ABSTRACT
Glycation and production of free radicals become important mechanisms underlying skin aging. Muntingia calaburais reported to have antioxidant activity in many studies. The effects of M. calabura aqueous leaves extract (MCALE)on oxidative stress and histological changes of mouse model of skin aging were evaluated in this research. Twentymale albino mice were divided into five groups: healthy control; aging control; aging + MCALE 35 mg/kg; aging +MCALE 70 mg/kg; and aging+vitamin C 28 mg/kg. To induce aging condition, oral gavage of D-galactose 500 mg/kg/day were given for 6 weeks. Prior to treatment, blood samples were taken for malondealdehyde (MDA) analyses.MCALE and vitamin C were administered subsequently by oral gavage for 4 weeks and at the end, MDA analyseswere performed again. Routine and van Gieson’s staining were performed to analyze epidermal thickness, fibroblastcell, and density of dermal collagen. Groups received MCALE 70 mg/kg and vitamin C had lower plasma MDAlevel; higher fibroblast number and density of collagen bundles which is reduced in the aging group (p < 0.05).However, epidermal thickness among the five groups was not significantly different. It was concluded that MCALEhad antioxidant and anti-aging effects on D-galactose-induced mouse model of skin aging
ABSTRACT
Esthetic reconstruction of cleft lip nose deformity is a challenging task in surgical management of patients with orofacial cleft. The author reconstructed cleft lip nose deformity effectively using autogenous auricular cartilage and a relatively new graft material of porcine dermal collagen, Permacol(TM). After correction of the deformed lower third of the nose with patient's auricular cartilage, we applied Permacol(TM) to augment the entire nasal dorsum. Three patients were treated and followed for up to five years. All patients improved in nose aesthetics without any inflammatory or immunogenic reaction. The author suggests that the use of Permacol(TM) for nasal profile augmentation in the treatment of cleft lip nose deformity is an alternative surgical strategy with minimal surgical invasiveness. The author report long-term experience with combined use of auricular cartilage and Permacol(TM) in nasal reconstruction for cleft lip nose deformity.
