The purpose of this study was to investigate the possibility of medicinal plants application as an edible functional food resource. We carried out to develop a traditional functional beverage by using hot-water extraction of 4 medicinal plants (Polygonatun sibiricum, Ophiopogonis radix, Lycii fructus, Schizandriae frutcus) and we examined the effects of drink on physiological response during exercise and recovery phase. The subjects were male baseball players, and exercise protocol was performed with 45 minutes treadmill running and 85％ VO$_2$ max intensity. Brix, pH and titratable acidity of developed drink were 9.5％, 3.3 and 0.22％. The approximate nutritional composition of beverage was carbohydrate, 5.98％, total dietary fiber, 0.42％, crude protein, 0.70％, crude fat, 0.20％ and crude ash, 0.20％. Developed. traditional functional beverage contained K (4.00 mg％), Na (3.68mg％), Ca (2.54mg％), Mg (1.60mg％) and Fe (0.29mg％). Developed beverage drinking group showed a lowest heart rate during exercise and recovery phase than the other two group (water group and ion beverage group). In the change of blood lactate concentration, developed beverage intake group showed a significant lowest values during exercise and recovery phase. And blood hematocrit values and osmolarity were lowest in the developed beverage intake group. In these results, exercise performance capacity was expected to improve most highly with the developed drink from composition with medicinal plants. Also developed beverage was effective in recovery of exercise-induced fatigue. Thus developed drink with medicinal plants can be used as a functional material improving decrease fatigue effects in beverage industry.

To determine the effects of exposure to formalin on the secondary stress indices, changes in haematology and blood chemistry were monitored in healthy crucian carps (Carassius auratus). Fishes were separately exposed in a concentration range of 125 to 500 ppm formalin for 60 min. After exposure, red blood cell (RBC) count and packed cell volume (PCV) were elevated in the 500 ppm formalin exposed group. However, mean corpuscular volume (MCV) and mean corpuscular haemoglobin (MCH) were decreased significantly in the 500 ppm formalin exposed group. Total protein, albumin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine, total bilirubin, inorganic phosphorus (IP) and magnesium were significantly increased at a concentration of 500 ppm. Alkaline phosphatase (ALP) and glucose were increased at a concentration of 500 ppm, but this was not significant. Lactate dehydrogenase (LDH) and calcium were significantly decreased at concentrations of 250 and 500 ppm. AST, ALT, glucose and magnesium were significantly increased in the 250 ppm formalin exposed group. These results suggests that formalin exposure might cause some damage in the liver and kidney of crucian carp.

Background: Mycobacterium avium subspecies paratuberculosis (MAP) causes a chronic and progressive granulomatous enteritis and economic losses in dairy cattle in subclinical stages. Subclinical infection in cattle can be detected using serum MAP antibody enzyme-linked immunosorbent assay (ELISA) and fecal polymerase chain reaction (PCR) tests. Objectives: To investigate the differences in blood parameters, according to the detection of MAP using serum antibody ELISA and fecal PCR tests. Methods: We divided 33 subclinically infected adult cattle into three groups: seronegative and fecal-positive (SNFP, n = 5), seropositive and fecal-negative (SPFN, n = 10), and seropositive and fecal-positive (SPFP, n = 18). Hematological and serum biochemical analyses were performed. Results: Although the cows were clinically healthy without any manifestations, the SNFP and SPFP groups had higher platelet counts, mean platelet volumes, plateletcrit, lactate dehydrogenase levels, lactate levels, and calcium levels but lower mean corpuscular volume concentration than the SPFN group (p < 0.017). The red blood cell count, hematocrit, monocyte count, glucose level, and calprotectin level were different according to the detection method (p < 0.05). The SNFP and SPFP groups had higher red blood cell counts, hematocrit and calprotectin levels, but lower monocyte counts and glucose levels than the SPFN group, although there were no significant differences (p > 0.017). Conclusions: The cows with fecal-positive MAP status had different blood parameters from those with fecal-negative MAP status, although they were subclinically infected. These findings provide new insights into understanding the mechanism of MAP infection in subclinically infected cattle.

Background: This study examined whether activation of innate immunity and alterations of carbohydrate and lipid metabolism precede development of subclinical mastitis (SCM). Methods: Blood samples were collected from the coccygeal vein from 100 Holstein dairy cows at -8, -4, disease diagnosis week, and +4 weeks postpartum. Six healthy cows (controls - CON) and six cows that showed clinical signs of SCM were selected for serum analyses. All serum samples were analyzed for acute phase proteins (APP) haptoglobin (Hp) and serum amyloid A (SAA); proinflammatory cytokines including interleukin 1 (IL-1), IL-6, and tumor necrosis factor (TNF) and serum lactate, BHBA, and NEFA concentration. Data of DMI, milk production, and milk composition were recorded and analyzed. Results: The results showed that cows with SCM had greater concentrations of SAA, TNF (P < 0.01), and lactate before expected day of parturition (P < 0.05) compared to CON cows. Cows with SCM showed greater concentrations of lactate starting at -8 weeks (P < 0.05) and TNF starting at -4 weeks prior to the expected day of parturition (P < 0.01). Interestingly, at -4 weeks, concentrations of IL-1 and Hp were lower in cows with SCM compared to healthy cows (P < 0.01) followed by an increase during the week of disease diagnosis (P < 0.05). Subclinical mastitis was associated with lower DMI, at -4 weeks before calving, milk production (P < 0.05) and increased somatic cell counts (SCC) (P < 0.01). Conclusions: Results of this study suggest that SCM is preceded by activated innate immunity and altered carbohydrate metabolism in transition dairy cows. Moreover the results support the idea that Hp, lactate, and SAA, at -8 weeks, and TNF and IL-1 at -4 weeks can be used as early indicators to screen cows during dry off for disease state.

We investigated the effects of plant vinegar on platelets and blood coagulation system. Plant vinegar inhibited in vitro platelet aggregation in a concentration dependent manner, when platelets were activated by thrombin and collagen. In addition, plant vinegar showed inhibitory effects on the serotonin secretion induced by thrombin in a concentration dependent manner. However, treatment with plant vinegar to platelets did not induce any cytotoxicity, as determined by the release of lactate dehydrogenase. Plant vinegar did not change the coagulation parameters such as activated partial thromboplastin time (aPTT) and prothrombin time (PT) using rat citrated plasma. In vivo study revealed that, treatment with plant vinegar prolonged the bleeding time from mouse tail. All these results suggest that plant vinegar might improve blood hemostasis mediated via anti platelet activities.

상심자 추출물이 운동에 의한 체내 monoamine oxidase (MAO) 활성 변화에 미치는 영향을 연구하여. 상심자 추출물을 경구투여(0.3g/kg body weight) 한 흰쥐의 뇌와 간에서 MAO-A와 MAO-B의 활성에 중요한 영향을 미치는 사실을 확인하였다. 각 효소활성은 serotonin과 benzylamine을 기질로 이용하여 측정하였다. 운동 전 후 운동의 유형에 따라 효소활성의 변화경향이 서로 다른 경향을 나타내었다. 뇌에서 측정한 MAO-A 활성은 운동에 의해 효소활성이 현저히 감소하였으며 반면, 간에서 측정한 MAO-B의 활성은 운동이 끝나고 60분이 경과할 때까지 증가된 상태를 유지하고 있었다. 운동 시 체내 변화의 지표효소인 혈중 LDH의 활성 변화와 혈중 lactate의 농도변화를 함께 관찰함으로서 MAO 활성과의 상관관계를 비교하였다. 상심자 추출물을 경구투여 하고 운동을 한 동물의 MAO-A 활성은 증가하였고 MAO-B, LDH 활성과 lactate level은 감소하는 것을 확인하였다. 결과적으로 모은 지표들이 운동 전의 정상상태로 회복되는 것으로 확인되었다. 이 연구의 결과들로부터 상심자 추출물이 운동 전후의 MAO 활성을 조절함으로써 운동능력을 향상시키고 피로를 회복하는 효능을 갖는 것으로 추정되며 이러한 기능성을 갖는 건강기능식품의 소재로 활용이 가능할 것으로 생각한다.

The aim of this was to evaluate the effects of Rhus Verniciflua Stoke (RVS) extract powder on the endurance capacity for the forced swimming mice. Thirty mice were divided into 3 groups including negative control, 250 (RVS-250) and 500 (RVS-500) mg/kg RVS extract powder groups for 4-times swimming exercises. The swimming times to exhaustion in RVS-250 and RVS-500 mice were prolonged 1.6- and 2.0-fold at 4 weeks compared with negative control mice, respectively. Blood biochemical parameters for AST, ALT, T-CHO and TG were not significantly different between RVS fed or negative control mice. However, blood concentration of creatinine was significantly increased in RVS-250 mice, but not in RVS-500 mice. During the longer swimming exercise in RVS group, blood glucose and lactate levels were significantly decreased, but free fatty acid not changed. And also LDH levels were significantly decreased in RVS groups compared to negative control mice. Hepatic lipid peroxidation was not affected by RVS, but SOD and catalase activity were significantly increased in RVS groups. Interestingly, the levels of testosterone and free testosterone were significantly increased in RVS groups before swimming exercise, but they were not significantly changed among groups after swimming exercise. The present results suggest that RVS extract powders may enhance swimming exercise performance by recovering the exercise-fatigue via reduction of blood LDH activity and by burning blood glucose as an energy source. These results imply that RVS-produced testosterone may act as an energy buster to enhance physical activity.

This experiment was carried out to observe a biological effect of ginseng on the weight gain, physical performance and lactic acid production after exercise in mice. A group of mice weighing about 19 gm was divided into ginseng and cotrol group. on the treadmill (Exp. I & II) and LDH activity of liver and heart homogenates (Exp. II) were determined. Results are summerized as follows; 1. Body weight gain was greater id ginseng group than in control and the difference was statistically significant at 9th and 16th days of experimental period. 2. Maximal running time of ginseng was found to be longer than that of control (p<0.05) in experiment I and the experiment II also revealed the significant increase in maximal running time in ginseng group. 3. Bloo lactate concentration of 48 hour-rest from physical exertion was lower in ginseng group than in control (p<0.05). 4. LDH activity in liver homogenate was lower compared to control group, but in heart homogenate, it was greater in ginseng group. Above findings may be concluded tat the range of biological dose (20 mg/mice/day) of ginseng powder stimulated the body weight gain and increase of physical performance and its mechanism might be attributable to a lower level of blood lactic acid. The adaptive change of LDH activity also contributed to the change in lactate level in blood and tissue.
