  • This study was done to provide a basis for home health care management for women following Cesarean delivery. Furthermore it was initiated as an possible application of home health care in the future. In this study, client selection criteria was developed by the researcher and assessment tools for home health care, recording system and problem oriented recording system were revised from Jun's(1993) methods. The selection criteria tool for home health care for women who had a Cesarean delivery was structured and consisted of five areas : physical status, functional status, psychological-emetional status, educational needs status and environmental status. The structured assessment tool consisted of general items, obstetric history, past medical history, methods of feeding, medications taken before ad-mission, laboratory results, discharge instructions, discharge medications, family tree, economic status, environmental status, a map, health assessment of women and their newborns. The visit note consisted of the date : nursing problems : nursing process including initial assessment : nursing goals : visit plan : health status of the postpartum women and their newborn : nursing diagnoses : nursing implementation evaluation : summary : next visit plan and revision. The problem oriented recording system consisted of the date, problem numbers, nursing diagnoses, problem appearance date, problem resolution date. The results of the research are as follows : The seven cases having had a Cesarean delivery were discharged on an average on the 5th day after the Cesarean birth. The total number of home visits was 13. According to Cordon's functional health patterns the total possible nursing diagnoses was 34 diagnoses for the methers and their newborns. Among the 34 diagnoses, there were 13 diagnoses in the health perception /management pattern, 7 in the psychosocial health perception / management pattern, 8 in the psychosocial self-perception, 2 in the nutrition / metabolism pattern of physical function, 2 in the knowledge deficit of newborn management, anxiety related to newborn management, knowledge deficit related to disease process of new-born, anxiety related to disease process of newborn anxiety related to prognosis of baby's condition, knowledge deficit related to newborn jaundice each appeared once. The changes in the number of nursing diagnoses was related to not the number of visits but to the number of nursing diagnoses decreasing. The con-tent of the home health care was categorized ac-cording to assessment, direct care, counseling, education, family care. The recommendation based on the results of this research are Home health care nurses for Cesarean postpartum women and their neonates requires comprehensive knowledge of pregnancy, delivery, and the postpartum period and of the neonate so that they can provide appropriate care and holistic views. Most of cases terminated after the second visit, this outcome may be related to the subjects being discharged on the 5th day after delivery. Therefore, study done with earlier discharge after delivery may have different outcome. It is very hard to assess psychological aspects that need follow-up and to develop communication channels.

  • P2X receptors are membrane-bound ion channels that conduct $Na^+,\;K^+$, and $Ca^{2+}$ in response to ATP and its analogs. There are seven subunits identified so far ($P2X_1-P2X_7$). $P2X_2$ receptors are known to be expressed in a wide range of organs including brains and adrenal grands. PC12 cells are originated from adrenal grand and differentiated by nerve growth factor or pituitary adenylate cyclase activating poly peptide (PACAP). Previous studies indicate that $P2X_2$ receptor activation in PC12 cells couples to $Ca^{2+}-dependent$ release of catecholamine and ATP. It is known that acidic pH potentiates ATP currents at $P2X_2$ receptors. This leads to a hypothesis that $P2X_2$ receptors may play an important role in PC12 cell differentiation, one of the characteristics of which is neurite outgrowth, induced by the hormones under lower pH. In the present study, we isolated several clones which potentiate neurite outgrowth by PACAP in acidic pH (6.8), but not in alkaline pH (7.6). RT-PCR and electrophysiology data indicate that these clones express only functional $P2X_2$ receptors in the absence or presence of PACAP for 3 days. Potentiation of neurite outgrowth resulted from PACAP (100 nM) in acidic pH is inhibited by the two P2X receptor antagonists, suramin and PPADS ($100\;{\mu}M)$ each), and exogenous exprerssion of ATP-binding mutant $P2X_2$ receptor subunit ($P2X_2[K69A]$). However, acid sensing ion channels (ASICs) are not involved in PACAP-induced neurite outgrowth potentiation in lower pH since treatments of an inhibitor of ASICs, amyloride ($10\;{\mu}M$), did not give any effects to neurite extension. The vesicular proton pump ($H^+-ATPase$) inhibitor, bafilomycin (100 nM), reduced neurite extension indicating that ATP release resulted from $P2X_2$ receptor activation in PC12 cells is needed for neurite outgrowth. These were confirmed by activation of mitogen activated protein kinases, such as ERKs and p38. These results suggest roles of ATP and $P2X_2$ receptors in hormone-induced cell differentiation or neuronal synaptogenesis in local acidic environments.

  • In this study, we investigated the in vitro anti-obesity, anti-cancer activity and single oral dose toxicity of Inonotus xeranticus extracted by methanol (INXM) or ethyl acetate (INXE). In order to investigate anti-obestity effect of Inonotus xeranticus extracts, the 3T3-L1 cells were treated with these extracts at various concentrations(1, 10, 100 and $300{\mu}g/ml$). It was observed that 3T3-L1 cells treated with $100{\mu}g/ml$ of Inonotus obliquus ethyl acetate extract (INOE), INXM and INXE, in the absence of differentiation cocktail (0.5mM isobutylmethylxanthine (IBMX) $1{\mu}M$ dexamethasone, $1{\mu}M$ insulin), differentiated at a rate of 78.5, 80.9, and 76.4% respectively. Differentiation rates of 86.6% and 83.4% were observed in 3T3-L1 cells which were treated with differentiation cocktail at $100{\mu}g/ml$ of INXM and INXE, respectively. The anti-cancer effect of Inonotus xeranticus extracts was investigated using a method of sulforhodamine B in sarcoma 180 cell line. The cells were treated with these extracts (1, 10, 100 and $300{\mu}g/ml$) for 48 hours. The growth of cells which were treated with $300{\mu}g/ml$ of INXM was inhibited by 80.1%. The growth of sarcoma 180 cells which were treated with 100 and $300{\mu}g/ml$ of INXE was inhibited by 74.7% and 64.5%, respectively. In single oral dose toxicity study, no differences were observed between control and treated groups in clinical signs, body weight gains, and feed and water consumptions. The results indicated that Inonotus xeranticus extracts did not show any toxic effects at 2,000mg/kg in mice, and the $LD_{50}$ of these extracts was found to be higher than 2,000 mg/kg in this experiment. From the above results, Inonotus xeranticus methanol and ethyl acetate extracts might have useful clinical applications in the management of cancer and obesity and may also be useful as a medicinal food.

  • Plasmodium vivax reemerged in the Republic of Korea (ROK) in 1993, and is likely to continue to affect public health. The purpose of this study was to measure levels of anti-P. vivax antibodies using indirect fluorescent antibody test (IFAT) in border areas of ROK, to determine the seroprevalence of malaria (2003-2005) and to plan effective control strategies. Blood samples of the inhabitants in Gimpo-si, Paju-si, and Yeoncheon-gun (Gyeonggi-do), and Cheorwon-gun (Gangwon-do) were collected and kept in Korea Centers for Disease Control and Prevention (KCDC). Out of a total of 1,774 serum samples tested, the overall seropositivity was 0.94% (n=17). The seropositivity was the highest in Paju-si (1.9%, 7/372), followed by Gimpo-si (1.4%, 6/425), Yeoncheon-gun (0.67%, 3/451), and Cheorwon-gun (0.19%, 1/526). The annual parasite incidence (API) in these areas gradually decreased from 2003 to 2005 (1.69, 1.09, and 0.80 in 2003, 2004, and 2005, respectively). The highest API was found in Yeoncheon-gun, followed by Cheorwon-gun, Paju-si, and Gimpo-si. The API ranking in these areas did not change over the 3 years. The seropositivity of Gimpo-si showed a strong linear relationship with the API of 2005 (r=0.9983, P=0.036). Seropositivity data obtained using IFAT may be useful for understanding malaria prevalence of relevant years, predicting future transmission of malaria, and for establishing and evaluating malaria control programs in affected areas.

  • This study examined the association of cytokine gene polymorph isms with intrahepatic bile duct wall fibrosis in human clonorchiasis. A total of 240 residents in Heilongjiang, China underwent ultrasonography, blood sampling, and stool examination. Single nucleotide polymorphism (SNP) sites for $IFN-{\gamma}$ (+874 T/A), IL-10 (-1,082 G/A, -819 C/T, -592 C/A), $TNF-{\alpha}$ (-308 G/A), and $TGF-{\beta}1$ (codon 10 T/C, codon 25 G/C) genes were observed with the TaqMan allelic discrimination assay. No significant correlation was observed between individual cytokine gene polymorphisms and intrahepatic duct dilatation (IHDD). Among individuals with clonorchiasis of moderate intensity, the incidence of IHDD was high in those with $IFN-{\gamma}$ intermediate-producing genotype, +874AT (80.0%, P=0.177), and in those with $TNF-{\alpha}$ low-producing genotype, -308GG (63.0%, P=0.148). According to the combination of $IFN-{\gamma}$ and $TNF-{\alpha}$ genotypes, the risks for IHDD could be stratified into high (intermediate-producing $IFN-{\gamma}$ and low producing $TNF-{\alpha}$), moderate, and low (low-producing $IFN-{\gamma}$ and high producing $TNF-{\alpha}$) risk groups. The incidence of IHDD was significantly different among these groups (P=0.022): 88.9% (odds ratio, OR=24.0) in high, 56.5% (OR=3.9) in moderate, and 25.0% (OR=1) in low risk groups. SNP of $IFN-{\gamma}$ and $TNF-{\alpha}$ genes may contribute to the modulation of fibrosis in the intrahepatic bile duct wall in clonorchiasis patients.
