  • A randomized, double blind, placebo-controlled human intervention study involving 58 menopause women was performed to investigate the effect of pomegranate extracts on menopausal symptoms. The volunteers were randomly distributed into two groups, one taking pomegranate extracts (1.5 g/day) and the other being a placebo by taking oral administration for 8 weeks. The results from this study showed that duration of hot flush and sweating were significantly decreased by taking pomegranate extracts. In addition, menopausal rating scales and the Kuppermann index were significantly decreased in pomegranate extract taking group. This result suggests a possibility that pomegranate extracts can be helpful for menopause women.

  • Background: The purpose of this study was to determine whether there is any advantage for a continuous background infusion during patient controlled epidural analgesia(PCEA) for postoperative pain control. Methods: 60 patients scheduled for elective cesarean section under epidural anesthesia were assigned randomly in a double-blind fashion to receive fentanyl and bupivacaine by PCEA with or without background infusion for 48 hours postoperatively. Results: Total amount of fentanyl and bupivacaine consumption and degree of sedation were not significantly different between the two groups. Visual analogue scale(VAS) pain scores at 24, 36, and 48h and sleep disturbance were significantly lower in background infusion group. Conclusion: Administration of fentanyl with bupivacaine by continuous background infusion is appropriate for PCEA for postcesarean section pain control.

  • Many studies show that the bone loss in postmenopausal women is closely related with status of vitamin K. The purpose of this study is to observe the effects of the vitamin K supplements on the carboxylation of serum osteocalcin in postmenopausal women. Twenty-four healthy postmenopausal women were recruited for the double-blind controlled study. Before and after daily administration of 1.0mg of phylloquinone for one month, the levels of serum vitamin K, osteocalcin, undercarboxylated osteocalcin were measured. Daily intake of vitamin K was also calculated. After the 4-weeks of supplements of 1.0mg/day of vitamin K, there were no significant differences for the levels of serum vitamin K, osteocalcin, and ucOC between the experimental and placebo groups. In this study, it was not found that the supplements of vitamin K to the postmenopausal women had any positive effects on.

  • Epidural injection of narcotics for postoperative pain relief has been well reported. Caudal nalbuphine was assessed as a postoperative analgesic in a randomized double blind study of 80 patients after perianal surgery. Caudal block was carried out with 1.5% lidocaine 25 ml (Group 1) in 20 patients, and mixed with nalbuphine 3 mg (Group 2) in 20 patients, nalbuphine 5 mg (Group 3) in 20 patients, and nalbuphine 10 mg (Group 4) in 20 patients. Pain relief was evaluated by the subsquent need for systemic analgesics (Pethidine). In group 4, the use of systemic analgesics was significantly reduced for the first 24 hours postoperatively. Urinary retention was not correlated with nalbuphin dose.

  • 족관절 내 히알루론산 주사 후 효과에 대한 참고 자료를 살펴 본 결과 대부분의 연구들이 족관절 내 히알루론산 주사에 대한 효과와 안전에 대해 긍정적으로 보고하고 있지만, 아직까지는 결론을 짓기는 어렵다고 하겠다. 추후 많은 환자를 대상으로 한 무작위 이중맹검 위약대조군 연구(randomized double-blind placebo-controlled trials)를 통해 그 결과를 평가해야 할 것으로 사료되며, 또한 장기 추시를 통해 효과 발현 시기 및 지속 기간을 평가해야 할 것이다.

  • Purpose: This study was done to identify effects of carbonated water intake on constipation in elders who have experienced a cerebrovascular accident (CVA) and are bed-ridden. Methods: Forty elderly patients with CVA were randomly assigned to one of two groups in a double-blind study. Patients in the experimental group drank carbonated water and those in the control group drank tap water for two weeks. Six patients dropped out during the study period. Data were analyzed by repeated measured ANCOVA and the covariance was the dose of laxatives used for the two weeks. Results: Frequency of defecation increased significantly and symptoms of constipation decreased significantly for patients in the experimental group. Conclusion: The study results suggest that the intake of carbonated water is an effective method for the intervention of constipation in elderly patients with CVA.

  • Rotator cuff tear is a common reason for shoulder pain. Although the surgical technique of rotator cuff repair is developing, high retear rate requires additional supplementary methods. Among these supplementary methods, as a kind of biologic augmentation, platelet-rich plasma (PRP) has been spotlighted and has recently been studied by many researchers. PRP, a concentrate of platelet extract obtained from whole blood, contains numerous growth factors. As this is known to play an important role in the tissue recovery process, it had been used for research in a variety of fields including orthopedics. Use of PRP has been attempted in surgical treatments of rotator cuff tear for better results; however, only a few large-scale research studies on the effect of PRP have been reported. Clinical results of each study are also variable. Therefore research using large-scale randomized, double-blind trials should be conducted in order to prove the application range, safety, and clinical effects of PRP.

  • Caudal buprenorphine was investigated as a postoperative analgesic in a randominzed double blind study of 45 patients after abdominal surgery. At the end of surgery, patients were given 0.2 mg of caudal buprenorphine in 20 ml saline(n=30, experimental group) or no injection(n=15, control group). Pain relief was evaluated by the subsequent need for systemic analgesics(pethidine). Arterial blood gas and micturition disturbance were evaluated. In the buprenophine group, use of systemic analgesics was significantly reduced for the first 24 hours postoperatively. Arterial blond gas study values 2 hollers after buprenorphine administration were within normal range. 8 patients of the buprenorphine group developed urinary retention requiring temporary Nelaton catheterization of the bladder. Caudal buprenorphine for postoperative pain control was a good alternate method of postoperative pain management.
