Objective: In the present study, we examined whether the post-prandial reduction in plasma growth hormone (GH) levels is related to the increase in plasma insulin levels in ruminants. Methods: We performed two experiments: intravenous bolus injection of insulin (0.2 IU/kg body weight) or glucose (1.0 mmol/kg body weight) was administered to increase the plasma insulin levels in male Shiba goats. Results: In the insulin injection experiment, significant (p<0.05) increase in GH concentrations was observed, 15 to 20 min after the injection; it was accompanied with a significant (p<0.01) increase in cortisol concentrations at 45 to 90 min, when compared to the concentrations in the saline-injected controls. The glucose injection significantly (p<0.05) increased the plasma GH concentration at 20 to 45 min; this was not accompanied by significantly higher cortisol concentrations than were observed for the saline-injected control. Hypoglycemia induced by the insulin injection, which causes the excitation of the adrenal cortex, might be involved in the increase in insulin levels. Conclusion: Based on these results, we conclude that post-prandial increases in plasma insulin or glucose levels do not induce a decrease in GH concentration after feeding in the ruminants.

Background: The aim of this study was to evaluate the efficacy and tolerability of a gemcitabine, 5-fluorouracil and leucovorin (GEMFUFOL) chemotherapy regimen as first line treatment of metastatic biliary tract cancer. Materials and Methods: All patients received folinic acid $400mg/m^2$ on day 1, 5-fluorouracil bolus $400mg/m^2$ on day 1, IV infusion of 5-fluorouracil $2400mg/m^2$ over 46 hours, and gemcitabine $1250mg/m^2$ on day 1. Results: A total of 29 patients with metastatic biliary tract cancer received GEMFUFOL regimen as the firstline treatment. The mean follow-up was 22.1 months (95%CI, 12.5-31.8). One patient (3.4%) achieved complete response, 5 (17.2%) had partial response, and 4 (13.8%) had stable disease. The median progression-free survival was 3.3 months (95%CI, 2.9-3.7), and the median overall survival was 8.8 months (95%CI, 3.5-14). The 1-year and 2-year survival rates were 58.6% and 30%, respectively. Grade 3 and 4 toxicity included neutropenia in 4 patients (13.7%), thrombocytopenia in 2 (6.8%), anemia2 (6.8%), and alopecia in 1 (3.4%). Two patients (6.8%) developed febrile neutropenia. A dose reduction was achieved in 8 patients (27.6%) while 5 patients had extended-interval dosage (17.2%) for toxicity. Conclusions: The GEMFUFOL chemotherapy regimen was generally efficacious and tolerable as a first-line treatment of metastatic biliary tract cancer.

We performed a study of epidural patient controlled analgesia of meperidine with or without 0.08% bupivacaine for 48 hours after Cesarean section. 51 parturients were randomly assigned to one of two treatment groups : 1) epidural 0.2% meperidine group(n:24) and 2) epidural combined group with 0.2% meperidine and 0.08% bupivacaine(n:27). All parturients used patient controlled analgesia with loading dose, 2 ml/hour continuous infusion, 1 ml bolus infusion and lockout time, 8 minutes. visual analog scales after loading doses were not significantly different in either groups. The total quantity of meperidine consumption and hourly consumption were significantly lower in the combined group than meperidine group(P<0.05). The cumulative amount of meperidine consumption were also significantly lower in the combined group than meperidine group at 6, 12, 24 and 48 hours. In combined group the hourly consumption of meperidien from 3 hours to 12 hours after loading dose was significantly lower than those of meperidine group. Above 90% of parturients were satisfied in both groups. Side effects were: numbness (2), thigh weakness (1), nausea (1), headache (1) and back pain (2) in epidural meperidine group. There were no case needed specific treatment in both groups. We conclude that analgesic effects were similar in both groups, however the amount of meperidine consumption was less for meperiding group than combined group.

The analgesic efficacy and side-effects of combined continuous epidural infusion of bupivacaine and morphine, in comparison with intramuscular (IM) administration of narcotics, for postoperative pain relief after cesarean section and hysterectomy were evaluated. We divided 60 patients into 4 groups randomly. IM (meperidine) group after cesarean section (Group 1, n = 20); Continuous epidural group after cesarean section (Group 2, n=20); IM (meperidine) group after hysterectomy (Group 3, n=10); Continuous epidural group after hysterectomy (Group 4, n=10). Following each operation, the epidural groups had an epidural catheter placed ($L_{2{\sim}3}$ or $L_{3{\sim}4}$), and a bolus of 1.5mg of morphine was injected, and followed by continuous infusion of 0.3% bupivacaine 2ml/hour and morphine 2.5mg/day for 48 hours. The IM groups had received meperidine 50mg IM injection every 4 hours as needed. We evaluated analgesic efficacy with VAS (visual analogue scale) at 1, 2, 24, 48, and 72 hours after operation. The side-effects (nausea &, vomiting, respiratory depression, pruritus and urinary retention) were evaluated with 4 points scale at day 1, 2, and 3 after operation. The results were as follows 1) The continuous epidural (bupivacaine+morphine) groups were superior to the IM (meperidine) groups with respect to postoperative analgesia at 1, 2, and 24 hours after cesarean section, and at 1, 2, 24, and 48 hours after hysterectomy. 2) Vomiting were more frequent in the epidural groups 2 days after cesarean section. 3) Pruritus was more frequent in the epidural groups 1 and 2 days after cesarean section.

Background: Epidural analgesia has been widely used for postoperative pain relief. However, it is not known which regimen provides the best result due to many variety. The aim of this study is to evaluate the analgesia and side effects of epidural mixute of fentanyl, bupivacaine and clonidine, as one kind of regimen. Methods: One hundred adult patients scheduled for upper abdominal surgery under general anesthesia were evaluated. Epidural catheterization was done after operation. A bolus, 0.1% bupivacaine 10 ml containing fentanlyl 100 ${\mu}g$, was administered and followed up with continuous infusion of mixture of fntanyl 600 ${\mu}g$, 0.5% bupivacaine 20ml and clonidine 150 ${\mu}g$ at a rate of 2ml/hr for 50 hours. Analgesia was assessed using VAS, PHS and PRS. Side effects and number of patients who took additional analgesics were evalutated. Plasma samples were obtained to determine fentanyl concentration. Results: After the administrations of drugs, patients pain scores decreased notably, and pain relief scores increased significantly. Minimum side effects were noted. Twenty-one patients required additional analgesics. Plasma concentration of fentanyl was 0.07~0.14 ng/ml. Conclusion: Epidural infusion of mixture of fentanyl, bupivacaine and clonidine is an effective regimen for postoperative pain relief after upper abdominal surgery.

The purpose of this study is to compare the postoperative analgesic effect of morphine and meperidine, employing intravenous patient controlled analgesia after cesarean section. Among fifty nine parturients undergoing cesarean section with general anesthesia, 32 were administered morphine designated as 'morphine group', and 27 parturient administered meperidine as 'meperidine' group, during 48 hours after commencement of PCA. Doses administered, based on potency for this setting, were equivalent to 1 mg morphine or 10 mg meperidine. Loading dose was administered when parturient first complained of pain after cesarean section. This was followed with bolus dose, 1 mg for morphine group and 10 mg for meperidine group, with a lockout interval of 8 minutes between doses wherever parturient requested additional analgesia. Visual analog scale(VAS) pain scores during rest were significantly lower at only 1 and 2 hour for the meperidine group, than morphine group. Loading dose and cumulative dose at 1, 2 and 3 hours were significantly lower for meperidine group than the morphine group. There were no significant difference in total dose and hourly dose for 48 hours and cumulative dose at 6, 12, 24, and 48 hours between both groups. More than 90% of the parturients from both groups were satisfied with the analgesic effects of pain relief. Morphine group experienced side effects such as: pruritus, sedation and dizziness. Meperidine group had sedation, dizziness, nausea and local irritation. Neither group required any specific treatment for any of the above side effects. We conclude that meperidine had greater analgesic effect at early stage of post-operative period.

An experiment was carried out to investigate the effect of change in length of hay offered on eating and rumination behaviour in sheep using three types of hay diets (L: long, M: 8.0-cm cut, S: 1.2-cm cut) and 3 Japanese Corriedale wethers, and the experiment was designed as $3{\times}3$ latine square. The time spent eating per 100 g hay was significantly shorter with long (L) hay (p < 0.05) than with chopped (M and S) hay, and therefore, the eating rate (g D.M./min.) was significantly higher in the former (p < 0.05) than in the latter. Rumination appearance (the lag time after eating) tended to be longer with long hay than with chopped hay, but not significantly (p > 0.05). Daily time spent ruminating, the actual chewing time and daily number of chews tended to be more in feeding long hay than in feeding chopped hay, but not significantly. Daily number of rumination periods was significantly more with long hay (p < 0.01) than with chopped hay. Cyclic rate tended to be longer with long hay than with chopped hay, in particular, the difference in values between long hay and 8.0-cm cut hay was significant statistically (p < 0.01). The rumination index (time spent ruminating/100 g D.M, eaten) tended to be higher with long hay than with chopped hay, and the difference in values between long hay and 1.2-cm cut hay was significant statistically (p < 0.05). Bolus time was significantly longer with long hay (p < 0.01) than that with 8.0-cm cut hay. The circadian pattern of ruminating time was not changed by the changes in length of hay eaten.

Among the 63 patients with histopathologically proven primary squamous cell anal cancer who were managed in Presbyterian Medical Center and Yonsei University Cancer from Jan. 1971 to Dec. 1991, 34 patients, who were managed with surgery alone(abdominoperineal resection) or post-operative radiotherapy and concurrent chemoradiotherapy were analysed. With mean follow up time of 81.3 months, 30 Patients(88$ \% $) were followed up from 17 to 243 months. In methods, 10 patients were treated with surgery alone. 9 Patients were treated with combined surgery and postoperative radiotherapy(50$\∼$60 Gy in 28$\∼$30 fractions). 15 patients were treated with concurrent chemoradiotherapy. Chemotherapy (Mitomycin C 15 mg/squ, bolus injection day 1;5-FU, 750 mg/squ, 24hr infusion, day 1 to 5) and radiotherapy started the same day. A dose of 30 Gy was given to the tumor and to the pelvis including inguinal nodes, in 15 fractions. After 2 weeks a boost of radiotherapy(20 Gy) to the ano-perineal area and second cycle of chemotherapy completed the treatment. The overall 5-year survival rate was 56.2$ \% $. Concurrent chemoradiotherapy group was 70$ \% $ and surgery alone group was 16.7$ \% $. According to the cox proportional harzard model, there was significant difference between survival with concurrent chemoradiotherapy and surgery alone(p=0.0129), but post-operative radiotherapy was 64.8$ \% $, which was not stastically significant(p=0.1412). In concurrent chemoradiotherapy group, the anal funtion Preservation rate was 87$ \% $ and the severe complication rate(grade 3 stenosis and incontinence) was 13.3$ \% $. In conclusion, we conclude that the concurrent chemoradiotherapy may be effective treatment modality in patients with anal cancer.

Brain drug targeting through the blood-brain barrier (BBB) in vivo is possible with peptidornirnetic monoclonal antibodies that undergo receptor-mediated transcytosis through the BBB. Monoclonal antibody to the rat transferrin receptor, such as the OX26 was studied in rats as a transport vector through BBB on the transferrin receptor. But, OX26 is not an effective brain delivery vector in mouse. In the present studies, rat monoclonal antibody, 8D3 to the mouse transferrin receptor were evaluated for brain drug targeting vector intransgenic mouse model. Pharrnacokinetic parameters in plasma and organ uptakes were determined at varioustimes after i.v. bolus injection of [$^{}125}I$] 8D3 in Balb/c mice. Brain uptake of [$^{}125}I$] 8D3 was also studied with an internal carotid artery perfusioncapillary depletion method. After i.v. injection of [$^{}125}I$] 8D3, plasma concentrations declined biexponentially with elimination half lift of approximately 2.2 hours. Brain uptake of [$^{}125}I$] 8D3 was $0.50{\pm}0.09$ persent of injected dose per g brain after 2 hours i.v. injection. After perfusion 5 min the apparent volume of distibution of [$^{}125}I$] 8D3 in brain was $22.3 {\mu}l/g,$ which was 4.8 fold higher than the intravascular volume. These studies indicate rat monoclonal antibody to the mouse transferrin receptor, 8D3 may be used for brain drug targeting vector in mice.
