Radiation synovectomy is one of the most useful methods for treating patients with refractory synovitis because of its convenience, long-term effects, repeatability and the avoidance of surgery. In this study, we investigated the toxicity, stability and biodistribution of a rhenium-188 ($^{188}$Re)-tin colloid to evaluate its suitability as a synovectomy agent. Twenty four hours after injecting the $^{188}$Re-tin colloids (74 KBq/0.1 mL) into the tail vein of ICR mice, most of the $^{188}$Retin colloidal particles was found in the lungs. In addition, there were no particle size changes at either room temperature or at $37^{\circ}C$ after injecting the $^{188}$Re-tin colloids in human plasma and synovial fluid. In vitro stability tests showed that the $^{188}$Re-tin colloid remained in a colloidal form without a critical size variation over a 2-day period. We investigated the leakage of $^{188}$Retin colloids from the intraarticular injection site with gamma counting in New Zealand white rabbits. The $^{188}$Re-tin colloids (55.5 MBq/0.15 mL) were injected at the cavum articular and the mean retention percentage of the $^{188}$Re-tin colloid was 98.7% for 1 day at the injection site, which suggests that there was neither change in the particle size nor leakage at the injection sites. In the biodistribution study with the SD rats, the liver showed the highest radioactivity (0.0427% ID/organ) except for the injected knees (99.49%). In the SD rats, mild toxicities including the skin or a synovium inflammation were observed as a result of a radioactivity of 15 mCi/kg at the intraarticular injection site. However, there was no systemic toxicity. In the Ovalbumin (OVA)-induced arthritic rabbits, the $^{188}$Re-tin colloid improved the macroscopic, the histological score and reduced the knee joint diameter when compared to the arthritic control. In conclusion, a $^{188}$Re-tin-colloid is considered as a strong candidate for radiation synovectomy with a superior efficacy and safety.

포장에서 농약 살포액의 조제, 살포 등의 작업을 수행하는 농작업자는 피부노출, 호흡노출경로를 통해 농약에 노출되며, 이러한 상황에서의 농약 노출에 대한 합리적인 위해성 평가를 위해서는 해당 영농상황에서 노출량을 정량적으로 측정해야 한다. 농약 노출 측정방법으로 patch, 장갑, 양말, 마스크를 이용하는 방법과 호흡 노출은 주로 고체흡착제와 공기흡입펌프가 연결된 personal air monitor를 사용하는 것이 좋을 것으로 판단된다. 이 농작업자의 정량적 피부 노출 측정법으로 유효할 것으로 판단된다. 노출 재료에 침착/부착된 농약량이나 고체흡착제에 포집된 농약량을 신체 전체에 대한 농약 노출량으로 외삽하기 위한 EPA 자료를 대체할 수 있도록 한국 사람의 표준 신체표면적 및 호흡률을 제안하였다. 중요한 노출 인자인 피부노출의 의복 침투율과 피부 침투율, 그리고 호흡노출의 침투율을 UK-POEM과 관련된 연구결과를 참고하여 다양하게 제안하였다. 노출 평가를 위한 살포 시간은 노출 측정 재료에 침착된 농약이 분석이 될 만큼 충분한 농약이 포집될 수 있도록 살포시간이 충분해야 하는데, 국내의 SS기나 동력분무기의 경우는 1반복 당 모두 약 20~40분에 살포(약 0.1~0.2 ha)로 해서 3반복 측정 결과를 4시간으로 환산할 것을 제안하였다.

This study was conducted with 478 farm households located in Pyongtaek Gun of Gyonggi Do, Chongju City and Chongwon Gun of Chung Buk Do, and Hongchon Gun of Gangwon Do for the period of 10, September through 20, October 1980. It dealt with general features of the farmhouseholds, their practices of handling and using pescides, and relationship between safe use of pesticides and poisoning experiences. The results of the study are summarized as follows: 1. Of the total, 63.2% purchased pesticides mainly through the Agricultural Coops, and 95.4% transported them home separately from other goods. 2 Pesticides were sold contained mainly in glass bottles and paper bags. 3. Mixing of the respodents (87.5%) stored pesticides in sheds, warehouses and boxes. 4. Mixing containers and measuring tools were not used by the majority of the group studied. This indicates that there exist serious problems of safety and accuracy with regard to use of pesticides. 5. As to pesticide protective devices, gloves, respirators, goggles and boots were not used in general. Even in case of using them, their quality was not satisfactory. 6. Among the interviewees, 4.2% did not read pesticide label, 33.9% did not wash immediately when pesticide was spilled on the skin, 48.4% did not care the wind direction during pesticide application, and 17.0% did not wash hands when smoking a cigarette while pesticide is being handled. 7. Of the total, 40.4% were found to harvest vegetables within 10 days from the date of pesticide application, which indicates their unawareness of possible hazards by pesticide residues. 8. Empty pesticide containers or bags were not properly disposed of by majority of the respondents. Furthermore, impacts on the environment by the misuse or abuse of pesticides were not understood by 67.6% 9. Of the interviewees, 48.7% were found to have not received instructions on safe use of pesticides. 10. The rate of pesticidal poisoning experience was about 28.0% if minor symptoms excluded, and it rose to about 44.0% if included. Meanwhile, the rate of pesticidal poisoning tends to increase with the size of farm. 11. The study failed to show a statistically significant relationship between the rate of pesticidal poisoning and use of mixing container and/or measuring tools. However, use of gloves showed a statistical significance on the rate of pesticidal poisoning. 12. Among the poisoned cases, 19.0% were cared for in either hospitals or clinics.

Objectives: Bee Venom has been used to relieve pain and to treat various diseases, such as arthritis, cancer and skin disease. Although Bee Venom has used extensively in gynecological fields, we don't have enough evidence with it. This study is to investigate efficacy and safety of Bee Venom on women by investigating papers, then we are going to suggest the direction of research. Methods: We searched for papers which had Bee Venom from Pubmed, OASIS, Journal of Korean Obstetrics & Gynecology, Journal of Korean Medicine up to August 2017, then classified according to the type of studies. Results: Eleven papers have been finally selected. One paper was a case report about atypical squamous cells of undetermined significance. Four papers were in vivo studies about 1 endometriosis and 1 polycystic ovarian syndrome and 2 human cervical cancer. Among eight papers that were in vitro studies, four papers were reported about ovarian cancer and four papers reported about human cervical cancer. Among ten papers that were experimental studies, two papers have been studied both in vivo and in vitro. Most of studies have shown that Bee Venom is useful for gynecological disorders. Conclusions: It has been identified that Bee Venom could be a good treatment for female disorder. However, more clinical reports and well-designed studies will be needed.
