Pycnogenol (PYC), an extract of pine bark, is known to have photoprotective, antimicrobial, antioxidant, and anti-inflammatory properties. An in vivo study was conducted to evaluate the effects of PYC treatment on wound healing in 48 adult male Sprague-Dawley rats, of which 24 were injected with a single dose of alloxan to induce diabetes. Three (3) excisional skin wounds (1.3 cm x 1.3 cm x 2 mm) were created in each healthy and diabetic animal. One (1) wound in each animal was left untreated, 1 was treated daily with a cleanser (ethacridine lactate) and covered with silver sulfadiazine (SSD), and 1 was treated with PYC powder (30 mg)...

Background and Aims: Resin is a defence against herbivores and a floral reward in a few African and South American species whose bee pollinators collect it for nest construction. Here we describe a new role for floral resin from the Asian genus Kadsura (Schisandraceae). Kadsura tepals tightly cover a globe formed by carpels (in females) or near-fused stamens with fleshy connectives (in male flowers of most, but not all species). Methods: We carried out field observations at four sites in China and used pollinator behavioural assays, chemical analyses and time-calibrated insect and plant phylogenies to investigate the specificity of the interactions and their relationship to floral structure...

Trabeculectomy with antifibrotic treatment is still the most popular incisional procedure for glaucoma filtration surgery (GFS) worldwide. The advent of antifibrotic agents reduced failure due to scarring but resulted in increased complications. Advances in trabeculectomy surgery have been driven by the need to minimise the risk of: (1) complications and (2) surgical failure. This chapter covers preoperative, intraoperative, and postoperative strategies, which improve the outcome of GFS. Strategies to reduce the risk of complications centre on the prevention of postoperative hypotony by minimising the risk of overdrainage, postoperative wound leaks, and poor bleb morphology...

OBJECTIVE: Epithelial cells participate in wound healing by covering wounds, but also as important mediators of wound healing processes. Topical application of the phospholipid growth factor lysophosphatidic acid (LPA) accelerates dermal wound healing and we hypothesized that LPA can play a role in human oral wound healing through its effects on human oral keratinocytes (HOK). DESIGN: HOK were isolated from gingival biopsies and exposed to LPA. The LPA receptor profile, signal transduction pathways, gene expression and secretion of selected cytokines were analyzed...

Traditional management of necrotic digits has been to allow demarcation between viable and nonviable tissues to occur, and thus to indicate the level of amputation required. In this case report, the phalangeal length of the necrotic thumb was maintained in 2 patients who had sustained crush injury. After nonviable soft tissues were debrided, the devitalized bones were covered with soft tissue flaps. All wounds healed without infection. Both cosmetic and functional results of the reconstructed thumbs were satisfactory...

BACKGROUND: Hepatitis B virus (HBV) is the leading cause of liver cirrhosis and hepatocellular carcinoma in Asia and Africa. Existing antivirals cannot cure HBV or eliminate risk of hepatocellular carcinoma. Glucose-regulated protein 78 (GRP78) can inhibit HBV replication, but promote virion secretion and hepatocellular cancer cell invasion. For these reasons, the overall effect of GRP78 on HBV production and whether to utilize the HBV replication-inhibitory effect of GRP78 up-regulation or the hepatocellular cancer cell invasion-inhibitory effect of its down-regulation were further investigated in order to improve the efficacy of current antiviral therapy...

Deep femoral artery pseusoaneurysms (DFAPs) are rare and generally occur after penetrating trauma or surgical procedures. A 36-year old obese man presented with pain in correspondence of the anterior-lateral thigh after 6 months from gunshot wound. Duplex and computed tomography (CT) showed a bilobed right DFAP (maximal diameter 12.9 cm). The patient was managed urgently, under local anaesthesia, by placement in the distal DFA of a Viabahn 8 x 100mm stent-graft (W L Gore & Associates, Inc). The post-operative course was uneventful and the 24-months CT showed regular stent-graft patency and 20 mm DFPA shrinkage...

Surgical extraction of teeth due to dental pathologies is a relatively common procedure in modern man. The healing of the wound that results occurs in gradual and sequential stages, such that the analysis of this repair process can be very useful in forensic investigations on human remains. The following study reports on a particular case where the remodeling of a tooth socket allowed an estimation of the time that had elapsed from the day of the surgical extraction of the tooth to the time of death. The corpse was that of a woman of 34 years...
