ABSTRACT
<p><b>OBJECTIVE</b>To investigate the safe use of 10% difenoconazole in planting Gentiana scabra.</p><p><b>METHOD</b>The degradation dynamics of 10% ifenoconazole in the stems and leaves of G. scabra collecting in different time were determined by GC with ECD detection, and the half life of difenoconazole in the plant was calculated, and then the safe use method of 10% difenoconazole was formulated.</p><p><b>RESULT</b>Under the local climatic conditions, the half life of 10% difenoconazole was 6.84-6.90 days.</p><p><b>CONCLUSION</b>In the good agricultural practice (GAP) of G. scabra, the maximal concentration of 10% difenoconazole is 400 g x ha(-1), the safety interval of using 10% difenoconazole is 40 days.</p>

Aim The effect triptolide(Tri) on local stimulation was observed .Methods Tri solution in different concentrations was applied in rabbits, rats and mice and the respenses were observed .Results 1.11 ,2.22 and 4.44 mmol?L-1 of Tri induced obvious erythema and edema on both intact skin and injured skin of rabbits.The pathological histology revealed the evident inflammation in scarfskin and corium 2.22 mmol?L-1 and 4.44 mmol?L-1 of triptolide significantly induced swelling of auricle in mice.0.55 mmol?L-1 and 1.11 mmol?L-1 of Tri significantly induced swelling of planta in rats.The response of inflammation reached to peak at the third day after hypodermic injection and lasted a week.Tri also significantly induced pain reaction and enhanced the permeability of capillary after local injection in mice.Conclusion Tri has a local stimulation effect and induces inflammation which can not be antagonized by its anti-inflammation effect.
