ABSTRACT The betel nut (Areca catechu L.) is a medicinal plant known by society to halt bleeding. This study was aimed to know the effect of betel nut extract administration on bleeding time after teeth extraction in Wistar male rats. This study was an experimental study. Betel nut extracts were obtained by maceration and evaporation using Rotary vacuum evaporator. The number of samples were 24 Wistar male rats divided into three groups. The treatment group consisted of 8 Wistar male rats. Eight samples of treatment group were fed with betel nut extract at dosage of 13,834 mg/200 g body weight. Dosages were calculated using conversion factor table. The rats teeth were extracted 4 hours after betel nut extract administration. Evaluation of bleeding time was started from the loss of extracted teeth from socket by observing the shed blood to the formation of blood clots in the socket. The bleeding time was calculated using stopwatch. Study results indicated that average bleeding time in treatment group namely 0.6125 (minute.second). The average bleeding time in treatment group did not differ significantly from average bleeding time in positive control group fed with transamine namely 0.3475 (minute.second), and shorter from negative control group fed with 96% ethanol with average bleeding time of 1.79 (minute.second). This study concluded that there was an effect of betel nut extract (Areca catechu L.) administration at dosage of 13,834 mg/200 g body weight on bleeding time after teeth extraction in Wistar male rats.

Abstract Background: Full-thickness wounds are a serious problem which badly affects patients’ life quality and also become the difficult problem for clinicians. Stem cells have great prospects in the treatment of wounds. Our previous experiments proved that autologous basal cell suspension can promote wound healing, and there are epidermal stem cells (ESCs) in basal cell suspension. We then conducted experiments to explore the effect of ESCs on full-thickness wound. Methods: In our study, the rat ESCs were isolated and expanded, and transfected with lentivirus to stably express EGFP. Experimental rats were randomly divided into 2 groups, in the ESCs group, the rat ESCs were sprayed on the Full-thickness wounds of the rats, while in control group, sprayed the PBS on the wound. Wound healing and neovascularization were then evaluated. Colonization, division and differentiation of ESCs on the wound were discovered by immunofluorescence.Results: The result suggested that rat ESCs can colonize, divide and proliferate in the wound. What’s more, the rat ESCs around blood vessels can differentiate into vascular endothelial cells and form a lumen-like structure. Compared with the control group, spraying the rat ESCs on the wound bed can promote angiogenesis and accelerate wound healing. Conclusions: Our study proved that rat ESCs were safe and effective for treating full-thickness wounds, and under certain conditions, ESCs can differentiate into vascular endothelial cells to promote angiogenesis and wound healing.

Introduction. The currently available information on the bischofite mineral pharmacodynamics makes it possible to assume that bischofite-based gels have wound-healing properties. Materials and methods. Experiments were performed on 36 male rats. Using a blade, a linear wound of 50 mm long was modeled. Animals were divided into 4 groups: 1) Control; 2) Bishofit (500 mg of gel with bischofite on the wound area for 7 days); 3) Actovegine (500 mg of Actovegine gel on the wound area for 7 days); 4) Contractubex (500 mg of contractubex gel on the wound area for 7 days). The wound healing effect of the drugs was evaluated through studying the physicomechanical properties, assessing the morphological picture, determining the concentration of hydroxyproline (HP) and calculating the ratio of types I and III collagen. Results. The strongest healing effect on the wound defect, significantly greater than that in the control (p<0.01), was obtained in the group that received bischofite gel (13.70±0.76 N). Actovegine also demonstrated a positive reparative effect (12.60±0.63 N, p<0.05). Significantly lower (p<0.01) healing effect than in the control group was obtained in the group of animals that had received contractubex (9.65±0.59 N). In the calorimetric analysis, it was found that the highest concentration of HP was in the tissues of wound defects in animals treated with contractubex; however, there was no statistically significant difference with the control group. Significantly lower in comparison with the control (p<0.05) concentration of HP, was found in tissues of simulated wounds in animals treated with bischofite gel (79.7% of the control). When assessing the ratio of types I and III collagen in the tissues of the wound defect, when stained with picrosirius red, it was found that by the number of mature collagen fibers, the studied groups can be arranged in the following descending order: Bishofite> Actovegine> Control> Contractubex. A similar trend is demonstrated by the morphological picture of tissues in the area of the wound defect. Conclusion. The study showed that the best results were obtained with external use of bischofite gel. Actovegine has a less significant, but quite pronounced reparative, effect on this model. The least satisfactory results were obtained when applying contractubex.

Background and Aims: Burn injury remain as a major medical problem throughout the world. This injury is accompanied with inflammatory and wound healing responses. Since royal jelly (RJ) has anti-inflammatory and wound healing activity therefore, the aim of this study was to evaluate the repairing effects of RJ on skin burn- damage. Materials and Methods: In an experimental study, 40 male Wistar rats (8 weeks old) were engaged. The animals were divided into five equal groups. Group 1 was considered healthy control. Group 2 (positive control) was treated topically with Silver Sulfadiazine Cream, group 3 received Eucerin as negative control, and group 4, 5 treated with RJ (10 and 30%). Sampling was performed after observing the second-degree burns on the first, seventh and fourteenth days. Then after 28 days, rats were sacrificed and their skin tissues were used for morphological and morphometric assessments. Results: The results of this study showed that the amount and arrangement of collagen type 1 protein was higher in the RJ treatment groups versus control group. Reconstruction and thickening of the epithelium in RJ treated groups confirmed therapeutic effects of RJ. In addition, RJ increased angiogenesis compared to the control group. The woundchr('39')s surface area was reduced in the RJ treatment groups compared to the control group. In addition, fibroblast cell proliferation was increased in the groups receiving RJ versus control. Conclusions: It could be concluded that, RJ induce wound healing effects and might be considered as potential treatment option to improve the burn wound healing.

The use of mouthwash is an effective way to help cure gingivitis. Mouthwash that is often used is mouthwash containing antiseptic. Recently, there has been increasing use of traditional medicines that are considered safer such as areca nuts compared to chemically synthesized agents. The aim of this study was to calculate the difference in the healing of chronic gingivitis due to calculus between gargling using areca nut (Areca catechu) extract and using Chlorhexidine 0.2% solution. This was an experimental test with pre and post-test control group design and involved two treatment groups. A total of 30 subjects with grade 2 gingivitis were being admitted. The first group was given mouthwash with areca nut (Areca catechu) extract and another group with Chlorhexidine 0.2% twice daily for three days. The mean gingival index in the group which gargled using betel nut seed (Areca catechu) extract on the first day was 1,93±0,704 followed by 0,40±0,507 on the second day, and 0,00±0,00 on the third day, on the other hand the mean gingival index in the group which gargled using Chlorhexidine 0.2% solution was 1,93±0,704 on the first day, 0,40±0,507 on the second day, and 0,00±0,00 on the third day. The mean gingival index decreased significantly during observation period in both treatment groups but when being compared to each other there was no significant difference in the healing time of chronic gingivitis in group which gargled using betel nut seed extract (Areca catechu) and Chlorhexidine 0.2% solution.

Introduction. Selenopyran is an organic selenium compound with sharply hydrophobic properties. An increase in solubility in water (and as a consequence – and bioavailability) is possible due to the formation of inclusion complexes with cyclodextrins.Aim. The aim of this work was to study the effect of a gel containing a clathrate complex of selenopyran with β-cyclodextrin on the rate of wound healing on a model of a conditionally aseptic full-thickness planar wound in rats.Materials and methods. The object of the study was a gel containing a clathrate complex of selenopyran with β-cyclodextrin (the content of selenopyran in the gel was 0.1 %). A model of a full-thickness planar wound in sexually mature male rats was used. 20 individuals were divided into 2 groups – intact (without treatment) and experimental (received gel treatment). Efficacy was assessed by the change in wound area at 3, 5, 7, 9, 11 and 14 days after application of wound.Results and discussion. The results of the study showed that the relative area of the wounds in the treated animals by the 3rd day of the experiment was less than in the intact ones. On the fifth day of the experiment, the differences were statistically significant (57.49 ± 12.51 % in treated animals versus 85.27 ± 26.61 % in intact animals). By the 14th day of the experiment, there were practically no differences in the groups of animals.Conclusion. The results obtained indicate that when using a gel containing selenopyran in combination with β-cyclodextrin, it accelerates the transition from the inflammation phase to the proliferation phase. This is most likely due to the antioxidant properties of selenopyran. Considering the lower concentration of selenopyran in comparison with the therapeutic concentrations of other antioxidants (taurine, allantoin), it can be considered as a promising wound healing agent for further study.

Although many previous studies reported that honey promotes wound healing, no study has examined the effects of Japanese honey. The aim of this study was to investigate the effects of three types of Japanese honey, Acacia, Buckwheat flour, and Chinese milk vetch honey, on wound healing in comparison with hydrocolloid dressing. Circular full-thickness skin wounds were produced on male mice. Japanese honey or hydrocolloid dressing was applied daily to the mice for 14 days. The ratio of wound area for the hydrocolloid dressing group increased initially in the inflammatory and early proliferative phases and then decreased rapidly to heal with scarring. However, the ratios of wound area for the Japanese honey groups decreased in the inflammatory phase, increased in the proliferative phase, and decreased in the proliferative phase, and some wounds were not completely covered with new epithelium. These findings indicate that using Japanese honey alone has limited benefit, but since it reduces wound size in the inflammatory phase, it is possible to apply a combined treatment in which Japanese honey is applied only in the inflammatory phase, followed by hydrocolloid dressing from the proliferative phase, which would effectively contract the wound.
