Plexiform neurofibroma is considered a pathognomic of Von Recklinghousen's disease, which involves the deep and large nerve trunk. These are large irregular nerve fascicles which result from an increase in endoneural matrix within individual nerve facicles, without an increased number of nerve fibers. We experenced a case of Von Recklinghausen's disease in a 24 year-old male who had variable cutaneous skeletal, and CNS lesions. He presented multiple neurofibromas, cafe-au-lait spots, and axillary freckles as common cutaneous lesions of NF-I and giant pigmentation, sacral hypertrichosis, and plexiform neurofibroma as unusual cutaneous lesions. Also he had a scoliosis, bowing deformity of the humerous and wedging deformity of the body of the 5th cervical spine as a skeletal manifestation and cortical calcification in the occipital area as a CNS manifestation.

There have been many reports to date regarding the role of GnRH as a local regulatory factor of ovarian function as studies of human and rat ovaries revealed GnRH and its receptor. In recent studies it has been shown that GnRH directly causes apoptosis in the granulosa cells of the rat ovary, and such results leads to the suggestion that the use of GnRH agonist for more stable long term ovarian hyperstimulation in human IVF-ET programs causes granulosa cell apoptosis which may lead to follicular atresia. Therefore this study attempts to determine if granulosa-luteal cell apoptosis occurs in patients during IVF-ET programs in which GnRH agonist is employed for ovarian hyperstimulation. The quality of oocyte-cumulus complexes obtained during ovum pickup procedures were assessed morphologically and then the fertilization rate and developmental rate was determined. Apoptotic cells among the granulosa-luteal cells obtained during the same procedure were observed after staining with Hematoxylin-rosin. The fragmentation degree of DNA extracted from granulosa-luteal cells was determined and comparatively analyzed. There was no difference in the average age of the patients, the number of oocytes retrieved, and fertilization and developmental rates between the FSH/hMG group and GnRH-long group. There was also no difference in the apoptosis rate and pyknosis rate in the granulosa-luteal cells between the two groups. However, when the oocyte-cumulus complexes were morphoogically divided into the healthy group and atretic group without regard for the method of hyperstimulation, the results showed that the number of oocytes obtained averaged 11.09+/-8.75 and 10.33+/-4.53 per cycle, respectively, showing no significant difference, but the fertilization rate (77.05%, 56.99%, respectively, p<0.01) and developmental ,ate (65.96%, 41.51%, respectively, p<0.01) was significantly increased in the healthy group when compared to the atretic group. The degree of apoptosis in the granulosa-luteal cells showed that in the healthy group it was 2.25% which was not significantly different from the atretic group (2.77%), but the pyknosis rate in the atretic group (27.81%) was significantly higher compared to the healthy group (11.35%, p<0.01). The quantity of DNA fragmentation in the FSH/hMG group was 32.22%, while in the GnRH-long group it was 34.27%, showing no significant difference. On the other hand the degree of DNA fragmentation was 39.05% and 11.83% in the healthy group and atretic group, respectively, showing significantly higher increase in the atretic group (p<0.01). The above results suggest that death of granulosa-luteal cells according to the state of the oocyte-cumulus complex is more related to pyknosis rather than apoptosis. Also, the GnRH agonist used in ovarian hyperstimulation does not seem to directly affect the apoptosis of retrieved oocytes and granulosa-luteal cells, and which is thought to be due to the suppression of the apoptogenic effect of GnRH agonist as a result of the high doses of FSH administered.

OBJECTIVE: It is known that mouse embryos before implantation develop in a low oxygen environment of 3- 8% concentration and with antioxidant materials such as vitamins, antioxidant enzymes, ferrous binding proteins, and albumin in follicular and tubal fluids. However, the 20% oxygen culture condition with chemically defined media might be produce an abundance of ROS, and leads to developmental delay or developmental block in vitro. In this study, we attempt to elucidate the relationship between intracellular H2O2 production and embryo development in different oxygen culture conditions of mouse embryos. METHODS: Prenuclear embryos from C57BL/CBA Fl hybrid and ICR mouse were cultured in incubators which provided 5% carbon dioxide, 20% oxygen and 5% carbon dioxide, 5% oxygen. Measurement of H2O2 level in a embryo was performed with DCHFDA(2, 7 -dichlorodihydroflourescein diacetate)and analyzed with Quanti-cell 700, and the number of blastomeres was counted with DAPI( 4, 6'-diamidino-2-phenylindole). RESULTS: Oxygen concentration of the culture medias was significantly higher in the 20% oxygen environment compared to that of 5% oxygen environment. Culture of mice embryos in high oxygen condition leads to high HO concentrations at 2 cell stage and developmental delay or ""2-cell block"" regardless of the strain. But in a 5% oxygen environment, which is similar to in-vivo conditions HO production was suppressed continuously through out culture and development of embryos was definitely improved. CONCLUSION: These results suggest that there is a difference in the production of ROS or protective mechanism according to the mouse strains and stage of development, and it is thought that in-vitro culture in 5% oxygen environment provides stable in vivo equilibrium but in a 20% oxygen environment there is production of ROS which overcome the protective mechanism which leads to cellular damage and embryo developmental delay.

OBJECTIVE: The purpose of this study is to design the web-based dialogue expert system for preventing and managing of habitual substance disorders in adolescents. METHODS: Research process includes the requirement analysis, making of questionnaires, actual survey, and its analysis. Based on the analysis, we designed the web-based dialogue expert system. RESULTS: The habitual substance disorders in adolescents are variable. Our system for managing habitual substance disorders contains the diagnosis of alcoholism, nicotinism, and narcotism. And it analyzes the facts of them based the questionnaires and answer. As the results of the analysis, main reasons in order of the power of influence are belief, will of refusal, personal characteristics, family environment, and psychological personality. Our system suggests the customized solution to conquer that for each adolescent. Moreover, our system also includes the history tracking mechanism to manage the status of each teenager constantly and to make the survey and analysis information. CONCLUSION: With our system, young boys and girls can know their seriousness of alcoholism, nicotinism, and narcotism. And they can get all possible helps through our system. This system will be the interactive and familiar way that anyone all over the world can use for overcoming problems.

BACKGROUND: Pneumonia is the most common cause of death among patients with infectious disease in Korea. However, studies of pneumonia with septic shock in patients presenting to the emergency department are limited. The aim of this study was to investigate the prognostic factors associated with pneumonia with septic shock in patients presenting to the emergency department. METHODS: From January 2008 to September 2014, patients with pneumonia with septic shock admitted through the emergency department were retrospectively examined. RESULTS: Of the 561,845 patients who visited the emergency department, 398 were admitted for pneumonia with septic shock. The 28-day mortality rate in these patients was 36.4%. The independent prognostic factors were old age (>70 yrs) (odds ratio [OR], 2.42; 95%, confidence interval [CI], 1.35-4.32), Acute Physiology and Chronic Health Evaluation (APACHE) II score (OR, 1.04; 95% CI, 1.01-1.08), leukopenia (OR, 3.63; 95% CI, 1.48-8.94), prolonged PT-INR (OR, 2.53; 95% CI, 1.41-4.54), and hypoxemia (OR, 2.88; 95% CI, 1.30-6.38). CONCLUSIONS: A poor prognosis of patients with pneumonia is associated with old age (>70 yrs), increased APACHE II score, leukopenia, prolonged PT-INR, and hypoxemia.
