Objectives: The purpose of this study is to investigate the relationship between granulocyte/lymphocyte ratio and dysmenorrhea, history of gynecological disease, heart rate varibility(HRV). Methods: From May 1st 2011 to July 10th 2011, a total of 40 female subjects (age 20-39) were recruited. We evaluated the menstruation condition by questionnaires including VAS(Visual Analog Scale), VRS(Verbal Rating Scale) and MVRS (Multidimensional Verbal Rating Scale), also measured subject's WBC differential count and HRV. Results: 1. There was no statistically significant difference in granulocyte/lymphocyte ratio according to menstruation cycle, duration, amount, color, and blood clot. 2. There was no statistically significant difference in VAS, VRS, MVRS mean scores between normal group and abnormal group according to granulocyte/ lymphocyte ratio. 3. The past prevalence of gynecological disease of abnormal group showed significantly higher compared with that of normal group($x^2$=6.578, p=0.010). 4. LF/HF ratio and granulocyte ratio significantly showed positive correlation ($r_s$=0.311 p=0.048) and LF/HF ratio and lymphocyte ratio significantly showed negative correlation($r_s$=-0.319 p=0.045). Conclusion: These findings suggest that the gynecologic diseases are related to disorder of autonomic nervous system, but not dysmenorrhea. And the balance state of sympathetic/parasympathetic nerve infered through granulocyte/lymphocyte ratio and HRV seems to be consistent. However, reconfirmation through further studies is needed.

Objectives: The purpose of this study is to investigate the relationship between the degree of menopausal symptom and granulocyte/lymphocyte ratio, and heart rate varibility(HRV). Methods: From 11th April 2011 to 20th May 2011, a total 30 female subjects (age 41-60) was recruited. We evaluated the degree of menopausal symptoms by Kupperman' s index and measured subject's WBC differential count and HRV. The data were analyzed by Kruskal-Wallis test and Spearman correlation test using SPSS/PC ver 13.0 program. Results: 1. There was no statistically significant difference in granulocyte/lymphocyte ratio and HRV among 4 classified groups according to Kupperman's index.- Mild, Moderate, Severe and Urgent. 2. Granulocyte ratio and general symptom score(within Kupperman's index) significantly showed negative correlation coefficient(r=-0.499, p=0.005), and Lymphocyte ratio and general symptom score significantly showed positive correlation coefficient (r=0.374, p=0.042). 3. Granulocyte/lymphocyte ratio and HRV showed no significant correlation. Conclusions: There was no significant relation among the degree of menopausal symptoms and granulocyte/lymphocyte ratio, and HRV. But furthermore large scale study is required.

Purpose: The aim of this study was to investigate the relation between peripheral blood leukocyte differential - Granulocyte rate, Lymphocyte rate and its calculated Granulocyte/Lymphocyte ratio - and the obstetric variables. Methods: From 270 cases of women who were in the postpartum care center attached to Won-Kwang Korean Medical Hospital, 36 cases met exclusion criteria. On the obstetric variables of 234 cases, peripheral blood leukocyte differential - Granulocyte rate, Lymphocyte rate and its calculated Granulocyte/Lymphocyte ratio - was analyzed. In the postpartum care center, the obstetric variables were asked of 234 cases of women, and who measured leukocyte differential. Results: Mean granulocyte rate and lymphocyte rate of peripheral blood leukocyte differential showed statistically significant difference from those in healthy people and was high. There was statistically significant difference in granulocyte/lymphocyte ratio according to mood of delivery, parity and period passed from childbirth. But whether postpartum women with anemia or not, maternal age and gender of neonate were not associated with granulocyte/lymphocyte ratio, and which was not significantly correlated with gestational age and neonatal birth weight. Conclusions: These findings suggest that activation of the sympathetic nervous system in postpartum women is higher than in healthy people. And granulocyte/lymphocyte ratio was influenced by mood of delivery, parity and period passed from childbirth. In future, more studies or surveys, with less bias, for the relation between peripheral blood leukocyte differential and the obstetric variables are required.

목적 : 방사선 치료시 주기적으로 시행하는 말초 혈액 검사에서 백혈구 성분 중 림프구 수의 감소가 관찰되어, 저자는 방사선 치료 전, 후의 백혈구 성분 및 림프구 아형 분석을 시도하여 방사선 치료가 각 성분에 미치는 영향의 정도를 알아보고자 하였다. 대상 및 방법 : 1994년 12월부터 1995년 5월까지 동아대학교병원 치료방사선과에 내원한 환자 중 16명(폐암, 담관암, 식도암 : 2예, 뇌송과체 종양, 위암, 직장암, 악성 흑색종, 안상 배세포종, 방광암, 전립선 육종, 성상세포종, 다형성교모세포종, 다발성 골전이 폐암 : 1예)을 대상으로 하였다. 방사선 치료는 2700 cGy에서 6660 cGy까지 시행하여 정중앙 총 방사선량이 5400 cGy였다. 백혈구 및 감별계산에서 방사선 치료 전과 후의 백혈구 및 림프구, 단핵구, 과립구의 절대값과 백분을을 구하였고 림프구 아형의 분석은 유세포분석기를 이용하여 총 T 세포, 총 8 세포, 조력유발 T 세포, 억제유발 T 세포, 자연살해세포 등의 절대값과 백분유을 구하였다. 방사선 치료 전후의 절대값파 백분율을 비교하였으며 조력유발T세포에 대한 억제유발 T 세포의 비(Helper/Suppressor T cell ratio)의 변화도 분석하였다. 나아가 방사선량에 따른 각 구성비의 변화 정도를 분석하여 총 방사선량과의 상관 관계를 유추하고자하였다. 결과 : 각 환자에서 방사선 치료 전후에 측정한 값의 비교에서, 백혈구와 그 구성 성분인 림프구, 단핵구및 과립구의 수는 단핵구를 제외하고는 방사선 치료 전에 비하여 감소하였으며 특히 림프구 수의 감소는 통계적으로 유의한 차이를 보였다(p<0.05). 림프구 아형인 총 T 세포, 총 B세포, 조력유발 T 세포, 억제유발 T 세포, 자연살해세포 모두 치료전에 비해 감소하였으며(p$\geq$0.05), 조력유발 T 세포에 대한 억제유발 T 세포의 비(Helper/Suppressor T cell ratio)는 방사선 치료 전 1.52에서 치료후 1.11로 감소하였고(p<0.05) 방사선량에 따른 조력유발 T 세포에 대한 억제유발 T 세포의 비의 방사선 치료 전후에 50 Gy 미만군(5명)과 50 Gy 이상군(11명)에서 각각 0.75와 0.71이었다. 결론 : 방사선 치료 후 림프구 수와 조력유발 T 세포에 대한 억제유발 T 세포의 비는 감소하였고 억제유발 T 세포의 백분율은 증가하였다. 이상의 결과로 림프구 아형 중 조력유발 T 세포가 억제유발 T 세포보다 방사선에 보다 민감한 것으로 사료된다. 본 실험에서 방사선량에 따른 림프구 성분의 변화 분석은 대상군 수가 적고 일회 분할 방사선량이나 치료 부위의 넓이, 환자의 체표 면적의 차이에 따른 제한적 요소가 있었으며 향후 보다 많은 대상군에 대한 심도 깊은 분석이 요구된다.

In recent years, global warming is causing dramatic environmental changes and deterioration, such as hypoxia, leading to reduced survival rate and growth performance of farmed aquatic animals. Hence, understanding systemic immuno-physiological changes in fish under environmental stress might be important to maximize aquaculture production. In this study, we investigated physiological changes in rainbow trout exposed to hypoxic stress by monitoring changes in blood chemistry, leukocyte population, and expression levels of related cytokine genes. Hematological and serological factors were evaluated in blood obtained from rainbow trout sampled at a dissolved level of 4.6 mg O₂ L^-1 and 2.1 mg O₂ L^-1. Blood and head kidney tissue obtained at each sampling time point were used to determine erythrocyte size, leukocyte population, and cytokine gene expression. The level of LDH and GPT in fish under progressive hypoxia were significantly increased in plasma. Likewise, the (Granulocyte + Macrophage)/lymphocyte ratio (%) of fish exposed to hypoxia was significantly lower than that in fish in the control group. Such changes might be due to the rapid movement of lymphocytes in fish exposed to acute hypoxia. In this study, significant up-regulation in expression levels of IL-1β and IL-6 gene appeared to be involved in the redistribution of leukocytes in rainbow trout. This is the first study to demonstrate the involvement of cytokines in leukocyte trafficking in fish exposed to hypoxia. It will help us understand systemic physiological changes and mechanisms involved in teleost under hypoxic stress.

This study investigated the effects of dietary rumen-protected L-tryptophan (TRP) supplementation (43.4 mg of L-tryptophan kg^-1 body weigt [BW]) for 65 days in Hanwoo steers on muscle development related to gene expressions and adipose tissue catabolism and fatty acid transportation in longissimus dorsi muscles. Eight Hanwoo steers (initial BW = 424.6 kg [SD 42.3]; 477 days old [SD 4.8]) were randomly allocated to two groups (n = 4) of control and treatment and were supplied with total mixed ration (TMR). The treatment group was fed with 15 g of rumen-protected TRP (0.1% of TMR as-fed basis equal to 43.4 mg of TRP kg^-1 BW) once a day at 0800 h as top-dressed to TMR. Blood samples were collected 3 times, at 0, 5, and 10 weeks of the experiment, for assessment of hematological and biochemical parameters. For gene study, the longissimus dorsi muscle samples (12 to 13 ribs, approximately 2 g) were collected from each individual by biopsy at end of the study (10 weeks). Growth performance parameters including final BW, average daily gain, and gain to feed ratio, were not different (p > 0.05) between the two groups. Hematological parameters including granulocyte, lymphocyte, monocyte, platelet, red blood cell, hematocrit, and white blood cell showed no difference (p > 0.05) between the two groups except for hemoglobin (p = 0.025), which was higher in the treatment than in the control group. Serum biochemical parameters including total protein, albumin, globulin, blood urea nitrogen, creatinine phosphokinase, glucose, nonesterified fatty acids, and triglyceride also showed no differences between the two groups (p > 0.05). Gene expression related to muscle development (Myogenic factor 6 [MYF6], myogenine [MyoG]), adipose tissue catabolism (lipoprotein lipase [LPL]), and fatty acid transformation indicator (fatty acid binding protein 4 [FABP4]) were increased in the treatment group compared to the control group (p < 0.05). Collectively, supplementation of TRP (65 days in this study) promotes muscle development and increases the ability of the animals to catabolize and transport fat in muscles due to an increase in expressions of MYF6, MyoG, FABP4, and LPL gene.
