  • Objectives : The purpose of this study is to review clinical studies about the efficacy of fire needling for the treatment of acne vulgaris. Methods and Results : In this review, Oasis, NDSL, CNKI, PubMed, Cochrane, J STAGE and CINII were used as the main databases for searching for medical journals, using the keywords "acne and fire needling"," acne and fire needle"," acne and fire acupuncture", and" acne and red hot needle". The initial search range included only randomized controlled trials (RCTs), and papers not matching inclusion criteria were excluded. Initially a total of 108 studies were found, with ten being excluded during title and abstract screening. After scanning 98 papers, a total of 31 RCTs were selected and analyzed. In the 31 RCTs, patients with acne were randomized into groups for treatment and control. Specifically, the treatment group received fire needling, while the control group were concurrently given other treatments. The results of the completed studies have shown that the treatment group receiving fire needling demonstrated significant improvement compared to the control group. Conclusion : During our study, it was verified that the efficacy of fire needling for the treatment of acne vulgaris was both significant and meaningful. Therefore, fire needling can be a safe and effective alternative treatment for acne. However, to confirm this result, further investigation in a traditional clinic is required, accompanied by high quality studies including randomized, placebo-controlled double-blind trials.

  • Background: Recent studies suggested that a preoperative block of N-methyl-D-aspartate (NMDA) receptors with NMDA antagonists may reduce postoperative pain. In this double-blind study, magnesium sulfate, a natural NMDA receptor antagonist, was administered preoperatively to investigate the effects of magnesium sulfate on postoperative pain and pulmonary function. Methods: Seventy patients who were to undergo gastrectomy under general anesthesia were randomly assigned to one of three groups. Groups 2 and 3 received intravenous magnesium, preoperatively (Group 2: 50 mg/kg bolus, 7.5 mg/kg/hr for 20 hr, Group 3: 50 mg/kg bolus, 15 mg/kg/hr for 20 hr). Group 1 received normal saline as the control group. Visual analog scale (VAS) for postoperative pain and mood, cumulative analgesic consumption, recovery of pulmonary function and side effects were evaluated at 6, 24, 48 and 72 hours after the operation. Results: In Groups 2 and 3, plasma concentration of magnesium were significantly higher than in Group 1 at 6 and 20 hours after infusion (P<0.05). There were no significant differences in the analgesic consumption, and recovery of pulmonary function and the incidence of side effects at 6, 24, 48 and 72 hours after the operation among the three groups. In Group 3, pain scores at rest measured 24 and 48 hours after operation were lower than the control group, and pain scores when deep breathing were significantly lower than the control group at postoperative 6, 24, 48, and 72 hours. Conclusions: We conclude that intravenous infusion of greater amount of magnesium has little effectiveness in reducing postoperative pain. However, further studies are needed to characterize the clinical significance of these effects on postoperative pain.

  • Background: Although early reviews of clinical findings were mostly negative, there is still a widespread belief for the efficacy of preemptive analgesia among clinicians. In this study, we evaluated whether the preemptive use of ketamine decreases post operative pain in patients undergoing appendectomy. Methods: In double-blind, randomized clinical trials, 80 adult male patients undergoing an operation for acute appendicitis were studied. Patients were randomly assigned to two groups. In the operating room, patients in the ketamine group received 0.5 mg/kg of ketamine IV 10 minutes before the surgical incision. In the control group, 0.5 mg/kg of normal saline was injected. The pain intensity was assessed at time 0 (immediately after arousal) and 4, 12, and 24 hours postoperatively using the 10 points visual analogue scale (VAS). Results: Eighty patients (40 for both groups) were enrolled in this study. For all of the evaluated times, the VAS score was significantly lower in the ketamine group compared to the control. The interval time for the first analgesic request was $23.1{\pm}6.7$ minutes for the case group and $18.1{\pm}7.3$ minutes for the control (P = 0.02). The total number of pethidine injections in the first 24 hours postoperatively was $0.6{\pm}0.6$ for the case group and $2.0{\pm}0.8$ for the controls (P = 0.032). There were no drug side effects for the case group. Conclusions: A low dose of intravenously administered ketamine had a preemptive effect in reducing pain after appendectomy.

  • The aim of this study was to investigate the effects of chicory fructan fiber supplementation on bone mineral density, apparent absorption of minerals and serum parameters related to bone turnover in postmenopausal women. Twenty-six healthy Korean postmenopausal women participated in the study. 1be participants were randomly divided into two groups in a double-blind parallel design and took one of the supplements for 3 months; either a placebo of 8g maltodextrins/sucrose mixture (control group) or 8g chicory fructan fiber (fructan group). During the 3-month experimental period no differences were found in bone mineral density (BMD) between the two groups. Apparent calcium absorption significantly increased by 42% in the fructan group, while that of the control group decreased by 29% as compared to the values at baseline. Urinary calcium excretion was not significantly different between the group;;. After 3 months, the level of serum alkaline phosphatase (ALP) was significantly lower in the fructan group than in the control group and deoxypyridinolin showed a trend toward a slight reduction. In conclusion, intake of chicory fructan fiber with a regular increases apparent calcium absorption in postmenopausal women.

  • Purpose: The purpose of this study was to compare desflurane anesthesia with desflurane-remifentanil anesthesia by measuring postoperative pain, nausea and vomiting after gynecologic laparoscopic surgery. Methods: Data were collected using a random double blind method. The experimental group treated with desflurane-remifentanil anesthesia had a total of 25 patients. The control group had 20 patients who were treated with desflurane anesthesia. Pain (VAS), pushing PCA button, nausea and vomiting (VAS) were assessed at PACU (Post Anesthesia Care Unit) arrival, 10 min, 20 min, 30 min in PACU and 2 hrs, 6 hrs, 24 hrs, 48 hrs in ward. INVR was assessed at 24 hrs. Extra analgesics and extra antiemetics were measured in PACU and the ward. Data were analyzed using t-test and repeated measure using ANOVA. Results: The experimental group presented with more postoperative pain (F=7.55, p<.001) than the control group. The experimental group took more extra analgesics in PACU and pressed the PCA button more often for 6 hours. The experimental group complained more postoperative nausea (F=2.11, p=.043) than the control group and took extra antiemetics during postoperative period of 24 hours. Conclusion: We conclude that desflurane-remifentanil anesthesia needs better management than desflurane anesthesia due to increased pain, nausea & vomiting after gynecologic laparoscopic surgery.

Methods : The antibacterial activity was evaluated using triple distilled water and the Kirby-Bauer disk diffusion method and the minimal inhibitory concentration(MIC) against various pathogens for periodontal disease, such as P. gingivalis 381(ATCC33277), was estimated. The experimental groups classified according to the concentration of garlic extract used: 10,000ppm(A), 5,000ppm(B), 2,500ppm(C), 1,000ppm(D). Oral examination of subjects was performed through clinical periods and on day of baseline, 6, 12, 19, 25 days plaque index and gingival index were scored by Turesky' modified index and Loe & Silness index. After 12, 19, 25 days use of their respective dentifrices, statistically decreases of plaque index, gingival index were shown in both the experimental and the control group, respectively. Results : There was significant antibacterial activity in the "2,500ppm(C)" group against P. gingivalis 381. Experimental group exhibited significantly the lower plaque levels and the higher levels of gingival health by the use of the dentifrices contained extract of garlic from 6 days compare with control group(p<0.05). The degree of decrease was more significant on gingivitis level of the experimental group than the control group(p<0.05). Conclusions : This findings indicated that the oral products containing a garlic extract is effective in preventing and treating periodontal diseases, and has potential value in inhibiting periopathogens.

  • These studies were performed to establish more effective surgical method for correcting congenital atresia coli in calves. Distal colon fistulation, proximal colon fistulation and colon anastomosis which could be applied for surgical repair of intestinal obstruction were carried out in goatlings experimentally and in calves with atresia coli clinically. After treatment of the animals clinical signs, blood component values, body weight gain, survival and necropsy findings were observed. In goatlings, clinical signs after colon fistulation were diarrhea, anorexia and vitality loss, and those of proximal colon fistulation group were severer than those of distal colon fistulation group. Surviviability after operation was 9~16 weeks in distal colon fistulation group, 2~8 weeks in proximal colon fistulation group, and 2-3 days in colocolic anastomosis group, respectively. There were no alterations in blood component values among experimental groups. Weight gain rates were 54.6% in distal colon fistulation group and 42.9% in proximal colon fistulation group compared with those of control. Necropsy findings observed in experimental groups were distension of intestine and excessive fluid in abomasum and intestine. Two calves with atresia coli died 1 day and 6 days after operation but one with colon fistulation survived more than two months. Preoperative clinical signs in calves with atresia coli were abdominal distension, progressive anorexia, no defecation and postoperative clinical signs wert diarrhea and periodic abdominal distension. After operation there were no alterations in blood component values between the calf with atresia coli and control calf. Weight gain rate of calf with atresia coli was similar to that of control but revealed the tendency to decrease from the 2nd month after operation. Necropsy findings observed in two calves with atresia coli were intestinal distension. intraluminal excessive fluid, blind atretic sac and absence of intrarectal content. It was concluded that proximal or distal colon fistulation could be available for surgical correction of congenital atresla coli and prognosis of distal colon fistulation was better than of proximal colon fistulation, but that extensive colocolic anastomosis could not be compatible with life in ruminants.
