Nuclear DNA content analysis revealed that hybrid plants had different nuclear DNA content:higher,lower than the parental sum or equal to it.Contrast to the lower and equal hybrids,bigger amount of hybrids with higher DNA content had abnormal leaf,bad growth vigour and poor fertility.

结果表明：杂种形态变异广泛，多数呈中间类型，少数呈偏亲性状；杂种细胞DNA含量不一致，呈现大于、等于、小于双亲细胞DNA含量之和的类型；DNA含量大于双亲之和的杂种与DNA含量等于或小于双亲之和的杂种相比，有较高比例的材料叶型出现畸形和植株生长势弱，育性也更差。

The human bile duct carcinoma cell line QBC_(939) was neurotropic. The co-culture model of DRG/nerve cell and carcinoma cells could simulate the process of the tumor cell going through the matrix and invading the nerve fiber.

结论DRG/神经细胞-肿瘤细胞共培养模型较好的模拟了肿瘤细胞穿过细胞基质，浸润神经纤维的过程，人胆管癌细胞QBC939细胞对神经纤维具有亲嗜性。

Copper pyruvaldehyde bis（N -methylthiosemicarbazone） complex, or Cu-PTSM, belonging to a class of neutral, lipophilic complexes ,is a positron emission tomography radiopharmaceutical that can be used to evaluate blood flow in the heart, brain, and tumors without following any side effect .

Cu-PTSM是中性亲脂性复合物，用于PET显像的放射性药物由于该制剂很容易扩散到细胞内，因此注射Cu-PTSM后可以了解心、脑和肿瘤部位的血流灌注状况，它不伴有副反应的发生，且合成比较容易，所以是一种非常有途的新型PET显像剂。

The duodenal juice mainly consists of the bile acid, which is a sort of lipophilic steroid and may result in direct injuries of mucosal epithelial cells and their tight junctions. Some researches have showed that the bile acid directly damaged the chemical environment of mucosa surface and played a synergistical role in gastric mucosal lesions along with gastric acid and H.

十二指肠反流液中主要成分为胆汁酸，胆汁酸是十二指肠反流液中造成黏膜损伤的主要成分，为一种亲脂性类固醇，直接破坏黏膜上皮细胞以及细胞间的紧密连接，同时还对腔内及黏膜表面的化学环境造成直接的影响，增强胃酸、H。

Glutathione S-transferase, an important detoxification enzyme in mammalian cells, canalizes the conjugateion of GSH with electrophilic xenobiotics to facilitate their excretion from the body.

Glutathione S-transferase 为哺乳动物细胞中一重要的解毒酵素，它可以催化GSH与攻击DNA的亲电性外来物质结合，并将之代谢排出体外。

I didn't watch TV last night, because it .
