A microscopic fluorescence spectrometric analysis ( MFSA) system was set in the laboratory. A novel method for in situ determination of Anthracene ( Ant) adsorbed onto root surface micro-zone of two kinks of mangrove plant, named Kandelia obovata ( K. obovata) and Avicennia marina ( A. marina) by MFSA was established. Fluorescence spectra of Ant adsorbed on root surface micro-zone were obtained by synchronous scanning mode. The signal to noise (S/N) of Ant (5. 3 pg/μm2) adsorbed on K. obovata and A. marina root surface micro-zone increased up to 5. 5 and 6. 8 while wavelength offset (△λ) both were at 60 nm, respectively. The linear dynamic ranges of established method were 5. 3-63. 2 pg/μm2 for K. obovata and 10. 5-52. 6 pg/μm2 for A. marina, with the detection limits of 1. 1 pg/μm2 and 5. 5 pg/μm2 , respectively. The relative standard deviations were both less than 12 . 5% ( n=9 ) , and the recoveries were 98 . 1% -117. 0% and 81. 2%-110. 9%, respectively. The result showed that the MFSA system had ability to obtain quantitative information of fluorescence spectra and fluorescence image of Ant adsorbed onto plant roots surface micro-zone.

BACKGROUND:Many studies have shown that matrix metal oproteinases 1, 3, 9 and 13 play an important role in articular cartilage degeneration and destruction, but there is less special research on the articular synovium. OBJECTIVE:To observe the effect of long-distance running on the expressions of matrix metal oproteinases 1, 3, 9 and 13 in the synovium.
METHODS:Fifteen male Wistar rats were divided into three groups:control group, tablet group and uphil group. Rats in the control group received ordinary captivity;rats in the tablet group ran on the horizontal treadmil (0°) at the speed of 1 km/h for 1 hour daily, and lasted for 45 days;rats in the uphil group daily ran on the horizontal
treadmil (0°) at the speed of 1 km/h for 1 hour, and lasted for 15 days, and then the rats ran on the uphil treadmil (+20°) at the speed of 1 km/h for 1 hour daily and lasted for 30 days. The knee joint synovium injury models with varying degrees were established. The dual hind knee joints were obtained after modeling for paraffin-embedded. Then the overal sagittal slices were obtained for hematoxylin-eosin staining and immunohistochemical staining, and the experimental results were observed and analyzed.
RESULTS AND CONCLUSION:After long-distance running, the expression of matrix metal oproteinases 1 in synovium of the tablet group and uphil group was increased when compared with that of the control group (P<0.05), but there was no significant difference between tablet group and uphil group (P>0.05). There was no significant difference in matrix metal oproteinases 3 expression (P>0.05). The expressions of matrix metal oproteinase 9 and
matrix metal oproteinase 13 in synovium were in gradient increasing state (P<0.05), which were lowest in the control group, increased in the tablet group and highest in the uphil group. The results indicate that long-distance running
exercise can influence the normal physiological structure of rat knee joint synovium by changing the expression of matrix metal oproteinases.
