Atypical condyloma is a variant of flat condyloma characterized by the presence of atypical koilocytes having large hyperchromatic, smudged and often bizarre nuclei. Atypical condyloma can be frequently misdiagnosed on cytologic smear and on tissue sections by its marked cellular atypia, as high grade dysplasia, in situ or even invasive squamous cell carcinoma. We described two cases of atypical condyloma of the female genital tract. The cytologic features and histologic changes were reminiscent of those of invasive squamous cell carcinoma and severe degree of dysplasia of the uterine cervix. The differential findings between atypical condyloma and squamous cell carcinoma were discussed in detail.

PURPOSE: The purpose of this study was to identify the effects of meridian massage on menopausal symptoms and Shin-Hur in middle-aged menopausal women. METHOD: The research design was a nonequivalent control group pre-post experimental design. The subjects of the study were middle-aged women who had had no menstruation in the last 12 months after the last menstrual bleeding. Cards of invitation on bulletin boards of several apartments were placed to recruit the subjects. The cards of invitation included: purpose of the study, eligibility criteria, method and period. Eighteen women in the experimental group and 16 women in the control group were conveniently assigned, respectively. The experimental group received 20 min meridian massage 3 times per week for 4 weeks. The menopausal symptoms and Shin-hur were measured and compared between the two groups before and after the intervention. Data were analyzed with the SPSS program by Fisher's exact test, Wilcoxon Sign Rank test, Mann Whitney U-test and Spearman's rank correlation. RESULT: The experimental group showed a significant decrease of menopausal symptoms (U=77.00, p=.020) and Shin-Hur (U=76.00, p=.017). There was a significantly positive correlation between menopausal symptoms and Shin-Hur (r=.497, p=.003). CONCLUSION: Meridian massage was effective in improving menopausal symptoms and Shin-Hur in middle-aged menopausal women. Thus it can be useful as a nursing intervention for menopausal women.

Twenty-four ma1e a1bino rats were chosen at random and divided into two dietary groups: one for control (diet 1) and the other for an experimental diet (diet 2). Diet II consisted of the basal diet supplemented with red pepper powder in increasing amounts from 1.25%, 1.8% and 2.5% to 3.6%. With a red pepper diet at the 2.5% level, there was a significantly lower efficiency of food utilization. (p=0.05) The apparent digestlbility of calcium with red pepper concentrations from 2.5 to 35% was about 13% greater than in tile control diet. Thus red pepper appears to affect the solubility of calcium in the diet. Serum alpha-Carotene and Vitamin A showed a tendency to increase slightly with a red pepper diet. No histological changes in the gastric mucosa cells were observed in rats fed a red pepper diet. Further investigation is required to define the effects of red pepper in different species of animals.

In the field of the experimental lung transplantation, we analyzed the CT findings of acute rejection, infection in the left single allotransplanted lung of adult mongrel dogs, and the CT findings were compared with the histological findings obtained by the lung biopsy. Twenty two adult mongrel dogs were divided into two groups(Donor and recipient group). Donor lungs were flushed with LPDG(low potassium dextran glucose) solution(n=4) or modified Euro-collins solution(n=7) and preserved over 20 hours with 10degrees C(1 case preservation for 4hours). After left single lung transplantation, the chest X-ray and sequential computed tomogram were performed with concomitant hemodynamic study and arterial blood gas analysis on immediate postoperative period, postoperative 3rd day and postoperative 7th day. Two of eleven transplanted lungs had acute rejection which was represented as moderate infiltration at immediate or 1st postoperative day but became extensive infiltration at postoperative 3rd day on CT. There were showed one case of bronchopleural fistula, six cases of pneumonia and two cases of pulmonary infarction. In one rejection cases, the opacity of transplanted lung was improved by injection of methylprednisolone 500mg daily during 3 days. We concluded that CT was a useful noninvasive evaluation parameter after lung trans- plantation and the serial CT scan enabled early detection of acute rejection.

PURPOSE: Protein and energy malnutrition are common in patients with stomach cancer. Nutritional assessment is of great importance because undernutrition has been shown to be associated with increase morbidity and mortality in stomach cancer. METHODS: The study subject were 88 patients with stomach cancer admitted at Kosin university Gospel Hospital General Surgery Department during August 2001 to December. We assessed the initial nutrition status by anthropometric, biochemical and dietary intake data along with subjective global assessment (SGA) and stomach cancer stage. RESULTS: The mean body index was under weight, body fat mass and body protein mass were decreased with increase cancer stage. The biochemical data of albumin, cholesterol, triglyceride, Zn, transferrin, total lymphocyte count were decrease with increase cancer stage. Daily energy intake was 1997.8 kcal, energy, cabohyderate and VitB 1 was decrease with cancer stage. The patient were divided into three groups according to SGA. The three groups showed a significant difference in body weight, 1 month weight loss %, 6 month weight loss %, body mass index, mid arm circumference, albumin, energy intake, as well as carbohyderate intake CONCLUSION: The author concluded that nutritional assessment should be done in cancer patients preoperatively and that with adequate nutritional support, the morbidity and mortality would be decreased. Our data show that SGA is a clinically adequate method for assessing nutritional status.

To compare the stem niche in different culture conditions of limbal epithelial cells, the suspended human limbal epithelial cells (HLECs) were seeded on the 3T3-pretreated plates and the other suspended cells were plated on amniotic membranes (AMs) which were either cryo-preserved or freeze-dried. All were cultured for 10 to 12 days. Reverse transcription-polymerase chain reaction (RT-PCR) for ATP-binding casette, subfamily G, member 2 (ABCG2), p63, cytokeratin 12, and connexin 43 were performed in cultivated HLECs and their expression levels were compared. The mRNA expression of all markers examined showed no statistically significant differences between the cells on cryo-preserved and on freeze-dried AM. The expression of p63 and cytokeratin 12 in cultivated cells on AMs were significantly lower than those in 3T3-cocultured cells on RT-PCR and immunofluorescent staining. Cultivated HLECs on AMs showed reduced proliferation and differentiation while maintaining stem-property regardless of the preservative method of AM.

PURPOSE: To investigate methods of isolating putative corneal epithelial stem cells from cultured limbal tissue. METHODS: Three extraction techniques were compared to identify an efficient method of obtaining a large number of viable corneal epithelial stem cells from the limbus. Limbal tissues were extracted by incubation at 37 degrees C or 4 degrees C for 1 or 16 hours, respectively, with 1.2U/ml dispase/trypsin or by treatment with 0.05% trypsin and 0.01% ethyldiaminetetraacetic acid (EDTA) at 37 degrees C in single procedure. Collected cells were cultured on NIH/3T3-seeded plates, and colony forming efficiency (CFE) was evaluated. Fluorescence activated cell sorting (FACS) was performed with a Coulter EPICS 753 after incubation with Hoechst 33342 and propidium iodide (PI). Hoechst negative cells were obtained using gates exhibiting low Hoechst blue with a 424/44 nm BP filter. Gated cells of each fraction were re-cultured to assess the capability of colony formation. RESULTS: The mean numbers of viable cells obtained from treatment with dispase and trypsin was 3x10(4) cell/ml and 8.06x10(5) cell/ml at 37 degrees C and 4 degrees C incubations; the number increased to 1.21x10(6) cell/ml with a trypsin/EDTA treatment (p<0.05). CFE was 9.67+/-2.13% and 6.63+/-2.35% in rabbit and human cells, respectively. Likewise, the Hoechst negative fraction was 3.61+/-0.42% and 5.21+/-4.91% in rabbit and human cells, respectively. The sorted Hoechst negative cells were cultured through four passages, forming small round colonies. In rabbit cells, the CFEs of Hoechst negative and positive fractions after FACS, were 12.67+/-2.24% and 1.17+/-6.13%, respectively (p<0.05). CONCLUSIONS: Putative corneal epithelial stem cells were efficiently isolated from limbal tissue using a trypsin/EDTA extraction and FACS. This technique may be very useful in tissue engineered stem cell therapy.

PURPOSE: To analyze the isolating pattern of slow cycling cells as putative limbal epithelial stem cells (PLESCs) using Hoechst exclusive cell sorting. METHODS: Rabbits were injected with 5-bromo-2-deoxyuridine (Brd U) 1 month prior to be sacrificed. After obtaining limbal tissues, fluorescence-activated cells were sorted on a Coulter EPICS 753 after they had been incubated with Hoechst 33342 and propidium iodide. Two different methods were applied to sort PLESCs. Side-population(Sp) cells were obtained using gates with dichroic mirror to detect low Hoechst blue and red after verapamil was treated. Hoechst negative cells were obtained using gates exhibiting low Hoechst blue with a 424/44 BP filter. Brd U-retaining cells were counted and their sizes were evaluated in each gated sample to compare isolating pattern of PLESCs in each method. RESULTS: The percentages of Sp cells and of the Hoechst negative fraction were 0.96 +/- 0.79% and 16.01 +/- 13.60%, respectively(p=0.021). Homogeneity and density of the small cells were higher in Hoechst negative fraction than in Sp cells. The percentage of Brd U-retaining cells was 47.36 +/- 10.34% and 47.14 +/- 14.94% in Sp cells and Hoechst negative fraction, respectively(p>0.05), and they were 10 times higher than in non-Sp and Hoechst positive fraction(p=0.000). CONCLUSIONS: Hoechst negative exclusion without verapamil more efficiently isolated PLESCs than Sp did.

A thermal neutron beam facility utilizing a typical tangential beam port for Neutron Capture Therapy was installed at the HANARO, 30 MW multi-purpose research reactor. Mixed beams with different physical characteristics and relative biological effectiveness would be emitted from the BNCT irradiation facility, so a quantitative analysis of each component of the mixed beams should be performed to determine the accurate delivered dose. Thus, various techniques were applied including the use of activation foils, TLDs and ionization chambers. All the dose measurements were performed with the water phantom filled with distilled water. The results of the measurement were compared with MCNP4B calculation. The thermal neutron fluxes were 1.02E9 n/cm2 s and 6.07E8 n/cm2 s at 10 and 20 mm depth respectively, and the fast neutron dose rate was insignificant as 0.11 Gy/hr at 10 mm depth in water. The gamma-ray dose rate was 5.10 Gy/hr at 20 mm depth in water. Good agreement within 5%, has been obtained between the measured dose and the calculated dose using MCNP for neutron and gamma component and discrepancy with 14% for fast neutron flux. Considering the difficulty of neutron detection, the current study support the reliability of these results and confirmed the suitability of the thermal neutron beam as a dosimetric data for BNCT clinical trials.
