Tuberculosis respiratory isolation

In the course of a search for a-glucosidase inhibitors, Kitaoka et al. found that such inhibitors are present in some Thai traditional crude dmgs [39]. For example, a-HNJ occurs in Non tai yak at a level of 0.1 % (dry weight). The Non tai yak sample is known to be Stemona tuberosa (Stemonaceae), which has been used in China and Japan for various medicinal purposes. In particndar, an extract from the fresh tuberous roots of S. tuberosa is used to treat respiratory disorders, including pulmonary tuberculosis and bronciiitis, and is also recommended as an insecticide [27,40,41]. In 2005, re-examination of polyhydroxylated alkaloids in S. tuberosa led to the isolation of thirteen alkaloids, 1, 24,25,31,36,37 (0.1 % of dry weight), 38,40,41,... 

The purpose of the tuberculosis control plan is to prevent the transmission of tuberculosis (TB), which occurs when an individual inhales a droplet that contains Mycohacterium tuberculosis. M. tuberculosis is aerosolized when an infected individual sneezes, speaks, or coughs. Transmission of TB and exposure to TB can be greatly diminished with early identification and isolation of patients at risk, environmental controls, appropriate use of respiratory protection equipment, education of laboratory employees, and when necessary early initiation of therapy.
