| 1 | 双孢蘑菇在不同覆土层上的营养利用差异显示文摘用作双孢蘑菇覆土材料的 Cabutz(是牛粪经厌氧嗜热发酵降解后的固体部分)和泥炭可能是双孢蘑菇的营养物源。在真菌生长期间,两种覆土材料的导电性、PH、漆酶和内纤维素酶在不断变化,纤维素和木质素在降解。蘑菇生产中,Cabutz(不是泥炭)被双孢蘑菇分解利用,而不是其体积的功能才成为了好的覆土层。这些结论反驳了普遍赞同的观点,每一种好的覆土层都能释放出蘑菇能有效利用的营养物质。蘑菇栽培者通常知道为获得稳定的产量,蘑菇生长的堆肥必须用土壤覆盖。覆土在真菌形态发育过程中的作用是模糊不清的。当然对理想的覆土常用一些化学、物理和微生物系数来估计它对子实体产量增加的作用。 | Dan Levanon 贺新生 | 1988 | 西南科技大学学报(哲学社会科学版)1988，14，3： | 2 |

| 5 | Intrahepatic CD8^+ lymphocyte trapping during tolerance induction using mushroom derived formulations:A possible role for liver in tolerance induction显示文摘AIM: To determine the immunomodulatory effect of Shiitake (a mushroom extract),we tested its effect on liver-mediated immune regulation in a model of immune-mediated colitis. METHODS: Four groups of mice were studied. Colitis was induced by intracolonic instillation of TNBS in groups A and B. Groups A and C were treated daily with Shiitake extract,while groups B and D received bovine serum albumin. Mice were evaluated for development of macroscopic and microscopic. The immune effects of Shiitake were determined by FACS analysis of intra-hepatic and intrasplenic lymphocytes and IFN-γ ELISPOT assay. RESULTS: Administration of Shiitake resulted in marked alleviation of colitis,manifested by signifi cant improvement in the macroscopic and microscopic scores,and by reduction in IFN-γ-producing colonies in group A,compared to group B mice (1.5 pfu/mL vs 3.7 pfu/mL,respectively). This beneficial effect was associated with a significant increase in the intra-hepatic CD8+ lymphocyte trapping,demonstratedby an increased intrasplenic/intrahepatic CD4/CD8 lymphocyte ratio. These effects were accompanied by a 17% increase in the number of intrahepatic natural killer T (NKT) cells. A similar effect was observed when Shiitake was administered to animals without disease induction. CONCLUSION: Shiitake extract affected liver-mediated immune regulation by altering the NKT lymphocyte distribution and increasing intrahepatic CD8+ T lymphocyte trapping,thereby leading to alleviation of immune-mediated colitis. | Mony Shuvy Tiberiu Hershcovici Lidya Zolotarov Yaron Ilan Cristina LulI-Noguera Harry Wichers Ofer Danay Dan Levanon | 2008 | World Journal of Gastroenterology2008，14，24： | 0 |
