Different organic composts application in dryland Mollisol:Residual effect and soil CO emission.

Organic compost application plays an important role in improving the fertility of Mollisol. However, the effects of different organic composts on carbon sequestration varies greatly and its internal mechanism are unclear. We conducted a field experiment to explore the residual proportion of different organic composts and their effects on carbon emissions in dryland Mollisol in Northeast China.

[Clinical application of avidin-biotin ELISA to detect serum hepatoma-specific gamma-glutamyltransferase in patients with primary hepatic cancer].

Objective: To detect serum hepatoma-specific datura stramonium lectin-tightly binding gamma-glutamyl transferase (DSA-GGT) in patients with primary hepatic cancer (PHC) by avidin-biotin ELISA method which was established in our laboratory, and carry on a study of its clinical application.

Methods: To detect serum DSA-GGT in 45 healthy control subjects, 58 PHC patients and 203 non-PHC patients (including 36 patients with other tumors and 167 patients with benign liver diseases) with the method was established; meanwhile, AFP was detected by ELISA method.

Results: 38 individuals were DSA-GGT positive in 58 PHC patients, the sensitivity was 65.
