  • This study was to investigate the effects of ascorbic acid and alpha-tocopherol on the attenuation of renal ischemia-reperfusion (IR) injury in pigs. Ten pigs were subjected to 60 minutes of warm unilateral renal ischemia followed by removal of contralateral kidney and then divided into two groups. Treatment group was performed ascorbic acid and alpha-tocopherol pretreatment 2 days before operation and ascorbic acid with heparin-saline solution irrigation-aspiration. Otherwise, control group used only irrigation-aspiration of heparin-saline solution. Blood samples were collected from these pigs for measurement of serum blood urea nitrogen (BUN) and creatinine values, antioxidant superoxide dismutase (SOD) at pre, day 1, day 3, day 7 and day 14. The kidneys were taken for histopathologic evaluation after euthanasia on postoperative day 14. The levels of BUN were significantly increased in the control group on day 1, day 3 and day 7 (P<0.05). And the level of creatinine was significantly increased in the control group on day 3 (p<0.05). Activity of antioxidant enzymes in plasma revealed significant difference (p<0.05) between control and treatment group at day 14. In histopathologic findings, treatment group was showed less damage than that of control group on the basis of renal tubular damage. It was concluded that ascorbic acid and alpha-tocopherol attenuated renal I/R injury in the pigs.

  • 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.

  • 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.

Methods : We injected a vein with 65mg/kg of streptozotocin(STZ) on the rats. And then administered Sedang-hwan; 18.7mg/kg/day to sample groups and observed the weight and glucose level, insulin, C-peptide, triglyceride, albumin, T-protein, BUN(Blood Urea Nitrogen) and creatinine in blood. Results : 1. The sample groups showed a high suppressive effect of weight loss(P=0.002). 2. The sample groups' glucose level showed a effective in lowering level(P=0.001). 3. The sample groups showed a higher insulin level than control groups. 4. The sample groups showed a higher C-peptide level than control groups(P=0.001). 5. The sample groups' triglyceride level showed a effective in lowering level. 6. The sample groups showed a higher HDL-cholesterol level than control groups(P<0.001). 7. The sample groups showed a higher T-protein level than control groups(P=0.04). 8. The sample groups showed a higher albumin level than control groups(P<0.001). 9. The sample groups' creatinine level showed a effective in lowering level(P=0.04). 10. The sample groups' BUN level showed a effective in lowering level(P=0.03). Conclusions : Conclusively, Sedang-hwan was recognized to have decrease effect of serum glucose, triglyceride, creatinine, BUN of the diabetic rats induced by streptozotocin. It was suggested that Sedang-hwan can be used for effective diabetes mellitus medical treatment. It is also required to study further about detailed principles of blood-sugar dropping effect by Sedang-hwan, and recovery by diabetes mellitus.
