实用缺锌动物模型的饲料研究

研究实用缺锌饲料是建立缺锌动物模型的重要条件。以蛋清为缺锌饲料的蛋白质原料,经EDTA络合后,锌含量可低于0.8mg/kg,与经EDTA处理后的大豆粉、酪蛋白含锌量比较。结果显示,经处理后的蛋清含锌量明显低于大豆粉、酪蛋白中的锌含量。使用处理后蛋清配制的缺锌饲料锌的含量为1.07～2.16mg/kg。本法制成的饲料价格便宜,含锌量低,是一种实用的缺锌动物模型的半合成饲料。     

双极射频控温热凝器体外量效关系的实验研究

目的 研究双极射频控温器时间、预设温度、间距对两电极热效应的影响。 方法 选择新鲜鸡蛋清,按随机数字表法分为不同间距组、温度组和时间组,固定2个射频电极保持针身垂直置入方盘中央蛋清内,用预设温度（50～90℃）、射频时间（60s、120s）、电极间距（0.25、0.50、1.00和2.00cm）进行干预,通过游标卡尺、秒表、阻抗及温度检测,观测两电极真实温度、出现纺锤形连接的间距、不同温度下蛋清变性的时间跨度、蛋清阻抗变化、蛋清变性的最低温度、不同时间蛋清变性量（体积）和不同温度下蛋清变性阻抗的变化。 结果 ①当电极间距固定保持2.00cm,预设温度设定在63℃,主电极真实温度为63.7℃,次电极真实温度52.6℃,次极温度与预设温度、主极温度的分布差异有统计学意义（P<0.05）,电极间距在0.25、0.50、1.00cm时,次极温度-预设温度和主极温度-次极温度差异有统计学意义（P<0.01）;②在间距为0.25cm,56℃时开始出现蛋清变性,在0.25cm、0.50cm间距,温度70℃以上两电极之间出现纺锤形连接,在1.00cm和2.00cm间距时同样温度未出现该现象;③在间距为0.25cm时,预设温度75℃,单次射频60s、单次射频120s及2个单次射频60s后蛋清体积分别为(90.21±0.64)mm3、(95.08±0.53)mm3、(92.88±0.74)mm3,蛋清的变性体积差异均有统计学意义(P<0.01);④单次射频60s蛋清射频前、后电阻差异无统计学意义（P=0.11）,单次射频120s蛋清射频前和射频后电阻分别为（128.41±8.04）Ω和（121.29±8.04）Ω,差异有统计学意义（P=0.02）。 结论 双极射频能使蛋清组织变性,温度越高、时间越长、电极间距越小引起的变性效率越高。     

蛋清蜂蜜合剂治疗烧烫伤感染24例

烧烫伤属外科常见病,是严重危害身体健康及生命的外伤性疾病,如不及时治愈,造成创面感染、或过早使用收涩药造成创面干涸结痂,痂下再次蓄脓,则会使疮面愈合速度变得更慢,甚或感染进一步加深,给患者带来极大痛苦,或造成不良后果.     

声音沙哑

取鸡蛋两枚，红茶（乌龙茶或其他有涩味的茶亦可）、冰糖各少许。将鸡蛋去掉壳及蛋黄，取出蛋清，放在碗中备用。将红茶放入杯中，用温度为9000的热水冲泡片刻，去渣取汁。将此茶汁倒入装有蛋清的碗中，并快速地进行搅拌，使蛋清变成蛋花，再调入冰糖，等冰糖溶化、温度适宜后慢慢服下，每天服2次（由感冒引起的咽喉发炎、肿痛、声音沙哑等症状，不适合使用此方进行治疗。有脾胃虚寒症状者不可多饮此茶）。     

蛋清溶菌酶部分酶学性质及酶活性的影响因素研究

目的探讨将蛋清溶菌酶制成液体制剂的可行性。方法通过改变不同影响因素测定蛋清溶菌酶的活性,观察几种常用辅料对蛋清溶菌酶活性的影响。结果酶活性在pH 6.0~6.5最强,且在pH 5~7范围内较稳定;在25~65℃范围内随着作用温度的升高酶的活性增强,但温度太高则变性失活;Na+、K+对其活性有轻微激活作用,Mn2+、Mg2+对溶菌酶活性无明显影响,Co2+、Ca2+、Cu2+、Fe2+、Zn2+使溶菌酶的活性下降;吐温20、吐温80、甘油溶液对酶活有抑制作用;EDTA-2Na在0.000 5%~0.300 0%浓度范围内对溶菌酶活性具有激活作用,浓度继续增加反而有抑制活性作用。结论初步试验结果表明溶菌酶可以制成合适的液体制剂。     

Effects of phosphodiesterase 4 inhibitor on cough response in guinea pigs sensitized and challenged with ovalbumin

Background There is currently considerable interest in the potential value of selective inhibitors of cyclic nucleotide phosphodiesterase 4 in the treatment of asthma. However, whether they influence eosinophilic airway inflammation-associated cough remains unclear. The objective of this study was to investigate the effects of selective phosphodiesterase 4 inhibitor SB207499 on cough response and airway inflammation in guinea pigs sensitized and challenged with ovalbumin. Methods Forty sensitized guinea pigs were randomly divided into four groups: control (n=10), challenge (n=10), SB207499 (n=10) and aminophylline (n=10), then challenged with aerosol of 1% ovalbumin or saline. Two hours later, animals were intraperitoneally injected with either saline, 25 mg/kg of SB207499 or aminophylline. At the 24th hour, the injection was repeated with 2.5 mg/kg and 25 mg/kg SB207499 or aminophylline, then cough response to inhaled capsaicin and airway responsiveness to methacholine inducing a 150% of the peak airway pressure to the baseline (PC150) was measured. Finally, total cell number and differentials in bronchoalveolar lavage fluid were analysed. Results The cough frequency per 3 minutes and PC150 in the challenge group were (22±4) times/3 minutes and (198±54) μg/ml, which were significantly different from (6±2) times/3 minutes and (691±81) μg/ml in the control group (P&lt;0.05, respectively). The injection of 25 mg/kg SB207499 significantly inhibited the increased cough response and airway hyperresponsiveness, the cough frequency and PC150 in guinea pigs were (13±2) times/3 minutes and (680±81) μg/ml (P&lt;0.05), which differed significantly from (18±2) times/3 minutes and (400±86) μg/ml after the administration of the same dose of aminophylline (P&lt;0.05). The inhibition of SB207499 on cough response was dose-dependent. Similarly, SB207499 decreased the total cell number and percentage of eosinophils in bronchoalveolar lavage fluid to (2.1±0.5)×10（6）/ml and (20±5)% respectively, which were significantly different from (3.2±0.5)×10（6）/ml and (29±5)% in the aminophylline group (P&lt;0.05, respectively) or (4.2±0.7)×10（6）/ml and (35±4)% in the challenge group (P&lt;0.05, respectively). Conclusion Phosphodiesterase 4 inhibitor may be more useful than aminophylline for cough associated with eosinophilic airway inflammation via inhibiting airway inflammation and airway hyperresponsiveness.
