  • To determine the appropriate concentration of papaverine hydrochloride(PPV) for therapeutic intraarterial infusion against cerebral vasospasm and to measure the mean blood flow velocity of the middle cerebral artery in rabbits. Vasospasm was induced in the experimental groups (3 days after infusion; group 1, n=3, 7 days after infusion; group 2, n=3) and a control group (n=l) by placing a blood clot in the subarachnoid space around the top of the internal carotid siphon. PPV (5 mg/kg) was infused into the internal carotid artery. The vascular diameters of the internal carotid artery (ICA) and middle cerebral artery (MCA) were measured on angiograms before and after infusion. The mean blood flow velocity in the MCA was measured on transcranial doppler sonograms before and 24 hours after infusion. After fixation, the MCA was dissected out, stained, and examined microscopically. After PPV infusion in both groups, vascular dilatation of about $20\%$ was seen. The mean increase in blood flow velocity in the group $1(30\%)$ was smaller than in the group $2(70\%)$. The mean blood flow velocity in the MCA decreased by about $30\%$ in both groups, but increased again after 24 hours nearly to the level before PPV infusion. PPV infusion may be more effective in early stages of vasospasm when vascular walls have fewer histologic changes.

  • Therapeutic hypothermia in cardiac arrest patients is associated with favorable outcomes mediated via neuroprotective mechanisms. We report a rare case of a 32-year-old male who demonstrated complete recovery of signal changes on perfusion-weighted imaging after therapeutic hypothermia due to cardiac arrest. Brain MRI with perfusion-weighted imaging, performed three days after ending the hypothermia therapy, showed a marked decrease in relative cerebral blood flow (rCBF) and delay in mean transit time (MTT) in the bilateral basal ganglia, thalami, brain stem, cerebellum, occipitoparietal cortex, and frontotemporal cortex. However, no cerebral ischemia was not noted on diffusion-weighted imaging (DWI) or fluid-attenuated inversion recovery (FLAIR) sequences. A follow-up brain MRI after one week showed complete resolution of the perfusion deficit and the patient was discharged without any neurologic sequelae. The mechanism and interpretation of the perfusion changes in cardiac arrest patients treated with therapeutic hypothermia are discussed.

  • Women were used as their own controls in the comparison of presterilization and poststerilization menstrual patterns. Five parameters were studied: regularity of cycle length, duration and amount of flow and incidence of dysmenorrhea and intermenstrual bleeding. Three parameters in the electrocoagulation group (regularity of cycle length and duration and amount of flow) and one parameter in the tubal ring group (duration of flow) showed significant changes after sterilization. However, by controlling for the effect of previous contraceptive methods used, no significant menstrual pattern changes following sterilization were discerned in either technique group.

  • Previously, we generated monoclonal antibodies (MAbs) that bound to the surface of human embryonic stem cells (hESCs) in an attempt to discover new hESC-specific surface markers. In this study, MAb 47-235 (IgG1, ${\kappa}$) was selected for further characterization. The MAb bound to the surface of undifferentiated hESCs but did not bind to mouse ESCs or mouse embryonic fibroblast cells in flow cytometric analysis. The antibody immunoprecipitated a 47 kDa protein from the lysates of cell surface-biotinylated hESCs. Identification of the protein by quadrupole time of flight tandem mass spectrometry revealed that 47-235 binds to Ag 243-5 protein of Mycoplasma arginini. BM-Cyclin treatment of the hESCs that reacted with 47-235 resulted in loss of mycoplasma DNA and the reactivity to 47-235. Nevertheless, the hESCs that were reactive to 47-235 maintained self-renewal and pluripotency and thus could be differentiated into three embryonic germ layers.

  • This study is a descriptive study to examine how poem causes effects of literary treatment for the contemporary people and how to improve therapeutic effect with poem by illustrating the process of therapeutic effect by poem. Each poem in the poetry book has a well-organized flow. While those poems are mixed, it can be synapsed into the cognitive system of readers by their taste in the form of introduction, development, turn, and conclusion.' The poetry book is structured with the transition of literary treatment. Such transition structure is embodied in a circle. If poetic contents are positive and creative in such transitive structure, it gives more comfort and excitement to readers increasing therapeutic effect. Therefore, it is very important to progress literatherapy narrative with such creative works.

  • Previously, we reported that overexpression of Opa (Neisseria gonorrhoeae opacity-associated)-interacting protein 5 (OIP5) caused multi-septa formation and growth defects, both of which are considered cancer-related phenotypes. To evaluate OIP5 as a possible cancer therapeutic target, we examined its expression level in 66 colorectal cancer patients. OIP5 was upregulated about 3.7-fold in tumors and over 2-fold in 58 out of 66 colorectal cancer patients. Knockdown of OIP5 expression by small interfering RNA specific to OIP5 (siOIP5) resulted in growth inhibition of colorectal and gastric cancer cell lines. Growth inhibition of SNU638 by siOIP5 caused an increase in sub-G1 DNA content, as measured by flow cytometry, as well as an apoptotic gene expression profile. These results indicate that knockdown of OIP5 may induce apoptosis in cancer cells. Therefore, we suggest that OIP5 might be a potential cancer therapeutic target, although the mechanisms of OIP5-induced carcinogenesis should be elucidated.

  • This study is phenomenological qualitative research about lived experience of recovering alcoholic homeless who had completed Therapeutic Community program. The meaning which is revealed through this study is as in the followed. First, Moving to recovering space. In Therapeutic Community, they have a turning point for new life and new connection with people who watch him carefully. Second, Physical recovery. They are no more lying down on the street. Analogy of Standing can be viewed as being most active in recovery. Third, Positioning on time flow. The recovering of time is represented by accepting past and present as well as looking ahead into the future. Fourth, Settling into network of a relation. They tried to reconnect with society by network of a relation. Their social place is located in a network, not a position. From this present study, the social work implications for the alcoholic homeless are deducted.

  • Background: Although many authors have reported that the median survival time of surgically resected non-small cell lung cancer (NSCLC) was shorter in aneuploid than in diploid determined by flow cytometry, there are few reports about DNA ploidy using bronchial brushing material in all types of lung cancer. Method: The DNA ploidy test results of 109 consecutive patients with lung cancer were analyzed to find the relationship of DNA ploidy and anatomic or physiologic stage. And the differences of the response to various therapeutic modalities according to DNA ploidy were evaluated at least 8 weeks after the begining of the therapy. Results: Numbers of patients with DNA aneuploid pattern or high proliferative activity (S+G2M>22%) were not different among the various cell types of lung cancer. The relationship of DNA ploidy and anatomic or physiologic stage was not significant. However, NSCLC patients with high proliferative activity showed more advanced anatomic stage than those without that (p<0.05). The short-term response rate to therapy depended on the anatomic (p<0.005) or physiologic stages (p<0.05) in patients with NSCLC, and not on DNA ploidy or proliferative activity. Conclusion: DNA ploidy test using bronchial brushing material revealed that high proliferative activity means advanced anatomic stage, but it was not useful to predict the therapeutic response.

  • Geopungdodam-tang(GDT) have been used in oriental medicine for many centuries as a therapeutic agent of apoplexy. The mechanism of GDT on the cerebral blood flow is not known. The purpose of this Study was to investigate effects of GDT on the pial arterial diameter and action mechanism of GDT-induced increased regional cerebral blood flow(rCBF). The changes of regional cerebral blood f1ow(rCBF) was determinated by Laser-Doppler Flowmetry(LDF), and the changes of pial arterial diametet were determinated by video microscopy methods and video analyzer. The results were as follows ; 1. Pial arterial diameter was significantly increased by GDT in a dose-dependent manner. 2. Pretreatment with L-NNA significantly inhibited GDT induced increased rCBF. 3. Pretreatment with methylene blue significantly inhibited GDT induced increased rCBF. 4. Pretreatment with indomethacin inhibited GDT induced increased rCBF. These results suggest that GDT causes a diverse response of cerebral hemodynamics(rCBF and pial arterial diameter). The cerebral hemodynamics is also mediated by nitric oxide synthase, cyclic GMP(guanylyl cydase) and prostaglandin(cyclooxygenase).
