Idiopathic orbital myositis, a subgroup of inflammatory orbital pseudotumor may occur with acute-onset periorbital pain, diplopia, and, in most cases, eyelid swelling. Proptosis, extraocular muscle motility restrictions, and response to oral prednisolone administration were characteristic. Although the CT appearance of orbital myositis is often helpful, the findings are not pathognomonic: correlation with history, clinical finding, and therapeutic response must be considered in making the diagnosis. The results of corticosteroid therapy on the orbital pseudotumor caused by orbital myositis were as follows: 1. The effect of corticosteroid was more effective in single extraocular muscle involvement than in that of a multiple extraocular muscle. 2. Early age of onset and early treatment after symptom increased the effectiveness of corticosteroid therapy.

Atrial natriuretic peptide(ANP) is a 28-amino acid hormone with potent natriuretic effect and diuretic one. ANP wag originally thought to be involved in the regulation of blood pressure and blood volume. However, recent studies have indicated that ANP has much wider physiologic roles, such as the regulation of mitoses, the secretion of thyroglobulin, the production of cerebrospinal fluid and aqueous fluid formation. This peptide hag been detected in the anterior uvea, retina and corneal endothelium. It was reported that ANP decreased intraocular pressure and aqueous humor formation. However the distribution of ANP in the eye was not clearly confirmed. This study was carried out to localize the immunoreactive ANP in the rat eye. The distribution of alpha-ANP in the rat eye was studied by immunohistochemistry using a polychnal antibody against synthetic rat alpha-ANP. Immunoreactive ANP was localized intensely in the epithelium of the ciliary body. ANP immunoreactivity was also strong in the corneal endothelium, iris and in the anterior epithelium of the lens. The immunoreactivity was observed in the nerve fiber layer, ganglion cell layer and inner plexiform layer in the retina. These data clearly confirm that ANP is widerly distributed and that it takes part in diverse functions in the rat eye.

INTRODUCTION: It is now generally accepted that free radicals play an important role in the development of various forms of tissue damage and pathological events, such as heart disease, cancer, and aging. On the other hand, it is difficult to demonstrate the injurious actions of free radicals in vivo, and it has not been clearly proven experimentally whether the damage is really caused by free radicals, nor how the free radicals damage biological molecules, primarily because of the difficulty in generating free radicals in biological systems under controlled conditions. PURPOSES OF STUDY: In this study, we investigated whether the histologically different part of lesion is created in liver injuries by free radicals formed from each mechanism. we investigated the usefulness of the ICG excretion test as an early indicator of liver injury, and the significance of an increase of urinary biopterin in free radical injury. MATERIALS & METHODS: In this study, the acute hepatic injuries were induced in the Sprague-Dawley rat by intraperitoneal injection with CCl4(0.125 ml/100 gm body wt.) and AAPH(1 mg/100 gm body wt.). Control rats were treated with 0.5 ml of corn oil per 100 gm via intraperitoneal route. And then, liver function tests(ALT, AST, ALP, gamma-GTP, serum bilirubin and ICG excretion test), alpha-fetoprotein, urinary biopterin and histologic changes were serially examined. Total 130 rats were prepared, and each group of 5 rats of them were sampled at intervals of 2, 4, 8, 12, 24, 48 hours following administration of CCl4, AAPH solution. All values were expressed as mean +/- standard error. The results of all treatment groups and control group were analyzed by ANOVA with Duncan's multiple range test for variable. And then, the correlations between the increasing rates of urinary biopterins, ICG T1/2 and those of classic liver enzyme activities, serum bilirubin levels were analyzed for statistical significance by Pearson correlation analysis. In this analysis, a p-value below 0.05 was considered to be statistically significant. RESULTS: 1. Activities of liver enzymes(serum AST, ALT, ALP and gamma-GTP) and levels of serum bilirubin significantly increased in all the treatment groups compared to control. As time passed, these levels continued to increase(p<0.05). 2. In comparison with AAPH treatment group, serum AST and ALT of CCl4 treatment group increased more significantly(p<0.05). 3. In ICG excretion test, ICG T1/2 of all the treatment groups were greatly prolonged from about 4 - 12 hours. Compared to AAPH treatment group, ICG T1/2 of CCl4 treatment group was more significantly prolonged(p<0.05). 4. As time passed, urinary biopterin levels of all the treatment groups increased from about 24 hours. Urinary biopterin levels of AAPH treatment group increased more significantly than in CCl4 treatment group from about 48 hours(p<0.05). 5. In histopathologic view, CCl4 treated hepatic acini showed that hepatocytes in centrilobular zone were degenerated. But, AAPH treated livers showed that all hepatocytes were degenerated. 6. Passive hemagglutination tests of alpha-fetoprotein showed negative reaction in all the treatment groups and control group. 7. Correlations were statistically significant(p<0.05) between the increasing rates of urinary biopterin levels and those of classic liver enzyme activities(except, serum AST), and serum bilirubin levels in CCl4 induced hepatotoxicity. 8. In AAPH induced hepatotoxicity, the increasing rates of urinary biopterin levels correlated with those of classic liver enzyme activities(serum ALT, AST, ALP, -GTP) and serum bilirubin levels(p < 0.05). 9. The increasing rates of ICG T1/2 correlated significantly with those of liver enzyme activities and serum bilirubin in CCl4 and AAPH induced hepatotoxicity(p<0.05), but there were no statistically significant correlations between the increasing rates of ICG T1/2 and those of serum ALT in CCl4 induced hepatotoxicity. 10. And also, the increasing rates of ICG T1/2 correlated significantly with those of urinary biopterin in CCl4 and AAPH induced hepatotoxicity(p<0.05). CONCLUSION: We observed in this study that the difference in hepatic lesions induced by free radicals might be closely related to the site where free radicals had been generated. We indirectly found that the tissue damage is caused by free radicals. There were excellent correlations between urinary biopterin levels, ICG excretion test and classic liver enzyme activities, and serum bilirubin levels in acute hepatic injuries induced by free radicals from CCl4 and AAPH. Also, we determined that ICG excretion test is a saturable process for evaluation of acute hepatic injury. The urinary biopterin levels in CCl4 treated groups were significantly different from those of AAPH treated groups suggesting that an unknown mechanism is concerned with free radical induced biopterin elevation. However, the level of urinary biopterin in free radical injury may be a useful complementary index.

Using immunohistochemical technique, we observed time-sequentially to T and B lymphocyte in the ciliary body of the endotoxin induced uveitis in rat. The primary antibodies for immunohistochemical stain of the lymphocyte were IgM heavy chain, IgG heavy chain, T suppressor/cytotoxic (CD8) and T helper/macrophage (CD4) was performed in the frozen section. The intensity of immunohistochemical reaction for surface IgM positive cells increased from 12hours and reached most strong intensities at 24hours after endotoxin injection and then decreased rapidly, but the intensity for surface IgG positive cells increased from 48hours and sustained 96hours. There were no significant changes of intensity of immunohistochemical reaction for T cells except slightly increased T suppressor/cytotoxic cells (CD8).

PURPOSE: Heptaplatin (SKI-2053 R) is a new platinum analogue, with a better toxicity profile than cisplatin, and has antitumor activity even in cisplatin resistant cell lines. 5-fluoruracil (5-FU) has shown synergy with platinum compounds. This phase II trial was designed to determine the efficacy and toxicities of heptaplatin/ 5-FU (5-fluorouracil) for treating stomach cancer. MATERIALS AND METHODS: Thirty-two patients with advanced, measurable gastric adenocarcinomas were enrolled in this trial. The treatment consisted of heptaplatin, 400 mg/m2/day (1 hour IV infusion), on day 1 and 5-FU, 800 mg/m2/day (12 hours IV infusion), on days 1 to 5. The cycles were repeated every 3 weeks. RESULTS: Of the 26 evaluable patients, 9 had partial responses and 1a complete response (overall response rate, 38%; 95% confidence interval, 19~57%). The median response duration was 23 weeks (range: 4~60 weeks). The median time to progression was 26 weeks (range: 3~68 weeks). The grades III-IV toxicities were mostly hematological toxicities: leucopenia was observed in 11 patients (35%) and thrombocytopenia 4 (13%). No definite neuropathy was observed. Grade I-II nephropathy was also noted: grade I high BUN/creatinine levels occurred in 5 patients (16%), grade II proteinuria 2 (6%), grade I proteinuria 5 (16%). Neutropenic fever developed in 5 patients (16%) and 1 died of pneumonia in a neutropenic state. CONCLUSION: This study suggests that the regimen of Heptaplatin/5-FU should be effective and have a favorable toxicity profile for the patients suffering with advanced stomach cancer.

Nandrolone decanoate(ND), one of the anabolic steroids, has been used by athletes to build muscle mass and enhance weight-lifting performance and has also shown to be useful in malnourished ESRD patients. However, ND has several adverse effects including edema. After we experienced a case of severe edema and transient ultrafiltration failure(TUF) requiring more frequent number of dialysis during ND treatment, we prospectively studied the incidence and clinical characteristics of TUF during ND treatment. Among 30 ND-treated patients, 7 patients developed TUF. All TUF+ patients were female and had sigificantly higher number of patients with congestive heart failure, more use of minoxidil and moderate to severe malnutrition than TUF- patients. There were no significant differences in age, duration of dialysis, and number of diabetics between TUF+ and TUF- group. In ND-treated male patients, the number of patients with CHF and moderate to severe malnutrition and with use of minoxidil were significantly lower than TUF+ ones. Body weight and serum albumin concentrations were significantly increased 2-3 months after ND treatment in TUF+ patients. But there were no differences in body weight and serum albumin in TUF-patients. In TUF+ patients, frequency of HD increased from 3 times to 4 to 6 times a week. CAPD patients with TUF+ had more frequently used 4.25% dialysate and number of exchanges were increased. In most TUF+ patients, severe edema and TUF were disappeared about 2 weeks after treatment. Most TUF+ patients returned to previous schedle of dialysis. In conclusion, ND seems to induce TUF in ESRD patients who had risk for volume regulation such as CHF, hypoalbuminemia, or the use of minoxidil.

Peritonitis is one of the major complication of continuous ambulatory peritoneal dialysis (CAPD) and the most common cause of hospital admission and for termination of peritoneal dialysis. We retrospectively analyzed the incidences and causative organisms of CAPD peritonitis according to season/month of the year under the hypothesis that climate factors, increased temperature and humidity, may changes the incidences and causative organisms of peritonitis. There were a few studies about this issue and in most cases the result was inconclusive because of the limitation in the limited range of climate factors such as temperature and humidity. Wide annual differences of temperature (-3.4-25.4 degrees C) and humidity (61-81%) may affect the rate of peritonitis episode in the area where the current study was performed. Data from 80 patients(49 male, 31 female), with a mean age 48.3+/-14.5 years and mean CAPD period 14.0+/-9.0 months, followed from September 1996 to July 1999, were reviewed. Fifty-three cases of peritonitis were found in 1,123 patient-months, a rate of 0.56 episode/patients- year, and 0.047 episode/patient-month. The months in which the incidence of peritonitis above average was March (5.05%), May(7.96%), July (10.8%), August (6.25%), September (6.06%). The incidence of peritonitis was the lowest in November (1.31%). The incidence in hot season (May-September : average temperature for three years 21.9degrees C, humidity 74%) was 0.065 episodes/patient-month, which was significantly higher than in cold season (October-February : 5.9degrees C, 64.4%)(p<0.05). Average temperature for three years in the study area was 13.2degrees C with maximal temperature of 25.4degrees C (August) and minimal of -3.4 degrees C (January). Average humidity for three years in the study area was 68.4% with maximal humidity of 81% (July) and minimal of 61% (April). The incidence of peritonitis paralleled with temperature and humidity, highest in July (0.080/pt-month) and lowest in November (0.013/pt-month) and were directly correlated with temperature (r=0.53, p<0.05) and humidity (r=0.59, p<0.05). Among 53 episodes of peritonitis, gram positive peritonitis, gram negative peritonitis and culture negative peritonitis were 36.9%, 15.0% and 45.2%, respectively. From March to August, gram positive peritonitis was 50% and culture negative peritonitis was 42.4%. From September to February, culture-negative peritonitis was 52.9% and gram negative peritonitis organisms was 29.4%. In contrast to gram positive organisms which showed increased in hot weather, gram negative organisms showed uniform distribution throughout the year. There were no significant monthly differences in peritoneal fluid WBC count on admission and negative conversion period of that. Our data suggest that high temperature and humidity can adversely affect the incidence of CAPD peritonitis and may change the distribution of causative organisms.

Studies describing the effects on blood pressure control by hemodialysis(HD) or continuous amulatory peritoneal dialysis(CAPD) have yielded conflicting results with respect to 24 hour blood pressure control, diurnal variation and blood pressure loads. The aim of the study was to investigate the effect of beginning with HD or CAPD on blood pressure control, diurnal variation and blood pressure loads using ambulatory blood pressure monitoring(ABPM). Twen-ty-seven end-stage renal disease(ESRD) patients(12 on HD and 15 on CAPD) were enrolled into the study. Patients with cardiovascular diseases, erythro-poietin therapy, or severe edema were excluded. ABPM were performed two times before and after the initiation of dialysis. Mean duration of interval between pre- and post-dialysis ABPM were 17+/-4 days on HD and 13+/-3 days on CAPD. Daytime and nighttime were defined as the time from 6:00 AM to 10:00 PM and from 10:00 PM to 6:00 AM of the next day. Systolic and diastolic loads were defined as the percentage of the incidence of systolic and diastolic blood pressure over l% and 90mmHg. Dipper meaning the presence of normal diurnal difference were defined as the differences of daytime- nighttime mean arterial pressure more than 5mmHg. In HD patients, mean systolic and diastolic blood pressure and mean arterial pressure were significantly decreased after dialysis during 24 hour, day- time and nighttime. In CAPD patients, those were also significantly decreased after dialysis during 24 hour, daytime and nighttime(p<0.05). Diurnal differences were increased after CAPD(3.3+/-9.4 vs 5.4+/-6.8mmHg) but decreased after HD(4.3+/-6.2 vs 2.4+/-10.8mmHg) and the differences of diurnal difference between two groups were significantly different(+2.1+/-9.0 vs 1.9+/-8.4mmHg, p<0.05). Proportions of dipper among patients were increased from 16.7 to 66.7% in HD and from 33.3% to 60% in CAPD without statistical significance between two groups. Systolic and diastolic loads were significantly decreased after HD(from 75.0+/-38.0 to 37.5+/-43.8%, from 45.2+/-29.7 to 12.5+/-12.8%, respectively, p<0.05) and after CAPD(from 63.1+/-30,1 to 32.3+/-27.1%, from 43.4+/-36.2% to 12.2+/-16.9%, respectively, p<0.05). Systolic and diastolic loads of daytime and nighttime were significantly decreased after each dialysis modality except nighttime diastolic pressure load in HD. In conclusions, both HD and CAPD improve BP control in ESRD patients. CAPD has more benefit to control of diurnal variations in ESRD patients.
