The present study aimed to determine the effects of borax (Na2B4O7.10H2O) addition on the changes of histological cerebrum imaging in the brains of white mice (Rattus norvegicus). The current research was an experimental study with randomization of 24 white mice that were divided into four treatment groups with five replications. Borax was dissolved for each treatment with a dose of 19 mg/mouse/day, 26 mg/mouse/day, and 37 mg/mouse/day, and it was administered orally for 14 days. Then, it was analyzed statistically using the Kruskal-Wallis test. The statistical analysis results suggested that there were significantly different results in each treatment group. The control treatment with an administration dose of 26 mg/rat/day had a significantly different result in the worst cloudy swelling degeneration of cerebrum in histopathology imaging on Wistar rats (Rattus norvegicus). Using the Mann-Whitney test, it was found that the dose of borax at 37 mg/rat/day led to significant difference, compared to the other treatment groups, which means that 37 mg/rat/day of borax caused the worst pyramidal cell necrosis in histopathology imaging of the cerebrum on white mice. Borax exposure on Wistar rats (Rattus norvegicus) can cause cloudy swelling at a dose of 26mg/head/day, and pyramidal cell necrosis at a dose of 37 mg/head/day.

Background: Physical exercise aims to improve or maintain physical fitness. However, excessive physical exercise may cause increase of oxidative stress which leads to cellular injury, including in the proximal tubules of kidney. This research aims to find out the effect of single- and repeated- excessive swimming exercise to the kidney histopathology of male wistar rats (Rattus norvegicus). Methods: This research was an experimental study with complete random and post test only control group design. Twenty seven male wistar rats were divided into three treatment groups: control group, single- excessive swimming exercise group (45 minutes for one day), and repeated- excessive swimming exercise group (45 minutes/day for seven days). In the end of the treatment, the kidney of the rats were taken to be analyzed by using hematoxylin-eosin stain. The mean of proximal tubules injury of kidneys were counted by two observers using blinded method. Data were analyzed by using one way anova test. Result: The analysis showed there was a significant difference in the mean percentage of proximal tubules injury between control group and single swimming group as well as the repeated swimming group (Anova p=0,000), also there was significant difference between the treatment groups (p=0,020). The highest average of proximal tubules injury was in the single swimming group. Conclusion: Single- and repeated- excessive swimming exercise causes the proximal tubules injury of kidney.

Abstract: Intraperitoneal adhesion could cause mechanical intestinal obstruction, infertility, lengthened duration of operation, and increased intraoperative risk. To date, there is still no certain method to prevent the occurence of intraperitoneal adhesion. Triamcinolone acetate (TA) is a corticosteroid with long half time. Subjects were 16 Wistar rats (Rattus norvegicus) divided into two groups, the control group and the treatment group. Laparotomy and caecal abration were performed on all rats. The treatment group were given 0.1 mg of TA. All rats were terminated on day-14 and intraperitoneal adhesion was evaluated macroscopically and microscopically. The statistical analysis showed that there was a significant difference in the formation of intraperitoneal adhesion between the two groups macroscopically, but not microscopically. Conclusion: Triamnicolone acetate could diminish the formation of intraperitoneal adhesion.Keywords: intraperitoneal adhesion, triamcinolone acetateAbstrak: Adhesi intraperitoneal dapat menyebabkan obstruksi usus mekanik, infertilitas, memperpanjang waktu operasi, dan meningkatkan risiko terjadinya cidera intraoperatif.

PURPOSE: To compare tissue cicatrization in the tongue of rats using electrosurgery and the cold blade. METHODS: Ten adult male Wistar rats were divided into two groups of 5 animals each, according to the time of sacrifice (3 and 7 days). Each animal had two incisions, one made with a cold blade and the other with an electric blade, both of which were approximately 0.5 mm in length. Following sacrifice of the animals, the tongues were submitted to a histological study in order to classify the presence of angiogenesis, fibroblastic proliferation, epithelial proliferation and inflammatory cells as good, moderate and weak. RESULTS: The wound made with electric blade presented a delay in the healing process and a greater inflammatory response as compared with the cold blade, despite the fact that there was no statistically significant difference (p<0.05). CONCLUSION: There were no significant statistical differences between electrosurgery and the cold blade in relation to angiogenesis, fibroblastic proliferation, epithelial proliferation or the presence of inflammatory cells at any time of evaluation.

Girls between the ages of 9 and 10 begin to experience physical, physiological, and hormonal changes that may lead to internal stress. At this age, children are struggling for autonomy; on the other hand, they may experience emotional instability, and for these reasons, they may be vulnerable in many ways. This experimental study aimed to investigate the effect of resilience training on assertiveness in student girls aged 9–10. Data were collected before, immediately after, and 1 month after the intervention in the control ( n = 40) and intervention ( n = 37) groups. There was a significant difference between the assertiveness of the intervention immediately (26.80 ± 3.73) and 1 month after the intervention (27.05 ± 3.73), and assertiveness significantly increased in the intervention group ( p = .0001). Resilience training leads to improvements in assertiveness in student girls aged 9–10.

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.

An experiment with 15 U.S. Army enlisted military subjects was conducted to compare the performance of an oculometer, head-fixed reticle, and touch panel for data entry on a generic tactical air combat display. The subjects used voice or switch to designate data items on the display that were selected with the oculometer or fixed reticle. The touch panel was included as a standard data entry device. Statistical analysis showed a significant difference in performance for the five configurations at the .0001 level. The reticle/switch, oculometer/switch, and touch panel are significantly faster than the reticle/voice, which in turn is significantly faster than the oculometer/voice. The reticle methods are faster than the oculometer methods. The switch action is faster than voice entry. The touch panel is twice as accurate as the other methods, all of which have about the same spatial accuracy whether oculometer or reticle, voice or switch. However, the oculometer/voice has nearly twice as many selection errors as the other methods.
