Endometriosis is classically defined as the growth of endometrial glands and stroma at extrauterine sites. Although it is a common gynecological problem accompanied by chronic pelvic pain, infertility, and adhesion formation, the etiology of this disease is unknown. Endometriosis pathogenesis may involve endocrine and immune dysfunction since uterine endometrial growth is regulated by sex hormones in concert with bioactive mediators produced by uterine immune and endocrine cells. Thus, exposure to environmental toxicants disrupting endocrine and immune responses potentially affect the development and progression of endometriosis.

Since 1950s' we have come to take a deep interest in matrimonial communication as the theories of family therapy though communication came to extend. In the rapid changing modem society, especially, the dysfunctional aspect of the communication rather than functional one tends to grow high because married couples who suffer from isolation and solitary in social life want to satisfy their unfilled desire through matrimonial communication and apt to be hurt easily by their attitudes and behaviors. When these discrepancies in dysfunctional aspect take place repeatedly, the conflict between married couple which is bad in their psychological effects go from bad to worse and influence their somatic symptoms. This study was attempted to examine the relationship between dysfunctional communication patterns of married couple and complaint degree of housewives psychosomatic symptoms and to use as basic materials focusing on nursing system centered around family, which aims to reach the family centered culture of Korea. To gain the aims, some surveys were peformed at Seoul, Chinju and some areas of Kyeongki province, and the study materials were collected from 70 wives who were encountered by 12 pastrolists majoring in clinical pastrol of ‘Y’ Theological Graduate School and from neurotic patients of those who visited the internal Medicine depts of 1 university hospital and 4 hospitals ‘J’ city, among whom they used dysfunctional communication pattern in their married life. And data collection was peformed from Feb. 22, 1988 to April 22. In the survey, four types of dysfunctional communication presented by Song Sung-Ja were used as the survey tool. And the complaint degree on Psychosomatic symptoms was measured by the classification according to the complaint degree of housewives's psychosomatic symptoms through pretest after content validity, in which the housewives who dysfunctional communication wert surveyed. To learn matrimonial Communication patterns that have an effect on housewives psychosomatic symptoms in the surveyed.

Objective : The purpose of this study was to examine the correlation between handwriting skills and praxis. Method : Participants consisted of 50 normal children who were the second-grade students at an A elementary school in Kim-hae. They didn't have a visual dysfunction, an auditory dysfunction, and a disease or an injury in arms and hands. They could follow examiners' directions properly. They were administered the Postural Praxis and the Praxis on Verbal Command of the Sensory Integration and Praxis Tests(SIPT)(Ayres, 2000) and the handwriting skill test which was made with reference to foreign literatures. It was conducted from October 19, 2004 to December 17, 2004. The data were analyzed with non-paired t-test, ANOVA, and Pearson correlation coefficient. Results : 1. Total handwriting score and praxis according to gender of children showed the statistically significant differences(p<0.05). 2. Total handwriting score correlated with praxis(p<0.05) and handwriting speed did not correlate with praxis. 3. Postural Praxis and Praxis on Verbal Command according to handwriting groups showed the statistically significant differences(p<0.05). 4. Among the standards of the handwriting skill test, accuracy of letter form, identity of letter size, spacing between letters and words, placing text on lines, error existence, and letter out of regular square correlated with the Postural Praxis(p<0.05), and accuracy of letter form, identity of letter size, and placing text on lines correlated with the Praxis on Verbal Command(p<0.05). Conclusions : The correlation between handwriting skills and praxis will help occupational therapists to provide fundamental and various treatment programs for children who are referred for the poor handwriting. But more studies in handwriting skills and praxis are necessary to decide which component of handwriting skills is related to praxis.

The water extract of Chongmyung-tang has been traditionally used for treatment of memory-disorder in oriental medicine. This study was designed to investigate the protective mechanisms of Chongmyung-tang on β-amyloid or H₂O₂-induced cytotoxicity in Neuro 2A cells. The water extract of Chongmyung-tang significantly reduced both β-amyloid or H₂O₂-induced cell death and apoptotic characteristics through reduction of intracellular peroxide generation. Also, it inhibited the mitochondrial dysfunction including the disruption of mitochondria membrane permeability transition(MPT) and the modulation in expression of Bcl-2 family proteins in H₂O₂-treated H9c2 cells. Furthermore, pretreatment of quercetin inhibited the activation of caspase-3, in turn, degradation of ICAD/DFF45 were completely abolished in H₂O₂-treated cells. Taken together, that data suggest that the protective effects of the water extract of Chongmyung-tang against β-amyloid induced oxidative injuries may be achieved through modulation of mitochondrial dysfunction.

Central to developing new treatment strategies for late onset sporadic Parkinson's disease (PD) and early onset familial PD is resolving the enigma of the specific vulnerability exhibited by substantia nigra dopamine (DA) neurons despite multiple risk factors. Neuropathological evidence from both human and experimental models of PD firmly supports a significant role for oxidative stress (OS) and mitochondrial dysfunction in the death of nigral DA neurons. Largely unknown are the genes underlying selective susceptibility of nigral DA neuron to OS and mitochondrial dysfunction and how they effect nigral DA cell death. To overcome the paucity of nigral DA neurons as well as the dilution effect of non-DA cells in brain tissues, we have developed wild type DA cell line model, SN4741 and mutant DJ-1 (-/-) DA cells, appropriate for microarray analysis and differential mitochondrial proteomics. Mutations in the DJ-1 gene (PARK7), localized in cytoplasm and mitochondria, cause autosomal recessive early onset PD. Through microarray analysis using SN4741 cells followed by validation tests, we have identified a novel phylogenically conserved neuroprotective gene, Oxi-a, which is specifically expressed in DA neurons. The knockdown of the gene dramatically increased vulnerability to as. Importantly as down-regulated the expression level of the gene and recovery of its expression via transient transfection exerted significant neuroprotection against as insult. We also have identified altered expression of mitochondrial proteins and other familial PD genes in DJ-1 (-/-) mutant cells by differential mitochondrial proteomics. In DJ-1 (-/-) cells the knockdown of the other familial PD genes (Parkin and PINK1) dramatically increased susceptibility to as. Thus, further functional characterization of the Oxi-$\alpha$ gene family and the mitochondrial alteration in the DJ-1 (-/-) cell model will provide the rationale for the neuroprotective therapy against both sporadic and familial PD.

Objective : The water extract of Seokchangpowonji-san (SWS) has traditionally been used for treatment of dementia in oriental medicine. However, little is known about the mechanism by which the water extract of SWS rescues cells from neurodegenerative disease such as Alzheimer's disease. Methods & Results: This study was designed to investigate the protective mechanisms of SWS on $\beta-amyloid$ or $H_2O_2$-induced$ cytotoxicity in neuro 2A cells. $H_2O_2$ markedly decreased the viability of neuro 2A cells, which was characterized by apparent apoptotic features such as membrane blebbing as well as fragmentation of genomic DNA and nuclei. However, the water extract of SWS significantly reduced $H_2O_2-induced$ cell death and apoptotic characteristics through reduction of intracellular peroxide generation. Also, the. extract prevented the mitochondrial dysfunction including the disruption of mitochondria membrane permeability transition (MPT) and the modulation in expression of Bcl-2 family proteins in $H_2O_2­treated$ neuro 2A cells. Furthermore, pretreatment with SWS inhibited the activation of caspase-3, and in turn, degradation of ICAD/DFF45 was completely abolished in $H_2O_2-treated$ cells. Conclusion: Taken together, the data suggest that the protective effects of the water extract of SWS against $\beta-amyloid$ induced oxidative injuries may be achieved through modulation of mitochondrial dysfunction.

The water extract of Danchunhwan(DCH) has been traditionally used for treatment of dementia damage in oriental medicine. However, little is known about the mechanism by which the water extract of DCH rescues cells from neurodegenerative disease such as Alzheimer's disease. This study was designed to investigate the protective mechanisms of DCH on ${\beta}$-amyloid or $H_2O_2$-induced cytotoxicity in SH-SY5Y neuronblastoma cells. ${\beta}$-amyloid and $H_2O_2$ markedly decreased the viability of SH-SY5Y cells, which was characterized with apparent apoptotic features such as membrane blebbing as well as fragmentation of genomic DNA and nuclei. However, the water extract of DCH significantly reduced both ${\beta}$-amyloid or $H_2O_2$-induced cell death and apoptotic characteristics through reduction of intracellular peroxide generation. Also, the water extract of DCH prevented prevented the mitochondrial dysfunction including the disruption of mitochondria membrane permeability transition (MPT) and the perturbation in Bcl-2 family protein expressions in $H_2O_2$-treated SH-SY5Y cells.

Purpose : ARC syndrome refers to an association of arthrogryposis, renal tubular dysfunction, and cholestasis. The VPS33B gene was recently identified as the causative gene. So far, 41 cases of ARC syndrome have been reported worldwide, and it has rarely been reported in Korea. This study was conducted to report the clinical findings of seven ARC syndrome cases in Korean children, focusing especially on renal tubular dysfunction. Methods : The hospital records of 7 cases diagnosed as ARC syndrome at Severance Hospital between Mar. 1995 and Aug. 2005 were reviewed and analyzed. Results : Of the 7 cases, 4 were boys and 3 were girls. Six patients(85$\%$) were born with normal birth weight at term, and one was born at preterm. All cases presented with cholestasis and severe jaundice. According to the type of arthrogryposis described by Brown et al, type 3 and 4 were found in 2 patients and type,6, 7, and the undistributed type in one patient respectively. Other associated clinical findings were as follows : failure to thrive in 6(85$\%$), lax skin in 5(71$\%$), and gray platelet syndrome in 4(57$\%$). Urine analysis revealed 6 cases(85$\%$) with proteinuria, 3(43$\%$) with hematuria, 5(71$\%$) with glycosuria, 2(29$\%$) with phosphaturia and 2(29$\%$) with calciuria. Serum electrolytes showed 4 cases(57$\%$) with hyponatremia, 3(43$\%$) with hypokalemia, and 1(14$\%$) with creatinine elevation. Renal tubular dysfunctions were diagnosed as renal tubular acidosis in 6 cases(85$\%$), nephrogenic diabetes insipidus in 2(29$\%$), and Fanconi syndrome in 2(29$\%$). During the follow-up period, 2(29$\%$) had no treatment, 5(85$\%$) had continuous supplementation to correct the electrolyte imbalance and acidosis, and 1(14$\%$) had dialysis. Only one patient had a family history of ARE syndrome in a sibling. Four cases(57$\%$) were diagnosed at the mean age of 8.2 months, and one case was lost during follow-up. Ages of the survived 2 cases were 13 and 25 months, respectively. Conclusion : The rare disease of ARC syndrome Is associated with severe renal dysfunction. However, this study revealed that the renal manifestation of ARC syndrome in Korean children is relatively mild and survival rate is higher than that of previous studies. Contrary to previous reports, this study showed that familial cases are rare and sporadic occurence is possible in Korea. Thus, the diagnosis of this syndrome requires a careful evaluation of the venal function in cases of congenital arthrogryposis, and a mandatory genetic counseling of affected family for prevention of familial occurance.

The chronic fatigue immune dysfunction syndrome (abbreviated CFIDS or CFS) is a disorder characterized by debilitating fatigue(over 6 months.), along with cognitive, musculoskeletal, and sleep abnormalities. The etiology of this illness is unlikely to be a single agent. Findings to date suggest that physiological and psychological factors work together to predispose and perpetuate the illness. Diagnosis is made difficult by the nonspecific clinical findings and no available diagnostic testing. With no known cause or cure for the chronic fatigue and immune dysfunction syndrome, treatment is based on relieving symptoms and improving the quality of life of affected patients. There is emerging evidence that chronic fatigue syndrome may be familial. In the future, studies will examine the extent to which genetic and environmental factors play a role in the development of chronic fatigue syndrome. Most patients with CFS have psychiatric problems such as a generalized anxiety disorder, or major or minor depression, therefore, these mental health disorders may be correlated with the pathophysiology of the CFS. The treatment for CFS must be individualized, due to the heterogeneity of the CFS population. Also the treatment of CFS is built on a foundation of patient-physician relationship, respect and advocacy.

Purpose: The unmet medical service needs of caregivers critically influence their caring for terminal cancer patients, but not much research has been done in this regard. Thus, the purpose of this study is to investigate the association between caregivers' characteristics and their unmet medical service needs. Methods: The survey was conducted with 109 family caregivers of terminal cancer patients admitted to four hospice units. The data were collected from March 2014 through December 2014 using a structured questionnaire. The unmet medical service needs were measured using 14 items which were adopted and modified by authors. Results: Seven areas of unmet medical service needs were shown to be significant. A well-educated group showed stronger needs for counsel about cancer screening and complementary-alternative medicine and health supplement food. A never-smoked group was identified with less need for sexual dysfunction counsel. Counsel about family and personal relations was more necessary for current drinkers and current workers, and less necessary for the married. Insurance counsel was more needed for a no-religion group. Occupation counsel was less necessary for healthy patients. Financial support was less necessary for the married group. Conclusion: Based on the results, it is highly recommended to further investigate the unmet medical service needs of family caregivers for terminal cancer patients and causes of the unmet needs.
