The objective of this study was to determine the relationship between udder and teat characteristics and somatic cell count (SCC). A total of 749 (73.1%) milk samples from 1,024 quarters of 259 Holstein cows contained less than 200,000 somatic cells/ml, while 132 (12.9%) quarters contained more than 500,000 somatic cells/ml. Prior to data analysis, somatic cell counts were transformed to natural logarithm. The mean SCS {$log_e(SCS/10^3)$} of milk samples from the front quarters was lower than milk samples from the rear quarters. The highest SCS was observed from cows with the step-shaped udder and the pear-shaped teats, respectively. Increased SCS was observed from cows with large teat diameter, short teat length, short distance between the teat tip to floor (p<0.05) and with increase in parity, respectively.

Since goat milk infant formula has been increased, it is expected that goat milk consumption would be increased. This review summarizes the characteristics of goat milk especially, milk fat, somatic cell count, and goaty flavor. Average milk fat content for one year of twelve goat milk farms was 3.6%, but $2.9{\sim}3.1%$ in summer, which means summer goat milk could not meet the 'Processing and Ingredient Standard for Animal Products'. More than 3.2% for goat milk fat content in 'Processing and Ingredient Standard for Animal Products' should be amended. In addition to, hygienic standard for goat milk should be newly established because goat milk has naturally higher somatic cell count with noninfectious factors. It is thought that 6-trans nonenal and some branched fatty acids are responsible for the goaty flavor. It is necessary to minimize goaty flavor from farm to table because goaty flavor is the most important factor for the promotion of goat milk industry.

The aim of this study was to investigate the effects of production systems and milk collection periods on the somatic cell count (SCC), some microbiological properties, total aerobic mesophilic bacteria (TAMB), coliform, Staphylococcus aureus (S. aureus), yeast and mould) and antibiotic residue of milk; in Turkey. Milk samples were collected from 9 conventional farms and 9 organic farms during one year time, at six different months (December 2013 to October 2014), and all farms were selected from the same geographical locations. All organically managed farms had organic production certificates given by the Republic of Turkey Ministry of Food, Agriculture and Livestock. The count of TAMB, coliform, and coagulase positive S. aureus were affected by production systems at the level of p<0.01; yeast and mold, and somatic cell count (SCC) were affected at the level of p<0.05. But, differences according to months were statistically significant only on TAMB (p<0.01) and coliform (p<0.05) counts. The general means of TAMB, coliform and yeast and mould counts of the organic milk (OM) were significantly lower (p<0.05), while the general means of SCC and coagulase positive S. aureus count of the OM was significantly higher (p<0.05) compared to conventional milk (CM). Antibiotic residue was determined in one of the CM sample and in two of the OM samples. Our study is the first research that compared conventional and organic milk in Turkey. This study indicated that the microbiological quality of OM was the higher in terms of TAMB, coliform and yeast and mould, whereas was the lower in relation to SCC and coagulase positive S. aureus counts. But, the quality of both milk types should be improved.

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.

Pure red cell aplasia is unusual cause of anemia and a selective aplastic disorder that affects the erythroid series of the bone marrow. Fifty percent of all patients with red cell aplasia will have a thymoma. Twenty-five to 30% of those who undergo thymectomy will be cured. A 57-years-old man was admitted to the medical department of Korea University hospital with complaints. Physical examination reveals a sick looking man with a pale lip, anemic conjunctiva and subicteric sclera. On auscultation, coarse breathing sound and moist rale was heard on the right lung field. Neither the liver nor spleen was palpable. A blood count showed the erythrocytes to number 2,640,000/mm3 and hemoglobin to be 7.0gm/dl. A white blood cell count was 5,000/mm3 and a platelet count was 328,000/mm3 Reticulocyte count was 0.7%. Examination of the peripheral blood smear showed the red cell, to be normocytic and normochromic. Urine sugar was three positive and GTT was positive. The anterior-posterior and lateral view of Chest X-ray was suggestive of an anterior mediastinal mass. A bone marrow biopsy reveals absence of red cell precursors and a normal myeloid series and megakaryocytes. At thoracotomy in May 1980 an encapsulated, lobulated, benign thymoma, which measured 5x7x5 cm was removed, microscopic examination showed it was of the spindle cell type. The postoperative course was uneventful, but the patient never had a return of hemoglobin to the blood. The patient was discharged on the postoperative] 3 days. At postoperative 1 month, the patient was readmitted for bone marrow study and had no return of red cells to bone marrow. At now, patient has been treated with steroid and the further follow up study will be needed.

Background: Chronic obstructive pulmonary disease (COPD), is a chronic inflammatory disorder. We evaluated whether white blood cell (WBC) count, is associated with the severity of COPD, independent of other inflammatory conditions, such as metabolic syndrome. Methods: The WBC counts were compared between 1227 COPD patients and 8679 non-COPD adults older than 40. The relationships between the WBC count, lung function, and symptoms score in COPD patients, were determined, using general linear regression analyses. Results: The WBC count was negatively associated with forced vital capacity (FVC, L), FVC (% predicted), forced expiry volume in one second ($FEV_1$, L), and $FEV_1$ (% predicted) in COPD patients. Additionally, the WBC count was independently associated with the quality of life measure, by EQ5D-index score. However, this relationship between WBC count, and disease severity, was not significant in current smokers, because of the confounding effect of smoking, on the WBC count. Conclusion: The WBC count is associated with current smoking status and COPD severity, and a risk factor for poor lung function, and quality of life, especially in non-currently smoking COPD patients. The WBC count can be used, as an easily measurable COPD biomarker.

Jeju Eoseungsaeng lake which is a main water resource of Eoseungsaeng water treatment plant($Q=15,000m^3/d$) experienced high chromaticity(40 CU) and pH(9.46) in 2013. This could decline customer's confidence on drinking water quality unless proper identification and removal of chromaticity were implemented. To find cause of chromaticity, water monitoring on various water parameters including TOC, algal cell count, Chl-a, turbidity, SS, conductivity, etc. were implemented. Iron and manganese were excluded from the cause of chromaticity due to its low concentration (i.e., < 0.02 mg/L). Correlation among water parameters showed that relationship between algal cell count and chromaticity was the highest(R=0.43), which suggested that presumably the main reason of chromaticity occurrence in Jeju Eoseungsaeng lake was algae.

Background: Sampling a healthy reference population to generate reference intervals (RIs) for complete blood count (CBC) parameters is not common for pediatric and geriatric ages. We established age- and sex-specific RIs for CBC parameters across pediatric, adult, and geriatric ages using secondary data, evaluating patterns of changes in CBC parameters. Methods: The reference population comprised 804,623 health examinees (66,611 aged 3-17 years; 564,280 aged 18-59 years; 173,732 aged 60-99 years), and, we excluded 22,766 examinees after outlier testing. The CBC parameters (red blood cell [RBC], white blood cell [WBC], and platelet parameters) from 781,857 examinees were studied. We determined statistically significant partitions of age and sex, and calculated RIs according to the CLSI C28-A3 guidelines. Results: RBC parameters increased with age until adulthood and decreased with age in males, but increased before puberty and then decreased with age in females. WBC and platelet counts were the highest in early childhood and decreased with age. Sex differences in each age group were noted: WBC count was higher in males than in females during adulthood, but platelet count was higher in females than in males from puberty onwards (P <0.001). Neutrophil count was the lowest in early childhood and increased with age. Lymphocyte count decreased with age after peaking in early childhood. Eosinophil count was the highest in childhood and higher in males than in females. Monocyte count was higher in males than in females (P <0.001). Conclusions: We provide comprehensive age- and sex-specific RIs for CBC parameters, which show dynamic changes with both age and sex.

The objective of this study was to assess the association of polymorphisms in ${\kappa}$-cn, ${\beta}$-lg, ${\beta}$-lg 5′ flanking region, CSN1S2, and IGFBP-3 genes with milk production traits and mastitis-related traits in Chinese Holstein. Traits analyzed were 305 day standard milk yield, protein percentage, fat percentage, the ratio of fat percentage and protein percentage, pre-somatic cell count, somatic cell count, and somatic cell score, respectively. CSN1S2 locus was uninformative because only one genotype BB was found in Chinese Holstein. Allele frequencies of A and B in IGFBP-3 gene were 0.5738 and 0.4262 in Chinese Holstein population, which was different from reported Qinchuan cattle population. The genotypes of animals at IGFBP-3 locus significantly affected 305 day standard milk yield, protein percentage, and somatic cell score. The ${\beta}$-lg genotypes had a significant effect on protein percentage and the ratio of fat percentage and protein percentage. Polymorphism in ${\beta}$-lg 5′ flanking region was associated with 305 day standard milk yield, protein percentage, fat percentage, pre-somatic cell count, and somatic cell count. No significant associations of the polymorphism in ${\kappa}$-cn gene were observed for any trait.

Objective : Here, we evaluated whether cerebrospinal fluid (CSF) profiles and their changes after intraventricular chemotherapy for leptomeningeal carcinomatosis (LMC) could predict the treatment response or be prognostic for patient overall survival (OS) along with clinical factors. Methods : Paired 1) pretreatment lumbar, 2) pretreatment ventricular, and 3) posttreatment ventricular samples and their CSF profiles were collected retrospectively from 148 LMC patients who received Ommaya reservoir installation and intraventricular chemotherapy. CSF profile changes were assessed by calculating the differences between posttreatment and pretreatment samples from the same ventricular compartment. CSF cell counts were further differentiated into total and other based on clinical laboratory reports. Results : For the treatment response, a decreased CSF 'total' cell count tended to be associated with a 'controlled' increase in intracranial pressure (ICP) (p=0.059), but other profile changes were not associated with either the control of increased ICP or the cytology response. Among the pretreatment CSF profiles, lumbar protein level and ventricular cell count were significantly correlated with OS in univariable analysis, but they were not significant in multi-variable analysis. Among CSF profile changes, a decrease in 'other' cell count showed worse OS than 'no change' or increased groups (p=0.001). The cytological response was significant for OS, but the hazard ratio of partial remission was paradoxically higher than that of 'no response'. Conclusion : A decrease in other cell count of CSF after intraventricular chemotherapy was associated with poor OS in LMC patients. We suggest that more specific CSF biomarkers of cancer cell origin are needed.
