This study was aimed to evaluate the wound healing effects of alpha mangostin ointment using excision wound model. Twenty rats were divided into four groups of five rats each; group I was treated with ointment base (control), whereas group II, group III and group IV were treated with 10% (w/w) povidone-iodine (standard), alpha mangostin 1% (w/w), and alpha mangostin 2 % (w/w) respectively for wound healing evaluations. The size of the wound area was measured, and the reduction in the wound size was calculated, and the tissues examined histologically. The significant difference in the wound size reduction between the control and treated group (p<0.05) was observed in wound healing activity. Histopathological studies showed a lesser number of chronic inflammatory cells, lesser oedema and increased collagenisation in the test than control. This study showed that the alpha mangostin topical ointment could be a promising candidate for the betterment of wound care.

Wound Healing Activity

Wound healing is a dynamic process that can be seriously delayed by many factors including infectious complications. The development of dressings with intrinsic wound healing activity and/or releasing bioactive compounds may help with addressing such an issue. In this study, hyaluronic acid (HA) at different percentages (1–35%) was used to modify chitosan (CS) biological and physico-chemical properties in order to obtain 2D-matrices able to promote healing and protect from infection. HA incorporation in the CS matrix decreased film transparency and homogeneity, but improved film water uptake and surface wettability. The water vapor transmission rate (WVTR) increased up to a 5% HA content, where it reached the highest value (672 g/m2 day), and decreased for higher HA contents. At all of the tested HA concentrations, HA affected mechanical properties providing matrices more flexible than pure CS with benefit for wound care. Pure CS films permitted S. epidermidis adhesion and biofilm formation. That was not true for CS/HA matrices, where HA at concentrations equal to or greater than 5% was able to avoid S. epidermidis adhesion. Fibroblasts adhesion also took benefit from the HA presence in the film, especially at 5% content, where the best adhesion and proliferation was found.

Objectives The aim of this study was to retrospectively review the effectiveness of negative pressure wound therapy (NPWT) in sternal wound healing with the use of the validated Bates-Jensen Wound Assessment Tool (BWAT), and explore the role of NPWT over sternal wounds and future treatment pathways. Methods Data was gathered from patients' medical records and the institution's database clinical management system. Seventeen subjects, who had undergone cardiothoracic surgeries and subsequently consulted the wound care team in one year were reviewed. Fourteen of them were included in the analysis. Healing improvement of each sternal wound under continuous NPWT and continuous conventional dressings was studied. In total, 23 continuous NPWT and 13 conventional dressing episodes were analysed with the BWAT. Results Among conventional dressing episodes, sternal wound improvement was 2.5–3% over 10 days to 3.5 weeks, whereas 4–5% sternal healing was achieved in 5 days to 2 weeks with sternal wire presence. Better healing at 11% in 1 week by conventional dressing was attained after sternal wire removal. In NPWT episodes, 8–29%, 13–24%, and 15–46% of healing was observed in 2 weeks, 3.5 to 5 weeks and 6 to 7 weeks, respectively. Only 39% wound healing was acquired at the 13th week of NPWT in one subject. With sternal wire present, 6%–29% wound healing progress was achieved by NPWT in 1–4 weeks, and 16–23% wound improvement in 2 to 4.5 weeks by NWPT after further surgical debridement. After sternal wire removal, 6–34% sternal wound healing occurred by continuous NPWT for 1–2 weeks, and maximum healing at 46% after 2.5 weeks of NPWT were observed. Conclusions Better wound healing was achieved in the NPWT group in comparison to conventional dressings alone. However, suboptimal sternal wound healing by NPWT alone was observed. Removal of sternal wire may improve the effectiveness of NPWT. Successful tertiary closure after NPWT among subjects supports the important bridging role of NPWT in sternal wound healing. Factors causing stagnant sternal wound healing by NPWT alone are discussed.

Wound Healing Activity

Injuries and wounds are any sorts of damage to the skin or subcutaneous tissue. Usually, any wounds of such sorts are self-healed. Sometimes, there may be a delay in healing, and that delay is caused due to the functional delays in various processes of wound healing. All the Ficus plants show similar activities like the antioxidant, anti-inflammatory and wound healing properties 7including skin conditions like ulcers and rheumatism. The anthelmintic property and immunomodulatory are also seen. The herbal extracts of the same family of Ficus in different plants were investigated for the wound healing activity in the excision wound method, and the extracts showed significant activity compared to the drug. All the extracts showed a better healing ability, but the extract of FBO-100 showed the highest activity followed by FMO followed by FHO and finally the FRO. Overall, the activity of the extract ointment was comparable and was significant compared to the standard drug ointment. The wound closure of the extract ointment treated groups were better and were completed in 12 days, and the activity was more than 96%. The herbal extracts of the same family of Ficus in different plants were investigated for the wound healing activity in the excision wound method, and the extracts showed significant activity compared to the drug. The plants of microcarpa, benghalensis, religiosa and hispida are compared for the activity, and the order showed for the activity was FBO>FMO>FHO>FRO.

Wound Healing Activity

Spirulina is a microalga used in traditional folk medicine in Morocco for the treatment of various health disorders. The wound healing activity of Moroccan Spirulina is unknown. In the current study, aqueous extracts of Spirulina platensis were investigated for acute toxicity and wound healing activity in Swiss Albino mice and White New Zealand rabbits, respectively. The LD50 (amount of substance required to kill 50% of the test population) of the microalga was greater than 5,000 mg/kg. Healing after application of the same amount of ointment on differently induced (mechanical, chemical, and thermal) wounds was about the same, over five weeks. Aqueous extract had remarkable healing activity on rabbits’ skin, possessing significantly greater healing effect for mechanical and chemical burns than controls. Moreover, the hair growing time was faster in treated groups; Spirulina-treated groups did not show any contamination with microbes compared to others. This study affirms that Spirulina platensis can be considered as a potential therapeutic agent for wound healing not only as a complementary medicine but also in conventional medicine.
