[Methods] Animal models of the ACL reconstruction in 18 healthy F/M New Zealand White rabbits (2-3 months old) were made using extensor digitorum longus tendon and randomly divided into 3 groups-Group remnants debridement,Group remnants preservation and Group remaining bundle preservation.

Dynamics of bound residues of metsulfuron-methyl in soil humus;

Distribution of bound residues of metsulfuron-methyl in soil combined humus;

Bound Residue and Its Bioavailability of Different Aromatic Ring ~(14)C-Labelled Herbicide ZJ0273 in Aerobic Soils;

Interaction of pesticide and its metabolites with soil inorganic or organic fractions may form bound residues through many ways in soil.

High temperature distillation (HTD) and supercritical fluid extraction(SFE) methods were used to extract 14 C chlorsulfuron bound residues from soil.

In order to investigate effects of bound residues of metsulfuron-methyl(BR) on the activities of soil enzymes, the activities of urease, acid phosphatase, catalase, and sucrase were determined in Huangfentu(rice soil)spiked with bound residues of metsulfuron-methyl for 98 days.

The purpose of the present study was to investigate 14 C extractable residue( 14 C ER), 14 C bound residue( 14 C BR)and mineralization of 14 C labeled metsulfuron methyl in soils.

The purpose of the present study was to investigate 14 C extractable residue ( 14 C ER), 14 C bound residue( 14 C BR)and mineralization of 14 C labeled chlorsulfuron in soils by using isotope technique.
