Purpose: In the present study, the actual management state of trial contact lenses and lens care products in local optical shops was surveyed and analyzed to reduce the risk of lens complication possibly induced by neglecting lens care. Methods: The feeling of contact lens wearers during the wear of trial contact lenses was surveyed. Futhermore, the actual management state of trial contact lenses such as cosmetic lens and RGP lens and lens care products was also investigated by surveying opticians who trade contact lenses in local optical shops. Results: It was found that consumers trusted the sanitary conditions of the lens since trial cosmetic contact lens and RGP lens were cleaned before and after trails by over 98% of opticians in local optical shops. For trial cosmetic lens, cleaning with normal saline, multipurpose solution for soft lens and combination of saline and multipurpose solution were 38.5%, 40.5% and 21%, respectively, before trials. After trials, cosmetic lenses were cleaned with normal saline, multipurpose solution for soft lens and a combination of saline and multipurpose solution were 13%, 75%, and 12%, respectively. On the other hand, cleaning with normal saline, multipurpose solution for RGP lens and combination of saline and multipurpose solution were 28.5%, 38.5% and 33%, respectively, before trying trial RGP lens. After trials, RGP lenses were cleaned with normal saline, multipurpose solution for RGP lens and a combination of saline and multipurpose solution were 2.5%, 70%, and 27.5%, respectively, indicating that relatively many opticians followed the lens cleaning regimen. In local optical shops, the cleaning trial cosmetic lens was mainly conducted at every 10 days or a month and the washing cycle of cosmetic lens case was in a month or 2~3 months. The cleaning interval of trial RGP lens was primarily in a month or 2~3 months. For those lens cases, more than 75% of opticians washed them with a surfactant and then rinsed with cold water. The storing periods of lens care products were primarily in a week for saline and in a month and 2~3 months indicating that storing period of lens care products was relatively well-kept in local optical shops. Conclusions: It is thought that the concern about any microbial infection is not that high since trial contact lenses and lens care products were generally well-managed by opticians in local optical shops from the results above. However, better public eye health and better public confidence in opticians may be possible if further strengthen in avoidance of lens cleaning with saline, keep of cleaning cycles within 2 weeks and rinsing of lens cases with hot water happens.

Purpose: The purpose of this study was to analyze the effectiveness of saline solution vs. heparinized-saline for maintenance of arterial lines and to detect changes in platelet and aPTT as physiological indexes. Methods: In this nonequivalent control group, non-synchronized, double-blind study the effects of heparinized and saline solution on the maintenance of arterial lines were compared. Fifty five patients received the heparinized solution and fifty nine patients received the saline solution. All patients who had surgery in K-university hospital between September and December 2011 were eligible for participation in the study. Results: There was no statistically significant difference between the saline and the heparin group in the maintenance time of the arterial lines or the number of irrigations. There was no statistically significant difference between the groups in changes in the number of platelets and aPTT for interaction between the groups and time intervals. Conclusion: The results indicate that saline solution can be used as an irrigation solution for the maintenance of arterial lines of adult surgical patients, rather than heparinized-saline, in view of potential risk factors in the use of heparin.

Objectives : This study was to investigate the effects of Clematidis Radix on Proteoglycan(PG) degradation by measuring of body weight, Glycosaminoglycan(GAG), Interleukin-$1{\beta}$($IL-1{\beta}$) in synovial fluid, and PG content of articular cartilage of femur in collagenase-induced arthritis in rats. Methods : Arthritis was induced by injection of collagenase(0.1 ml) into knee joint of rats. Arthritic rats were divided into control(n=8) and treated(n=8) group. Control group was taken normal saline for 15 days and treated group was taken extracts of Clematidis Radix for same duration. Normal group(n=8) was injected with normal saline and was taken normal saline for 15 days. Body weight was measured at 0, 10, 15 days after injection. GAG, $IL-1{\beta}$ in synovial fluid were measured with ELISA kit at 15 days after injection. PG content of articular cartilage of femur, represented by safranine O staining, was measured at 15 days after injection. Histopathological study on the articular cartilage of knee joint was investigated at 15 days after injection. Results : Body weight, PG of treated group, taken Clematidis Radix, were significantly increased, and GAG was significantly decreased compared with control group. But $IL-1{\beta}$ was not significantly decreased. Conclusions : On the basis of these results, we concluded that Clematidis Radix has inhibiting effects on the proteoglycan degradation in collagenase-induced rat osteoarthritis model.

Purpose: The aim of this study was to evaluate the clinical characteristics and outcome of patients who presented to the emergency department (ED) with cardiotoxicity caused by ingestion of Himalayan mad honey. Methods: Medical records of 12 patients who presented to the ED from January 1, 2005 to December 31, 2012 with cardiotoxicity caused by ingestion of Himalayan mad honey were retrospectively reviewed. Results: The mean age of patients was 54.5 years and 58.3% were men. The median amount of mad honey ingested was 30.0 cc, and the mean time from ingestion to onset of symptoms was 39.4 minutes. All patients had hypotension and bradycardia upon arrival in the ED. The initial electrocardiogram showed sinus bradycardia in seven patients, junctional bradycardia in four patients, and atrial fibrillation with slow ventricular response in one patient. Four patients were treated with intravenous normal saline solution only. Eight patients were treated with intravenous normal saline solution and atropine sulfate in a dose ranging from 0.5 to 2.0 mg. Blood pressure and pulse rate returned to normal limits within 24 hours in all patients. Conclusion: Our study showed that all patients with cardiotoxicity caused by ingestion of Himalayan mad honey had severe hypotension, bradycardia, and bradyarrythmias, including sinus bradycardia and junctional bradycardia and all patients responded well to conservative treatment, including intravenous normal saline solution and intravenous atropine sulfate.

Objectives : The purpose of this study is to investigate the effects of Hyangsayangwi-tang (Xiangshayangwei-tang) intravenous herbal acupuncture (HYT-IVHA) on emesis and gastric hypomotility induced by chemotherapy in rats. Methods : The experimental animals were randomly allocated into six groups (normal, cisplatin, saline, HYT-1, HYT-2, HYT-3), and each group included five rats. The rats in the normal group did not receive any treatment. Those in the cisplatin group had no additional treatment after intraperitoneal injection of cisplatin (7 mg/kg). Those in the saline group were injected with saline $0.4m{\ell}$ via the tail vein after the injection of cisplatin. Those in the HYT-1 group, HYT-2 group, HYT-3 group were injected with $0.4m{\ell}$ of Hyangsayangwi-tang (Xiangshayangwei-tang) intravenous herbal acupuncture solution (HYT-IVHAS) via tail vein after the injection of cisplatin, and the concentrations were 0.199 g/kg, 0.066 g/kg, 0.022 g/kg respectively. Then we measured body weight, food intake and kaolin consumption before and at 12h, 24h and 36h after the injection of cisplatin. The remaining amount of food within the rat's stomach was also measured at 36h after cisplatin injection. Results : Kaolin consumption was significantly increased in the cisplatin group compared to the normal group, while significantly reduced in HYT-1, HYT-2, HYT-3 groups compared to the cisplatin group. The remaining amount of food in stomach was significantly increased in the cisplatin group and HYT-1 group compared to the normal group, but significantly reduced in the HYT-3 group compared to the cisplatin group. Conclusions : HYT-IVHA has an therapeutic effect on chemotherapy-induced emesis and gastric hypomotility.

The purpose of this study was to evaluate the disinfection efficacy of root canal irrigation method and irrigation solution in infected root canals. Access cavity were prepared in single-rooted extracted human teeth and each canals were prepared with step-back method and sterilized with ethylene oxide gas. Prepared teeth were experimentally inoculated in the canals for 30 minutes with four aerobes(Streptococcus mutans, Stapylococcus aures, Streptococcus sanguis, and E. coli) and two anaerobes(Streptoccus intermedius, and Clostrium perfringens). Normal saline, 3% $H_2O_2$, and 3% NaOCl were used as irrgation solutions. And root canals were irrigated with each irrigation solutions manually with disposible syringe or ultrasonic instument. (Apoza Uitrasonc, Taiwan). The irrigation effect on the eradication of S. aures and S. intermedius with normal saline was not similar between manual method and ultrasonic method. No significant differences were observed in the eradication of E. coli and C. perfringens among the irrigation solution and irrespective of the irrigation methods. In S. aurues and S. mutans, there was somewhat different eradication effect according to irrigation solutions, but there was no significant difference between manual method and ultrasonic methods. These results suggest that ultrasonic irrigation method with saline is more effective in some strains than manual irrigation.

The purpose of this study was to evaluate the cleansing effect of Glyoxide on the dentinal walls of the root canal. Fourty teeth were divided into four groups and the canals in each group were individually enlarged with K-file by step-back technic and irrigated with one of four irrigants. The four used irrigants were Glyoxide (Marion lab. U.S.A.) in combination with 3.5% sodium hypochlorite, 3.5% sodium hypochlorite, 3.5% sodium hypochlorite in combination with 3% hydrogen peroxide and normal saline solution. All the irrigants were used in conjunction with instrumentation as they would be during clinical conditions. After final irrigation, the canals were dried with paper points and the teeth were split longitudinally. The cleaness of canal walls according to the size and the level of canals were evaluated under steroscope by t analysed statistically The results were as follows. 1. The use of 3.5% sodium hyphochlorite in combination with 3.0% hydrogen peroxide revealed the most clean canal surface regardless of the size of canal at apical third of root canal (p < 0.05). 2. Glyoxide in combination with 3.5% sodium hyphchlorite showed no significant difference in cleaning effect of canal surface compared with 3.5% sodium hypochlorite and normal saline solution at the apical third of narrow canal. 3. Glyoxide in combination with 3.5% sodium hypochlorite revealed no significant difference in debridement of canal walls compared with 3.5% sodium hypochlorite in combination with 3% hydrogen peroxide and saline solution at the middle third of narrow and large canals.

Purpose: This study aimed to compare the effects of the Difflam spray 0.3% with the sodium bicarbonate-normal saline spray on oral care for postoperative patients. Methods: The participants were randomly allocated to either the Difflam (n=22) group or the saline solution (n=23) group. The data were collected at the 1-, 4-, 7-, and 10-hour marks after returning to the ward post operation using the Beck's subjective oral discomfort scale, Visual Analogue Scale for sore throat, and portable halitosis detector. Results: The sore throat (F=7.25, p=.001) score significantly decreased after oral care using the Difflam spray 0.3%. However, the difference in the scores of oral comfort (F=0.34, p=.797) and halitosis (F=0.91, p=.443) between the two groups was not statistically significant. Conclusion: These findings suggest that the Difflam spray 0.3% is effective in improving postoperative sore throat. A further study that explores the effect of various oral solutions for postoperative patients is needed to present systemic and effective evidence-based oral care guidelines.

Objectives: This study aimed to evaluate the potential toxicity of a recently developed and clinically used No-Pain pharmacopuncture (NPP) solution. We also assessed the lethal dose of the NPP agent following a single intramuscular injection in Sprague-Dawley (SD) rats. Methods: Animals were divided into two groups: the NPP test material group and the normal saline control group. A single intramuscular injection of the NPP agent (1.0 mL/animal) was administered to rats of the NPP test material group. The control group rats received the same volume of normal saline. Both female and male rats were included in each group. All rats were monitored for clinical signs and body weight changes for 14 days after administration of the test substance or saline. At the end of the observation period, a gross necropsy was conducted and localized tolerance at the injection site was analyzed. Results: No mortality was observed in the NPP test material and control groups. Moreover, no test substance-related effects were observed on clinical signs, body weight, necropsy findings, and localized tolerance at the injection site. Conclusion: The approximate lethal dose of the NPP agent is greater than 1.0 mL/animal under the conditions used in this study. Additional toxicity evaluations and clinical studies are needed to confirm the safety of NPP use in clinical practice.
