Lipogenesis was measured in isolated preputial gland cells of female rats after ovariectomy and after the administration of oestradiol benzoate. Ovariectomy decreased preputial gland cell lipogenesis and also altered the pattern of lipid synthesis, producing a relative decrease in the proportion of polar lipids and an increase in the proportion of 'triglycerides'. Although daily administration ...

BACKGROUND The goal of this study was to investigate the anatomy of the peroneal artery and its perforators, and to report the clinical results of reconstruction with peroneal artery perforator flaps. METHODS The authors dissected 4 cadaver legs and investigated the distribution, course, origin, number, type, and length of the perforators. Peroneal artery perforator flap surgery was performed...

A novel postauricular revolving door island flap and cartilage graft combination was employed to correct a large defect on the anterior ear of an 84-year-old man who underwent Mohs micrographic surgery for an antihelical squamous cell carcinoma. The defect measured 4.6 × 2.4 cm and spanned the antihelix, scapha, a small portion of the helix, and a large segment of underlying cartilage, with los...

OBJECTIVE Severe ballistic injuries to the face create complex, composite defects of 2 facial subunits. These injuries have an extremely high economic impact for the Medicare system. The surgical goal with these patients is to restore basic functions of the face with a rapid morphological improvement. Our hypothesis is as follows: Early restoration of facial segments with a single free multiple...

BACKGROUND To establish a relation between the survival rate of island skin flaps submitted to prolonged ischemia and the effect of streptokinase and allopurinol administered after the ischemic period. METHODS A total of 48 male Winstar rats, each weighing between 300 and 350 grams,were separated into four groups of twelve as follows: control, allopurinol, streptokinase and association of all...

Epigallocatechin gallate (EGCG), a polyphenol derived from green tea, is known to have potent antioxidant and anti-inflammatory properties. The aim of this study was to investigate the protective effects of EGCG against ischemia reperfusion injury in the epigastric artery island flap model in rats. The experiment was designed with two groups (control n=40, experiment n=40) of rats with epigastr...

Columellar skin defects may be caused by excision of cutaneous malignancy, trauma, or tissue necrosis associated with surgery. Although columellar skin necrosis rarely occurs following rhinoplasty, this condition might be more common when using an external approach than a closed approach. Columellar skin incision performed with exaggerated tip augmentation may cause columellar necrosis. The nas...
