Beta-methasone valerate, betamethasone dipropionate, hydrocortisone-17-butyrate and triamcinolone acetonide (0.05-0.7% solutions in isopropanol or ethanol) were applied under occlusion in amounts of 0.01, 0.02 and 0.04 ml, respectively. Patch tests were performed on the pretreated skin sites. The patches were removed 24 h after application and the reactions were read 15 min and 24 h later. The intensity of the reactions and the size of the infiltrated areas of the pretreated sites were measured and compared with those of a control patch test. Topical application of corticosteroids was found to have a suppressive effect both on the intensity as well as on the size of the epicutaneous reactions. No marked difference in the suppression effect of the four corticosteroids could be observed.23:T527,Background: Photoaging is a complex biologic process that affects various layers of the skin with the major damage seen in the connective tissue of the dermis. Although rarely fatal, photoaging can significantly contribute to a loss of quality of life; therefore, it deserves attention. Researchers are continually searching for new compounds to develop rejuvenation therapies. Nowadays, the stem cell population has been discovered, and it shows capability to rejuvenate the skin. Material and methods: This was an analytic experimental research conducted on a total of 48 women who were randomized into two groups: 24 women received amniotic membrane stem cell-conditioned medium (AMSC-CM) and the other 24 women received normal saline (NS). We applied the drug for three times with an interval of 2 weeks. Microneedling was used to enhance epidermal penetration. We evaluated the progression of photoaging on Weeks 0, 4, and 8, as well as the side effects. Results: The improvement in photoaging after treatment showed significant better effects with the AMSC-CM than with NS (p < .05). There were minimal transient side effects in either of the study groups. Conclusion: AMSC-CM has the capability to improve clinical photoaging and is a promising option for rejuvenation therapy.24:T522,The effect of three commercially available corticosteroid preparations on ultraviolet (UV) erythema reaction was studied in healthy volunteers. Four series of circles were marked on the skin of their backs. One half of the circle of each series received 0.01 ml of 0.05% betamethasone valerate, 0.1% triamcinolone acetonide and 0.01% hydrocortisone 17-butyrate dissolved in isopropyl alcohol or ethanol and was covered with impermeable plastic. 24 h later, the sites were irradiated with UV light from a Kromayer lamp during 2, 4, 8, 16 or 32 sec. The reactions were evaluated 24 h afterwards. The suppression effect of corticosteroids was expressed as the blanching score (0-3). In a second series of experiments, the reversed sequence was tested: irradiation with UV light was followed by the application of corticosteroids (betamethasone and hydrocortisone). In both series of experiments the blanching effect of the corticosteroids was found to decrease with increasing UV dose. Corticosteroids applied after irradiation were found to have stronger blanching effects. With UV doses of 1 minimum erythema
