Flow cell metric (FCM) analysis found: accumulation of cells of G_1 stage. Ultrastructure study disclosed: swelling of mitochondria in cytoplasm and damage of mitochondrial crests even with cavity formation, enlargement and degranulation of rough ER. It seemed the effect of LBGO was affirmable. It was postulated that macrophages,being activated by LB, came in close contact with the cancer cells giving rise to carcinolysis. In addition to the direct but transient killing effect of GO, the anti-cancer results could be greatly enhanced.展开更多

The resuits showed that the thylakoid in chloroplast was orderly and clearly as soybean leaves were pretreated by La（Ⅲ）. The thylakoid was indis- tinctly disordered, expanded and even indiscoverable in the chloroplast under UV-B stress. The impact on the thylakoid by the high intensity UV-B irradiation （T2） was bigger than that by the low intensity UV-B irradiation （T1）. However, the destruction of the chloroplast structure caused by UV-B stress was alleviated by La（Ⅲ）, and the arrangement of the thylakoid in the chloroplast became orderly and clearly. The effect of the alleviation by La（Ⅲ） under the low intensity UV-B irradiation （T1） was better than that under the high intensity UV-B irradiation （T2）.展开更多
