Before fissuration, osmotic adjustment occurred by the addition of solute to cells and decreasing the loss of water in the body, so that it could maintain normal turgor pressure during drought. After fissurate growth, turgor pressure was maintained by higher cell and tissue elasticity lower ε(superscript max and by osmotic adjustment for normal plant development in dry conditions and to avoid dehydration under water stress during the drought period, but it also became more sensitive to water stress. The ability to maintain turgor pressure varied from strong to weak during the period before, during and after fissuration. Fissurate growth decreased the ability of P. mongolica to maintain turgor pressure and led to changes in walls related to drought tolerance.

结果表明：1未劈裂绵刺主要通过增加细胞内溶质，减少细胞内的水分丧失来进行渗透调节，从而在干旱胁迫下能够维持正常的膨压。2己劈裂绵刺通过渗透调节和高的组织弹性两条途径来共同保持膨压，以抵抗不良的生存环境；同时对环境水分胁迫具有较高的敏感性。33种状态绵刺保持膨压的能力由强到弱依次为：未劈裂绵刺、正在劈裂绵刺、已劈裂绵刺。4劈裂的发生导致绵刺保持膨压能力的降低，同时耐旱方式和途径发生了变化。

METHODS: A model of T cell activation and proliferation was established by stimulated the cells with Con A.T cells were treated with different concentrations of CPT. The expression of CD69, the early marker of CD3(superscript +) T cell activation, was measured by FACS. The proliferation index was determined by carboxyl fluorescin diacetate succinmidyl ester by flow cytometry. The cell-cycle distribution was analyzed by propidium iodide staining.

以ConA刺激小鼠T淋巴细胞，建立小鼠T淋巴细胞活化、增殖的模型，以不同浓度的CPT作用于该模型，流式细胞术检测T细胞早期活化标志CD69分子的表达；以活体染料羧基荧光素乙酰乙酸染色流式细胞术分析CPT在ConA刺激下小鼠淋巴细胞的增殖相关指数；以碘化丙啶染色流式细胞术分析细胞周期的分布情况。

METHODS: After stimulated with Con A, T cells were treated with different concentrations of TMB-8 alone and its combination with cyclosporine A. The expression of CD69, the early marker of CD3(superscript +) T cell activation, was measured by FACS. The proliferation-related index was determined by carboxyl fluorescin diacetate succinmidyl ester flow cytometry. The cell-cycle distribution was analyzed by propidium iodide staining.

以Con A作为T细胞活化、增殖的刺激剂，以不同浓度的TMB-8及与环孢菌素A联合作用于该系统，用流式细胞术检测T细胞早期活化标志CD69分子的表达；以活体染料羧基荧光素乙酰乙酸染色流式细胞术，分析TMB-8在Con A刺激下小鼠淋巴细胞的增殖相关指数；以碘化丙啶染色分析细胞周期的分布情况。
