Chromolaena odorata layered-nitrile rubber polymer transdermal patch enhanced wound healing in vivo.

The objective is to investigate the healing efficacy of a Chromolaena odorata layered-nitrile rubber transdermal patch on excision wound healing in rats. Wounds were induced in Sprague-Dawley rats and were later treated as follows: wound A, the negative control, received no treatment (NC); wound B, the negative control with an empty nitrile rubber patch (NC-ERP); wound C, treated with a C. odorata layered-nitrile rubber patch (CO-NRP); and wound D, the positive control with Solcoseryl gel with a nitrile rubber patch (PC-SG-NRP).

A Review on Antistaphylococcal Secondary Metabolites from Basidiomycetes.

Fungi are a rich source of secondary metabolites with several pharmacological activities such as antifungal, antioxidant, antibacterial and anticancer to name a few. Due to the large number of diverse structured chemical compounds they produce, fungi from the phyla Ascomycota, Basidiomycota and Muccoromycota have been intensively studied for isolation of bioactive compounds. Basidiomycetes-derived secondary metabolites are known as a promising source of antibacterial compounds with activity against Gram-positive bacteria.

Zingiber zerumbet L. (Smith) extract alleviates the ethanol-induced brain damage via its antioxidant activity.

Background: Zingiber zerumbet (L.) Smith belongs to the Zingiberaceae family that is widely distributed throughout the tropics, particularly in Southeast Asia. It is locally known as 'Lempoyang' and traditionally used to treat fever, constipation and to relieve pain.

Alocasia denudata Engler treatment enhance open wound healing activities in Wistar rat's skin.

Ethnopharmacological Relevance: A. denudata is traditionally used to treat various skin disorders, including wounds. It is widely used by the traditional healers as an effective wound treatment.

Gingival and dermal fibroblasts: their similarities and differences revealed from gene expression.

Gene expression profiles in normal human gingival and dermal fibroblasts were investigated using DNA microarrays. Their fundamental characteristics were almost identical, but 5% of their genes were uniquely expressed. These results help us to choose an optimal cell source for effective fibroblast-based cell therapy that is dependent on differential gene expression profiles.

Human serum is an advantageous supplement for human dermal fibroblast expansion: clinical implications for tissue engineering of skin.

Background: Standard fibroblast culture medium usually contains fetal bovine serum (FBS). In theory, unknown risks of infection from bovine disease or immune reaction to foreign proteins may occur if standard culture method is used for future human tissue-engineering development. Human serum (HS) theoretically would be another choice in providing a safer approach and autologous clinically reliable cells.

Formation of in vivo tissue engineered human hyaline cartilage in the shape of a trachea with internal support.

Objective: Treatment and management of congenital as well as post-traumatic trachea stenosis remains a challenge in pediatric surgery. The aim of this study was to reconstruct a trachea with human nasal septum chondrocytes by using the combination of biodegradable hydrogel and non-biodegradable high-density polyethylene (HDP) as the internal predetermined shape scaffold.

Methods: Human nasal septum cartilage was harvested as excessive tissue after elective septoplasty and digested in 0.
