Anti-feeding effect of total ginsenoside from Panax ginseng on Heliothis dipsacea larvae / 中国中药杂志

<p><b>OBJECTIVE</b>To study the anti-feeding effect of total ginsenoside of ginseng stems and leaves on Heliothis dipsacea larvae.</p><p><b>METHOD</b>The natural growing condition for lavae was simulated indoors. The anti-feeding effect of total ginsenoside on Heliothis dipsacea larvae was studied by leaf disc test.</p><p><b>RESULT</b>The total ginsenoside appeared showed a significant antifeeding effect. The Heliothis dipsacea larvae fed with the leaves of soybean treated with 2.0%, 1.0% and 0.5% total ginsenoside, respectively. At 8 h, non-selective anti-feeding rate were 93.40%, 83.42% and 75.19%, and selective anti-feeding rate were 77.53% , 73.58% and 58.86%.</p><p><b>CONCLUSION</b>The toatal ginsenoside had significant inhibition effect on Heliothis dipsacea larvae, and inhibition effect increases as the increase of concentration ginsenoside.</p>

THE INFLUENCE OF ANTI-TUMOR DRUG, CHANG-BAI XIN KUI (长白新奎), ON THE ANAE POSITIVE LYMPHOCYTE OF MOUSE TUMOR MODEL PRODUCED BY S180 ASCITES CANCER / 昆明医科大学学报

The influence of Chang-Bai Xin kui(长白新圭) on the acid ?-naPhthyl acetate esterase(ANAE) positive lymphocytes was studied by using ANAE as a cytochemical marker.S180 cells ef ascites tumor were inoculated into the mice in experimental and control group. 3 days later, 0.8mg/0.2ml of Chang-Bai Xin Kni was injected peritoneally into the mice in experimental group everyday in 7 days. Eaeh of the two groups has its own self control.The experimental results show that there is no significant differences in total numbar of ANAE positive lymphoctes between the two groups and all self-controls.But after 7 days of injecting the drug, the granular pattern and scattered granular pattern of lymphoctes were increased significantly(P
