Constituents of animal biofluids such as milk, blood and urine contain information specifically related to metabolic and health status of the ruminant animals. Some changes in composition of biofluids can be attributed to disease response of the animals. Mastitis is a major problem for the global dairy industry and causes substantial economic losses from decreasing milk production and reducing milk quality. The purpose of this study was to investigate potential of NIRS combined with multivariate analysis for cow's mastitis diagnosis based on NIR spectra of milk, blood and urine. A total of 112 bulk milk, urine and blood samples from 4 Holstein cows were analyzed. The milk samples were collected from morning milking. The urine samples were collected before morning milking and stored at -35$^{\circ}C$ until spectral analysis. The blood samples were collected before morning milking using a catheter inserted into the carotid vein. Heparin was added to blood samples to prevent coagulation. All milk samples were analyzed for somatic cell count (SCC). The SCC content in milk was used as indicator of mastitis and as quantitative parameter for respective urine and blood samples collected at same time. NIR spectra of blood and milk samples were obtained by InfraAlyzer 500 spectrophotometer, using a transflectance mode. NIR spectra of urine samples were obtained by NIR System 6500 spectrophotometer, using 1 mm sample thickness. All samples were divided into calibration set and test set. Class variable was assigned for each sample as follow: healthy (class 1) and mastitic (class 2), based on milk SCC content. SIMCA was implemented to create models of the respective classes based on NIR spectra of milk, blood or urine. For the calibration set of samples, SIMCA models (model for samples from healthy cows and model for samples from mastitic cows), correctly classified from 97.33 to 98.67% of milk samples, from 97.33 to 98.61% of urine samples and from 96.00 to 94.67% of blood samples. From samples in the test set, the percent of correctly classified samples varied from 70.27 to 89.19, depending mainly on spectral data pretreatment. The best results for all data sets were obtained when first derivative spectral data pretreatment was used. The incorrect classified samples were 5 from milk samples,5 and 4 from urine and blood samples, respectively. The analysis of changes in the loading of first PC factor for group of samples from healthy cows and group of samples from mastitic cows showed, that separation between classes was indirect and based on influence of mastitis on the milk, blood and urine components. Results from the present investigation showed that the changes that occur when a cow gets mastitis influence her milk, urine and blood spectra in a specific way. SIMCA allowed extraction of available spectral information from the milk, urine and blood spectra connected with mastitis. The obtained results could be used for development of a new method for mastitis detection.

The growth responses of a variety of human Intestinal bacteria to extracts of Pun(1.vKy'n.ieny and five other oriental medicinal Araliaceae were evaluated in vitro and in vivo. The extracts enhanced the growth of Bifidobncterilim breve and B. longum in Media with or without carbon sources, suggesting the bifid factor (5) might be involved in the phenomenon. This effect was most pronounced with water extract of p. ginseng, the growth of 27 bifidobacteria strains belonging to B. ndolexcentium, H. longlrm, and 1. breve and B. iniuntis being greatly stimurated, whereas seven B. bifidum strains and other bacteria such as clostridia and 5.fcherirhia coli had little or no ability to utilizes it (or growth. Methanol extracts of p, ginseng were found to selectively inhibit growth of various clostridia including C. perfringens and C. Paraputrificum, but this effect was not observed on other bacteria including bifidobacteria. The effect of ginseng extract intake(600 mg/day for two weeks) on the fecal microflora, pH, volatile fatty acids, ammonia, putrefactive products, and -glucuronidase, -glucosidase and nitroreductase activities, and on the blood components (triglyceride, total cholesterol and ammonia) were investigated using seven healthy human volunteers. The total concentration of fecal microflora including Bri'idobucterilim app. during the period of ginseng extract intake was significantly unaffected from the proceeding and sub sequent control periods. However, the frequency of occurrence of subjects having C. perfringens was significantly decreased. The fecal pH value was also significantly decreased, suggesting that the intake might increase the activity of Bifidobacterium spp. Other biochemical properties in faces did not changed significantly. The levels of ammonia and triglycerid in blood were decreased with ginseng extract intake. These results may be an indication of at least one of the pharmacological actions of P ginseng as an adaptogen.

본 연구에서는 40대 중년여성 16명을 벨리댄스군 8명, 대조군 8명으로 구성하여 후 벨리댄스 그룹은 12주에 걸쳐 주3회 1회 60분 동안 운동을 지속적으로 실시하여 혈액성분과 골다공증, Osteocalcin을 분석한 결론은 다음과 같다. 1. WBC는 벨리댄스 그룹이 집단간, 집단내에서 유의한 감소를 나타내었다. 하지만 RBC, Hb, PLT은 모든 그룹이 집단내, 집단간 유의한 차이를 나타내지 못했다. 2. 골밀도는 벨리댄스 그룹이 집단간 유의하게 증가하였고, 집단내에서는 유의하게 증가한 것으로 나타났다. 3. Osteocalcin은 벨리댄스 그룹내 증가양상은 보였지만 유의성은 나타나지 않았다. 이상의 결과를 통해서, 벨리댄스가 WBC와 골밀도에 유익한 변화를 가져왔으며 이로 인하여 중년여성의 건강증진과 골다공증 및 골 관련 질환의 예방을 위해 큰 도움을 줄 것이며, 아직 국내에 벨리댄스에 대한 연구가 미흡한 실정이라 향후 장기간 연구가 필요할 것으로 사료된다.

Background: Although many studies have evaluated the efficacy and pharmacokinetics of Korean Red Ginseng (KRG) components (Rg1, Rb1, Rg3, Rd, etc.), few have examined the in vivo pharmacokinetics of the radiolabeled components. This study investigated the pharmacokinetics of ginsenosides and their metabolite compound K (CK), 20(s)-protopanaxadiol (PPD), and 20(s)-protopanaxatriol (PPT) using radioisotopes in rat oral administration. Methods: Sprague-Dawley rats were dosed orally once with 10 mg/kg of the tritium(3H) radiolabeled samples, and then the blood was collected from the tail vein after 0.25, 0.5, 1, 1.5, 2, 4, 6, 8, 12, 24, 48, 96, and 168 h. Radioactivity in the organs, feces, urine, and carcass was determined using a liquid scintillation counter (LSC) and a bio-imaging analyzer system (BAS). Results and conclusion: After oral administration, as the ³H-labeled ginsenosides were converted to metabolites, C_max and half-life increased, and T_max decreased. Interestingly, Rb1 and CK showed similar values, and after a single oral administration of components, the cumulative excretion ratio of urine and feces was 88.9%-92.4%. Although most KRG components were excreted within 96-168 h of administration, small amounts of components were detected in almost all tissues and mainly distributed to the liver except for the digestive tract when observed through autoradiography. This study demonstrated that KRG components were distributed to various organs in the rats. Further studies could be conducted to prove the bioavailability and transmission of KRG components to confirm the mechanism of KRG efficacy.

광주지역의 한 종합병원 수검자를 대상으로 백혈구 수와 대사증후군과의 관련 요인을 분석하고자 단면 연구를 시행한 결과 대사증후군의 유병률은 남성이 25.2%, 여성은 13.3%로 나타났으며, 연령별 유병률은 남성은 40대에서, 여성은 60세 이상에서 가장 높은 유병률을 보였고 남녀 모두 백혈구수가 증가 할수록 대사증후군의 유병률이 높게 나타났다. 대사증후군과 백혈구수와의 로지스틱 회귀분석의 결과에서는 남, 여 모두 백혈구 수가 증가 할수록 대사증후군의 위험도가 증가하였다. 결론적으로 본 연구에서는 비록 정상범위 일지라도 증가된 백혈구 수는 대사증후군과 연관성이 있다는 것을 확인할 수 있으며, 대사증후군 기준을 충족시키는 항목수가 많을수록 백혈구 수는 증가하는 경향을 보였고, 백혈구 수를 네 개의 군으로 나누었을 때 백혈구 구분수가 증가할수록 대사증후군의 유병률도 증가하고 있었다. 백혈구수와 백혈구 감별계산이 대사증후군을 예측하는 인자로 가치가 있는지는 광범위한 대단위 연구와 시간적 순서에 의해 인과관계를 규명하는 코호트연구가 필요하다고 생각된다.

Juvenile Anoplopoma fimbria (mean length $15.6{\pm}1.4cm$, mean weight $68.7{\pm}4.3g$) were exposed to 4 months with the different levels of salinity [100 (35.0), 90 (31.5), 80 (28.0), 70 (24.5), 60 (21.0), 50 (17.5), and 40 (14.0) % (psu)] for 4 months. Hematological parameters such as red blood cell (RBC) counts, hematocrit (Ht), and hemoglobin (Hb) concentrations were substantially decreased under salinities of 50% psu or lower. Of the measured inorganic plasma constituents, magnesium was notably decreased, whereas there was no effect on calcium. Among organic plasma components, glucose and cholesterol were significantly increased, and total protein was decreased. Among enzyme plasma components, glutamic oxalate transaminase (GOT), glutamic pyruvate transaminase (GPT), and alkaline phosphatase (ALP) were significantly increased under salinities of 50% psu or lower. Antioxidant responses such as glutathione S-transferase (GST) and glutathione (GSH) were significantly decreased at salinities of 50% psu or lower. The results of this study indicate that salinity affects the blood parameters, plasma constituents, and antioxidant responses of A. fimbria.
