Moclobemide and specific serotonin re-uptake inhibitor combination treatment of resistant anxiety and depressive disorders

This retrospective study was undertaken with the objective of determining how effective and safe moclobemide, a specific and reversible inhibitor of monoamine oxidase-A (RIMA), is when used in combination with specific serotonin re-uptake inhibitors (SSRIs), in a clinical setting. A thorough chart review was done of all patients with affective and anxiety disorders seen at our centre who received combination treatment with moclobemide and an SSRI. Combination moclobemide-SSRI treatment demonstrated good efficacy in treating treatment-resistant patients. The combination treatment was well tolerated with very few drug interactions. Dosages should be started low, titrated slowly and carefully, and patients should be monitored closely.     

The role of intestinal flora on the interactions between nonparenchymal cells and hepatocytes in coculture

Kupffer cells are exposed directly to a number of factors in the portal circulation that can modify or regulate their responses to septic stimuli. The gut represents a potential source of a number of these factors including endotoxin, lymphokines, and prostaglandins. We examined Kupffer cells from germfree rats and germfree rats exposed to endotoxin or bacteria via their GI tracts to determine the importance of the intestinal flora in maintaining or modulating Kupffer cell responses. Kupffer cells from germfree animals were reduced in numbers and failed to respond to LPS in Kupffer cell: hepatocyte coculture. When germfree rats were exposed to bacterial endotoxin or bacteria via the gastrointestinal tract their Kupffer cells increased in numbers to normal and the cells responded to LPS in culture. Intestinal overgrowth with Escherichia coli for 2 days activated the Kupffer cells and significantly increased Kupffer cell sensitivity to LPS. These data suggest that the environment of the gastrointestinal tract is important for normal Kupffer cell responses and that intestinal bacterial overgrowth can modify Kupffer cell responses to septic stimuli.     

秦巴山区野生与栽培猪苓菌核主要成分的测定

采用原子吸收分光光度法、高效液相色谱等方法对秦巴山区野生与栽培猪苓菌核的氨基酸、水分、灰分、粗蛋白、粗脂肪、粗纤维、矿质元素、猪苓多糖等主要成分及含量进行测定.结果表明,野生和栽培猪苓在所测定的17种氨基酸中,7种必需氨基酸占氨基酸总量的质量分数分别为33.8%,23.6%.每100g野生与栽培猪苓菌核中水分质量分别为13.22g,11.94g;灰分质量分别为2.86g,2.61g;粗蛋白质量分别为6.87g,4.91g;粗纤维质量分别为27.62g,26.02g;粗脂肪质量分别为1.87g,1.71g;每100g野生和栽培猪苓质量分别为1.87g,1.71g;猪苓多糖质量分别为0.51g,0.40g.

床边纤维支气管镜检查在可疑院内获得性肺炎诊断中的意义

目的评价床边纤维支气管镜检查在可疑院内获得性肺炎诊断中的意义。方法对25例可疑院内获得性肺炎患者进行床边纤维支气管镜检查，同时进行痰标本和支气管肺泡灌洗液标本涂片细菌检测和培养。结果1例为肺出血，2例肺不张，1例肺水肿；21例为院内获得性肺炎，其中14例(72．7％)细菌培养阳性，革兰阴性杆菌占57．1％(12／21)，以铜绿假单胞菌、不动杆菌属、嗜麦芽假单胞菌、肺炎克雷伯菌最常见，革兰阳性球菌2例(9．5％)，主要是耐甲氧西林金黄色葡萄球菌。痰涂片和支气管肺泡灌洗液涂片阳性者分别为3例和10例。支气管肺泡灌洗液细菌涂片阳性率和细菌培养阳性率均高于痰标本(P=0．02和P=0．005)。结论床边纤维支气管镜检查有助除外疑似院内获得性肺炎的非感染性疾病。支气管肺泡灌洗液标本病原学检测优于痰标本。
