The present experiment was performed in 35 normal male volunteers to evaluate the effect of electroacupuncture on the human nociception more clearly and to demonstrate the effect of different parameters of electrical stimulation through acupuncture needles. The threshold of the pain(Tp) and the nociceptive flexion reflex(Tr), the threshold for intolerable pain(Tip) and that for obtaining maximal reflex response(Tmr) were studied before and after electroacupuncture performed on the acupoints of tsusanli and hsuanchung. 1) For the pricking pain, electroacupuncture with intermittent stimulation induced a significant decrease in Tp which recovered after removal of the needles. There was no significant change in other thresholds. 2) For the dull pain, electroacupuncture with intermittent stimulation produced a significant increase in Tp which continued after removal of the needles. But there was no signifcant change in Tip. Electroacupuncture with continuous stimulation induced a slight increase in Tp. 3) After resting without electroacupuncture, Tp and Tip of the dull pain were slightly decreased. These results suggest that electroacupuncture had no significant analgesic effect on the pricking pain induced by electrical stimulation of the foot skin. However, electroacupuncture with intermittent stimulation had significant analgesic effect on the weak dull pain and it had slightly greater analgesic effect than electroacupuncture with continuous stimulation.

Prostaglandins biosynthesis and nitric oxide production have been implicated in the process of inflammation. In this study we investigated on the effects of ethyl acetate extract of Angelica Koreana Radix (EAKR) on the activities of prostaglandin $E_2\;(PGE_2)$, proteoglycan (PG) degradation and nitric oxide synthase (NO) in inflammation cytokines-activated rabbit articular chondrocytes. EAKR exhibited inhibitory activities on NO production and $PGE_2$ production as $73.08\%\;and\;89.49\%$, respectively at $20{\mu}g/ml$ and inhibited the degradation of PG in a concentration-dependent manner Zelatin zymography analysis demonstrated that EAKR significantly inhibited MMP-2, 9 expression in chondrocytes. In vivo, EAKR was shown to have inhibitory effects on acetic acid-induced pain. This study suggests that modulation of $PGE_2$, NO, PG degradation and MMP-2, 9 by EARK may be important in the prevention of inflammation and osteroarthritis.

Purpose: The purpose of this study was to identify the effect of relaxation therapy on state anxiety, preterm labor stress, blood pressure, skin temperature, pulse rate of pregnant women with preterm labor and heart rate of their babies. Methods: The participants were 55 pregnant women with preterm labor who hospitalized from May, 2009 to January, 2010. 29 participants were assigned to experimental group and the other 26 participants to control group. All of them were not have any other complications except preterm labor. The relaxation therapy was applied to the experimental group for 5 days. Data were analyzed by the SPSS/WIN 14.0 program. Results: The state anxiety score and the preterm labor stress score of experimental group were statistically significant lower than those of control group. In addition, the systolic and diastolic blood pressure, pulse rate of experimental group were statistically lower than those of control group. The skin temperature of experimental group was higher than that of control group. However, the fetal heart rate of experimental group was not statistically significant lower than fetal heart rate of control group. Conclusion: From these findings, it is concluded that relaxation therapy may be an effective nursing intervention for pregnant women with preterm labor.

In order to obtain a good result in Arthroscopic ACL Reconstruction by immediate postoperative physical therapy, sufficient analgesia was needed. This study analyzes the analgesic effect of the intra-articular injection with ketorolac, Morphine together with bupivacaine in 80 male patients who had Arthroscopic ACL Reconstruction. On completion of the surgery under spinal anesthesia, the knee was injected with 30ml of 0.25% bupivacaine. Each of the study group received ketorolac and/or morphine, either through parenteral or intra-articular. Total amount of the drug used by Patient Controlled Analgesia(PCA) and Visual Analgesia Scale(VAS) for pain were measured and analyzed. The group which received intra-articular ketorolac or Morphine had a better analgesic effect than other group which received none. The group which received both did not do better in analgesic effect. Intra-articular infusion with either ketorolac or Morphine improved postoperative analgesia in Arthroscopic ACL Reconstruction surgery. However, combined injection did not offer more advantage.

Purpose: The purpose of this study was to examine the effects of providing information on Stress and maternal role confidence of pregnant women with preterm labor. Methods: The sample were 66 pregnant women with preterm labor admitted at 1 hospital in Busan. In the subjects, 33 were the experimental group and 33 were the control. Data was collected from March 1st to October 31st, 2007. A hand-out including the knowledge of preterm labor, fetus state and curing process. The tool for the stress had 14 questionnaires including the levels of anxiety and depress. And the tool for the maternal role confidence had 23 questionnaires. The data analyzed by $X^2$-test, t-test and pearson correlation coefficient with SPSS 12.0/pc program. Results: After providing information, the stress of the experimental group decreased significantly than the control(t=1.95, p=.048). And the maternal role confidence of the experimental group increased significantly than the control(t=-2.40, p=.016). There is a significant correlation between the stress and maternal role confidence(p<.01). Conclusion: The special program or educational nursing intervention should be created for each pregnant women with preterm labor and ante-natal nursing service may assessed and consulted on anxiety-depression and maternal role confidence.

Backgound: The present study was undertaken to determine whether fentanyl or bupivacaine is a better adjuvant to epidural morphine with respect to postoperative analgesic use and with fewer incidence of side effects. Methods: We evaluated the clinical effects in 62 patients having cesarean section, divided in 3groups randomly. Group I(n=19) was received epidural morphine 4 mg, group II(n=22) was received epidural morphine 2 mg plus fentanyl 50 ${\mu}g$ and group III(n=21) was received morphine 2 mg plus 0.25% bupivacaine 10 ml epidurally. We measured the first request time of analgesic for postoperative pain, the number of supplemental analgesics within 24 hours and the incidence of side effects postoperatively. Results: The first request time of analgesic for postoperative pain was significantly shorter in group III than in group I and II. The analgesic use in the first 24 hours was significantly more in group III than in group I and II. The side effects were significantly fewer incidence in group II than in group I and III. Conclusions: In conclusion, the combined use of epidural morphine and fentanyl provided better analgesia than the combined of epidural morphine and bupivacaine.

Caudal narcotic analgesia was assesses after the injection of 3mg morphine diluted in 30ml (physiologic) saline into the sacral canal in 15 Patients after upper abdominal surgery, in 20 patients after lower abdominal surgery under general anesthesia, and in 20 patients after perianal surgery under caudal block. Pain relief was evaluated by the subsequent need for systemic analgesics. All eases had considerable relief from pain an4 the morphine was effective for 12 or more hours. There were no significant differances between pain relief of the upper abdominal and lower abdominal surgery group, upper abdominal and perianal surgery group, and lower abdominal and perianal surgery group (p>0.05, p>0.05, p>0.05). It is suggested that the morphine, which was administered into the sacral, cannal, reached the subarachnoid space and produced it's effect by direct action on the specific opiate receptors in the substantia gelatinosa of th.8 posterior horn cell of the spinal cord. Consequently, whether analgesia from epidural narcotics appears to be segmental in distribution or not is still in controversy.

In recent years the use of epidural opiates has increased and although this method of pain relief has shown good results in clinical practice It is still subject to certain drawbacks, the most serious of which appears to be delayed respiratory depression. Since ketamine administered systemically is unlikely to produce respiratory depression it seemed worthwhile to investigate the possibility of exploiting the potent analgesic property to ketamine by its epidural administration. The analgesic effect of ketamine 4 mg, administered epidural space, was evaluated. The duration of pain relief varied from less than 3 hours in 20% to over 24 hours in 30% of the cases. In 62.5% of the cases pain relief exceeded 6 hours. There was no evidence of respiratory depression, and there no postoperative neurologic sequelae. The present results indicated the need for further studies to compare the efficacy and safety of epidural ketamine with the response to epidural opioids for the relief of postoperative pain.

The analgesic effects of epidural morphine were evaluated on various types of cancer-related pain in forty-eight adult patients. Epidural morphine injections were given via an epidural catheter introduced to an epidural level corresponding to the pain area. Pain relief was classified as excellent, fair, or poor by subjective scoring and by the subsequent need for systemic analgesics. Thirty-two patients of all the patients became pain-free. In sixteen patients, pain relief was complete only for one or two of various types of pain with a certain dose of epidural morphine, The best result was obtained when the pain was continuous and originated from deep somatic structures. Based on the results, the ranking order of different types of cancer pain with regard to their susceptibility to epidural morphine was as follows: 1) Continuous somatic pain 2) Continuous visceral pain 3) Intermittent somatic pain 4) Intermittent visceral pain The differential effects of epidural morphine on cancer-related pain may suggest that various types of noxious stimuli involve different kinds of opioid receptors which differ in affinity to morphine, and that there are some pain-mediating systems which function independently of opioid mechanisms.

Effrctive analgesia after elective thoracotomy can be provided by continuous extrapleural intercostal nerve block.This study was designed to prove the effectiveness of continuous extrapleural intercostal nerve block. Twenty patients undergoing elective thoracotomy were randomized into two groups. Group I received lumbar epidural block[N=10] and group II received continuous extrapleural intercostal nerve block[N=10]. Postoperative pain relief was assessed on Numeric Rating Scale[NRS] and recovery of pulmonary function was assessed by coparison of preoperatrive and postoperative FVC[Forced Vital Capacity], FEV1[Forced expiratory Volume in 1 second], VC[Vital Capacity]. Arterial blood gas analysis[ABGA], vital signs and amount of additive analgesics were compared also. No significant difference was observed between the groups concerning these parameters mentioned above. Systemic complications, such as urinary retention[2/10] and weakness of lower extremity[2/10], occurred in group I but no complication occurred in group II. We conclude that continuous extrapleural intercostal nerve block is as effective as epidural block in pain relief and restoration of pulmonary mechanics with fewer comlications. Also because of it`s ease and safetiness, this must be considered as a substitute of epidural block in routine use for thoracotomy pain relief.
