1988年6～8月,我科在上海消化研究所协作指导下,在电子胃镜直视下测定胃粘膜电位(Gastric-mucosal Patentia1 Difference,简称PD)共10例。其中十二指肠球部溃疡活动期5例,萎缩性胃炎5例。用美国Welch-Allyn公司电子胃镜及Olympus XQ-10型纤维胃镜,按常规行内窥镜检查。胃粘膜测定电极,由上海第二医科大学自行设计制造。将测定电极经内镜活检孔道插入胃内,测定所需的胃粘膜电位。测定电极为Ag-/rgcl电极(参考电极相同放,置于上肢前臂内侧皮肤上)用计算机直接测定读出计数。PD单位为my。结果见附表。
From June to August 1988, under the guidance of the Shanghai Institute of Digestive Research, our department measured 10 cases of Gastric-mucosal Patentia Difference (PD) under direct observation by electronic gastroscope. There were 5 cases of active duodenal ulcer and 5 cases of atrophic gastritis. Endoscopy was performed routinely using a Welch-Allyn Corporation electronic gastroscope and an Olympus XQ-10 type gastroscope. Gastric mucosa measuring electrodes were designed and manufactured by Shanghai Second Medical University. The measuring electrode was inserted into the stomach through the endoscopic biopsy hole and the required gastric mucosal potential was measured. The measurement electrode was an Ag-/rgcl electrode (the same reference electrode was placed on the inner skin of the forearm of the upper limb) and the readout count was measured directly by a computer. The PD unit is my. The results are given in the attached table.
