  • The total bacteria count is significantly important factor for hygienic quality in raw milk. BactoScan FMTM and BactoCount IBCTM are the automated instruments for the determination of the total bacterial count in raw milk. They have been used after calibration by standard plate count (SPC) method in South Korea since 2000. It is necessary to re-evaluate for total bacterial counter according to the improvement of milk quality and the change of milk quality grade. Therefore, this study was evaluated the conversion mode of the two machines by SPC method. We collected 921 bulk-tank milk samples throughout the concentration range of 1,000~1,000,000 CFU/mL from June 2020 to October 2021. As a result, when compared by the SPC value, there was a slight difference in total bacterial count in BactoScan below 10,000 CFU/mL and above 200,000 CFU/mL and in BactoCount above 100,000 CFU/mL, respectively. Therefore, the conversion factor for BactoScan and the conversion equation for BactoCount were newly adjusted based on SPC value, and then the correlation coefficients (R2) was 0.85 or higher. In addition, the correlation (R2) between BactoScan and BactoCount was 0.91, which means the results were high positive correlation. These results are expected to contribute to improving the accuracy of the automated instruments for determining of total bacterial count in raw milk.

  • 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.

  • Standard samples were prepared for this study, and applied for BactoScanTM and BactoCountTM in order for quality control evaluation for total bacterial count in raw milk. Accordingly, the preparation of two lots of standard samples for quality control were lyophilized, which contain Lactobacillus lactis. The standard samples were prepared into three different levels of bacterial counts, those were Low 30,000~40,000, Medium 70,000~90,000, High 150,000~220,000 CFU/mL, respectively. Then, the proficiency tests were performed in total 19 laboratories for measuring total bacterial counts. The total bacterial counts in the standard samples showed 37~42, 82~105, 214~240 CFU/mL in the first lot, and it showed 30~36, 67~75, 131~163 CFU/mL in the second lot in low, medium and high levels, respectively. Based on these results, the absolute values of z-scores of six standard samples in 18 laboratories were ≤2, which means the samples are satisfactory. However, z-score in one laboratory was ≤3, which means the sample is questionable. Using two standard samples, the correlation between BactoScanTM and BactoCountTM was 0.9982, which means the results of total bacterial count measurement of both equipment were equivalent. Therefore, the standard samples manufactured in this study for quality control of total bacterial count using BactoScanTM and BactoCountTM in the raw milk could be applied to proficiency tests.

  • The effect of cardiopulmonary bypass on platelet count, platelet function, and bleeding time was studied in 60 patients. Platelet count was significantly reduced during and after cardiopulmonary bypass. Platelet function also had a reduced aggregation response to adenosine diphosphate. Bleeding time was prolonged to over 30 minutes during cardiopulmonary bypass and not returned to normal level until postbypass 1 hour. The amount of postoperative bleeding was proportional to the degree of decrease in platelet count and function, degree of decrease in platelet count and function. There was no significant correlation between duration of cardiopulmonary bypass and platelet count, platelet function, bleeding time, or amount of postoperative bleeding. Patients with cyanotic congenital heart disease showed a larger amount of postoperative bleeding than patients with acyanotic congenital heart disease [P<0.01], and this difference was due to the fact that platelet function was more significantly affected by cardiopulmonary bypass in cyanotic group. Patients using membrane oxygenator showed a less amount of postoperative bleeding than patients using bubble oxygenator [p<0.005] reflecting better preservation of platelet count and function by membrane oxygenator.

  • Objective: Under recognition of the similarity between carbuncle in Oriental medicine and inflammatory disease, NeiShuHuangLianJang(N.H.) has been used as an antiphlogistic agent. The present reports shows the anti-inflammatory effects of N.H. Method: Experimental animals made use of 4-5 weeks age(weight 20-25g) ICR(male)mouse. They were farmed individually in a temperature($22{\pm}0.5{\circ}$) and light(06:00 to 18:00 h) controlled room with free access to water and food. The N.H.(1.0g/kg, 3.0g/kg) extracted from NeiShuHuangLianTang were administered intragastrically prior to LPS I.P injection. we measured WBC count, IL-6 level in plasma and TNF-${\alpha}$ level in plasma. Result : 1. N.H. suppressed inflammatory reaction induced by LPS. 2. N.H. suppressed WBC count in inflammatory reaction induced by LPS. 3. N.H. suppressed 1L-6 level in inflammatory reaction induced by LPS. According to above experiments, N.H. was improved its suppression effect against the inflammatory reaction through WBC count and IL-6 level. So N.H. which is used for the inflammatory disease(carbuncle) in Oriental Medicine is assumed to have a curative effects against this disease by controlling WBC count and IL-6 level in plasma.

  • The cytoplasmic elicitor, nucleotide-binding domain and leucine-rich repeat containing domain receptors (NLRs) is well established molecules in its role in inflammatory response. Among 22 NLR receptors, NOD2 is one of the intensively studied genes of elucidating for the inflammatory bowel disease and Crohn's disease as well. Recent research have accumulated that common genetic mutations in Parkinson's disease (PD) are increasingly related to the susceptibility to Crohn's disease. In this study, with the Korean Genome and Epidemiology Study, we aimed to perform the association between NOD2 polymorphisms and blood cell counts [WBC (white blood cell) count, RBC (red blood cell) count, platelet count], which linked supposedly to cytoplasmic inflammatory responses with clinical specialty. Linear regression analyses were performed, controlling for residential area, sex, and age as covariates. As a results, 12 SNPs from NOD2 gene were significantly associated with WBC counts (Bonferroni correction P-value criteria < 0.05/23=0.00218). In this study, we could ensure an association with NOD2 gene and WBC counts. This is the first report to have relationship between SNPs of NOD2 gene and WBC counts.

  • In recent years, many researches are actively undertaken for environmental-friendly animal production according to the increased understanding about food safety because of the outbreak of various diseases such as mad cow disease, Foot and mouth disease and Poultry Influenza virus. However, high quality(higher safety)- animal production may not be successful without increasing of disease resistance of animal and the improvement of feeding environment. To increase the disease resistance is able to be accomplished by stimulating the immune function. The present study was undertaken to investigate the effects of enzyme mixture reinforced with ${\beta}$-glucanase activity which degrade polysaccharide to release ${\beta}$-glucan known as stimulator of immune function on the change of milk production and somatic cell count. After 12weeks of experimental feeding, milk production tended to be increased and somatic cell count was decreased from average $227{\times}10^4$ to $37.1{\times}10^4$. Milk protein and solid-fat content were tended to increase but milk fat showed decreasing tendency by the feeding of enzyme mixture. All together, it has been suggest6d that the improvement of high quality milk production may be possible through the dietary addition of immune modulating enzyme mixture in lactating dairy cows.

  • Objectives : This study was aimed to evaluate the correlation between changes in disease severity and serum total IgE or eosinophil count in individual patients of atopic dermatitis depending on the change of severity. Methods : We performed a retrospective chart review of 8 cases of atopic dermatitis who underwent blood tests more than five times. Disease severity was assessed by objective SCORing of Atopic Dermatitis index (OSI). Blood tests include serum total IgE, eosinophil counts, aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN) and serum creatinine (SCr). In each subject, on the day that the blood test was performed, OSI was also assesed by a same physician. Correlation between OSI and total IgE or eosinophil count was analysed by nonparametric correlation analysis. Results : There was a statistically significant positive correlation between OSI and total IgE in three cases and a positive correlation between OSI and eosinophil count in two cases. In other three cases, there were no significant correlation. There were no cases that OSI correlated with total IgE and eosinophil count at the same time. In all cases, AST, ALT, BUN and SCr were stable. Conclusions : We suggest that total IgE and eosinophil count may reflect the severity of atopic dermatitis differently in individual patients. We also suggest that total IgE and eosinophil counts may be used as biomarkers to predict the severity of atopic dermatitis in some patients depending on the underlying pathology.

  • Systemic fungicides viz., Bavistin and Beyleton are reported to have curative effect against the infection of Beauveria bassiana in silkworm Bombyx mori L. To understand the influence of the systemic fungicides on the disease suppression/development, hematological studies were carried out. There was an increase in the percent total hemocyte count, granulocyte and plasmatocyte in silkworm treated with the systemic fungicides. It possibly indicates the influence of systemic fungicide on the hemocyte mediated defense system leading to the higher resistance and suppression of disease development.

  • Objectives: Taxi drivers are exposed to various hazards, such as long periods of sedentary work and traffic-related air pollutants. However, studies on the health effects among taxi drivers in South Korea are insufficient. Methods: To assess subclinical hematologic change related to cardiovascular disease among male taxi drivers, we analyzed data from the second Korean National Environmental Health Survey. Fifty-nine taxi drivers and 1,912 controls were included in the analysis. Propensity score matching was performed to adjust for age, body mass index, and urinary cotinine. A total of 295 subjects were matched with 59 taxi drivers. Leukocyte count, platelet count, hematocrit, triglyceride, total cholesterol, HDL cholesterol land total IgE of the taxi drivers were compared with the control groups. Results: Taxi drivers showed significantly elevated blood leukocytes and platelets. Serum total IgE was significantly reduced in taxi drivers. However, blood leukocytes, platelets, and serum total IgE were not significantly correlated with work period among taxi drivers. Conclusions: Regarding the change of the blood leukocyte count, platelet count, and serum total IgE, taxi driving has the possibility to be associated with peripheral inflammation, humoral immunity and cardiovascular risk.
