ascidian n.【動物；動物學】海鞘類動物。

ascidium
Considering of the specificity of the degenerative primer designed in this pcr reaction , the identity between the sequence we wanted and the fragment of pcr product and the presence of asmaspa , asmaspb , clr and cls ( the homologous gene of masp gene ) in halocynthia roretzi , a japanese ascidian , we believe that the sequence of pcr product is some part of the masp gene or masp homologous gene 基于本實驗中所設計的引物為特異性簡并引物，測序基因通過比較得到與預期片段有一定的同源性以及masp同源物asmaspa 、 asmaspb 、 clr和cls在海鞘中存在的事實，我們可以初步推測，本實驗pcr反應所克隆的片段可能為文昌魚masp或其同源基因的一部分序列。
According to the frequently used methods of extraction and isolation of natural products from organic body , the freeze - dried ascidian tunica was exhaustively extracted with 100 % chloroform then the combined extracts were filtered and the solvent was separately concentrated under vacuum to yield a dark - brown gum 按照目前比較常用的天然產物的提取分離辦法，將樣品冷凍干燥后，用100氯仿浸泡，收集氯仿濾液，減壓蒸餾濃縮去除浸提溶劑，得到黑褐色的浸膏狀物質。
During experiment , acetylcholine shows significant inhibitory effects on the settlement and metamorphosis of ascidian larvae , but its concentration cannot lower 1 x 10 - 7mol / l . similarly acetylcholine , y - aminobutyric ( gaba ) and picrotoxin also can inhibit the settlement and metamorphosis of s . canopus larvae 實驗中，乙酰膽堿對冠瘤海鞘的附著變態表現出抑制作用，但當濃度降低到10 ~ ( - 7 ) mol l時，此作用已不明顯。
We also found crude extracts of two sponges ( mycale sp . and renieera spi ) can inhibit the settlement and metamorphosis of ascidian larvae . the two extracts are all liposolube Spl ），它們的粗提物對冠瘤海鞘幼體的附著和變態有抑制作用，這兩種粗提物都是脂溶性的。
Furthermore , l - thyroxine do n ' t show any effects on the settlement and metamorphosis of ascidian larvae . 3 此外， l - thyroxine對冠瘤海鞘幼體的附著變態均未表現出顯著的促進或抑制作用。
H - 13 ( achromobacter ) . can facilitate the metamorphosis of ascidian larvae 無色桿菌屬的h - 13能誘導幼體變態。
