World Journal of Gastroenterology 2011年第13期17卷 1746-1752页

作者： Sen Hu Jin-Wei Che Yi-jun Tian Zhi-Yong Sheng Research Laboratory of Shock and Multiple Organ Dysfunction Burns Institute First Hospital Affiliated to the PLA GeneralHospital Beijing 100048 China

AIM: To investigate the effect of carbachol on gastrointestinal function in a dog model of oral resuscitation for burn shock. METHODS: Twenty Beagle dogs with intubation of the carotid artery, jugular vein and jejunum for 24 h were subjected to 35% total body surface area fullthickness burns, and were divided into three groups: no fluid resuscitation (NR, n = 10), in which animals did not receive fluid by any means in the first 24 h postburn; oral fluid resuscitation (OR, n = 8), in which dogs were gavaged with glucose-electrolyte solution (GES) with volume and rate consistent with the Parkland formula; and oral fluid with carbachol group (OR/CAR, n = 8), in which dogs were gavaged with GES containing carbachol (20 μg/kg), with the same volume and rate as the OR group. Twenty-four hours after burns, all animals were given intravenous fluid replacement, and 72 h after injury, they received nutritional support. Hemodynamicand gastrointestinal parameters were measured serially with animals in conscious and cooperative state. RESULTS: The mean arterial pressure, cardiac output and plasma volume dropped markedly, and gastrointestinal tissue perfusion was reduced obviously after the burn injury in all the three groups. Hemodynamic parameters and gastrointestinal tissue perfusion in the OR and OR/CAR groups were promoted to pre-injury level at 48 and 72 h, respectively, while hemodynamic parameters in the NR group did not return to pre-injury level till 72 h, and gastrointestinal tissue perfusion remained lower than pre-injury level until 120 h post-burn. CO 2 of the gastric mucosa and intestinal mucosa blood flow of OR/CAR groups were 56.4 ± 4.7 mmHg and 157.7 ± 17.7 blood perfusion units (BPU) at 24 h postburn, respectively, which were significantly superior to those in the OR group (65.8 ± 5.8 mmHg and 127.7 ± 11.9 BPU, respectively, all P < 0.05). Gastric emptying and intestinal absorption rates of GES were significantly reduced to the lowest level (52.8% and 23.7% of

Relationship between carbachol Hyperstimulation-Induced Pancreatic Acinar Cellular Injury and Trypsinogen or NF-κB Activation in Rats in vitro

引用

Journal of Huazhong University of Science and Technology(Medical Sciences) 2006年第1期26卷 34-35,58页

作者：郑海蒋春舫张进祥王琳芳方开峰 Department of Emergency Surgery Union Hospital Tonji Medical College Huazhong University of Science and Technology Wuhan 430022 China

The relationship between M3 cholinergic receptor agonist （carbachol） hyperstimulationinduced pancreatic acinar cellular injury and trypsinogen activation or NF-κB activation in rats was studied in vitro. Rat pancreatic acinar ceils were isolated, cultured and treated with carbachol, the active protease inhibitor （pefabloc）, and NF-κB inhibitor （PDTC） in vitro. Intracellular trypsin activity was measured by using a fluorogenic substrate. The cellular injury was evaluated by measuring the leakage of LDH from pancreatic acinar ceils. The results showed that as compared with control group, 10-3 mol/L carbachol induced a significant increase of the intracellular trypsin activity and the leakage of LDH from pancreatic acinar cells. Pretreatment with 2 mmol/L pefabloc could significantly decrease the activity of trypsin and the leakage of LDH from pancreatic acinar cells （P〈0. 01） following the treatment with a high concentration of carbachol （10^-3 mol/L） in vitro. The addition of 10^-2mol/L PDTC didn＇t result in a significant decrease in the activity of trypsin and the leakage of LDH from pancreatic acinar cells treated with a high concentration of carbachol （10^-3 mol/L） in vitro （P〉0. 05）. It was concluded that intracellular trypsinogen activation is likely involved in pancreatic acinar cellular injury induced by carbachol hyperstimulation in vitro. NF-κB activation may not be involved in pancreatic acinar cellular injury induced by carbachol hyperstimulation in vitro.

在早期工作发现小剂量亚硒酸钠 (Sodiumselenite)对离体皮质神经元的致凋亡作用的基础上 ,观察了在亚硒酸钠致凋亡模型中加入M型胆碱能受体激动剂carbachol(Carb)能否阻止凋亡过程和相伴随的有关基因表达的改变。结果显示 :①用不同剂量 (0 .0 0 4 ,0 .0 2 ,0 .1,0 .5,2 .5和 12 .5mmol/L)的Carb和 0 .5μmol/L亚硒酸钠共同处理培养的新生小鼠皮质神经元时 ,用琼脂糖凝胶电泳DNA梯形检测和流式细胞仪亚二倍体峰检测 ,都证明Carb表现出对亚硒酸钠致凋亡作用的剂量依赖性保护效应 ;②用RT PCR技术证明 ,在与Carb共同孵育的实验中 ,不再出现或减弱了亚硒酸钠单独处理时出现的bcl 2基因表达的下调和bax ,p53,c fos以及AChE基因表达的上调。上述结果表明 ,亚硒酸钠对皮质神经元的致凋亡作用和与之相伴随的基因表达的改变 ,可被一定浓度的Carb所阻断 ,提示亚硒酸钠致凋亡作用可能同本室发现的 β 淀粉样蛋白的C末端 5肽片段的致凋亡作用具有类似的途径 ,以类似的基因表达改变为基础 ,并对Carb的抗凋亡机制进行了讨论。

采用记录大鼠伤害性屈肌反射积分肌电图的方法，观察了鞘内注入Ｃａｒｂａｃｈｏｌ（Ｃａｒ，胆硷能Ｍ受体激动剂）及吗啡引起的抗痛作用，并分析了纳洛酮（μ受体阻断剂）、优降糖（ＫＡＴＰ通道阻断剂）及阿托品对上述药物抗痛作用的影响，结果显示：①鞘内注入Ｃａｒ引起剂量依赖性的抗痛作用；②Ｃａｒ的抗痛作用可被鞘内予先注入纳洛酮或优降糖阻断；③鞘内注入吗啡引起的抗痛作用可被优降糖阻断，但不能被阿托品所阻断。这些结果提示：内源性阿片肽和ＫＡＴＰ通道介导了Ｃａｒ或乙酰胆硷引起的脊髓抗痛作用，在此过程Ｍ受体的激活引起内源性阿片肽的释放，后者通过打开ＫＡｒｐ通道实现镇痛。

Munc18/SNARE proteins’ regulation of exocytosis in guinea pig duodenal Brunner’s gland acini

引用

World Journal of Gastroenterology 2008年第15期14卷 2314-2322页

作者： Laura I Cosen-Binker Gerry P Morris Stephen Vanner Herbert Y Gaisano Department of Medicine University of Toronto Toronto Ontario M5S 1A8 Canada Gastrointestinal Diseases Research Unit Queen's University Kingston Ontario KL7 5G2 Canada

AIM: To examine the molecular mechanism of exocytosis in the Brunner’s gland acinar cell. METHODS: We used a submucosal preparation of guinea pig duodenal Brunner’s gland acini to visualize the dilation of the ductal lumen in response to cholinergic stimulus. We correlated this to electron microscopy to determine the extent of exocytosis of the mucin-filled vesicles. We then examined the behavior of SNARE and interacting Munc18 proteins by confocal microscopy. RESULTS: One and 6 μmol/L carbachol evoked a dose- dependent dilation of Brunner’s gland acini lumen, which correlated to the massive exocytosis of mucin. Munc18c and its cognate SNARE proteins Syntaxin-4 and SNAP-23 were localized to the apical plasma membrane, and upon cholinergic stimulation, Munc18c was displaced into the cytosol leaving Syntaxin-4 and SNAP-23 intact. CONCLUSION: Physiologic cholinergic stimulation induces Munc18c displacement from the Brunner’s gland acinar apical plasma membrane, which enables apical membrane Syntaxin-4 and SNAP-23 to form a SNARE complex with mucin-filled vesicle SNARE proteins to affect exocytosis.
