THERMAL CHARACTERISTICS OF MOXABUSTION AS A FUNCTION OF AIR FLOW
Seung-Ho Yi, Hye-Jung Lee, Hi-Joon Park
In traditional Chinese medicine, moxibustion is one of main therapeutic tools by delivering heat to specific areas
like meridian points. Heat stimulation by a moxa could be achieved by controlling the physical dimension of the moxa
such as mass, shape and density. It also depends on the existence of buffer layers such as ginger and air. A chemical
property of moxa itself is alleged to relate the efficacy of moxibustion.
In order to be effective, the dynamics of moxibustion varies with symptoms.
Practically, controlling temperature or heat amount of moxibustion as a function of time is not easy in hospital, which
might cause inconsistency of moxibustion treatment.
In this study, we measured temperature variation of moxibustion with various air low. Our data showed that
maximum temperature obtained from each moxibustion was increased with the flow. But there was a local maximum
of the temperature at a certain air flow, meaning that the maximum temperature and air flow was not linearly related.
Duration time of moxibustion also demonstrated similar trends.
Our study emphasized that air flow is one of the essential parameters to control temperature of moxibustion and,
in turn, to make moxibustion effective.

Objective: To observe the effect of moxibustion on acupoints Zusanli (ST 36) and Liangmen (ST 31) on cell
proliferation and cell apoptosis of gastric mucosa in rats with stress ulcer, investigatethe mechanism of moxibustion
in promoting the repair of gastric mucosal injury at cellular and molecular levels.
Methods: Sixty healthy Sprague-Dawley rats were randomly divided into four groups: the restraint control group,
model group, moxibustion on acupoints group and moxibustion on non-acupoints group. Water immersion and
restraint stress (WRS) was used to copy the stress ulcer model of rats, radio-immunoassay was used to detect the
content of transforming growth factor (TGF-±), and S-P immunohistochemical assay was adopted to determine the
HSP70 expression, the proliferating cell nuclear antigen (PCNA) and cell apoptosis index in gastric mucosa.
Results: For the WRS-induced gastric ulcer model of rat, the gastric mucosal injury (gastric ulcer index, UI) was
increased, the content of TGF-± was decreased, PCNA was also decreased, HSP70 expression and cell apoptosis
index were all increased (P
