Triclosan is an antimicrobial or sanitizing agent used in personal care and household products such as toothpaste, soaps, mouthwashes and kitchen utensils. There are increasing evidence of the potentially harmful effects of triclosan in many systemic and cellular processes of the body. In this study, we investigated the effects of triclosan in the survivability of cultured rat neural stem cells (NSCs). Cortical cells from embryonic day 14 rat embryos were isolated and cultured in vitro. After stabilizing the culture, triclosan was introduced to the cells with concentrations ranging from $1{\mu}M$ to $50{\mu}M$ and in varied time periods. Thereafter, cell viability parameters were measured using MTT assay and PI staining. TCS decreased the cell viability of treated NSC in a concentration-dependent manner along with increased expressions of apoptotic markers, cleaved caspase-3 and Bax, while reduced expression of Bcl2. To explore the mechanisms underlying the effects of TCS in NSC, we measured the activation of MAPKs and intracellular ROS. TCS at $50{\mu}M$ induced the activations of both p38 and JNK, which may adversely affect cell survival. In contrast, the activities of ERK, Akt and PI3K, which are positively correlated with cell survival, were inhibited. Moreover, TCS at this concentration augmented the ROS generation in treated NSC and depleted the glutathione activity. Taken together, these results suggest that TCS can induce neurodegenerative effects in developing rat brains through mechanisms involving ROS activation and apoptosis initiation.

엔테로바이러스 감염은 신생아에게 흔히 일어나며, 경한 감염에서부터 다기관 부전이나 사망에까지 이를 수 있다. 특히, 출생 시 모체로부터 수직 감염된 신생아들의 경우 심각한 질환에 이르게 될 수 있다. 본 증례의 환아는 모체에게서 엔테로바이러스의 수직 감염이 일어났으며, 파종 혈관내 응고장애, 간염, 그리고 심근염으로 빠르게 진행하였다. 환아가 태어난 시기가 엔테로바이러스의 유병률이 높은 6월인 점, 환아의 어머니와 형제에게서 고열이 있었던 점, 임상 증상 등을 고려하여 저자들은 환아가 엔테로바이러스의 수직 감염 가능성이 있다고 보고 검사와 치료를 진행하였다. 이 환아는 빈맥을 동반한 다양한 형태의 부정맥을 보였으며, 일반적인 치료에 반응을 잘 하지 않았으나, 엔테로바이러스 감염을 조기에 의심하고 치료하여 완전히 회복할 수 있었다. 신생아의 엔테로바이러스 감염에서, 응고장애를 동반한 간염과 심근염이 동시에 오는 경우는 드물다. 본 증례에서, 저자들은 응고장애를 동반한 간염과 다양한 형태의 부정맥을 동반한 엔테로바이러스 수직 감염을 조기에 진단하고 성공적으로 치료하였기에 보고하는 바이다.

Extrahepatic biliary tract and gallbladder injuries following blunt abdominal trauma are uncommon. Traumatic cystic duct transection is even rarer, which has frequently caused missed diagnosis and delayed treatment. An 18-year-old female patient with no past medical history was transferred to the Trauma Center of Kyungpook National University Hospital after falling from a height of approximately 20 meters. She became hemodynamically stable after initial resuscitation, and initial contrast-enhanced abdominal computed tomography (CT) showed right kidney traumatic infarction and multiple intrahepatic contusions with minimal fluid collection but no extravasation of the contrast. She was admitted to the intensive care unit. On the second day of hospitalization, her abdomen became distended, with follow-up CT showing a large collection of intra-abdominal fluid. Laparoscopic exploration was then performed, which revealed devascularization of the gallbladder with complete transection of the cystic duct and artery. Laparoscopic cholecystectomy was performed, as well as primary closure of the cystic duct orifice on the common bile duct using a 4-0 Prolene suture. After surgery, no clinical evidence of biliary leakage or common bile duct stricture was observed.

Parents are primary care taker for the children and have an important role for the assessment and managent of children's pain following surgery. The purpose of the present study was to examine the validity and clinical utilization of the Postoperative Pain Measure for Parents (PPMP) developed by Chambers et al. Subjects were 52 children aged 4-12 years admitted for tonsillectomy and other minor surgery and their mothers. Faces Pain Scale, State Anxiety, and Postoperative Pain Measure for Parents were used. The data were collected by two research assistant on the operation day and 1st day after surgery at hospital during the period of July 20 to August 28, 1998. The results are as follows: 1. Eta correlation coefficient between 15 items of PPMP and child rated pain were calculated. Correlation coefficients were more than .2 for both day. 2. Internal consistency for PPMP were .82 and .83. 3. The scores of the PPMP were 10.73 (SD=3.71) and 9.27(SD=4.07) on the operation day and 1st day after surgery and there was no significant difference between two days(p=.056) On the other hand, there was a significant difference on the child rated pain by Faces Pain Scale between operation day and 1st day after surgery(p=.001). 4. The correlation(Spearman Rho) between PPMP and child rated pain were .40(p=.003) and .56(p=.000). The score of the PPMP and the children's state anxiety were highly correlated on the operation day and 1st day after surgery (.60, .52, p=.000). 5. Partial correlation between PPMP and child rated pain except state anxiety were .18(p=.23) and .48(p=.001) on the opration day and 1st day after surgery. 6. Using a cut-off score 10 out of 15, the measure showed excellent sensitivity (>80%) and moderate specificity (46.15%, 60% ). This study provides preliminary evidence for the use of the PPMP as a valid pain assessment tool with children between the ages of 4-12 years following surgery. It is suggested to explore the validity with a different subjects with other surgery and to examine the validity for infant and younger children.

Purpose. To determine the effects of music therapy on pain, discomfort, and depression for patients with leg fractures. Methods. Data were collected from 40 patients admitted in an orthopedic surgery care unit. The subjects included 20 intervention group members and 20 control group members. Music therapy was offered to intervention group members once a day for 3 days for 30-60 minutes per day. Pain was measured with a numeric rating scale and by measuring vital signs. Discomfort and depression were measured with self-administered questionnaires. Results. Patients who received music therapy had a lower degree of pain than patients who did not receive music therapy as measured by the numeric pain score (p < 0.001), systolic blood pressure (p < 0.01), diastolic blood pressure (p < 0.001), pulse rate (p < 0.001) and respiration (p < 0.001). Patients who were provided with music therapy also had a lower degree of discomfort than patients who were not provided with this therapy (p < 0.01). Effects of Music Therapy on Pain, Discomfort, and Depression for Patients with Leg Fractures Conclusions. These results demonstrate that music therapy is an effective method for decreasing pain and discomfort for patients with leg fractures.

Purpose: This study was to verify the effects of infant massage on weight recovery from physiologic weight loss, physical development of infants, and identity of their mothers. Method: A study with quasi-experimental design with time delay method was conducted from October 20, 2004 through February 20, 2005 with mothers and infants recruited from postpartum care center. 20 infants in the experimental group (once a day massage group) and 22 control group remained for the final analysis. Data were analyzed using SPSS win 11.0 program by frequency, percentage, mean, standard deviation, t-test and $X^2-test$. Results: There was no significant group difference in weight recovery from physiologic weight loss. However, experiment group showed significant increase in weight and chest circumference in 4 weeks after birth compare to the control group. For changes in behavior, experimental group showed more positive behavioral changes. The mothers who conducted massage for their infants showed higher score of identity as mothers. Conclusion: Since massage applied once a day can be still effective on physical growth of the infants, massage training program for mothers should be developed to apply easily for their infants at home. Further study is suggested to identify influencing factors on performed by mothers and identity as mothers.

Objectives: The Regional Cardiocerebrovascular Center (RCCVC) Project designated local teaching hospitals as RCCVCs, in order to improve patient outcomes of acute cardiocerebrovascular emergencies by founding a regional system that can adequately transfer and manage patients within 3 hours. We investigated the effects of RCCVC establishment on treatment volume and 30-day mortality. Methods: We constructed a panel dataset by extracting all acute myocardial infarction cases that occurred from 2007 to 2016 from the Health Insurance Review and Assessment Service claims data, a national and representative source. We then used a panel fixed-effect model to estimate the impacts of RCCVC establishment on patient outcomes. Results: We found that the number of cases of acute myocardial infarction that were treated increased chronologically, but when the time effect and other related covariates were controlled for, RCCVCs only significantly increased the number of treatment cases of female in large catchment areas. There was no statistically significant impact on 30-day mortality. Conclusions: The establishment of RCCVCs increased the number of treatment cases of female, without increasing the mortality rate. Therefore, the RCCVCs might have prevented potential untreated deaths by increasing the preparedness and capacity of hospitals to treat acute myocardial infarction patients.
