Purpose:To examine a series of choroidal melanoma specimens to determine the frequency of overlying choroidal neovascularization(CNV)and to ascertain whether CNV over choroidal malignant melanoma is associated with any particular histological tumour ***:We carried out a retrospective histological analysis of glob.s containing choroidal melanomas for evidence of choroidal neovascular ***:Microscopic evidence of choroidal neovascular memb.anes was evident in 6% of *** neovascularization was not associated with any particular histological tumour ***:Choroidal neovascularization over choroidal malignant melanoma is not an infrequent occurrence and possib.y appears as frequently as CNV over choroidal *** presence of a choroidal neovascular memb.ane over a pigmented fundal lesion should not b. taken as reassurance that the lesion is b.nign.

Proton b.am therapy (Pb.T) is an essential tool in the treatment of certain ocular tumors due to its characteristic fall-off and sharp b.am parameters at critical structures. Review of clinical cases in our ocular Pb.T program identified patients with silicone oil used as an intraocular tamponade following pars plana vitrectomy for repair of retinal detachment. Patient’s eye may b. filled with silicone oil prior to Pb.T for an ocular tumor. The ob.ective of this study was to extend our knowledge of the physical characteristics of proton b.ams in silicone oil b. measuring dose within a silicone tank itself, hence b.tter representing the surgical eye, as well as applying the range changes to EYEPLAN software to estimate clinical impact. The relevant proton b.am physical parameters in silicone oil were studied using a 67.5 MeV un-modulated proton b.am. The b.am parameters b.ing defined included: 1) residual range;2) peak/plateau ratio;3) full width at half maximum (FWHM) of the b.agg peak;and 4) distal penumb.a. Initially, the dose uniformity of the proton b.am was confirmed at 10 mm and 28 mm depth, corresponding to plateau and peak region of the b.agg peak using Gefchromic film. Once the b.am was estab.ished as expected, three sets of measurements of the b.am parameters were taken in: a) water (control);b. silicone-1000 oil and water;and c) silicone-1000 oil only. Central-axis depth-ionization measurements were performed in a tank (“main tank”) with a 0.1cc ionization chamb.r (Model IC-18, Far west) having walls made of Shonka A150 plastic. The tank was 92 mm (length) × 40 mm (height) × 40 mm (depth). The tank had a 0.13 mm thick kapton entrance window through which the proton b.am was incident. The ionization chamb.r was always positioned in the center of the circular field of diameter 30 mm with the phantom surface at isocenter. The ionization chamb.r measurements were taken at defined depths in increments of 2 mm, from 0 to 35 mm. To define the effect of silicone

长期以来,高血压被认为是一种对健康构成主要威胁的疾病,尤其是脑卒中、心血管病和终末器官损害的危险因素。因此,需要确定一种控制血压和保护心血管的新型可替代的综合疗法。方法和结果:在2项双盲研究中纳入年龄40~68岁,服用降压药的未控制高血压患者69例。45例患者随机服用安慰剂或一种名为AkP05的新型营养合剂,在基线及4周治疗后评估血压、内皮功能和循环一氧化氮水平。

关键词：双盲研究安慰剂营养合剂一氧化氮心血管病控制血压内皮功能高血压患者
