for Morningness (CSM). Genotyping of the PER3 VNTR (rs57875989) was performed using polymerase chain reaction. A two-tailed alpha of 0.05 was chosen. RESULTS: The mean+/-SD score on the CSM scale for all subjects was 31.90+/-6.39. There was no significant difference in total CSM score between gender groups, although females showed a trend towards higher morningness score. Although PER3 5R/5R showed the tendency towards high CSM scores, there were no significant differences on CSM scores among genotypes and allele status of PER3 VNTR (rs57875989). CONCLUSIONS: We could not confirm that the PER3 VNTR is associated with diurnal preference in a Korean healthy young population. The future studies need to investigate the association between diurnal preference and other polymorphisms of PER3 gene in larger sample of Korean young healthy population.

BACKGROUND: Recent increase in use of the periodic health screening is due to a concern for health. But study of patient's compliance with recommended periodic health screening has not yet been conducted. This study was accomplished to clarify which aspect to be considered in order to increase patient's compliance after health screening. METHODS: This study was done from March 3 to May 15 in 1997 by Hanil health care center, Among 370 workers in a state-run corporation who received health screening tw? years ago, 170 men were advised to receive an additional laboratory test or treatment at the time. They were asked to fill out a questionnaire and were inte?iewed by doctors to evaluate their compliance. 162 of 170 patients(95.3%) were enrolled in the study, except 8 patients who did not answer the questionnaire. RESURTS: The mean age of patients was 54 years. Most of them were technicians and managers, graduated from high school or higher, and had an annual income of at least 35,000,000 won. The disease of requiring an additional test or treatment were in the order of liver disease, hypertension, gastrointestinal disease, urologic disease and abnormal urinalysis. 68 patients(42%) were compliant and 94 patients(58%) were noncompliant. For reasons of noncompliance,27 patients(28.7%) answered "because l had no symptoms", 20 patients(21.2%) answered "because I didn't think I needed the test or the treatment" and 12 patients(12.7%) answered "because I was busy". The factors influencing compliance were analyzed through chi-square or Fisher's exact test. Their compliance was highly related to the patients'insight into the necessity of the test. the existing disease, and the reporting method of the health screening results. It was not associated with the patients'feeling about their health status, the health behaviors such as smoking and drinking, occupational factors, distance from shire homes to the hospital, or the presence of a hospital near home for those who didn't live in Seoul. The independent effect of the factors influencing the compliance was evaluated by means of stratified analysis. The only independent factor associated with the compliance was the patients' insight. The compliance according to diseases was higher than average in hypertension, liver disease, diabetes mellitus and urologic disease, and lower than average in pulmonary disease, gastrointestinal disease, thyroid disease, cardiac disease, opthalmologic disease and abnormal urinalysis. CONCLUSIONS: The most influencing factor related to compliance was the patient's insight into the necessity of the further testing. We should consider a proper way to increase compliance on health screening. Direct counseling, if possible, is recommended following health screening and way to increase patient's compliance utiliging mail report as another.

A wide range of denomination has been used for inflammatory myofibroblastic tumor (IMT). IMT is not entirely homogeneous, even though it shows some overlapping histologic features such as haphazard proliferation of spindle cell and polymorphic chronic inflammatory cell infiltraion. The spindle cell is considered to be of myofibroblastic origin but follicular dendritic cell origin was reported recently. IMT is known as nonneoplastic, aberrant inflammatory response. However, IMT could show local invasion, recurrence, vascular invasion, and malignant transformation, and clonal characteristics and aneuploidy of IMT support the hypothesis that IMT may be a neoplastic process. In order to define the nature of spindle cell of IMT, immunohistochemical stains for smooth muscle actin (SMA), vimentin (VMT), lysozyme, S-100 protein, cytokeratin, CD21 were done. Additional immunohistochemical stains for MIB-1 for proliferating activity and LMP (latent membrane protein) for Epstein-Barr virus (EBV) were done. IMTs were composed of each 2 cases from lung, liver and lymph node and one case from common bile duct, maxillary sinus, bladder and thigh, and were histologically subclassified according to Coffin et al. Nine cases (90%) were positive for SMA and VMT, but no correlation between SMA and VMT immunoreactivity and histologic types was identified. Five cases (50%) were positive for lysozyme and S-100 protein, and histologic type III was negative for lysozyme and S-100 protein, and immunoreactivity for S-100 protein was different according to the histologic subtypes. All 11 cases were negative for CD21 and EBV LMP. MIB-1 labelling index was less than 1% in all cases. In summary, the spindle cell is regarded as myofibroblastic origin rather than follicular dendritic cell origin. Relationship with EBV is not clear, and negligible MIB-1 reaction suggests that IMT might have a good prognosis.

Heat shock protein of 72 kDa (HSP70) has a role in the functional modulation of sex steroid hormone receptors and in p53-associated oncogenesis and inhibits apoptosis associated with bcl-2. However, the exact role of HSP70 in the development of endometrial adenocarcinoma has not been well established. The aim of this study is to evaluate the role of HSP70 in relation with ER, PR, p53 and bcl-2 expressions and apoptosis in benign and malignant endometrial lesions. Immunohistochemical studies for HSP70, ER, PR, p53, bcl-2 and TUNEL method for apoptosis were performed in 30 cases of adenocarcinoma and 30 cases of benign endometrial lesions consisted of each 10 cases of disordered proliferative endometrium (DP), simple or complex hyperplasia (HP), and atypical hyperplasia (AH). There were no significant differences of HSP70 and bcl-2 expression rates and apoptotic index (AI) between DP, HP, AH, and adenocarcinoma. p53 expression rate in adenocarcinoma was 36.7%, but no p53 expression was identified in DP, HP and AH (p<0.05). In adenocarcinoma, HSP70 expression rate was higher in ER and PR negative adenocarcinoma (p<0.05), and p53 expression rate was higher in nonendometrioid type and FIGO grade II and III (p<0.05), but no significant difference of bcl-2 expression rate according to the histological type and FIGO grade. AI was higher in nonendometrioid type (p<0.05). There was no correlation between HSP70, p53 and bcl-2 expressions, and no significant difference of AI according to HSP70, ER, PR, p53, and bcl-2 expressions. In conclusion, higher HSP70 expression rate in poorly differentiated and ER and PR negative adenocarcinoma suggests that HSP70 inhibits ER and PR expression and may be involved in the development of poorly differentiated endometrial adenocarcinoma.
