Objective: Cobalt nanoparticles (NPs), especially cobalt oxide NPs (Co3O4 NPs) are attracting unique shaped NPs that are used in different biomedical applications and medicine. Different in vitro studies report their toxic and carcinogenic effect but limited in vivo studies were present on its genotoxic potential. The present study was aimed to evaluate the genotoxic potential of Co3O4 NPs on bone marrow cells and sperms and the protective role of omega-3 in male albino mice.Methods: Animals were segregated into four groups that were orally treated for 3 consecutive days, Group 1: Negative control; Group 2: Omega-3 (250 mg/kg); Group 3: Co3O4 NPs (20 mg/kg); and Group 4: Combined group (250 mg/kg Omega-3 and Co3O4 NPs 20 mg/kg).Results: The present results show that Co3O4 NPs administration significantly increased number of micronucleated polychromatic erythrocytes (PCEs)/1000 PCEs, sperm abnormalities, and DNA damage, significantly decreased sperm motility and concentration in comparison to negative control group. However, Omega-3 administration in the combined group modulates the genotoxic potential of Co3O4 NPs in comparison to Co3O4 NPs group.Conclusion: The present study reports the genotoxic potential of Co3O4 NPs in vivo and assesses the protective role of Omega-3 administration due to its antioxidant effect.

<p>Fish oil has been studied for medicinal purposes, including its antipyretic properties. Eel (<em>Anguilla bicolor bicolor</em>) oil, which contains vitamins and fatty acids, including Omega-3 (EPA and DHA), is also expected to have the antipyretic effect. This research aimed to examine the antipyretic activity of eel oil on white mice (<em>Mus musculus</em> L.). An in-vivo study was done on thirty Swiss-Webster strain males mice that previously got 20% yeast-induced fever. Six treatments were applied including normal group (untreated), a negative control group (yeast-treated), a positive control group treated with acetaminophen (1.764 mg/20 g body weight), and three groups treated with eel oil (0.048, 0.096 and 0.192 g/20 g body weight, respectively). The data was analyzed statistically using one way ANOVA then was continued with LSD post hoc test. The results showed that eel oil has significantly reduced yeast-induced hyperthermia on mice five hours after application at doses 0.096 and 0.192 g/20 g body weight. Our finding suggests that eel oil possess antipyretic properties when was applied in certain doses, and this effect is presumably attributed to its high content of fatty acid, including EPA and DHA.</p>

The methanol extracts from the underground and aerial part of the two species of Gentiana genus, Gentiana asclepiadea L. and Gentiana cruciata L. from Serbia, were investigated for their antigenotoxic activity against wellestablished mutagenic agent ethyl methanesulfonate (EMS) using the in vivo sexlinked recessive lethal (SLRL) test on Drosophila melanogaster. For this purpose, three days old Canton S males were treated with the potent mutagen EMS in concentration of 0.75 ppm, alone and combined with methanol extracts obtained from underground or aerial part of G. asclepiadea and G. cruciata in concentration of 5%, separately. Although EMS in concentration of 0.75 ppm increased the mutation frequency in all three broods, post-treatments with methanol extracts obtained from the underground and aerial part of G. asclepiadea and G. cruciata in concentration of 5%, respectively, drastically reduced the frequency of sex-linked recessive lethal mutations induced by EMS. Compared to the sucrose, as a negative control, methanol extract obtained from underground part of G. cruciata showed the most potent antigenotoxic activity. Extracts from the underground and aerial part of the two species of Gentiana genus, G. asclepiadea L. and G. cruciata L. from Serbia used in our experiments showed a clear antimutagenic effect, reducing the frequency of mutations induced by a strong mutagen such as EMS.

Abstract Background: This research was performed to synthesize nanophytosomes-loaded high phenolic fraction (HPF) from Juniperus polycarpos fruit extract and investigate its antiproliferation effects against breast cancer in mice model. Results: The nanophytosomes-loaded HPF from Juniperus polycarpos fruit extract was synthesized. The mice trial was conducted to determine the possible toxic effects of the synthesized nanophytosomes. The anticancer, pro-apoptotic, and antioxidative activities of the nanophytosomes were determined. The nanophytosomes-loaded HPF had a spherical structure with a size of 176 nm and a polydispersity index coefficient of 0.24. The in-vivo study manifested that nanophytosomes-loaded HPF significantly improved weight gain and food intake compared to the negative control group (p<0.05). The nanophytosomes-loaded HPF significantly enhanced the expression of bax (3.4-fold) and caspase-3 (2.7-fold) genes but reduced bcl2 (3.6-fold) gene expression in tumor cells. The average tumor size was significantly decreased in mice treated with nanophytosomes-loaded HPF (p<0.05). The expression of GPX (2.3-fold) and SOD (2.7-fold) antioxidants in the liver of mice supplemented with nanophytosomes-loaded HPF was significantly developed compared to the negative control (p<0.05). The nanophytosomes-loaded HPF did not show toxicity on normal cells. Conclusion: Our results indicated that nanophytosomes-loaded HPF might be a potential anticancer agent for the breast cancer treatment.

Background: Genotoxicity screening of drugs is essential. It is mandatory for new drugs. However, screening of drugs already in use is also necessary. Several cephalosporins are reported to induce chromosomal aberrations in previous studies. But there is paucity of data regarding the genotoxic potential of ceftriaxone. Hence the present study was undertaken to evaluate the genotoxic potential of ceftriaxone, a third generation cephalosporin, by micronucleus assay in albino mice.Methods: In vivo micronucleus test was performed with mice bone marrow after intraperitoneal injection of ceftriaxone at 100mg/kg BW and 200mg/kg BW at 24 hr and 48 hr harvest time. Mice bone marrow was harvested, and slides were prepared. The percentage of micronucleated polychromatic erythrocytes (% MnPCE) and the ratio of polychromatic erythrocytes to normochromatic erythrocytes (PCE:NCE) were determined. The data from ceftriaxone treated groups was compared with control group and analyzed using ANOVA followed by Dunnett's test.Results: Ceftriaxone at the dose of 100mg/kg BW and 200mg/kg BW did not exhibit any significant increase in the percentage of micronucleated polychromatic erythrocytes. It also did not decrease the ratio of polychromatic erythrocytes to normochromatic erythrocytes significantly.Conclusions: The present study demonstrates that ceftriaxone is not genotoxic in in vivo micronucleus study in albino mice at a dose of 100mg/kg BW and 200mg/kg BW.

Staphylococcus aureus infection causes oxidative stress in neutrophils. The immune cells use reactive oxygen species (ROS) for carrying out their normal functions while an excess amount of ROS can attack cellular components that lead to cell damage. The present study was aimed to test the protective role of nanoconjugated vancomycin against vancomycin-sensitive Staphylococcus aureus (VSSA) and vancomycin-resistant Staphylococcus aureus (VRSA) infection induced oxidative stress in neutrophils. VSSA- and VRSA-infection were developed in Swiss mice by intraperitoneal injection of 5×106 CFU/mL bacterial solutions. Nanoconjugated vancomycin was treated to VSSA- and VRSA-infected mice at its effective dose for 10 days. Vancomycin was treated to VSSA and VRSA infected mice at similar dose, respectively, for 10 days. The result reveals that in vivo VSSA and VRSA infection significantly increases the level of lipid peroxidation, protein oxidation, oxidized glutathione level, and nitrite generation and decreases the level of reduced glutathione, antioxidant enzyme status, and glutathione-dependent enzymes as compared to control group; which were increased or decreased significantly near to normal in nanoconjugated vancomycin-treated group. These finding suggests the potential use and beneficial protective role of nanoconjugated vancomycin against VSSA and VRSA infection induced oxidative imbalance in neutrophils.

WISP1, as a member of the CCN4 protein family, has cell protective effects of promoting cell proliferation and inhibiting cell apoptosis. Although some studies have confirmed that WISP1 is concerned with colon cancer and lung cancer, there is little report about the influence of WISP1 in traumatic brain injury. Here, we found that the expression of WISP1 mRNA and protein decreased at 3 d and then increased at 5 d after traumatic brain injury (TBI). Meanwhile, immunofluorescence demonstrated that there was little colocation of WISP1 with GFAP, Iba1, and WISP1 colocalized with NeuN partly. WISP1 colocalized with LC3, but there was little of colocation about WISP1 with cleaved caspase-3. Subsequent study displayed that the expression ofβ-catenin protein was identical to that of WISP1 after TBI. WISP1 was mainly located in cytoplasm of PC12 or SHSY5Y cells. Compared with the negative control group, WISP1 expression reduced obviously in SHSY5Y cells transfected with WISP1 si-RNA. CCK-8 assay showed that pyrroloquinoline quinone (PQQ) had little influence on viability of PC12 and SHSY5Y cells. These results suggested that WISP1 played a protective role after traumatic brain injury in rats, and this effect might be relative to autophagy caused by traumatic brain injury.

Abstract Doxorubicin is a chemotherapeutic agent known to cause cardiotoxicity that is thought to be associated with oxidative stress. The aim of the current study is to investigate the role of grape polyphenols’ antioxidant property as cardioprotective against doxorubicin-induced cardiotoxicity. Adult Wistar rats weighing 200 ± 20 g were divided into 3 different groups: a doxorubicin group that received a single intraperitoneal administration of doxorubicin (8.0 mg/kg body weight), an experimental group that received doxorubicin and grape polyphenol concentrate (25 mg/kg) via intragastric route, and the third group was a negative control group that received water only. On day 8, blood samples and tissues were harvested for analyses. The results indicated that grape polyphenol concentrate was able to reduce the signs of cardiotoxicity of doxorubicin through the reduction of aspartate aminotransferase activation, increasing the plasma antioxidant levels and decreasing the level of free radicals. The results also showed that grape polyphenol concentrate was able to reverse doxorubicin-induced microscopic myocardial damage. The myocardial protective effect of grape polyphenol might likely be due to the increase in the level and activity of the antioxidant enzymes, superoxide dismutase, catalase, and glutathione peroxidase. In conclusion, grape polyphenol concentrate displayed cardioprotective effect and was able to reverse doxorubicin-induced-cardiomyopathy in experimental rats.
