高效液相色谱法检测玉米浆中的氨基酸

玉米是生产青霉素的主要原料,玉米种氨基酸含量的分析是不可或缺的步骤,对于控制发酵参数有重要意义。传统的氨基酸分析多采用化学比色法或电泳法,耗时较长,步骤繁琐,影响因素多且灵敏度较差。作者在查阅文献的基础上,利用现有高效液相色谱仪,建立了玉米浆中氨基酸的分析方法,经实际应用,证明该方法简单、灵敏,影响因素少,分析条件易于控制、掌握,是适合分析氨基酸的较好方法。现将结果报告如下。1材料与方法1.1仪器日本岛津产高效液相色谱仪(型号SPD—10A.VP),超声波清洗器(型号LAB—LINEAQUAWAVEULTRASONICCLEANERS.9314-…     

不同液体术前急性高容量血液稀释对深静脉血栓病人血液流变学的影响

Objective To investigate the effects of acute hypervolemic hemodilution (AHH) with different fluids on blood rheology in patients with deep vein (femoral and iliac) thrombosis. Methods Thirty ASA I or II patients aged 40-64 yr who had developed deep vein thrombosis in 48 h and were scheduled for embolectomy were randomly divided into 3 groups ( n = 10 each) ; group I normal saline (NS) ; group II 6 % HES 200/0.5 ( HES) ; group IE gelofusine (GEL). AHH was performed with normal saline, 6% HES or gelofusine infusion at 20 ml·kg-1 ·h-1 for 40 min. MAP, HR and SpO2 were monitored. Blood loss, volume of blood transfusion and fluid infused and urine output during operation were recorded. Anesthesia was induced with fentanyl 3-5 fig/kg, etomidate 0.15-0.30 mg/kg, propofol 1-2 mg/kg and succinylcholine 1-2 mg/kg and maintained with 2% isoflurane and propofol infusion at 5-8 mg·kg-1·h-1 and intermittent iv boluses of vecuronium. The patients were mechanically ventilated (VT 8 ml/kg, RR 12 bpm). PaO2 and PaCO2 were maintained within normal range. Venous blood samples were obtained before and after AHH for measurement of hematocrit (Hct), whole blood viscocity (WBV) at low or high shear rates, plasma viscosity, RBC aggregation and RBC deformation. RBC aggregation index and RBC deformation index were calculated. Results MAP and HR were stable in all patients. The amount of blood transfusion and fluid infused was significantly less in group HES and GEL than in group NS. The WBV at low or high shear rates in group HES and GEL, Hct in all 3 groups and RBC aggregation index in group HES were significantly decreased after AHH, but the RBC deformation index was significantly increased in group HES. Conclusion Colloid is better than crystalloid and HES is better than gelofusine in improving intraoperative hypercoagulability and sluggish blood flow.

急性胰腺炎的诊治进展

急性胰腺炎（acute pancreatifis，AP）是指多种病因引起的胰酶激活，继以胰腺局部炎症反应为主要特征，伴或不伴有其他器官功能改变的疾病。临床上，大多数患者的病程呈自限性；20％～30％患者临床经过凶险。总体死亡率为5％～10％。AP临床上表现为急性、持续性腹痛（偶无腹痛），血清淀粉酶活性增高大于或等于正常值上限3倍，影像学提示胰腺有（无）形态改变，排除其他疾病者。可有（无）其他器官功能障碍。少数病例血清淀粉酶活性正常或轻度增高。     

冷饭热后难消化

剩饭重热后再吃,或将剩饭炒了再吃,不少人以为这样既卫生又节约。其实,剩饭重热后再吃难以消化,久而久之可能引起胃病。 让我们先来看看米饭中所含的主要成分淀粉是怎样在体内消化吸收的吧。首先,口腔内的唾液淀粉酶将淀粉水解成糊精及麦芽糖。其次,是在小肠内由胰腺分泌的胰淀粉酶和双糖酶继     

食盐对普通玉米杂交种淀粉糊化性质的影响

采用快速粘度分析仪（RVA）研究了食盐对18种普通玉米杂交种淀粉糊化性质的影响。结果表明：食盐显著降低了所有普通玉米杂交种淀粉的峰值、破损值和回生值;提高了谷值、终粘度、出峰时间和成糊温度。但对不同的普通玉米杂交种淀粉的糊化性质的影响程度有显著差别。随着食盐溶液质量分数的增加,普通玉米杂交种淀粉的谷值、终粘度、出峰时间和成糊温度也逐渐增加,破损值和回生值则显著降低,峰值受食盐溶液质量分数的影响很小。     

口服吸附剂治疗慢性肾功能衰竭研究进展

口服吸附剂是治疗慢性肾功能衰竭的有效手段之一，对于延迟肾衰发展进程，减少尿毒症的发生和血液透析的次数，尤其对于慢性肾功能衰竭早期预防和治疗是非常重要的。口服吸附剂疗法由于安全有效，价格低廉，便于服用，近年来备受关注，已逐渐成为治疗慢性肾衰竭的重要手段。目前，“吸附疗法”己被列为尿毒症的现代治疗方法之一。     

胸水淀粉酶测定对癌性胸水的诊断价值(附40例分析)

本文报告了40例胸腔积液患者的胸水及血清淀粉酶的测定结果,发现恶性胸水淀粉酶升高者达66.7%,其中腺癌占33.3%。提示在难以取得病理组织时,胸水淀粉酶测定对胸水定性及胸内肿瘤早期诊断有一定价值。
