| 摘 要： | 研究了低温冰箱冷冻保存时间对人体甲状腺组织、子宫肌瘤组织的拉曼光谱的影响。组织用磷酸缓冲生理液浸泡 ,于 - 4℃保存 (未冻 ) 1 0 h,测试拉曼光谱 ;测后将组织样品浸入磷酸缓冲生理液 ,置于低温冰箱 - 30℃保存。分别于冷冻几天、十几天和六十天后 ,取出解冻测试拉曼光谱。结果表明 ,冷冻保存 1 0天内对组织的拉曼光谱没有明显的影响。该结果对拉曼光谱研究人体组织具有指导意义

| Abstract: | The effects of frozen time on the Raman spectra of human thyroid and uterine muscle benign tumor tissues at 514.5nm excitation were studied.The samples were kept in phosphate buffered saline,without freezing,and tested in 10h after the surgical resection.The same specimen was then frozen in cryogenic refrigerator,and examined at intervals from several days to 60 days.The results show that the Raman spectra of human tissues were not observed obvious changes by storage in cryogenic refrigerator within 10 days.These studies could be utilized to guide future experimental design during Raman spectroscopy of biological tissues. |
