Pulmonary lymphangiomyomatosis is a rare disease of haphazard overproliferation of smooth muscle from perilymphatics, peribronchial and perivascular regions of the lung that leads to chylous effusion, hemoptysis, spontaneous pneumothorax and pulmonary insufficiency. The disease only affects women of child-bearing age. There is presently no successful therapy and most of the patients die within 10 years of diagnosis. We experienced a case of pulmonary lymphangiomyomatosis in a 30-year-old woman who had suffered from three episodes of spontaneous pneumothorax for 4 years. Open lung biopsy was performed. Microscopically, abnormal excess proliferation of smooth muscle tissue was identified in the wall of perivascular lymphatic channels as well as around small bronchi, and more distal air spaces. Varying sized cytic spaces Iined by cuboidal cells were also present. Tamoxifen, given if February 1991, did not influence the course of her disease. She died of respiratory failure at age of 31 in April 1991.

Estrogen and progesterone receptors exist in the epithelial and stromal cells of the endometrium. Proliferative disorders of the endometrium may be associated with autocrine and paracrine actions of estrogen and progesterone in epithelial and stromal cells. This study was performed to evaluate the differences estrogen and progesterone receptor(ER/PR) expression in the epithelial and stromal cells of endometrial hyperplasias and adenocarcinomas using immunohistochemical methods. Immunohistochemical analysis of proliferating cell nuclear antigen(PCNA) was done to evaluate a possible correlation between PCNA and hormone receptor expression. Evaluation was based on samples from 31 simple hyperplasias, 30 complex hyperplasias, and 32 adenocarcinomas. The immunohistochemical expression of ER, PR and PCNA in epithelial and stromal cells were examined according to a scoring system based on the percentage of positive cells and the staining intensity. The results were as follows; 1) The expression of ER and PR in epithelial cells showed a graded, significant decreases in simple hyperplasia, complex hyperplasia and endometrial carcinoma, in that order(ER: P=0.008, PR: P= 0.026). 2) PR expression in the stromal cells showed a significant decrease between hyperplasia and adenocarcinoma(P=0.003). The difference in ER expression was not significant. 3) In stromal cells, the decrease in PR expression was more prominent than the decrease in ER expression when complex hyperplasia was compared to simple hyperplasia. 4) The PCNA expression in simple and complex hyperplasia and adenocarcinoma was not higher than the expression of PCNA in nomal proliferative endometrium. There was no significant difference in PCNA expression between simple and complex hyperplasia and adenocarcinoma(P=0.073). 5) A negative correlation between PCNA and ER/PR expression was not demonstrated in simple and complex hyperplasia, or in adenocarcinoma. Endometrial hyperplasia and adenocarcinoma are probably related to a paracrine action of estrogen and progesterone in epithelial and stromal cells. A progressive loss of PR expression in stromal cells may induce abnormal proliferation of endometrium due to a disrupted hormonal balance.

As the morbidity of chronic diseases such as diabetes and high blood pressure has increased, the frequency of oral dryness upon taking drugs for a long time or several drugs at the same time has greatly increased. This study was conducted to investigate the status of oral dryness and utilize the data to develop treatment products. Surveys were assembled from October to December 2018, and a statistical analysis of the 144 responses was conducted. The surveyed consisted of 60 males and 84 females, with 31.3% of those in their 70s and older. Among them, 100 people took drugs for chronic diseases, while 27 people took drugs for more than 10 years and less than 20 years. Exactly 23 respondents who took drugs suffered from more than two types of chronic diseases, of which high blood pressure was the most cited, followed by hyperlipidemia and diabetes. Regarding complications, oral dryness (33.8%) was the most frequent, and there were significant differences in the degree of discomfort when taking medicine, especially for oral dryness depending on the age (P<0.05). Groups that took medicine showed severe symptoms of dry mouth, especially when waking up at night or in the morning (P<0.001) and eating food (P<0.01), and had difficulty in swallowing food (P<0.01) and speaking (P<0.01). Exactly 89.6% of the respondents didn’t take lozenges (candy) for improvement of oral dryness, and the type of the product that they wanted to purchase the most was candy (45.1%). Respondents worried about rising blood sugar, dental caries, and calories when eating candy for relieving dryness (P<0.01).

Condyloma acuminatum is a common viral disease which is transmitted by sexual intercourse. We experienced a case of condyloma acuminatum occurring in a patient of systemic lupus erythematosus who has been treated with various immunosuppressive agents for 10 years. This condylorna acuminatum was unusual in that it was very rapidly growing, recurrent and reluctant to various treatrnents. We investigated the type of human papillomavirus by Southern blot hybridization and schieved partial improvement by bleomycin intralesional injection together with 5-FU topical application.

OBJECTIVE: A number of studies to improve in vitro culture conditions have been tried over past ten years by using co-culture system with helper somatic cells. However, the mechanism of coculture is poorly understood. This study was designed to understand the mechanism for the mode of actual action of co-culture system of ICR strain's 1-cell embryos with human oviduct epithelial cells by examining the effect of conditioned medium and contactless coculture using a cell culture insert on the embryo development and by measuring the level of superoxide anion from conditioned medium after co-culture. METHODS: ICR strain's zygote embryos were cultured in medium alone (control), coculture, conditioned medium, or contactless coculture system for 6 days. Conditioned media (CM) were prepared as following 5 groups. All CM were collected after culturing oviduct cells for 2 days. CM-1 was stored at -20degrees C until use, and CM-2 was prepared just before use as a culture medium. CM-3 was cocultured with embryos and retrieved just before use. CM-4 and CM-5 were derives from the microfilteration of CM-2 and CM-3, respectively, using Microcon-10 (10 kDa molecular weight cut-off). The percentage of the embryos developed to hatched blastocyst stage and the level of superoxide anion in supernatant from medium alone culture (control), coculture, and contactless coculture were measured. RESULTS: The rates of embryo development to the hatched blastocyst stage were significantly higher in coculture (43%) than in control (0%) (p<0.05). The CM-1 group had no embryo development since 2-cell embryonic stage, whereas the CM-2, CM-3, CM-4 and CM-5 groups had the improved development to 4 or 8 cell embryo stage, but the similar rate of development to hatched blastocyst compared to control. The effect of coculture on embryo develpment was disappeared in the contactless coculture group. The level of superoxide anion was significantly reduced in coculture group compared to control. CONCLUSION: It is concluded that the present coculture system overcomes the 2-cell block in vitro and improves the embryo development. This beneficial effect may be due to the direct cell-cell contact between embryo and helper cells or the removal of deleterious components from medium rather than the embryotrophic factors.

BACKGROUND: Calcium channel blockers and volatile anesthetics have depressant effects on myocardial contractility by limiting Ca2+ entry and altering intracellular Ca2+ release. The aim of this study was to compare the direct cardiac effects of isoflurane, desflurane and new volatile anesthetics, sevoflurane, in combination with diltiazem on the isolated rat heart. METHODS: Sprague-Dawley rat hearts (N = 60) were isolated and perfused with oxygenated modified Krebs solution at 55 mmHg with 0.5, 1, 2 MAC of isoflurane, desflurane or sevoflurane in combination with diltiazem 42 ng/ml (group 1) and 84 ng/ml (group 2). Isovolumetric left ventricular pressure (LVP), rate of change ventricular pressure (dP/dt), heart rate and coronary flow were measured. To examine the indirect metabolic effect due to autoregulation of coronary flow, O2 delivery (DO2), myocardial O2 consumption (MVO2) and percent O2 extraction (POE) were also monitored. RESULTS: Diltiazem plus volatile anesthetics depressed LVP and dP/dt and increased coronary flow dose-dependently. They also decreased heart rate. In the group 2, at 2 MAC of inhaled anesthetics heart rate was significantly decreased than group 1. There were no statistical significance between isoflurane, desflurane and sevoflurane on myocardial contractility and myocardial oxygenation. CONCLUSIONS: These in vitro RESULTS demonstrate that clinical dose of diltiazem plus isoflurane, desflurane or sevoflurane has similar effects on myocardial contractility and coronary flow.

This study was carried out in order to examine the urinary excretion of electrolytes (Na, K) and their relationship with blood pressure, and to estimate the amount of daily salt intake in a rural community. From January to March in 1987, a mobile screening team visited 40 villages, and carried out health screening of 537 adult volunteers whose age were over 30 years and collected 12-hours overnight urine. To determine the completeness of collection, the urinary creatinine was measured. If the creatinine excretion was beyond the range given to the age group, the sample was excluded from the analysis as an imcomplete collection; 345 samples were remained for analysis. This study revealed the following results. 1. The mean excretion amounts of urinary electrolytes for 12 hours were Na 193.5 mEq, K 20.8 mEq, creatinine 1.0 g. The mean ratio of electrolytes were Na/K 9.84, Na/creatinine 0.44, K/creatinine 0.046. 2. Both the mean excretion amount of K and the mean ratio of K/creatinine were less in hypertensives than in normotensives. K excretion also showed a tendency towards a decrease in inverse proportion to systolic blood pressure when it exceeded 120 mmHg. There was no significant difference between the hypertensives and normotensives in Na excretion. The sodium to potassium ratio increased in proportion to systolic blood pressure. 3. The meand daily salt excretion amount was 22.4 g. Assuming that 90% of the intake was excreted, the estimated amount of daily salt intake was 24.9 g.
