Background: is a well-known medicinal plant that has traditionally been used to treat a variety of ailments, including wound healing. Supporting the traditional claims, wound healing, antibacterial, anti-inflammatory, and antioxidant activities of the crude extracts of different parts of the plant were reported. The aim of this study was to evaluate the wound healing and antibacterial activities of solvent fractions of the menthol leaf extract of .
Methods: Methanol (80%) leaf extract of was fractionated using three solvents; water, n-butanol and chloroform. An ointment containing 2% and 4% of each fraction was formulated and applied to wounds inflicted on rats topically. The wound contraction rate, period of epithelialization, and breaking strength were analysed. In vitro antibacterial activities were tested using the agar diffusion method. The macro-tube dilution technique was used to determine the minimum inhibitory concentration (MIC), and the minimum bactericidal concentration (MBC) was determined by sub-culturing the MIC and concentrations below the MIC.
Results: The 2% and 4% aqueous fractions (AF) significantly increased wound contraction (p 0.001) compared to the negative control and increased tensile strength compared to untreated (p 0.001). Among the three fractions, the n-butanol fraction showed the highest antibacterial growth inhibition, ranging from 8 mm () to 16 mm ().
Conclusion: Data obtained from this study collectively indicated that the aqueous fraction of 80% methanol leaf extract of possesses wound healing and antibacterial activities.

BACKGROUND This study included 32 patients with single missing teeth and alveolar bone defects and aimed to compare outcomes from guided bone regeneration with a gelatin/polylactic acid (GT/PLA) barrier membrane and a Guidor® bioresorbable matrix barrier dental membrane. MATERIAL AND METHODS A total of 32 participants were recruited in the clinical study, with single missing teeth and alveolar bone defects, requiring guided bone regeneration (32 missing teeth in total). They were randomly divided into the GT/PLA membrane group (experimental) and Guidor® membrane group (control) by the envelope method (n=16).

Purpose: This study aims to elucidate the role of pituitary adenylate cyclase-activating polypeptide (PACAP) in Hunner-type Interstitial Cystitis (HIC) and evaluate its potential as a therapeutic target.
Methods: Bladder tissue samples were obtained from HIC patients and normal bladder tissue from bladder cancer patients. PACAP expression was assessed through immunohistochemistry.

Introduction: Soft-tissue defect is commonly seen in immediate maxillary posterior implantation because of tooth extraction wound and tension from bone graft. Bone graft materials exposure has a significant detrimental influence on bone augmentation. However, previous studies lack sufficient evidence to guide wound closure after immediate posterior implantation.

Objectives/hypothesis: Vocal fold (VF) injury and chronic inflammation can progress to scarring, which is notoriously difficult to treat. Human amniotic fluid (AF) has potential for VF wound healing in a rabbit model, and we hypothesized that AF would demonstrate wound healing properties superior to hyaluronic acid (HA) over time.

Traditional wound care preparations frequently face challenges such as complex care protocols, poor patient compliance, limited skin permeability, lack of aesthetics, and inconvenience, in addition to the risk of bacterial infection. We developed a spray film preparation containing nanocellulose and L-serine modified nanosilver, capable of rapidly forming a transparent film on the skin within minutes of application. The incorporation of nanocellulose imparted protective, moisturizing, and breathable properties to the film, allowing for easy removal after use.
