In an attempt to observe the to long-term training effects, the exercise of rope-skipping was regularly loaded to nine soldiers for nine weeks. And some physical characteristics, cardiopulinonary functions. some blood constituents were measured before, during and after the load of test exercise. treadmill running, and were compared with the pre-trained values. The results obtained were as follows: 1) Body weight, body surface area, skinfold thickness and total body fat decreased sifnificantly after the training. 2) The post-trained values of MVV and $FEF_{25%}$, increased significantly. 3) By the training, heart rates decreased very significantly in the resting, exercising and recovery periods. 4) After the training, the systolic blood pressures of the resting and recovery periods decreased meaningfully, while diastolic blood pressures increased significantly through the recovery stages. 5) In spite of the training, the respiration rates never change in both the resting and the recovery periods. 6) After the training, total cholesterol concentration of the venous blood decreased significantly in the resting the early recovery phases while the blood levels of glucose and HDL-cholesterol decreased very slightly. 7) Blood lactate concentration decreased through the recovery periods and the value of the recovery 20 and 60 minutes decreased obviously, in comparison with the pre-trained values. The above results suggest that the 9 week-training of the rope-skipping brings about the decrease of the body fat contents, the enhancement of cardiopulmonary functions and some changes in the blood constituents.

This study was conducted to examine the effects of recombinant Bovine Somatotropin (rBST), vitamin E(Vit. E) and selenium (Se) administration on the blood chemical values and hormone concentrations of serum in Hanwoo sires. Hanwoo sires were randomly assigned to five groups; 1) control, 2) rBST,0.09mg/kg body weight (BW), 3) Vit E, 1,500IU/kg BW, 4) Se 0.1mg/kg BW, 5) Vit E, 1,500IU plus Se 0.1mg/kg BW. rBST, Vit. E and Se for each experimental group were given 6 times at 15 days interval by intermuscular injection. Blood samples were collected ten times for experimental periods and separated the serum by centrifugation and stored into deep freezer. The concentration of albumin was the highest in Se group than those of any other groups (P＜0.05) and Vit. E plus Se group was significantly higher than in the control and rBST groups (P＜0.05). The concentrations of blood urea nitrogen (BUN) and creatinine were significantly higher in rBST group than any other groups (P＜0.05). The concentration of total protein in rBST, Se and Vit. E plus Se groups were significantly higher than in control group (P＜0.05). The concentrations of calcium, cholesterol,, glucose, inorganic phosphorus and triglycerides in serum were not difference in all experimental groups (P＞0.05). The concentration of estradiol was slightly higher in Se and Vit. E plus Se groups than those of any other groups, but not significantly difference among the experimental groups (P＜0.05). The concentration of testosterone was not affected by the administration of rBST, Vit. E and Se.

Objectives: Children are more susceptible to heavy metal toxicity than adults. The purpose of this study was to evaluate heavy metal concentrations in the blood of Korean preschoolers and investigate the association between metals in blood and related factors. Methods: A total of 512 subjects from 36 to 83 months of age were sampled. A questionnaire survey was performed and the levels of lead, mercury and cadmium were measured in the blood samples of all subjects. Their parents were interviewed in order to obtain information on basic characteristics, dietary patterns, socio-economic factors, and indoor/outdoor environment of the preschoolers. Multiple linear regression was used to analyze the association between the above factors and lead, mercury or cadmium concentrations. Results: The geometric mean concentrations of lead, mercury and cadmium in the blood were $1.45{\pm}1.58{\mu}g/dL$, $2.14{\pm}1.74{\mu}g/dL$ and $0.23{\pm}1.91{\mu}g/dL$, respectively. Results from multiple linear regression analysis showed that blood lead levels were associated with birth weight and paternal smoking status. Daily mercury intake from food and maternal education were also shown to influence mercury concentrations in blood. Also, blood cadmium concentrations were associated with maternal age and having a bus garage near the place of residence. Conclusion: This study suggests that smoking status, dietary patterns and the environmental status near the residence should be considered as important factors for preventable sources of heavy metal exposure in preschoolers.

The purpose of this study was to assess the effects of the superficial heat therapy on the cutaneous blood flow and the skin temperature at pre-auricular region. Two types of the superficial heat therapy-moist hot pack & infrared lamp- were applied to 20 healthy subjects(male: 10, female: 10). For each subject, the two parameters of cutaneous blood flow and skin temperature were measured before and after heat therapy, using laser doppler flowmetry(LDF). The author analyzed the differences of the effects between the two therapies and also characteristics of responsiveness between the two parameters. The results were as follows : 1. The two parameters were significantly increased after both superficial heat therapies. 2. Skin temperature showed a maximum peak immediately after both superficial heat therapies, but cutaneous blood flow showed a maximum peak 4 minutes after both superficial heat therapies. 3. Increased cutaneous blood flow after application of moist hot pack lasted longer than infrared lamp. 4. Increased skin temperature after both superficial heat therapies lasted for 60 minutes, but increased skin temperature after infrared lamp decreased more rapidly than moist hot pack. 5. Amount of changes in cutaneous blood flow after infrared lamp was larger in female than in male, but no significant gender difference was found since 20 minutes after infrared lamp. Both moist hot pack and infrared lamp showed favorable effectiveness in raising cutaneous blood flow and skin temperature. Moist hot pack was slightly superior in maintaining this effect.

Objectives: Dental plaque emits red fluorescence under a visible blue light near the ultra-violet end of the light spectrum. The fluorescence characteristics of each microorganism have been reported in several studies. The aim of this study was to evaluate changes in red fluorescence of oral microorganisms that is affected by blood in the culture media. Methods: The gram-positive Actinomyces naeslundii (AN, KCTC 5525) and Lactobacillus casei (LC, KCTC 3109) and gram negative Prevotella intermedia (PI, KCTC 3692) that are known to emit red fluorescence were used in this study. Each bacterium was activated in broth and cultivated in different agar media at $37^{\circ}C$ for 7 days. Tryptic soy agar with hemin and vitamin $K_3$ (TSA), TSA with sheep blood (TSAB), basal medium mucin (BMM) medium, and BMM with sheep blood (BMMB) were used in this study. Fluorescence due to bacterial growth was observed under 405-nm wavelength blue light using the quantitative light-induced fluorescence-digital (QLF-D) device. The red, green, and blue fluorescence values of colonies were obtained using image-analysis software and the red to green ratio (R/G value) and red to total RGB ratio (R/RGB value) were calculated for quantitative comparison. Results: The QLF-D images of the AN, LC, and PI colonies showed red fluorescence in all media, but the fluorescence of all bacteria was reduced in TSA and BMM media, compared with in TSAB and BMMB media. Both the R/G and the R/RGB values of all bacteria were significantly reduced in growth media without blood (P<0.001). Conclusions: Based on this in vitro study, it can be concluded that red fluorescence of oral bacteria can be affected by growth components, especially blood. Blood-containing medium could be a significant factor influencing red fluorescence of oral bacteria. It can be further hypothesized that bleeding in the oral cavity can increase the red fluorescence of dental plaque.

This study was conducted to investigate the effects of supplementation diets of powdered mulberry leaves on egg production, egg quality and blood characteristics in laying hens. Laying hens were fed diets for 30 days containing 0% powdered mulberry leaves (Control), 1% powdered mulberry leaves (T1), 2% powdered mulberry leaves (T2), and 5% powdered mulberry leaves (T3). The egg production, yolk weight and albumen weight were no significant difference among treatment groups. The albumen weight was significantly decreased by the supplementation of powdered mulberry leaves in all treatment groups (P<0.05). The albumen high, yolk color score, egg sell thickness and egg shell breaking strength were no significant difference. The total cholesterol and triglyceride concentration of control was higher than T3, and the high density lipoprotein (HDL)-cholesterol concentration and glucose of control were lower than treatment groups (P<0.05). The white blood cell (WBC) was significantly increased by the supplementation of powdered mulberry leaves compared to the control (P<0.05). In conclusion, these data indicate that 5% powdered mulberry leaves supplementation was most effective in decreasing total cholesterol and triglyceride and increasing HDL-cholesterol, glucose and WBC.

This study analyzed the effect on weight and average daily gain, carcass grade, and blood characteristics and immunity in case of dietary addition of pegmatite to Hanwoo steers. Relative to Hanwoo steers, initial body weight was $257.3{\pm}11.74kg$ (8-months old after birth). Forty-eight Hanwoo steers were fed for 24 months using random arrangement (4 treatment plots${\times}$4 heads${\times}$3 repeat). The treatment plot (498.75~500.82 kg) had higher weight during the early fattening stage compared with that of the control plot (474.37 kg) (p<0.05). Regarding total cholesterol of the blood, the value was similar to one during initiation of testing, but the value increased gradually based on the progress of fattening. In addition, the triglyceride was considerably low in T2~T3 plots with high addition of pegmatite during the late fattening stage compared with other treatment plots (p<0.05). This study revealed a tendency in the IgG content that represented immunity as the addition of pegmatite became higher (p>0.05). This study found that the treatment plot (441.55~452.10 kg) had higher carcass weight compared with the control plot (436.30 kg). However, this study revealed that the treatment plot (2.30~2.55 points) had higher carcass quantity grade compared with the control plot (2.11 points). This study found that the control plot (3.55 points) had higher carcass quality grade compared with the treatment plot (2.67~3.09 points) (p>0.05). With studies combined, it was determined that dietary addition of pegmatite to the feed as clay minerals in fattening Hanwoo steers would improve feed intake, body weight gain and carcass quantity grade.

Several kinds of analytic methods for genetic polymorphism in cattle, including bovine blood typing, PCR-RFLP, BoLA and microsatellite typing were described. A few respect to consider for choosing method for actual application of genetic polymorphism were emphasized. The probability of relationship between characteristics and gene concerned, repetibility and easiness of methods applied and the possibility of clarification for segregation pattern should be deliberated.
