The effect of boldenone anabolic steroid, and endurance and resistance training on liver damage markers in rats

Background: This study aimed at investigating the effect of boldenone, and endurance and resistance training on liver damage in rats. Materials and Methods: In this study, 70 male Wistar rats aged 12 weeks (weight, 228±7 g) were randomly divided into 10 equal groups: control, sham, boldenone (2 mg/kg), boldenone (5 mg/kg), resistance training, resistance training-boldenone (2 mg/kg), resistance training-boldenone (5 mg/kg), endurance training, endurance training-boldenone (2 mg/kg) and endurance training-boldenone (5 mg/kg) groups. The resistance training program included an 8-week climb from the ladder, three times a week and each session 3 sets with 5 repetitions and the endurance training program was 8-week running on treadmills, 3 days a week, every day 30 minutes at a speed of 12 meters per minute. The injection was performed in the biceps femoris muscle once a week. After anesthesia, autopsy was performed and the liver tissue was isolated for histological studies. Results: The most liver tissue damage was observed in the boldenone group without training; so that the vacuolar degeneration more than 66 and the presence of 1-3 necrotic cells was very important. In resistance training and high-dose boldenone resistance training, liver damage was also observed as vacuolar degeneration. In the endurance training-boldenone inflammation group, increased kupffer cells and mild vacuolar degeneration were observed. Histological studies showed that endurance training reduced the vacuolar degeneration and inflammation and did not increase kupffer cells. Conclusion: It seems that boldenone can cause damage to liver and endurance training compared with resistance training may cause more reduction in liver damage, especially reduction in the vacuolar degeneration and inflammation induced by boldenone

Structural changes of cardiac tissue in response to boldenone supplementation with or without alcoholic extract of jujuba fruit during resistance training in male Wistar rats

Background: Abuse of anabolic androgenic steroids has been linked to a variety of different cardiovascular side effects. The use of medicinal herbs has been shown to reduce disease and cardiovascular disorders. This study aimed at examining the structural changes of the cardiac tissue in response to boldenone supplementation along with the alcoholic extract of jujuba during resistance training in male Wistar rats. Materials and Methods: In this experimental study, 30 male Wistar rats aged 8-12 weeks (weight 202±9.34 g) were randomly divided into five groups: control, boldenone, extract of iujuba+boldenone, boldenone+resistance training and boldenone+resistance training+extract of jujuba. The resistance training program included climbing the ladder for 8 weeks, 3 days a week, 1 session training in a day and each session consisted of the 3 sets and 5 repetitions. Injection was conducted in depth in the hamstring once a week, on an appointed day. After anesthesia, autopsy was performed and the cardiac tissue was isolated. Results: The results showed that boldenone caused tissue damage, hyperemia, abnormal cytoplasm and unclear and dispersed nuclei. In the boldenone+resistance training group, the heart tissue had high levels of hyperemia and the muscle cells were a little abnormal. In the boldenone+jujube group, appearance of the tissue was normal and a restorative effect was evident in the tissue. Conclusion: It seems that boldenone can cause structural damage to the heart tissue and the resistance training along with the jujube extract can reduce some of the cardiovascular disorders (necrosis and inflammation) caused by the use of anabolic steroids

Biosynthesis of gold nanoparticles by two bacterial and fungal strains, Bacillus cereus and Fusarium oxysporum , and assessment and comparison of their nanotoxicity in vitro by direct and indirect assays

Background: Although nanoparticles (NPs) have many advantages, it has been proved that they may be absorbed by and have toxic effects on the human body. Recent research has tried to evaluate and compare the nanotoxicity of gold nanoparticles (AuNPs) produced by two types of microorganisms in vitro by two different methods. AuNPs were produced by Bacillus cereus and Fusarium oxysporum, and their production was confirmed by visible spectral, transmission electron microscope, and X-ray diffraction (XRD) analyses. The human fibroblast cell line CIRC-HLF was treated with AuNPs, and the induced nanotoxicity was measured using direct microscopic and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays. Results: The results showed that the produced AuNPs had a maximum absorbance peak around 510\u2013530 nanometer (nm), with spherical, hexagonal, and octagonal shapes and average sizes around 20\u201350 nm. The XRD results confirmed the presence of GNPs in the microbial culture supernatants. An MTT assay showed that GNPs had dose-dependent toxic effects, and microscopic analysis showed that GNPs induced cell abnormalities in doses lower than the determined half-maximal inhibitory concentrations (IC50s). Conclusions: In conclusion, the biologically produced AuNPs had toxic effects in the cell culture, and direct techniques such as microscopic evaluation instead of indirect methods such as MTT assay were more useful for assessing the nanotoxicity of the biologically produced AuNPs. Thus, the use of only MTT assay for nanotoxicity evaluation of AuNPs is not desirable

Comparing of the effects of sesame oil and rapeseed oil versus suet oil and animal butter on the reproductive system of male rats

Background The aim of this study was to compare the effect of vegetable oils and animal oils on the reproductive system of male rats. Methods This study was a random and observational study conducted on 36 male rats with the age of 6 weeks weighing 200 ± 20 grams. Different groups were fed by sesame oil, suet oil, rapeseed oil and animal butter. The control group was fed by standard food used normally to feed animals in the laboratories. At the end of six weeks, testosterone level changes and weight changes were compared among different groups. Data were analyzed by SPSS-IBM version 16. Result Weight changes among groups did not show a dramatic statistical difference (P = .571 > 0.005). Average weight in control group was 202 and about the male rats fed by 10% of animal butter and by sesame oil were 206.5 and 99, respectively. Weight changes among groups were significant (P value = 0.005 > 0.0004). The average testosterone level in the control group was 2.4. This value in the different groups fed by 10% oils, the maximum was 12.2 and the minimum was 1.35 assigned to animal butter and rapeseed oil, respectively. So we concluded that using 10% of different oils causes an increase in testosterone level (P value = 0.001 > 0.05). The maximum testosterone level was 3.6 in the rapeseed 20% group and lowest 0.45 in the sesame 20% group. Conclusion We found that animal oil-containing diet has no significant harmful effect on male rat reproductive system in comparison with plant oils

Assessment of Gold Nanoparticles Cytotoxicity Produced by the Biological Method by Fusarium Oxysporum on Normal and Cancerous Fibroblast Cell Lines

Background and Aims: Although there are several ways of nanoparticles production, however the biological method of nanoparticles production is under attention of researchers due to its eco friendly and energy saving properties. In the present study biosynthesis of gold nanoparticle was done by Fusarium oxysporum fungus strain and the cytotoxicity of the obtained nanoparticles was evaluated in the cell culture. Materials and Methods: Fusarium oxysporum was purchased and cultured in Sabouraud dextrose broth medium. The culture supernatant was subjected to chloroauric acid solution at the final concentration of 1 mM. After nanoparticles production, the color changed reaction mixture was used for characterization with spectrophotometry, XRD and TEM microscopy. The obtained nanoparticles were washed and sterilized. Finally two cell lines (CIRC-HLF as normal and SW 872 as cancerous cell lines) were used for 3-(4,5 dimethyl thiazol-2yl)-2,5 diphenyl tetrazolium bromide (MTT) assay. Results: The fungal supernatant color after 24 hours was changed from yellow to red. TEM images have shown the nanoparticles were spherical or hexagonal and their sizes were around 50-70 nanometer. MTT assay and cell culture assay showed that the produced GNPs had toxic effect when they were used at high concentrations and the CIRC-HLF cell line was more resistant than SW 872 one against the higher concentration of GNPs. Conclusions: It seems that the biological production of gold nanoparticles by Fusarium oxysporum can be done and  can be easily produced, washed, sterilized and can be used in vivo

Comparison between the Nature and Activity of Silver Nanoparticles Produced by Active and Inactive Fungal Biomass Forms on Cervical Cancer Cells

Silver nanoparticles (SNPs) can be produced by active and inactive forms of biomass, but their properties have not been compared. Recent research is attempting to reveal their differences in shape, size, amount, antibacterial activity, cytotoxicity, and apoptosis induction. The biomass of Fusarium oxysporum was divided into four groups and pretreated in the following devices: room temperature (RT) and refrigerator (for preparation of active biomass forms), autoclave, and hot air oven (for preparation of inactive biomass forms). Samples were floated in ddH2O, and SNPs were produced after the addition of 0.1699 g/L AgNO3 in the ddH2O solution. SNP production was confirmed by visible spectrophotometry, transmission electron microscopy (TEM) and X-ray diffraction (XRD). SNPs were washed, and their concentration was determined by measuring atomic emission spectroscopy with inductively coupled plasma (ICP-OES). For antibacterial activity, the plate-well diffusion method was used. MTT and Annexin V-FITC/propidium iodide assays were used for cytotoxicity and apoptosis induction, respectively. The maximum absorbance peaks for SNPs pretreated in RT, refrigerator, autoclave, and hot air oven were 404, 402, 412, and 412 nm, respectively. The SNPs produced were almost the same shape and size, and the XRD results confirmed the presence of SNPs in all samples. Due to the differences in the type of bacterial strains used, the SNPs produced showed some differences in their antibacterial activity. The MTT assay showed that the amounts of SNPs in their IC50 dose based on the results of ICP-OES were 0.40, 0.45, 0.66, and 0.44 ppm for the samples pretreated in the hot air oven, autoclave, and refrigerator, and RT, respectively. The apoptosis induction results showed that the biologically engineered SNPs induced more apoptosis (about 34.25%) and less necrosis (about 13.25%). In conclusion, the type and activity of SNPs produced by the active and inactive forms of fungal biomass did not change. Therefore, use of the inactive form of biomass in the future to avoid environmental contamination is reccommended
