RESUMO
A literature search of related articles was carried out in electronic data sources. Initially, 276 randomised controlled trials related to the title were collected, after which 44 were selected using the keywords. Overlapping articles, articles with a study duration of less than six months, and studies involving young participants were removed from the list. The remaining 20 articles were checked for entitlement using the PEDro scale. A total of nine eligible articles with 1486 participants were analysed. Seven trials used dual-energy x-ray absorptiometry (DXA) to measure bone mineral density (BMD). The six trials published from 2005 to 2013 found a significant increase in BMD. In the remaining one trial, there was no significant increase in BMD. One study published in 2013 reported a significant increase in BMD measured with peripheral qualitative computed tomography, whereas another trial published in 2014 stated that there was a reduction in calcaneal bone density measured by peripheral qualitative ultrasound. From these findings it can be concluded that the whole body vibration machine is a good adjunctive therapy for the prevention and management of osteoporosis in postmenopausal women. However, further investigations are necessary before the same can be recommended for elderly men.
RESUMO
Standard strains of enterotoxigenic Escherichia coli (ETEC) were used to raise "OK" and "O" antisera in rabbits. The antisera were obtained from 06k15, 08k40, 025k+, 027k+, 078k80, 0148k+ and 0159k+ strains. Random samples of 2730 isolates of E. coli from 305 cases of adults with diarrhoea or dysentery were tested with "OK" antisera by slide agglutination and found that 96 cases showed agglutination. It was then serotyped using "O" antisera by test tube serial dilution technique and found that 33 cases showed agglutination.
