绒癌化疗和实施手术时期的选择

绒癌化疗和实施手术时期的选择友田丰，他与其他实性癌肿相比，绒癌的疗效较理想。近年，非转移性绒癌病例的缓解率几乎可达１００％，即使有转移灶者，其缓解率亦接近８０％。这种疗效的提高是近年妇产科医生采用以化疗为中心的综合方法所取得的积极成果。对绒癌的治疗有...     

神经母细胞瘤筛查方法—点片法、双向纸层析法

神经母细胞瘤(Neuroblastoma,NB)是儿童时期常见的恶性肿瘤,常因缺乏明显的临床症状而不能及时确诊。作者应用点片法、双向纸层析法,对患儿尿内的儿茶酚胺代谢产物——香草扁桃酸(VMA)、高香草酸(HVA)、香草乳酸(VLA)进行测定,为NB筛查、诊断提供生化依据。1 资料与方法     

ISCHEMIC PAPILLOPATHY AND CONTRACEPTIVES

In January and again in April 1985, a 30-year old woman received 150 mg injections of Depo-Provera for contraception. 3 days after the 2nd injection, she experienced blurred vision in both eyes and was diagnosed as having bilateral papilledema. Her vision improved after treatment with vitamin B1 and other drugs. But optic atrophy of the right eye and papilledema of the left eye remained. In July 1985, after an injection with Depo-Provera, her vision again worsened. The woman received no more Depo-Provera after this time. In early 1987, she was referred to Beijing's Tong Ren Hospital, where she was diagnosed as having bilateral ischemic papillopathy and optic atrophy. There have been few documented cases in medical literature of ocular complications related to use of contraceptives. In 1981, Petursson et al. reported a case of macula edema resulting from oral contraceptives. In animal studies, oral contraceptives have been linked to papilledema and retinal vein obstruction. The case reported here is the 1st to link use of Depo- Provera with ocular complications.     

2%HPMC对兔眼内压及角膜内皮影响的实验研究

报导了2%羟丙基甲基纤维素(HPMC)、1%透明质酸钠(Na-HA)及平衡盐液(BSS)分别注入兔眼前房后,其眼内压、角膜内皮细胞数及内皮细胞形态的变化。证实自制2%HPMC 与进口1%Na-HA 性能基本相同,仅有一过性眼压升高,不损害角膜内皮,能在眼前节手术及人工晶体植入时有效地保护角膜内皮细胞。     

光敏剂辅助的光动力治疗

0 引言 光动力疗法(photodynamic therapy,PDT)是激光技术、光纤技术、光电机械技术、药物制剂技术和现代医学技术有机结合的综合性疾病治疗新方法。近年来,随着这些相关技术的飞速进步,光动力疗法也日趋成熟,并越来越显示出旺盛的生机和活力。光敏剂的应用增加了光动力治疗的选择性(或靶向性)和疗效,较之常规的光动力疗法其优点更加突出。目前,光敏剂辅助的光动力疗法技术已经趋于成熟并逐渐商品化,三种光敏药物
