ABSTRACT This study was conducted to determine influence of planting date, seeding rate and phosphate rate on main growth, characters, yield and chemical composition of senna from March 11, 1998 to December in Cheju Province. Days to flowering was lessened as planting date was delayed. The plant height of senna was the longest at 31 March planting (99cm) than at the other planting date. Stem diameter, number of leaves were increased at 31 March but number of branches was not affected by planting date. And number of withering leaves were increased as planting date was earlier. Fresh forage yield per lOa, for senna was the greatest (4,660kg) at 31 March planting, the second was 4,397kg at 1 April planting and the reduced the 3,473kg at 11 March planting. Also dry matter yield per lOa, crude protein yield and total digestable nutrient (TDN) yield was nearly the same tendency. Crude protein, crude fat percent was the greastest at 11 March planting and than decreased with further increased at planting date. Crude ash and crude fiber percent was decreased tendency as planting date was delayed. Nitrogen free extract (NFE), TDN percent was increased tendency as planting date was delayed. SPAD reading value of leaves had an efficiency increased as planting date was delayed.

Background Human endogenous retroviruses (HERVs) constitute around 8% of the human genome and have important roles in human health and disease, including cancers. Previous studies showed that HERV envelope (Env) proteins are highly expressed in cancer tissues and co-related with cancer progression. KAP1 has been reported to play a key role in regulating retrotransposons, including HERV-K, through epigenetic silencing. Objective The relationship between KAP-1 and HERV Envs expressions was analyzed only in tumor cell lines and has not yet been studied in cancer tissues. In this study, we analyzed the expression patterns and relationship between KAP1 and HERV Env proteins in ovarian cancer tissues. Method The expression patterns of KAP-1 and HERV Env proteins, including HERV-K and HERV-R, were analyzed in ovarian cancer tissue microarrays that contained 80 surgical specimens, including normal ovary and malignant ovarian cancers. Results The expression of HERV-R Env and KAP1 proteins is signifcantly higher in ovarian cancer compared with normal ovary tissues. However, the expression of HERV-K Env did not change signifcantly in cancer tissues. The expression patterns of HERV-K Env and HERV-R Env signifcantly increased in early stages of cancer and KAP1 expression was higher in certain stage and types of cancers. However, the expression of HERV-K Env, HERV-R Env, and KAP1 did not change in diferent age groups. The correlation between the expression of KAP1 and HERV-Env, including HERV-K and HERV-R, was not signifcantly correlated. Conclusions The results of this study showed that there was no signifcant correlation between the expression of KAP1 and HERV Env proteins in ovarian cancer tissues, unlike studies with cell lines in vitro. These results suggest that the actual expression of HERV Env proteins in ovarian cancer tissues may be regulated through various complex factors as well as KAP1.

The objective of this study was to investigate the managing realities of EVD and provide a descriptive survey with the attempt to obtain basic data needed for the standardization of EVD management. For that purpose, 220 questionnaire copies were distributed to those nurses who were working with intensive care units at university hospitals, general hospitals, semi-general hospitals in Seoul, Kyongki-de and local areas. Of 158 returned questionnaire copies, 139 were used for analysis. Data were collected during the term of academic seminars of Neurosurgery Nursing Committee and KICA (Korea Intensive Care Association), ranging from Oct. 26 through 27. 2000. The tools utilized a structured questionnaire form consisting of 21 questions on general characteristics, the level of understanding, the level of work performance, standard management guidelines, etc. The data collected were analysed with frequency, percentage, mean vague, chi -square test using the SPSS 10.0 program Findings were revealed, as follows: For managing the prevention of EVD infection, aseptic technique was found to be of the most importance (48.9%),'the technique should be carried out at an operation room'(92.8%), but it was actually performed at intensive care units (over 51.5%). 'The term of antibiotics use should be less than 7 days' (81.8%), while it was actually executed for less than 7 days (49.5%). 'The proper time of quittance from it should be within less than 7 days'(74.1%) but actual quittance was executed only by 51.1%. 'Set exchange is needed' by 54.0% but actual exchange was implemented merely by 28.1%. 'The subject of management should be nurses' was reflected by 40% but actually 52.0% were carried out. As a result of hating analysed the understanding of the management of EVD by general characteristics, a significant difference was found in the necessity for set exchange by hospitals, in the time of quittance of a catheter, and in ablution items by work experience. The result of hating analysed the work performance levels of EVD management by general characteristics revealed that a significant difference in administration facilities of medicine by the classification of hospitals, especially the use of antibiotics and the quitting time of a catheter by the classification of intensive care units, and in the use of antibiotics and ablution items by the standard management guidelines.

Purpose: We investigated the clinical outcomes of deceased donor kidney transplantation (KT) using kidneys with terminal acute kidney injury (AKI). Methods: Between February 2000 and December 2013, we performed 202 deceased donor renal transplants from 159 brain dead donors. According to the expanded criteria donor (ECD) and AKI network criteria, we divided 202 recipients into 4 groups: Group I: Non-AKI & standard criteria donor (SCD) (n = 97); group II: Non-AKI & ECD (n = 15); group III: AKI & SCD (n = 52); and group IV: AKI & ECD (n = 38). Results: The incidence of delayed graft function (DFG) was significantly higher in patients with AKI than it was in the non-AKI group (P = 0.008). There were no significant differences among the 4 groups in graft survival (P = 0.074) or patient survival (P = 0.090). However, the long-term allograft survival rate was significantly lower in group IV than it was in other groups (P = 0.024). Conclusion: Allografts from deceased donors with terminal AKI had a higher incidence of DGF than did those from donors without AKI. However, there is no significant difference in graft and patient survival rates among the groups. So, the utilization of renal grafts from ECDs with terminal AKI is a feasible approach to address the critical organ shortage.

<P><B>Abstract</B></P> <P>In order to overcome the limitations of single <I>in vitro</I> eye irritation tests, Integrated Approaches to Testing Assessment strategies have been suggested for evaluating eye irritation. This study developed two tiered approaches combining alternative test methods. They were designed in consideration of the solubility property of test chemicals and to use the RhCE tests at final steps. The tiered approach A is composed of the STE, BCOP, HET-CAM or RhCE tests, whereas the tiered approach B is designed to perform simultaneously two <I>in vitro</I> test methods at the first stage and the RhCE test at the final stage. The predictive capacity of the two tiered approaches was estimated using 47 chemicals. The accuracy, sensitivity, and specificity value of the tiered approach A were 95.7% (45/47), 100% (34/34), and 84.6% (11/13), respectively, whereas those of the tiered approach B were 95.7% (45/47), 97.1% (33/34), and 92.3% (12/13), respectively. The approach A and B were considered to be available methods for distinguishing test chemicals of Category 1 (all 73.3%) and No Category (84.6% and 92.3%), respectively. Especially, the approach B was considered as an efficient method as the Bottom-Up approach, because it predicted correctly test chemicals classified as No Category.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The proposed A and B approaches seem to be efficient strategies for evaluating eye irritation potency as they had higher predictive capacity than that of stand-alone <I>in vitro</I> test method. </LI> <LI> The B approach is considered to be an useful method for Bottom-Up approach in eye irritation IATA. </LI> </UL> </P>

Purpose To determine the incidence of atypical ductal hyperplasia (ADH) in needle biopsy and the upgrade rate to carcinoma, and to evaluate difference in findings between the upgrade and non-upgrade groups. Materials and Methods Among 9660 needle biopsies performed over 48 months, we reviewed the radiologic and histopathologic findings of ADH and compared the differences in imaging findings (mammography and breast US) and biopsy methods between the upgrade and non-upgrade groups. Results The incidence of ADH was 1.7% (169/9660). Of 112 resected cases and 30 cases followed- up for over 2 years, 35 were upgraded to carcinoma (24.6%, 35/142). The upgrade rates were significantly different according to biopsy methods: US-guided core needle biopsy (USCNB) (40.7%, 22/54) vs. stereotactic-vacuum-assisted biopsy (S-VAB) (16.0%, 12/75) vs. USguided VAB (US-VAB) (7.7%, 1/13) (p = 0.002). Multivariable analysis showed that only US-CNB (odds ratio = 5.19, 95% confidence interval: 2.16–13.95, p < 0.001) was an independent predictor for pathologic upgrade. There was no upgrade when a sonographic mass was biopsied by US-VAB (n = 7) Conclusion The incidence of ADH was relatively low (1.7%) and the upgrade rate was 24.6%. Surgical excision should be considered because of the considerable upgrade rate, except in the case of US-VAB.
