The experiment was conducted to investigate the protective effect of Petroselinum crispum leave extracted against gentamicin-induced nephrotoxicity in male rabbits by studying the body weight, clinical signs, haematological and biochemical parameters, gross lesion and histopathological changes. Twenty four rabbits male were used and divided into 4 groups. Group 1: rabbits served as a negative control, received distilled water 1 ml(orally). Group 2: rabbits served as a positive control group, received gentamicin at a dose of 80 mg/kg/day intramuscular for 15 days. Group 3: rabbits received gentamicin at a dose of 80 mg/kg/day then after one hour treated with ethanolic extract of Petroselinum crispum at dose 125 mg/kg orally for 15 days. Group 4: rabbits received gentamicin at a dose of 80 mg/kg/day then after one hour treated with ethanolic extract of Petroselinum crispum at dose 250 mg/kg orally for 15 days.The results of the gentamicin treated group( positive control group) showed clinical signs such as loss of body weight, loss of appetite and rough hair with hematuria. The body weight a significantly declined (p≤ 0.05) compared other groups. There was a significant decrease (p≤ 0.05) in WBC count, lymphocyte, GSH, SOD, CAT, and GPX levels, while it recorded a significant increase (p≤0.05) in weights of the kidneys, neutrophils, creatinine, urea, and MDA. Histological studies showed several kidney pathological changes such as pale colour, enlargement in size and weight and easy from detaching as opposed to negative control group. On the other hand, the group treated with ethanolic extractof Petroselinum crispum at dose 125 mg/kg induced improved of parameters as recorded significant increased(P ≤ 0.05) in body weight, WBC count, lymphocyte, GSH, SOD, CAT, and GPX, while significant decreased (P ≤ 0.05) in weights of the kidneys, neutrophils, creatinine, urea, and MDA compared with the positive control group whereas rabbits treated with ethanolic extract of Petroselinum crispum at dose 250 mg/kg restored the parameters and histological changes of the kidney to near normal status compared with the negative control group. These results showed that the dose-detected Petroselinum crispum extract (250mg / kg) acts as potential curative effect against gentamicin-induced nephrotoxicity in male rabbits.

Metolachlor and currently its biological active isomer S–metolachlor is one of the most widely used herbicides in the world. Chronic experiments in rats have found hepatocarcinogenic effect of metolachlor, and epidemiological studies have found positive relationship between enzyme exposure to metolachlor and prevalence of liver cancer. Possibility of the influence of harmful impurities contained in technical products on the detected effects is emphasized. Objective is to study promotor effect of S–metolachlor generics with different hepatotoxicity in carcinogenesis of liver in rats induced by nitrosodiethylamine (NDEA) and analyse possibility of its realisation in human. Materials and Methods. Experiments were performed in male Wistar Han rats on hepatocarcinogenesis model “NDEA — hepatectomy”. Two specimens of S–metolachlor generics were studied; and their ratio of S/R enantiomers was 87/13 % with different hepatotoxicity. Substances were administered intragastrically in the doses of 1.5,15 and 150 mg/kg body weight for 8 weeks. Animals of the negative control group received water, and positive control — phenobarbital. Promotor effect was evaluated by the standardised parameters of the total area and number of hepatocyte foci expressing γ-glutamyl transpeptidase (GTP). Results. No clinical signs of the toxic action of S–metolachlor on the rat body induced to carcinogenesis by NDEA were found. Increase in the number and total area of γ-GTP positive foci in the liver of animals on tumorogenic dose of both specimens of S–metolachlor as well as phenobarbital was found. Mean area of focus in the liver of rats on more toxic specimen was lower. The threshold of promotor action of S–metolachlor on hepatocarcinogenesis has been established at the level of γ 15 mg/kg body weight. Analysis of literature data on the mechanism of hepatotoxic action of metolachlor allowed to make a conclusion aboutphenobarbital-like mechanism of promotor action that is realised through constitutive androstane receptor (CAR). This mechanism is species-specific for rodents; therefore, the results of epidemiological studies on the possibility of liver cancer in human cannot be confirmed experimentally. Conclusion. Tumorogenic dose of S–metolachlor generics with different degree of hepatotoxicity shows promotor effect in NDEA induced carcinogenesis in rat liver. Hepatotoxicity of S–metolachlor inhibits growth of γ-GTP positive foci. The threshold of hepatocarcinogenesis promotion has been established at the level of γ 15 mg/kg body weight. The mechanism of the observed effect is not relevant for human. Key Words: S–metolachlor, hepatocarcinogenesis initiated by nitrosodiethylamine, Wistar Han rats, γ-glutamyltranspeptidase.

Ermawati EF, Samigun, Hadjanti ES. 2011. The antipyretic effect of bitter melon (Momordica charantia) leaf in male white mice. Biofarmasi 9: 7-11. The potential of antipyretic effect of flavonoid in bitter melon (Momordica charantia L.) leaf is one of the traditional medicines that people used. This research aimed to determine the antipyretic effect of the extract of bitter melon leaf in male white mice. This experimental research was arranged as a post-test only controlled group design. Thirty Wistar furrow white mice with 2 months of ages and 100 gram in body weight were used as an animal model. Those mice were grouped equally into five groups, consisted of negative control group (2 ml water), positive control group (6.3 mg paracetamol/100 g body weight of mice/2 ml water), the first dose of the extract of bitter melon leaf (0.756 mg/100 g body weight of mice/2 ml water), the second dose of extract (1.512 mg/100 g body weight mice/2 ml water) and the third dose of extract (2.268 mg/100 g body weight mice/2 ml water). The measurement of mice temperature was conducted before and 2 hours after treated by DPT vaccine, and every 30 minutes post-treatment until 180 minutes. The result of this research was analyzed by using Anova statistical test and post-hoc test. The result of Anova statistical test showed significant differences among groups of variance, but there was no significant difference among times of variance. The result of posthoc test showed the significant differences between negative control group, positive control group and the extract of bitter melon leaf group. This research concluded that there was an antipyretic effect in the extract of bitter melon leaf in male white mice, but the effect was lower than paracetamol effect.

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.

Dental procedures produce a large amount of spatter and aerosols that create concern for the transmission of airborne diseases, such as Covid-19. This study established a methodology with the objective of evaluating new associated strategies to reduce the risk of cross-transmission in a health environment by simulating spread of potentially contaminated dispersion particles (PCDP) in the environment. This crossover study, was conducted in a school clinic environment (4 clinics containing 12 dental chairs each). As a positive control group (without barriers), 12 professionals activated at the same time the turbine of dental drill, for one minute, with a bacterial solution (Lactobacillus casei Shirota, 1.5x108 CFU/mL), which had been added in the cooling reservoir of the dental equipment. In the experimental groups, the professionals made use of; a) an individual biosafety barrier in dentistry (IBBD) which consists of a metal support covered by a disposable PVC film barrier; b) a Mobile Unit of Disinfection by Ultraviolet-C, consisting of 8 UV lamps-C of 95W, of 304μW/cm2 of irradiance each, connected for 15 minutes (UV-C) and; c) the association between the two methods (IBBD + UV-C). In each clinic, 56 Petri dishes containing MRS agar were positioned on the lamps, benches and on the floor. In addition, plates were placed prior to each test (negative control group) and plates were also placed in the corridor that connects the four clinics. In the groups without barrier and IBBD + UV-C the passive air microorganisms in Petri dishes was also evaluated at times of 30, 60, 90 and 120 minutes after the end of the dental’s drill activation. The mean (standard deviation) of CFU of L. casei Shirota for the positive control group was 3905 (1521), while in the experimental groups the mean using the IBBD was 940 (466) CFU, establishing a reduction on average, of 75% (p<0.0001). For the UV-C group, the mean was 260 (309) CFU and the association of the use of IBBD + UV-C promoted an overall average count of 152 (257) CFU, establishing a reduction on average of 93% and 96%, respectively (p<0.0001). Considering these results and the study model used, the individual biosafety barrier associated with UV-C technology showed to be efficient strategies to reduce the dispersion of bioaerosols generated in an environment with high rate of PCDP generation and may be an alternative for the improvement of biosafety in different healthy environment.

  The niacin in energy drinks has metabolic product that cause oxidative stress and liver damage, while the liver damage can be prevented by hepatoprotective agents. Scoparone in Artemisia vulgaris L. can act as a hepatoprotector by its antioxidant effect. This study aimed to investigate the effectivity of Artemisia vulgaris L. extract as a hepatoprotector in wistar hepatocytes induced by niacin. This study used 25 male rats which were divided into 5 groups: normal, the negative control, the positive control, the treatment group I, and II. Treatment was conducted for 28 days. The samples were terminated and the hepatocyte were prepared for histological examination. Histological appearance was catagorized as mild, moderate, and severe damage with or without inflamatory cells activity. The data analysis by Kruskal Wallis showed significant difference (p<0,001). Further analysis by Mann Whitney revealed significantly difference (p<0,05) between normal group and all groups, negative control group and positive control group, and positive control group and treatment group I, but not significantly difference between negative control group and treatment group I, negative control group and treatment group II, positive control group and treatment group II, and between treatment groups. The study concluded that the effectivity of Artemisia vulgaris L. extract has not been proven as a hepatoprotector but further study is needed to draw a definite conclusion.   Keywords: energy drink, niacin, Artemisia vulgaris L., hepatoprotector

Objective: Matrix metalloproteinases (MMPs) exist in human saliva and dentin and play an important role in the degradation of organic matrix in teeth. Chemically modified tetracycline-3 (CMT-3) is an inhibitor of MMPs. CMT-3 has been used experimentally to treat caries since 1999, but no distinction between dental caries prevalence and dentin caries prevalence has been described. Methods: A total of 65 Sprague-Dawley rats were randomly divided into three groups. The positive control group (25 rats) was inoculated with Streptococcus mutans (ATCC700610) and fed the cariogenic feed of improved Keyes Diet 2000. The CMT-3 group (25 rats) was also inoculated with S. mutans and fed the cariogenic feed of improved Keyes Diet 2000; the surfaces of rats’ molars were daily treated with 0.02% CMT-3. The negative control group (15 rats) was only fed the standard rodent chow. At the end of the 10th week, the dental caries prevalence and dentin caries prevalence of each group were calculated, and the regions of caries were assessed. Results: No caries was found in the negative control group. The dental caries prevalence of the CMT-3 and the positive control group was 75.0 and 83.3%, respectively (p > 0.05, Table 2). The dentin caries prevalence of the CMT-3 and the positive control group was 33.3 and 70.8%, respectively (p < 0.05, Table 2). The Keyes scoring of dentin caries in the CMT-3 group was significantly lower than that in the positive control group (p < 0.05, Table 3). Conclusions: CMT-3 had no effect on the prevalence of dental caries, but could lower the prevalence and slow down the progression of dentin caries.

Curcumin has remarkable anti-inflammatory and antioxidant properties. The aim of this study was to investigate the protective effects of curcumin on a rat model of carbapenem-resistant Escherichia coli–induced acute lung injury (ALI). Thirty-two rats were randomly allocated to 4 groups to induce an ALI: negative control group (rats not infected with E coli with no antibiotic treatment), positive control group (rats infected with E coli with no antibiotic treatment), imipenem group (rats infected with E coli that received intraperitoneal injection of imipenem), and the imipenem+curcumin group (rats infected with E coli that received intraperitoneal injection of imipenem and were fed on curcumin).The rats were killed, and lung tissues samples were harvested for biochemical analyses and histopathologic examination. Total antioxidant status (TAS), total oxidant status (TOS), tumor necrosis factor α (TNFα), and interleukin-6 (IL6) were measured. TOS increased in the positive control group (P &lt; 0.001) and decreased in the imipenem and imipenem+curcumin groups (P &lt; 0.001 and P &lt; 0.001, respectively). TAS decreased in the positive control group (P = 0.005). Imipenem treatment did not increase TAS, but the imipenem+curcumin group increased TAS (P = 0.014). TNFα and IL6 increased in the positive control group compared with the negative control group (P &lt; 0.001 and P = 0.010, respectively). Imipenem decreased TNFα (P &lt; 0.001), but did not decrease IL6 (P = 0.418). Imipenem+curcumin decreased TNFα (P &lt; 0.001); this decrease was more pronounced compared with the imipenem group (P = 0.008). IL6 decreased in the curcumin group compared with the positive control group (P = 0.011). Curcumin combined with imipenem can be an alternative therapeutic agent to overcome the resistance of E coli strains.
