Leaf Extracts in Human Keratinocytes. Molecules 2025; 30:2152. [PMID: 40430324 PMCID: PMC12113831 DOI: 10.3390/molecules30102152] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2025] [Revised: 05/07/2025] [Accepted: 05/12/2025] [Indexed: 05/29/2025] Open
Abstract
(1) Background: This study evaluated the potential of an aqueous extract from Quercus robur L. leaves for chronic wound healing. Its composition, rich in bioactive compounds (tannins and flavonoids), confers antioxidant and antimicrobial properties. (2) Methods: The toxicity and ability of the extract to enhance cell migration were tested in human keratinocytes (HaCaT cell line). Additionally, a proteomic analysis was performed on treated cells. (3) Results: The extract exhibited low cytotoxicity (IC50 = 943 µg·mL-1) compared to other plant extracts. At 5 mg·mL-1, it significantly accelerated wound closure at 8 h, surpassing negative control and Reoxcare; however, results were comparable at 12 h. Proteomic analysis identified 117 differentially expressed proteins (21 upregulated, 96 downregulated) involved in essential processes such as cell migration, blood clotting, and cholesterol biosynthesis. Specifically, the extract increased the expression of CYP51A1, LSS, and SQLE, while inhibiting Delta (14)-sterol reductase, key enzymes in cholesterol metabolism, suggesting a potential mechanism for tissue regeneration. (4) Conclusions: The aqueous extract of Q. robur leaves shows promise as a natural therapeutic agent for chronic wound healing, potentially aiding tissue regeneration and modulation of cholesterol metabolism.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Xipayi Kuijie'an herbal enema preparation, a traditional Uyghur medicinal preparation derived from Quercus infectoria galls (QIG), has been clinically employed at Xinjiang Uyghur Medical Hospital for ulcerative colitis (UC) management. Despite its well-documented therapeutic efficacy, the precise mechanisms underlying its pharmacological actions remain poorly understood. AIM OF STUDY This study aimed to elucidate the therapeutic mechanisms of QIG against UC through an integrated approach combining network pharmacology analysis with experimental validation. MATERIALS AND METHODS An integrated approach combining network pharmacology analysis and molecular docking simulations was employed to identify bioactive compounds and their corresponding molecular targets. The effects of QIG on dextran sodium sulfate (DSS) induced colitis were systematically investigated, including disease activity index (DAI), colon length, histopathological observations, as well as the determination of colonic mucosal barrier permeability and biochemical indicators. RESULTS QIG significantly improved DAI and CMDI scores, reduced colonic shortening, decreased colonic mucosal barrier permeability, reduce the release of pro-inflammatory factors and mitigated histopathological changes. CONCLUSION This study demonstrates the efficacy of an integrated approach combining network pharmacology with experimental validation as a robust strategy for elucidating the therapeutic mechanisms of traditional medicines, as exemplified by the systematic investigation of QIG's anti-ulcerative colitis properties.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The dried rhizome of Paris polyphylla Sm. is extensively used by traditional healers in India, China, and Vietnam to treat skin inflammation, cut wounds, uterine and traumatic bleeding, and cancer. AIM OF THE STUDY The traditional use of P. polyphylla rhizomes for treating wounds and bleeding has been reported previously. However, the potential of P. polyphylla in the treatment of diabetic wounds has not yet been explored. Our present study focused on the investigation of the wound-healing activity of P. polyphylla infused ointment in streptozotocin (STZ)-induced diabetic rats to validate the traditional claim. MATERIALS AND METHODS Hydroalcoholic extract of the dried rhizomes of P. polyphylla were quantified by validated and optimized HPTLC (High-performance thin layer chromatography) method for Paris saponin VII, Dioscin and Polyphyllin V. The extract was used to prepare P. polyphylla ointments (5 and 10%). P. polyphylla ointment was subjected to physiochemical analysis and skin irritation test. Thirty STZ-induced diabetic adult male Wistar albino rats were divided into five groups (n = 6) and a circular excision wound was created. P. polyphylla ointment, ointment base (OB), and standard (STD) (Povidone Iodine 10%) were administered topically. The wound area of all groups were recorded every six days and compared with that of control. The epithelization period of each group was recorded. On day 18, the histopathological study of skin tissues of all groups was performed using hematoxylin and eosin (H&E) and Mallory's trichrome (MT). RESULTS Marker analysis and quantification of phytomolecules in hydroalcoholic extract ofP. Polyphylla were found to be of paris saponin VII (3.28 ± 0.08% w/w), dioscin (1.94 ± 0.12% w/w), and polyphyllin V (1.87 ± 0.84% w/w). A physiochemical study of P. polyphylla ointment showed that the prepared ointment was within an acceptable range and was not irritable to the skin. Daily topical administration of 10% P. polyphylla ointment (PP10) for 18 days completely healed the STZ-induced diabetic wounds. On day 18, the 5% P. polyphylla ointment (PP5) showed 99.1 ± 2.9% wound closure, while that of the standard and control was 78.4 ± 7.3% and 18.5 ± 5.9%, respectively. The epithelialization period of PP10 was 18 days, whereas that of the control was 28 days. Histopathological analysis of the progression of PP10 and PP5 wounds showed a decrease in inflammatory cells, regenerated epithelial layer, keratosis layer, hair follicles, fibroblasts, and collagen. Upon collagen intensity quantification of MT stained sections, an increase in collagen density of PP10 and PP5 treated groups was observed, showing accelerated wound healing potential of P. polyphylla extract in diabetic wounds compared to the standard ointment. CONCLUSION This study suggested the potential of P. polyphylla rhizomes derived formulation to treat diabetic wounds, although the plant is traditionally used to treat normal wounds. The results indicate the validation of traditional claim, which has been explored commercially in industrial aspect.

Quercus infectoria Gall Ethanolic Extract Accelerates Wound Healing through Attenuating Inflammation and Oxidative Injuries in Skin Fibroblasts. Antioxidants (Basel) 2024; 13:1094. [PMID: 39334753 PMCID: PMC11428264 DOI: 10.3390/antiox13091094] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2024] [Revised: 08/23/2024] [Accepted: 09/03/2024] [Indexed: 09/30/2024] Open
Abstract
Quercus infectoria Olivier (Fagaceae) nutgall, a traditional Asian medicine, is renowned for its efficacy in treating wounds and skin disorders. Although the gall extract has shown promising results in accelerating wound healing in diabetic animal models, its mechanisms, particularly the effects on redox balance, remain poorly understood. This study aims to investigate the effects and mechanisms of Q. infectoria gall ethanolic extract (QIG) on wound healing in fibroblasts, with a specific emphasis on its modulation of oxidative stress. Hydrogen peroxide (H2O2)-treated L929 cells were used as an in vitro model of oxidation-damaged fibroblasts. QIG exhibited potent antioxidant activity with 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS), and ferric reducing antioxidant power (FRAP) assay values of 305.43 ± 7.48, 508.94 ± 15.12, and 442.08 ± 9.41 µM Trolox equivalents (TE)/µg, respectively. Elevated H2O2 levels significantly reduced L929 cell viability, with a 50% lethal concentration of 1.03 mM. QIG mitigated H2O2-induced cytotoxicity in a dose-dependent manner, showing protective effects in pre-, post-, and co-treatment scenarios. QIG significantly reduced H2O2-induced intracellular reactive oxygen species production and inflammation-related gene expression (p < 0.05). Additionally, at 25 µg/mL, QIG remarkably improved wound closure in H2O2-treated L929 cells by approximately 9.4 times compared with the H2O2 treatment alone (p < 0.05). These findings suggest QIG has potential therapeutic applications in wound healing, mediated through the regulation of oxidative stress and inflammatory response.

Abstract
Patients with diabetes who undergo a kidney transplant are at a great risk of undergoing amputations, usually associated with severe infection and necrosis. The treatment of severe diabetic foot necrosis is challenging in clinic, and the function of the limb is often hugely compromised. A 74-year-old male who had been diagnosed with severe post-renal transplant diabetic foot necrosis refused the option of below-knee amputation from previous surgeons, and requested to keep his left foot. The patient was treated with integrated traditional Chinese medicine (TCM) and Western medicine, with positive results. TCM therapeutic principles included 'clearing heat, removing toxicity, regulating Qi, resolving dampness, activating stagnant blood and nourishing yin as well as tonifying Qi and blood'. Treatment with Western medicine included wound debridement, internal fixation or joint fusion, and use of insulin, antibiotics and vasodilators. The patient was treated with a staged and diverse approach (i.e., a combination of TCM and Western medicine, surgical management and education for diabetic foot care), which ultimately helped the patient achieve limb salvage and regain normal function. A combination therapy of Western medicine and TCM may be a promising approach to heal diabetic foot ulcers.

Abstract
Quercus species have been widely used in traditional medicine, and recently, researchers' attention has focused on galls of the genus Quercus as a source of health-promoting phytochemicals. This review presents a summary of the most recent findings on the phytochemistry and bioactivity of oak galls, following the screening of scientific papers published in two relevant databases, PubMed and Embase, between January 2018 and June 2023. The oak galls are rich in active compounds, mostly gallotannins and phenolic acids. Due to these secondary metabolites, the reviewed studies have demonstrated a wide range of biological activities, including antioxidant and anti-inflammatory actions, antimicrobial properties, tissue-protective effects, and antitumor, anti-aging, and hypoglycemic potential. Thus, oak galls are a promising natural matrix, to be considered in obtaining pharmaceutical and cosmetic preparations used in anti-aging strategies and, together with medications, in the management of age-related diseases. In further evaluations, the valuable functional properties of oak galls, reported mostly in preclinical studies, should be confirmed with clinical studies that would also take into account the potential health risks of their use.

Abstract
BACKGROUND Oral mucositis (OM), an acute inflammation of the oral cavity, is a common complication in patients undergoing invasive myeloblastic chemotherapy or radiation therapy. 5-fluorouracil (5-FU) is one of the most effective therapeutic drugs, but one of the common side effects of 5-FU administration is OM. Unfortunately, no suitable treatment has been found, so far to control its side effects. Studies showed that herbal medicine like Punica granatum var pleniflora (PGP) has medicinal properties such as anti-inflammatory and antibacterial and can be an alternative for the treatment of fungal infection. Accordingly, we decided to investigate the therapeutic effect of PGP in the treatment of OM caused by 5-FU in golden hamsters. METHODS Sixty male golden hamsters were divided into six main group. Chemotherapy with 5-FU at dose of 60 mg/kg was performed at a ten-day duration. Then, cheek pouches of the hamsters were scratched with an 18-gauge sterile needle to induce oral mucositis in animals. On the twelfth day, as a day of intensification of OM, treatment with PGP including topical gel with concentrations of 5% and 10% and oral administration of hydro-alcoholic extract with doses of 125 mg/kg and 250 mg/kg for three- and five-day therapeutic duration were separately started. Finally, samples of cheek pouches in hamsters were collected on 14th and 17th days and histopathologic score (HPS), malondialdehyde (MDA), and myeloperoxidase (MPO) levels were assayed. RESULTS A significant (p < 0.05) decrease in histopathologic score was observed in G10%-, P125-treated groups in comparison to the Ctrl group. Our data showed that treatment with G10% is more potent than P125-treated group. In contrast, histopathologic score in G10%, P125, and P250 treated groups demonstrated almost similar values On the 17th day. However, the levels of MDA and MPO in the treatment groups were enhanced compared with control group (p < 0.05). CONCLUSIONS It is possible that PGP can play protective role in the healing of tissue damage caused by chemotherapy with 5-FU due to the presence of its natural compounds and antioxidant properties.

Abstract
Background Bacterial invasion, protracted inflammation, and angiogenesis inhibition are hallmarks of chronic diabetic wounds, bringing about patient morbidity and rising healthcare costs. For such wounds, there are currently few efficient therapies available. Methods We reported the development of carboxymethyl chitosan (CMCS)-based self-healing hydrogel loaded with ultra-small copper nanoparticles (Cunps) for local treatment of diabetic wound healing. The structure of Cunps was identified by XRD, TEM, XPS and other methods, and the characterization of the synthesized Cunps-loaded self-healing carboxymethyl chitosan (CMCS)-protocatechualdehyde (PCA) hydrogel (Cunps@CMCS-PCA hydrogel) was further investigated. The therapeutic effect of Cunps@CMCS-PCA hydrogel in diabetic wound healing was explored in vitro and in vivo. Results The findings showed that a kind of ultra-small size copper nanoparticles with excellent biocompatibility was prepared. CMCS was chemically conjugated to PCA to form self-healing hydrogels via the formation of an amide bond followed by the loading of ultra-small copper nanoparticles. The obtained Cunps@CMCS-PCA hydrogel showed a typical three-dimensional interlinked network structure with self-healing ability and porosity. It exhibited good biocompatibility in diabetic wounds. Furthermore, Cunps@CMCS-PCA hydrogel group significantly prevented bacterial growth in the skin wound of diabetic rats as compared to model group and CMCS-PCA hydrogel-treated group. After 3 days, no visible bacterial proliferation was observed. It also increased angiogenesis through Cunps mediated activation of ATP7A to prevent induction of autophagy. Furthermore, Cunps@CMCS-PCA hydrogel mainly depended on PCA-induced inhibition on inflammation of macrophage via JAK2/STAT3 signaling pathway. As a result, compared with delayed wound healing process with lower wound healing rate valued at 68.6% within 7 days in the model group, Cunps@CMCS-PCA significantly accelerated wound healing recovery and increased wound healing rate to 86.5%, suggesting that Cunps@CMCS-PCA hydrogel effectively accelerated wound healing. Conclusion Cunps@CMCS-PCA hydrogel offered a new therapeutic approach for quickening diabetic wound healing.

Abstract
CONTEXT The reduction in M2 macrophage polarisation plays a major role during diabetic wound healing. Resveratrol (RSV) can promote the polarisation of M2 macrophages and accelerate diabetic wound healing. However, the specific mechanism by which RSV regulates M2 macrophage polarisation to promote diabetic wound healing is unclear. OBJECTIVE This study evaluated the effectiveness of RSV on diabetic wound healing and analysed the underlying mechanisms. MATERIALS AND METHODS STZ-induced C57/B6 mice were used as a diabetic mice model for a period of 15 days. RSV (10 μmol/L) was injected around the wound to evaluate the effect of RSV on the healing process of diabetic wounds. The human monocyte line THP-1 was used to evaluate the effects of RSV (10 μmol/L) on polarisation of M2 macrophages and the secretion of pro-inflammatory factors. RESULTS In vivo, RSV significantly increased diabetic wound healing (p < 0.05) and make the regenerated skin structure more complete. And it promoted the expression of α-SMA and Collagen I (p < 0.05). Moreover, RSV reduced the secretion of inflammatory factors (TNF-α, iNOS and IL-1β) (p < 0.05) and promoted M2 macrophage polarisation by increasing Arg-1 and CD206 expression (p < 0.01). In vitro, RSV promoted the polarisation of M2 macrophages (p < 0.001) and reduced the secretion of pro-inflammatory factors (TNF-α, IL-6 and IL-1β) (p < 0.05). The therapeutic effects of RSV were all significantly reversed with LY294002 (p < 0.01). DISCUSSION AND CONCLUSIONS RSV has the positive effects on promoting the acceleration and quality of skin wound healing, which provides a scientific basis for clinical treatment in diabetic wound.

JOURNAL OF ETHNOPHARMACOLOGY 2022; 296:115464. [PMID: 35714880 DOI: 10.1016/j.jep.2022.115464] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Revised: 06/03/2022] [Accepted: 06/12/2022] [Indexed: 06/15/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Remijia ferruginea DC. (Rubiaceae) (syn. Cinchona ferruginea A.St.-Hil.) is used in traditional medicine for the treatment of wounds, fever and malaria. AIM This study investigated in vitro the proliferative and antioxidant effects of hydroalcoholic extract of leaves of R. ferruginea (HERF) and in vivo the healing effect of ointment based on HERF. MATERIALS AND METHODS The plant extract was characterized by liquid chromatography/mass spectrometry. Cell proliferation assays and in vitro antioxidant activity were performed. In in vivo assays, wound contraction ax was evaluated, as well as histological analyzes such as cellularity, proportion of blood vessels and collagen type I and III index. In addition, analyzes of the antioxidant enzymes SOD, CAT and GST were performed. RESULTS Our results showed in the chromatographic analysis that catechin, rutin and quercetin were the main phenolic compounds in the plant extract and may be responsible for the antioxidant and proliferative effects (p < 0.05). In addition, these compounds were found in higher concentration in leaves collected in spring. The ointment containing HERF was able to modulate tissue morphology, increasing cell proliferation, blood vessels, being able to stimulate the production of collagen fibers type I and III, (p < 0.05) contributing to scar tissue maturation and resistance. CONCLUSION Our findings indicated that the three doses of HERF tested (1%, 3% and 5%) can modulate the skin repair process, but the best effects were observed after exposure to the highest dose.

Abstract
Background Diabetic wounds are one of the most important issues in diabetic patients. It seems that Juglans regia L. leaf with antioxidant and anti-inflammatory potentials can be profitable for healing of diabetic wounds. The aim of present study was to investigate the topical administration of Juglans regia L. leaf extract in diabetic wound healing. Methods Seventy-five diabetic male rats were randomly divided into 5 groups (n = 15), including: untreated (Control) group, Eucerin group, 2% Juglans regia L. ointment (JRL 2%) group, 5% Juglans regia L. ointment (JRL 5%) group, and Phenytoin group as a reference drug. Sampling was performed at days 7, 14, and 21 after surgery. Evaluation tests included stereology, immunohistochemistry, molecular, and biomechanical. Results Our results showed that the wound closure rate, volumes of newly formed of epidermis and dermis, density of fibroblasts and blood vessels, collagen deposition, density of proliferation cells, expression levels of TGF-β and VEGF genes, and biomechanical characteristics were significantly higher in extract groups compared to control and eucerin groups, however, these changes were considerable in the JRL 5% group (P < 0.05). This is while that the density of neutrophils and expression levels of TNF-α and IL-1β genes in the extract groups, especially in the JRL 5% group, were significantly reduced compared to control and eucerin groups (P < 0.05). Conclusion Topical administration of Juglans regia L. leaf extract, especially in 5% concentration, considerably accelerates diabetic wound healing.

Abstract
Background Parkia clappertoniana Keay (Family: Fabaceae) (P. clappertoniana) fruit husk is commonly used in northern Ghana for wound treatment. However, this folk claim remains to be confirmed scientifically. Objective This study investigated wound healing and antimicrobial effects of P. clappertoniana fruit husk extract (PCFHE) by using excision wound model in rats. Materials and Methods After preparation and phytochemical analysis of PCFHE, it was reconstituted in purified water and emulsifying ointment yielding a wound healing formula (0.3, 1, and 3%). Excision wounds were established in healthy male Sprague-Dawley rats (aged 8-10 weeks; weighing 150–200 g). Rats were randomly assigned into six groups (model, 1% silver sulfadiazine [SSD], vehicle, and PCFHE [0.3, 1, and 3%, respectively]) and topically treated daily until complete wound healing. The endpoints (period of epithelialization, wound contraction, collagen content, erythema index, oedema index, inflammatory cell infiltration, and antimicrobial activity) were assessed for all groups. Minimum fungicidal concentration (MFC), minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and time-kill were assessed. Results Quercetin and catechin were detected in PCFHE. Compared to model and vehicle groups, PCFHE-treatment groups improved wound healing and antimicrobial (MBC, MFC, and MIC) endpoints. PCFHE demonstrated bacteriostatic and fungicidal effects against identified wound contaminants (Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli, and Candida albicans). Conclusion P. clappertoniana fruit husk possesses wound healing and antimicrobial effects in excisional wounds in rats that confirms its folk use, and the reported pharmacological properties of PCFHE are attributable to its quercetin and catechin phyto-constituents.

Abstract
Poor wound healing in individuals with diabetes has long plagued clinicians, and immune cells play key roles in the inflammation, proliferation and remodeling that occur in wound healing. When skin integrity is damaged, immune cells migrate to the wound bed through the actions of chemokines and jointly restore tissue homeostasis and barrier function by exerting their respective biological functions. An imbalance of immune cells often leads to ineffective and disordered inflammatory responses. Due to the maladjusted microenvironment, the wound is unable to smoothly transition to the proliferation and remodeling stage, causing it to develop into a chronic refractory wound. However, chronic refractory wounds consistently lead to negative outcomes, such as long treatment cycles, high hospitalization rates, high medical costs, high disability rates, high mortality rates, and many adverse consequences. Therefore, strategies that promote the rational distribution and coordinated development of immune cells during wound healing are very important for the treatment of diabetic wounds (DW). Here, we explored the following aspects by performing a literature review: 1) the current situation of DW and an introduction to the biological functions of immune cells; 2) the role of immune cells in DW; and 3) existing (or undeveloped) therapies targeting immune cells to promote wound healing to provide new ideas for basic research, clinical treatment and nursing of DW.

Abstract
AIM This study assessed the effects of topical application of the plant Globularia arabica extract on the diabetic rate of wound closure. METHODS The effect of methanol extracts of G. arabica leaf extract on pro-inflammatory and anti-inflammatory cytokines, as well as the rate of wound contraction, hydroxyproline, and collagen content, was examined using an excision model of wound repair in male rats. RESULTS The healing pattern was also highly related to using 10% plant extract and significantly, (p-Values < 0.025) increased wound contraction and increased Hydroxyproline and collagen expression in both non-diabetic and diabetic rats, demonstrating that G. arabica extract possesses potent wound healing capacity. During the early wound healing phase, IL-6 levels were found to be up-regulated by G. arabica treatment. Increased wound contraction augmented hydroxyproline and collagen content, supporting the early wound healing exhibited by G. arabica. One of the ways for speeding wound healing may be the induction of cytokine production. The result of our study shows that the fibroblast cell line treated with 20µg/ml methanolic extract of G. arabica significantly (p-Values < 0.035) increases the cell migration that indicated the high wound healing activity CONCLUSION: Results suggest that G. arabica may be useful in the topical management of wound healing.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The diabetic wound is one of the common chronic complications of diabetes, which seriously affects patients' quality of life and even causes disability and death. Traditional Chinese medicine (TCM) is a unique and precious resource in China, which has a good curative effect and safety. At present, it has been found that Chinese herbal compounds and effective active ingredients can effectively promote diabetic wound healing, and its mechanism needs to be further studied. Signaling pathways are involved in the pathogenesis and progression of diabetic wounds, which is one of the main targets for the pathologic mechanism of diabetic wounds and the pharmacological research of therapeutic drugs. AIM OF THE REVIEW This study has been carried out to reveal the classical signaling pathways and potential targets by the action of TCM on diabetic wound healing and provides evidence for its clinical efficacy. MATERIALS AND METHODS "diabetic wound", "diabetic foot ulcer", "traditional Chinese medicine", "natural plant" and "medicinal plant", were selected as the main keywords, and various online search engines, such as PubMed, Web of Science, CNKI and other publication resources, were used for searching literature. RESULTS The results showed that TCM could regulate the signaling pathways to promote diabetic wound healing, such as Wnt, Nrf2/ARE, MAPK, PI3K/Akt, NF-κB, Notch, TGF-β/Smad, HIF-1α/VEGF, which maintaining inflammatory interaction balance, inhibiting oxidative stress and regulating abnormal glucose metabolism. CONCLUSION The effect of TCM on diabetic wound healing was reflected in multiple levels and multiple pathways. It is envisaged to carry out further research from precision-targeted therapy, provide ideas for screening the core target of TCM in treating diabetic wounds and create modern innovative drugs based on this target.

Abstract
Diabetes is accompanied by inflammation and oxidation. Supplementation of anti-inflammatory and antioxidant compounds can prevent the progression of diabetes. This study aimed to investigate the effects of supplementation of Nannochloropsis oculata microalgae (NOM) on the inflammatory and antioxidant responses in diabetic rats. Sixty male rats were divided into six groups as diabetic and non-diabetic rats receiving 0, 10 and 20 mg/kg of body weight of NOM daily for 21 days. Body weight, the serum concentrations of insulin and glucose and the tissue concentrations of interleukin-1β (IL-1β), tumor necrosis factor-alpha (TNF-α), nuclear factor kappa B (NF-κB), interleukin-6 (IL-6), malondialdehyde (MDA), ferric reducing antioxidant power (FRAP), superoxide dismutase (SOD), glutathione peroxidase (GPx) were assessed. The results showed that induction of diabetes significantly reduced the body weight, the serum concentrations of insulin and the tissue concentrations of SOD, FRAP and GPx while increasing the concentrations of glucose, MDA, IL-1β, IL-6, NF-κB and TNF-α. Daily oral administration of NOM (10 and 20 mg/kg) significantly maintained the body weight, the serum concentrations of insulin and the tissue concentrations of SOD, FRAP and GPx while preventing the increase in the concentrations of glucose, MDA, IL-1β and TNF-α. In conclusion, diabetes caused inflammation and oxidation while NOM worked as a natural anti-inflammatory and antioxidant compound.

Abstract
Diabetic wound is one of the most severe complications of diabetes mellitus (DM). Despite the associated risks of wound healing impairment in diabetes, treatment strategies remain limited. Yeliangen (YLG) is a Chinese formulation mainly composed of the rhizome of Coptis chinensis, the root of Isatis tinctoria, and the leaf of Isatis indigotica. We investigated the wound healing effects of YLG in type 2 diabetic (T2DM) rats, which were induced by intraperitoneal administration of streptozotocin after a high-fat diet for four weeks. 3 × 3 cm2 full-thickness excisional wounds were created on the dorsal surface of rats and then divided to control (DC), negative (DPJ), positive (DPC), and YLG-treated (DYLG) groups. Rat's wounds were treated twice daily for 21 days. Wound area and wound contraction were detected on days 0, 3, 7, 14, and 21. Histopathological examinations were performed by H&E staining and immunohistochemistry (IHC). The biochemical parameters, mRNAs, and protein expressions were analyzed through enzyme-linked immunoassays (ELISA), qPCR, and western blot, respectively. Compared with other groups, the histological changes of wound tissue in the DYLG group were improved, and the expressions of CD31, eNOS, and PCNA were significantly upregulated. Besides, YLG significantly reduced the inflammatory factors' expressions of TNF-α, NF-κB, MMP-9, and IL-1B on days 7, 14, and 21 postwounding. Moreover, YLG induced angiogenesis and neovascularization by significantly increasing the levels of VEGF, TGF-β1, EGF, PDGF, and SDF-1α on days 3, 7, and 14. In conclusion, YLG improved wound healing by reducing inflammation and increasing angiogenesis which may provide an alternative and effective approach for diabetic wound therapy.

Abstract
Kaolinite nanocomposites (NCs) could be utilized as agents for wound healing owing to their efficiency and low toxicity. The present study was conducted to synthesize a novel silver/kaolinite NCs (Ag/Kaol NCs) and investigate their chitosan derivation (Ag/Kaol/Chit NCs) using oak extract. XRD, SEM, EDX, FT-IR, and DLS were employed for the investigation of structural and physio-chemical properties of the synthesized NCs. The obtained results revealed that synthesized Ag/Kaol NCs were mesoporous and spherical with sizes ranging from 7-11 nm. They also demonstrated successful synthesis between silver and kaolinite using the extract. Cytotoxicity and in vitro antibacterial activity were also investigated. The clinical effects of ointments containing the NCs for improving wound healing were studied on the wound area, total bacterial count, histological parameters, and protein expression of some genes. Nanocomposites were safe up to 0.50 mg/mL. The results of in vivo and in vitro antibacterial activity showed that Ag/Kaol NCs, were of antibacterial activity ( ). The results of antioxidant activity indicated that Ag/Kaol NCs have antioxidant structures. Our findings concerning molecular mechanism implied that Ag/Kaol/Chit increased the expression of Wnt/ β -catenin and collagen ( ). In sum, Ag/Kaol/Chit showed antibacterial activity and improved wound healing by decreasing the inflammation and promoting the proliferative phase. The novel NCs showed wound healing properties by decreasing inflammation and total bacterial count and increasing proliferative phase. The application of Ag/Kaol/Chit was suggested as a green agent for improving infected wound healing.
