The simulation result shows that vadose zone can rigorously retard those nuclides with vigorous adsorbility , i . e . the bigger the nuclide decay coefficient is , the more the nuclide is retarded in vadose zone and the less the nuclide concentration in aquifer is , and that the distribution coefficient directive affects the form of the nuclide concentration curve in an aquifer 數值模擬結果表明:包氣帶對于吸附性較強的核素具有很大的阻滯作用,對于低分配系數的核素阻滯作用較弱;衰變系數對含水層中核素的遷移起到了重要作用,隨著衰變系數的增大,地下含水層中的核素體積濃度逐漸降低,并且分配系數的大小直接影響著核素在含水層中體積濃度分布曲線的形狀。 |

Liposome is an effective nuclide delivery agent for neutron capture therapy . in this paper liposomes containing encapsulated gadolinium complex were prepared and characterized . the influence of formulation factors such as ph , ionic strength , buffer , and storage time upon the stability of liposomes was investigated . the uptake rate constant and its concentration dependence of lgd in tumor cells were compared in vitro with that of gd complex itself . the results indicate that the uptake rate of lgd in tumor cells increases to eight times as much as that of gd - edta , but the release rate of gd from tumor cells containing lgd is remarkably lower than that from the tumor cells containing gd - edta . the results reveal that lgd would be a potential drug for neutron capture therapy of cancer 制備和表征了包埋gd - edta的脂質體,測定了ph ,離子強度,緩沖液組成及溫度對gd - edta脂質體的影響,比較了gd - edta脂質體和gd - edta被腫瘤細胞攝入的動力學曲線。結果表明, gd - edta脂質體在37和生理條件下最穩定,腫瘤細胞攝入gd - edta脂質體速率是gd - edta的8倍,而釋放gd的速率, gd - edta脂質體遠遠低于gd - edta ,這些結果提供了脂質體包埋gd - edta作為釓中子俘獲治療藥物的可能性。 |
