The experiments were realized in batch reactor and the isotherms were modelized by the Fowler-Guggenheim equation. During the adsorption process weak zeolite-sorbate interactions and more significant sorbate-sorbate attractions were identified. The adsorption was not linked to the molecular size of the sorbates and a strong correlation was established between the adsorption compound was the best adsorbed. The removal performances capacities and the dipole moments of the sorbates. The most polar of the zeolites depended on their hydrophobicity.展开更多

The corresponding adsorption capacity of immobilized ssDNA immunoadsorbent for IgGRF was enhanced from 46% to 86%, This result indicates the tryptophan residue is essential for the interaction between ssDNA and IgGRF .and ionic-bonding plays an important role in adsorption.展开更多

Methods: After establishing the RA rats model, the induced rats were treated with moxibustion therapy on the acupoint Shenshu (BL 23) and Zusanli (ST 36), followed by analyzing the pathological section of the ankle of the hind limb and testing the ICAM-1 content with ELISA. Results: The plantar circumferences of the induced rat increased significantly compared with the rats in the control group (P〈0.01), accompanying with the increase of the synovial layer, the erosion of phlogocytes to chondrocytes and the specific increase of ICAM- 1 content. After the moxibustion therapy, the plantar circumferences decreased significantly (P〈0.01) while the synovial layer tended to reduce. In addition, there was no pathological damage of the articular cartilage and the ICAM content decreased with significant deviation (P〈0.01), compared to the model group. Conclusion: It was concluded that moxibustion therapy could inhibit the arthrosynovitis and hyperplasia, ameliorate the erosion of phlogocyte to cartilage, prevent articular periosteal lesions and delay the pathological course. The warming and activating effect of moxibustion therapy may involve the inhibition of the formation of ICAM- 1 and pannus.展开更多
