In the experiment of contraction of guinea pig gestric smooth muscle, it was found that pD_2 of acetylcholine for longitudinal and circular smooth muscles from guinea pig gastric fundus and body were 6.5 and 4.0 respectively. ThepA_2 values of atropine for these smooth muscles were approximately 10 and 8.5 respectively. This suggests that there were two kinds of muscarinic receptars of different affinities in the stomach and these receptors played a role in contractile function in longitudinal and circular smooth...

In the experiment of contraction of guinea pig gestric smooth muscle, it was found that pD_2 of acetylcholine for longitudinal and circular smooth muscles from guinea pig gastric fundus and body were 6.5 and 4.0 respectively. ThepA_2 values of atropine for these smooth muscles were approximately 10 and 8.5 respectively. This suggests that there were two kinds of muscarinic receptars of different affinities in the stomach and these receptors played a role in contractile function in longitudinal and circular smooth muscles. Specific [~3H]-QNB binding tohomogenates of gastric smooth muscles were also studied by using the method described by Yamamura et al. It was also found that high and low affinity bindings in the homogenates of gastric smooth muscles. The KD values of various homogenates of high and low affinity bindings were 1.8 and 18 nmc/L respectively. Since protein modulators with various functions showed different effects of the bindings of two components to labeled ligand, it is therefore concluded that the two components were the binding sites with different affinities.

从豚鼠胃平滑肌收缩实验测得,胃底、体部纵、环肌的乙酰胆碱pD_2约为6.5和4.0,阿托品的pA_2约为10和8.5。实验结果提示胃平滑肌上存在高、低两种不同亲和力的毒蕈碱受体,分别与胃底、体部的纵、环肌收缩有关。又用Yamamura法对豚鼠胃平滑肌组织中的毒蕈碱受体进行了检定,测得解离常数KD值约为1.8和18 nm的两种组分。由于作用不同的蛋白质修饰剂,对这两种组分与标记配体结合的影响不同,故认为它们是亲和力不同的两种特异结合部位。

With functional experiments in vitro, we observed PD_2 & PA_2 values of atropine & Ach, for longitudinal and circular smooth muscles in gastric fundus, body & antrum of guinea-pig. PD_2 % PA_2 values of longitudinal muscles were significantly different from those of circular muscles in the body & fundus, but similar in the antrum. The maximum contraction of longitudinal &. circular muscles in antrum was less than that in other regiors. The result indicated that two kinds of muscarine receptors with low & high...

With functional experiments in vitro, we observed PD_2 & PA_2 values of atropine & Ach, for longitudinal and circular smooth muscles in gastric fundus, body & antrum of guinea-pig. PD_2 % PA_2 values of longitudinal muscles were significantly different from those of circular muscles in the body & fundus, but similar in the antrum. The maximum contraction of longitudinal &. circular muscles in antrum was less than that in other regiors. The result indicated that two kinds of muscarine receptors with low & high affinities might exist in the body & fundus of the stomach, while in the antrum there mainly were muscarine receptors with low affinity.

采用离体功能实验,测定豚鼠胃底、体、窦部纵、环平滑肌由乙酰胆碱和阿托品引起的PD_2及PA_2。胃底、体部纵、环肌间的PD_2和PA_2差异非常显著,而窦部数值相近。结果提示:胃底、体部纵、环肌上可能存在高、低两种不同亲和性的毒草碱受体,胃窦部则以低亲和性毒蕈碱受体为主。

Objective To investigate the diagnostic and therapeutic method of gastric stromal tumor(GST). Method 40 cases of GST were retrospectively reviewed with regard to clinical manifestation, diagnosis and treatment. Result All cases major manifested as upper abdominal discomfort, tumor were found by gastroscopy, barium meal, computed tomography, and B ultrasonography which located at cardia, gastric fundus and body in 29 cases and gastric antrum in 11 cases. All cases underwent resection, of which wedge resection...

Objective To investigate the diagnostic and therapeutic method of gastric stromal tumor(GST). Method 40 cases of GST were retrospectively reviewed with regard to clinical manifestation, diagnosis and treatment. Result All cases major manifested as upper abdominal discomfort, tumor were found by gastroscopy, barium meal, computed tomography, and B ultrasonography which located at cardia, gastric fundus and body in 29 cases and gastric antrum in 11 cases. All cases underwent resection, of which wedge resection in 14 cases (35.0%), distal subtotal gastrectomy in 11 cases (27.5%), proximal gastrectomy in 14 cases (35.0%), total gastrectomy combined with pancreatic tail resection and splenectomy in 1 case (2.5%). All cases were followed up with average duration of 3.5 years, showed 7 cases of recurrence which underwent subsequent resection, 4 death occurred which were the malignant cases. Conclusion Surgical approach remains the major treatment for GIST, the operation should be designed according to tumor location, tumor size and pathological findings, the surgical margin should be kept a distance of least 3 cm from tumor, no routine lymphatic clearance be requested whereas en-bloc resection should be ensured.

目的探讨胃间质瘤的诊治方法。方法回顾性分析40例胃间质瘤的临床表现、诊断和外科治疗。结果40例中最主要的临床症状为上腹部胀痛不适,经胃镜、胃肠钡透、CT及B超等检查发现,29例肿瘤位于贲门及胃底体部,11例位于胃窦部。40例均经手术切除,切除率为100%,14例(35.0%)行肿瘤单纯切除,11例(27.5%)行远端胃大部切除术,14例(35.0%)行胃近端切除,1例(2.5%)行全胃切除及胰尾和脾切除术。本组均获随访,平均3.5年,7例复发(17.5%),再次行肿瘤单纯切除术或含大网膜的肿瘤切除;4例死亡(10%),均为恶性患者。结论胃间质瘤治疗以手术为主,根据肿瘤部位、大小及病理结果选择不同术式,切缘至少距肿瘤3cm以上,不需常规行淋巴结清扫,术中保证肿瘤的完整性十分重要。
