BACKGROUND: Smoking increases the risk of respiratory, cardiac diseases and cancer. This study is to ascertain the relationship between passive smoking, the modes of residence, its location and the immunoglobulin values as well as the eosinophil counts in relation to child patients suffering from bronchial or cardiac asthma. METHODS: The research was conducted at a general hospital with cooperation of 242 patients who had been hospitalized 1991 through 1995. We compared the average values of immunoglobulin between the groups of exposed and non-exposed to smoking by T-test. A same work for residential modes was done by T-tests, while the data regarding the residing locality were processed by ANOVA. RESULTS: Each values of TEC, IgE, IgA, and IgM in both groups has been analysed but spelling no significant differences. The group residing in apartments showed lower value of IgM than those of flats. CONCLUSIONS: The reason the IgM value of apartments is lower than that of flats is due to the difference of living quarters. This signifies the modes of residence may as well affect the IgE value.

PURPOSE: To examine the fate of muscle-derived stem cells (MDSC) after injection into different host conditions and provide an insight for their mechanism of action. MATERIALS AND METHODS: MDSCs differentiated in vitro towards the endothelial lineage and transfected with lentivirus tagged with green fluorescent protein (GFP) were injected into two animal models mimicking vascular diseases: hindlimb ischemia and carotid injury models. Injected cells were tracked at the site of injection and in remote organs by harvesting the respective tissues at different time intervals and performing immunofluorescent histological analyses. Stem cell survival was quantified at the site of injection for up to 4 weeks. RESULTS: MDSCs were successfully tagged with fluorescent material GFP and showed successful implantation into the respective injection sites. These cells showed a higher affinity to implant in blood vessel walls as shown by double fluorescent co-stain with CD31. Quantification of stem cell survival showed a time-dependent decrease from day 3 to 4 weeks (survival rate normalized against day 3 was 72.0% at 1 week, 26.8% at 2 weeks and 2.4% at 4 weeks). Stem cells were also fo und in distant organs, especially the kidneys and liver, which survived up to 4 weeks. CONCLUSION: MDSCs were successfully tracked in different vascular disease models, and their fate was assessed in terms of cell survival and distribution. Better understanding of the donor cell properties, including their interaction with the host conditions and their mechanism of action, are needed to enhance cell survival and achieve improved outcomes.

Aspirin is one of the popular non -steroid anti -inflammatory drugs used in the management of pain. This study was performed to investigate the effects of aspirin on c -Fos expression in rat CNS after inducing somatic pain with formalin. Male S.D. rats were injected subcutaneously with 0.1 ml of 5% formalin in the plantar surface of right hindpaw. For experimental group, aspirin was administered orally before injection of formalin. Asprin -untreated group was utilized as the control group. Rats were sacrificed at 0.5, 1, 2, 6 and 24 hours after formalin injection. Rat brains were removed and sliced in rat brain matrix. Brain slices were coronally sectioned at interaural 5.70 ~6.70 mm. Serial sections were immunohisto-chemically reacted with polyclonal c -Fos antibody. The numbers of c -Fos protein immunoreactive neurons in the cingulate cortex, primary somatosensory area, and hippocampus were counted and analyzed statistically with Mann - Whitney U test. Results were as follows: 1. Higher numbers of c -Fos immunoreactive neurons were found in the cingulate cortex, primary somatosensory area and hippocampus. 2. Both aspirin -treated and -untreated groups, numbers of c -Fos immunoreactive neurons were significantly higher all time points than formalin -untreated group, which peacked at 2 hours. 3. The numbers of c -Fos immunoreactive neuron of the aspirin -treated group were less compared to the aspirin - untreated group at each time point. In conclusion, these results provide some basic knowledge in understanding the mechanism and control of formalin - induced somatic pain.

Fetal bilateral renal agenesis is a lethal congenital anomaly. An early and reliable prenatal diagnosis is extremely important as it may offer options for pregnancy termination as early as possible. The criteria for the ultrasonographic diagnosis of bilateral renal agenesis are severe oligohydramnios, nonvisualization of the bladder, and the empty renal fossae. However, severe oligohydramnios makes it difficult to diagnose the disease because of poor sonographic resolution. We present a case of fetal bilateral renal agenesis diagnosed by ultrasonography after amnioinfusion at 19 weeks gestation.

Neutropenia is defined as an absolute neutrophil count (ANC) of <1,500/microliter, and the severity of neutropenia generally can be graded as mild (1,000-1,500/microliter), moderate (500-1,000/microliter), or severe (<500/microliter). This stratification aids in predicting the risk of pyogenic infection because the susceptibility to life-threatening infections is significantly increased in patients with prolonged episodes of severe neutropenia. Especially cancer-related neutropenia carry significant mortality. Neutropenia can develop under various conditions such as decreased bone marrow production, the sequestering of neutrophils, and increased destruction of neutrophils in the peripheral blood. Neutropenia is classified according to the etiology as congenital or acquired, with the latter further defined according to the etiology or pathology. The clinical result is increased risk for infection, which is directly proportional to the severity and duration of the neutropenia. The typical workup of neutropenia starts with a 6-week period in which complete blood counts are measured twice weekly to document the persistence of the neutropenia and whether a cyclic pattern is present. When persistent neutropenia is diagnosed and no spontaneous recovery occurs within 3 months, a more extensive evaluation is advised. Treatment is usually unnecessary for most patients with severe neutropenia, as the majority of patients have a good prognosis. However, for patients who have severe and frequent infections, treatment with filgrastim may prevent infectious complications and improve quality of life.

PURPOSE: Previously, Kawasaki disease (KD) treatment with low-dose aspirin was administered for 6–8 weeks after the acute phase. However, inflammatory marker levels normalize before 6–8 weeks. In this study, we aimed to investigate the clinical outcome of short-term low-dose aspirin treatment based on inflammatory and thrombotic marker levels. METHODS: We performed a retrospective review of the medical records of patients with KD who were hospitalized at Chungnam National University Hospital between September 2012 and May 2014. When fever subsided, low-dose aspirin treatment was started. Inflammatory (white blood cell count, erythrocyte sedimentation rate, and C-reactive protein) and thrombotic markers (D-dimer) were monitored at follow-ups conducted in 1- to 2-week intervals. The low-dose aspirin administration was terminated when both markers were normalized and no cardiovascular complications were observed. RESULTS: Eighty-four patients with KD (complete KD, n=49; incomplete KD, n=35) were enrolled. The inflammatory and thrombotic marker levels were normalized within 3–4 weeks on average. At the beginning the low-dose aspirin treatment, 9 patients had coronary artery lesions but 75 did not. When the low-dose aspirin administration was terminated at the time the inflammatory marker levels were normalized, no new CALs developed during the follow-up at 6–8 weeks. CONCLUSION: Most of the inflammatory marker levels were normalized within 3–4 weeks after the acute phase of KD. New cardiovascular complications did not develop during the course of the short-term aspirin treatment based on the inflammatory marker levels, clinical findings, and echocardiography.

The main purpose of this methodological study was to develop an assessment tool and intervention protocol for child and family with childhood cancer at early diagnosis stage. The assessment tool and intervention protocol was developed by extensive literature review and consultation with experts. Review of nine domestic and sixty-six international journal articles were done to identify stress, interventions, coping strategies and adjustment of children with cancer and their family. Results were as follows; First, assessment at the early diagnosis stage need to include information on patient, family, and patient/family attitude toward diagnosis and treatment. Second, intervention protocol for children with cancer includes control physical symptoms, manage the side effects of chemotherapy and diagnostic or therapeutic procedures, control emotional responses, provide support and information, assist decision-making and adjust to environment. Third, intervention protocol for family includes controlling emotional responses, provision of informations, inducing family support to patient, improving family cohesion, supporting siblings and supporting spiritual growth. In conclusion, the early diagnosis stage in cancer treatment is important for child and family since this stage greatly affects the overall adjustment of child and family to live with cancer. Therefore, pediatric nurses need to be sensitive to the need of patient/family and systematically manage their needs at this stage.

BACKGROUND: Tumor necrosis factor(TNF) has been considered as an important candidate for cancer gene therapy based on it9 potent anti-tumor activity. However, since the efficiency of current techniques of gene transfer is not satisfactory, the majorities of current protocols is aiming the in vitro gene transfer to cancer cells and re-introducing genetically modified cancer cells to host In previous study, it was shown that TNF-sensitive cancer cells transfected with TNF-α CDNA would become highly resistant to TNF. Understanding the mechanisms of TNF-resistance in TNF-α gene transfected cancer cells would be an important step for improving the efficacy of cancer gene therapy as we]1 as for better understandings of tumor biology. This study was designed to evaluate the role of new protective protein synthesis in the acquired resistance to TNF of TNF-α gene transfected cancer cells. METHOD: We transfected TNF-α c-DNA to WEHI l64, a murine fibrosarcoma cell line, using retroviral vector (pLT12SN(TNF)) and confirm the expression of TNF with PCRf ELISA, MTT assay. Then we determined the TNF resistance of TNF gene transfected cells(WEHI 164-TNF) and the changes of TNF sensitivities after treatments with actinomycin D(transcription inhibitor) and cycloheximide(translation inhibitor). RESULTS: WEHI 164 which was sensitive to TNF became resistant to TNF after being trsnsfected with TNF-α gene and the resistance to TNF was partially reversed after treatment with actinomycin D, but not with cycloheximide. CONCLUSION: The acquired resistance to TNF after TNF-α gene transfection may be associated with synthesis of some protective proteins.

Werniche's encephalopathy is clinically characterized by the acute onset of global confusion, ataxia, gaze paresis, and nystagmus. It result from a deficiency in thiamine, an essential coenzyme in intermediate carbohydrate metabolism. The prompt use of thiamine prevents progression of the disease and reverses those lesions that have not yet progressed to the point of fixed structural change. We experienced a case of Wemiches encephalopathy associated with hyperemesis gravidarum, which happens to the patient who are injected only dextrose without thiamine. Therefore, we emphasize the need of thiamine replacement in hyperemesis gravidarum.
