ABSTRACT To study the antibacterial constituents from the fermentation broth of endophytic fungus Penicillium sp. 0935030 from mangrove plant Acrostichum aureurm. The separation procedure was guided by antibacterial bioassay. Seven compounds were isolated and purified by column chromatography, and their structures were identified as cyclo (1), cyclo (2), 1(2Furanyl)1,2ethanediol (3),(3β,4β,22β)olean12ene3,22,23triol (4), mannitol (5), uridine (6), and liquiritigenin (7) by physicochemical and spectral data.

为研究红树林植物卤蕨内生真菌Penicillium sp.0935030发酵物中的抗菌活性成分，采用活性追踪的方法，用多种色谱技术对化合物进行分离纯化，通过理化性质和光谱数据鉴定出7个化合物，分别为：环(1)，环(2)，1呋喃基1，2乙二醇(3)，(3β，4β，22β)12烯3，22，23三羟基齐墩果烷(4)，甘露醇(5)，尿苷(6)和甘草素(7)。

They were two new compounds, [cyclo(Pro-Val-Phe-Phe-Pro-Val-Phe-Ser-Leu),7],[2-N-(1-methoxycarbonylethyl)guanosine, 10], and eight known compounds,(p-hydroxybenzoic acid, 1),(methyl succinate, 2),(russulaceramide, 3),(phenylalanine, 4),(guanine, 5),(β-carboline, 6),(uridine, 8), and (adenosine, 9). All the compounds were isolated from Amanita exitialis for the first time.

分别为：对羟基苯甲酸(p-hydroxybenzoic acid，1)、丁二酸二甲酯(methyl succinate，2)、神经酰胺(russulaceramide，3)、苯丙氨酸（phenylalanine，4）、鸟嘌呤核苷(guanine，5)、β-咔啉(β-carboline，6)、环（脯氨酸-缬氨酸-苯丙氨酸-苯丙氨酸-脯氨酸-缬氨酸-苯丙氨酸-丝氨酸-亮氨酸） [cyclo(Pro-Val-Phe-Phe-Pro-Val-Phe-Ser-Leu)，7]、尿嘧啶核苷(uridine，8)、腺嘌呤核苷(adenosine，9)、2-N-(1-甲氧羰基乙基)鸟苷[2-N-(1-Methoxycarbonylethyl)guanosine， 10]。10个化合物均为首次从致命鹅膏中分离得到，其中化合物7和10为新化合物。

Methods Using a combinatorial approach of enzymatic digestion and mechanical separation to allow isolation and culture of GER cells from P1 rat cochleae.

方法取生后1d大鼠耳蜗，利用机械分离和酶消化相结合的方法分离出纯GER细胞，分别于无血清和含10％胎牛血清的DMEM培基中进行培养，观察细胞生长特性，并对培养物进行溴脱氧尿苷、鬼笔环肽、Z01、钙视网膜蛋白及肌球蛋白VIIa免疫组化鉴定及扫描电镜观察。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
