研究目的
Investigating the effects of LED shower irradiation on bone marrow structure and the healing process of dermatome wounds.
研究成果
LED shower accelerates the healing of dermatome wounds and stimulates bone marrow cell proliferation and migration, comparable to the effects of laser shower. This suggests potential applications in promoting tissue growth and wound healing in clinical settings.
研究不足
The study's scope was limited to Vistar rats, and the effects of LED shower on human tissue were not directly investigated. The mechanism of action of LEDs in nonablative light therapy is not fully elucidated.
1：Experimental Design and Method Selection:
The study involved irradiating standard dermatome wounds in Vistar rats with LED shower (λ-470 nm and λ-940 nm) at doses of
2：2-5 J/cm2 for 3 min/day over 10 days. Sample Selection and Data Sources:
42 Vistar rats were used, with 34 exposed to LED shower and 8 as control.
3：List of Experimental Equipment and Materials:
LED set Barva-Flex/BIR with 12 diodes, each with a radiation power of 5 mW.
4：Experimental Procedures and Operational Workflow:
Wounds and femoral bone marrow were examined at intervals post-irradiation using light and electron microscopy, and stereomorphometry.
5：Data Analysis Methods:
Planimetric studies were conducted using the computer application 'Ploshad', version 1.01, with data processing on Microsoft Windows XP-Professional.
