[Method] Based on the traditional method for paraffin sections preparation, steps including fixation, dehydration, adhering to slides and staining were investigated taking the structural characteristics of pine needles into considera-tion. [Result] 70% ethanol was used in the FAA fixative; before affixed on slides, the cut sections were first expanded in a 40 ℃ water bath and taken out by using Su-perfrost Plus slides, fol owed by drying in a 35 ℃ oven for 24 h; pine needles were cut into 8 μm thick sections; staining was achieved by immersion in eosin for 5 min and in hematoxylin for 1 min. [Conclusion] The conditions obtained above can en-hance the effect of fixation and dehydration; adhering to slides is easy to operate and the sections are not easy to drop; the dyeing effect is relatively preferable.展开更多

Methods: A total of 41 cases of appendicitis patients (24 males and 17 females) were subjected into this observation. Electroacupuncture (AA, 60-100 Hz, a bearable stimulus strength) of Pishu (BL 20), Weishu (BL 21), Zhangmen (LR 13) and Wushu (GB 27) was performed beginning 30 minutes before operation. Adjuvants used were luminal (100 mg, intra muscular injection), dolantin (1 mg/kg), 0.5% procaine (1-2 mL). Results: Of the 41 cases, the successful rate was 87.80% and the excellent plus good rate was 75.61% respectively. Conclusion: Acupuncture anesthesia is applicable for appendectomy in clinic but is still to be improved further in operation.展开更多
