2 sRaw ABStrAct This study evaluated the anti-asthmatic activities of 2,6-di-tert-butyl-4- hydroxymethylphenol (DBHP) that is a potent phenolic antioxidant in edible veg- etable oil. The effects of DBHP on bronchial asthma were evaluated by determining the specific airway resistance (sRaw) and tidal volume (TV) during the immediate asthmatic response (IAR) and the late-phase asthmatic response... (sRaw) and tidal volume (TV) during the immediate asthmatic response (IAR) and the late-phase asthmatic response (LAR) in guinea pigs with aerosolized ovalbumin-induced asthma. Recruitment of leukocytes and the levels of biochemical inflammatory mediators were determined in the bronchoalveolar lavage fluids (BALFs), and histopathological surveys performed in lung tissues. DBHP significantly inhibited the increased sRaw and improved the decreased TV on IAR and LAR, and also inhibited recruitment... -

The effectsof a general property of syllable structure rather than language-particular forms are... This study aims to survey the child phonological systems and features. Phonological systems have been viewed as comprising rules for two types of phenomenon: segmental and suprasegmental. Segmental rules affect the presence of and precise phonetic feature values associated with individual consonant and vowel segments. Suprasegmental rules concern properties of pronunciation that typically affect constituents larger than the segment, particularly stress, intonation and tone. In this paper,...
