It was incandesced at various temperatures and modification effect was compared. The results showed that optical absorption of sample incandesce at 423K occurred significant red-shift. Light absorption width extended from ultraviolet region to visible region, especially there was an intensive absorption between 600 nm and 680 nm. X-ray diffraction spectrogram showed that TiO2 in sample still maintained anatase crystal form. Under the illumination of visible light, photocatalysis degradation experiment was taken with Eosin B as simulated pollutants. Decoloration rate of Eosin B was much improved. The rate can reach 80% in 300 minutes.展开更多

METHODS： A model of oligoasthenospermia was induced in 50 Sprague Dawley rats by treatment with tripterygium glycosides at 30 mg/kg per day for 8 weeks. They were divided randomly into a model group, a positive group （Huangjingzanyu capsule, 3.01 g/kg）, and low, medium and high dose Wuziyanzong treatment groups （2.30, 4.60, 9.20 g/kg crude drug respectively） with 10 in each group. Another 10 rats were used as a control group. The rats in the control and model groups were administered distilled water, while the rats in the remaining groups were administered Wuziyan- zong for 30 d. The epididymides were removed, spermatozoa recovered and the sperm density and viability were measured. The spermatozoa were pu- rified and the contents of Ca2~ in the cytoplasm and mitochondria were detected by flow cytometry and atomic absorption spectrometry, respectively. RESULTS： After 8 weeks of treatment with tripteryg- ium glycosides, the sperm density, sperm activity and the Ca2~ content of spermatozoa in the model rats were all significantly decreased compared with the control group （all P〈O.05）. After 30 d treatment, the sperm density and activity improved and the Ca2＋ content of sperm were increased significantly in the medium and high dose Wuziyanzong treat- ment groups in comparison with the model group （all P〈O.05）. CONCLUSION： The Wuziyanzong treatment in： creased sperm density, improved sperm viability and enhanced the content of Ca2＋ in the sperm cy- toplasm and mitochondria in this rat model of oli- goasthenospermia.展开更多
