[Effect of Different Concentrations of Moxa-smoke on Lung Function and TNF-α and IL-1 β Levels in Serum and Lung Tissues in Normal Rats]

To study the effect of moxa-smoke inhaling on the respiratory system, so as to provide experimental data and theoretical basis for evaluating the safety of moxa-smoke inhaling during moxibustion treatment.A total of 48 SD rats were randomized into control, low, medium and high moxa-smoke-concentration groups (After 100 days' moxa-smoke inhaling, the contents of TNF-α in the plasma, BALF and lung tissues and IL-1 β in the lung tissue of the low, medium and high concentration moxa-smoke groups, and IL-1 β in the plasma and BALF of the medium and high concentration groups were significantly increased relevant to the control group (Long term inhalation of high concentration of moxa-smoke may lead to inflammatory injury in the lung and bronchial tissues but has no significant effect on the respiratory function in rats. Nevertheless, a good air-ventilation during moxibustion in a treatment room is necessary.
