phygmomanometers are frequently contaminated with bacteria and are implicated in the transmission of microbes. A pilot study was conducted to determine the effectiveness and feasibility of using a physical barrier device in reducing rates of microbial contamination of sphygmomanometer cuffs. Blood pressure recordings were made with and without a disposable plastic device on healthy individuals to ensure that it did not interfere with the accuracy of readings. Baseline rates of microbial colonisation of sphygmomanometer cuffs were obtained over a six week period. For six weeks the device was applied to patients’ arms before measuring blood pressure, and sphygmomanometer cuffs were recultured during the intervention period. No difference was found in blood pressure recordings with and without the device. No difference in rates of bacterial contamination was observed during the intervention phase of the study. A disposable plastic device acting as a physical barrier may not reduce surface contamination of sphygmomanometer cuffs.

Abstract Aim Dental impressions are potential sources of bacterial contamination which could eventually lead to transmissible infectious diseases through the blood or saliva. Sodium hypochlorite is an effective disinfectant recommended by the American Dental Association (ADA) in a 1:10 dilution for a ten minute immersion to disinfect irreversible hydrocolloid impressions. As the ADA protocol is sometimes neglected in busy practice settings, this pilot study was designed to determine an efficient and effective protocol for disinfection of irreversible hydrocolloid impressions. Methods and Materials Various concentrations of sodium hypochlorite and disinfection times were challenged against irreversible hydrocolloid impressions contaminated with six Gram-positive and Gram-negative bacteria. Results A two minute immersion time in a 0.6% solution of sodium hypochlorite protocol was found to prevent bacterial growth on the impressions. Conclusion Disinfection of irreversible hydrocolloid impressions in a 0.6% solution of sodium hypochlorite for two minutes was as effective as the ADA's protocol of using a 0.5% sodium hypochlorite solution for ten minutes to destroy the test bacteria.

Monitoring Study

In recent years, Mongolia's river water has been heavily polluted by human activities, mining, industrialization, and other factors, and the river's flow has been declining every year, conducted a pilot study to monitor the study. The water sample contains an average of 0.7 million cells/ml of bacteria, which indicates low bacterial contamination. Усны биологийн бохирдлын мониторингийн судалгаа Сүүлийн жилүүдэд Монгол орны гол мөрний ус хүний буруутай үйл ажиллагаа, уул уурхай, үйлдвэржилт болон бусад хүчин зүйлээс болж маш их бохирдож, голын урсац жил бүр багасч байгаа тул мониторингийн туршилт судалгааг хийлээ. Усны дээжинд дунджаар 0.7 сая эс/мл бактери агуулагдаж байгаа нь нянгийн бохирдол багатай байгааг илтгэж байна.  Түлхүүр үг: тэжээлт орчин, морфологи, физиологи, мониторинг
