| 1. | Inadequate cell nutrition around vessels causes degeneration of tunica adventitia .
血管周围细胞的营养不足，引起外膜的变性。 |
| 2. | The epidermis arises from the tunica meristem
表皮来源于分生组织近外方的细胞。 |
| 3. | In this paper , we focus mainly on the chemical compound from the tunica of styela clava
实验中，我们单独对柄海鞘鞘囊中的化学成分进行研究。 |
| 4. | An orchiectomy was performed , and a 10 8 6 - cm mass , encapsulated within the tunica vaginalis , was resected
病理组织切片发现为一平滑肌肉瘤，且其?丸及副?均未受侵犯。 |
| 5. | The wall of digestive tube was composed of mucous membrane , thin submucosa , tunica muscularis and tunica adventitia , but duodenal gland in duodenum was not found
消化壁一般分为4层，由内向外为粘膜、粘膜下层、肌层和外膜，其中粘膜下层很薄，十二指肠粘膜下层无十二指肠腺。 |
| 6. | Ii . research on water - soluble constituent we also did some research on the water - soluble physiological active constituent from the tunica of styela clava
山东师范大学硕士学位论文柄海鞘生理活性物质的研究二、水溶性物质的研究我们还进行了柄海鞘鞘囊水溶性生理活性的研究。 |
| 7. | I . research on liposoluble constituent first , styela clava ' s tunica and its body were separated carefully so that interactions among some substances are prevented
一、脂溶性物质的研究首先，将柄海鞘的鞘囊和鞘体进行精细剥离，避免了物质的相互干扰，更好的进行物质的定位。 |
| 8. | 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
按照目前比较常用的天然产物的提取分离办法，将样品冷冻干燥后，用100氯仿浸泡，收集氯仿滤液，减压蒸馏浓缩去除浸提溶剂，得到黑褐色的浸膏状物质。 |
| 9. | Under the electric microscope , there is abundant rough endoplasmic reticulum ( rer ) , golgi complex and mitochondria in the cytoplasm of the chief cell , but there is also some smooth endoplasmic reticulum ( ser ) and microtubule in the cytoplasm . so we support the view that this type cell secretes the digestive enzyme and hydrochloric acid ( hcl ) . there is not tunica muscularis mucosae and intestinal gland in the small intestine
电镜下，胃底腺主细胞里有分泌颗粒，有丰富的线粒体、高尔基复合体和粗面内质网，也有细胞内分泌小管和滑面内质网，故其应相当于哺乳动物胃腺的主细胞，但也兼有壁细胞的功能，可称之为壁-主细胞。 |
| 10. | Nowadays , research on the physiological active substances from the marine tunicates is in a high speed progress . but it hardly can be seen on papers that some tunicate extracts which have high effective anticancer potential are obtained from styela clava " ? , tunica and body or other kinds of substances
目前，国外对海洋被囊动物海鞘生理活性物质的研究正处于高速发展阶段，但是关于来自柄海鞘鞘囊或鞘体的高效抗肿瘤提取物以及具有其它生理活性的海鞘提取物的仅有零星报道。 |
