The purpose of this study was to investigate cardiovascular responses to a bout of aerobic exercise and acute smoking cessation in smoker. nine collegiate male smoker who have been smoking(duration of smoking: 7.5 ± 0.9yrs; number of cigarettes per day: 15.5 ± 1.5) participated in this study. All subjects performed PEI to stimulate Group IV metaboreceptor at immediately after smoking, 24hours after smoking cessation and smoking after a bout of aerobic exercise. they were measured SBP, DBP, HR, SV, CO, TVC using by finometer(FMS co, Netherland). As a result, compared to immediately after smoking, SBP, DBP, and MAP were significantly decreased 24-hours after smoking cessation at rest and PEI(p<0.05). In addition, smoking after a bout of aerobic exercise caused by post-exercise hypotension indicated that SBP was significantly decreased compared to immediately after smoking(p<0.05). also, the changes in DBP and MAP at rest and handgrip exercise were significantly smaller compared to immediately after smoking(p<0.05). Thus, the results showed that smoking cessation during 24-hours and a bout of aerobic exercise relieve excess blood pressure response and enhanced arterial baroreflex in collegiate male smoker. It is concluded that caused exercise pressor reflex by stimulated Group IV may be effective to improve excess blood pressure responses.

본 연구는 치수조직, 치은, 치주인대로부터 배양된 조직을 SP (Substance P)로 4시간, SP, CGRP (Calcitonin Gene-related Peptide), Tumor necrosis factor-α (TNF-α)로 8시간 자극 후 RNase Protection Assay를 시행하고, IL-8의 분비량을 측정해 다음 결과를 얻었다. 1. IL-8 mRNA는 모든세포에서 발현됐다. 2. IL-8 mRNA 발현은 SP (10^(-5)M)와 SP (10^(-8)M)로 4시간 자극 시 증가되지 않았다. 3. IL-8 mRNA 발현은 SP (10^(-4)M)와 CGRP (10^(-6)M)로 8시간 자극 시 증가되지 않았다. 4. TNF-α (2 ng/㎖) 자극 시, IL-8 mRNA 발현이 증가됐다. 5. 치은 세포를 CGRP (10^(-6)M)로 8시간 자극 시, IL-8 분비량이 증가했다 (p < 0.05). 6. 치주인대 세포를 SP (10^(-4)M)로 8시간 자극 시 IL-8 분비량이 증가했다 (p < 0.05). We investigated the secretion of Interleukin-8 (IL-8) from ginviva and periodontal ligament stimulated with Substance P (SP) and Calcitonin Gene-related Peptide (CGRP). Gingiva (GF), periodontal ligament (PDLF) and pulp (PF) tissues were collected from extracted instact 3rd molars. Cultured cells were stimulated with different concentrations of SP for 4 hrs, and stimulated with SP, CGRP and Tumor Necrosis Factor-α (TNF-α) for 8 hrs. Then RNase Protection Assay was carried out. ELISA was performed using supernatants of stimulated cells for quantitative analysis of IL-8. Results were assessed using supernatants of stimulated cells for quantitative analysis of IL-8. Results were assessed using student t-test with significance of P < 0.05. According to this study, the results were as follows: 1. IL-8 mRNA was detected in all type of cells studied (PF, GF and PDLF). 2. IL-8 mRNA expression was not increased after stimulating 4 hrs with SP (10^(-5)M) and SP (10^(-8)M) compared with Mock stimulation in all type of cells studied. 3. IL-8 mRNA expression was not increased after stimulating 8 hrs with SP (10^(-4)M) and CGRP (10^(-6)M) compared with Mock stimulation in all type of cells studied. 4. TNF-α (2 ng/㎖) increased the expression of IL-8 mRNA in all kind of cells studied. 5. The secretion of IL-8 from GF was increased 8 hrs after the stimulation with CGRP (10^(-6)M) (p < 0.05). 6. The secretion of IL-8 from PDLF was increased 8 hrs after the stimulation with SP (10^(-4)M) (p < 0.05). Calcitonin Gene-related Peptide (CGRP) increased Interleukin-8 (IL-8) which plays an important role in chemotaxis of neutrophil in Calcitonin Gene-related Peptide (CGRP) gingival tissue, whereas Substance P increased the secretion of IL-8 from periodontal ligament.

Under the pressure to open the service market as proposed by World Trade Organization, we can easily expect our educational systems for allied health professions will experience a lot of changes in near future. Accordingly, we compared our current educational systems for allied health professions with the foreign ones and mapped out some strategies predicting the forthcoming enormous changes. Major investigations and analysis are summed up as follows, The educational programs for allied health professions which was started in 1963 in Korea are stilled remained as 2 to 3 school years, while the systems in advanced countries have already been changed or been changing from 2 year to 4 year college levels. We can hardly find the uniform educational system or school years for the allied health professions in the world except for Korea. Fortunately, university level four-year programs for the profession was established in 1979 in Won-joo for the first time in Korea. However, there are still only few four-year programs in this country. To meet the rapidly changing needs we have faced in the health areas we should supply appropriate health personnel through various efforts. Now we would like to suggest followings, <Educational goals for the allied health professions> 1) reconfirming characteristics for the educational goals of health professions 2) extending school years for the allied health professions 3) strengthening clinical training and internship 4) expanding opportunities for the continuing education through lifelong education 5) upgrading from old-fashioned technologies to advanced technologies 6) cultivating competencies of health professionals for the global competition <Suggestions for the Development of Allied Health Professions> 1) reforming the school years of educational programs for the allied health professions to meet the global standards 2) expanding the role of junior college programs for the allied health professions through the development of intensive courses in the professions. 3) diversifying and specializing the allied health professions mainly through 4 year B.S. degree programs.
