Objective:To study the relationship between serum pepsinogen levels and the recurrence of gastric cancer after total gastrectomy.

目的：研究胃癌患者全胃切除手术后血清胃蛋白酶原Ⅰ（PepsinogenPGⅠ）、胃蛋白酶原Ⅱ含量的变化与胃癌复发的关系，探讨血清PGⅠ、PGⅡ作为胃癌复发标志物的可能性。

Serum pepsinogenⅠ and pepsinogen Ⅱ levels were measured by radioimmunoassay in 190 healthy controls, 103 patients with gastric cancer before operation, 33 patients after partial gastrectomy, 18 patients after total gastrectomy, and 23 return visit patients after total gastrectomy.

运用放射免疫分析方法测定了190例正常人，103例胃癌手术前病人，33例胃部分切除病人，18例全胃切除病人，23例全胃切除后随访病人的血清PGⅠ、PGⅡ的含量，并进行统计学分析。

Methods Enzyme-linked immunosorbent assay was used to measure the serum concentrations of pepsinogen Ⅰand Ⅱin patients with erosive gastritis, atrophic gastritis, bile reflex gastritis and gastric cancer.

方法应用酶联免疫吸附测定法测定糜烂性胃炎、萎缩性胃炎、胆汁反流性胃炎和胃癌患者血清胃蛋白酶原亚群的含量及PGⅠ/PGⅡ比值的变化，并与正常对照比较。

The effects of QDPTP on cerebral blood flow and artery blood pressure in anesthetized rats The regional cerebral blood flow in cerebral pia mater was examined by Laser Doppler Flowmeter and the artery blood pressure (including mean systolic pressure, mean diastolic pressure and mean blood pressure) were monitored by the electrophysiological polygraph before and after drug administration.

结果表明：模型组脑组织及血清IL1-β含量分别为1006.4±247.1 pg/ml和370.8±76.6 pg/ml，与之相比，QDPTP中剂量(550.7±99.8，268±64.6)组中脑组织及血清中IL1-β的含量显著降低(P.01)，川芎嗪脑也明显减少组织IL1-β的含量(627.8±144.7，P.05)。 QDPTP对麻醉大鼠局部脑血流量和动脉血压的影响采用激光多普勒血流仪测量大鼠软脑膜局部的血灌注量，其被视为局部的脑血流量。

The PCR products were detected by both agarose gel electrophoresis and capillary electrophoresis in order to compare their sensitivity. Results Capillary electrophoresis detected the 1/600 of the PCR product from 20 picogram of male DNA, as amount of DNA in 3-4 cells.

结果 毛细管电泳可检测到20 pg男性模板DNA（相当于3-4个细胞中的DNA含量）PCR扩增产物总量的1/600，琼脂糖凝胶电泳可检测到74 pg男性模板DNA（相当于13个细胞中的DNA含量）PCR扩增产物总量的1/3。

The formation of silique dehsicence susceptibility was investigated in terms of water content, synthetic rate of ethylene, enzyme activity of exo polygalacturonase and end cellulase , cell alteration in dehiscence zone in silique and silique dehiscence susceptibility during silique development.

从油菜角果发育过程中角果含水量、乙烯合成速率、外切 PG 酶和内切纤维素酶活性，以及角果裂区切片观察等方面研究了角果开裂敏感性形成的原因⒚花后50d 的角果果柄端壳状果瓣和线状果瓣间的裂区薄壁细胞膨大，在高倍光学显微镜下可见胞间空隙开始形成⒚此前6d 内乙烯合成速率迅速上升并出现第二次合成高峰，与之同步发生外切 PG酶和内切纤维素酶活性急剧上升，而乙烯合成第二高峰出现于角果含水量低于80％以下⒚由此看来，角果失水引起乙烯合成第二高峰出现，从而导致水解酶活性上升，最终导致果瓣裂区薄壁细胞膨大，分离和胞间空隙形成及角果开裂敏感性产生

VEGF,Dexamethasone and VEGF plus dexamethasone groups increase signfinicantly phosphatidylcholine and sphingomyelin than control group.

VEGF和联合应用组尚可增加PG含量，而地塞米松对PG的合成无明显作用。

Intraventricular infusion of 1.6 and 6.4 microM veratridine did not alter MAC. Rats given 25 microM died.

脑室注入1.6和6.4 pg ／ ml 的浓度不改变 MAC 值，给与大鼠25 pg ／ ml 则大鼠死亡。
