In this paper, we propose an efficient WBC 14-Diff classification which performs using the WBC-ResNet-152, a type of CNN model. The main point of view is to use Super-pixel for the segmentation of the image of WBC, and to use ResNet for the classification of WBC. A total of 136,164 blood image samples (224x224) were grouped for image segmentation, training, training verification, and final test performance analysis. Image segmentation using super-pixels have different number of images for each classes, so weighted average was applied and therefore image segmentation error was low at 7.23%. Using the training data-set for training 50 times, and using soft-max classifier, TPR average of 80.3% for the training set of 8,827 images was achieved. Based on this, using verification data-set of 21,437 images, 14-Diff classification TPR average of normal WBCs were at 93.4% and TPR average of abnormal WBCs were at 83.3%. The result and methodology of this research demonstrates the usefulness of artificial intelligence technology in the blood cell image classification field. WBC-ResNet-152 based morphology approach is shown to be meaningful and worthwhile method. And based on stored medical data, in-depth diagnosis and early detection of curable diseases is expected to improve the quality of treatment.

Characteristics of exhaust from chimney of electricity generator are analyzed based on CFD when Waveguide-Below-Cutoff (WBC) array is installed in order to achieve the certain level of electromagnetic pulse (EMP) shielding. The main purpose is prediction of average and maximum velocity of exhaust. The results reveal that: 1) When the specification of waveguide is given as 80-diameter, 400-length, and the gap of 20 mm, the shielding effectiveness (SE) is 140dB. The average and maximum velocity of exhaust in the chimney with WBC Array can be represented as exponential functions. 2) As the number of WBC increases, the velocity in the chimney dwindles. 3) Under the situation that WBC with 80 mm diameter is located at intervals of 20 mm, the average velocity can be approximated by $25.5344{\times}e^{(-0.0098{\times}N_{WBC})}$ with input velocity of 15 m/s. In addition, the determination coefficient is 0.915, which is sufficiently high.

The cells are concentrated approximately 20-fold by cytocentrifugation. This study evaluated the nucleated cell number for cells recovered on slide by using Cytospin-3 (Thermo Shandon Ltd. UK) and Cytopro-7620 (Wescor Inc., USA) cytocentrifuges to hematocytometer cell count of $0{\sim}5WBCs/{\mu}L$ of hematocytometer in the cerebrospinal fluid cell count. One hundred forty eight samples of $0{\sim}5WBCs/{\mu}L$ on hematocytometer, were cytocentrifuged by Cytospin-3 and Cytopro-7620 instruments. The nucleated cell number for cells recovered on slide was counted after Wright stain. The nucleated cell number for cells recovered on slide was 0~40 cells in the 44 samples of $0WBC/{\mu}L$, and 3~95 cells in the 31 samples of $1WBC/{\mu}L$. It was observed that the nucleated cell number for cells recovered on slide was 13~100 cells in the 44 samples of $2WBCs/{\mu}L$, and more than 100 cells in the 29 samples of $3{\sim}5WBCs/{\mu}L$, respectively. In addition, extremely normal lymphocyte, monocyte and polymorphonuclear neutrophil were observed in the 143 samples of $0{\sim}5WBCs/{\mu}L$. Macrophage and eosinophil were also rarely observed. The nucleated cell number for cells recovered on slide was 20 cells, which were regarded as $1WBC/{\mu}L$ in body fluid cell count. However, in this study, we made alterations to report nucleated cell percentage as 0% without preparing the cytocentrifuged slide at $0WBC/{\mu}L$ by using the cell yield in a comparison between the value of $0{\sim}5WBCs/{\mu}L$ and nucleated cell number for cells recovered on slide.

The values of blood composition were analyzed by age, season, and sex from Chejuhorse in Korea. The results obtained were summarized as follow; 1. The values of white blood cell(WBC), packed cell volume(PCV), mean corpuscular volume (MCV), and mean corpuscular hemoglobin concentration(MCHC) were significantly different between age. The WBC value was decreased with the progress of age and the PCV value was lower in the early age of 1,2 to 3 years than in the higher age of 4 to 5, and over 6 years. 2. The mean value of MCV was increased with the progress of age but the adverse was true in MCHC. 3. In the case of seasons, the values of red blood cell(RBC), WBC, hemoglobin(Hb) PCV, MCV, mean corpuscular hemoglobin(MCH), MCHC, globulin(Glo), albumin/globulin(A/G) ratio, inorganic phosphorus(Pi), cholesterol(Chol), and chlorine(Cl) showed significant differences. The number of RBC was not varied from winter to summer but decreased in autumn. The number of WBC was high in summer and autumn, but low in winter and spring. 4. The values of MCV were high in autumn and winter, but low in spring and summer. 5. The values of MCH and MCHC were similar in spring and summer, but strikingly increased in autumn. 6. The values of Glo and A/G ratio were negatively correlated with the season; The value of A/G ratio was lowest in summer but no differences were observed in spring, autumn and winter. On the other hand, the value of Glo was highest in summer but no differences were observed in spring, autumn, and winter. 7. The values of Pi, Chol, and CI were high in summer and winter, but low in spring and autumn. 8. The values of RBC, MCV, and MCH were significantly different between sex. The value of the RBC count in male was higer than the female, but the adverse is true in MCV, and MCH.

Scopoliae rhizoma is a perennial herb which has a similar effect with atropine on the cardiovascular system. It is also known to have a seditive and anticonvulsant activity on the central nerve system. In order to evaluate an acute toxicity of Scopoliae rhizoma, the present study was performed after administration the Scopoliae rhizoma prepared by both decoctional and frozen dried extract through three different routes (oral; 5,000 mg/kg, intraperitoneal; 2,000 mg/kg, subcutaneous; 5,000 mg/kg) to the female ICR mice. In the group treated intraperitoneally with a frozen dried extract, abnormal clinical signs such as decreased activity, crouch, potosis and abnormal walking were observed for 40 rain after administration. With regard to WBC, decreased number of lymphocyte and increased number of monocyte and granulocyte were also observed in the animals received intraperitoneally with Scopoliae rhizoma extract. Taken together, what toxicity of Scopoliae rhizoma was shown differently depending on its type for administration may be resulted in the differency of administered dose. The results provided here support a pharmacological and toxicological consideration for its clinical use in the regard of oriental medicine.

During an 8 month period from January to August 2007, complete blood count (CBC) samples were taken from various wards and from the outpatient department at Samsung Medical Center. In order to determine whether or not the total white blood cells were over counted, results were obtained from both the 4Diff/channel and the white blood cell channel from the automated blood analysis equipment from S company for comparison. Among patients who were on long term treatments, the number of cases determined to be over counted by comparing the WBC counts during this 8 month period was 25. Clinical chemistry tests were also conducted on the same day on the 25 samples taken. 68% of the patients showed to exceed normal range of aspartate transaminase (AST) and alanine aminotransferase (ALT) indicating abnormal liver function, and the total bilirubin range were also in excess in 60% of the total samples taken. Further clinical information which was obtained from the patients showed 98% of the patients were administered with cefepime which is the 4th generation cephalosporin at the time when the WEC were over counted. It is assumed that a multiple of factors investigated caused the over count of the WEC rather than a single factor.

Objectives: This study was performed to investigate the associations between the metabolic syndrome (MetS) and inflammatory markers. Methods: This cross-sectional analysis was performed using data from 1578 Koreans aged 40-69 years residing in a rural area. We investigated associations between MetS and circulating high sensitivity C-reactive protein (hs-CRP), white blood cells (WBC) and adiponectin. MetS was defined using the criteria proposed by the National Cholesterol Education Program Adult Treatment Panel III (ATP-III). Results: Increased WBC counts and hs-CRP levels and decreased adiponectin levels were observed in subjects with MetS. WBC, hs-CRP and adiponectin levels linearly deteriorated with an increase in the number of MetS components (all ptrend <0.005). Finally, adjusted odds ratios (ORs) for the risk of MetS by increase/decrease in 3 inflammatory markers were calculated by multivariate logistic regression analyses. In terms of changes in inflammation markers, in men, the adjusted ORs (95% confidence interval) were 1.15 (1.01-1.31) for WBC, 1.64 (1.02-2.64) for hs-CRP, and 0.19(0.08-0.45) for adiponectin, whereas corresponding adjusted ORs (95% Cls) in women were 1.27 (1.15-1.40), 0.98 (0.67-1.42), 0.09 (0.04-0.18), respectively. Conclusions: Serum adiponectin levels and WBC counts were found to be strongly associated with MetS in both sexes. However, hs-CRP lost its significance after adjusting for BMI and other inflammatory markers in women. This study shows that inflammatory response is associated with MetS in the Korean population. Further prospective studies are necessary to confirm the contribution made by inflammatory markers to the development of MetS.
