Background: Although the use of intravenous patient controlled analgesia (IVPCA) has been compared to the use of patient conrolled epidural analgesia (PCEA), there is no optimal administration route of alfentanil for the treatment of postoperative pain. This randomized double-blind study compared the efficacy of the use of IVPCA and PCEA for postoperative pain and the side effects after a total abdominal hysterectomy (TAH). Methods: Sixty patients undergoing a TAH were randomly assigned to receive either IVPCA (Group I) or PCEA (Group E) for the infusion of alfentanil for postoperative pain control. In both groups, a loading dose of $750{\mu}g$ alfentanil was administered. All patients received the same continuous infusion rate (0.3 mg/h), bolus dose (0.15 mg), and lockout time (15 min). The incidence of side effects, the VAS (visual analog scale) of pain, blood pressure, and heart rate were checked for 20 hours after the loading dose injection. Results: The VAS of pain was not significantly different between the two groups of patients. The onset of the analgesic effect was significantly more rapid in the Group I patients than in the Group E patients. There was no difference in side effects for either group. Conclusions: When considering multiple factors such as the onset of analgesia, technical difficulties or infection after the procedure, IVPCA using alfentanil is more useful than PCEA for postoperative pain control after a TAH.

STZ투여 전후 2주씩 4주간의 규칙적인 운동 부하가 당뇨흰쥐의 골격근 당섭취와 당내성에 미치는 영향을 알아보기 위하여 Sprague-Dawley종 수컷 흰쥐를 사용하여 soleus근의 당섭취를 시험관에서 $^3H$-3-O-methyl-glucose의 섭취로 추적하였으며 정맥으로 당을 부하 (0.5g/kg BW)하여 당내성을 평가한 본 실험의 결과를 요약하면 다음과 같다. STZ의 투여로 대조군에 비하여 공복시 혈당과 유리지방산이 증가하고 인슐린 농도, soleus근의 당섭취, 인슐린에 대한 예민도와 반응도, 및 근 glycogen농도는 감소하였으며 내당능이 저하하였다. STZ 투여 흰쥐에서 4주간의 규칙적인 운동으로 인한 변화로 안정군에 비하여 공복시 혈당이 감소하고 soleus근의 당섭취와 인슐린에 대한 반응도 및 근glycogen 의 농도가 증가하였으며 유리지방산의 농도가 감소하는 경향을 보였다. 그러나 인슐린 농도는 차이가 없었으며 당내성은 개선되지 않았다. 위의 결과로 보아 4주간의 운동은 STZ 투여후 당뇨 흰쥐 발생율에는 영향을 미치지 못하였으나 골격근의 인슐린 반응도는 향상시켰으며 공복시 혈당도 감소시키는 효과를 나타내었다. 그러나 저하된 내당능은 골격근의 인슐린 반응도가 향상되었음에도 불구하고 개선되지않은 것으로 사료된다.

Ulcerative colitis (UC) is characterized by a life-long chronic course with remissions and exacerbations. Use of biological therapies may reduce or delay the surgical procedures in patients with UC. The aim of this study was to determine the impact of infliximab (IFX) use on the rate of remission, surgical interventions, and the effect on quality of life in patients with moderate to severe UC. Literature was searched for studies that investigated the efficacy of IFX on the rate of remission, colectomy and quality of life (QoL) between January 1990 and June 2012 at MEDLINE, January 1988 and June 2012 at EMbase and others. Eleven trials were included in the meta-analysis; divided into placebo controlled 8 trials and intravenous corticosteroid controlled group 3 trials. In comparison to placebo control groups, patients who received IFX had an odds ratio (OR) of 3.712 (95% CI: 2.714, 5.079) for the short-term clinical remission, and 3.053 (95% CI: 2.044, 4.559) for the rate of long-term remission. In colectomy rate and quality of life (QoL), odds ratio were 0.566(95% CI: 0.387, 0.827) and 0.658 (0.505, 0.811) respectively. Any adverse reactions including infections, infusion reaction, rash and arthralgia were equivalent in both groups. Compared with intravenous corticosteroid controlled group, patients who received IFX had lower remission rate with short-term odds ratio 0.227 (95% CI: 0.033, 1.556) and long-term odds ratio 1.054 (95% CI: 0.317, 3.502) respectively. However, statistical significance was not showed with both two analyses. The higher adverse drug reaction (ADR) rates were occurred in the corticosteroid controlled groups. 73.3% of patients treated corticosteroid reported Cushing-like syndrome with moon face. In conclusion, IFX does increase remission rate and decrease the rate of colectomy in patients with UC without elevating any adverse reactions significantly. IFX also improves QoL in moderate to severe UC patients. It would not exceed the efficacy of intravenous corticosteroid, whereas intravenous corticosteroid also reported high rate of adverse reactions.

This study was carried out to observe the direct effect of hydrocortisone on renal function by infusing it into a renal artery. Hydrocortisone (5mg/kg) or saline (0.5 ml/kg) was infused directly into the left renal artery of the rabbit, the right kidney was left intact to serve as a control for general action of acetazolamide (10 mg/kg) or aminophylline (10 mg/kg), which was administered intravenously 30 minutes after the direct infusion of pretreated drugs (hydrocortisone or saline). The changes of urine volume, pH, urinary excretion rates of $Na^+,\;K^+\;and\;Cl^-$, and the clearances of inulin and PAH were measured at an interval of 10 minutes for half an hour after the direct infusion of hydrocortisone or saline, and for one hour after intravenous administration of acetazolamide or aminophylline. The results of the experiment were as follows: 1. Significant changes in urine volume and urinary electrolytes (excreted rates of $Na^+,\;K^+\;and\;Cl^-$) were observed in the hydrocortisone-infused group 10 minutes after the administration of acetazolamide, compared with the saline-infused group. Especially, the effect was more potent on the infused (left) side than on the contralateral (right) side. 2. Significant changes in urine volume and urinary electrolytes were also observed in all the aminophylline-treated groups, but no remarkable difference was noticed between the hydrocortisone-infused group and the saline-infused group, nor between the left and right sides. 3. No signicant changes in the clearances of inulin and PAH were in the infused (left) side of all the experimental groups, as compared with the contralateral (right) side. From the above results, it is obvious that hydrocortisone infused into a renal artery exerts diuretic action when administered in combination with acetazolamide, and the mechanism of action rests not on its hemodynamic change for renal blood flow, but on the potentiation of carbonic anhydrase inhibiting action. However, the exact mode of action remains yet to be clarified.

A 33-years-old female pateint with cerebral palsy showing spastic quardriplegia and severe mental retardation was scheduled for dental implant restorations. Before implant surgery we had to take implant CT. But, because of her involuntary motion and communication difficulty, sedation was needed in order to take CT. After 8 hour NPO, propofol infusion sedation with TCI (target controlled infusion) system was administered. The propofol blood concentration of the patient was maintained 2-3 ${\mu}$/ml to keep deep sedation to prevent uncontolled movement. During sedation, we monitored ECG, pulse oximetry, blood pressure, capnometry for patient safety. Oxygen was administered via nasal prong for preventing hypoxemia and to keep airway during sedation some bands were applied to lift mandible. Total duration was 20 minutes for taking CT, and she was discharged from hospital after 30 minute rest without complication.

Objective : High-molecular-weight hydroxyethyl starch (HES) compromises blood coagulation more than does low-molecular-weight HES. We compared the effects of low- and high-molecular-weight HES for the treatment of vasospasm and investigated the dose relationship with each other. Methods : Retrospectively, in a series of consecutive 102 patients with subarachnoid hemorrhage (SAH), 35 patients developed clinical symptoms of vasospasm of these fourteen patients were treated with low-molecular weight HES for volume expansion while the other 21 received high-molecular-weight HES as continuous intravenous infusion. Prothrombin time (PT), partial thromboplastin time (PIT), fibrinogen level, and platelet count were all measured prior to initiation, during treatment and after termination of therapy for symptomatic vasospasm. The total dose of HES ranged from 5 L to 14 L and median infusion duration was 10 days. Results : A more pronounced PTT prolongation was observed in high-molecular-weight HES group compared with low-molecular-weight HES group. No other coagulation parameters were altered. Dosage (=duration) shows a positive correlation with PTT. Clinically, significant bleeding episodes were noted in four patients who received high-molecular-weight HES. Conclusion : Coagulopathy was developed in direct proportion to molecular weight of starch and dosages. We propose the extreme caution in the administration of HES solution for the vasospasm treatment.

Although the antidepressant effects of imipramine (IMI) have been well known in several studies, the effects on cardiovascular system, particularly the vasorelaxant effects, have not known clearly. We hypothesis that IMI-induced vasorelaxation involves NO (nitrie oxide), activation of guanylate cyclase (GC) and $Ca^{2+}$ channel. The possible roles of the endothelium and $Ca^{2+}$ in IMI-induced responses were investigated using isolated rings of rat thoracic aorta and anesthesized rats. In KCl-precontracted rings. IMI produces endothelium-dependent and endothelium-independent relaxations in intact (+E) as well as endothelium-denuded (-E) rat aorta in a concentration-dependent manner. In phenylephrine (PE)-precontracted rings, the IMI-induced relaxation was significantly greater in +E rings. The IMI-induced relaxations were suppressed by nitric oxide synthase (NOS) inhibitors, N(G)-nitro-L-arginine (L-NNA), N(omega)-nitro-L-arginine methyl ester (L-NAME) and aminoguanidine, a non-selective GC inhibitor, methylene blue, $Na^+$ channel blockers, lidocaine and procaine, or $Ca^{2+}$ channel blockers, nifedipine and verapamil, in PE-precontracted +E rings, but not in PE-precontracted -E rings. These relaxations were also suppressed by lidocaine or procaine in -E aortic rings. However, IMI-induced relaxations were not inhibited by a PLC inhibitor 2-nitro-4-carboxyphenyl-n,n-diphenylcarbamate (NCDC), an inositol monophosphatase inhibitor, lithium, indomethacin and dexamethasone in +E and -E rings. In vivo, infusion of IMI elicited significant decrease in arterial blood pressure. After intravenous injection of saponin, NOS inhibitors. MB and nifedipine, infusion of IMI inhibited the IMI-lowered blood pressure markedly. These findings suggest that the endothelium-dependent relaxation induced by IMI is mediated by activation of NO/cGMP signaling cascade or inhibition of $Ca^{2+}$ entry through voltage-gated channel, and this mechanism may contribute to the hypotensive effects of IMI in rats.

A total of 40 patients having a diagnosis of atherosclerotic coronary arterial disease were analysed on the operative outcomes according to variables as follows: 1) preoperative risk factors such as age, sex, CCS (Canadian Cardiovascular Society) functional class, type of angina, number of diseased vessel, presence of left main coronary artery stenosis, previous history of habitual smoking and presence of other medical diseases (diabetes mellitus, essential hypertension), 2) preoperative management such as intravenous infusion of nitroglycerine, preoperative IABP (intra-aortic balloon pump) support and whether the operation was scheduled as emergency or not, 3) intraoperative variables such as infusion method and composition of cardioplegic solutions, number of distal anastomosis, use of internal mammary artery, total cardiopulmonary bypass time and total cross clamp time. Complications included operative death in 12.5％, perioperative myocardial infarction in 25.0％ and perioperative arrhythmia in 17.5％. Nineteen perioperative variables were analyzed to identify risk factors for these end points. For operative death, presence of left main coronary artery stenosis (p = 0.056) and cardiopulmonary bypass time (p = 0.029) were significant in the univariate analysis, but presence of left main coronary artery lesion (p = 0.011, $\chi$$^2$= 6.45) and abscence of preoperative of IABP support (p = 0.069, $\chi$$^2$ = 3.30) were independent predictor in multivariate analysis (stepwise linear logistic regression).
