Results The UV-B treatment caused the declines of chlorophyll content, soluble protein content and water content of leaves, besides, dose-effect was existed. The decline of 30 μW/cm^2 treatment was bigger than that of 15 μW/cm^2 treatment. The influences of UV-B radiation on carotenoid content and anthocyanidin content were similar; the change trends were declined firstly then increased. The UV-B treatment with two doses restrained the electron transport of PSⅡ, particularly; the inhibitory effect was biggest after treated 2h, and then this effect was declined in 4, 6 and 8 h, so the dose-effect was existed. The UV-B radiation with two doses restricted photosynthetic rate and the inhibitory effect increased with the increase of treatment time. The high dose treatment caused huge damage to membrane system, while the result of low dose treatment was not obvious.

The experimental results show that the mean particle size of griseofulvin precipitated by RESS is smaller than 1, 0μm, narrow distribution and 95% fine particles is smaller than 1. 0μm. Increase of the pre-expansion pressure, the extraction temperature, the expansion chamber temperature, the spraying distance, the concentration of cosolvent and decrease of the nozzle diameter resulted in decrease of the particle size under the operating condition studied. Enhancement of the pre-expansion temperature resulted in increase of the particles size. The SEM of GF shows that the shape of original is atactic and a wide size distribution, but the microparticles obtained by RESS is reverse. Similar melting points and XRD patterns were observed for the original material and the precipitates obtained by RESS.

Using stereomicroscope, we observed the fracture line direction and location as well as the angle between the fracture line and the attrite plane. The data was compiled into statistics and analyzed. The results revealed that most of the vertical root fractures occurred in teeth with severe attrite crown and flat root. Numerous bucco-lingual oriented fractures occurred in the mesial root of molars, and we found three non-endodontically treated cases with mesio-distal oriented fractures in the palatal roots.
