Objectives: To appraise the effectiveness of platelet-rich fibrin (PRF) in the management of established dry socket in terms of pain, inflammation, and wound healing. Materials and Methods: Two hundred patients with established alveolar osteitis were studied to determine the efficacy of PRF and zinc oxide eugenol (ZOE) for pain control, inflammation reduction, and wound healing. Patients were randomly allocated to Group A (PRF) or Group B (ZOE). Patients were examined on the 1st, 3rd, 7th, and 14th postoperative day and evaluated for pain using visual analogue scale scores, inflammation with a gingival index score, and wound healing through a determination of the number of bony walls exposed. Results: Group A showed better results in terms of pain remission, control of inflammation, and wound healing compared to Group B. Results between groups were statistically significant (P<0.05). Conclusion: PRF is a better alternative than ZOE for the effective management of alveolar osteitis.

Objectives: Cesarean sections are one of the common surgical procedures around the world. Management of cesarean section side effects, including pain, hematoma, delayed wound healing, is of particular importance in maintaining maternal health and ability to care for the baby. The tendency to use complementary medicine strategies is on the rise because of the easy treatment with low side effects. The purpose of this study was to systematically review the efficacy and safety of clinical trials performed in Iran and worldwide on the effect of complementary medicine on pain relief and wound healing after cesarean section. Methods: PRISMA checklist was followed to prepare the report of this systematic review. The search process was carried out on databases on databases of Magiran, SID, Iran Medex, Scopus, Pub Med, Science direct, Medline and Cochrane library using keywords of cesarean, pain, wound healing, Herbal medicine, acupressure, massage, complementary medicine and their Persian equivalent and all possible combinations, from inception until February 2020. We used the Jadad scale to assess the quality of the searched articles. According to the Jadad scale, the articles with a score of at least 3 were included in the study. Results: Finally, 28 clinical trials (with a sample size of 3,245) scored at least 3 on the Jadad scale were included into the analysis. This article reviewed 13 articles on medicinal herbs, 4 articles on massage, 1 article on reflexology, 2 articles on acupressure. Conclusion: According to the present review, the use of medicinal herbs was the most common method of complementary medicine in pain relief and wound healing after cesarean section.

In recent years, an increasing number of reports have explored the wound healing mechanism of these two traditional Chinese herbal medicines- Panax ginseng and Panax notoginseng, but there is no systematic research on the related core functions and different mechanisms in the treatment of wound healing up to now. Based on network pharmacology and meta-analysis, the present work aimed to comprehensively review the commonality and diversity of P. ginseng and P. notoginseng in wound healing. In this study, a wound healing-related "ingredients-targets" network of two herbs was constructed. Thereafter, meta-analysis of the multiple target lists by Metascape showed that these two medicines significantly regulated blood vessel development, responses to cytokines and growth factors and oxygen levels, cell death, cell proliferation and differentiation, and cell adhesion. To better understand the discrepancy between these two herbs, it was found that common signaling pathways including Rap1, PI3K/AKT, MAPK, HIF-1 and Focal adhesion regulated the functions listed above. In parallel, the different pathways including renin-angiotensin system, RNA transport and circadian rhythm, autophagy, and the different metabolic pathways may also explained the discrepancies in the regulation of the above-mentioned functions, consistent with the Traditional Chinese Medicine theory about the effects of P. ginseng and P. notoginseng.

Purpose: The biggest problem of wound healing is a possible occurrence of lesion. Especially, in the case of patients who have a skin injury around exposed body parts, if their treatment period drag on for long time, they can suffer from aftereffects and the costs can be passed on to a society. Therefore, in this research, we investigated the need to develop the effective medicine and appliances for the patients by examining which therapy methods are being applying to the skin damage and what is the advantage and limit by evaluating the patient's satisfaction level. Methods: We carried out an online and offline survey targeting medical teams in order to analyze device for wound care. A total of 125 medical teams applied to the research, and investigate the level of customer satisfaction. Results: The moist dressings are the most used method for wound healing. When it comes to the level of customer satisfaction, biological dressing product also has a high satisfaction level. However its high cost tends to limit the use. Conclusion: This research reached a conclusion that it is need to develop a low cost and high efficiency wound care product considering the fact that its high cost and low efficiency induced economic problems. Generally, it is needed to develop a product for skin regeneration based on biological technologies, not a product just for damage cure.

Background: ginsenoside Rg5 is a rare ginsenoside with known hypoglycemic effects in diabetic mice. This study aimed to explore the effects of ginsenoside Rg5 on skin wound-healing in the Lepr^db/db mutant (db/db) mice (C57BL/KsJ background) model and the underlying mechanisms. Methods: Seven-week-old male C57BL/6J, SLC7A11-knockout (KO), the littermate wild-type (WT), and db/db mice were used for in vivo and ex vivo studies. Results: Ginsenoside Rg5 provided through oral gavage in db/db mice significantly alleviated the abundance of apoptotic cells in the wound areas and facilitated skin wound healing. 50 μM ginsenoside Rg5 treatment nearly doubled the efferocytotic capability of bone marrow-derived dendritic cells (BMDCs) from db/db mice. It also reduced NF-κB p65 and SLC7A11 expression in the wounded areas of db/db mice dose-dependently. Ginsenoside Rg5 physically interacted with SLC7A11 and suppressed the cystine uptake and glutamate secretion of BMDCs from db/db and SLC7A11-WT mice but not in BMDCs from SLC7A11-KO mice. In BMDCs and conventional type 1 dendritic cells (cDC1s), ginsenoside Rg5 reduced their glycose storage and enhanced anaerobic glycolysis. Glycogen phosphorylase inhibitor CP-91149 almost abolished the effect of ginsenoside Rg5 on promoting efferocytosis. Conclusion: ginsenoside Rg5 can suppress the expression of SLC7A11 and inhibit its activity via physical binding. These effects collectively alleviate the negative regulations of SLC7A11 on anaerobic glycolysis, which fuels the efferocytosis of dendritic cells. Therefore, ginsenoside Rg5 has a potential adjuvant therapeutic reagent to support patients with wound-healing problems, such as diabetic foot ulcers.

Low level laser therapy has various therapy effects. This paper performed the basic study for developing the Low Level Laser Therapy Equipment for medical treatment. The apparatus has been fabricated using the laser diode and microprocessor unit. This equipment was fabricated using a micro-controller and a laser diode, and designed to enable us to control light irradiation time, frequency and so on. In this study, the designed device was used to find out how infrared laser diode affected the collagen formation. For in-vivo test, a round wound 1cm in diameter was cut from the test animal whose epidermal and dermal layers were removed. Test animals were relieved for 24 hours after wounds had been excised and then the infrared laser irradiation group was given irradiation therapy over 9 days one 20 min per day. As a result, More collagenosis occurred in the order of infrared laser irradiation and non-irradiation group. Collagenosis is closely related to wound repair and it was found that infrared laser irradiation groups had more collagenosis and was quicker to recover from wound than non-irradiation group.

We previously reported that Hydnocarpi Semen (HS) has a wound healing effect on diabetic foot ulcer lesion in mice. In this study, ethylacetate (EtOAc) fraction from HS extract were evaluated for their wound healing activity by using in vitro acute inflammation model. GC and GC/MS analysis shows that the main constituents in EtOAc fraction are chaulmoogric acid, hydnocarpic acid, and gorlic acid. EtOAc fraction activated macrophages to increase the production of TNF-${\alpha}$. The fraction also increased the production of TGF-${\beta}$ and VEGF, which induced fibroblast activation and angiogenesis. These results suggest that the mechanism that the fraction helps to enhance healing of skin wound is possibly associated with the production of TNF-${\alpha}$, as well as secretion of VEGF, TGF-${\beta}$ and HS may have a new bioactive material for the treatment of skin wound.

In treatment of dentigerous cyst, complete enucleation, histopathologic examination and postoperative care are important to prevent the potential complications (mural ameloblastoma, squamous cell carcinoma). On the other hand, a maxillary impacted supernumerary anterior tooth are removed surgically, owing to the possibility of the cyst formation in future. After the cyst enucleation and extraction of the involved tooth, the wound area sutured and removable resin plate is then applied. In this operation, the postoperative bleeding and infection is likely to occur owing to postoperative accumulation of hematoma & seroma, psychologic stress and other contaminated factor. So, the authors established the immediate rubber & iodoform gauze drainage into the sutured wound of cyst enucleation & tooth extraction for the prevention of postoperative bleeding and infection. The removable resin splint are not used because of the poor cooperation and economic factor. The results were more favorable without the postoperative bleeding & wound infection in a cerebral palsy patient.

Prostaglandin (PG) $E_2$ is an important mediator of skin wound healing without excessive scarring and gastric ulcer healing. However, $PGE_2$ has a short lifetime in vivo because it is metabolized rapidly by 15-hydroxyprostaglandin dehydrogenase (15-PGDH). Ethanol extract of Eriobotryae folium (EFEE) elevated intracellular and extracellular $PGE_2$ levels in HaCaT cells and inhibited 15-PGDH ($ED_{50}$ : $168.4{\mu}g/mL$) with relatively low cytotoxicity ($IC_{50}$ : $250.0{\mu}g/mL$). Real-time PCR analysis showed that mRNA expression of cyclooxygenase (COX)-1 and COX-2 enzymes were increased and prostaglandin transporter (PGT) was decreased in HaCaT cells by EFEE. Moreover, wound healing effect of EFEE ($168.4{\mu}g/mL$) was comparable to that of TGF-${\beta}1$ (300 pg/mL) as a positive control. These results demonstrate that EFEE may be valuable therapeutic materials for the treatment of $PGE_2$ level dependent diseases.

Wound healing is a complex process that includes inflammation, granulation tissue formation, re-epithelialization, and remodeling. We reported previously that BuOH fraction from Hydnocarpi Semen (HS) crude extract exhibited wound healing activity in animal ulcer models. In this study, we investigated whether BuOH fraction activates keratinocyte and fibroblast via wound closure test and migration assay. In the scratch test, BuOH fraction accelerated the closure of a monolayer wound scratch at $100{\mu}g/mL$. After treatment with BuOH fraction for 18 h, keratinocytes showed a increase in migration at $25{\mu}g/mL$, whereas the migration of fibroblast increased significantly at $100{\mu}g/mL$ of BuOH fraction compared to control. The mechanism that the BuOH fraction of HS helps to promote healing by inflammation is possibly associated with the migration of keratinocyte and fibroblast.
