Endophytic fungi associated with Macrosolen tricolor and its host Camellia oleifera.

Endophytic fungi play an important role in terrestrial ecosystem, while little is known about those in hemi-parasitic plants, a group of special plants which absorb nutrients from its hosts by haustoria. The relationship of the endophytes in the two parts of the bipartite systems (hemiparasites together with their hosts) is also poorly understood. Endophytic fungi of a hemi-parasitic plant Macrosolen tricolor, and its host plant Camellia oleifera were investigated and compared in this study. M. tricolor contained rich and diversified endophytic fungi (H' = 2.829), which consisted mainly of ascomycetes, distributed in more than ten orders of four classes (Sordariomycetes, Dothideomycetes, Leotiomycetes and Eurotiomycetes) besides Incertae sedis strains (23.2 % of total). In addition, 2.2 % of isolates were identified to be Basidiomycota, all of which belonged to Agaricomycetes. Obvious differences were observed between the endophytic fungal assembles in the leaves and those in the branches of M. tricolor. The endophytic fungi isolated from C. oleifera distributed in nearly same orders of the four classes of Ascomycota and one class (Agaricomycetes) of Basidiomycota as those from M. tricolor with similar proportion. For both M. tricolor and C. oleifera, Valsa sp. was the dominant endophyte species in the leaves, Torula sp. 1 and Fusarium sp. 1 were the dominant endophytic fungi in the branches. The similarity coefficient of the endophyte assembles in the two host was 64.4 %. Canonical correspondence analysis showed that the endophyte assembles of M. tricolor and C. oleifera were significantly different (p < 0.01).

Research on the correlation between the temperature asymmetry at acupoints of healthy and affected side and the severity index of facial paralysis / 中国针灸

<p><b>OBJECTIVE</b>To observe the change trend of the temperature asymmetry coefficient at acupoints between healthy side and affected side in patients with facial paralysis, to study the correlation between the temperature asymmetry and Facial Disability Index (FDI), to provide scientific guidance for the application of infrared thermography in the examination of severity of facial paralysis.</p><p><b>METHODS</b>Using the infrared thermography to observe the temperature asymmetry at acupoints, the temperature asymmetry coefficient at acupoints between healthy side and affected side was calculated; the correlation between the temperature asymmetry and FDI was analyzed.</p><p><b>RESULTS</b>The correlation between the temperature asymmetry coefficient and FDI was statistically significant at acupoints of Yang-bai (GB 14), Cuanzhu (BL 2), Dicang (ST 4), Yuyao (EX-HN 4), Quanliao (SI 18), Jiache (ST 6) (P < 0.05, P < 0.01).</p><p><b>CONCLUSION</b>The temperature asymmetry coefficient at acupoints between healthy side and affected side could be a scientific measure to evaluate the severity of facial paralysis.</p>
