Objective: To observe and explore the effects and mechanism of apoptosis on canine induced by Laser. Try to find a new approach to treat of armpit odor with no traumatism. Method: We used different power of semiconductor Laser to irradiate the black hair canine to observe and evaluate the tissue effects with electroscope, flow cytometry and Tunel technique at different period of time after irradiation. Result: The apoptosis has been observed within the hair follicle cells and apocrine gland cells after irradiation. After repeat irradiation in low power level, more apoptosis has been observed. Conclusion: Apoptosis exists in hair follicle cells and apocrine gland cells after Laser irradiation.

Nowadays, much attention has been paid to keep long-term patency after vascular anastomosis especially for small-caliber vessels in vascular surgery. From these standpoints, low energy CO2 laser was used to make an anastomosis especially for small-caliber vessels. And then an availability of vascular anastomosis by laser could be apparently recognized.

Several photosensitisers are known to accumulate selectively in atheromas, regardless of the size of the involved artery. The new photosensitizer, mono-L-aspartyl chlorin e6 (NPe6), specifically accumulates in the atheroma. In the presence of NPe6, the atheroma could be recognized by detecting the specific fluorescence spectrum of NPe6 using a spectrophotometer. We developed a spectrum analysis system and reported that the fluorescence spectra of NPe6 emitted from atherosclerotic plaques on the descending thoracic aorta were recognized by this analysis system with an angioscopic approach in the animal model of atherosclerosis. We also detected the fluorescence spectrum peak at 675 nm of NPe6 laparoscopically only in parts of the abdominal aorta with an atheroma. This spectrum analysis system is useful to recognize the atheroma, but not to recognize the atherosclerotic lesions of the artery as a whole. So, we developed a fluorescence endoscope. Using the endoscopic analysis system, atheromas on the carotid artery were visualized as reddish spots from inside and outside the artery. Then we developed an epifluorescence stereoscope system, and using this device we visualized small coronary atherosclerosis specifically at the beating heart surface. We extensively examined the effects of photodynamic therapy with NPe6 on the atheroma. We studied the change in the lipid components of the atheroma using Fourier transform infrared (FTIR) microspectroscopy. FTIR microspectroscopic analysis showed a dissociation of ester bonds of cholesterol esters in the atheroma after photodynamic therapy. The framework of the atheroma and the lipids accumulated in the atheroma were destroyed. We also evaluated the change in the elastic framework in the atheroma using scanning electron microscopy. The destruction of the architecture of the elastic fiber network in the atheroma was revealed.

The effects of intravascular low level laser irradiation of He-Ne on rat MCAo-induced cerebral injury were studied. The results showed that control rats (subjected to MCAo injury without laser treatment) at 7d exhibited striatal and cortical brain infarction in the right hemisphere from approximately 3 to 11mm from the front pole. the total infarct volume in this group was 34.5±8.1mm3. For experimental rats (with laser management), the total infarct volume was 29.0±9.0mm3. P was gained less than 0.05. The neurological score of control group was 4.7±0.6 and it was 5.2±1.0 in experimental group, comparison by statistical analysis showed P less than 0.05. The cerebral pathological damages in the control group were more severe than in experimental group. We concluded that the intravascular low level laser irradiation has no remarked complication and is helpful to reduce ischemic damage. There is clinically potential for the application of intravascular He-Ne low level laser irradiation in ischemia stroke.

To obtain a new therapy for port-wine stain (PWS) with good effect and few side effects, the Leghorn chicken combs chosen as the animal models and treated by small dose HpD and variable pulsed 532nm laser were evaluated clinically using four different scoring systems commonly used in previous publication. Result: It was shown significant difference among 5 groups (p<0.01), and the treatment groups have better effect than the control groups. There's also difference among the four treatment groups and the higher dose of HpD has better effect. In all groups the higher the fluency of laser was used, the better the effect produce. Conclusion: The results provide evidence that small dose HpD and variable pulsed 532nm laser can increase the efficacy of treatment in PWS. Increasing the fluency of laser and the dose of HpD can improve the efficacy.
