Dermal wound healing is a complex process that involved inflammation leading to re-epithelialization, granulation tissue, and tissue remodeling. Previous studies from our laboratory have shown that polysaccharides isolated from fungus, Phellinus gilvus (PG) have various anti-inflammatory activities. In present study, we have assessed the effect of polysaccharides from PG on the dermal wound healing of polysaccharides from PG in streptozotocin-induced diabetic rat model. Six of 6-mm circular wounds were created with biopsy punch on the 4th day after induction of diabetes. After 24 hours, each test substance was applied to the wound twice a day for next 5 days. Circular wounds treated with PG showed significantly reduced wound contraction and complete reepithelialization, as compared to wounds of non-treated (p < 0.05). These results show that polysaccharides isolated from PG enhanced wound repair in diabetic impaired healing, and could be developed as a wound healing agent in such clinical settings.

2.Influence of Awareness and Perceived Ease in Using Parental Leave on Job Satisfaction of Nurses in a Public Hospital
Journal of Korean Academy of Nursing Administration 2018;24(3):211-220
PURPOSE: The aim of this study was to identify whether awareness and perceived ease in using parental leave influence job satisfaction of nurses in a public hospital. METHODS: The participants were 425 nurses working in a public hospital. A questionnaire was used to collect data from October 12 to October 25, 2016. The influence of the factors on job satisfaction of nurses was analyzed by multiple hierarchical regression. RESULTS: Nurses taking leave accounted for 46.8% (75 nurses) of 160 married nurses. They worried about adaptation after return to work (30.7%) and complained about disadvantages related to using parental leave (45.3%). The percentage of nurses on leave replaced by new full time nurses was 70.7%. Nurses' awareness (β=.16) of perceived ease of using parental leave (β=.32) influenced the nurses' job satisfaction (R2=.21). CONCLUSION: To improve job satisfaction for nurses, it is necessary to increase awareness and perceived ease of using parental leave. Public hospitals should replace nurses on leave with temporary nurses and help returning nurses adapt to their jobs as they return to work. Nursing managers should create a healthy climate in which it is easy for nurses to take parental leave.

OBJECTIVE: This study was carried out to evaluate the effect of the isolation methods of inner cell mass from mouse blastocyst, types of feeder cells and treatment time of mitomycin C on the formation rate of ICM colony. METHODS: The inner cells were isolated by conventional immunosurgery, partial trophoblast dissection with syringe needles and whole blastocyst co-culture method. Commercially available STO and primary cultured mouse embryonic fibroblast (pMEF) feeder cells were used, and mitomycin C was treated for 1, 2 or 3 hours, respectively. The formation rate of ICM colony was observed after isolation of ICM and culture of ICM on the feeder cells for 7 days. RESULT: The ICM colony formation rate on STO were significantly higher in partial trophoblast dissection group (58%) than that in immunosurgery (12%) or whole blastocyst culture (16%) group (p<0.05). The formation rate on pMEF feeder layer was higher in partial trophoblast dissection (88%) and whole blastocyst culture (82%) group than that in immunosurgery (16%) group (p<0.05). When mitomycin C treated to pMEF for 2 hours, the formation rate of 88% was significantly higher than those of other conditions. CONCLUSIONS: Above results showed that the efficient isolation method of ICM from blastocyst was the partial trophoblast dissection and the appropriate treatment time of mitomycin C was 2 hours. However, the subculture of ICM colony and characterization of stem cells should be carried out to confirm the efficacy of the partial trophoblast dissection method.

OBJECTIVE: Telomerase is a ribonucleoprotein that synthesizes TTAGGG repeats onto chromosome ends. The expression of telomerase is thought to be required for cellular immortality and carcinogenesis. This study was conducted to examine the telomerase activation occurs in cervical carcinogenesis. METHODS: The standard telomeric repeat amplification protocol(TRAP) was used to examine telomerase activity in tissues of 10 normal cervix, 10 carcinoma in situ, and 21 invasive cervical carcinoma. RESULTS: Telomerase activity was detected in tissues of 16/21(76.2%) invasive carcinoma, in 5/10(50.0%) carcinoma in situ, and in 3/10(30.0%) normal cervix. But the degree of telomerase activity in normal cervix was weak. There was significant difference in 3 groups(p<0.05). The results of neoadjuvant chemotherapy in 10 invasive cervical carcinoma were as follows. In 8 cases of which tumor size decreased more than 50%, 5 were positive for telomerase. In 2 cases that didn't respond to chemotherapy by tumor size, 1 was positive for telomerase. There was no significant difference between 2 groups. All of the 5 cases that had pelvic lymph node metastasis revealed positive telomerase activity, and the 11 cases of 16 cases that didn't have pelvic lymph node metastasis were positive for telomerase, but there was no significant difference in 2 groups. The positivity of telomerase activity in clinical stage of invasive cervical carcinoma was 73.3% in stage I(11/15), 75.0% in stage II(3/4), 100% in stage III(1/1), and 100% in stage IV(1/1), but there was no significant difference in each stages. CONCLUSION: Telomerase seems to be uniquely associated with malignant transformation of cervix and can be used as a tumor marker. Additional studies are needed to better clarify the biological significance of telomerase expression in cervical tumorigenesis.

Serial neurosonographic examinations are routinely performed at frequent intervals during nursery course of all preterm infants of very low-birth-weight who are admitted to the intensive care nursery of Presbyterian Medical Center from November 1, 1990 to July 30, 1992. After discharge, the following survivors who had received periodic, serial scanning by meas of cranial ultrasonography were longitudinally observed in an interdisciplinary neurodevelopmental follow-up program to a mean corrected age of 13 months. Neurodevelopmental outcome was assessed by means of Vojta's postural reaction and other neurological examinations. The results are as follows: 1) The incidence of PV-IVH in the study was 79%. 2) According to Papile's grading system of PV-IVH, gradel was 20%, gradell was 46%, gradelll was 19%, and grade IV was 13%. 3) The risk factors associated with PV-IVH were birth weight, gestational age, apgar score, ventilator care, RDS, and sepsis. 4) The mortality of PV-IVH was 20% for gradel, 19% for gradell, 44% for gradelll, and 67% for grade lV. 5) According to relationship between PV-IVH and neurodevelopmental outcome, in two of the four subjects with grade lll PV-IVH, moderate/severe CCD was developed. 6) According to relationship between PVE with cysts and nuerodevelopmental outcome, moderate/severe PVE with periventricular cysts larger than 3mm in diameter was associated with development of severe CCD.

The purpose of this study is to examine the factors influencing the allergic rhinitis patients' satisfaction with laser surgery. The data were collected by telephone interviews with 211 patients who visited E university hospital. The statistical methods used for the analysis were factor analysis, reliability test, and hierarchical multiple regression. We find that satisfaction level is a function of not only the surgery outcome but also the socio-psychological experience during treatment. With the improvement in nasal allergic condition, patients were more likely to be satisfied with medical services. And patients who had positive experience with physicians and facilities reported higher satisfaction level. While the surgery outcome explained 68% of the variation of satisfaction level, socio-psychological experience explained 23% of it. This result clearly shows that physicians need to pay attention to the socio-psychological aspect as well as the technical aspect of medical services.

The purpose of this study was to develop the CORE Program for sex offenders and to determine its effectiveness. The CORE Program was designed with an aim to achieve cognitive restructuring, improve the ability to empathize in interpersonal relationships, and enhance self-esteem and intimacy. We conducted this program over 48 sessions for 28 sex offenders. The effectiveness of the program was evaluated using the Interpersonal Responsiveness Index (IRI), Self-esteem Questionnaire (SEQ), UCLA Loneliness Scale (UCLALS), Coping Using Sex Inventory (CUSI), Rape Myth Acceptance Scale (RMAS), and Wilson's Sex Fantasy Questionnaire (WSFQ). The data were analyzed using paired t-tests. Our results showed no significant changes in the SEQ, UCLALS, and IRI scores after the treatment program. However, the scores for the CUSI, RMAS, and WSFQ significantly improved after this program. In this paper, we demonstrate the effectiveness of the CORE Program for sex offenders. We also discuss the limitations of our study and provide suggestions for future research. Our findings indicate that this treatment program should be provided to sex offenders for preventing recidivism.

A case of extrapulmonary silicosis involving abdominal lymph nodes in a 62-year-old man is presented. The patient underwent subtotal gastrectomy and regional lymph nodes dissection for gastric adenocarcinoma of clinical stage III. On gross examination, two separate gastric adenocarcinomas and multiple enlarged lymph nodes mimicking metastatic lesion were noted. Microscopic examination of the enlaged lymph nodes revealed characteristic sclerohyaline silicotic nodules without metastatic adenocarcinoma. Chest roentgenogram showed diffusely scattered multiple tiny nodular lesions in the entire lung fields, particularly the posterior side of both upper lung fields. He had worked in a mine for 18 years and had been exposed to silica for 5 of those years. We report incidentally found, unusual case of extrapulmonary silicosis.
