C-erbB-2 oncoprotein has been known to act as growth factor receptor responsible for the regulation of cellular growth, proliferation and differentiation and has been demonstrated in a number of cancers by immunohistochemical as well as matrix blotting techniques. Breast and ovarian cancer patients, whose tumor cells have amplification or overexpression of this oncoprotein, have been suggested to have worse prognosis. Yet, there are only a few studies on c-erbB-2 oncoprotein expression in transitional cell carcinoma(TCC) of the bladder. The aim of this study was to examine c-erbB-2 oncoprotein expression in bladder cancer to assess its potential as a useful prognostic marker in transitional cell carcinoma of the bladder. Deparaffinized tumor specimens from 42 patients with TCC of the bladder and 3 normal bladder tissue specimens were utilized. C-erbB-2 oncoprotein expression was detected by immunohistochemical analysis and then correlated with conventional prognostic variables such as histologic tumor grade, stage and DNA ploidy. In addition, we related the expression of c-erbB-2 oncoprotein to indicators of cellular proliferative activities such as proliferating cell nuclear antigen(PCNA), mean number of silver nucleolar organizer regions(AgNORs) per nucleus, flow cytometric S-phase fraction(CPF) and proliferation index(PI). The incidence of c-erbB-2 oncoprotein expression in Ash grade IV TCC of bladder was higher than that in Ash grade II and III (Chi-square test, p<0.05). The incidence of positive immunoreaction was higher in cases with muscle invasion and metastasis than in superficial tumors with statistical significance(p<0.05). In addition, statistical significant correlation was noted between c-erbB-2 oncoprotein expression and PCNA expression rate. But there were no significant differences in c-erbB-2 oncoprotein expression to DNA ploidy, PI nor SPF by flow cytometry and mean number of AgNORs per nucleus. The results of this study suggests that the c-erbB-2 oncoprotein together with other predictive parameters may serve to provide a phenotypic profile which permits more accurate forecasting of bladder cancer behavior and may prove to be useful in the future as an important guide to specific anti-tumor therapy.

Chronic bronchiolitis is a condition associated with cigarette smoking, and later associated with pulmonary parenchymal alteration and progressive deterioration of lung function. Early respiratory bronchiolitis was produced in Sprague-Dawley rats by indirect inhalation of cigarette smoke daily in a smoke exposure chamber designed by authors for 1 month. Experimental group A (n=5) was sacrificed after having smoked 30 cigarettes, group B (n=5) after 80 cigarette, and group C (n=7) after 140 cigarettes, respectively. Examination of morphologic changes in the lungs was done on light microscope, transmission and scanning electron microscopes. Light microscopically, increase in number of goblet cells in the bronchial mucosa, brown-pigmented macrophages in the alveoli, multifocal alveolar collapse adjacent to the bronchioles, dilatation of alveolar ducts and alveolar spaces were observed. Transmission electron microscopically, irregularly shaped Clara cells, alveolar wall collapse, and focally type I epithelial cell injury were seen. Scanning electron microscopically, scattered alveolar collapse, irregular dilatation of alveolar ducts, alveolar spaces and interalveolar pores (pores of Kohn) were seen. The terminal and respiratory bronchioles showed morphological alteration of Clara cells, but no evidence of cellular bronchiolitis or bronchiolar obstruction. We conclude that sidestream smoke induces an early respiratory bronchiolitis including aggregates of brown pigmented macrophages and varying degrees of structural alteration of adjacent pulmonary parenchyma.

BACKGROUND: Ictal semiology is very important in inferring the seizure generating brain structures. Asymmetric tonic posture(one elbow is extended while the other is flexed during tonic phase) may occur during generalized tonic clonic(GTC) seizure. The lateralizing value of asymmetric GTC seizure is controversial. OBJECT: To evaluate the lateralizing value of asymmetric GTC seizure, we undertook this study. METHODS: The videotapes of 148 patients who underwent video-EEG monitoring in Seoul National University Hospital Epilepsy Monitoring Unit from September 1994 to July 1995, were reviewed, The localization of seizure focus was based on the findings of interictal & ictal EEG, brain MRI, interictal & ictal SPECT, PET, cognitive function test and invasive EEG. The asymmetric tonic postures were classified into 4 classes: 1. Consistent ; the asymmetric posture lasting from the onset of seizure generalization to seizure termination 2. Initial ; the asymmetric posture starting from the onset of seizure generalization, but followed by symmetric tonic flexion or extension. 3. Terminal ; the asymmetric posture following the symmetric tonic flexion or extension. 4. Alternating ; the asymmetric posture alternating during seizure. RESULTS: Total 747 seizures were reviewed. There were 81 asymmetric seizures in 37 patients. 3 patients (4 asymmetric seizures) had generalized onset and these patients were excluded. There were 32 consistent, 20 initial, 22 terminal and 3 alternating asymmetric GTC seizures. In 21 out of 34 patients (62%), the extended arm was contralateral to seizure onset. Especially in the case of consistent and initial asymmetric posture, the extended arm was contralateral to seizure onset in 94% and 100% respectively. CONCLUSION: The consistent and initial asymmetric posture during GTC seizure provide good lateralizing information.

Megaloblastic anemia induced by Vitamin B12 deficiency is a disorder caused by impaired DNA synthesis. It has been previously thought to be rare in children, however, recent studies suggest that this condition is more common than previously recognized. Deficiency can lead to a wide spectrum of hematologic and neuropsychiatric disorders. Especially in children, it often presents with nonspecific manifestations, such as developmental delay, irritability, weakness, and failure to thrive. Early diagnosis and prompt treatment might resolve these complications, but permanent neurologic damage may have already occurred. We experienced two cases of Megaloblastic Anemia induced by Vitamin B12 deficiency and report them with a brief review of the literature.

PURPOSE: It is necessary to develop a proper payment system for more health care facilities to provide hospice and palliative cares. In deciding the proper level of payment for hospice per diem fee, willingness to pay (WTP) may provide one of the critical information. This study was conducted to determine WTP for hospice care and to analyze those factors affecting WTP. MATERIALS AND METHODS: A contingent valuation method with a double-bounded dichotomous-choice model was used. Interview survey was organized and conducted by a survey company from April 4 to 18, 2008. The mean WTP was calculated through an infinite integration of survival functions. RESULTS: The average willingness to pay was found to be 42,240 Korean won (KRW) (USD 35), with the amount becoming higher as hospice services were deemed more necessary or where average monthly household income was higher. The amount was also higher among male respondents than females. CONCLUSION: To compare this WTP with actual cost (32,500 KRW) (USD 27) for hospice care. To facilitate hospice service, hospice specific payment system should be developed. This study provides information regarding the general public's preference of hospice service and their WTP for hospice care, and it may be useful in the decision-making process.

OBJECTIVE: To observe the capability of fertilization and embryo development including blastocyst formation of the oocytes in simple media after thawing of the cryopreserved cumulus-free mouse oocytes by vitrification method. METHODS: Oocytes were collected from 5 to 6 weeks old ICR female mice, and were denuded from the cumulus cells by 0.1% hyaluronidase. Recovered mature oocytes in study group were cryopreserved by vitrification method using EM grid for 5~7 days. In brief, oocytes were exposed in dPBS containing 1.5 M EG and 5.5 M EG+1 M sucrose for 2.5 minutes and 20 seconds each, and then executed vitrification by plunging in LN2 after loading on EM grid. Thawing treated by exposure of 1, 0.5, 0.25 and 0.125 M sucrose solution for 2.5 minutes each in order and used for experiments. Spermatozoa aspirated form the epididymis of 12 weeks old ICR male mice were used for insemination after capacitation. T6 media containing 0.4% BSA were used for fertilization and development. RESULTS: Survival and fertilization rates after thawing were 76.9% and 79.6% respectively. Fertilization rate was lower (p<0.005) than that of control group (92.9%). There was no difference in embryo developmental rates from 2-cell to morula, however, the blastocyst formation rate and mean cell numbers of blastocysts in study group (63.3%, 58.9+/-9.2) were lower compared with those of control group (76.1%, 63.5+/-8.9). CONCLUSION: Vitrification is an effective method for mouse mature oocyte cryopreservation with high survival and fertilization rate after thawing. And in simple media, fertilization rates and embryo development of frozen-thawed mouse oocytes are satisfactory.

PURPOSE: This study is aimed to find out the incidence of late endocrine complications in children who were treated for childhood cancer. METHODS: We reviewed the medical records of 60 patients who was treated for childhood cancer and evaluated various pituitary hormonal functions after completion of treatment from July 1985 to September 2004 at Kyungpook National University Hospital. RESULTS: Forty-four boys (73.3%) and sixteen girls (26.7%) were involved in the study and their ages ranged from 2 months to 14 years. Twenty-four patients were treated with chemotherapy with cranial irradiation and thirty-six were treated with chemotherapy only. The diagnoses included ALL (n=27, 45.0%), AML (n=2, 3.3%), malignant lymphoma (n=13, 21.7%), brain tumor (n=5, 8.3%), MDS (n=1, 1.7%), and other solid tumor (n=12, 20.2%). Forty-four (73.3%) out of the 60 patients had an additional endocrine abnormality. Growth hormone deficiency (GHD) was identified in 44 children (73.3%). Incidence of GHD was significantly higher among those who had received cranial irradiation (91.6% vs. 61.1%) (P=0.009) but this kind of difference was not found in ALL 27 patients (93.7% vs. 72.7%) (P=0.131). Only one patient was diagnosed as primary hypothyroidism, two patients were diagnosed as primary hypogonadism, and these three patients showed growth hormone deficiency. No patient had abnormalities of ACTH and cortisol. CONCLUSION: We thought that late endocrine complications were very common in childhood cancer survivors. Accordingly, we recommended that we should focus on endocrine abnormalities while treating and following up the patients.

BACKGROUND/AIMS: The effects of curcumin on the growth of human colon cancer cell lines, HT-29 and WiDr cells were examined and the effects of 5-fluorouracil (5-FU) were also studied. METHODS: The growth of HT-29 and WiDr cells were examined by counting cell number on two and four days treatment with 1-40 micrometer of curcumin, and 0.1 microgram/mL, 0.3 microgram/mL of 5-FU. The reversibility of curcumin was examined on one day to seven days treatment with 10 micrometer curcumin after seeding to 2 10(4) cells/well. To examine the inhibitory effects of curcumin, cell cycle analysis was done on the HT-29 cells after four days treatment with 20 micrometer curcumin. RESULTS: Curcumin inhibited the growth of HT-29 and WiDr cells in a dose-dependent fashion. The growth rate of the group in which curcumin was removed by media change 24 hours after the treatment of curcumin was not different from that of control group. Curcumin combined with 5-FU markedly inhibited the growth of HT-29 and WiDr cells compared to curcumin or 5-FU alone. After four days treatment of HT-29 cells with 20 micrometer curcumin, the fraction of cells in G2-M phase was 35.3% in curcumin group, much higher than 13.8% of the control group. CONCLUSIONS: Curcumin significantly inhibited the growth of HT-29 and WiDr cells in a dose- dependent, reversible fashion.

PURPOSE: The aim of this study is to find out the role of HEPA filter equipped lamina air flow room reverse isolation for the treatment of anticancer drug induced febrile neutropenic patients. METHODS: Antibiotics and antifungal agents were promptly administered to twenty six patients with febrile neutropenic following chemotherapy from January 2003 to July 2005 at the Department of Pediatrics, Kyungpook National University Hospital, Daegu, Korea. And if possible, they were treated in the aseptic room. RESULTS: Nineteen patients recovered and seven patients died of infectious causes among twenty six patients. Fourteen patients had microbiologically defined infection, seven patients had clinically defined infection, and five patients had unexplained fever. The causes of infection were sepsis, pneumonia and urinary tract infection. The etiologic pathogens were Gram negative bacilli, 6 (42.9%) ; Gram positive cocci, 3 (21.4%) ; and fungus, 5 (35.7%). The dead group showed lower leukocyte count and higher CRP than the survived group. All dead patients showed disseminated intravascular coagulation syndrome (DIC). Nine of the ten patients (90%) who were treated in the aseptic room survived and ten of the sixteen patients (62.5%) in the general ward survived. CONCLUSION: The infection-related mortality of febrile neutropenic patients following chemotherapy is influenced by the early and adequate use of antimicrobial agents, DIC, neutrophil count and CRP. The isolation in the aseptic room increased the survival rate, but it was not statistically significant.
