Methods 56 patients in esophageal and gastric variceal bleeding were allocated randomly into the control group and the treatment group. All patients were given basic treatment, the CG patients received pituitrin (0.2U/min) though micro infusion pump,octreotide 0.1mg were injected in the TG patients and infused continuously at a rate of 25 礸/h. The efficient hemostasis, rebleeding, the average bleeding time and blood volume were recorded. Adverse reactions such as the queasiness, abdominal distension, abdominal pain, diarrhoea, palpitaition and hypertension were observed.

The dust was first mixed with NaBH4 powder to adjust the H/Cl ratio. Then, the sample was roasted at low temperature to promote the efficiency of dehalogenation/hydrogenation reaction. By way of Cl- titration, it was found that the roasting temperature (300℃~500℃), roasting time (5 to 25 minutes) and H/Cl ratio (6.0 to 20.0) would change the dissolution of Cl- from 0.0% to 17.5%. After caustic roasting and leaching of the dust, the zinc (17.4 g/l) and lead (1.6 g/l) recovery ratio were found to be 82.7% and 61.8% respectively.
