Purpose: To analyze the outcome of radiation therapy for patients with a metastatic carcinoma of cervical lymph nodes from an unknown primary (MUO), and identify the prognostic factors for these patients. Materials and Methods: Between July 1981 and June 1999, 39 patients with MUO underwent radiation therapy with curative intent. Twelve patients were treated with radiation therapy alone (Group 1), 8 with neoadjuvant chemotherapy followed by radiation therapy (Group 2), and 19 with either an excision or neck dissection and postoperative radiation therapy (Group 3). There were 31 males and 8 females, with a median age of 55 years, ranging from 25 to 77 ears. The median duration of follow-up was 38 months, ranging from 3 to 249 months. Results: The 5-year overall survival rate was $55\%$. According to the treatment modality, the 5-year disease-free survival rates of Groups 1, 2 and 3 were 48, 19 and $75\%$, respectively (p=0.0324). In addition to the treatment modality, the appearance of the primary site was a significant prognostic factor for disease-free survival (p=0.0085). Conclusion: Surgical resection and radiation therapy achieves a superior disease-free survival compared to radiation therapy alone, either with or without chemotherapy Further investigation Is needed to evaluate the role of chemotherapy in the treatment of MUO.
Purpose : The purpose of this study was to compare the results of ACL reconstruction using bone-patellar tendon-bone to hamstring. Materials and Methods : Thirty-two ACL reconstructions with autogenous BPTB and eighteen reconstructions with hamstring were compared in terms of functional outcome, stability and tunnel expansion. Results : The functional score of BPTB group was higher than hamstring group in OAK(Orthopadishe Arbeitsguppe Knie) and IKDC(International Knee Documentation Committee) system. In BPTB group, OAK scores were 71.6$({\pm}10.0)$ preoperatively and 88.5$({\pm}7.9)$ finally. In hamstring group, OAK scores were 73.9$({\pm}11.5)$ and 82.5$({\pm}12.9)$ respectively. There was no difference in stability checked by either $KT-1000^{TM}$ or stress view. Anterior tibial translation measured by $KT-1000^{TM}$ were 2.4$({\pm}1.8)$mm in BPTB and 2.3$({\pm}2.4)$mm in hamstring group. Anterior tibial translation in stress view were 2.8$({\pm}3.4)$mm in BPTB and 2.8$({\pm}2.5)$mm in hamstring group. There was no difference in tibial tunnel expansion but femoral tunnel was more enlarged in hamstring group than BPTB (P=0.03). Conclusion : As there was no difference in stability between two groups, it seems prudent to select either graft defend on such factors as anterior knee pain, skeletal maturity and cosmetic concern. Tunnel expansion seems not to affect stability, but further study is needed to confirm that decrease of which might improve stability.
Purpose : To clinically analyze 62 patients who had meniscal repair and compare the results according to methods of repair. Materials and Methods : Between May 1997 and June 1998, we repaired 68 torn menisci in 68 patients. There were 52 male and 10 female with an average age of 26.9 years(ranging from 6 to 51 years). We used Linvatec suture in 46 knees(group A)and meniscal arrow in 16 knees(B group). In six knees we used Linvatec and meniscal arrow both. These 6 knees were excluded and 62 of 68 repaired meniscus were analyzed in this study. Average follow-up period was 18.5 months(ranging 12 to 26 months). We evaluated clinical results by Tapper and Hoover's grading system and subjective symptoms of the patients. Results : There were excellent in 47 cases$(76\%)$, good in 12$(19\%)$ and fair in 3$(5\%)$. In group A, there were excellent in 35 cases$(76\%)$, good in 9$(20\%)$ and fair in 2$(4\%)$. In group B, there were excellent in 12 cases$(75\%)$, good in 3$(19\%)$ and fair in 1$(6\%)$. There was no significant differences in clinical results between two groups. But mean operative time taken for meniscus repair was 40 minutes in group A and 25 minutes in group B. Conclusion : We can obtain good clinical results with short operation time in meniscal repair by proper selection of methods of repair according to the type, location, and size of meniscal tear and associated lesions.
Purpose: To compare of the results between anterior cruciate ligament (ACL) reconstruction alone and combined with high tibial osteotomy for ACL ruptured knees with varus alignment. Materials and Methods: We retrospectively reviewed 8 cases of ACL reconstruction combined with high tibial osteotomy (Group I) and 13 cases of ACL reconstruction alone (Group II) for varus angulated ACL ruptured knees (from March 2005 to February 2007). Mean age were 34.1 years (range: 20-53) in Group I, 34.9 years (range: 21-50) in Group II. Average follow up period were 22.6 months (range: 12-35) in Group I, 20 months (range: 13-33) in Group II. We analyzed clinical and radiological results. Results: There were no significant differences in clinical and radiologic results between two groups for IKDC scores, Lysholm knee scores, Lachman test, pivot shift test, KT-2000 arthrometer, $30^{\circ}$ and $90^{\circ}$ anterior drawer stress radiographs. Tegner activity scales and Cincinnati knee ligament rating scales were 4.9, 57.9 in Group I, and 5.6, 72.9 in Group II. Group I was statistically lower than Group II for Tegner activity scales and Cincinnati knee ligament rating scales (p<0.05). Conclusion: There were no significant differences in daily living between ACL reconstruction alone and combined with high tibial ostetomy for varus angulated ACL ruptured knees. However, ACL reconstruction combined with high tibial osteotomy could limit sport activity ability.
This study was carried out to observe the change in uterine cyclic nucleotide level and the effect of PAF on cyclic nucleotides in uterine tissue in early pregnany in order to understand reciprocal relation ship between PAF and cyclic nucleotides in pregnancy in the rat. The test groups were injected intramuscularly with $1{\mu}g$ of PAF or 1.25mg of BN-52021 on day 0, 1, 2, 3, 4 and 5 of pregnancy. The level of cyclic nucleotide in removed uterine tissue was assayed by using cyclic nucleotides test kits. The results showed that the cyclic AMP content in uterine tissue of non-pregnant at pro-oestrus rat was $2.91{\pm}0.33$ pmol/mg protein which was lower than those of pregnant rat. The cyclic GMP content in uterine tissue of non-pregnant rat was $0.39{\pm}0.20$ pmol/mg pro-tein which was also lower than those of pregnant rats. The maximum level in cAMP was $5.92{\pm}1.72$ pmol/mg protein on day 3 and cGMP, $1.03{\pm}0.22$ pmol/mg protein on day 4. On each day of pregnancy, PAF induced the increased cAMP level ompared with that of intact rat. That was significant on day 0, 2 and 4 of pregnancy, p<0.05, on the other hand PAF receptor antagonist, BN-52021 ecreased cAMP level in uterine tisssue. PAF as well as BN-52021 had not an consistent effect on changes in cGMP level. These results suggest that cyclic nucleotide levels in uterine tissue ware increased during early pregnancy and PAF influences cAMP level in uterine rather than cGMP level during peri-implantation period, accordingly demonstrating a possible involvement of PAF in the regulation of implantation-related events through cAMP-mediated process.
This experiment was carried out to obtain some imformations about the ecological variations of the heading time of the newly breeded Indica x Japonica varieties/pedigrees according to the seasonal changes of the seeding date. day length and temperature. The results obtained are summarized as follows; 1) At all varieties. days to heading showed a straight reduction according as the seeding time was delayed. 2) At the group of Japonica varieties. the days to heading of early maturing varieties were much shortened and that of medium or late maturing varieties were little or not shortened under high temperature condition but at the group of Indica ${\times}$ Japonica va rieties/pedigrees. days to heading were significantly elongated under high temerature condition. 3) At the group of Japonica varieties. the effect of the short day condition on the days to heading was significantly high at the medium and the late maturing varieties than at the early maturing varieties. however. the short day effect on the reduction of days to heading was not related with the earlyness of each varieties at the group of Indica ${\times}$ Japonica varieties/pedigrees. 4) Days to heading of all varieties under the high temperature condition were longer than that under the ordinary culture. On the other hand, the days to heading of Japonica varieties under the short day treatment were shorter than the days to heading of ordinary culture but at the group of Indica x Japonica varieties/pedigrees. the days to heading under the short day treatment were longer than ordinary culture. 5) At both varieties groups. the days to heading at each seeding time were significantly correlated with days to heading at ordinary cultivation. fl) At the group of Japonica varieties. relatively high correlation(p=0.1) was recognized between the days to heading by delay of seeding time, but at the group of Indica ${\times}$ Japonicava rieties/pedigrees, correlation between the ordinary heading date and the shortening rate of days to heading was very low.

Two feeding trials were carried out to investigate apparent nutrient digestibility of flounder fed experimental diets containing different levels of macro-nutrients by satiation feeding rate (Exp-1) and feeding frequency (Exp-2). Triplicate groups of fish averaging 280 g were fed three experimental diets which contained different levels of carbohydrate, protein and lipid by two feeding regimes (satiation and 80% satiation) and four feeding frequencies (three meals a day, two meals a day, one meal a day and one meal every two days). Feces were collected using a fecal collection column attached to fish rearing tanks for 6 weeks. Apparent digestibilities of dry matter, protein, lipid, energy and carbohydrate were not affected by feeding satiation rate in Exp-1. Apparent protein digestibility was not affected by feeding frequency, whereas affected by dietary composition in Exp-2. Apparent protein digestibility of fish fed a high-protein diet showed a tendency to become higher compared to that of fish fed high-carbohydrate diet and high-lipid diet at the same feeding frequency. Apparent lipid digestibility was not affected by dietary composition, however, affected by feeding frequency. Apparent digestibilities of energy and carbohydrate were affected by both dietary composition and feeding frequency. Apparent digestibities of energy and carbohydrate in fish fed the high-protein diet showed a tendency to become higher compared to that of fish fed the high-carbohydrate diet and high-lipid diet at the same feeding frequency. Apparent digestibities of energy and carbohydrate tended to decrease with increasing of feeding frequency at the same dietary composition.

Background : Unexplained weight loss, which commonly occurs in patients with chronic obstructive pulmonary disease(COPD), is important because weight loss is an independent risk factor of mortality and morbidity in these patients. Leptin is known to play an important role in regulating body weight. In addition, the tumor necrosis factor($TNF-{\alpha}$) might also play a potential role in the weight loss experienced in chronic wasting disease. The aim of this study was to determine the influence of plasma leptin and the circulating $TNF-{\alpha}$ system to the difference in the body compositions in patients with COPD. Methods : Spirometry, body composition analysis and the plasma concentrations of leptin, $TNF-{\alpha}$ and a soluble TNF receptor (STNF-R55, -R75) were measured in 31 patients with chronic bronchitis and 10 patients with emphysema. The COPD subtype was classified by the transfer coefficient of carbon monoxide, DLco/VA. Results : The circulating levels of leptin were significantly lower in those patients with emphysema($108.5{\pm}39.37pg/ml$) than those with chronic bronchitis($180.9{\pm}57.7pg/ml$). The circulating levels of sTNF-R55 were significantly higher in the emphysema patients($920.4{\pm}116.4pg/ml$) than in those with chronic bronchitis($803.2{\pm}80.8pg/ml$). There was no relationship between the circulating leptin levels and the activated TNF system in patients with chronic bronchitis and emphysema. However, the circulating leptin levels correlated well with the BMI and fat mass in both patient groups. Conclusion : These results suggest that the weight loss noted in emphysema patients may be associated with the activation of the $TNF-{\alpha}$ system rather than the plasma leptin level.

Purpose: We reported our preliminary result in 2001. At that time, the follow-up period was too short to evaluate the survival benefit of adjuvant chemotherapy in gastric cancer without serosal invasion. Therefore, we followed those patients for 66 months to determine the long-term effects of adjuvant chemotherapy. Materials and Methods: We analyzed the recurrence pattern, the survival rate, and the disease-specific survival of 135 patients by reviewing their medical records and calling the patients or their relatives. All enrolled patients were included in the intention-to-treat analysis of efficacy. Results: The follow-up rate was $89.6\%$ (121/135), and the median follow-up duration was 66 months. Among the 135 patients, 4 relapsed in group 1 (5-FU+cisplatin), 7 in group 2 (mitomycin C+oral 5-FU), and 6 in group 3 (oral 5-FU only). The overall survival rate was $89\%$ in group 1, $84\%$ in group 2, and $82\%$ in group 3. There were no differences in the overall survival rates and the disease-specific survival rates among the three groups. Conclusion: Oral chemotherapeutic agents have an acceptable effect for adjuvant chemotherapy compared with intravenous agent. However, a large-scale, prospective, randomized study, including a control group, is needed for an exact evaluation.

Plantain has been used for antidiarrhea, antihemorrhage and the remedy of indigestion. Plantain was extracted with ethanol and fractionated systemically with n-hexane, chloroform, ethylacetate (EtOAC) and n-butanol. Antioxidant index (AI was expressed as induction period of oil containing various fractions/induction period of oil of 600 ppm) of EtOAC fraction was the highest among fractions in vitro. The protective effects of the EtOAC fraction of plantain (PE) administered 1 mL orally or intraduodenally on experimentally induced gastritis, gastric ulcer and gastric secretion were evaluated in rats. Sprague-Dawley rats weighing 250∼300 g were divided into 4 groups; negative control group (CON), PE 200 mg/kg treated group (PEL), PE 400 mg/kg treated group (PEH) and positive control group (cimetidine 100 mg/kg-CMT or omeprazol 100 mg/kg treated group-OMT), respectively, PE significantly suppressed HCl-ethanol induced gastric lesions and indomethacin-induced gastric ulcers (administered subcutaneouly) in rats. Specially PE 400 mg/kg showed significantly inhibitory effect, which was more potent than that of 100 mg/kg of commercial drug, cimetidine, and elevated an inhibitory effect to be close to the level in inhibitory ratio of omeprazol administered group in Shay's ucler. On gastric secretion in pylorus ligated rat, PE 200 mg/kg and 400 mg/kg decreased the gastric volume and acid output, but did not show an apparent effect on pepsin activity. In addition, PE 400 mg/kg depressed gastric ulcers induced by water immersion stress and duodenal ulcers induced by cysteamine administered subcutaneouly. These results suggest that the ethylacetate fraction of plantain can be used in prevention and treatment of experimentally induced gastric mucosal damage and ulcers.
