Our aim was to identify histologic changes in cervical carcinoma tumor cells due to chemotherapy,by electron microscopic examination. Cisplatin and 5-fluorouracil were used between March 1, 1994 and February 28, 1995 on a total of 16 patients. The treatment schedule consisted of 75 mg/m2 cisplatin via iv with hyperhydration on Day 1, in combination with 1000 mg/m2 5-fluorouracil via continuous iv on Day 1 to 5. The treatment was repeated every 4 weeks with a maxinum of 3 courses. Ultrastructurally, chemotherapy induced apoptosis,indicated by condensation of nucleus and cytoplasm,fragmentation of nuclei, and apoptotic bodies. Due to repeat chemotherapy, increased levels of desmosomes were noted and parts of tumor nests were replaced by mature squamous cells. Tumor nests were reduced in size, mitochondria exhibited swelling, the endoplasmic reticulum was dilated, and infiltration of inflammatory cells increased after chemotherapy. These results suggest that chemotherapy induces apoptosis and injury to the cytoplasm and nuclei of tumor cells. However, the exact selection mechanism of the biochemical pathway of cell death is not fuUy understood. Further study of the molecular biologic actions of cell death after chemotherapy is warranted.

OBJECTIVES: We examined the effects of neurotrophins and insulin-like growth factors on cell death induced by haloperidol, a typical anti-psychotic agent. METHOD: Neocortices from 14- or 15-daysold fetal mice for neuron-glia co-cultures were used for this experiment. RESULT: Twenty-four hours treatment of mouse cortical cell cultures with 30 M haloperidol-induced wide spread neuronal apoptosis characterized by cell body shrinkage, DNA fragmentation and condensation. Concurrent treatment with growth factors, BDNF, NT4/5, IGF-I and IGF-II, protect the neurons from the haloperidol-induced neuronal apoptosis(HINA) in a dose dependent manner(10-100ng/ml). CONCLUSION: The present study suggests the possibility that haloperidol toxicity can be hampered with growth factors. Further study about the mechanism underlying the protective capacity of the growth factors on HINA may lead to the development of the new protective strategy for tardive dyskinesia.

Although pulmonary artery aneurysms are a rare vascular anomaly, they are seen in a wide variety of conditions, such as congenital heart disease, infection, trauma, pulmonary hypertension, cystic medial necrosis and generalized vasculitis. To our knowledge, mycotic aneurysms caused by pulmonary actinomycosis have not been reported in the radiologic literature. Herein, a case of pulmonary actinomycosis complicated by mycotic aneurysm is presented. On CT scans, this case showed focal aneurysmal dilatation of a peripheral pulmonary artery within necrotizing pneumonia of the right lower lobe, which was successfully treated with transcatheter embolization using wire coils.

Owing to the mass production of recombinant human erythropoietin(rHuEPO), anemia in hemodialysis patients is effectively treated by intravenous or subcutaneous injection of rHuEPO at each dialysis session. But considerable portion of patients being injected rHuEPO have the resistance of EPO treatment. The most common cause of EPO resistance is caused by functional and storage iron deficiency and followed by chronic inflammation, hyperparathyroidism and aluminum intoxication in its incidence. But the rHuEPO resistance is not fully explained by these causes. In the present study, the relationship between nPCR reflecting daily protein intake and the weekly doses of rHuEPO required to maintain hemoglobin levels at approximately 10gm/dL was analyzed in 34 hemodialysis patients All subjective patients of 34 hemodialysis were injected rHuEPO subcutaneously and divided into two group:Group A composing 22 hemodialysis patients is nPCR<1.0gm/kg/day and Group B with 12 hemodialysis patients is nPCR>=1.0gm/kg/day. There were no significant differences in age, duration of hemodialysis, serum ferritin, serum iron, TIBC, transferrin saturation(%) of each group. The patients who had serum ferritin below 100 micro gm/dL or transferrin saturation(%) below 20% were excluded in this study. The weekly rHuEPO doses in patients with Group B was lower than those of patients with Group A(58.7627+/-20.465IU/kg/week vs 80.4317+/-38.6258IU/kg/week, P=0.041). Moreover Serum albumin levels in Group A were significantly lower than those of Group B(3.6522+/-0.4461gm/dL vs 4+/-0.3606gm/dL, P=0.031) and Kt/V in Group B were significantly higher than those of Group A (1.145+/-0.2049+/-1.4021+/-0.2981, P=0.021). Serum parathyroid hormone levels were significantly higher in Group A than those of Group B(171.9783+/-150.3378 pg/dL vs 72.8809+/-79.7226 pg/dL, P=0.049). But other various factors including serum aluminum, body mass index and acute phase reactant proteins such as C-reactive protein and ESR had no significant differences in each group. CONCLUSION: Our result showed that nPCR presenting daily protein intake is related with rHuEPO response and the patient's nutritional status. So we think that the nutrition aspect in EPO treatment should be considered. However, to prove this relationships completely between nutritional factors and rHuEPO response, further study shoud be needed.

PURPOSE: Isolated noncompaction of the ventricular myocardium(INVM) can present as heart failure or arrhythmias in a child. It is a rare disorder, characterized by prominent trabecular meshwork and deep intertrabecular recesses. We still know little about the diagnosis, symptoms, and clinical outcomes of INVM. METHODS: We included in our study 6 patients who showed ventricular noncompaction on echocardiography. Patients were diagnosed as INVM were excessively prominent trabeculations with deep intertrabecular recesses were found on echocardiography. Patients who had other complex heart lesions such as pulmonary atresia with intact ventricular septum in addition to ventricular noncompaction, were excluded. RESULTS: Age at presentation ranged from 1 day 7 years, with follow up being as long as 6 years. Symptoms at initial presentation were heart murmur, paroxysmal supraventricular tachycardia, cyanosis, feeding intolerance, ventricular tachycardia, and cardiomegaly at fetal screening. Prominent trabeculations and intertrabecular recesses were observed at left ventricular apex in all six patients. All patients were alive at last follow-up. One patient showed WPW syndrome on electrocardiography. Echocardiography revealed decreased systolic function in 4 patients, and decreased systolic and diastolic function in 1 patient. One patient is currently asymptomatic. CONCLUSION: Six patients were diagnosed with INVM with various symptoms at initial presentation. Echocardiography is the most important tool in the diagnosis of INVM due to its morphological characteristics. INVM can rarely be the cause of long term systolic dysfunction, and early detection by echocardiographic screening may be beneficial.

Metabolic acidosis is a well-recognized complication of chronic hemodialyzed patients. The metabolic acidosis in stable hemodialyzed patients is mainly resulted from the consequences of the inability to excrete nonvolatile acid and the patients daily protein intake. So severe metabolic acidosis in patients on hemodialysis is known as an independent determinant of protein catabolic rate and high mortality rate but the moderate degree of metabolic acidosis in stable patients on maintenace hemodialysis can be explained by the patients nutritional status. On the other hand, patients having adequate daily protein intake could have lower total CO2 levels than those of patients having inadequately lower daily protein intake. To identify this relationship, we analyzed correlations between pre-hemodialysis total CO2 and various factors reflecting the patient's nutritional status in 37 patients on stable hemodialysis. The total CO2 was ranged from 15.6 to 26.5mMol/L. Among various factors, total CO2 had negative linear correlation with normalized protein catabolic rate(nPCR) reflecting the patient's daily protein intake indirectly(Y= -0.0371X+1.75, r=-0.1319, P=0.014). Moreover, metabolic acidosis having CO2 lower than 18mMol/L may modulate protein kinetics as showing steeper slope than those of more than 18mMol/L(Y=-0.1321 X +3.342, r2=0.1074 vs Y=-0.03373X+1.7543 r2=0.1001, P=0.0001). However other factors including serum albumin, body mass index, pre-hemodialysis BUN, and Kt/V, had no correlation with the total CO2. The result suggested that moderately lower pre- hemodialysis total CO2 ranging from 18 to 26.5 mMol/L was usually resulted from the high intake of the patient's daily protein intake and should be of no concern in stable patients on maintenance hemodialysis and it may use as a parameter of nutritional status. However metabolic acidosis having CO2 lower than 18mMol/L may modulate protein-kinetics, which may make the protein catabolic rate increased and can not reflect the patient's nutritional status. But it should be recommended that further studies should be needed to confirm this factor.

OBJECTIVE: To investigate the efficacy of commonly available analgesics in the management of delayed-onset muscle soreness (DOMS) over an 8-day period, and to compare the efficacy between aspirin and acetaminophen. METHOD: Forty-two subjects were recruited. DOMS was induced by using the isokinetic dynamometer (KinCom(R)) in standardized fashion in the nondominant knee extensor with subjects seated at 30 degree-angle velocity. Subjects were asked to extend their non-dominant knee with concentric method and to hold the knee with eccentric flexion force at 30 degree-angle velocity, with maximal efforts. On this way, they did 10 repetitions, and then 3 cycles. We categorized four groups (n=10, for each group), that were control group with no medication, placebo group with placebo medication (antacid tablets), aspirin group with medication of 900 mg of aspirin, and acetaminophen group with medication with 3,900 mg of acetaminophen. Visual Analogue Scale (VAS: twice a day, until on day 8). and McGill Pain Questionnaire (MPQ: on day 1 and 3) were measured. RESULTS: We didn't find any significant difference of peak VAS score and relief time between four groups (P>0.05), The score of MPQ was not different between four groups (P>0.05). CONCLUSION: We concluded that the medication may not be beneficial, at least at the doses stated, in the management of DOMS.

OBJECTIVES: This study aimed to investigate the effects of resilience on posttraumatic stress symptoms and dissociation and whether depression mediates the relationships between resilience and posttraumatic stress symptoms and dissociation. METHODS: A total of 115 firefighters participated in the study. Data were collected via the Life Events Checklist, Impact of Event Scale-Revised, Dissociative Experience Scale, Beck Depression Inventory, and Connor-Davidson Resilience Scale. Structural equation modeling and path analysis were applied to estimate the relationships between resilience, depression, posttraumatic stress symptoms, and dissociation. RESULTS: Greater resilience was associated with lower posttraumatic stress symptoms and dissociation, and the relationship between them was fully mediated by depression. CONCLUSIONS: Specific aspects of depression may help explain the relationships between resilience and posttraumatic stress symptoms and dissociation. Tailored prevention programs and treatments based on resilience and depression may prevent posttraumatic stress symptoms and dissociation in firefighters and improve treatments outcomes among firefighters with posttraumatic stress symptoms and/or dissociation.
