The purpose of the present study was to investigate changes in hematological and serum biochemical parameters in ponies exercising 3 times a day. The study included 10 healthy 4- to 5-year-old Jeju crossbred ponies used in riding lessons at an equestrian riding school. Hematology and serum chemistry samples were obtained before the initial lesson and after the last lesson of the day. The post-exercise results showed that packed cell volume, white blood cell, red blood cell, hemoglobin, and total protein levels increased significantly (p < 0.05). Serum Na⁺ also increased significantly (p < 0.01), but serum Ca⁺⁺ decreased significantly (p < 0.01). Creatinine kinase, aspartate amino transferase, gamma glutamyl transferase, blood urea nitrogen, creatinine, and bilirubin levels increased significantly (p < 0.05), but the glucose level decreased significantly (p < 0.05). Furthermore, the serum cortisol hormone level increased significantly (p < 0.01). The results suggest that participating in riding lessons three times a day may result in various physiological changes, indicating the presence of exercise-related stress in riding ponies.

Oxidative stress caused by elevated reactive oxygen species (ROS) in the heart causes various heart diseases. Oxidative stress is known as a factor that causes diseases in various organs as well as the heart. Diseases such as heart failure, myocardial infarction, and cardiomyopathy caused by oxidative stress in the heart can be treated with medication or surgery. Recently, blood cells concentrate (BCC) is used in various treatment areas such as orthopedics, gynecology, and urology. BCC therapy is applied to treatment by concentrating platelets and white blood cells necessary for regeneration through simple centrifugation using autologous blood. As the platelets are activated, many growth factors are released from alpha granules of the platelets. Growth factors such as TGF-β1, PDGF, VEGF, and EGF derived from platelets are involved in various cell signaling pathway. Due to these growth factors, BCC can contribute to tissue regeneration and can treat various diseases. CD34+ cells contained in BCC may also play an important role in tissue regeneration. In this study, we investigated whether BCC has a regenerative effect on heart disease, and if so, what mechanism causes the effect. To observe this, cardiomyocyte cells were treated with H₂O₂ to induce oxidative stress. And the effect was confirmed in the presence or absence of BCC. As a result, in the presence of BCC, the oxidative stress of cardiomyocyte cells was reduced and cell damage was also reduced. These results suggest that BCC therapy can be a new treatment alternative for heart disease.

Leukemia is a malignancy caused by precursor cells of white blood cell. It is a malignant tumor of hematopoietic organs, characterized by the disorder of hematopoietic function due to the proliferation of immature bone marrow cells or lymphatic cells and by abnormal tissue infiltration of leukemic cells. The major signs of leukemia are caused by the failure of bone marrow function. As the number of red blood cells decreases, anemia is to appear. The number of white blood cells in leukemia is usually increased but immature white blood cells circulating the body has little defense ability, thus become susceptible to infection. 27 year-old female patient who was treated chemotherapy and bone marrow transplantation after diagnosed as chronic myelogenous leukemia(CML) was diagnosed as osteomyelitis in mandible after clinical and dental radiographic film examination. Because of the result of examination, the involved tooth of the patient was extracted accompanied by sequestrectomy and saucerization under general anesthesia. After the patient had long term medication of antibiotics, the lesion was healed. Therefore. author, et al. report this case with literature review.

Background: An easy, reproducible and simple marker is needed to estimate phase of endometrial pathologic lesions such as hyperplasia and endometrial cancer and distinguish from pathologically normal results. We here aimed to clarify associations among neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), endometrial hyperplasia and cancer in patients with abnormal uterine bleeding. Materials and Methods: Patients (n=161) who were admitted with abnormal uterine bleeding and the presence of endometrial cells on cervical cytology or thick endometrium were investigated. The study constituted of three groups according to pathologic diagnosis. Group 1 included endometrial precancerous lesions like hyperplasia (n=63), group 2 included endometrial cancerous lesions (n=38) and group 3 was a pathologically normal group (n=60). Blood samples were obtained just before the curettage procedure and the NLR was defined as the absolute neutrophil count divided by the absolute lymphocyte count; similarly, PLR was defined as the absolute platelet count divided by the absolute lymphocyte count. Results: The white blood cell count was significantly higher in patients with cancer than in those with hyperplasia (p=0.005). The platelet count and neutrophil to lymphocyte ratio were significantly higher in patients with cancer than in control patients, but there was significantly no difference between patients with hyperplasia and other groups (p=0.001 and p=0.025 respectively). PLR was significantly lower in control subjects than in other groups (p<0.001), but there was no significant difference between patients with hyperplasia and those with cancer. Conclusions: PLR was significantly lower in control subjects than in other groups. Thus both hyperplasia and cancer may be differentiated from pathologically normal patients by using PLR. White blood cell count was significantly higher in patients with cancer than in those with hyperplasia and pathologically normal patients. Therefore white blood cell count may be used for discriminate hyperplasia to cancer. By using multiple inflammation parameters, discrimination may be possible among endometrial cancer, endometrial precancerous lesions and pathologically normal patients.

Objective : C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) are often utilized to evaluate for postoperative infection. Abnormal values may be detected after surgery even in case of non-infection because of muscle injury, transfusion, which disturbed prompt perioperative management. The purpose of this study was to evaluate and compare the perioperative CRP, ESR, and white blood cell (WBC) counts after spine surgery, which was proved to be non-infection. Methods : Twenty patients of lumbar open discectomy (LOD) and 20 patients of posterior lumbar interbody fusion (PLIF) were enrolled in this study. Preoperative and postoperative prophylactic antibiotics were administered routinely for 7 days. Blood samples were obtained one day before surgery and postoperative day (POD) 1, POD3, and POD7. Using repeated measures ANOVA, changes in effect measures over time and between groups over time were assessed. All data analysis was conducted using SAS v.9.1. Results : Changes in CRP, within treatment groups over time and between treatment groups over time were both statistically significant F(3,120)=5.05, p=0.003 and F(1,39)=7.46, p=0.01, respectively. Most dramatic changes were decreases in the LOD group on POD3 and POD7. Changes in ESR, within treatment groups over time and between treatment groups over time were also found to be statistically significant, F(3,120)=6.67, p=0.0003 and F(1,39)=3.99, p=0.01, respectively. Changes in WBC values also were be statistically significant within groups over time, F(3,120)=40.52, p<0.001, however, no significant difference was found in between groups WBC levels over time, F(1,39)=0.02, p=0.89. Conclusion : We found that, dramatic decrease of CRP was detected on POD3 and POD7 in LOD group of non-infection and dramatic increase of ESR on POD3 and POD7 in PLIF group of non-infection. We also assumed that CRP would be more effective and sensitive parameter especially in LOD than PLIF for early detection of infectious complications. Awareness of the typical pattern of CRP, ESR, and WBC may help to evaluate the early postoperative course.

This study attempted to concider the morphological change of red blood cells after whole body irradiation. Blood samples used red blood cells of white mice and mouse after irradiation. Transmission electron microscope observation results, Anisocytosis was observed in red blood cells 20 days after 5 Gy irradiation. Triangle and tetrapod were observed for small red blood cell types. Poikilocytosis, sickle-shaped Drepanocyte, and Acantocyte were observed in general-sized red blood cells. Schizocyte was observed in red blood cells 20 days after 7 Gy irradiation. Scanning electron microscope observation results, Dacryocyte was observed with microcytes. It was also confirmed that red blood cells were get tangled with each other. In addition, polygonal shapes and half-moon shapes were also observed. In conclusion, it is judged that the modified form of pathological study is more important than the numerical change in the study of red blood cells by radiation exposure. In conclusion, it was confirmed that modified morphological studies are more important than numerical changes in the study of red blood cells by radiation exposure.

This experiment was conducted to investigate the effects of pig skin collagen supplementation on growth performance, organ weight, blood characteristics, and intestinal microbiota in broilers. A total of 50 Ross 308 broilers were used for 2 weeks. The five dietary treatments were as follows: NC) basal diet, PC) NC + fish collagen powder 0.1%, T1) NC + pig skin collagen 0.1%, T2) NC + pig skin collagen 0.5%, and T3) NC + pig skin collagen 1.0%. The body weight gain (BWG), feed intake (FI), and feed conversion ratio (FCR) were not affected (p > 0.05) by the dietary treatments in this experiment. Additionally, there were no significant differences (p > 0.05) in the organ weights among the treatments. Broilers fed T1, T2 and T3 diets had higher (p < 0.05) white blood cell (WBC) counts than the broilers fed the NC and PC diets. The Lactobacillus counts in the excreta were improved (p < 0.05) in the broilers fed the T1 and T2 diets. Moreover, the Salmonella counts in the excreta were decreased (p < 0.05) in the broilers fed the PC and T1 diets. In conclusion, supplementation of pig skin collagen in diets improved the white blood cells (WBCs) in the blood and Lactobacillus counts in the excreta, and reduced the Salmonella counts in the excreta. However, when pig skin collagen was increased in the diets, there were no significant differences (p > 0.05). Therefore, the addition of 0.1% pig skin collagen in the feed provided beneficial effects on the blood characteristics and the intestinal microbiota environment.

In order to obtain basic data concerning the treatment of canine demodicosis, 8 Doberman Pinschers were infected with Demodex canis. The clinical signs, were examined after infection, and their hematological and blood chemical values were determined, along with four non-infected control dogs of same breed. The number of white blood cells, especially the number of band neutrophils was significantly higher(p<0.01) in the infected than in the non-infected control dogs. This result indicated that the first episode of secondary infection should be treated with an appropriate antibiotics based on the culture and sensitivity test. The red blood cell counts, packed cell volume, hemoglobin contents, and serum albumin levels were significantly lower (p<0.01~0.001) in the infected than in the non-infected control dogs. These results suggested that the infected dogs had an anemia due to malnutrition. Thus, the infected dogs should be on a well balanced, high protein diet.

In this study, Kami-honghwa-tang (KH-19) was designed and animal study was conducted to evaluate its efficacy on the reduction of the side effect of radiotherapy. Bone marrow toxicity is one of the major side effect of radiotherapy which cause the reduction of blood cells, and KH-19 was designed to protect and enforce blood. C57BL/6 mice were irradiated with 4 Gy of gamma ray, and divided into control group which was treated with water and KH-19 group which was treated with 1.5g/Kg of KH-19 up to 4 weeks. KH-19 group showed significantly increased white blood cells, lymphocytes and platelet count compared with control group (p<0.05). When bone marrows were examined, KH-19 group showed higher cell densities than control group (p=0.06). KH-19 may increase blood cell count after radiation by its protective effects on bone marrow.
