燕麦纤维和燕麦麸降脂作用的比较

健康ＳＤ断乳大鼠经高脂膳食诱导制成高脂血症模型，观察燕麦麸和燕麦纤维对大鼠血脂、脂蛋白及脂质过氧化的影响。结果表明：２０％燕麦麸、５％和１０％燕麦纤维能够显著降低高脂大鼠血ＴＣ、ＬＤＬ－Ｃ及ＬＰＯ水平，提高血中ＨＤＬ－Ｃ及ＬＰＯ水平，同时还具有清除血中ＴＧ的作用，对ＡＰＯ－ＡＩ和ＡＰＯ－Ｂ也产生有益的影响．提示：燕麦麸具有一定的降脂作用，而燕麦纤维为燕麦降脂的主要有效成分。     

血管紧张素(1-7)和依那普利拉对烧伤血清离体灌注大鼠心脏功能的影响

Objective To investigate effects of angiotcnsin ( 1-7 ) [ Ang( 1-7 ) ] and enalaprilat on function of isolated rat heart perfused by burn serum. Methods Eighty SD rats were used to prepare burn serum. Hearts of another 24 SD rats were isolated to reproduce Langendorff perfusion model. The rat hearts were divided into different groups with different perfusion fluids as K-H buffer group, K-H buffer containing 20% burn serum group ( burn serum group) , K-H buffer containing 20% burn serum and 2 μg/mL enala-prilat group (enalaprilat group), and K-H buffer containing 20% burn serum and 1 nmol/mL Ang(1-7) group [ Ang(1-7) group]. The rat hearts were perfused for 30 mins with each of above-mentioned fluids in different groups. Then left ventrieular systolic pressure (LVSP) , left ventricular end diastolic pressure ( LV-EDP) , ± dp/dt max, coronary flow(CF) , level of creatine kinase (CK) and lactate dehydrogenase (LDH) in respective coronary effluent were determined. Results Compared with LVSP ( 11.2 ± 1.0 kPa, 1 kPa = 7.5 mm Hg), +dp/dt max (642±53 kPa/s), -dp/dt max (380±61 kPa/s) and CF level in K-H buffer group, CF, LVSP(5.9±0.8, 8.0±1.1, 8.9±1.3 kPa, respectively), +dp/dt max(275±37, 454±48, 479±63 kPa/s, respectively), - dp/dt max ( 135±35, 219±47, 277±58 kPa/s, respectively ) of burn serum group, those levels in Ang(1-7) group, and enalaprilat group were decreased obviously(P<0.05 or P <0.01 ), but LVEDP, level of CK and LDH in coronary effluent were increased. Compared with those parameters in burn serum group, CF, LVSP, ±dp/dt max of Ang(1-7) group and enalaprilat group were increased obviously(P<0.05 or P<0.01), and LVEDP, level of CK and LDH in coronary effluent were decreased obviously(P<0.01). Conclusions Ang(1-7) and enalaprilat can effectively improve left ventricular function of isolated rat heart perfused by burn serum and mitigate myocardial injury.

皮蛋中铅残留量的调查研究

皮蛋是我国发明的具有独特风味的传统食品。为保证皮蛋的外观质量、风味、色泽等,制做时配料中需加入一定量的一氧化铅(PbO),因而使皮蛋有铅的残留。铅是对人体有害的重金属,能在体内蓄积甚至引起慢性中毒。为了解市售皮蛋铅残留水平及皮蛋中铅残留量与配料中一氧化铅用量及腌制时间的关系,我们对市售皮蛋及实验室自制皮蛋进行了铅含量测定。同时进行感官检查,观察一氧化铅的作用,以     

老年肺结核40例临床分析

分析了1990～1994年间住院的40例老年肺结核(OLT)的临术特点,并与56例青年肺结核(YLT)比较。发现OLT入院时常误诊为其它呼吸系疾病;痰抗酸菌阳性率明显低于YLT;聚合酶链反应(PCR)检测血结核菌DNA(TB—DNA)结果及结核菌纯蛋白衍生物(PPD)皮试均阳性者明显低于YLT;经纤支镜(FB)及经皮肺穿活检阳性率与YLT无明显差异;病灶空洞形成率明显高于YLT;病灶累及两叶以上者明显高于YLT;有合并症者明显高于YLT;并发症亦明显高于YLT。笔者建议对反复咳嗽、咯痰的老年患者警惕OLT可能。
