Based on the literature review and theories of biophysical theory, the pathway and mechanism of the heat of sandwiched moxibustion stimulating acupoints are analyzed. It is concluded that the heat of sandwiched moxibustion is transferred to the skin of acupoints by heat conduction and thermal radiation. The heat conduct from the skin to deep tissues and other parts was carried out through the biological heat conduction systems. The investigation combined with theories of biological heat conduction was benefit to the research on clinical mechanisms of indirect moxibustion. In addition to heat effect, the infrared resonance of indirect moxibustion and acupoints may be the base of clinical effects of indirect moxibustion.

The technical structure of a low-cost thermal imaging system (TIM) lunched on a mobile phone was investigated, which consists of a thermal infrared module and mobile phone and application software. The designing strategies and technical factors toward realizing various TIM array performances are interpreted, including sensor cost and Noise Equivalent Temperature Difference (NETD). In the software algorithm, a mechanism for scene-change detection was implemented to optimize the efficiency of non-uniformity correction (NUC). The performance experiments and analysis indicate that the NETD of the system can be smaller than 150 mK when the integration time is larger than 16 frames. Furthermore, a practical application for human temperature monitoring during physical exercise is proposed and interpreted. The measurement results support the feasibility and facility of the system in the medical application.

This study discusses the effects of infrared thermography in dentistry. Infrared thermography allows the quantification of infrared rays and provides useful data for dental care and research. It has been used for the diagnosis of temporomandibular dysfunction (TMD) and proposed as an objective measure of myofascial pain. It is closely related to temperature and produces beneficial objective data. A study of the heat emissions from facial structures has the potential to benefit dental diagnosis of TMD, postoperative inferior alveolar damage, and endodontic and conservative treatments. In this paper, we assessed infrared thermography in dentistry and consider future developments of infrared thermography.

At present, current stimulation, ultra-sound, and light therapy have become effective methods to promote wound healing. Among them, infrared light is the most widely used method and is one of the important methods to promote wound healing. The therapeutic effect of infrared light on wounds is related to the effect of photobiomodulation on cells and molecules on the skin surface, but the mechanism by which photobiomodulation of infrared light promotes wound healing has not been fully elucidated. Therefore, it is necessary to study the action characteristics and the mechanism of photo-biomodulation of infrared light in promoting wound healing. This article reviews the effect of different types of infrared light on wound healing and the mechanism of infrared light in promoting wound healing.

In order to research the infrared radiation characteristics of the skin covering Traditional Chinese acupuncture points, which are NeiGuan in the forearm and LaoGong in the center of the palm, we detected continuously the infrared radiation spectra of the human body surface by using Fourier Transform Infrared Spectroscopy. The experimental results showed that firstly, the differences of the infrared radiation spectra of the human body surface were obvious between individuals. Secondly, the infrared radiation intensity of the human body surface changed with time changing. The infrared radiation intensity in two special wavelength ranges (wavelengths from 6. 79 microm to 6. 85 microm and from 13. 6 microm to 14. 0 microm) changed much more than that in other ranges obviously. Thirdly, the proportions of the infrared radiation spectra changed, which were calculated from the spectra of two different aupuncture points, were same in these two special wavelength ranges, but their magnitude changes were different. These results suggested that the infrared radiation of acupuncture points have the same biological basis, and the mechanism of the infrared radiation in these two special wavelength ranges is different from other tissue heat radiation.

The health-promoting qualities of ultraviolet light have been well recognized, but it also induces deleterious effects from sunburn to skin cancer, Since our enviroment exposes us to both ultraviolet and infrared rays at the same time, the latter is considered to influence to some extent the cutaneous effects of the former. In recent years, it has become increasingly apparent that the biologic effects of one type of radiation may be modified by wavelengths of different energies. Interactions of this kind are complex and occasionally result in true synergy or antagonism. Although there are several reports on these interactions, the results are not in accordance. This study was undertaken to investigate the influence of infrared radiation (IR) on ultraviolet radiation (UVR)-induced skin injury, especially minimal erythema dose (MED). Thirty-five healthy medical students participated in this study between May and June, 1983. One side of the back was exposed to IR with UVR while as a control the other side was exposed only to VVR. The results were summarized as follows : 1. In one experiment treated with IR before UVR, the mean MED-S.D. of the treated site was 17 7+5 3 (sec) and that of the control site was 18. 3-+6. 4 (sec)- The increase of the MED was statistically significant. (p<0. 01], paired t-test) Among the fifteen subjects, the MED was increased in 73% (11/15), and the same in 27% (4/15).

OBJECTIVES: To explore the possible effect of an interaction between summertime heat waves and ozone on cardiopulmonary mortality during the 1994 heat wave in Korea. METHODS: The unusually hot summer of 1994 in Korea was defined as the heat wave in this study. We examined the associations of air pollutants with daily cardiopulmonary deaths between 1991-1995, considering the product term of the heat wave and each pollutant, weather and time trends. RESULTS: During the heat wave, while temperatures were uniformly higher than those of other summers, the within-heat-wave difference in mortality paralleled that in the regional ozone levels. In terms of the influence of the heat wave, the results of ozone were different to those of total suspended particles (TSP) and sulfur dioxide (SO2). The ozone association (relative risk (RR) =1.036; 95% confidence interval (CI) = 1.018-1.054) was observed only under heat wave conditions, while the TSP (RR =1.006, 95% CI = 0.999-1.012) and the SO2 (RR =1.018, 95% CI = 1.011-1.024) associations were found under normal weather conditions (per interquartile increase of each pollutant; results of three pollutants model). The ozone association under heat wave was attributable to the statistical interaction between the heat wave and ozone. CONCLUSIONS: These results support the possibility of a biological synergy between the heat wave and ozone, one that is not evident between the heat wave and other major pollutants like particles or SO2.

OBJECTIVETo investigate the therapeutic effect of infrared radiation (IR) on the skin scald in rats.

METHODSThirty-nine male Wistar rats were used in the study, and they were randomly divided into normal control (C, n = 13), scald (S, n = 13, no treatment after scalding) and treatment (T, n = 13, with IR radiation treatment for 5 days since 2nd post scalding day (PSD) groups. The rats in S and T groups were subjected to deep partial thickness scalding on the back. The cutaneous tissue samples from rat wound in each group were harvested on the 3rd and 7th PSD for pathomorphological examination. DNA synthesis in wound tissue was analyzed by 3H-TdR incorporation method, and the vascular permeability in cutaneous tissue, degree of tissue edema and MDA content were determined by corresponding methods.

RESULTSEpidermal exfoliation, cutaneous ulcer, follicular atrophy and damage, and massive formation of collagen were identified in the skin wound of rats in S group on the 7th PSD compared with C group. The skin in T group was smooth with slight atrophy and a few collagen fibers in follicles. The 3H-TdR incorporation amount in the rats in T group (1856.33 +/- 343.81 cpm/mg) on the 7th PSD was significantly higher than that in S group (1353.95 +/- 274.48 cpm/mg) (P < 0.01). The tissue permeability, edema degree and MDA content in the cutaneous tissue in S group were obviously higher than those in group C, while these indices were markedly lower in T group when compared with those in S group (P < 0.01-0.001).

CONCLUSIONTreatment with IR seemed to be beneficial to the promotion of skin tissue metabolism and tissue repair.
