Objective To evaluate the effects of meglumine diatrizoate mucilage (MDC) used as contrast medium in bronchography. Methods A total of 500 patients undergoing bronchography were reviewed, including male 346, female 154, with an average age of 42 (ranged 5~71). Among them, 415 were examined with bilateral bronchography in a dose of 20~30 ml, 85 with unilateral bronchography in 10~15 ml of MDC. Results In 487 cases (97.4%), the lobes, segments, subsegment bronchi were revealed very well, and 456 cases (91.2%) had no cough. Conclusion MDC is regarded as an ideal bronchial contrast medium, and may replace dionosil and iodized oil.

Objective To understand the molluscicidal effects of water extract of Ginkgo biloba's peel on Oncomelania hupensis Methods Immersion methods with a series of six concentrations from 0.3 percent to 3 percent were used to determine the molluscicidal effect. Results The LC 50 of the water extract of 1.0 percent was 28.8 mg/L for 24 hours immersion,12.6 mg/L for 48 hours,and 0.48 mg/L for 72 hours, respectively. The LC 50 of the extract of 2 percent was 19.9 mg/L for 24 hours,11.2 mg/L for 48 hours and 0.48 mg/L for 72 hours,respectively.The LC 50 of the extract of 3 percent was 19.1 mg/L for 24 hours,10.9 mg/L for 48 hours and 0.48 mg/L for 72 hours,respectively. The higher of the concentration, the better of the effect. Meantime, it's poisoning to crops and fishes was very low. Conclusion Ginkgo biloba's peel has molluscicidal effect. It is a good candidate of potential plant molluscicides.
