Production of high-quality horses is important to make the horse industry grow. Grazing during the growing period can be an important factor affecting the production of high-quality horses. The objective of this study was to determine the effects of grazing on growing horses by analyzing their blood components and intestinal microbiota. Twelve growing horses for evaluating blood components and ten growing horses for evaluating intestinal microbiota were raised for about seven months and separated by two treatments: grazing vs. stable. Complete blood count, blood chemistry, and creatine kinase levels were analyzed as blood components and a 16s rRNA gene sequence analysis was performed to analyze intestinal microbiota. Calcium ions tended to be lower in the group with grazing treatment. Alkaline phosphatase and creatine kinase tended to be higher in the group with grazing treatment. These results indicate that grazing can provide horses with more exercise than staying in stables. At the phylum level, Firmicutes/Bacteroidetes ratios in grazing and stable groups were 4.2 and 6.5, respectively. Because various studies have reported that a. high Firmicutes/Bacteroidetes ratio indicates obesity, the method of raising horses might affect their physical ability. At the species level, rates of Clostridium butyricum in grazing and stable groups were 3.2% and 13.1%, respectively. Some strains of C. butyricum can cause several diseases such as botulism. These results indicate that grazing can positively affect growing horses in terms of blood components and intestinal microbiota. Moreover, grazing can be helpful to make growing horses healthy through proper exercise.

The purpose of this study was to develop hydrolysate from silkworm (Cudrania Silkworm Fibroin Peptide; CSFP), a food containing components for improving blood vessel health. In general, Cudrania tricuspidata leaves contain about 5 times more rutin and 25 times more dihydroquercetin than mulberry leaves. 1-Deoxynojirimycine (1-DNJ), dihydroquercetin and rutin inhibit the activity of carbohydrate-digesting enzymes, inhibit blood lipid peroxidation, and regulate insulin secretion, which helps blood vessels to be healthy. When the diet-controlled silkworm was enzymatically hydrolyzed, it was confirmed that rutin content was about 8 times higher than that of the in general silkworm as a control. In the silkworm hydrolysate, CSFP, developed as a final food material, the active ingredients were 65 mg/kg for rutin, 3,328 mg/kg for DNJ, 0.43 mg/kg for dihydroquercetin, and 82,624 mg/kg for total polyphenol, which was confirmed through LC-MS/MS analysis. In conclusion, it was found that silkworms fed with C. tricuspidata leaves as a diet had more active components that can help control blood sugar and improve blood vessel health than silkworms fed with mulberry leaves.

Objective: This study was conducted to compare growth performance, blood components and carcass traits by two feeding systems (concentrate with roughage separately [CON] vs total mixed ration [TMR]) in Hanwoo steers, and to learn the relationship between blood components during fattening or finishing phases and carcass traits in Hanwoo steers. Methods: Sixty steers aged 8 months were allotted to two feeding systems and fed similar amounts of average dry matter and total digestible nutrient throughout whole experimental period according to each feeding program. Steers were weighed monthly, taken blood at the end of growing, fattening and finishing periods, and slaughtered at 30 month of age. Results: Growing performance was higher (p<0.05) in the CON group compared to the TMR group during fattening and finishing periods. The CON group was lower (p<0.05) in blood aspartic acid transaminase, blood urea nitrogen and retinol levels during growing period, but higher in triglyceride and cholesterol levels during fattening and finishing periods compared to the TMR group. The CON group was greater (p<0.05) in rib-eye area, and lighter (p<0.05) red in meat color compared to the TMR group. In the correlation coefficients between blood components of steers and carcass traits, retinol had a negative (p<0.05) correlation with marbling score and rib-eye area. Leptin had a positive (p<0.05) correlation with back fat thickness. Blood cholesterol and triglyceride were positively (p<0.05) correlated with carcass weight and rib-eye area. Conclusion: Growth performance, carcass ribeye area and meat color showed a more desirable result in the CON compared to the TMR in Hanwoo steers. Assessing the accumulated data of carcass traits with blood components including hormones-particularly retinol, cholesterol, triglyceride, and leptin-during the fattening or finishing phases, it may be possible to find a biomarker for determining beef quality in living animals.

Purpose: The purpose of this study was to evaluate the effects of hand moxa and hand press pellet on blood pressure, blood lipids and blood cell components in elderly women. Methods: This study was conducted as a quasi-experiment with none equivalent control group pre-post test design. The participants were elders who had essential hypertension. There were 18 members in the experimental group and 20 members in the control group. The experimental group received hand moxibustion and hand press pellet 3 times a week for 12 weeks. The results were analyzed using $x^2$ test, t-test, Fisher's exact test and repeated measures ANOVA with the SPSS/WIN program. Results: There were significant decreases in blood pressure in the experimental group compared to the control group. No significant difference was observed in total triglyceride, LDL cholesterol and HDL cholesterol between the two groups. Differences in hemoglobin and hematocrit were not significant either. However, there were significant increases in RBC in the experimental group after the intervention. Conclusion: The results suggest that combined hand therapy contributes to the decrease of blood pressure among the elderly with hypertension. Therefore combined hand therapy is recommended as a complementary nursing intervention strategy for the elderly with essential hypertension.

점탄성 응고 검사법은 전혈 검사법으로 혈장성분뿐 아니라 응고 과정의 세포 기반 측면까지 동시에 볼 수 있는 방법이다. 프로트롬빈시간이나 활성화부분트롬보플라스틴시간과 같은 기존의 응고 검사법과 달리 이 검사는 현장 현시 검사로 즉시 시행할 수 있다. 점탄성 응고 검사법은 사망률 등의 예후 예측 인자이고, 응고 장애를 좀 더 예민하게 감지하여 결과적으로 출혈을 줄여주는 효과를 줄 수 있다. 점탄성 응고 검사 결과를 이용한 수혈 전략이 수혈 요구량을 줄여주었다고 보고되기도 하였다. 아직 이 방법의 정확성과 신뢰도에 대한 우려가 있기도 하지만, ROTEM 등의 점탄성 응고 검사법은 환자혈액관리에 응용하는 것은 유용할 것이다.

In this study, we examined gangliosides from streptozotocin-induced diabetic rat brain. To obtain the diabetic rat brain, we sacrified the rat three days after injecting the streptozotocin into venus in tail. We measured blood glucose level according to Somogy-Nelson method and measured insulin level using $^{125}$ I-insulin RIA kit. The gangliosides were extracted according to Folch-Suzuki method from the rat brain. We also examined the effect of major lipid components extracted from deer antler on diabetic rat brain. The results showed that the major lipids components lowered both blood glucose and insulin level in normal rat. However only the blood glucose level in diabetic rat was lowered with major lipid components. In diabetic rat brain, gangliosides metabolism were changed. The amount of GMla was increased while GDla, GDlb, and GTlb were not synthesized. Furthermore, undefined ganglioside was found. In major lipid component-treated diabetic rat brain, the ganglioside metabolism proceeded as same as the normal rat. On the contrary, in bovine brain gangliosides-treated diabetic rat brain, the gangliosides metabolism was not recovered to normal one.

생물학 영역에서 혈액 순환은 복잡하고 추상적인 개념으로 학생들이 이해하기 어렵고, 오개념이 많아 수업 후에도 쉽게 변화하지 않는 것으로 알려져 있다. 본 연구는 혈액 순환 개념의 존재론적 속성에 따른 학생들의 개념 이해도를 학교 급별로 조사 분석하고, 혈액 순환에 대한 학생들의 이해 향상을 위한 기초자료를 제공하는데 그 목적이 있다. 이 연구는 세 부분으로 나누어 진행하였다. 첫째로, 순환 개념을 심장, 혈관, 혈액 순환으로 구분하여, 각 개념의 구조, 기능, 행동, 기작 요소별로 학생들의 이해를 알아보기 위한 개념 검사지를 개발하였다. 두 번째로 개념 검사지를 중학교, 고등학교, 대학교 학생들에게 적용하여 순환 개념의 요소별로 학교 급에 따라 개념 이해 수준이 어떻게 다른지를 비교하고, 학생들의 순환 경로의 유형을 구분하였다. 마지막으로 개념이해가 낮은 요소에 대한 개념의 존재론적 범주를 분석하여 그 특성을 파악함으로써, 개념의 범주 간 이동을 촉진시키는 수업 전략을 구성하는데 도움을 주고자 하였다. 본 연구 결과, 혈액순환 개념 중 구조나 기능 요소는 중학생, 고등학생, 대학생이 모두 높은 이해 수준을 보였고 학교 급별로 큰 차이가 없었으나, 행동이나 기작 요소에 대한 이해는 자연계열 고등학생과 대학생들에서 뚜렷하게 높아졌다. 학생들의 혈액 순환 모형은 7가지 유형으로 구분할 수 있었으며, 자연계열 고등학생들과 대학생들은 이중 분지형의 비율이 다른 학교 급에 비해 상대적으로 높았다. 또한 학생들의 순환 기작에 대한 존재론적 범주를 분석한 결과, 평형-독립적 범주의 개념을 사건-목적 범주로 인식하는 경우가 많아, 개념에 대한 잘못된 존재론적 범주의 인식이 개념 이해를 어렵게 한 원인으로 여겨진다.

In order to investigate sedative action of detomidine and its effect on physical signs, hematological and blood chemical components, 15 Holstein cattle were used. The dosage of detomidine was 25 ${\mu}$g/kg and 50 ${\mu}$g/kg. Blood was collected before injection, 30, 60 and 120 min. after injection. Induction time of sedation in a cattle given with 25 ${\mu}$g/kg and 50 ${\mu}$g/kg of detomidine was 10.6${\pm}$2.8. 7.6${\pm}$1.0min. respectively and maintenance time was 70.4${\pm}$8.3, 86.5${\pm}$9.9, respectively. After injection of detomidine, body temperature was slightly increased, heart rate and respiratory rate were slightly decreased. The levels of red blood cell, hemoglobin, packed cell volume and white blood cell were not changed by detomidine. Blood glucose level following detomidine was markedly increased but total protein, serum glutamic oxaloacetic transminase, alkaline phosphatase, lactic dehydrogenase, blood urea nitrogen and creatinine were not changed. This results indicated that detomidine was useful sedative in bovine practice.

Purpose: The purpose of this study was to examine the relationship between pigmental reaction and blood components, such as white blood cell (WBC), lymphocyte, monocyte, red blood cell (RBC), hemoglobin, mean corpuscular index (mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC)), hematocrit, platelet and neutrophil segment, after Cupping Glass Therapy (CGT). Subjects: Twenty-five healthy adults participated in this study; Methods: Subjects had undergone CGT for 5 days and were divided into two groups (dark color (DCG) and light color (LCG)) depending the level of pigmental reaction. Blood was collected from each subject at the beginning of this study and recollected after 5 day s'CGT. Results: The percentage of lymphocytes was higher in LCG than in DCG after CGT (p<.01) and was significantly increased in LCD after CGT (p<.01), The number of RBC was more in DCG than in LCG both before (p<.01) and after CGT (p<.05). The amount of hemoglobin was more in DCG than in LCG both before (p<.01) and after CGT (p<.01) and was significantly increased in LCD after CGT (p<.01). Mean corpuscular index showed that both MCH (p<.05) and MCHC (p<.01) were higher in DCG than in LCG after CGT, but only MCHC before CGT (p<.01). It also showed either decreased MCV (p<.01) or increased MCHC in LCD after CGT (p<.01). Hematocrite was higher in DCG than in LCG both before (p<.01) and after CGT (p<.01). The percentage of neutrophil segments was higher in BCG than In LCG after CGT (p<.01) and was significantly decreased in LCD after CGT (p<.05). However, neither the number of WBC and platelets nor the percentage of monocytes was significantly different between DCG and LCG either before or after CGT. Conclusion: Pigmental reaction was significantly related to the changes of blood conponents after CGT. The results of this study suggest that CGT may have an effect on the components of blood cells.
