OBJECTIVE The present study was carried out to determine the antiinflammatory and antinociceptive activities of a methanol extract of Zingiber zerumbet rhizomes (MEZZ) using various experimental model systems. MATERIALS AND METHODS The MEZZ was prepared by macerating oven-dried (50 degrees C) powdered rhizomes (1.2 kg) of Z. zerumbet in 80% methanol in a ratio of 1:20 (w/v) for 48 h. The supe...

This paper describes a method for the isolation of strains of tobacco mosaic virus (TMV) which consist of infective particles that are labile under conditions where ordinary TMV is extremely stable. Two such strains have been isolated, PML and PM2, which are distinctly different in their properties. Evidence will be presented to demonstrate that tobacco plants infected with strain PM1 fail to s...
