Objective : This study was performed to investigate the relationship between social support and quality of life among cancer patients receiving radiation therapy. Matehals and Methods : The data were collected from 98 patients, who were receiving radiation therapy at two university hospitals located in GwangUJu, used by structured questionnaire. For statistical analyses of the association between quality of life and various characteristics, data were analyzed using t-test, ANOVA, Pearson 's correlation, and multiple regression analysis. Results: 1. There were 56(57.1%) males and 42(42.9%) females. Age ranged from 21 to 82 years. The primary sites of cancer were gastrointestinal tract (24.5%), lung (23.5%), breast (21.4%), and head and neck (11.2%) in order. 2. The mean scores of social, family, and medical support were 4.30 0.58, 4.49 0.78, 4.11 0.65, respectively. The score of quality of life was 5.83 1.63 (range: 1.95 ~ 9.05). 3. An analysis of the association between several factors of patients and quality of life showed that the statistically significant factors were age, the presence of distant metastasis, family support, medical support and social support. 4. As a result of the multiple regression analysis, only social support was significant (β=0.932, P=0.02) with quality of life, but age and presence of distant metastasis were not significant. Conclusion : This suggests that quality of life in cancer patients could be improved by strengthening the social support which consists of family and medical support. Further study would be necessary to evaluate separately several aspects of quality of life among cancer patients.

<P>Amyotrophic lateral sclerosis (ALS) is a fatal neurological disorder characterized by selective degeneration of motor neurons. Mutant superoxide dismutase 1 (SOD1) is often found as aggregates in the cytoplasm in motor neurons of various mouse models and familial ALS patients. The interplay between motor neurons and astrocytes is crucial for disease outcome, but the mechanisms underlying this phenomenon remain unknown. In this study, we investigated whether transient transfection with wild-type and mutant-type SOD1 may lead to amplification of mutant SOD1-mediated toxicity in cortical neurons and astrocytes derived from wild-type and mutant-type (human G93A-SOD1) mice. In transgenic mice expressing either wild- or mutant-type SOD1, we found that green fluorescent protein (GFP)-wtSOD1 was present in the cytoplasm and nuclei of wild-type cortical neurons and astrocytes, whereas GFP-mutant SOD1 was mainly cytoplasmic in wild- and mutant-type cortical neurons and astrocytes. These findings indicate that intracellular propagation of misfolding of GFP-wt or mtSOD1 are possible mediators of toxic processes involved in initiating mislocalization and aggregation. Here, we provide evidence that cytoplasmic aggregates induce apoptosis in G93A-SOD1 mouse cortical neurons and astrocytes and that the toxicity of mutant SOD1 in astrocytes is similar to the pathological effects of ALS on neurons <I>in vitro</I>. Collectively, our results indicate that mtSOD1 probably interacts with wtSOD1 via an unknown mechanism to produce augmented toxicity and may influence aggregate formation and apoptosis.</P>

Holt-Oram Syndrome is an autosomal dominant disorder characterized by the association of upper-limb abnormalities and congenital heart disease. A woman with no family history of genetic disease underwent antenatal sonography at 27 weeks' menstrual age to screen for fetal anomalies. Ultrasonography revealed abnormalities in the upper limbs. The limb abnormalities included abscence of bilateral thumbs and radius: the left humus was short. Pregnancy termination was performed. The postnatal chromosomal analysis revealed a normal 46XX karyotype and the autopsy finding confirmed the Holt-Oram syndrome. We report a case of Holt-Oram Syndrome in fetus with unaffected parents with brief of the literatures.

호산구성 담낭염은 비교적 드문 질환으로 다른 일반적인 원인의 담낭염과 비교하여 증상, 검사실 소견 및 이학적 검사에 있어 차이가 없어, 주로는 수술 후 진단하게 된다. 한편, 호산구성 방광염은 호산구성 담낭염과 마찬가지로 드물게 발생하며 이 역시 조직학적 진단을 통해서만 확진된다. 본 저자들은 우상복부통증으로 내원하여 급성 담낭담관염으로 담낭절제술 시행 후 호산구성 담낭염이 진단된 환자에서, 수술 후에도 경도의 말초혈액 호산구증가증의 지속과 만성 하부 요로 증상으로 인해 경요로방광조직검사 후 호산구성 방광염의 병발을 국내 최초로 확인하였고, 과호산구증가증후군으로 발현한 호산구성 담낭담관염 및 방광염 진단하에, 이에 대해 스테로이드 투약을 통해 증상 및 말초혈액 호산구증가증의 소실을 경험하였기에 문헌고찰과 함께 보고하는 바이다. Eosinophilic cholangiopathy is a rare disease characterized by dense transmural eosinophilic infiltration of the gallbladder and bile duct. It’s clinical and laboratory manifestations are not different from those of other causes of cholangiopathy, and the diagnosis is usually made based on pathologic findings after cholecystectomy. Moreover, the occurrence of eosinophilic cystitis accompanied by cholangiopathy is extremely rare. We report a rare case of hypereosinophilic syndrome manifested as eosinophilic cholangiopathy accompanied with eosinophilic cystitis, for the first time in Korea, in a 49-year-old woman who presented with persistent right upper quadrant pain. After performing imaging study to validate the diagnosis of acute acalculous cholecystitis and cholangitis, an urgent cholecystectomy was performed. Pathologic examination of the excised gallbladder was consistent with eosinophilic cholecystitis. The patient underwent bladder biopsy because there was persistant irritative voiding symptoms combined with constant mild peripheral eosinophilia even after cholecystectomy, and the pathologic findings revealed eosinophilic cystitis. Symptoms and peripheral eosinophilia were improved after steroid therapy for an indicated period.

Purpose : We assessed the utility of the resistance index ratio (RIR) in distinguishing between obstructive and nonobstructive upper urinary tract dilatation in children. Methods : Twenty-three children (7 days-14 years old) with unilateral dilated collecting systems and a contralateral normal kidney were prosectively evaluated by duplex Doppler sonography. We measured the resistance index (RI) of the intrarenal arteries and calculated the RIR. Ninety-six normal kidneys in 48 controls were also evaluated. Results : Twelve kidneys were proved to be obstructed at the ureteropelvic junction, and 11 were found by renal scintigraphy with furosemide and/or by surgery to have nonobstructive dilatation. The mean RIR differed significantly between the obstructed and dilated nonobstructed kidneys (1.16 +- 0.04 versus 1.04 +- 0.04, respectively ; p < 0.01). After surgical correction of ureteropelvic junction obstruction, the obstructed kidneys showed significant drops in the RIR (1.18 +- 0.03 to 1.07 +-0.03, p < 0.01). The RIR showed no statistically significant relationship with age (r = -0.268, p < 0.01); however, the RI declined with increasing age (r = -0.414, p < 0.01). An RIR cut-off value of > - 1.10 provided a god discriminatory level, resulting in a sensitivity of 92%, a specificity of 97%, a positive predictive value of 85%, and a negative predictive value of 97%. Conclusion : An RIR cut-off value of <- 1.10 appears to be an effective parameter for evaluation and follow-up of unilateral obstructive hydronephrosis in children.

<P>We present pure CH<SUB>4</SUB> and CH<SUB>4</SUB>/C<SUB>3</SUB>H<SUB>8</SUB> mixed hydrate phase equilibria formed from a mixture of NaCl (10 wt %) and monoethylene glycol (MEG, 10 and 30 wt %) solutions. As expected for thermodynamic inhibitors, the mixture of salt and glycol causes the hydrate phase equilibrium boundary to shift to lower temperatures and higher pressures, and on increasing the MEG concentration, the hydrate stable region shifted more. The measured experimental data are also compared with a thermodynamic model recently developed, named the Hu-Lee-Sum correlation, showing that the data match well with the predictions. The experimental data were used to calculate the enthalpy of hydrate dissociation. The enthalpies of CH<SUB>4</SUB> hydrates in the mixture of 10 wt % NaCl brine and 10 or 30 wt % MEG were found to be ∼58.7 and 54.63 kJ/mol, respectively, corresponding to structure I hydrates, whereas for the CH<SUB>4</SUB>/C<SUB>3</SUB>H<SUB>8</SUB> (91.98:8.02 mol %) mixed gas system, the enthalpies of dissociation were found to be ∼101.10 kJ/mol (10 wt % NaCl + 10 wt % MEG) and 95.34 kJ/mol (10 wt % NaCl + 30 wt % MEG), confirming the mixed hydrates formed structure II. We also performed Raman analysis for CH<SUB>4</SUB> hydrates and CH<SUB>4</SUB>/C<SUB>3</SUB>H<SUB>8</SUB> mixed hydrates in the NaCl and MEG system and investigated their spectroscopic behavior and hydrate structure.</P> [FIG OMISSION]</BR>
