Treatment of pigment epithelial detachments due to age-related macular degeneration with intra-ocular C3F8 injection*

Purpose: To flatten pigment epithelial detachments (PED) cue to age-related macular degeneration in an attempt to visualize the underlying choroidal neovascularization by fluorescein angiography (FA) and reveal a treatment target. Methods: Nine patients with PED received intravitreal gas injections via the pars plana and postured face down. Fluorescein angiograms were obtained before and after gas injection. In two patients, retinal scotopic sensitivity was also measured. Results: Eight patients demonstrated change in the shape and size of the PED following gas injection. Four patients showed a better delineation of underlying structures on FA. Three patients had focal laser treatment to the newly visible choroidal neovascular complex, but this was successful in only one patient with flattening of the PED. Conclusion: Pigment epithelial detachments can be modified by intravitreal gas injection in some patients, but this treatment did not have a major impact on overall outcome or management.

Comparison of Simulated and in-Vivo Plasma Levels of Cilastatin Following Intravenous in-Line Drug Administration

The primary objective of this work was to establish a method to simulate the plasma levels of cilastatin, a model drug, following an intravenous in-line delivery scheme. In-vivo data in dogs obtained from this work were used to demonstrate the validity of the proposed approach. The in-line drug delivery system consists of a drug containing device which is placed between a large volume parenteral and a patient. Numerous advantages have been identified for this automatic in-line reconstitution delivery system. The numerical convolution integral algorithm was used in this work to perform plasma profile simulation. The results indicated that the simulated cilastatin plasma profile following in-line delivery closely agreed with the in-vivo data.     

经纤支镜局部注射抑瘤仙(Immusyn)治疗肺癌临床观察(附9例报告)

抑瘤仙（Immusyn）是一种甲苯磺酰类的致肿瘤坏死物质，本研究观察经纤支镜注射抑瘤仙治疗大气道肺癌的效果．9例病人均为男性，47～74岁，所有病人均确诊为大气道肿瘤，腺癌4例，鳞癌5例，Ⅲa期3例，Ⅲb期6例．方法，经纤支镜到达肿瘤部位后，局部注入抑瘤仙，每次2～3ml,成每周2次，第1次后每次注药前均钳除上次注药后肿瘤变白的部分，然后再往深部注射，共注射8～16次，疗程30～62夭．结果：注药后第2～4天肿瘤组织变白，与周围分界清楚，钳取白色肿瘤组织时无明显出血，送检为凝固性坏死组织．2例完全缓解，4例部分缓解，1例无效．5例x光提示肺不张病人治疗后有4例复张．所有病人均能忍受治疗，注药后2例病人食欲下降，4例觉轻度嗜睡，可自行缓解．提示，此方法对治疗大气道肺癌（尤其是阻塞气道时）有一定疗效，起效快，选择性高，副作用小．     

酒精胎骨混悬液注射移植促进骨愈合实验研究

用酒精兔胎骨混悬液为植骨材料，以兔双侧桡骨中段３ｍｍ宽骨缺损横断骨折及肱三头肌为动物模型，通过注射将骨植入实验侧骨折端及肌肉内，对侧注入等量生理盐水作自身对照。术后进行免疫学、放射学、组织学及生物力学检查，结果表明：植骨不引起明显免疫排斥反应；植骨侧新骨形成多，骨折愈合快，抗弯应力强度大；肌内诱导成骨明显。酒精胎骨混悬液注射移植是一种简而有效的植骨材料和方法。     

Pyoderma gangrenosum associated with ulcerative colitis and subcutaneous and splenic abscesses

Pyoderma gangrenosum is a rare, chronic, inflammatory ulcerative skin disease of unknown etiology and pathogenesis. It is often associated with systemic disease. We describe a patient with pyoderma gangrenosum associated with ulcerative colitis and aseptic abscesses of the subcutis and spleen, which have been rarely reported previously. These manifestations were cleared by combined therapy with minocycline hydrochloride and diaphenylsulfone.     

荧光光谱法测定复方己酸孕酮注射液中微量组分戊酸雌二醇的含量

复方己酸孕酮注射液为国内常用长效甾体避孕药。制剂中含有己酸孕酮和戊酸雌二醇两种组分,由于戊酸雌二醇的相对含量低,且紫外吸收较弱,给分析带来一定困难。药典含量测
