돼지에서 신장의 허혈-재관류 손상의 감소에 대한 비타민 C와 E의 영향을 알아보기 위하여 본 연구를 실시하였다. 돼지 10두를 2개의 군으로 구분하여, 60분 동안 체온과 같은 허혈을 한쪽 신장에 유발하고 반대쪽 신장은 절제하였다. 처치군은 수술 2일전 비타민 C와 E를 이틀 동안 전처치하고, 그 뒤에 수술 중 비타민 C와 heparin이 첨가된 생리식염수를 관주-흡인하였다. 대조군은 heparin이 첨가된 생리식염수의 관주-흡인만을 하였다. Blood urea nitrogen, creatinine 및 antioxidant superoxide dismutase (SOD)를 측정하기 위하여 수술 전, 수술 후 1, 3, 7, 14일에 혈액 샘플을 채취하였다. 수술 후 14일에 안락사를 시키고, 병리조직검사를 위하여 신장을 적출하였다. BUN은 대조군과 처치군 사이에 수술 후 1일, 3일 또는 7일에 유의성이 있는 차이가 인정되었다. (p<0.05). Creatinine은 대조군과 처치군 사이에 수술 후 3일에 유의성이 있는 차이가 인정되었다. (p<0.05). 혈장에서의 항산화 효소의 활성은 대조군과 처치군 사이에서 수술 후 14일에 유의성이 있는 차이가 인정되었다. (p<0.05). 병리조직 검사 결과에서 처치군이 대조군 보다 더 적은 신장 세뇨관에서의 손상의 정도를 보였다. 비타민 C와 E는 돼지에서 신장의 허혈-재관류 손상을 감소시켰다.

The pharmacokinetics of carbamazepine(100 mg/kg, oral) in the folic acid-induced renal failure rabbits was studied. Renal failure was induced by the i.v. injection of folic acid (50, 100, and 200 mg/kg). At folic acid dose of 100 and 200 mg/kg, the serum creatinine concentration (Scr) and blood urea nitrogen (BUN) increased significantly compared with control rabbits. Plasma concentrations and area under the plasma level-time curve (AUC) of carbamazepine increased significantly at folic acid dose of 100 and 200 mg/kg. The elimination rate constant (Kel) of carbamazepine decreased significantly, and half-life $(t_{1/2})$ of carbamazepine increased significantly at folic acid dose of 100 and 200 mg/kg. The serum creatinine concentration (Scr) correlated well with AUC and elimination rate constant (Kel) of carbamazepine, as well as BUN with AUC and elimination rate constant (Kel) of carbamazepine. These results suggest that adjustment of the dosage regimen of carbamazepine is desirable, and serum creatinine concentration (Scr) as well as BUN can be used for adjusting the dosage regimen of carbamazepine in renal failure.

A 12-year old neutered male Yorkshire terrier dog was presented to the Veterinary Medical Teaching Hospital of Seoul National University with a history of chronic intermittent diarrhea, vomiting, anorexia and weight loss of 2-months duration. On presentation, he was very cachexic and had ascites. Abnormal findings on a complete blood count and chemistry profile included mild anemia, leukocytosis, panhypoproteinemia, hypocholesterolemia, decreased blood urea nitrogen (BUN) and increased serum bile acids. Radiographic findings indicated microhepatica. Peritoneal fluid analysis was consistent with transudates (total protein < 2.5 g/dl, total nucleated cell count = 2,200/ul) and cytologic examination of the fluid revealed neoplastic lymphoblasts. From these findings hepatic dysfunction and protein-losing enteropathy were attributable to abdominal lymphoma. This case suggests that cytologic examination is important in diagnosing underlying diseases of ascites, even if it is transudative effusion.

The protective effects of Phaleria macrocarpa (PM) against oxidative stress in diabetic rats were investigated. Diabetes was induced in male Sprague Dawley rats using alloxan (150 mg/kg i.p). After the administration of PM fractions for two weeks the diabetic symptoms, nephropathy and renal antioxidant enzymes were evaluated. The results showed that the oral PM treatments reduced blood glucose levels in diabetic rats. The PM fractions decreased kidney hypertrophy and diminished blood urea nitrogen (BUN) in diabetic rats. Malondialdehyde (MDA), a lipid peroxidation marker, was increased in diabetic animals, but was suppressed by the PM treatments. In addition, the superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) activities, and glutathione (GSH) level in the alloxan-induced diabetic rats were significantly decreased compared with those in the normal rats, but were restored by PM treatments. The PM fractions also suppressed the level of MDA in the kidney. In conclusion, the anti hyperglycemic and anti-nephropathy of P. macrocarpa may be correlated to the increased renal antioxidant enzyme activity in the kidney.

Toxic effects of a mushroom, Amanita volvata, were studied in respect to biochemical and histological changes induced in the liver and kidneys of mice. The changes in biochemical parameters characteristically appeared 12 hrs after oral administration of an aqueous extract of the mushroom. The hepatic glycogen decreased markedly to 17% of the control level and a concemitant decrease in blood glucose was also observed. The activity of serum glutamic oxaloacetic transaminase (SGOT) was elevated by 2.5-fold and the level of blood urea nitrogen (BUN) increased by 3-fold, respectively, 12 hrs after administration of the mushroom, their levels being maintained up to 24 hrs.

Many chemotherapeutic drugs were developed and contributed to the increase of cure rate of cancer, however severe side effect of these drugs is a major cause of poor quality of life of cancer patients. Effect of deer blood on cancer therapy was investigated in mouse tumor model. Deer blood itself was shown to have mild antitumor activity. However it has significant effect on the reduction of the side effects of chemotherapy. Deer blood recovered the reduction of WBC and platelet (myelotoxicity) during fluorouracil chemotherapy. Deer blood also recovered the increase of serum blood urea nitrogen (BUN; indicator of renal toxicity) and increase of serum amylase activity (AMY; indicator of pancreatic toxicity) almost to the control level during cisplatin chemotherapy. Fluorouracil and cisplatin are major chemotherapeutic drugs which are currently used in clinical cancer therapy, and the results strongly suggest that deer blood can be used for reducing the side effects and improving the quality of life during chemotherapy of cancer patients.

Objective: This experiment was conducted to investigate the influence of rapeseed meal (RSM) supplementation in weaning pig diet on growth performance, blood profile, carcass characteristics and economic analysis on weaning to finishing pigs. Methods: A total of 120 cross bred ([Yorkshire${\times}$Landrace]${\times}$Duroc) weaning pigs were allotted to 5 treatments in a randomized complete block design. Each treatment had 4 replications with 6 pigs per pen. Five different levels of RSM (0%, 2%, 4%, 6%, and 8%) were used as dietary treatments. Results: Overall, no treatment showed significant differences in growth performance with increased dietary RSM levels. The concentration of blood urea nitrogen (BUN) decreased as dietary RSM levels increased in 6 weeks (linear response, p<0.01). Total cholesterol, high density lipoprotein cholesterol, low density lipoprotein cholesterol, triiodothyronine, and thyroxine showed no significant differences, neither were there any significant differences in the immune response (IgG and IgA). As the dietary RSM levels of weaning pig diet were increased, no differences were found among dietary treatments upon performing proximate analyses of the pork after finishing. The influence of RSM supplementation on nutrient digestibility and nitrogen retention were not affected by dietary RSM levels either. With increased dietary RSM levels in the weaning pig diet, no differences among dietary treatments were found after performing proximate analyses of the pork's physiochemical properties. In addition, there were no significant differences observed in pork colors, pH levels, and economic benefits. Conclusion: Consequently, this experiment demonstrated that weaning pig's diet containing RSM influenced BUN concentration, but there were no detrimental effects on the growth performance of weaning pigs with up to 8% RSM in the diet.

In order to investigate the effect of recombinant bovine somatotropin (rbST) on blood metabolites and milk yield of lactating buffaloes, 30 lactating buffaloes after acclimatization for 30 days were divided into 2 groups as control (n=10) and experimental (n=20). Animals were injected 250mg of rbST (Boostin-250) on 0, $14^{th}$ and $28^{th}$ day subcutaneously at ischiorectal fosse, where as control animals were given placebo of 2 ml normal saline. Fortnightly blood samples were collected from 15 days prior to 60 days post injection to estimate different blood metabolites. Daily milk yield was recorded and weekly average yield of each animal was calculated. From this study, it was found that blood metabolites such as glucose, triglycerides, total proteins, albumin, globulin and electrolytes like sodium and potassium were not altered by rbST injection. However, there was a significant (p<0.05) decrease in blood urea nitrogen (BUN) concentration in experimental group as compared to that of control group. The weekly average milk yield was significantly (p<0.001) higher (25%) in rbST injected group over the control group.
