objective(s):recent evidence have proposed that tretinoin produced in the gut preferentially promote differentiation of foxp3+treg cells but inhibits th17 lymphocytes, and this may be the main immunomdulatory mechanism of tretinoin in vivo. this study was done to investigate the effects of tretinoin in outbred white mice after challenge with sheep red blood cells (srbc). materials and methods:...
Keloids are skin abnormalities that are characterized by excessive deposition of collagen bundles in the dermis. Patients with keloids complain not only about their cosmetic appearance, but also about continuous itching and/or tenderness associated with chronic inflammation. Degradation of extracellular matrix (ECM) may be upregulated, associated with the expansion of keloids into circumferenti...

Topically applied tretinoin (a retinoid) has been used for over 25 years to treat acne and disorders of keratinization. Now, tretinoin emollient cream, 0.05% (Renova®), may be prescribed for the treatment of photodamaged and chronologically aged skin, in conjunction with appropriate skin care and sun protection routines. Mild to moderate cutaneous side effects to topical tretinoin, such as xero...
Background and Aim: Anti-inflammatory and hypo- pigmenting effects of topical tretinoin and alpha-hydroxy acids have been documented. This study was designed to compare the efficacy of 0.05% tretinion cream with 7% alpha-hydroxy acid in the treatment of ephelides. Methods: In this clinical trial 80 patients with ephelides were selected and allocated into two groups. One group was treated with ...
We administered liposome-encapsulated all-trans retinoic acid (L-ATRA) to 48 patients with refractory hematologic malignancies using an every-other-day schedule for 28 days and doses of 15 to 175 mg/m2. In 19 patients, pharmacology studies were conducted after the first (day 1) and seventh (day 15) doses. In contrast to the decline in tretinoin concentration seen within 3 to 4 days of administr...
Background: It was well known that inhibitory effect of corticosteroids on cutaneous wound healing antagonized by the use of topical tretinoin and systemic vitamin A. However, the exact mechanism of this antagonistic interaction is not yet fully known. The aim of this study was to investigate the effects of topical tretinoin and adapalene application on tissue hydroxyproline content in corticos...
From a clinical point of view, therapy with vitamin A acid originates from the thought that different pharmacokinetics of retinol in systemic or topical treatment would correspondingly entail a different metabolization and development of derivatives of vitamin A acid. Tumor development in the skin of mice caused by benzpyrene as well as therapy of ichthiosiform keratoses indicated that a therap...
