摘要:Objective: Many topicals claim an efficacious role in skin scar management with limited evidence. Our aim is to present a clear format for functional testing of a skin scarring ointment, using noninvasive and invasive measurements, categorizing findings under the physiological, structural, and mechanical parameters of a scar., Approach: A double-blinded, randomized volunteer research study of 45 subjects receiving an ointment composing of natural ingredients against a widely used antiscarring topical used as a positive control with temporal sequential punch biopsies (up to 16 weeks) was evaluated using noninvasive quantitative devices and validated by gene and protein studies., Results: Outcome measures included physiological, mechanical, and structural features of scars. Significant non-invasive findings included an increase in skin hydration (p?<?0.05) at week (W) 4, 8, and 12, and elasticity (W16; p?=?0.009). These findings were validated by immunohistochemistry (IHC) and quantitative real-time PCR (qRT-PCR). Hyaluronic acid IHC (W4 p?=?0.014, W12 p?=?0.034, and W16 p?=?0.042), qRT-PCR (W16 p?=?0.049); Collagen I (W16 p?=?0.034, and 0.049) IHC and qRT-PCR, respectively. Collagen III qRT-PCR (W12 p?=?0.035, and W16 p?=?0.32); elastin IHC (W12 p?=?0.044); and fibronectin IHC (W4 p?=?0.009, W12 p?=?0.038, and W16 p = 0.026)., Innovation: Utilizing this model allows for quantitative, objective evaluation of any topical, where previously there has been a paucity of relevant methods to evaluate their effect., Conclusions: The positive effect of a topical formulation with an unknown mechanism of action on early cutaneous scar maturation over progressive sequential time points is now evidenced using noninvasive and invasive techniques with the findings categorized on the basis of scarring parameters.
摘要:Every year, millions of people experience burns, suffer from nonhealing wounds, or have acute wounds that become complicated by infection, dehiscence or problematic scarring. Effective wound treatment requires carefully considered interventions often requiring multiple clinic or hospital visits. The resulting costs of wound care are staggering, and more efficacious and cost-effective therapies are needed to decrease this burden. Unfortunately, the expenses and difficulties encountered in performing clinical trials have led to a relatively slow growth of new treatment options for the wound management. Research efforts attempting to examine wound pathophysiology have been hampered by the lack of an adequate chronic wound healing model, and the complexity of the wound healing cascade has limited attempts at pharmacological modification. As such, currently available wound healing therapies are only partially effective. Therefore, many new therapies are emerging that target various aspects of wound repair and the promise of new therapeutic interventions is on the immediate horizon.
摘要:Skin wounds represent an enormous clinical and financial problem in equine. The present study evaluated the effect of Panthenol gel and Mebo ointment on metacarpal wounds healing in donkeys. This experimental study was carried out on eighteen adult donkeys divided into three groups each of six donkeys. All animals were exposed to creation of 2?× 2 cm full-thickness skin wound on the dorsal aspect of the metacarpal regions of both forelimbs. All the wounds were cleaned daily with sterile gauze soaked with sterile distilled water. For the Panthenol gel group, 1 finger tip unit (0.5?g) of Panthenol gel was applied once daily over the wound surfaces. For the Mebo ointment group, 1 finger tip unit (0.5?g) of Mebo ointment was applied once daily over the wound surfaces. For control group, the wounds were cleaned with sterile gauze soaked with sterile distilled water without application of any treatment. The wound healing process was compared by gross observation, geometrical assessments of percentage wound contraction, percentage wound epithelialization, percentage wound healing, and histopathological examination. The wound contraction, wound epithelialization, and wound healing percentages in the Panthenol gel group were significantly higher than other groups and by the end of seventh week, all animals’ wounds in the Panthenol gel group had complete healing. Mebo ointment group had no a significant effect on wound epithelialization and wound healing percentages. In conclusion, the study recommended the use of Panthenol gel as an effective and low-cost wound healing promoting agent for full-thickness skin wounds in donkeys.
摘要:<正>To extend clinical application of skin regeneration in .situ technique with MEBO on split skin thickness donor site a protocol was made for clinical study of treating skin donor site in skin regeneration is situ technique with MEBO in Octobcr of 2005 .The protocol was sent to hospitals that had carried out such study for their conducting the study .The data
