| 1 | Phytochemical and anti-bacterial activity of epidermal glands extract of Christella parasitica (L.) H. Lev.显示文摘Objective:To study the morphology,biochemistry and bioactivity of the epidermal glands of the glandular morphotype of Christella parasitica(C.parasitica)(L.) H.Lev.Methods: Morphological studies on epidermal glands were earned out by using light microscope and scanning electron microscope.To prepare the extract,the shade-dried fronds of glandular morphotype were soaked in acetone.For antibacterial studies paper disc method was followed by using various pathogenic bacteria.Results:Detailed micromorphological,phytochemical and bioactivity studies on a medicinal fern C.parasitica(L.) H.Lev.showed its inlraspecific variation in antibacterial activity.The presence or absence of the epidermal glands was the key factor for antibacterial activity in the morphovariants of this species.The epidermal glands were orange-coloured,stalked and elongated ones of about 84.2μm×45μm,and distributed on the undersurface of cosla,coslules and veins in croziers,young and mature leaves.Frequency of glands varied from 15/cm on costa in mature leaves to 140/cm on costules in croziers.The acetone extract of the glands showed antibacterial activities and also toxic effect against mosquito larvae and tadpoles of frog.Preliminary phytochemical analysis and HPLC studies of the gland extract showed the presence of various kinds of terpenoids,alkaloids,tannins,saponins and flavonoids in it.Conclusions:The present study shows that epidermal glands of the glandular morphotype of C. parasitica(L.) H.Lev.have several bioactive compounds and such rare moiphovariant should be conserved in nature.The next step is to isolate the pure compounds and to screen the bioactivity of individual compounds of the epidermal glands. | Paul Raj K Irudayaraj V Johnson M Patric Raja D | 2011 | Asian Pacific Journal of Tropical Biomedicine2011，1，1： | 14 |
| 2 | Risk of colon cancer in hereditary non-polyposis colorectal cancer patients as predicted by fuzzy modeling:Influence of smoking显示文摘瞄准:为了调查一个模糊逻辑模型是否能预言肤色,表面的癌症(CRC ) 风险由在世袭 non-polyposis 肤色吸表面的癌症(HNPCC ) 病人产生了。方法:从 Creighton 大学世袭癌症研究所登记的 340 个 HNPCC 失配修理(MMR ) 变化搬运人为当模特儿被选择。年龄依赖者曲线被产生阐明开发 CRC 的概率上的在基因变化(hMLH1 或 hMSH2 ) 之间的联合效果,性,和吸烟地位。结果:在男 hMSH2 变化搬运人的吸烟显著地增加的 CRC 风险(P <
0.05 ) 。hMLH1 变化为男性相对 hMSH2 变化搬运人扩充了 CRC 风险(P <
0.05 ) 。男性们非为 hMLH1 比女性有 CRC 的显著地更高的风险吸烟者(P <
0.05 ) , hMLH1 吸烟者(P <
0.1 ) 并且 hMSH2 吸烟者(P <
0.1 ) 。以在在男性的 hMSH2 的一种剂量依赖者方式的吸烟支持的 CRC (P <
0.05 ) 。有 hMSH2 变化的女性和与 hMLH1 组一起的两性仅仅在广泛的吸烟历史以后表明了吸烟效果(P <
0.05 ) 。结论:由在 HNPCC 病人吸烟的 CRC 提升依赖于基因变化,性和年龄。这些数据证明模糊建模可以启用临床的风险分数的明确的表达,从而允许 CRC 预防策略的 individualization。 | Rhonda M Brand David D Jones Henry T Lynch Randall E Brand Patrice Watson Ramesh Ashwathnayaran Hemant K Roy | 2006 | World Journal of Gastroenterology2006，12，28： | 5 |
