  • This experiment was carried out to study the responses of cellular component of blood and bone marrow to cold and also the changes of coagulation during cooling. Forty-two mongrel dogs were subjected to hypothermia by ice-water surface cooling technique. Lowest body temperature ranged from 21-23 degree. Dogs were divided into 3 groups,Group I, 12 dogs: pentothal anesthesia for 3 hours, Group II, 20 dogs;hypothermic group and Group III,10 dogs;postsplenectomy hypothermic group. Results were summarized as follows: 1. Hemoglobin, hematocrit and red blood cell count significantly increased when animals were cooled, and increase was noted in similar magnitude among the animals of Group I. 2. White blood cell count extremely decreased after cooling and effect of splenectomy on white blood cell count was not apparent. No significant changes were seen among Group I. 3. Differential count of white blood cell when cooled showed relative increase of polymorphonuclear neutrophil and decrease of lymphocyte. 4. There was marked decrease of platelets when body temperature reached to 21-23degree and essentially. no changes was noted in Group I. 5. Clotting time, bleeding time, plasma prothrombin time, recalcification time, and fibrinolysis showed no significant changes when dogs were cooled. Clot retration and prothrombin consumption during hypothermia appeared to be poor. In Group II, bleeding time decreased after splenctomy and when body temperature was lowered, plasma prothrombin time, clot retraction, and prothrombin consumption decreased. Decreased bleeding time and poor clot retraction were noted in Group I. 6. It was found that megacaryocyte count decreased even though platelet count of peripheral blood markedly diminsished when animals were cooled. There was some tendency of erythroid hyperplasia noted during hypothermia.

  • Investigations for hematologic and biochemical values and the differential count of WBC for Korean indigenous cattle (KIC)is rarely performed. Therefore, when the index of complete blood counts (CBC) and biochemical analysis of KIC was requested, it had many difficulties to make the results for blood condition since the standard hematologic and biochemical values of KIC are lacking. In the present study, we have investigated the hematologic and biochemical values and the differential count of WBC for blood of total 252 KIC and 17 striped cattle (SC) as a control. As a result, the mean values of RBC and platelet of KIC were significantly decreased by age (P<0.05). The mean values of RBC, HCT, MCV and MCHC between KIC and SC of the same age (2 - 3 years) showed the statistical significance (P<0.05). Also, in the WBC of KIC, the mean values were decreased according to the age from $12.8{\times}10^3/{\mu}l$ under 1 year to $8.5{\times}10^3/{\mu}l$ over 5 years. In the differential count of WBC of KIC, it showed generally the rates of 45% lymphocyte and 35% segmented neutrophil. In the biochemical analysis, the mean values of BUN and globulin were significantly increased according to the age (P<0.05). Additionally, in comparative analysis between pregnant and non-pregnant group of KIC, the mean values of Hg and HCT in pregnant group were significantly decreased (P<0.05). In conclusion, data obtained from this study may be valuable as a standard for interpretation of the results in hematologic and biochemical analysis of KIC.

  • Objective: To evaluate the usefulness of serum concentrations of macrophage migration inhibitory factor (MIF) of patients with ovarian cysts for differential diagnosis of endometrioama. Method: From Jan. 2003 to Dec. 2004, preoperative serum MIF levels were assessed in 28 women with endometrioma, 32 with benign epithelial tumor, 23 with functional and simple cysts, 22 with benign mature cystic teratoma, and 25 women without ovarian tumor as control. MIF levels were determined using an ELISA (Quantikine Human MIF immunoassay, R&D Systems, Inc., USA). Results: Mean MIF levels were higher in all groups with benign tumors than control (all p<0.01), but there was no significant difference between benign tumor groups (p=0.95). There was no significant correlation between MIF levels and tumor volume, body mass index (BMI) (p=0.635, 0.674 respectively) Serum MIF level had significant correlation with count of WBC and neutrophils (p=0.008, 0.024 respectively), but had no correlation with count of lymhocytes and monocytes (p=0.688, 0.294 respectively). Conclusions: This study showed a marked increase in MIF concentrations in the peripheral blood of patients with endometrioma, but there was no significant difference with other benign tumors. Serum MIF level had significant correlation with count of WBC and neutrophils. These suggest serum MIF level has no usefulness for differential diagnosis of endometrioma from other benign ovarian cysts.

  • With technological advances in automatic hematology analyzers, primary and screening differential counts of white blood cells (WBC) are done with automatic hematology analyzers. They are using different measurement and analysis principles, so differences in WBC differentials and WBC morphology flag exist. This study was carried out to analyze WBC differential counts and WBC morphology flags comparing them with the manual method. Patient EDTA samples in Vacutainer requested for WBC differentials were analyzed with XE-2100. And those samples with suspect flags messages index over 100 were selected and were analyzed with ADVIA-120. Peripheral blood smear film was subsequently made. Three investigators counted 200 cells each (600 cells) in 111 Wright-Giemsa stained blood films. Between two automatic hematology analyzers, neutrophil, lymphocyte, eosinophil, and monocyte showed good correlations, but basophil had moderate correlation. Among automatic hematology analyzers and manual count, neutrophil, lymphocyte, and eosinophil had good correlations, but monocyte had moderate correlation. XE-2100 had higher monocyte, which was due to atypical lymphocyte and myeloblast. LUC in ADVIA-120 was not due to monocyte in XE-2100. Morphology flagging rates were 146.9% in XE-2100 and was 93.2% in ADVIA-120. Positive predictive values of morphology flag were 58.2% in XE-2100 and 54.4% in ADVIA-120. Flags such as atypical lymphocyte, immature granulocyte, and left shift had higher predictive values and those such as N-RBC, platelets clump, and blast had lower ones. Between automatic hematology analyzers, WBC differentials showed good correlations. Predictive values for morphology flags can be variable with changing criteria. Reviewing criteria for WBC differentials and morphology flags should be established in each laboratory with regards to size of laboratory and patients it serves.

  • A total of fourteen, 1-wk-old male Holstein calves were allotted into two groups consisted of control (CON) and IGY which was orally administrated with immunoglobulin yolk (IgY) for 1wk. Calves in both groups were provided with milk replacer according to feeding program and had ad libitum access to timothy hay for the entire experimental period (7wks). At 0, 7 and 49 day of experiment, blood samples were collected from the jugular vein of calves to investigate blood biochemical profiles and the differential count (%) of white blood cell (WBC). We also monitored growth performance and colony forming unit (CFU) of fecal microbial population in calves. The adminstration of IgY in calves did not affect body weight and weight gain during 49 days feeding trial compared with control group. The CFU of E. coli and Lactobacilli in the feces of calves were not significantly affected by IgY treatment, whereas the score of the calf scours during day 43 to 49 in IgY group showed a significant (P<0.05) solid type. There were no differences in plasma biochemical components including total protein, albumin, immunoglobulin and the other indicators. As for WBC differential count (%), there was no statistical difference in the percentages of neutrophil, lymphocyte, monocyte, eosinophil and basophil at 0, 7 and 49 days after the oral supplementation of IgY. In conclusion, the oral supplementation of IgY as an immunostimulant did not affect growth performance, fecal microbial population, blood biochemical profile and WBC differential count in Holstein calves.

  • 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.

  • The Dexamethasone (DEX) loaded chitosan microspheres were prepared by thermal denaturation and chemical cross-linking method using a dierent concentration of glutaraldehyde as chemical cross-linking agent. The prepared microspheres were evaluated for the percentage of Drug Loading (DL), Encapsulation Efficiency (EE) and surface morphology by Scanning Electron Microscopy (SEM). DL and EE were found to be maximum range of 10.0 to 10.79 % and 58.19 to 64.73 % respectively. The SEM Photographs of the resultant microspheres exhibited fairly smooth surfaces and predominantly spherical in appearance. In addition, Fourier Transform Infrared Spectroscopy (FTIR) and Differential Scanning Calorimetry (DSC) shown that there was no interaction between the drug and polymer. In vitro and in vivo release studies revealed that the release of dexamethasone was sustained and extended up to 63 days and effectively controlled by the extent of cross-linking agent. Non-clinical parameters such as paw volume, hematological parameters like Erythrocyte Sedimentation Rate (ESR), Paced Cell Volume (PCV), Total Leucocytes Count (TLC), Hemoglobin (Hb), Differential Cell Count (DCC) were investigated in Fruend's Complete Adjuvant (FCA) induced arthritic rats. Radiology and histopathological studies were also performed in order to evaluate the therapeutic efficacy of the DEX-loaded microspheres in extenuating the rat arthritic model.

  • Effects of chicken egg white derivatives (EWD and EF-203) on the changes of blood cells and the neutrophil phagocytic activity were examined in the rats. Rats were administered orally with either EWD (200 mg/kg) or EF-203 (200 mg/kg) for 3 days. Thereafter, the changes of blood cell values (RBC, WBC, platelets, PCV, differential count of neutrophils) and the phagocytic activity of neutrophils were evaluated for 7 days. The numbers of WBC and the differential count of neutrophils of rats administered with either EWD or EF-203 were significantly increased (p

  • Anemia can be defined as a reduction in blood hemoglobin concentration or red cell mass relative to age matched normal values. Clinical presentation may range from obviously pale and lethargy to an incidental finding during screening of an otherwise well appearing child. The differential diagnosis of anemia in each instance is broad with numerous possible etiologies. A careful history and physical examination as well as complete blood count, peripheral blood smear and additional laboratory tests are necessary in defining underlying cause of the anemia and guide in further treatment plans. In addition, Iron deficiency anemia and anemia of inflammation are common causes of mild to moderate anemia in children, but most pediatricians have some confusions to differentiate these two entities.

  • Purpose : To assess the efficacy of recombinant human granulocyte-macrophage colony-stimulating factor(GM-CSF) in the neutropenia by radiotherapy. Materials and Methods : Eleven patients with various solid tumor were treated with a daily subcutaneous dose of GM-CSF(3-7microgram/kg) for 5days during the radiotherapy. Before and during the course of the study all the patients were monitored by the recording of physical examination, the complete blood count with differential and reticulocyte count and liver function test. Eight patients received prior or concurrent chemotherapy. Results : In 10 patients, the neutrophilic nadir was significantly elevated and the lenght of time that Patients had a neutrophil count below $10^3/mm^3$ a threshold known to be critical to acquiring infective complications was shortened following GM-CSF injection. A significant rise (two fold or greater) of neutrophil count was seen in 10 of 11 patients. In most patients, discontinuation of GM-CSF resulted in a prompt return of granulocyte counts toward baseline. However the neutrophil count remained elevated over $10^3/mm^3$ during radiation therapy, and radiotherapy delays were avoided. Other peripheral blood components including monocytes and platelets also increased after GM-CSF treatment. No significant toxicity was encountered with subcutaneous GM-CSF treatment. Conclusion : GM-CSF was well tolerated by subcutaneous route and induced improvement in the neutropenia caused by radiotherapy.
