We selected copper chlorophyll and copper sodium chlorophyllin to have experiments of culturing microalga, under the same of illumination and the concentration of nutrition, comparing with copper ion. The results show that under the condition of illumination, a certain quantity of photosensitizer can produce a great quantity of active oxygen, which has strong effect of death; Copper chlorophyll and copper sodium chlorophyllin have very strong influence to growth of microalga.

由于叶绿素铜钠是水溶的，而叶绿素铜是油溶的，导致微藻对它们吸附性质的不同，微藻吸附的少量叶绿素铜钠促进了微藻的生长，而叶绿素铜在低浓度时对微藻的生长具有促进作用，在高浓度时可以抑制微藻生长、甚至杀灭微藻。

光敏剂的性质优劣是决定光疗效果好坏的一个重要因素。

In the first group, photosensitizer was injected intravenously quickly before irradiation as in the previous treatment. In the second group, photosensitizer was injected intravenously slowly throughout the first 15min of irradiation. In the third group, hot fomentation was made on the treated area for 30min, then photosensitizer was injected quickly as in the first group.

3建立PWS组织光学模型，采用Monte carlo方法模拟了临床常用532nm激光在PWS组织中的分布特点，分析皮肤各层组织对其吸收的特点、组织结构(表皮黑色含量、病变血管深度等)以及治疗中氧含量变化对光能流率在PWS组织中分布的影响。

The measured photosensitizer content index can be raised when photosensitizer is injected intravenously slowly during irradiation. Hot fomentation before irradiation can only raise photosensitizer content temporally, but cant increase the photosensitizer content throughout the treatment.

3表皮黑色素含量、扩张血管的深度是影响532nm激光光能流率在PWS皮肤中分布的主要因素，治疗中组织氧含量的变化对532nm激光在PWS皮肤中的光分布没有显著影响。

The photosensitizer hematoporphyrin derivative was given by two different ways: intraperitoneal injection and intratumoral injection. 630 nm He-Ne laser was used to irradiate the tumor after injection.

以血卟啉衍生物作光敏剂，采用腹腔内和瘤内注射2种不同给药方式，后以波长630 nm的激光照射肿瘤组织，观察PDT后肿瘤体积变化和病理改变。

The effects of different factors on the laser-induced graft polymerization on the PET surface were analyzed, and the mechanisms were discussed. The factors were: 1 Monomers with smaller molecules resulted in better modification than polymeric monomers. Acrylamide monomer was chosen as hydrophilic modifier finally; 2 Higher concentration of the monomer solution favored the graft reaction; 3 With the increasing laser fluence, the surface hydrophilicity of PET films increased at first, then decreased. More laser pulses led to a more hydrophilic surface; 4 Benzophenone as a photosensitizer hindered the graft polymerization; 5 The homopolymer retardant of ammonium iron sulfate hexahydrate in a proper concentration retarded the formation of homopolymers and promotes the graft copolymerization; 6 The solvent of monomer solution also affected the graft reaction. Different solvents functioned in different ways. Ethanol can promote the graft reaction because of the activity of hydrogen in its structure; 7 pH value of the monomer solution affects the polymerization rate, and a lower pH value was favorable to the graft reaction.

这些影响因素的作用分别为：1小分子单体的表面改性效果好，确定以丙烯酰胺为亲水性改性单体；2较高的单体溶液浓度有利于接枝反应；3激光能量密度增大，薄膜表面亲水性先显著增强，后又减弱；激光脉冲次数越多，改性后表面亲水性越强；4光敏剂BP对PET表面接枝聚合反应有阻碍作用；5适当浓度的均聚物抑制剂六水合硫酸铁铵能减少单体均聚物的生成，促进接枝聚合；6单体溶液的溶剂也影响接枝聚合的反应进程，不同溶剂的影响作用原理不同，含较活泼氢的乙醇能促进接枝反应；7溶液pH值影响单体聚合速率，pH值较低有利于接枝反应。

The maximum absorption peak was at long wavelength (＞650nm), extinction coefficient achieves 10〓 degree, which was one degree higher than HpD. The study has revealed that CPD photosensitizer appeared blue movement under the relevant body environment. The spectra parameters provided basis for selecting light source of PDT. Measurement system which measured singlet oxygen and its quantum yields within the infare range had been set up and the quantum yields of singlet oxygen for CPD were reported: the quantum yields of singlet oxygen for CPD〓 was the highest (φ=0.83) while he quantum yields of singlet oxygen for CPD〓 was the lowest (φ=0.83). Photobleaching's half life time was studied.
