Hypoxia induces the resistance of tumor cells[4];and the heterogeny of solid tumors result in the appearance of subpopulations of differentproliferative potency in the same tumor tissue, so that the target cells sensitive to cell cyclespecific drug are reduced.

目前有研究认为：实体瘤部分细胞缺氧和肿瘤组织的异质性可能是导致肿瘤对放疗和化疗产生耐受的主要原因之一，缺氧可以诱导肿瘤细胞对放疗和化疗的耐受性[4]，实体肿瘤的异质性可使同一瘤组织内具有不同增殖潜能的癌细胞亚群存在，导致细胞周期特异性化疗药物作用的靶细胞减少。

Meanwhile, the antibodies of VIP enhanced the activation of lymphocytes and the expression of CD68, SYP in sacculus rotundus.

采用抗SP抗体使SP作用受到抑制后，圆小囊组织中淋巴细胞活化分子、DNES细胞表达SYP和巨噬细胞表达CD68分子的量均出现一定程度的减少；而当VIP作用受到抑制后，圆小囊组织中淋巴细胞活化分子、DNES细胞表达SYP和巨噬细胞表达CD68分子的量均出现一定程度的增多。

From the tests,we have obtained some structural variant features related with salt resistance and demonstrated the successful introduction of Rhizophora apicularta DNA into tomato.This thesis contains two parts. In the first part,the morphological and anatomical structures of the leaves were investigated. As to the morphology,some difference between control and transformed tomato were found. The leaf dimensions of the transformed tomato with unextended leaves were smaller than that of control. These structure changes should help to decrease the evaporation of water effectively and release the physiological drought resulted from saline.

本实验分两部分：第一部分、对转化番茄的形态及细胞显微结构进行观察与分析，实验表明转化番茄形态与对照相比有明显的变化，其叶面积变小，叶形收拢，这种结构可有效地减少水分的蒸发，缓解由盐胁产生的生理干旱；组织解剖结构结果显示，耐盐番茄在细胞结构上发生了明显的变异：其气孔器倾向下陷，表皮毛增多，叶脉微管组织不发达，微管束周围出现增多的贮水细胞，叶缘及其它部位表面分化出大型的多细胞分泌型结构，这些结构与转化番茄后代较强的耐盐能力有关。

The inflammation reaction hyperplactic stage and lymphatic nodular stage are of nonspecific morphological changes and should be diagnosed with the help of positive tuberculin test and obvious increase of adenosine deaninase ; tuberculous nodular stage has a great number of epithelioid cells,and Langhans cells, caseous necrosis stage is characterized by a great deal of necrotic tissue and debris,a small number of fragmented epithelioid cells, and mainly by antiacid bacteria fibrinous hyperplastic stage is featured by a few fibrous tissue, cells and mucous oweing to hardness to get puncture, which neans tuberculous restoration,and scar formation.

炎性增殖反应期非特异性形态学变化，需要结合结核抗体阳性和腺苷酸脱氨酶明显增高有助于诊断，结核结节期主要可有较多类上皮样细胞及郎罕氏细胞；而干酪样脓样坏死主要见大量坏死组织及碎屑、少数残碎不全类上皮样细胞，此期主要能查到抗酸菌为特征；纤维增殖期，抽出物难取，仅见少数纤维组织、纤维细胞和黏液间质为其特征，提示结核恢复、瘢痕形成所致。
