人下鼻甲微血管内皮细胞的体外培养及鉴定

目的:研究人下鼻甲微血管内皮细胞的体外培养方法,为鼻腔、鼻窦相关疾病的研究提供实验基础。方法:采用手术中获得的人下鼻甲边缘黏膜及黏膜下组织,机械分离和酶解消化微血管内皮细胞,在体外条件下进行培养。分别行细胞形态学观察、细胞生长曲线的测定和培养细胞免疫荧光鉴定。结果:体外培养条件下得到人下鼻甲微血管内皮细胞,经细胞形态学观察、细胞生长曲线测定及免疫荧光鉴定证实为血管内皮细胞。结论:本研究获得的体外培养人下鼻甲微血管内皮细胞,可为鼻腔过敏性疾病和炎症性疾病的微血管病理改变及药物对鼻腔下鼻甲微血管功能影响等研究提供实验基础。     

改良安瓿折断器的临床应用

在临床护理工作中,因折安瓿而割伤手的事件时有发生,尤其是新上岗的护士更易发生,其不仅给护士造成了痛苦,也增加了护士院内感染的机会.根据实际工作体会,我们制作了一种改良安瓿折断器并经临床应用取得了良好的效果.现介绍如下.     

冯氏捏积疗法治疗小儿缺铁性贫血(脾胃虚弱型)201例

目的:观察冯氏捏积疗法治疗小儿缺铁性贫血(脾胃虚弱型)的临床疗效。方法:将387例IDA患者随机分为两组,治疗组201例,对照组186例。治疗组采用冯氏捏积手法,对照组口服富马酸亚铁咀嚼片。结果:治疗组总有效率77.61%,对照组总有效率74.73%。两组比较有显著性差异(P<0.05)。结论:冯氏捏积疗法治疗小儿缺铁性贫血(脾胃虚弱型)疗效优于对照组。     

小儿消化性溃疡72例临床分析

小儿消化性溃疡症状不典型,临床诊断较困难,易误诊,现将2001年-2006年本院经X线胃肠钡餐证实的72例小儿消化性溃疡综合分析如下。     

朝鲜淫羊藿中的黄酮类化合物

朝鲜淫羊藿和淫羊藿属的有关种是重要的中草药,它们的地上部分被用作为刺激荷尔蒙分泌的滋补剂,治疗阳痿和健忘症,而其地下部分被用来治疗气喘发作和月经不调。作者以前曾报道过从朝鲜淫羊藿中分到n-链烷、甾醇、甾醇甙和黄酮,本文报道从其地下部分分到2种新的含异戊二烯基的黄酮醇甙(1)、(4)和Epimdeoside A(2),淫羊藿素(3),Ikarisoside A(5)。干燥的生药用甲醇回流提取3h(4次),提取液减压浓缩后的残渣,悬浮于蒸馏水中,     

奥曲肽联合血塞通治疗急性胰腺炎疗效观察

目的研究奥曲肽联合血塞通与常规治疗急性胰腺炎的疗效.方法80例急性胰腺炎患者随机分为两组,对照组44例为常规治疗,治疗组36例同时用奥曲肽0.1 mg加入5%葡萄糖溶液250 ml静脉滴注,8小时1次,血塞通400 mg加入5%葡萄糖溶液250ml静脉滴注,1日1次,均至腹痛消失,血、尿淀粉酶恢复正常.结果在观察腹痛、压痛与反跳痛、血、尿淀粉酶、体温方面,治疗组显效率、总有效率明显优于对照组(P＜0.01).结论奥曲肽联合血塞通治疗急性胰腺炎在缩短疗程、稳定病情方面更为显著,且无不良反应,值得推广.     

欧可芬在白内障手术前后的临床疗效观察

本文通过对８０例白内障病人术前术后滴用欧可芬眼液作观察及与６０例对照组病人术前术后滴用生理盐水作比较，发现有显著的差异性。欧可芬眼液在白内障手术中有明显的保持瞳孔扩张，并在术后有明显的抗炎作用。     

HEARING SHIFT AND INNER EAR PATHOLOGY OF GUINEA PIGS EXPOSED TO OCTAVE BANDS OF NOICE CENTERED AT 63 Hz AND 4kHz

Twenty-four guinea pigs with normal Preyer's reflex were exposed to the octave bands of noise centered at 63 Hz and 4 kHz, 110 dB SPL. The duration of exposure was 4 and 8 hours respectively. The permanent shift of the guinea pigs at the above two frequencies was at 4-8 kHz. As the duration of exposure were 4 hours, the threshold shift at 63 Hz was smaller than that at 4 kHz. But as the duration of exposure was 8 hours, the threshold shift at 63 Hz and 4 kHz was almost the same. No morphological change of the inner ear was observed in the guinea pigs exposed for 4 hours at the octave bands of noise centered at 63 Hz and 4 kHz, but ultrastrnetural abnormalities were noted. After the animals were exposed for 8 hours, morphological, ultrastructural changes in the inner ear were observed. The main pathologic changes were seen at the second turn of the cochlea. These changes in hearing physiology and pathology suggest that a high intensive low frequency noise can result in high frequency hearing loss and that
