In this experiment, we found the water of wheat leaves increase 0.6%~3.06 % for wet weigh and 17%~99.73 % for dry weigh,The oppositely containing the water increase 0.24%~3.42 %, The water saturation decrease 0.24%~3.39 %.The resulte of the leaves of corn is similar with wheat. it indicates that treat with extracts of peganum harmala could enhance the drought resist ability of wheat and corn.

试验结果表明，凡种子经过处理后，小麦叶片水分占鲜重的量增加了0.6%~3.06 %，占干重的量增加了17%~99.73 %，相对含水量增加了0.24%~3.42 %，而水分饱和度降低了0.24%~3.39 %；玉米处理结果与其一致，表明浸种处理具有增强作物抗旱性的生理效应。

Results The average operation time was 23.5min. The average hospital stay was 3.5d. The correction of the prolapsed hemorrhoids was satisfied in 93.5% patients. Intraoperative hemorrhea occurred in two cases because the large range rectum mucosa was uncompletely stapled or cut. Urine retention occurred in 184 cases (31.9%), anal pain in 357 cases (62%) and a second operation were performed in 3 cases because of postoperative hemorrhea. A total of 484 cases were followedup for 14 years. The postoperative satisfaction rate of symptom improvement was 94 .3%. Four cases underwent thrombosed external hemorrhoid resection. Other patients had no recurrence, no anal stenosis and no fecal incontinence.
