This study was aimed to evaluate the prophylactic anti-glaucoma effect of topical 5% betaxolol (BTX) and 2% dorzolamide (DRZ) on the second eye in dogs with unilateral primary angle closure glaucoma (PACG). Medical records of 60 dogs with unilateral PACG who received prophylactic anti-glaucoma eyedrops in the second eye, from 2016 to 2021, were reviewed. The prophylactic effects of BTX were maintained on 28/60 (46.7%) eyes until last visit and BTX failure was observed on median 510 (range, 53-1,927) days in 32/60 (53.3%) eyes. After DRZ instillation in BTX failure eyes, the prophylactic effects were extended at median 610 (range, 157-2,270) days in 21/32 (65.6%) eyes. DRZ failure eyes (17/21, 81.0%) eyes required chemical ablation or surgical intervention due to uncontrolled intraocular pressure. The duration of prophylactic effects was decreased with aging (R² = 0.334, p = 0.006). The predominant breeds were Shih-Tzu (41.9%) and American Cocker Spaniel (30.6%) with no significant differences in survival curves (p = 0.210). The average prophylactic effects of BTX persisted more than 1.5 year and could be selected the first prophylactic eye drop in unilateral PACG. Also, early surgical intervention should be considered in prophylactic medications failure cases.

Purpose: The aim of this study was to evaluate the effects of various prophylactic treatments of titanium implants on bacterial biofilm formation, correlating surface modifications with the biofilms produced by Pseudomonas aeruginosa PAO1, Staphylococcus aureus, and bacteria isolated from saliva. Methods: Pure titanium disks were treated with various prophylactic procedures, and atomic force microscopy (AFM) was used to determine the degree to which surface roughness was modified. To evaluate antibiofilm activity, we used P. aeruginosa PAO1, S. aureus, and saliva-isolated Streptococcus spp., Bacteroides fragilis, and Staphylococcus epidermidis. Results: AFM showed that the surface roughness increased after using the air-polishing device and ultrasonic scaler, while a significant reduction was observed after using a curette or polishing with Detartrine ZTM (DZ) abrasive paste. In addition, we only observed a significant (P<0.01) reduction in biofilm formation on the DZ-treated implant surfaces. Conclusion: In this study, both AFM and antibiofilm analyses indicated that using DZ abrasive paste could be considered as the prophylactic procedure of choice for managing peri-implant lesions and for therapy-resistant cases of periodontitis.

Purpose: The aim of this study was to investigate prophylactic treatment effects in Korean patients with severe hemophilia A. Methods: A prospective study of 32 severe hemophilia A patients was conducted with the approval of the Institutional Review Board at the Eulji University Hospital. Two patients received primary prophylaxis; whereas, the other 30 patients were divided into 2 groups-secondary prophylaxis (n=15) and on-demand (n=15)-on the basis of their consent for secondary prophylaxis. A 20-25 IU/kg dose of factor VIII concentrate was administered to the primary and secondary prophylaxis group patients every 3 days for 1 year. The prophylactic effect was evaluated by observing changes in the Pettersson scores, annual number of total and joint bleeds, and factor VIII consumption for 1 year. Results: No moderate or severe bleeding was observed, and the Pettersson scores remained unchanged during the prophylaxis period in the patients who received primary prophylactic treatment. After the treatment was changed from on-demand to secondary prophylaxis, the annual number of total and joint bleeds in the secondary prophylaxis group decreased by $64.4%{\pm}13.0%$ and $70.0%{\pm}15.2%$, respectively. The average increase in Pettersson scores within 1 year was $0.5{\pm}0.8$ and $1.3{\pm}1.1$ in the secondary prophylaxis and on-demand groups, respectively. Prophylactic effects were also observed in patients >17 years who had nearly the same initial Pettersson scores. Conclusion: Intermediate-dose prophylactic treatment may delay hemarthropathy progression and prevent its occurrence in Korean severe hemophilia A patients.

Purpose: This study was done to evaluate the combination effects of capsicum plaster at the Korean hand acupuncture points K-D2 with prophylactic antiemetic on Postoperative Nausea and Vomiting (PONV). Methods: An experimental research design (a randomized, a double-blinded, and a placebo-control procedure) was used. The participants were female patients undergoing gynecologic laparoscopy; the control group (n=34) received intravenous prophylactic ramosetron 0.3mg, while the experimental group (n=34) had Korean Hand Therapy additionally. In the experimental group, capsicum plaster was applied at K-D2 of both 2nd and 4th fingers by means of Korean Hand Therapy for a period of 30 minutes before the induction of anesthesia and removed 8 hours after the laparoscopy. Results: The occurrence of nausea, nausea intensity and need for rescue with antiemetic in the experimental group was significantly less than in the control group 2 hours after surgery. Conclusion: Results of the study show capsicum plaster at K-D2 is an effective method for reducing PONV in spite of the low occurrence of PONV because of the prophylactic antiemetic medication.

Objectives: Inflammatory bowel disease (IBD) is chronic inflammatory disorders of the intestines. Due to limitation of conventional treatment including steroids, herbal medicines have emerged as possible therapeutic options for IBD. The purpose of the current study was to investigate the therapeutic and prophylactic effects and mechanisms of Zostera Marina water extract (ZME) on DSS-induced colitis. Methods: Colitis was induced by DSS in Balb/c mice. In pre-treatment setting, ZME was administered 7 days before DSS treatment and in co-treatment setting, ZME was simultaneously administrated with DSS treatment. In both settings, ZME 100, 300 and 1000 mg/kg were orally administered twice a day, respectively. Mice weight and clinical findings were measured daily. Colon length, macroscopic findings and histological damages of colon mucosa were assessed at the end of experiments. The levels of cytokines including TNF-${\alpha}$, IFN-${\gamma}$, IL-$1{\beta}$, IL-6, IL-10 and IL-17 were measured by Biometric Multiplex Cytokine Profiling method. Results: In a dose dependent manner, ZME significantly inhibited the colon shortening, and improved macroscopic score and histological score. However, there were insignificant changes on inhibition of weight loss and improvement of clinical score. There were no significant differences of effects between co-treatment and pre-treatment settings. ZME 300 and 1000 mg/kg groups significantly inhibited IFN-${\gamma}$. Only ZME 1000 mg/kg group significantly inhibited TNF-${\alpha}$, IL-$1{\beta}$ and IL-6. Conclusions: The current results show the possibility of therapeutic use and its prophylactic application of ZME on inflammatory bowel diseases. Future studies for targeted mechanisms of ZME are needed.

Fucoidan is a sulfated polysaccharide derived from brown algae that has been reported to perform multiple biological activities, including immunostimulation. In this study, we investigated whether fucoidan has beneficial effects on endotoxemia induced by LPS, a septic model in mice. The focus of this study was on survival rates and spleen function of the mice upon treatment. We found that fucoidan had prophylactic effects on the survival rate of mice with endotoxemia. Flow cytometric analysis using antibodies for subset-specific markers revealed that fucoidan profoundly reversed the depleted population of dendritic cells in mice with endotoxemia. According to Western blot analysis, the spleen cells of LPS/fucoidan-treated mice showed a higher expression of anti-apoptotic molecules compared to those of LPS-treated mice. Also, fucoidan-treated spleen cells were more responsive to mitogens. Taken together, these results demonstrate that fucoidan pre-treatment has beneficial effects on the survival rate and function of the spleen in mice with endotoxemia. This study may broaden the use of fucoidan in clinical fields, especially endotoxemia.

This study was conducted to determine the effects of prophylactic supplementation of vitamin E and Se on oxidative damage and antioxidant status. Fifteen healthy male buffalo (Bubalus bubalis) calves between the age of 6 to12 months were divided into three groups of five animals each: Group I-control, group II-endotoxic shock group infused with lyophilized E coli endotoxin @ 5 ${\mu}g$/kg body wt, and group III-supplemented with vitamin E @ 250 mg and Se @ 7.5 mg, one month prior to induction of endotoxic shock. All the animals in group II and group III exhibited signs of endotoxic shock. When the endotoxic shock was induced, there was significant (p<0.05) increase in the circulating levels of malonyl dialdehyde MDA (an indicator of lipid peroxidation). In the supplemented group III the magnitude of formation of MDA was also less as compared to group II at every stage of study. There was significant (p<0.05) decrease in circulating levels of SOD, GSH-Px, Catalase and G-6-PD activity from the normal (0 h) value with passage of time. As a result of endotoxic shock, these values reached a lowest value, and then showed a tendency towards the 0 h value. Prophylactic supplementation with vitamin E and Se was successful in reducing the quantum of oxidative damage due to formation of free radicals because of endotoxic shock.

Background : The objective of this study was to examine the effect of management system for the appropriate prophylactic use of antibiotics in surgical patients at a tertiary hospital from 2007 to 2010. Methods : We collected clinical data of three different surgical procedures(colectomy, heart surgery, hysterectomy) for three months of 2007 and 2010, respectively. The number of total cases was 245(137, 54, 54) in 2007, 240(133, 42, 65) in 2010. We measured the rate of use of inappropriate prophylactic antibiotics, administration within 1 hour prior to the incision and the antibiotics prescription days after surgery. To evaluate the effectiveness of the management system, the results of the two groups(Group1=2007, Group2=2010) were compared by t-test, chi-square test or Fisher's exact test. Result : The rate of Aminoglycoside uses decreased drastically from 11.4% to 0.8%(P<.001). The selection of 3rd/4th Cephalosporin dropped from 11.8% to 5.8%(P=.020). The combination of antibiotics decreased from 27.8% to 11.7%(P<.001). The antibiotic prescription rate on discharge declined from 11.8% to 2.5%(P<.001) and the number of antibiotics prescription days after surgery was shortened from 4.2 days to 2.3 days(P<.001). No significant difference in the rate of administration within 1 hour between two groups was found. Through 3-year management, 5 out of 6 measures were significantly improved(except the administration within 1 hour). The rate of surgical site infection decreased from 2.4% to 1.3%(P=.504). Conclusion : The findings demonstrate that the management system for the prophylactic use of antibiotics in surgical patients was effective in decreasing the rate of surgical site infection during 3 years.

목적: 최근 indomethacin의 대체약으로 ibuprofen이 미숙아 동맥관 개존증의 예방과 치료에 사용되고 있다. 본 연구는 1,250g 미만의 미숙아를 대상으로 ibuprofen의 예방적 치료 효과 및 임상 경과를 분석하고자 하였다. 방법: 2009년 11월부터 2010년 7월까지 본원 신생아 중환자실에 입원한 1,250 g 미만의 동맥관 개존증 환아 39명을 대상으로 후향적으로 의무기록을 조사하였다. Ibuprofen의 예방적 투여군(출생 후 24시간 이내에 ibuprofen 투여) 13명에 대해 재태연령과 출생체중을 과거 대응(historical match)하여 대조군 26명으로 분류하였고, 두 군의 동맥관 개존증 빈도, 임상 경과 및 합병증을 분석하였다. 결과: Ibuprofen을 투여한 예방적 투여군과 대조군 간의 동맥관 폐쇄율(69.2% vs 77.7%, P=0.825)은 유의한 차이가 없었고, ibuprofen 치료에 실패하여 동맥관 결찰술을 시행 받은 경우도 두 군간에 유의한 차이가 없었다(23.1% vs 30.8%, P=0.719). 약물과 관련된 부작용으로 위장관 천공이 발생한 경우는 예방적 투여군에서 더 많은 경향을 보였으나 대상수의 부족 등으로 통계적 유의성은 없었다(30.8% vs 11.5%, P=0.194). 뇌실 내 출혈(grade${\geq}$3) 및 다른 미숙아 합병증의 발생률도 두 군간 차이는 없었다. 결론: 미숙아에서 ibuprofen의 예방적인 투여가 동맥관 폐쇄율, 동맥관 결찰술 그리고 고도의 뇌실 내 출혈의 빈도를 감소시키지 못하였다. 향후 예방적 ibuprofen 사용과 관련하여 효과 및 부작용에 대한 더 많은 연구가 되어야 할 것이다.
