General blood tests and leukocyte differential count are very useful in diagnosing, treating and managing patient’s diseases. This study was conducted to reduce errors caused by the manual method as much as possible by using an automated hematology analyzer (Sysmex K-4500), and to alleviate work burden of the laboratory. The T1 and T2 values calculated from leukocyte differential count that was obtained from the automated hematology analyzer Sysmex K-4500, and the results measured from the manual method were compared and analyzed by using the blood samples of 400 patients who were commissioned in the diagnostic laboratory of the hospital with 120 beds. Upon the results of the study, T1 and T2 obtained from lymphocyte differential count of the automated hematology analyzer Sysmex K-4500 demonstrated high correlation compared to manual method, and the analysis of monocyte, eosinophil, basophil and band cell obtained from T1, T2 and manual method enabled percentile calculation, even though it was difficult to predict the exact monocyte, eosinophil, basophil and band cell. Therefore, it is regarded that the optimal patient results can be reported if manual method observation is selectively combined while referring to T1 and T2 obtained from lymphocyte differential count of the automated hematology analyzer Sysmex K-4500.
In this study 300 weaned pigs (Landrace × Yorkshire × Duroc, 23±3 d of age, 5.56± 1.21 kg initial body weight) were used to study the effect of fungal (Aspergillus oryzae, FSP-A) and fungal + bacteria (Aspergillus oryzae + Bacillus subtilis, FSP-B) fermented soya proteins on their blood hematology, enzymes and immune cell populations. Pigs were allotted to 5 treatments, each comprising of 4 pens with 15 pigs. Basal diets consisted of 15% soyabean meal (Control diet) while for treatment diets SBM was replaced with 3 and 6% of each FSP-A and FSP-B, respectively. The experimental diets were fed from 0 to 14 day after weaning and then a common commercial diet was fed from 15 to 35 day. Blood was collected on 14 and 35 day of experiment and analyzed for hematology, aspartate transaminase (AST), alanine transaminase (ALT) and immune cell populations. At d 14, lower RBC count, Hb and HCT values and higher AST values were noted in pigs fed FSP-A diets when compared with Control and FSP-B fed pigs.Also at d 14 pigs fed 6% FSP-A had lower NE (P<0.05) when compared with those fed 6% FSP-B. The level of FSP influenced the RDW on d 14 and MCHC, MO and MPV on d 35. In addition on d 35, pigs fed 3% FSP-A had lesser NE than those fed 6% FSP -A and Control diet, while pigs fed 6% FSP-B had the highest number of MO compared to other treatments. But there were no differences in the plasma AST and ALT values on d 35. Thus it may be concluded that the FSP either by fungal or fungal + bacterial sources had an influence on the blood hematological status and the populations of immune cells.
The present study were performed to analysis the hematocrit and the red blood cells content into the blood plasma of the transgenic pigs harboring recombinent human erythropoietin gene (rhEPO). Mouse whey acidic protein (mWAP) linked to rhEPO gene was microinjected into pronuclei of porcine one-cell zygotes. After delivered of offspring, PCR analyses identified one mWAP-rhEPO transgenic founder offspring(F/sub 0/). The first generation of transgenic pig (F/sub 0/) harboring mWAP-hEPO appeared to be a male, and the second generation (F₁) pigs were made by natural mating of F/sub 0/ with domestic swine, and male and female transgenic pigs (F₁) were identified by PCR. The blood samples from transgenic and normal pigs were collected for 50 days during lactation and were counted the red blood cell (RBC) numbers and Hematocrit (HCT) content into the blood. The transgenic pigs expressing rhEPO in their blood gave rise to higher RBC numbers and HCT contents than control animals. rhEPO was secreted both in the blood and milk of genetically engineered pigs harboring rhEPO gene. Therefore, this study provides a model regarding the production of transgenic pig carrying hEPO transgene for biomedical research.
The greater horseshoe bat (Rhinolophus ferrumequinum) is distributed throughout Europe, Africa, Australia, and South Asia. It habits mainly in the cave in small groups and forming communities in late spring. It has interesting reproductive behavior because it keeps sperm for a few months in female reproductive tracts and then those sperms attend in fertilization. This breeding pattern is a sperm storage type and belongs to Rhinolophidae or Hipposideridae. The greater horseshoe also habits in Korea. However, the reasons of reproductive behaviors has not much uncovered. In this study the characters of ovary and the levels of steroid hormones were investigated from September to November. The histological, ELISA, and immunohistochemical methods were employed. The pre-ovulatory follicle was detected only at October sample. On the other hand, the blood level of testosterone was not detectable but the levels of 17β-estradiol and progesterone were exist within the detectable range. E2 and P4 levels were peak in October. Besides, the key enzymes for estradiol synthesis, CYP17 and CYP19 were localized in the theca layer and granulosa cells, respectively. October is known as mating time in this species. However, progesterone receptors could not detect at this period. Put together, it is suggested that, the increase of estrogen and the absence of progesterone receptors on preovulatory follicle is the cause of the mating without ovulation. The understanding of the expression regulation in this system will be base of the understanding the anovulation in mammals.
