Koi herpesvirus (KHV) is one of the major pathogen for koi and common carp which cause high mortality and economic losses for the farmer. The purpose of this study was to determine the efficacy of glycoprotein-11 (GP-11) KHV DNA vaccine and compared to GP-25 KHV DNA vaccine. The vaccine in the form of naked DNA plasmidwas delivered by intramuscularly injection to the 3-month-old koi. The fish were divided into six groups, i.e. unvaccinated group (negative control C- and  positive control C+), and vaccinated group (2.5 μg/100 μl of GP-11 (group 1), 7.5 μg/100 μl of GP-11 (group 2), 12.5 μg/100 μl of GP-11 (group 3), and 12.5 μg/100 μl of GP-25 (group 4)). At day 42 post vaccination, all fish of each groups were challenged by injecting KHV titre 10-3 FID50. Number of dead fish was counted everyday after the challenge until 30 days. The results showed that vaccinated fish were had survival rate of 83.33-93.33% (group 2, 3 and 4). It’s show that GP-11 KHV DNA vaccine has high efficacy. As conclusion, GP-11 DNA vaccine could be an alternative DNA vaccine for preventing KHV infection.

ABSTRACT In diabetics there is usually an increase in free fatty acids in the blood and increases the concentration of cholecerols and triglycerides, this condition is called diabetes dyshidemia. This study aimed to find out at the effect of bran milk treatment on the changes of the concetration of cholesterol and triglycerides in diabetetic white wistar rats. Conducted on May 15 until 15 August 2018. Experimental research pre-post test with control design. Subjects of twenty wistar white rats were made diabetic by injecting alloxan 140mg / kg. After being declared diabetic, the rats were divided into four groups, namely group 1 (negative control), group 2 (positive control), group 3 (bran milk 0.54g / 200 gr) and group 4 (bran milk 1.08g / 200gr). The intervention was given for fourteen days. The data analysis used the paired T-test to test the subject before and afterthe treatment and the One-Way ANOVA test was used to test the difference between the groups. The research results indicated that  the treatment with bran milk there were no significant differences in cholesterol and triglyceride concentrations in the four groups. But when viewed from changes before and after the intervention showed that group 4 (bran milk 1.08g / 200gr) decreased cholesterol concentration and in group 3 (bran milk 0.54g / 200gr) a decrease in triglycerides was better than group 1 (control negative) and group 2 (positive control). It was concluded that the administration of bran milk can reduce the concentration of cholesterol and triglycerides in wistar diabetic white rats.Keywords : Bran milk, Cholesterol, Triglycerides, Rats, Diabetic

GP-11 KHV DNA vaccine is a vaccine that can be used to induce immunity against the KHV virus (Koi herpesvirus). Vaccination through feed is an alternative way of administering vaccines. The study aimed to examine the effect of giving KHV GP-11 DNA vaccine through feed with different frequencies to KHV infection. The frequency of vaccine administration is GP-11 vaccination once a week; GP-11(1x), GP-11 vaccination twice a week; GP-11(2x), GP-11 vaccination three times a week; GP-11(3x), GP-25 vaccinations three times a week; GP-25(3x), negative control (without KHV test) and positive control (KHV tested). The fish were kept for 28 days after vaccination and then continued with the KHV challenge test for 28 days. The weight of carp ranges from 13.82±2.37 g maintained with a density of 15 fish/aquarium. The results showed that vaccine treatment was able to induce an immune response as indicated by the number of white blood cells, lysozyme activity and post-vaccination antibody titer showed a significant effect compared to controls. Likewise, after the challenge test, supported by IFNγ and IgM gene expression parameters after the challenge test showed the highest value of vaccine treatment rather than control. The efficacy of vaccine was showed by RPS value (%) in each vaccine treatment obtained GP-11(1x) value of 44.7±3.7a, GP-11(2x) of 78.9±18.2b, GP-11(3x) 85.6±12.6b and GP-25(3x) 79.5±18.1b. It was concluded that administering the GP-11 vaccine frequency 2 times a week provides protection as strong as giving a vaccine frequency 3 times a week.Keywords: common carp, DNA vaccine, frequency of administration, koi herpesvirus

Background: Electromagnetic fields (EMF) with different intensities are widely used at home, offices and public places.Today, there is a growing global concern about the effects of human exposure to EMFs. Epilepsy is one of the most common chronic neurological diseases, affecting 50 million people of all ages worldwide. We aimed to investigate the effect of exposure to Wi-Fi radiation on epileptic behavior of rats.Methods: 147 male rats, weighing 200-250 g, were divided into seven groups; negative control (no intervention), sham 1(distilled water), positive control (Pentylentetrazol [PTZ]), intervention group 1 (PTZ + Wi-Fi “off”), sham 2 (distilled water + Wi-Fi “off”), sham 3 (distilled water + Wi-Fi “on”), and intervention group 2 (PTZ + Wi-Fi “on”). The rats were exposed to Wi-Fi for 2h at a distance of 30cm from a commercial Wi-Fi router. Convulsive behaviors of rats were monitored and scored based on the intensity and type by measuring latency/threshold time, number of convulsions, sum of scores and durations of seizure, and duration of score 6 seizure. Kruskal-Wallis and Mann-Whitney U-tests were used to analyze the data.Results: Convulsion was observed in interventions Group 4 and Group 7, and positive control. The mean number of events, and sum of scores were significantly different in intervention 2 than other two groups. However, the differences in mean threshold, mean sum of durations and “ time to show convulsion with score 6 ” were not statistically significant (P>0.05).Conclusion: Due to limitations of our study including the sample size, these findings should be interpreted with caution.  In this study, exposure to 2.4 GHz Wi-Fi radiation showed significant beneficial effects on the epileptic behaviour of rats. More experiments are needed to verify if these exposures can be used as a therapeutic approach for amelioration of seizures in epilepsy.

Objective: To determine the differences of germinal epithelial testicular cell apoptosis in white Sprague Dawley strain rat that received combination of cisplatin and vitamin E compared to Sprague Dawley strain rat that received cisplatin only. Material & Methods:  Twenty four Sprague Dawley rats were divided into 4 groups randomly. Group 1 Negative Control (NC) was given an injection of 1 cc 0.9% normal saline intraperitoneally as a placebo, group 2 Positive Control (PC) was given 5 mg/kgBW cisplatin intraperitoneally, group 3 (P1) was given cisplatin injection 5 mg/kgBW intraperitoneally + vitamin E (α tocopherol) 50 mg/kgBW by gavage and group 4 (P2) was given cisplatin injection 5 mg/kgBW intraperitoneally + vitamin E (α tocopherol) 200 mg/kgBW by gavage. Vitamin E (α tocopherol) was given 3 weeks before up to 4 weeks after cisplatin injection. Observation of the germinal epithelial cells apoptosis was carried out by calculating germinal epithelial cells apoptosis in the cross-section preparations of the seminiferous tubule which gave a positive reaction to the apoptag staining, using a 400x magnification light microscope. Results: Apoptosis on positive control (PC) group was different significantly compared to the negative control (NC) group (p<0.05). There was a significant difference in the apoptosis of germinal epithelial testicular cells in the cisplatin + vitamin E 50 mg/kgBW compared to the PC group (p<0.05). The cisplatin + vitamin E 200 mg/kgBW group; had a lower number of apoptosis compared to the cisplatin + vitamin E 50 mg/kgBW (p<0.05). Conclusion: Vitamin E provides a protective effect on decreasing the amount of apoptosis due to cisplatin exposure. The protective effect of vitamin E is dose-dependent.

Aim The current study was designed to estimate the influence of Nigella sativa and Eurycoma longifolia pre-treatment and Lead acetate administration on the reproductive hormonal and spermiogram of rats. Materials and Methods: Five groups of Sprague Dawley rats have been divided into 6 rats each. Distilled water was given to Group 1 (NC) and set as the negative control. Lead acetate 20 mg/kg/day orally for one month was administered to Group 2 (PC) and set as the positive control. Group 3 (T1) were administered 20 mg/kg LA and 300 mg/kg Nigella sativa both orally/day for one month. Group 4 (T2) were received 20 mg/kg LA and 500 mg/kg Eurycoma longifolia orally/day for one month. Group 5 (T3) were administered 300 mg/kg Nigella sativa, 20 mg/kg LA, and 500 mg/kg Eurycoma longifolia orally/day for one month. Results: In this study, five groups of Sprague Dawley rats have been divided into 6 male rats each and grouped as follows; Group 1(Negative control); Group 2 (Positive control; 20mg/kg lead acetate); Group 3 (LA 20mg/kg + NS 300mg/kg); Group 4 (LA 20mg/kg + EL 500mg/kg); Group 5 (LA 20mg/kg+ NS 300mg/kg + EL 500mg/kg). All administrations were given daily for 30 days. The rats were euthanized and serum and epididymal samples were collected for reproductive hormonal assays and spermiogram determination. The estrogen concentration was less (p less than 0.05) in the EL treated group, whereas in the positive control (PC), the concentration of follicle stimulation hormones, as well as luteinizing hormones, were lower (p less than 0.05). Testosterone concentration was found to be higher (p less than 0.05) in the PC in comparison to other groups. The motility, concentration, and viability of the sperm were all low in the PC and high (p less than 0.05) in the treatment groups. The sperm abnormality was higher in the PC in compared with other groups. Conclusion: In conclusion, this study showed the preventive effect of Nigella sativa and Eurycoma longifolia administration against alterations in spermiogram and hormones caused by LA.

The aim of this study was to compare the vertical fracture resistance of roots obturated with different root canal filling materials and sealers. Crowns of 55 extracted mandibular premolar teeth were removed to provide root lengths of 13 mm. Five roots were saved as negative control group (canals unprepared and unfilled). Fifty root canals were instrumented and then five roots were saved as positive control group (canals prepared but unfilled). The remaining 45 roots were randomly divided into three experimental groups (n=15root/group) and obturated with the following procedures: in group 1, glass ionomer-based sealer and cone (ActiV GP obturation system); in group 2, bioceramic sealer and cone (EndoSequence BC obturation system); and in group 3, roots were filled with bioceramic sealer and cone (Smartpaste bio obturation system). All specimens were tested in a universal testing machine for measuring fracture resistance. For each root, the force at the time of fracture was recorded in Newtons. The statistical analysis was performed by using Kruskal-Wallis and post hoc test. There were no significant differences between the three experimental groups. The fracture values of three experimental and negative control groups were significantly higher than the positive control group. Within the limitations of this study, all materials increased the fracture resistance of instrumented roots.

Introduction: Discoloration can be caused by intrinsic or extrinsic factors. One of the discoloration treatments is teeth whitening. Teeth whitening process usually uses chemicals such as hydrogen peroxide or carbamide peroxide which can cause side effects, namely gingival irritation. Previous research has found that malic acid in strawberries can whiten teeth. Watermelons contain greater malic acid than strawberries. Objective: To analyze the  effectiveness of 100% watermelon (Citrullus lanatus) extract on teeth whitening. Methods: The study was a laboratory experimental study with a total of 15 anterior post-extraction teeth which were discolored using black tea, divided into 3 groups. Group 1 was immersed in 100% watermelon extract, group 2 was immersed in 10% carbamide peroxide as positive control and group 3 was immersed in sterile aquades as negative control, for 56 hours, measured using a shade guide and spectrophotometer. Data were analyzed using one way Anova. Results: The 100% watermelon extract was effective for teeth whitening. There was a significant difference between 100% watermelon extract compared to negative control (p < 0.05). However, there was also a significant difference between 100% watermelon extract, and 10% carbamide peroxide gel (p = 0.003). Conclusion: The watermelon extract has the ability as teeth whitening agent. However, further study is still needed to explore this result and determine the proper concentration for teeth whitening.

The possible renal and hepatic toxicities of ethylenediaminetetraacetic acid (EDTA) in bean cooking media were studied using 100 male albino mice. Two sublethal doses of EDTA were used to explore their toxic effects; 20 mg/kg and 200 mg/kg, which corresponded to 1/100th and 1/10th of LD50, respectively. Accordingly, the toxicity study was performed using 50 mice, divided into five groups ( n = 10/group) as follows: group 1 (Gp1) served as a negative control and was orally administered normal saline; group 2 (Gp2) was administered the bean cooking medium; group 3 (Gp3) was administered EDTA (200 mg/kg); group 4 (Gp4) was administered bean cooking medium containing 20 mg/kg of EDTA; and group 5 (Gp5) was administered bean cooking medium containing 200 mg/kg of EDTA. The results showed no significant changes in liver and kidney functions in Gp2 while Gp3, Gp4, and Gp5 exhibited significant increases in adverse liver and kidney function markers. Hematocrit values were significantly decreased in Gp3 and Gp5, while the total white blood cells counts were significantly decreased in Gp3 and significantly increased in Gp5. The number of platelets was decreased in Gp3, Gp4, and Gp5. The blood levels of sodium (Na+), iron (Fe2+), and calcium (Ca2+) were decreased in Gp3, Gp4, and Gp5 due to the chelating effects of EDTA. The hepatic and renal architectures were disorganized in Gp3, Gp4, and Gp5 with some hemorrhagic manifestations in livers and kidneys of mice. These results demonstrate that EDTA in bean cooking is harmful in mice under the conditions of this study, and the potentially harmful effects in humans supports restricting its use.
