Background: Panoramic and cephalometric radiography is very important for diagnosis, treatment plan, and evaluation of orthodontic treatment results. Panoramic and cephalometric radiography are frequently performed at the same time, causing DNA damage and chromosome aberration. Purpose: This study aims to analyse the effect of X-ray exposure in panoramic and cephalometric radiography on micronuclei cell numbers. Methods: Laboratory-based analytical study with 60 healthy-male Wistar rats weighing 200–300 grams divided into 6 treatment groups (n=10). The control group: without radiographic exposure, the treatment group 2: using panoramic radiographic exposure followed by cephalometric, and the treatment group 3: using panoramic radiographic exposure and 24 hours later performed cephalometric radiographic. The unit of analysis was the polychromatic erythrocytes of mice cell, were examined 24 hours and 48 hours after irradiation had been finished. The polychromatic erythrocytes were examined using May-Gruenwald-Giemsa staining and 100x magnification under a microscope with 2000 cells per view. Data obtained were analysed using the SPSS 20 version software. The mean and standard deviations were calculated for each clinical parameter, and a one‐way ANOVA statistical test of significance was used. Statistical significance was set at p<0.05. Results: The analysis showed a significant increase (p<0.05) in the number of micronucleus in groups that used panoramic radiographic exposure followed by cephalometric. Conclusion: X-ray radiation can increase the number of micronucleus in polychromatic erythrocyte cells in rats.

ABSTRACT Non-alcoholic fatty liver can be triggered by used cooking oil consumption due to the formation of free radicals and the accumulation of fatty acids in the body. Astaxanthin is a powerful antioxidant that may be able to inhibit the pathogenesis of fatty liver. This study aims to determine the effect of astaxanthin in inhibiting fatty liver (steatosis) and levels of Gamma-Glutamyltransferase (GGT) in male Wistar rats given used cooking oil. An experimental study with Post-test Only Control Group Design was conducted on 36 male Wistar rats aged 3.5-4 months with an approximate bodyweight of 200-210 grams divided randomly into 2 groups. The control group was given 0.42 ml of used cooking oil + 0.5 ml of distilled water, and the treatment group was given 0.42 ml of used cooking oil + 0.2 mg of astaxanthin each day for 14 days. On day 15, blood tests and hepatic histopathology were performed to check  GGT serum levels and steatosis. The comparative test was conducted to compare the results of the control and treatment groups. The results showed that the mean steatosis and GGT levels in the treatment group were significantly lower than the control group. It can be concluded that giving astaxanthin can inhibit fatty liver (steatosis) and increase GGT serum levels in male Wistar rats given used cooking oil.   Keywords: Astaxanthin, Fatty liver, Gamma-glutamyltransferase, Used cooking oil

OBJECTIVE: Surgical scar tensile strength may be influenced by several factors such as drugs, hormones and diet. The purpose of the present study was to determine the influence of a shrimp-enriched diet on the tensile strength of rat scars. METHODS: Forty male Wistar rats were submitted to a 4 cm dorsal skin incision and the wounds were sutured with 5-0 nylon interrupted suture. The animals were divided into two groups: Group 1 (control) received a regular diet, and Group 2 (experimental) received a shrimp-enriched diet. The two diets contained the same amounts of proteins, lipids and carbohydrates. The rats in each group were divided into two subgroups according to the time of assessment of the scar tensile strength: subgroup A, studied on the 5th postoperative day, and subgroup B, studied on the 21st postoperative day. RESULTS: The tensile strength of the scar on the 5th postoperative day was lower in the animals that received the shrimp-enriched-diet (303.0, standard error of mean= 34.1) than in the control group (460.1, SEM = 56.7) (p<0.05). CONCLUSION: A shrimp diet reduces the tensile strength of the scar. The next step of this study will be to clarify the mechanism in which shrimp affects tensile strength.

Abstract: The coffee beans composed of the compound caffeine, palmitic acid, linoleic acid and acid stearic. The content of caffeine in coffee can improve spermatozoa motility that are not motile by inhibiting cyclic nucleotide phosphodiesterase and affects the intracellular levels of cyclic AMP. Spermatozoa quality can be affected by various factors such as stress. In nocturnal animals, dark periode becomes a signal to do activity by suprachiasmatic nucleus. The change in activity of the nocturnal animals from initial condition in the dark then exposed to light can leads to stress. This study was aimed to determine the effect of coffee on the spermatozoa quality of wistar rats which had been exposed to stress. This was an experimental analytical study with a post-test only control group design. The study was conducted for 50 days from September to November 2016. The sample consisted of 9 rats divided into three groups: a control group (P0) is given only exposure to stress in the form of light, the treatment group 1 (P1) is given exposure to stress in the light form and liquid coffee 1 ml / kg and the treatment group 2 (P2) is given exposure to stress in the light form and coffee extracts. The results showed that there were significant differences in the concentration and motility treatment group 1 (P1) to the control group (P0) which is p <0.05 and significant differences in sperm motility treatment group 2 (P2) to the control group (P0) which is p <0.05. Conclusion: Coffee administration could improve the quality of spermatozoa of wistar rats exposed to stress.Keywords: stress, coffee, quality of spermatozoa. Abstrak: Biji kopi tersusun dari senyawa kafein, asam palmatik, asam linoleat dan asam stearik.

Introduction: Diabetes mellitus is a complex and progressive disease which often lead to several debilitating complications that partly caused by by free radicals which can be overcome with antioxidants. Bay leaves contain essential oils, tannins, flavonoids and terpenoids which have considerable antioxidant properties. Therefore, this study aims to determine the effect combination treatment of vildagliptin and bay leaf (Syzygium polyanthum) extract toward pancreatic beta cells density and glycated albumin levels in diabetic male Wistar rats (Rattus norvegicus). Methods: An experimental posttest only control group study was conducted using 36 albino male rats, aged 2-3 months, weighing 180-200 grams. The rats were divided into 2 groups (n= 18) with control group treated with 1.8mg/200g body weight vildagliptin and 2cc placebo (aquabidest) while the treatment group received 1.8mg/200g BW vildagliptin and 250 mg/200g BW bay leaves extract. All treatment lasted for 21 days. Results: The results showed that pancreatic beta cell counts in the treatment group  was significantly higher than the control group  (109.07 ± 20.47 cells/field of view vs 90.87 ± 13.91 cells/field of view; p<0.01). However, the levels of Glycated albumin between two groups were not significantly different (treatment vs control: 17.33 ± 4.51 vs 20.18 ± 4.57; p=0.068). Conclusion: This study suggested that combination treatment of vildagliptin and bay leaf extract increased pancreatic beta cells but did not reduce glycated albumin levels in diabetic male Wistar rats.

Introduction: Monosodium glutamate (MSG) is one of the most widely employed food enhancers. Although the umami compound, controversy persists regarding the effects of MSG intake on body weight. Chronic MSG intake may result in excessive body weight gain and obesity. Consumption of MSG result in organ damage, cardiovascular disease, oxidative stress, and also risk factors for obesity. This study aims to determine the effect of oral MSG on obesity in adult male Wistar rats (Rattus norvegicus).Methods: This true experimental study used the post-test control group design. Twenty-four adult male Wistar rats were randomly divided into four groups: control (received distilled water), Group 1 (MSG 0.378 mg/gr BW), Group 2 (0.756 mg/gr BW) and Group 3 (1.512 mg/gr BW). The obesity parameter was obtained by the Lee index. Kruskal-Wallis test follows by Mann-Whitney test were used to compare the Lee index between groups.Results: Lee’s index mean for each group was 358.4%, 314.1%, 287.8%, and 320.9%, respectively. The Kruskal Wallis test showed a significant difference in the Lee index between groups (p = 0.043). A follow-up test using Mann-Whitney found a significant difference between group 2 and the control group (p = 0.043, p <0.05). The mean of Lee index of group 2 was 70.51% lower than the control group.Conclusion: This study concluded that Lee index was not increased in MSG-treated rats than in the control group after oral MSG intervention for 21 days.

Abstract: Excessive physical activity increases the consumption of oxygen which can result in increased levels of reactive oxygen species (ROS) causing oxidative stress characterized by the elevation of F2-isoprostane as a byproduct of lipid peroxidation. Willow (Justicia gendarussa Burm. f.) has an antioxidant activity that is able to inhibit and break the chain reaction of free radicals and prevent lipid peroxidation. This study was aimed to prove that willow leaf extract could inhibit the elevation of F2-isoprostane levels in male Wistar rats (Rattus norvegicus) urin induced by excessive physical training. This was a true experimental study using 16 male Wistar rats (Rattus norvegicus), aged 2-3 months, weighing 180-200 g as subjects. The control group (P0) was treated with a placebo and excessive physical training, and the treatment group (P1) was treated with the willow leaf extract of 200mg/rat/day and excessive physical training. Before and after 14 days of treatment, the urine samples were collected and their levels of F2-isoprostane 8-isoPGF2α were examined by using enzyme immunoassay kit (EIA). The results showed that the mean level of F2-isoprostane in the control group (P0) before treatment (pretest) was 5.20±0.483 ng / mL while in the treatment group (P1) was 5.46±0.655 ng / mL (P > 0.05). On the other hand, after treatment for 7 days (post-test), the mean level of F2-isoprostane in the control group (P0) was 5.34±0.476 ng/mL and in the treatment group (P1) was 3.61±0.389 ng/mL (P < 0.01). Conclusion: The extract of willow (Justicia gendarussa Burm. f.) leaf could inhibit the elevation of F2-isoprostane levels in male Wistar rats (Rattus norvegicus) urin induced by excessive physical training.Keywords: willow leaf, F2-isoprostane, excessive physical trainingAbstrak: Aktivitas fisik berlebih akan meningkatkan komsumsi oksigen yang dapat mengakibatkan peningkatan kadar reactive oxygen species (ROS) sehingga menyebabkan stres oksidatif yang ditandai dengan meningkatnya F2-isoprostan sebagai salah satu produk peroksidasi lipid.
