  • Objectives: To ascertain whether some result of hematological examination could be as reference data for health management of welders. Method: The authors conducted the hematological examination of 1,018 welders and 531 control workers of a shipbuilding industry in Ulsan using automatic blood analyzer. Results: The WBC count of welders was lower than that of control on controlling the age and the duration of employment, but changes of other blood cells were not observed. Conclusion: We could use the results of hematological examination such as WBC counts as an indicator for subtle changes of health status of welders.

  • This study was due to investigate the dietary intakes, serum lipids and other hematological indices in female adolescent smokers. The subjects were 85 smokers, whose average pack-year(smoking years on the basis of one pack of cigarettes per day) was 1.26 and 87 nonsmokers who were female high school students in Seoul. An anthropometric measreument was performed and % body fat was also analyzed by the Bioelectrical Impedance Fatness Analyzer(GIF-891). Dietary intakes and food habits were examined through questionnaires and nutrient intakes were analyzed by the Computer Aided. Nutritional analysis program for professional(CAN-pro). Serum TG, HDL-cholesterol and total-cholesterol levels were measured with test kits. Serum glucose, albumin, GOT and GPT were measured by automated dry chemistry system, SPOTCHEM 4410. Hemoglobin, hematocrit, RBC, WBC and MCV were determined by Semi Automated Microcell Counter(F-520). All data were statistically analyzed by SAS PC package program. There was no significant difference in the anthropometric measurements between smokers and nonsmokers. The caloric intake in adolescent smokers tended to be higher than that of nonsmokers but the difference was not statistically significant. In addition, there was no significant difference between smokers and nonsmokers in biochemical indices. Analysis of serum lipids showed that the serum levels of total-cholesterol and LDL-cholesterol of nonsmokers were unexpectedly significantly higher(p<0.05) than those of smokers. Overall results indicate that smoking itself with short pack-year in healthy female adolescent did not seem to influence apparent health and nutritional status.

  • Automatic hematology analyzers provide the leukocyte differential count and the useful flags of the various hematological parameters. We compared LH 750 (Beckman Coulter Co., Miami, FL, USA) with manual method on differential leukocyte counts and evaluated the usefulness of the suspect flags, provided by this instrument. The comparison of leukocyte differential counts between two methods showed good correlation coefficient (r), which were 0.95 (neutrophil), 0.92 (lymphocyte), 0.82 (monocyte) and 0.95 (eosinophil). The frequency of the total flags displayed on LH 750 were 15.5%, which included immature granulocyte/left shift 63.5%, nucleated RBC 14.6%, platelet clumps 13.1%, variant lymphocyte 50% and blast 16.6%. This instrument showed higher positive predictive value in the flags such as platelet clumps 68.8%, immature granulocyte/left shift 61.5%, nucleated RBC 27.3%, variant lymphocyte 50% and blast 16.7%. In this study, the leukocyte differential counts of LH 750 showed good correlation with manual method and the suspect flags also showed a good performance for applying the criteria of re-examination in the clinical laboratory.

  • Blood tests have been used to develop treatment plans, such as disease diagnosis, treatment effect, and prognosis determination in livestock. The present study examined changes in the blood count, including RBCs, WBCs, and platelets, before and after grazing among the Korean native cattle grazing from spring to autumn. The study compared the blood count of livestock group (A, n=34) that returned from the rangeland to cowshed every evening and livestock group (B, n=21) that were not returned from the rangeland to cowshed every evening during the grazing period. Hematological parameters such as RBC, hemoglobin, hematocrit, MCV, and WBC, neutrophil, eosinophil, monocyte, and lymphocyte were determined using a blood cell analyzer. Livestock group (A) showed significant differences in the values of RBC, MCV, MCHC, WBC, EOS, and LYM. Livestock group (B) showed significant differences in the values of RBC, Hb, HCT, MCV, MCH, PLT, NEU, and BAS. In particular, the RBC count decreased after grazing when compared with that before grazing. Compared with that before grazing, low RBC count was maintained from the first to fifth month of grazing. The WBC count increased from the fourth month of grazing, whereas the EOS count increased from the second month of grazing. These results suggest that the values of RBC and WBC vary before and after grazing, and also with the grazing period. Furthermore, it is necessary to develop a detailed feeding management based on these values of blood analysis for livestock that are raised continuously in the rangeland.

  • The current observational epidemiological study analyzed blood lead levels (BLLs) in occupationally exposed workers from Riyadh region, Saudi Arabia and correlated them with the alterations in the differential cell populations of the WBC panel (lymphocytes [Lym %], mixed [Mid %] cells, and neutrophils [Neu %]). In addition, we examined the effect of confounding factors and their relation to BLLs. BLLs were estimated using the LeadCare II analyzer and hematological parameters using the ADVIA 120 analyser. An inferential analysis was conducted to detect association between the observations and the subjects' clinical characateristics. A total of 132 male subjects were included in the final analyses. Based on CDC guidelines, the subjects were categorized as Group I (BLL <10 ㎍/dL; n=118) or Group II (BLL >10 ㎍/dL; n=14) with average BLLs of 4.4 ㎍/dL and 18.1 ㎍/dL, respectively (p <0.0001). The percentages of Mid cells (p <0.0001) and neutrophils (p=0.048), were significantly altered in subjects with High BLL. A regression analysis indicated that subjects > 50 years of age had significantly higher BLLs (53.2 ㎍/dL) than younger age sub-groups (p <0.0001). Age, education, and profession were significant predictors for lead toxicity. Pb exposure is a major public health issue in Saudi Arabia and calls for further investigations on the cellular and molecular effects on hematological system.

  • Certain amino acids are essential precursors of a variety of important biomolecules in addition to their major function as protein building blocks. ${\delta}$-Aminolevulinic acid (ALA) is synthesized from the condensed form of succinyl-CoA with glycine after decarboxylation catalyzed by ALA synthase. The objective of the study was to determine the effects of ALA supplementation on growth performance, behavioral characteristics and hematological/immune status in nursery pigs. A total of 144 pigs weaned at 21 d of age were allotted to three dietary treatments representing (-) control (w/o antibiotics; NC), (+) control (w/carbadox at 50 mg/kg; PC), and the treatment group with ALA supplementation (0.05%; TA). Each treatment had 6 pens (replicates) with 8 pigs per pen. Pigs were fed phase 1 (21.9% CP, 1.40% Lys) and 2 (20.6% CP, 1.15% Lys) experimental diets for 3 and 2 wks, respectively. Feed intake and weight gain were measured weekly during phase 1 and at the end of phase 2. At the end of phase 2, blood samples were taken and analyzed using an automated hematology analyzer. Skin color and activity of pigs (48 h) from all pens in each treatment were measured at the second week of phase 2. Growth performance was not affected (p>0.05) by the dietary supplementation of ALA during the 5 wk nursery period. Pigs in the TA (6.46) and PC (6.68) had a higher (p<0.05) number of red blood cells ($10^6cell/{\mu}L$) than pigs in the NC (6.15). Pigs in PC (12.16) had a higher (p<0.05) hemoglobin level (g/dL) than pigs in the NC group (11.29) and the TA group (11.47). Pigs in the TA and PC had darker (p<0.05) and less (p<0.05) yellow skin color than pigs in the NC. Pigs in the PC tended (p = 0.081) to be less active than pigs in the other groups. There were no differences in behavioral characteristics between the NC and the TA. The data suggest that ALA supplementation has no adverse effects on growth performance of nursery pigs. Moreover, ALA supplementation increased red blood cell counts which may be beneficial to pigs.
