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.

Purpose: We studied the result and clinical significance of anterior chamber lens implantation in completely vitrectomized eyes without capsular support. Methods: We evaluated 15 aphakic eyes of 15 patients. According to the cause of pars plana vitrectomy, there were 6 eyes for lens dislocation, 5 for intraocular foreign body, and 4 for rhegmatogenous retinal detachment. Results: The final available postoperative best-corrected visual acuity was 0.5 or better in 9 eyes (60%). No statistically significant difference was noted in preoperative and postoperative IOP. The average of postoperative astigmatism was 1.14±0.79D. The most common early complication was temporary increase in IOP, but we could control IOP within normal limit with transient treatment. The postoperative late complications were glaucoma, IOL decentration and cystoid macular edema, but serious postoperative complications such as bullous keratopathy and retinal detachment were not found. Conclusions: The anterior chamber IOL implantation appears to be well tolerated and represents a simple alternative to transscleral fixation of a posterior chamber IOL in completely vitrectomized aphakic eyes.
