Comparison of Rat Connective Tissue Response to BioMTA, Angelus MTA, and Root MTA

Due to the widespread use of MTA in dentistry and various brands of this product, we decided to compare the three brands available in the country market by their biocompatibility. We divided 20 male Wistar rats into four groups. After local anesthesia and washing, we made two incisions on both sides (4 incisions in total). The experimental groups were Angelus MTA (Angelus, Brazil), BioMTA (CERKAMED, Poland), Root MTA (Dr. Lotfi, Tabriz, Iran), and the control group. The resulting paste was placed in a tube and implanted subcutaneously into male Wistar rats. Wistar rats were sacrificed 7, 15, 30, and 60 days later, with high anesthetic doses. The sample implanted in 10% formalin was stabilized after tissue processing and H&E staining under a microscope. The inflammatory reaction in the tissues received different scores at the beginning of the tube opening. BioMTA had the highest inflammatory response among the groups, but the difference was not statistically significant ( p > 0.05). Also, there was no significant difference between the groups’ granulation and calcification ( p < 0.05). There was a significant difference between BioMTA, Angelus MTA, Root MTA, and control groups in fibrous capsule formation ( p < 0.05). Angelus MTA showed the lowest mean fibrous capsule formation in all periods. The effects of Angelus MTA, Root MTA, and BioMTA on connective tissue were investigated and compared. According to this study, these materials have good biocompatibility. According to the findings and statistical analysis, Angelus MTA has the most biocompatibility.

Introduction/Objective. The aim of this paper was to verify the biocompatibility of the newly synthesized nanostructured material based on calcium aluminate after implantation into the subcutaneous tissue of rats. Methods. The study included 18 rats aged 10?11 weeks, divided into two experimental groups (n = 9). In all animals, incision took place on the back and two pockets of 15 mm in depth were made, in which sterile polyethylene tubes with test materials [calcium aluminate cement (ALBO-CA), calcium silicate cement with the addition of hydroxyapatite (ALBO-CSHA), and mineral trioxide aggregate (MTA) for the control group) were implanted. Six rats of each group were sacrificed in three observational periods (seven, 15, 30 days). Pathohistological analysis included inflammation, bleeding, fibrous capsule, and tissue integrity around the implanted material. Results. After seven days of treatment, ALBO-CA and ALBO-CSHA showed better tissue response compared to MTA, with a statistically significant difference in inflammation intensity (p = 0.2781). The difference in vascular congestion and thickness of the fibrous capsule after implantation of ALBO-CA material compared to MTA was also statistically significant (p = 0.5567). At the end of the 30-day evaluation period, an identical inflammatory response of connective tissue at the site of implanting ALBO-CA, ALBO-CSHA, and MTA (score of 0.7) was recorded. The formation of thick or moderately thick fibrous capsule was found to be the thickest in ALBO-CA (grade 3.7). There were no statistically significant differences between the parameters analyzed after 30 days. Conclusion. Newly synthesized ALBO-CA showed a satisfactory tissue response and confirmed biocompatibility after implantation in subcutaneous tissue of rats.

Liver is an organ with complex metabolism. When the liver is inflamed, cellular immunity will defend against inflammatory agents by stimulating immune cells to produce reactive oxygen species (ROS). Excessive ROS accumulation cause oxydative stress with increased liver malondialdehyde (MDA) level. Some researches showed that purple sweet potato contain flavonoids (anthocyanins) that functioned as antioxydants. This study aimed to show the prophylactic effect of purple sweet potato extract to the liver MDA level of male Wistar rats induced by carrageenan.This study used post-only control group method using 18 male Wistar rats divided into 3 groups: group of rats without treatment, group of rats induced by 0,1 ml of 1% carrageenan by intraplantar injection on day-8, and group of rats given with 872 mg/kgBW of purple sweet potato extract for 7 days and induced by 0,1 ml of 1% carrageenan. In the end of the study, the liver MDA levels were measured by Thio-Barbituric Acid method on each groups.The results of One-Way ANOVA test showed there was no significant difference (p = 0,290) between group of rats without treatment (x̅= 207,50) and group of rats induced by carrageenan (x̅=233,17). Then, there is no significant difference (p = 0.978) between group of rats induced by carrageenan and group of rats given with prophylactic purple sweet potato extract and induced by carrageenan (x̅= 232,50).The conclusion of this study is giving intraplantar injection of carrageenan can increase liver MDA level insignificantly and giving prophylactic purple sweet potato extract has an effect to decrease the liver MDA level of rats induced by carragenan insignificantly because it contains anthocyanins as antioxidants.

Abstract Background: Chemical trauma to the cornea is an emergency condition of the eye that requires early diagnosis and good treatment. Alkaline have ability to saponify fatty acids in cells and cell membranes which can make penetration into the stroma and destroy proteoglycans and collagen in cells. Aloe vera (AV) contains several active substances that are reported to have anti-inflammatory, immunomodulatory, and wound healing effects. AV has been reported to accelerate the healing process of corneal epithelial defects by increasing fibroblast proliferation, collagen production and growth factor production. This study aims to determine the difference between the effect of aloe vera extract with a concentration of 10%, 20%, 40% and BSS on the healing of extensive corneal lesions in white wistar rats alkaline trauma models. Method: This study was an experimental study with a pre and posttest only with control group design in vivo approach to 30 Wistar white rats which were divided into 5 treatment groups for 3 days. Comparative analysis of effectiveness using the ANNOVA test or the Kruskal Wallis test and continued by the post hoc test. Results: Based on the one way ANOVA test there was a statistically significant difference in effectiveness between the five treatment groups on the percentage of corneal wound healing area and TGF-β expression with an assessment of p = 0,000 each. The administration of alloevera (AV) concentration of 20% had a significant difference in percentage of healing of corneal lesions and TGF-β expression compared with other treatment groups with p = 0,000 each. Large differences in the area of corneal lesions in the 40% AV group were -0.45 in the BBS group, 0.146 in the 10% AV group, 0.493 in the 20% AV group. The difference in the AV group 10% was 0.30 in the BBS group, -064 in the AV group 20%, and -0.14 in the AV group 40%. However, TGFβ expression in the normal control group that did not receive treatment was 54.94 (53.21-56-12). TGFβ levels in the BSS group were 10.44, the 10% aloe vera group was 25.43, 47.99 for the 20% aloe vera group and 37.95 for the 40% aloe vera group. Conclusion: There is a difference between the effect of aloe vera extract with concentrations of 10%, 20%, 40% and BSS on the extensive healing of corneal lesions in white wistar rats with alkaline chemical trauma models.
