BACKGROUND: There has been a lot of changes in prehospital medical environment with development of EMSS(emergency medical service systems). Especially in out-of-hospital cardiac arrest, the patients could survive when they are moved to the hospitals earlier. The purpose of this research is to know the status of EMSS in Korea by analyzing CPR(cardiopulmonary resuscitation) outcomes of out-of-hospital cardiac arrest patients at 3 hospital in the western area of Seoul and Incheon. METHODS: From July 1997 to June 1998, we collected data about out-of-hospital cardiac arrest victims at Ewha Womens University Mokdong Hospital, Catholic University Medical College St. Mary Hospital, and Kachon University Chung Ang Gil Hospital. We used same record form based on the 'Utstein Style'. RESULTS: CPR were performed in 265 out-of-hospital cardiac arrest patients at 3 hospitals. One hundred twelve(42.3%) patients recovered the spontaneous circulation at least once and eight(3.0%) patients discharged alive. One hundred ninety four(73.2%) patients died of medical causes, one hundred two(38.5%) cardiogenic and ninety two(34.7%) non-cardiogenic, and seventy(26.4%) patients died of traumatic causes. Initial EKG showed VT/VF(ventricular tachycardia/ventricular fibrillation) in thirty one(11.7%) patients, asystole in one hundred fifty one(57.0%) patients and other rhythms in eighty three(31.3%) patients. Among one hundred two cardiogenic cardiac arrest patients, two(2.0%) patients was discharged alive. CONCLUSION: Overall survival rate of out-of-hospital cardiac angst patients was 3% which was poorer than that of the western country. The proportion of the cardiogenic cause was 3% which was only hart of the western country. VT/VF is relatively not common as a initial EKG rhythm. These differences might be due to difference in the prevalence pattern of out-of-hospital cardiac arrest as well as prematurity of the EMSS.

Ultrasonography is a very useul diagnostic modality for the evaluation of clinically suspicious abdominalmasses in infants and children, especially in assessing their existence, size,location, origin and internalconsistency. Authors analyzed and present ultrasonographic findings of 92 pathologically and/or clinically provenpediatric abdominal masses that were studied and treated in Chonnam University Hospital during recent 4 years. Theresults were as follows: 1. The most common originating site was kidney(26 cases: 28.3%), followed bygastrointestinal tract (21 cases: 22.8%), genital organ(17 cases: 18.5%), non-renal retroperitoneum (13cases:18.5%), hepatobilary tract (12 cases:13.0%), and anterior abdominal wall (3 cases: 3.3%) in ordre offrequency. 2. The most common mass was hydonephrosis(18 cases: 19.6%). Neuroblastoma(7 cases:7.6%),hepatoblastoma, ovarian teratoma, periappendiceal abscess and abdominal tuberculosis(6 cases: 6.5%, respectively),Wilms tumor(5 cases: 5.4%) were next in order of frequency. 3. The sex distribution is rather similar, that is ,male 42(45.7%) and female 50(54.3%), but characteristically choledochal cyst(2 cases) and genital mass(17 cases)were found only in females. Considering age distribution, 78 cases(84.8%) were found within the range of one to 15years of age. The rest, 14 cases(15.2%), were under the age of one year. 4. With ultrasonography, the diagnosis ofhydronephrosis could be made easily in every case and we could evaluate its severity and level of obstruction withhigh accuracy. 5. All Wilms tumor were large, round or oval, sharply marginated and relatively homogenous solidmasses. 6. All neuroblastomas were irregular shaped, poorly defined, heterogeneous solid masses. Tumorcalcification and extension across the midline were noted in 6 cases(85.7%) and 5 cases(71.4%), respectively. 7.All periappendiceal abscesses had irregular thickened wall and posterior acoustic enhancement: 4 cases (66.7%)among them were mixed echo pattern and 2 cases(33.3%) ehco free. 8. Among the 6 abdominal tuberculoses, 2 wereseen as irregularly defined solid masses, 1 as conglomeration of multiple hypoechoic nodulles and 3 as mixedpatterns. 9. All hepatoblastomas were seen to be poorly marginated solid masses with more echogenicity thanadjacent normal hepatic echo in 5 cases except one. 10. Among the 6 ovarian teraomas, 4 cases were cystic and 2cases solid. Acoutic shadowing was seen in 3 cases. 11. Choledochal cyst (2 cases), hydrops of gallbladder(1cases) and cyst of pancreas head(1 cases) had similar ultrasonic appearance as a large elliptical systic mass,but, it was important in differential diagnosis to ascertain the existence of gallblader and the connectionbetween the cyst and bile duct.

PURPOSE: The pathways of pain conduction in brain are not well known. Also, differences of somatic pain conduction between adult and young age have not been fully elucidated. This study was conducted to investigate any differences in the expression of c-Fos protein between adult and young rats after somatic pain was induced by formalin. METHODS: Male rats (n=70) were injected subcutaneously with 0.1mL of 5% formalin in the plantar surface of right hindpaw. Rats were sacrificed at 30 minutes, 1 hour, 2 hours, 6 hours, 24 hours after noxious formalin stimuli to hindpaws and rectums. Rat brains were removed and sliced in rat brain matrix. Brain slices were coronally sectioned at interaural 5.70-6.70mm. Serial sections were immunohistochemically reacted with polyclonal c-Fos antibody. The numbers of c-Fos protein immunoreactive neurons in cingulate cortex, primary somatosensory area, and hippocampus were examined and analyzed statistically with Mann-Whitney U test. RESULTS: The number of c-Fos protein immunoreactive neurons in the cingulate cortex, primary somatosensory area and hippocampus peaked at 2 hours after formalin-induced pain on adult rats. The number of c-Fos protein immunoreactive neurons in the cingulate cortex, primary somatosensory area and hippocampus peaked at 1 hour after formalin-induced pain on young rats. The numbers of c-Fos protein immunoreactive neurons of adult groups were higher than that of young groups at all points of time. CONCLUSION: The immunoreactions in adult group expressed more intense than those in young group. Earlier expression of immunoreactions in young group suggests of faster conduction of pain, compared to those in adult group. Larger number of c-Fos protein immunoreactive neurons were found within specific regions in both groups. These results could provide some basic knowledge in understanding the mechanism and control of pain in pediatric group.

BACKGROUND: Parent's alcohol drinking not only influences their health but also their children. This research was designed to assess the family function of children who were affected by parent's alcohol drinking. METHODS: Questionnaire survey was performed on 208 high school students (129 males and 79 females) in Daejeon from March to April, 2005. We defined the students whose CAST (Children of Alcoholics Screening Test) score was 6 or more as children of alcoholics (COA) group. Then, we evaluated the family function by family APGAR score between the COA group and the control group. RESULTS: Among the total, 36 (27.9%) male and 27 (34.1%) female students were in COA group. There was a significant (P<0.01) negative correlation between the CAST score and the family APGAR score in all students. In boys, there was no significant correlation between the CAST score and the family APGAR score, but in girls, there was significant negative correlation (P<0.01). Mean family APGAR score of the COA group was significantly (P<0.05) lower than that of the control group in all students. In boys, there was no significant difference, but in girls, the COA group's family APGAR score was significantly lower than the control group's score (P<0.05). CONCLUSION: The high school students, especially girl students, who were affected by parent's alcohol drinking showed a lower family APGAR score. Therefore, family physicians need to evaluate the family function when encountering students similar to COA group.

Rapidly proliferating cancer cells require energy and cellular building blocks for their growth and ability to maintain redox balance. Many studies have focused on understanding how cancer cells adapt their nutrient metabolism to meet the high demand of anabolism required for proliferation and maintaining redox balance. Glutamine, the most abundant amino acid in plasma, is a well-known nutrient used by cancer cells to increase proliferation as well as survival under metabolic stress conditions. In this review, we provide an overview of the role of glutamine metabolism in cancer cell survival and growth and highlight the mechanisms by which glutamine metabolism affects cancer cell signaling. Furthermore, we summarize the potential therapeutic approaches of targeting glutamine metabolism for the treatment of numerous types of cancer.

Background/Aims: Extracellular vesicles (EVs) are secreted from various types of cells and have specific functions related to their origin. EVs are observed in the small intestinal lamina propria (lpEVs), but their function remains unclear. This study aimed to investigate the role of lpEVs. Methods: LpEVs were isolated from antigen (ovalbumin [OVA])-fed mice (lpEVs/OVA), and administrated to the naïve mice for 5 days before induction of lung inflammation. Afterwards, the mice were sensitized and challenged with OVA to evaluate the role of lpEVs/OVA in the regulation of immune tolerance. Results: The isolated lpEVs/OVA were sphere-shaped, bi-layered vesicles of approximately 50 to 100 nm in size. The vesicles expressed CD81, A33 antigen, and major histocompatibility complex (MHC) class II on the surface. When administrated to naïve mice, the lpEVs/OVA migrated to the spleen. Intraperitoneal lpEVs/OVA administration to naïve mice decreased the immune response against sensitized antigen in a CD4+FoxP3+T cell-dependent manner. Conclusions EVs are actively secreted from small intestinal epithelial cells to deliver information about orally administered antigens to immune cells, which will facilitate the modulation of the immune response by acting as an intercellular communicasome.

Non-alcoholic fatty liver disease (NAFLD) is emerging as a world-wide health problem and is currently recognized as a hepatic manifestation of metabolic syndrome. It is an umbrella term to describe a wide range of diseases from simple steatosis to non-alcoholic hepatosteatosis (NASH) and NSAH-related liver cirrhosis. NAFLD is mainly associated with insulin resistance which allows increased free fatty acid (FFA) flux to the liver by increasing lipolysis from adipose tissue, triggering macrophage/immune activation, decreasing skeletal muscle glucose uptake, and increasing de novo lipogenesis. Increased FFA pool in the liver, in turn, increases lipotoxic intermediates, such as ceramides, diacylglycerols, and lysophosphatidylcholines, which are responsible for mitochondrial dysfunction and endoplasmic reticulum stress, resulting in inflammation of the liver. When inflammation is severe enough to affect stellate cells, hepatic fibrosis can be induced.

PURPOSE: This study was conducted to investigate the effects of blood flow restriction and different support surfaces for bridge exercises on the thickness of the transverse abdominis and multifidus, which are trunk-stabilizing muscles. METHODS: The study's subjects were 45 adults who were divided into three groups that performed bridge exercises over a six-week period on their respective support surfaces after blood flow restriction. Changes in the thickness of the subjects' transverse abdominis and multifidus muscles were measured using ultrasonography before the experiment, then three and six weeks after the experiment. The changes in each variable over time were analyzed using a repeated-measures analysis of variance (ANOVA). RESULTS: The transverse abdominis showed significant differences in muscle thickness with regard to time and the interaction between time and each group (p<0.05), but no significant differences with regard to changes among groups (p>0.05). The multifidus showed significant differences in muscle thickness with regard to time, the interaction between time and each group, and changes between groups (p<0.05). CONCLUSION: Blood flow restriction and different support surfaces for bridge exercises led to significant differences in the thickness of the transverse abdominis and multifidus. This study's results may be used as the basis for future studies and for rehabilitation in clinical practice.

We report herein the case of a 38-year-old woman with Cushings syndrome caused by bilateral adrenocortical adenomas. The adrenal tumor on the left side hypersecreted cortisol and no findings of cortisol hypersecretion from the adrenal tumor on the right side were observed on bilateral adrenal vein samplings. Both adrenal tumors were resected and histologically without any findings of nodular hyperplasia. The left adrenal tumor was histologically diagnosed as a so-called black adenoma. These data imply that the adrenal adenomas developed primarily from the adrenal gland itself, and that one of the tumors was well differentiated and secreted excess hormones, while the other remained in cell proliferation without hypersecretion.
