Aim: To determine prognostic value of blood parameters on overall and progression-free survival in cases received adjuvant radiotherapy and chemotherapy with diagnosis of stage I-III breast cancer. Materials and Methods: We retrospectively reviewed files of 350 patients with non-metastatic breast cancer who were treated in the Radiation Oncology Department of Kayseri Teaching Hospital between 2005 and 2010. Pretreatment white blood cell (WBC), neutrophil, monocyte, basophil and eosinophil counts, and the neutrophil/lymphocyte ratio (NLR) and platelet lymphocyte ratio (PLR) were recorded. The relationship between clinicopathological findings and blood parameters was assessed. Results: Overall, 344 women and 6 men were recruited. Median age was $55.3{\pm}0.3$ years (range: 22-86). Of the cases, 243 (61.4%) received radiotherapy while 329 (94.3%), received chemotherapy and 215 (61.4%) received hormone therapy. Mean overall survival (OS) and progression-free survival (PFS) was 84.4 and 78.8 months, respectively. During follow-up, 48 patients died due to either disease-related or non-related causes. Local recurrence was detected in 14 cases, while distant metastasis was noted in 45 cases. In univariate analysis, age, pathology, perinodal invasion were significantly associated with overall survival, whereas gender, stage and hormone therapy were significantly associated with progression-free survival. In multivariate analysis, histopathological diagnosis (OR: 0.3; 95%: 0.1-0.7; p=0.006) and perinodal invasion (OR: 0.1; 95% CI: 0.1-1.3; p=0.026) were significantly associated with overall survival, whereas tumor stage (OR: 2.1; 95% CI: 0.0-0.7; p=0.014) and hormone therapy (OR: 2.1; 95%: 1.2-3.8; p=0.010) were significantly associated with progression-free survival. Conclusions: It was found that serum inflammatory markers including WBC, neutrophil, lymphocyte and monocyte counts, and NLR and PLR had no effect on prognosis in patients with breast cancer who underwent surgery and received adjuvant radiotherapy and chemotherapy.

Recently, there have been many researches to automate processing and analysing image data in medical field, due to the advance of image processing techniques, the fast communication network and high performance hardware. In this paper, we design and implement the system based on the multi-layer neural network model to be able to analyze, differentiate and count blood cells in the peripheral blood image. To do these, we segment red and white-blood cell in blood image acquired from microscope with CCD(Charge-coupled device) camera and then apply the various feature extraction algorithms to classify. In addition to, we reduce multi-variate feature number using PCA(Principle Component Analysis) to construct more efficient classifier. So, in this paper, we are sure that the proposed system can be applied to a pathological guided system.

Objectives : In Oriental Medicine, hyperlipidemia is considered as phlegm retention (痰飮) and blood stasis (瘀血). Typhae pollen helps remove blood stasis and hemorrhage, and it also has an effect of relieving pain caused by blood stasis. The purpose of this study is to investigate the preventive effects of Typhae pollen on diet-induced hyperlipidemia in rats. Methods : Thirty-two male Sprague-Dawley rats were divided into normal, control and treated groups. The control and treated groups were fed with a 1.5% cholesterol diet over 4 weeks, and extract of Typhae pollen was administered to the treated group during the same period. Blood samples were collected from each animal at 0 and 4 weeks and used for the blood chemical analysis. Animals were sacrificed at 4 weeks and chemical analysis was performed on the collected liver samples. Results : The serum total cholesterol ($122.45{\pm}4.96mg/dL$), LDL-cholesterol ($54.27{\pm}4.95mg/dL$), and triglyceride ($122.00{\pm}7.33mg/dL$) values of the treated group were significantly lower compared with the serum total cholesterol ($147.91{\pm}7.22mg/dL$), LDL-cholesterol ($81.91{\pm}8.34mg/dL$), and triglyceride ($169.27{\pm}12.34mg/dL$) values of the control group. The liver total cholesterol (TEX>$230.18<{\pm}18.81mg/dL$) values of the treated group were significantly higher compared with the liver total cholesterol ($178.54{\pm}$10.11mg/dL) values of the control group. Conclusions : On the basis of these results, it is confirmed that Typhae pollen has preventive effects on diet-induced hyperlipidemia in rats.

Prolactin (PRL) is a pituitary hormone involved in various physiological processes, including lactation, mammary development, and immune function. To further investigate the in vivo and comparative endocrine roles of PRL, mouse PRL cDNA fused to the cytomegalovirus promoter, was introduced into muscle by direct injection. Previously we studied the function of rat PRL using the same protocol. PRL mRNA was detected in the muscle following injection by RT-PCR and subsequent Southern blot analysis. PRL was also detected and Western blot analysis revealed a relatively high level of serum PRL. In the pCMV-mPRL-injected female mice, the estrous cycle was extended, especially in diestrus stage and the uterus thickening that was shown in normal estrous stage was not observed. In the pCMV-mPRL-injected male mice, new blood vessels were first found at 5 weeks of age and fully developed blood vessels were found after 8 weeks in the testis. The number of Leydig cells increased within the testis and the testosterone level in serum was observed high. Finally, the number of white blood cells (WBCs) increased in the pCMV-mPRL-injected mice. The augmentation of WBCs persisted for at least 20 days after injection. When injection was combined with adrenalectomy, there was an even greater increase in number of WBCs, especially lymphocytes. This increase was returned normal by treatment with dexamethansone. Taken together, our data reveal that intramuscularly expressed mouse PRL influences reproductive functions in female, induces formation of new blood vessels in the testis, and augments WBC numbers. Of notice is that the Leydig cell proliferation with increased testosterone was conspicuously observed in the pCMV-mPRL-injected mice. These results also suggest subtle difference in function of PRL between mouse and rat species.

Purpose: Glyphosate is widely used and its toxic exposures are not rare. Occasionally, glyphosate intoxication can lead to death. The aim of this study is to analyze clinical findings and fatality in glyphosate intoxication. Methods: Clinical data on acute glyphosate intoxication were prospectively collected at 28 hospitals nationwide between August 2005 and July 2006. The patients' clinical symptoms and characteristics of fatalities were investigated and statistical analysis was performed. Results: Among 105 patients who were finally included, gastrointestinal symptoms(59%) were the most common. A significant difference in the amount ingested was observed between patients with higher systolic blood pressure and those with systolic blood pressure less than or equal to 80 mmHg (p<0.001). The more the patients ingested, the more aggravated their mental status became (p=0.004). Seven patients(6.7%) died, and all of them had ingested greater than or equal to 200 ml. Patients who died had ingested greater amounts than the survivors (p<0.001), and their mental status was worse (p<0.001), and systolic blood pressure was lower (p<0.001). According to the result of logistic regression analysis, relative risk was 24.1-fold higher in the 'poor' mental status group compared with 'good'. Conclusion: Patients who ingested large amounts of glyphosate showed poor mental status and lower blood pressure. Statistical difference in amount ingested, mental status, and systolic blood pressure was observed between survivors and patients who died. Ingested amounts and mental status were the most important factor of the prognosis of glyphosate intoxication.

We have developed a direct polymerase chain reaction (PCR) and electrophoresis method for the diagnosis of bovine theileriosis from whole blood DNA analysis without DNA extraction. The technique empolyed a FoLT (formamide, low temp.) technique and was utilized in the diagnosis of bovine theileriosis. Formamide solubilize the blood cells, and the lowered incubation temperatures reduced protein coagulation. 100-200 nL of whole blood and PCR reagents were introduced directly into a PCR tube. After the amplification, the PCR product (816-bp DNA) was introduced into the electrophoresis system. The results of this analysis were consist with those obtained using purified DNA.

Objective The purpose of this case-control study was done to examine the relationship among the acute brain infarction, silent brain infarction and blood lipids. Methods We compared the components of blood lipids among acute brain infarction patients group (n=99), silent brain infarction patients group(n=101) and controls group (n=153). The analysis of the data was done by Frequency Analysis, one-way ANOVA, Post Hoc Test(Duncan), Pearson's Correlation. Results The results were as follows. High density lipoprotein cholesterol(HDL-Chol) was significantly lower in patients of acute brain infarctions group. The blood levels of total cholesterol(T-Chol) was significantly higher in patients of silent brain infarctions. A study on the relationship among the significant variables ; In T-Chol and HDL-Chol, DM(No=0, Yes=1) and Age, they had positive correlation each other. Between Sex(Female=0, Male=1) and HDL-Chol, Age and HDL-Chol, DM and HDL-Chol, they had negative correlation each other. Conclusions These results suggest that low HDL-Chol may be risk factor of acute brain infarction.

Purpose: The aim of this study is to investigate the association between elevated alanine aminotransferase (ALT) and urosepsis in children with acute pyelonephritis (APN). Methods: We retrospectively identified all children who were managed in our hospital with APN during a decade period. In our study a diagnosis of APN was defined as having a positive urine culture and a positive (99m)Tc-dimercaptosuccinic acid scintigraphy. We compared those with elevated ALT and those with normal ALT according to the following variables: age, gender, duration of fever prior to admission, presence of hypotension, C-reactive protein (CRP), creatinine, presence of anemia, white blood cells count, platelet count, blood culture result, and grades of vesicoureteral reflux. In addition, the correlation between elevated ALT and positive blood culture was analyzed in detail. Results: A total of 996 children were diagnosed with APN, of which 883 were included in the study. ALT was elevated in 81 children (9.2%). In the analysis of demographic characteristics, the number of children with elevated ALT was higher in children between 0 to 3 months, boys, and in those with positive blood culture (p=0.002, 0.036, and 0.010, respectively). In multivariate analysis of variables associated with positive blood culture, age younger than 3 months, elevated ALT, elevated CRP, and elevated creatinine showed statistical significance (p=0.004, 0.030, 0.043, and 0.044, respectively). Conclusion: Our study demonstrates the association between elevated ALT and increased prevalence of urosepsis in addition to elevated CRP, elevated creatinine, and age younger than 3 months in children with APN.

Objective : To investigate gamma-Glutamyltransferase (${\gamma}-GTP$) and its related factors in male industrial workers. Method : Five hundred and tony male workers without heart disease, diabetes mellitus, renal disease, hepatitis, and other liver diseases were surveyed in October 1998. Blood samples were collected to test for ${\gamma}-GTP$, total-cholesterol and fasting blood glucose. A self-administered questionnaire survey on life style was also done. Results : The total geometric mean value of ${\gamma}-GTP$ was 30.6 U/L. According to a univariate analysis: age, BMI(body mass index, $kg/m^2$), alcohol consumption, current smoking, stress, diastolic blood pressure, and blood total cholesterol were significantly associated with ${\gamma}-GTP$(p<0.05). From a multiple regression analysis: BMI, alcohol consumption, current smoking, diastolic blood pressure and total-cholesterol were significantly related to ${\gamma}-GTP$(p<0.05). Coffee consumption was negatively related to ${\gamma}-GTP$, but not significantly. Conclusion : We recommend that a change in health behavior (i.e. reducing alcohol intake, controlling BMI and not smoking) is necessary to decrease ${\gamma}-GTP$ in male workers.
