Sachungwhan reduced hepatotoxicity induced by carbon tetrachloride($CCl_4$). Improved liver function was observed by measuring the activities of aspartate aminotransferase(AST), alanine aminotransferase(ALT), alkaline phosphatase(ALP), blood urea nitrogen(BUN), creatinine(CRE), total cholesterol(TCHO), triglyceride(TG), low density lipoprotein cholesterol(LDL-CHO), high density lipoprotein cholesterol(HDL-CHO), total protein(TP), albumin(ALB) and total bilirubin(BIL) in serum. Hepatic parameters monitored were levels of cholesterol(CHO), triglyceride(TG), malondialdehyde(MDA), content of cytochrome P450(CYP), level of glutathione(GSH), and activities of NADPH-CYP reductase, superoxide dismutase(SOD), catalase(CAT), glutathione S-transferase(GST), glutathione reductase(GR), glutathione peroxidase(GPx). The histopathological examination showed that the treatment of Sachungwhan relieved the ballooning degeneration of hepatocytes which had been generated by $CCl_4$. The results suggested that hepatoprotective effects of Sachungwhan possibly are due to their promising antioxidative activity.

This study was performed to investigate the pathphysiological side effects of chloramphenicol (CAP) on olive flounder, Paralichthys olivaceus. 150 mg/kg/bw/day of CAP was orally administered forcedly to flounder for 4 days and then the flounder was monitored for 11 days. The level of hematocrit was significantly decreased from 2 day to 3 day of CAP treatment in CAP-treated group. The levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and gamma glutamyl transferase (GGT) were slightly increased during the treatment of CAP and gradually decreased after the treatment of CAP. The levels of blood urea nitrogen (BUN) and creatinine kinase (CK), although not significant, were slightly increased during the treatment of CAP. The level of lactate dehydrogenase (LDH) was not changed during the treatment of CAP but slightly increased after the treatment of CAP. However, no histopathological changes were observed in various organ after the treatment. From these results, it is suggest that CAP can evoke several side effects on haematopoietic organs in olive flounder.

Various kinds of related parameters on hypertension such as anti-oxygen effect, ACE, weight of body, hwart and kidney, blood pressure, heartbeat rates, contents of aldosterone, catecholamine, change rates, of plasma constituents, uric acid, BUN, creatinine were determined to verify the effects on hypertension by Kamisamul-tang (KSMT). And the results are concluded as follows. KSMT did not show any cytotoxicity at the range of concentration (1-250 ${\mu}g/m{\ell}$) on the human fibroblast cell (hFCs). KSMT decreased the production of reactive oxygen species (ROS) and DPPH generation depending on the concentration. KSMT significantly inhibited angiotensin converting enzyme(ACE) activity depending on the concentration compared with control. KSMT maintained body weight of body, heat and kidney nearly normal group in hypertensive rat induced by DOCA-salt. KSMT significantly blood pressure and heart beat rate compared with control in hypertensive rat induced by DOCA-salt. KSMT significantly decreased aldosterone, dopamine, norepineph- rine, epinephrine compared with control in hypertensive rat induced by DOCA-salt. KSMT significantly decreased the level of potassium and cloride compared with control wheareas increased that of calcium significantly in hypertensive rat induced by DOCA-salt. KSMT significantly decreased the level of uric acid and BUN compared with control in hypertensive rat induced by DOCA-salt. It is verified experimentally tat Kamisamultang(KMST) which has been used broadly as a clinical therapeutics in oriental medicine is effective for anti-hypertension mechanism. And it could be applied to develope the reliable prescriptions for anti-hypertension in the future.

The garlic has been eaten widely regardless of easten and westen countries to cure the various disease like cancer, tuberculosis, dentalgia, toxemia and leprosy from ancient times. Even now it is reported that they lower the level of triglycerides and cholesterol in blood and that they also affect on the cohesive power of the platelets. In addition, it is also known that it lowers the glucose level in blood. Especially, the sulfur containing amine acid and the derivatives of the garlic has the counteracting effect to heavy metals. Nowadays, the garlic is known for its efficiency for the various kinds of cancer, neoplasms, hypertension, arteriosclerosis and apoplexy. However, it is reported that the intake of the excessive amount of garlic causes hemolytic anemia recently. The hemolytic anemia is more severe especially in HK phenotype dogs which has Na-K-ATPase activity. Therefore, this study was performed to examine the effect on the blood of the HK phenotype Jindo dogs when administered the excessive amount of garlic. HK phenotype group showed the significant decrease on RBC, WBC, PCV, Hb, MCV, MCHC, GSH, Met-Hb but LK phenotype group didn's show the significant decrease. AST, ALT, BUN, creatinine, CPK, glucose, and total protein values were within normal ranges during the period.

현대사회는 생활습관, 공해, 오염, 독성물질 등 여러 종류의 산화스트레스를 받는 환경에 노출되어 있으며, 이런 산화스트레스들은 인간에게 있어 여러 질병을 야기한다는 많은 증거 들이 나오고 있다. Ferric Nitrilotriacetate (Fe-NTA)는 iron-induced oxidative Stress로 인해 신장독성에 관여되어 있다고 보고된 물질이다. 이에 본 연구진은 랫드에 항산화 효과가 있는 차전초(Plantago asiatica) 추출물을 투여하고 Fe-NTA를 복강 주사하여 선장에서 iron-induced oxidative stress를 유발한 후, 산화스트레스를 얼마나 억제하여 주는 지를 혈액에서 신장기능 지표인 blood urea nitrogen (BUN)과 creatinine (Cr)을 측정하고, 신장조직에서는 항산화 바이오마커들인 reduced glutathione (GSH), glutathione-S-transferase (GST), glutathione reductase (GR) 및 지질과산화물 (lipid peroxide)인 malondialdehyde (MDA)를 측정 하였다. 신장기능 이상시 증가되는 BUN 및 Cr은 Fe-NTA에 의해 산화스트레스만 유발한 그룹에서는 $116.82{\pm}5.20$ mg/dL과 $2.70{\pm}0.20$ mg/dL로 아무것도 처리하지 않은 대조군의 $18.54{\pm}1.29$ mg/dL, $0.52{\pm}0.04$ mg/dL에 비해 약 6.3배 및 5.2배의 증가를 나타냈다. 반면 차전초를 투여한 1g/kg b.w. 군에 서 BUN 및 Cr의 활성 이 각각 $95.76{\pm}7.89$ mg/dL과 $2.16{\pm}0.340$ mg/dL, 2g/kg b.w. 군에서는 $89.34{\pm}26.93$ mg/dL 과 $2.20{\pm}0.51$ mg/dL, 4 g/kg b.w. 군에서는 $39.54{\pm}21.93$ mg/dL과 $1.16{\pm}0.55$ mg/dL으로 농도 의존적으로 유의적 (p < 0.05) 차이를 보이며 감소하는 결과를 보였다. 항산화의 바이오마커로 작용하는 GSH, GST 및 GR은 Fe-NTA에 의해 산화스트레스만 유발한 그룹에서는 각각 $59.45{\pm}12.32$ mmol GSH/g tissue, $49.88{\pm}4.55$ Units/g tissue, $56.70{\pm}5.40$ Units/g tissue로 아무것도 처리하지 않은 정상그룹의 $142.82{\pm}16.51$ mmol GSH/g tissue, $124.69{\pm}13.073$ Units/g tissue, $107.31{\pm}8.70$ Units/g tissue에 비해 58.4%, 60.0%, 47.2%로 현저하게 감소하였다. 반면 차전초 추출물을 1, 2, 4 g/kg b.w. 으로 투여한 그룹에서의 GSH는 $77.86{\pm}12.62$, $123.11{\pm}12.72$, $147.97{\pm}26.27$ mmol GSH/g tissue로 Fe-NTA만 처리한 그룹에 비해 약 1.3배, 2.1배, 2.5배 증가하였으며, GST는 $66.59{\pm}5.01$, $83.25{\pm}8.38$, $124.68{\pm}13.67$ Units/g tissue.로1.3배,1.7배, 2.5배 증가, GR은 $67.37{\pm}8.66$, $80.34{\pm}6.06$, $98.67{\pm}10.11$ Units/g tissue로 1.2배, 1.4배, 1.7배 증가하였다. 산화스트레스로 유발되는 지질과산화물을 신장에서 측정 하였을 때 Fe-NTA에 의해 산화스트레스만 유발한 그룹은 $215.70{\pm}49.73\;{\mu}mol$/g tissue로 대조군 그룹의 $46.20{\pm}10.65\;{\mu}mol$/g tissue보다 지질과산화를 많이 일으켜 4.7배 많은 MDA를 생성한 것을 나타냈지만, 차전초 추출물 1, 2,4 g/kg b.w. 투여한 그룹은 MDA의 생성량이 $141.74{\pm}10.79$, $116.11{\pm}9.19$, $86.52{\pm}22.30\;{\mu}mol$/g tissue로 약 34.3%, 46.2%, 59.9% 감소한 것을 확인하였다. 신장에서 iron-induced oxidative stress에 의해 독성을 유발하는 Fe-NTA를 처리 하였을시 신장손상 지표인 BUN과 Cr은 증가하고, 항산화 지표인 GSH와 GST, GR은 감소함과 동시에 지질과산 화물인 MDA는 증가하였다. 그러나 차전초 추출물을 농도를 달리하여 투여한 후 Fe-NTA로 산화스트레스를 유발한 그룹은 농도 의존적으로 BUN과 Cr은 감소하고, 항산화 지표들은 증가함과 동시에 MDA는 감소하는 경향을 보였으며 Fe-NTA만 처리한 그룹과 유의적 차이를 보였다. 위 결과들을 종합하면 Fe-NTA는 산화스트레스에 의해 신장에 심각한 손상을 줄 수 있으며, 차전초 추출물은 항산화 효과를 바탕으로 하여 Fe-NTA에 의한 신장 손상에 대한 보호 또는 개선 효과가 있음을 확인 하였다.

Objective: This experiment was conducted to evaluate the effects of different levels of dietary crude protein (CP) on growth performance, blood profiles, diarrhea incidence, nutrient digestibility, and odor emission in weaning pigs. Methods: A total of 240 weaning ([Yorkshire×Landrace]×Duroc) pigs (8.25±0.050 kg body weight [BW]) were assigned to six treatments based on sex and initial BW, with five replicates of eight pigs per pen in a randomized complete block design. Experimental diets with different crude protein levels for early and late weaning phases were as follows: i) CP16, corn-soybean-based diet containing 16%/15% CP; ii) CP17, corn-soybean-based diet containing 17%/16% CP; iii) CP18, corn-soybean-based diet containing 18%/17% CP; iv) CP19, corn-soybean-based diet containing 19%/18% CP; v) CP20, corn-soybean-based diet containing 20%/19% CP; and vi) CP21, corn-soybean-based diet containing 21%/20% CP. Results: In the early weaning period, average daily feed intake increased when the dietary CP level decreased (linear, p<0.05). During the entire experimental period, average daily gain and the gain to feed ratio decreased when the dietary CP level increased (linear, p<0.01). Additionally, a decrease in dietary CP level resulted in a linear increase in final BW (linear, p<0.05). In the early and late weaning periods, blood urea nitrogen (BUN) decreased when the dietary CP level decreased (linear, p<0.01). There were no significant differences in creatinine, glucose, total protein, triglyceride or insulin-like factor-1 levels over the experimental period. The concentrations of immunoglobulin A (IgA) and IgG were not significantly affected by dietary CP levels during the experimental period. In the early weaning period, fecal and urine N decreased when the dietary CP level decreased (linear, p<0.01). No differences in nutrient digestibility among the treatments during the early weaning period were found. Throughout the whole experimental period, when the dietary CP level decreased in the weaning pig diet, the diarrhea incidence decreased linearly (linear, p<0.01). Throughout the whole experimental period, when the dietary CP level decreased in the weaning pig diet, ammonia, amines and hydrogen sulfide decreased linearly (linear, p<0.01). Conclusion: Reducing dietary CP could decrease diarrhea incidence, the concentration of BUN in serum and odor emission in manure. Furthermore, it could improve N excretion in feces and urine and growth performance in weaning pigs.

This study was conducted to investigate changes of blood metabolites and enzyme activities at different slaughter ages of Hanwoo cattle. Blood samples were taken from six hundred thirty two steers (24~33 months of age) and one hundred twenty eight bulls (17~24 months of age) by venipuncture from caudal vein immediately prior to slaughter. Glucose concentrations were linearly increased (P<0.001) with increases of the slaughter age in steers, and blood urea nitrogen (BUN) concentrations were linearly decreased (P<0.001) with increases of the slaughter age in steers. Likewise, glucose and albumin concentrations in bulls were linearly decreased (P=0.009 and P<0.001, respectively) with increases of the slaughter age. BUN, cholesterol, triglycerides, and total cholesterol concentrations were linearly increased (P<0.001, 0.018 and 0.002, respectively), and creatinine concentrations were quadratically increased (P=0.009) with increases of the slaughter age. Activity of gamma glutamyltransferase (${\gamma}$-GT) and aspartate aminotransferase (AST) was linearly increased (P<0.001) with increases of the slaughter age in both steers and bulls, whereas alanine aminotransferase (ALT) was not affected by increasing slaughter age. In addition, the concentrations of ${\gamma}$-GT and AST were higher (P<0.05) for bulls than those of steers at 24 months of age. Increased levels of ${\gamma}$-GT and AST indicate impaired liver function; it may be associated with increases of concentrate level which is a concomitant of the extended fattening periods in Hanwoo feeding. In conclusion, the results in the present study may be one of the useful information for diagnosis of the metabolic disorder in Hanwoo cattle.
