OBJECTIVE: This study aimed to assess tissue changes during orthodontic movement after binge-pattern ethanol 20% exposure.METHODS: Male Wistar rats (n = 54) were divided into two groups. The control group (CG) received 0.9% saline solution, while the experimental group (EG) received 20% ethanol in 0.9% saline solution (3 g/kg/day). On the 30th day, a force of 25 cN was applied with a nickel-titanium closed coil spring to move the maxillary right first molar mesially. The groups were further divided into three subgroups (2, 14 and 28 days). Tartrate-resistant acid phosphatase and picrosirius were used to assess bone resorption and neoformation, respectively. Data were compared by two-way ANOVA, Tukey's HSD, Games-Howell and chi-square test. Significance level was set at 5%.RESULTS: There was a decrease in the number of osteoclasts in EG at day 28. The percentage of collagen showed no interaction between group and time.CONCLUSION: Binge-pattern 20% ethanol promoted less bone resorption at the end of tooth movement, thereby suggesting delay in tooth movement.

Photobiomodulation therapy using Light Emitting Diode (LED) with a certain period and intensity can stimulate tissue repair and accelerate orthodontic tooth movement. During remodeling, collagen on periodontal ligaments was formed on the pressure and tension sides. The aim of this study was to investigate the effect of exposure time and observation day of blue LED on the collagen density of periodontal ligament of the pressure and tension sides of Wistar rats. Forty-eight male Wistar rats aged 3-4 months weighing 300-500 grams were divided into four groups: the control group; the group exposed to LED with λ1000 nm of 490 mW/cm2 for 25, 30, and 35 seconds once a day. In addition, their mandibular inter-incisor was administered with thirty-five grams orthodontic force using an open coil spring. The calculations on the collagen density of pressure and tension sides were carried out on days 0, 3, 7, and 14 using the TinEye application. Statistical analysis test was conducted using two-way ANOVA and LSD post hoc test. The results showed a more significant increase in the collagen density of the pressure and tension sides than that of the control group (p <0.05). The collagen density of pressure and tension sides reach the highest point at 30 seconds exposure followed by 35 and 25 seconds. The collagen density of pressure sides decreased on the 3rd day and increased afterward, and the tension sides continued to increase on the 3rd day afterward. The study showed that blue light LEDs were able to increase collagen density on the pressure and tension sides, with optimal exposure at 30 seconds, and it reached the highest point at day 14.

Abstract Background Tramadol is a widely used synthetic opioid. Substantial research has previously focused on the neurological effects of this drug, while the efficacy of various treatments to reduce the associated side effects has not been well studied. This study aimed to evaluate the protective effects of naloxone, diazepam, and quercetin on tramadol overdose-induced seizure and sedation level in male rats. Methods The project was performed with 72 male Wistar rats with an average weight of 200–250 g. The rats were randomly assigned to eight groups. Tramadol was administered intraperitoneally at an initial dose of 25 mg/kg/day. On the 14th day, tramadol was injected at 75 mg/kg, either alone or together with naloxone, diazepam, and quercetin (acute and chronic) individually or in combination. The rats were monitored for 6 h on the last day, and the number, the duration, and the severity of seizures (using the criteria of Racine) were measured over a 6-h observation period. The sedation level was also assessed based on a 4-point criterion, ranging from 0 to 3. Data were analyzed in SPSS software using Kruskal–Wallis, Chi-square, regression analysis, and generalized estimating equation (GEE) tests. The significance level was set at P < 0.05. Results The naloxone-diazepam combination reduced the number, severity, and cumulative duration of seizures compared to tramadol use alone and reduced the number of higher-intensity seizures (level 3, 4) to a greater extent than other treatments. Naloxone alone reduced the number and duration of seizures but increased the number of mild seizures (level 2). Diazepam decreased the severity and duration of seizures. However, it increased the number of mild seizures (level 2). In comparison with the tramadol alone group, the acute quercetin group exhibited higher numbers of mild (level 2) and moderate (level 3) seizures. Chronic quercetin administration significantly increased the number of mild seizures. In the GEE model, all groups had higher sedation levels than the saline only group (P < 0.001). None of the protocols had a significant effect on sedation levels compared to the tramadol group. Conclusion The combined administration of naloxone and diazepam in acute-on-chronic tramadol poisoning can effectively reduce most seizure variables compared to tramadol use alone. However, none of the treatments improved sedation levels.

Background: Infertility can cause low marital satisfaction. Marital satisfaction has an important effect on infertile couples’ health. Objective: This study aimed to assess the effect of relationship enrichment training on improving the marital satisfaction of infertile couples. Methods: This randomized clinical trial was conducted on 50 infertile couples in the infertility center of Fatemieh Hospital in Hamadan, Iran in 2018. Participants were matched for demographic characteristics and randomly assigned to intervention and control groups (each group had 25 couples). Informed consent was obtained from all participants. The Enrich Marital Satisfaction questionnaire and demographic information were used to collect data before the study and two months after the intervention. Two trained midwifery students taught only the intervention group the relationship enrichment topics in seven sessions (each session = 90 minutes). The data were analyzed by SPSS Statistics version 21 using analysis of covariance, independent t-test, chi-square, and Mann–Whitney. The significance level was set at p ≤ 0.05. Results: There was no significant difference in demographic and obstetric information between the two groups (p >0.05). The mean of marital satisfaction in the intervention group significantly increased among women and men from 151.00 ±28.61 to 154.88 ±22.62 and from 152.56 ±27.33 to 159.24 ±22.14, respectively, (p <0.001). Conversely, the mean of marital satisfaction decreased among women and men from 158.13 ±13.86 to 146.25 ±19.53 and from 164.25 ±17.00 to 153.17 ±27.50 in the control group (p=0.02). Conclusion: Relationship enrichment training can be effective in promoting the marital satisfaction of infertile couples.

Summary Introduction Direct pulp capping is an important therapeutic method that has goal to provide formation of dentin bridge and healing process of the pulp. The aim of this study was to investigate the effects of new nanostructural materials based on calcium silicate systems and hydroxyapatite on exposed dental pulp in Vietnamese pigs. Material and Methods The study was conducted on 30 teeth of two Vietnamese pigs (Sus scrofa verus). On buccal surfaces of incisors, canines and first premolars, class V cavities were prepared with a small round bur and pulp horn was exposed. In the first experimental group (10 teeth) the perforation was covered with new nanostructural material based on calcium silicate systems (CS). In the second experimental group, the perforation was covered with compound of calcium silicate systems and hydroxyapatite (HA-CS) (10 teeth). In the control group, exposed pulp was covered with Pro Root MTA® (Dentsply Tulsa Dental, Johnson City, TN, USA) (10 teeth). All cavities were restored with glass ionomer cement (GC Fuji VIII, GC Corporation, Tokyo, Japan). Observation period was 28 days. After sacrificing the animals, histological preparations were done to analyze the presence of dentin bridge, inflammatory reaction of the pulp, pulp tissue reorganization and the presence of bacteria. Results Dentin bridge was observed in all teeth (experimental and control groups). Inflammation of the pulp was mild to moderate in all groups. Neoangiogenesis and many odontoblast like cells responsible for dentin bridge formation were detected. Necrosis was not observed in any case, neither the presence of Gram-positive bacteria in the pulp. Conclusion Histological analysis indicated favorable therapeutic effects of new nanostructural materials based on calcium silicate systems and hydroxyapatite for direct pulp capping in teeth of Vietnamese pigs.

Abstract In this study, we aimed to evaluate the therapeutic effects of autologous platelet-rich plasma (PRP) on deep partial-thickness burns in Bama pigs. Deep partial-thickness burn wounds were created on the back of Bama pigs. The reepithelialization time was compared between the PRP and control groups. The mean score of Ki67 (+) cells and α-SMA (+) vessels, the mean thickness of epidermis and dermis of the healing wounds were determined via H&E staining and immunohistochemical assay. The levels of the growth factors epidermal growth factor (EGF), basic fibroblast growth factor (bFGF), and vascular endothelial growth factor (VEGF) were examined by ELISA. Our data showed that the time to wound reepithelialization was shorter in the PRP group compared with the control group. The thickness of the epidermis was larger in the PRP group compared with the control group. On the 7th and 14th days after the treatment, the mean score of Ki67 (+) cells and α-SMA (+) vessels were higher in the PRP group compared with the control group. The PRP group showed higher levels of growth factors (EGF, bFGF, and VEGF) compared with the control group by ELISA. The results indicated that PRP could improve wound healing process of deep partial-thickness burns in Bama pigs. The PRP increased the thickness of epidermis of the healed wounds, cell proliferation, and angiogenesis. We demonstrated that applying PRP had a greater potential for the treatment of deep partial-thickness burns.
