  • 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.

  • Classification of different blood cell types is an essential task for human's medical treatment. The white blood cells have different types of cells. Counting total White Blood Cells (WBC) and differential of the WBC types are required by the physicians to diagnose the disease correctly. This paper used transfer learning methods to the pre-trained deep learning models to classify different WBCs. The best pre-trained model was Inception ResNetV2 with Adam optimizer that produced classification accuracy of 98.4% for the dataset comprising four types of WBCs.

  • Prolactin (PRL) is a pituitary hormone involved in various physiological processes, including lactation, mammary development, and immune function. To further investigate the in vivo and comparative endocrine roles of PRL, mouse PRL cDNA fused to the cytomegalovirus promoter, was introduced into muscle by direct injection. Previously we studied the function of rat PRL using the same protocol. PRL mRNA was detected in the muscle following injection by RT-PCR and subsequent Southern blot analysis. PRL was also detected and Western blot analysis revealed a relatively high level of serum PRL. In the pCMV-mPRL-injected female mice, the estrous cycle was extended, especially in diestrus stage and the uterus thickening that was shown in normal estrous stage was not observed. In the pCMV-mPRL-injected male mice, new blood vessels were first found at 5 weeks of age and fully developed blood vessels were found after 8 weeks in the testis. The number of Leydig cells increased within the testis and the testosterone level in serum was observed high. Finally, the number of white blood cells (WBCs) increased in the pCMV-mPRL-injected mice. The augmentation of WBCs persisted for at least 20 days after injection. When injection was combined with adrenalectomy, there was an even greater increase in number of WBCs, especially lymphocytes. This increase was returned normal by treatment with dexamethansone. Taken together, our data reveal that intramuscularly expressed mouse PRL influences reproductive functions in female, induces formation of new blood vessels in the testis, and augments WBC numbers. Of notice is that the Leydig cell proliferation with increased testosterone was conspicuously observed in the pCMV-mPRL-injected mice. These results also suggest subtle difference in function of PRL between mouse and rat species.

  • This study was done to establish a mouse model for catheter-related biofilm infection suitable to bioluminescence imaging (BLI). Biofilm formation of Pseudomonas aeruginosa (P. aeruginosa) Xen5 grown on catheter disks in vitro and in an implanted mouse model was real-time monitored during a 7-day study period using BLI. The numbers of integrated brightness (IB) and viable bacterial count (VBC) in the biofilm disks in vitro were highest at 24 h after inoculation; the IB of biofilm in vivo was increased until 24 h after implantation. A statistical correlation was observed between IB and VBC in vitro by linear regression analysis. The actual VBC value in vivo can be estimated accurately by IB without sacrifice. In addition, we monitored the change in white blood cells (WBCs) during infection. The number of WBCs on day 7 was significantly higher in the infection group than in the control group. This study indicates that BLI is a simple, fast, and sensitive method to measure catheter biofilm infection in mice.

  • Purpose: To investigate the effect of infant massage on stress, immune function and self-confidence in postpartum mothers. Method: From September, 2003 to February, 2004, 65 women who had delivered babies and were enrolled in the postpartum clinic were assigned to the experimental group or control group. In the experimental group, infant massage was given for 20 minute sessions twice a day from 4 days to 14 days after delivery. The instruments were Parental Stress Index, serum cortisol levels, WBCs, lymphocytes, and Self Confidence Scale. Results: Stress scores, WBCs and lymphocytes showed significant differences by the time, but there weren't significant differences according to the group and interactions between the group and the time. Cortisol and self-confidence scores showed significant differences by the time and the group. Conclusions: Applying massage to their newborn baby influenced cortisol levels of postpartum mothers. Therefore stress, cortisol, and immune functions in postpartum mothers should be generally screened and follow up studies are needed for the effective application of massage in postpartum mothers.

  • In this paper, we propose an efficient WBC 14-Diff classification which performs using the WBC-ResNet-152, a type of CNN model. The main point of view is to use Super-pixel for the segmentation of the image of WBC, and to use ResNet for the classification of WBC. A total of 136,164 blood image samples (224x224) were grouped for image segmentation, training, training verification, and final test performance analysis. Image segmentation using super-pixels have different number of images for each classes, so weighted average was applied and therefore image segmentation error was low at 7.23%. Using the training data-set for training 50 times, and using soft-max classifier, TPR average of 80.3% for the training set of 8,827 images was achieved. Based on this, using verification data-set of 21,437 images, 14-Diff classification TPR average of normal WBCs were at 93.4% and TPR average of abnormal WBCs were at 83.3%. The result and methodology of this research demonstrates the usefulness of artificial intelligence technology in the blood cell image classification field. WBC-ResNet-152 based morphology approach is shown to be meaningful and worthwhile method. And based on stored medical data, in-depth diagnosis and early detection of curable diseases is expected to improve the quality of treatment.

  • Objective: Skin tumors are the most commonly seen cancer type worldwide. Regarding pathogenesis, it is thought that disruption of kinetics through T lymphocyte-mediated development of chronic inflammation may be involved. The present study was intended to identify role of inflammatory cells such as neutrophils, monocytes and lymphocytes in the determination of risk for skin cancer. Materials and Methods: We retrospectively reviewed charts of 569 cases diagnosed as having primary skin tumors. Data regarding age, gender and histopathological subtype were recorded. Blood parameters studied on the day before surgery including WBCs, neutrophils, and lymphocyte counts, neutrophil:lymphocyte and neutrophil:monocyte ratios were also recorded. Two-hundred and two healthy individuals presented for check-up in an outpatient clinic were selected as the control group. Parameters studied in cases with skin cancer were compared to those healthy individuals. Findings: Of the cases with skin cancer, 401 were basal cell carcinoma (BCC) while 144 were squamous cell carcinoma (SCC) and 13 were malignant melanoma (MM). WBC, neutrophil and monocyte counts and the neutrophil:lymphocyte ratio were found to be lower in the patient group than in the healthy control group (p<0.001) while no significant difference was found in other parameters reviewed (p>0.05). No significant difference was found in WBC, neutrophil, neutrophil: monocyte ratio according to gender (p>0.05). Monocyte count was found to be $0.68{\pm}0.61$ in men and $0.55{\pm}0.25$ in women, indicating strong statistical significance (p<0.001). WBC, neutrophil and monocyte values were highest in control group while lowest in BCC. When BCC and SCC groups were compared to controls, significant differences found (p<0.001). There were no significant differences in lymphocyte counts among groups (p=0.976). Neutrophil:lymphocyte ratios were 3.24 in BCC, 3.59 in SCC, 3.44 in MM and 5.06 in control group (p<0.001). Conclusions: In our study, it was found that there were significant differences in complete blood count, neutrophil, monocyte and neutrophil:lymphocyte levels among groups. Neutrophil: lymphocyte ratio was found to be lowest in BCC among skin cancers.
