We checked the change of SOD,MDA peripheral blood in 10 normal people between pre and post treatment. Group A were treated by He-Ne laser combined with drug, group B were treated by semi-conductor laser combined with drug, group C were treated only by He-Ne laser, group D were treated only by semiconductor laser, group E were treated only by drug. Results: The levels of SOD in red cell of psoriatic patients from five groups after treatment were significantly lower than that of controlled group. The levels of SOD of them were significantly increased and nearly closed to that of controlled group; the levels of MDA in red cell of psoriatic patients from five groups after treatment were significantly higher than that of controlled group; the levels of MDA of them are decreased, however, they were still not recovered to normal levels. Conclusions: ILLLI, both He-Ne laser and semiconductor laser, can activate SOD in psoriasis patients and enhance their ability of anti-oxidation.","PeriodicalId":325950,"journal":{"name":"Shanghai International Conference on Laser Medicine and Surgery","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116617092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The retinal circulation was evaluated by means of rapid serial fluorescein angiography (FAG), employing scanning laser ophthalmoscope. FAG was conducted at the rate of 30 frames per seconds in video-tape. Disc-to-macula transit time (DMTT) was defined as the parameter to evaluate the retinal circulation. Diabetic 28 eyes with advanced diabetic retinopathy were examined to measure the DMTT before and after PRP. Normal 30 eyes used as control. Mean DMTT decreased from 9.8±1.5 seconds before PRP to 8.2±1.5 seconds after PRP in 28 diabetic eyes. The value with improvement after PRP was significantly shorter than the value before PRP (p < 0.05). These values before and after PRP were significantly longer than that (3.7±0.7 seconds) in normal 30 eyes (p < 0.01). Retinal circulation is retarded in diabetic retinopathy. The retardation of retinal circulation in diabetic retinopathy improves after PRP, but the value after PRP can not recover until the control level. This study was performed to reveal therapeutic effect to panretinal laser photocoagulation (PRP) for the retardation of retinal circulation in diabetic retinopathy. I investigated the effects of PRP on the velocity of retinal circulation in patients with advanced diabetic retinopathy.","PeriodicalId":325950,"journal":{"name":"Shanghai International Conference on Laser Medicine and Surgery","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129754691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have applied VersaPulse multi-wavelength laser, VascuLight(PhotoDerm) intensive pulse light(IPL), LightSheer semi-conductor laser, Quantum Photo-rejuvenation instruments, Sharplan 1080S ultrapulse CO2 laser, 1030C ultrapulse CO2 laser, Sharplan Erbium laser, Sharplan ruby laser, Laserscope Orion laser, continous and pulsed Nd:YAG laser, continous Nd:YAP laser, Q-switch 1064/532 laser, ClearTouch curative instrument for acnes to treat more than ten thousand of patients. This article discusses these problems and solutions in current laser cosmetic therapy. Firstly, the biggest problem in nevus flammeus treatment is low curative rate. VascuLight IPL and VersaPulse laser can work well together in nevus flammeus treatment. Secondly, three problems in the treatment of nevus pigmentosus are the recurrence from incomplete therapy, scars due to exceeding treatment and serious results because MMs in early stages are mistaken for nevus pigmentosus. So we think that the right way to treat nevi is to remove them by surgery and perform a pathological examination. Thirdly, as to the problems of photo-rejuvenation and rhytidectomy, the sequence of therapy efficiency from better to worse is the ultrapulse CO2 laser, the Erbium laser and IPL. Despite good effect, the CO2 laser does not fit colored people because of serious pigmentation. The Erbium laser, which leads to less pigmentation than people expected, can be chosen to treat thick wrinkles. The photo-rejuvenation cannot reduce wrinkle obviously. Fourthly, the reputation of photo-rejuvenation with IPL has been denigrated by disordered markets and many inferior instruments.","PeriodicalId":325950,"journal":{"name":"Shanghai International Conference on Laser Medicine and Surgery","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125281316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods: 10 dogs were studied. All the samples were divided into two groups: the laser group (5 dogs) and the control group (5 dogs). Acute myocardial ischemia was induced in all the samples, and transmyocardial laser revascularization (TMLR) was only done in the laser group. We compared the difference of improvement in myocardial perfusion between the two groups with single photon emission computed tomograph (SPECT) and observed the patency of the laser channels and heat injures in the tissue adjacent to the channels with light- and electro-scope. Results: After 4 weeks, the recovery of myocardial perfusion was significantly faster in the laser group than in the control group through SPECT (P<0.05). Most of the laser channels drilled with Ho:YAG laser were filled with fibrin. There were amount of microvessels and erythrocytes inside and around the channels. Only slight heat injures were seen in the tissue adjacent to the channels. Only 20-30 watts were needed in TMLR. Conclusions: Transmyocardial revascularization with Ho:YAG laser limits infarct expansion and reduces myocardial ischemia efficiently. TMLR with Ho:YAG laser can become a new technique to treat ischemic heart disease.","PeriodicalId":325950,"journal":{"name":"Shanghai International Conference on Laser Medicine and Surgery","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132042758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
