  • To address the ability of Herba Portulacae(HP) to induce cell death, we investigated the effect of HP on cell viability. Twenty-four hours later, loss of viability occurred following HP exposure in a dose-dependent manner. The treatment of HP, a commonly used herb formulation in Korea, Japan and China, caused a decrease in cell viability. HP also resulted in apoptotic morphology a brightly blue-fluorescent condensed nuclei by Hoechst 33258-staining, and reduction of cell volume. Our results show that 2mg/ml HP induces mitochondria membrane potential collapse. Immunoblotting data also shows that the expression of Bcl-2, antiaoptotic protein, decrease by the addition of HP. This GFP-Bax overexpression system shows that an important pro-apoptotic Bcl-2-family protein, Bax is translocated to mitochondria by the addition of 2mg/ml HP. Inerestingly, MAPK inhibitor study shows that p38 MAPK inhibitor, SB203580 inhibits HP-induced cell death and caspase-3 activation in HP-treated HeLa cells. Furthermore, HP transiently but significantly induces p38 activation. But P38 MAPK inhibitor does not have any effect on the translocation of Bax. Considering these results, HP induces apoptosis via p38 MAPK activation. But the pathway does not involve the translocation of Bax.

  • To address the ability of Kung-Kyung-Ilho-Jeon(KK) to induce cell death, we investigated the effect of KK on cell viability. Forty-eight hours later, loss of viability occurred following KK exposure in a dose-dependent manner. The treatment of KK, a commonly used herb formulation in Korea and China, caused a decrease in cell viability. KK also resulted in apoptotic morphology a brightly blue-fluorescent condensed nuclei by Hoechst 33258-staining, and reduction of cell volume. Our results show that KK induces caspase-3 and -9 activation in a time-dependent manner. In addtion, the translocation of cytochrome c release into cytoplasm has been observed under the presence of $5mg/m{\ell}$ KK. The subsequent loss of mitochondria membrane potential is collapsed by the addition of KK. Our immunoblotting data show that PARP, a well known caspase-3 and -6 substrate, is cleaved by KK. We show that a pro-apoptotic protein, Bax is increased in the presence of KK but that the amount of Bcl-2 is not changed. We suggest that Bax, a critical protein which can regulate channel of mitochondria to release cytochrome c, is a key protein in KK-induced apoptosis of Hela human cervical carcinoma cells

  • Objectives: This study was designed to investigate the effects of PR on ovarian tissue in PCOS rats through measurement of morphological and histo-pathological observations, ovarian size. In addition, effects on expression levels of Insulin like Growth Factor Receptor(IGFR) were also investigated to elucidate related mechanisms. Methods: PCOS was induced by single intermuscular injection with ${\beta}$-Estradiol 17-Valerate(EV) in female rats. Normal group(NOR, n=8) were injected with sesame oil and administrated hard food for five weeks. Control group(CTL, n=8) were injected with EV and administrated hard food for five weeks. CR group(n=8) were injected with EV and administrated hard food mixed CR for five weeks. Then, we measured weights of body and ovary, uptakes of food and water. And we observed morphological and histo-pathological changes of ovary, levels of IGFR. Results: In this experiments, single injection of Estradiol Valerate(EV) induced suppression of weight gain, formation of cysts, increase of IGFR expression. Oral administration of PR prevent decrease of ovarian size significantly. Further more, formation of cystic follicles induced by EV injection is suppressed by PR treatment. Conclusions: These results suggest PR can be used for patients with PCOS to prevent formation of cystic follicles and malfunction of ovary.

  • Purpose: The purpose of this study is to investigate anti-inflammatory effect and immune responses of aqueous extract from Fructus Chaenomelis (FC). Methods: We studied anti-inflammatory effect by means of examining the production of NO(nitric oxide) and expressions of pro-inflammatory cytokine (TNF-$\alpha$(tumor necrosis factor-alpha), IL(Interleukin)-6, IL-12) in the LPS-induced peritoneal macrophages of mice. Also, The western blot analysis has been done to look into the mechanism of anti-inflammatory effect. Results: 1. The FC extract did not have any cytotoxicity in the peritoneal macrophages. 2. The FC extract inhibits the productions of NO, IL-6. IL-12 in the LPS-stimulated peritoneal macrophages of mice, but not of TNF-$\alpha$. 3. The FC extract inhibits the activation of NF-${\kappa}B$(nuclear factor-kappa B) by keeping $I{\kappa}B-\alpha$(inhibitory kappa B-alpha) from degradating, but not of MAPKs(mitogen-activated protein kinases) such as ERK(extracelluar signa 1-regulated kinase), JNK(c-Jun N-terminal kinase), p38. Conclusion: These results show that FC extract inhibits the production of pro-inflammatory cytokines such as IL-6. IL-12. NO by inhibiting NF-${\kappa}B$ activation in the peritoneal macrophages of mice. In conclusion, this experiment suggests that FC extract may be effective for the treatment of acute and chronic inflammation including genitourinary infection.

  • Purpose: The purpose of this study is to investigate the anti-arthritis effects of Jeonsaenghwalhyeoltanggamibang(JHTG) on collagen-induced arthritis(CIA) in mice. Methods: To assess the effects of JHTG on CIA in mice, we conducted several experiments such as analysis of arthritis index, cell count of draining lymph node(DLN) and paw joint, measurement of serum antibody levels and observation of the histological changes of joint. Results: 1. JHTG extract had a suppressive effect on the arthritis index of paw joints in CIA mice. 2. JHTG extract increased the total cell number of DLN, and decreased the total cell number of paw joints in CIA mice. 3. JHTG extract increased the absolute number of various cell surface receptors in DLN, and decreased the absolute number of B220+/CD23+ cells in DLN in CIA mice. 4. JHTG extract decreased the absolute number of CD3+, CD4+, CD11b+/Gr-1 cells in paw joint in CIA mice. 5. JHTG extract didn't decrease the absolute number of CD4+/CD25+ cells in paw joints in CIA mice. 6. JHTG extract decreased levels of total IgM in the serum of CIA mice, but had no effect on levels of collagen II specific antibody. 7. JHTG extract decreased the destruction of articular cartilages and collagen fibers and the proliferation of synovial cells in paw joints from CIA mice. Conclusion: These results indicate that JHTG has clinical potential for the treatment of rheumatoid arthritis by modulating the immune response.

  • The purpose of this research was to identify nursing interventions performed by hospital nurses in Korea. The sample consisted of 311 nurses working in three hospitals. The Nursing Interventions Use Questionnaire developed by the Iowa Intervention Project team was used for data collection. The instrument was translated to Korean using the method of back-translation. Eighteen interventions were performed at least daily. Interventions in the Physiological : Basic domain were most frequently used at least daily. No interventions in the Family and Behavioral domains were used by nurses at least once a day. The most frequently used interventions was Documentation, followed by the interventions Medication : Parenteral, Intravenous(IV) Insertion, Temperature Control, and Shift Report. The intervention performed least often was Reproductive Technology Management. Nurses working in intensive care units on the whole performed interventions most often, while nurses working in obstetric, gynecological, and pediatric units performed them least often. The nurses working in intensive care unit, medical and surgical care units performed the interventions in the Physiological : Basic domain more often than the nurses working in obstetric, gynecological, and pediatric units. The nurses working in obstetric, gynecological, and pediatric units used the interventions in the Family domain more often than the nurses working in the other three units. This study contributes to the documentation of nursrs' work in Korea. Further study will be needed to validate nursing activities of each NIC intervention.

  • Early diagnosis and better prognosis of ovarian cancer is still a challenge. Besides environmental risk factors, genetic factors have established a role in pathogenesis of ovarian cancer. Methods: A case-control and a prospective study design conducted in 224 ovarian cancer patients and 432 controls in Chinese population. MTHFR C677T genotyping was done by PCR-RFLP. Results: Patients with ovarian cancer is associated with a higher less number of delivery and less frequent oral contraceptive use. When potential confounding factors adjusted logistic regression analysis between cases and controls were performed, significant association was obtained for 677T/T genotype and ovarian cancer (OR=3.13, 95% CI=1.59-5.72). Cox regression survival analysis showed individuals carrying T/T genotype had significantly increased HR for death in ovarian cancer patients (HR=2.86, 95% CI=1.27-7.93). In conclusion, we observed that the MTHFR C677T polymorphism is associated with the susceptibility and survival of ovarian cancer in Chinese population.

  • Background: Cancer initiation and progression are controlled by genetic and epigenetic events. One epigenetic process which is widely known is DNA methylation, a cause of gene silencing. If a gene is silenced the protein which it encodes will not expressed. Objectives: 1. Identify the methylation status of BRCA1 in patients with epithelial ovarian cancer (EOC)and assess BRCA1 protein expression in tumor tissue. 2. Examine whether BRCA1 gene methylation and BRCA1 protein are associated with survival of epithelial ovarian cancer patients. Methods: The study design was a prospective-cohort study, conducted at Sardjito hospital, Yogyakarta, Indonesia. Results: A total of 69 cases were analyzed in this study. The data showed that the methylation status of BRCA1 in EOC was positive in 89.9%, with clear protein expression of BRCA1 in 31.9%. Methylation status and expression of BRCA1 were not prognosticators of EOC patients. Menarche, CA125 level, clinical stage and residual tumor were independent factors for prognosis.
