Abstract:
This study was aimed to compare the difference of treatment on acute adjuvant arthritis (AA) by using dif-ferent energy densities withirradiation on ST36-Zusanli under the fixed wavelength (650 nm) by the semiconductor. Biological effect and traits of the laser irradiation were also studied. A total of 60 healthy male SD rats were random-ly divided into the normal control group, model group, low energy density group (61.89 J/cm2)and high energy density group (247.57 J/cm2). The Freund's complete adjuvant (FCA) was intradermallyinjected into rats' right hind paw to establish AA rat model. The treatment group was treated with 650nm semiconductor laser irradiation on ST36-Zu-sanli with the energy density of 61.89 J/cm2 and 247.57 J/cm2, respectively. The joint swelling degree, pain thresh-old, TNF-α and IL-1β level changes were observed on thefirst, third and fifthtreatment after modeling. The results showed that compared with the normal group, the joint swelling degree, pain threshold, TNF-α, and IL-1β were obvi-ously increased in the model group (P<0.05). After five times treatment, the semiconductor laser with low and high energy density had effect on acute inflammation. And the high energy density treatment effect had a better effect than the low energy density one (P<0.05). It was concluded that the energy density of 61.89 J/cm2 and 247.57 J/cm2 of semiconductor laser irradiation on ST36-Zusanli can relieve acute inflammatory pain and swelling caused by AA; re-duce the TNF-α and IL-1β concentration levels. Semiconductor laser irradiation had the characteristics of stimula-tion or inhibition, cumulative effect and parabola. Low energy density group obtained the best effect between the third and fifth treatment.
