    Ethnobotanical Study of Rice Growing Process in Northeastern Thailand
    (University of Hawaii at Manoa, 2006) Mokkamul, Piya
    Thailand is a developing country that relies heavily on rice agriculture. Photographic techniques are an easy and efficient method for studying human activities, culture, traditions, ethnobotany, and ethnoeconomy. In this paper, photos are used to provide an ethnobotanical description of the rice growing process of rice farmers in Northeast Thailand, from preparing the rice fields to harvesting the rice. “One picture can speak a thousand words.”

    Conservation Status of Maianthemum Species in the Hengduan Mountains: A Case Study Analyzing the Impact of New Policies on Wild Collected Plant Species
    (University of Hawaii at Manoa, 2006) Ying, Meng ; Yongping, Yang ; Weckerle, Caroline S.
    Maianthemum G. Weber ex Wigg. (Liliaceae) is a popular wild vegetable in Southwest P.R. China, the consumption and trade of which has recently been stimulated by local government polices and increasing tourism. We interviewed 68 stakeholders in Northwest Yunnan to document uses, harvest methods and amounts, and locally perceived conservation status of the species. Mainly M. atropurpureum (Franch.) LaFrankie, an endemic of the region, is consumed and collected for trade. Harvest methods and amounts differ significantly between different regions. Major regional markets in Northwest Yunnan are supplied with plants collected around Fugong, Nujiang Prefecture, where the intensive harvest is facilitated by trucks. In Zhongdian, Diqing Prefecture, all harvest is transported by men and sold locally. Only collectors in the latter area perceive a decrease of population sizes in recent years. In that area Maianthemum is decreasing due to several factors, such as relative scarcity of the species, habitat destruction, harvest methods, and increasing demand by tourists. Thus, local harvest strategies, which allow a sustainable use of the populations, need to be developed.

    Traditional Thai Medicines Inhibit Helicobacter pylori in vitro and in vivo: Support for Ethnomedical Use
    (University of Hawaii at Manoa, 2006) Mahady, Gail B. ; Bhamarapravati, Sutatip ; Adeniyi, Bolanle A. ; Doyle, Brian ; Locklear, Tracie ; Slover, Christine ; Pendland, Susan L.
    In Thailand, traditional plant-based medicines have always been used to treat gastrointestinal ailments, including gastritis, peptic ulcer disease (PUD) and diarrhea. Since Helicobacter pylori (HP) is an etiological agent of PUD, we have used an ethnomedical approach for screening plant extracts as potential treatments for HP infections, including over 20 species from Thailand. International Memoranda of Agreement were established between UIC and Mahidol University in Thailand. Medicinal plants were collected, identified and extracted. Susceptibility testing was performed with 15 HP strains using the agar dilution procedure guidelines of the Clinical and Laboratory Standards Institute. In vivo studies included evaluating bacterial load, as well as acute and chronic inflammation in HP-infected Mongolian gerbils. Extracts of Curcuma longa L. and Boesenbergia rotunda (L.) Mansf. significantly reduced HP-induced gastric lesions, as assessed both macroscopically and microscopically in Mongolian gerbils. The treatments reduced acute and/or chronic inflammation in a prevention model of HP-induced gastritis.

    Insertions and Deletions: Evolution in the Assemblage of Vietnamese Food Plants
    (University of Hawaii at Manoa, 2006) Nguyen, My Lien Thi
    An analysis of taxa used and that are salient to Vietnamese in Hawai‘i compared with southern Vietnam reflects an evolution of the assemblage of food plants demonstrated by substitutions, insertions, and deletions of plant taxa. Replications occur as the Vietnamese in Hawai‘i have access to many similar plant taxa as those in Vietnam, possibly due to the location of Hawai‘i as a place where similar food plants can grow and due to a large Asian population. Food plant taxa were elicited from interviews and recorded during participant observations. The current scientific botanical nomenclature and taxonomic groupings, plant life form or part utilized, the southern and many northern Vietnamese vernacular names with diacritical markings, and the English and French translations are provided for over 200 food plants. An introduction to Vietnamese diacritical writing and vernacular botanical nomenclature is included.
