Background: We aimed to determine whether routine second trimester complete blood cell (CBC) count parameters, including neutrophil-lymphocyte ratio (NLR), lymphocyte-monocyte ratio (LMR), and platelet-lymphocyte ratio (PLR), could predict obstetric outcomes. Methods: We included singleton pregnancies for which the 50-g oral glucose tolerance test and CBC were routinely performed between 24 and 28 weeks of gestation in our outpatient clinic from January 2015 to December 2017. The subjects were divided into three groups according to their pregnancy outcomes as follows: group 1, spontaneous preterm births, including preterm labor and preterm premature rupture of membranes; group 2, indicated preterm birth due to maternal, fetal, or placental causes (hypertensive disorder, fetal growth restriction, or placental abruption); and group 3, term deliveries, regardless of the indication of delivery. We compared the CBC parameters using a bivariate correlation test. Results: The study included 356 pregnancies. Twenty-eight subjects were in group 1, 20 in group 2, and 308 in group 3. There were no significant differences between the three groups in neutrophil, monocyte, lymphocyte, and platelet counts. Although there was no significant difference in NLR, LMR, and PLR between the three groups, LMR showed a negative correlation with gestational age at delivery (r =-0.126, p =0.016). Conclusion: We found that a higher LMR in the second trimester was associated with decreased gestational age at delivery. CBC parameters in the second trimester of pregnancy could be used to predict adverse obstetric outcomes.

Complete blood cell count(CBC) is a technique that counts leukocytes for each type of blood cell being analyzed. The principle is that laser is incident to ex vivo flowing leukocytes in a microcapillary tube and scattered light occurs by laser and leukocytes. By collecting the scattered light, we can count the types of cells because different cells generate different light-scattering patterns. However, the technique has an intrinsic limitation, scattering pattern is shown in a wide range region in the resulting, which makes it difficult to accurate analyze and use fluorescent dyes. To overcome this limitation, a new design of CBC with a dual laser, which irradiates with orthogonal angles for collecting quad-scattering information was proposed. Before development, the scattering difference depending on wavelength must be investigated to only catch up to the scattered signal by angles. Some studies, which focused on simple particles, have been conducted to theoretically and experimentally investigate different scatterings by wavelength. In this study, we propose an optical system for measuring scattered light and investigate a complex particle. As a result, the green laser made strong scattering signals in both the forward and side direction: 10% and 30%, respectively.

Background: Cushing syndrome is characterized by glucose intolerance, cardiovascular disease, and an enhanced systemic inflammatory response caused by chronic exposure to excess cortisol. Eosinopenia is frequently observed in patients with adrenal Cushing syndrome, but the relationship between the eosinophil count in peripheral blood and indicators of glucose level in patients with adrenal Cushing syndrome has not been determined. Methods: A retrospective study was undertaken of the clinical and laboratory findings of 40 patients diagnosed with adrenal Cushing syndrome at Chungnam National University Hospital from January 2006 to December 2016. Clinical characteristics, complete blood cell counts with white blood cell differential, measures of their endocrine function, description of imaging studies, and pathologic findings were obtained from their medical records. Results: Eosinophil composition and count were restored by surgical treatment of all of the patients with adrenal Cushing disease. The eosinophil count was inversely correlated with serum and urine cortisol, glycated hemoglobin, and inflammatory markers in the patients with adrenal Cushing syndrome. Conclusion: Smaller eosinophil populations in patients with adrenal Cushing syndrome tend to be correlated with higher levels of blood sugar and glycated hemoglobin. This study suggests that peripheral blood eosinophil composition or count may be associated with serum glucose levels in patients with adrenal Cushing syndrome.

Objective : The aim of this study is to investigate the inhibitory effect of Injinchunggantang on hepatic sclerosis induced by $CCl_4$. Methods : Weight, liver function test and complete blood cell count, gross findings, and findings on liver tissue of the past(Hematoxylin & Eosin stain, Masson-Trichrome stain) were studied. Results : When it comes to the change of rats' body weight, The $CCl_{4^+}$Injinchunggantang group lost far less weight than The $CCl_{4^-}$only group. In the liver function test, which is focused on various areas such as total cholesterol, alkaline phosphotase, albumin, aspartate transaminase, alanine transaminase, The $CCl_{4^+}$Injinchunggantang group was much more closer to normal limit than the $CCl_4$ only group. In the complete blood cell count, including white blood cell, red blood cell, hemoglobin, hematocrite, platelet, The $CCl_{4^+}$Injinchunggantang group significantly closer to normal limit than $CCl_{4^-}$only group. In the gross findings of hepatic fibrosis models, Injinchunggantang showed inhibitory effect on hepatic fibrosis in the order. In the past findings of hepatic fibrosis models in Hematoxylin & Eosin, Masson-Trichrome staining, the liver in $CCl_{4^-}$only group showed atrophy and necrotic change with white nodules, whereas that of $CCl_{4^+}$Injinchunggantang group showed lesser significant change with the well_preserved tone of the tissue. In the extent of the inhibition of the hepatic fibrosis, the Injinchunggantang group showed statistically significant inhibitory effect(p<0.05) in the sclerosis model. Conclusions : These results show that Injinchunggantang have inhibitory effect on hepatic sclerosis induced by $CCl_4$ and further ultimately prevent liver cirrhosis. To obtain more credible results in this experiment, the invention of a new experimental model more similar to human hepatic sclerosis is still needed.

The complete blood count and serum biochemical parameters are essential tools for diagnosis and monitoring of physiological and disease conditions in dogs. These parameters may be affected by the breed and age of dogs. This study aimed to compare the changes of complete blood count and serum biochemical parameters according to the increasing age in 156 Sapsarees. In this study, the Sapsarees were clustered into ten age groups: four to six months, seven to nine months, ten to twelve months, one year, two years, three to four years, five to six years, seven to eight years, nine to ten years, and, eleven to twelve years old. In the result of the complete blood count, the total red blood cell count (P<0.001), hematocrit (P<0.001), and hemoglobin (P<0.001) values were significantly increased from 4~6 months to 2 years old Sapsarees. While the mean corpuscular volume (P<0.001) and mean corpuscular hemoglobin (P<0.001) values were significantly increased from 4~6 months to 3~4 years old. The mean corpuscular hemoglobin concentration was significantly (P=0.037) increased from 4~6 to 10~12-month-old Sapsarees. Total white cell count was significantly (P<0.001) decreased from 1 year to 9~10 years old. The result of differential white blood cell count showed that neutrophil count was significantly (P<0.001) increased from the age 4~6 months to 11~12 years old Sapsarees, whereas, lymphocyte (P<0.001), monocyte (P<0.001), and eosinophil (P=0.042) counts were significantly decreased from 7~9 months to 7~8 years, 4~6 months to 9~10 years, 3~4 to 5~6 years old, respectively. In the serum biochemistry result, the creatinine concentration was significantly (P<0.001) increased from 4~6 to 10~12 months, but significantly (P=0.006) decreased from 7~8 to 10~12 years old. Phosphate concentration was significantly (P<0.001) decreased from 3~4 to 9~10 years old, but significantly (P=0.021) increased from 9~10 to 11~12 years old. Calcium concentration significantly (P<0.001) decreased from 10~12 months to 11~12 years old. Total protein concentration significantly (P<0.001) increased from 4~6 months to 2 years old. While concentrations of albumin (P=0.004) and globulin (P<0.001) was significantly increased from 4~6 months to 3~4 years old, and from 4~6 months to 11~12 years old, respectively. The alkaline phosphate concentration was significantly (P<0.001) decreased from 4~6 months to 2 years old. We found that there are differences in the hematological parameters in relation with the increasing age in Sapsaree breed.

Objective: To evaluate the association between the severity of endometriosis and the preoperative neutrophil-to-lymphocyte ratio (NLR) and serum level of cancer antigen 125 (CA 125). Methods: Data were obtained from the medical records of 419 patients who underwent laparoscopic conservative surgery for ovarian endometrioma between April 2005 and March 2013. Each patient's preoperative complete blood count was recorded and the endometriosis score was assessed. Results: The endometriosis score was not associated with either the NLR or the serum level of CA 125. The endometriosis score was negatively related to preoperative hemoglobin, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration. The only positive association was between NLR and the patients' age. NLR and preoperative serum anti-M$\ddot{u}$llerian hormone level were found to be negatively related. Conclusion: The severity of endometriosis was not associated with the serum level of CA 125 or the NLR. The presence of a negative correlation between the severity of endometriosis and red blood cell dynamics needs further investigation.

A 12-year old neutered male Yorkshire terrier dog was presented to the Veterinary Medical Teaching Hospital of Seoul National University with a history of chronic intermittent diarrhea, vomiting, anorexia and weight loss of 2-months duration. On presentation, he was very cachexic and had ascites. Abnormal findings on a complete blood count and chemistry profile included mild anemia, leukocytosis, panhypoproteinemia, hypocholesterolemia, decreased blood urea nitrogen (BUN) and increased serum bile acids. Radiographic findings indicated microhepatica. Peritoneal fluid analysis was consistent with transudates (total protein < 2.5 g/dl, total nucleated cell count = 2,200/ul) and cytologic examination of the fluid revealed neoplastic lymphoblasts. From these findings hepatic dysfunction and protein-losing enteropathy were attributable to abdominal lymphoma. This case suggests that cytologic examination is important in diagnosing underlying diseases of ascites, even if it is transudative effusion.

Purpose: Hemophagocytic lymphohistiocytosis (HLH) is a hyperinflammatory syndrome with many causes, including Kawasaki disease (KD). The purpose of this study was to identify the laboratory tests needed to easily differentiate KD with HLH from incomplete KD alone. Methods: We performed a retrospective study on patients diagnosed with incomplete KD and incomplete KD with HLH (HLH-KD) between January 2012 and March 2015. We compared 8 secondary HLH patients who were first diagnosed with incomplete KD with all 247 incomplete KD diagnosed patients during the study period. The complete blood count, erythrocyte sedimentation rate, platelet count, and serum total protein, albumin, triglyceride, C-reactive protein, N-terminal pro-brain natriuretic peptide (NT-proBNP), and ferritin levels were compared. Clinical characteristics and echocardiography findings were also compared between the 2 groups. Results: The total duration of fever was longer in the HLH-KD group than in the KD group. White blood cell and platelet counts were higher in the KD group. Alanine aminotransferase, ferritin, and coronary artery diameter were increased in the HLH-KD group compared with those in the KD group. The median of NT-proBNP was significantly higher in the HLH-KD group than in the KD group at 889.0 (interquartile range [IQR], 384.5-1792.0) pg/mL vs. 233.0 (IQR, 107.0-544.0) pg/mL. Conclusion: The NT-proBNP level may be helpful in distinguishing incomplete KD from KD with HLH. The NT-proBNP level should be determined in KD patients with prolonged fever, in addition to the white blood cell count, platelet count, and ferritin level, to evaluate secondary HLH.
