Zearalenone (ZEN) is an estrogen-like mycotoxin produced by Fusarium that seriously compromises the safety of animal and human health. In this study, our aim was to evaluate the protective effect of Bacillus velezensis A2 against biochemical and pathological changes induced by zearalenone in mice. Kunming mice (n = 40; 25 ± 2 g) were allotted to four treatment groups: a control group (basic feed); a ZEN group (basic feed with a ZEN dose of 60 mg/kg); an A2 strain fermented feed group (150 g of feed mixed with 150 mL of sterile distilled water and inoculated with 5 mL of phosphate buffer salt (PBS) resuspended A2 strain); and an A2 strain fermented ZEN-contaminated feed group. (A2 strain group 150 mL pure bacterial distilled water system mixed with 150 g ZEN-contaminated feed.) Our results showed that the Bacillus velezensis A2 strain can completely degrade the ZEN-contaminated feed within 5 days. (The concentration of ZEN in fermentation was 60 μg/mL.) After the mice fed for 28 days, compared with the control group, the activities of AST and ALT were increased, the activities of glutathione peroxidase (GSH-PX) and total superoxide dismutase (T-SOD) were decreased, and the amount of creatinine (CRE), blood urea nitrogen (BUN), uric acid (UA), and malondialdehyde (MDA) in the ZEN group were increased in the mice serum (p < 0.05; p < 0.01). However, compared with the ZEN group, these biochemical levels were reversed in the A2 strain fermented feed group and in the A2 strain fermented ZEN-contaminated feed group (p < 0.05; p < 0.01). Furthermore, histopathological analysis only showed pathological changes of the mice liver in the ZEN group. The results showed that Bacillus velezensis A2 as additive could effectively remove ZEN contamination in the feed and protect the mice against the toxic damage of ZEN. In conclusion, Bacillus velezensis A2 has great potential use as a microbial feed additive to detoxify the toxicity of zearalenone in production practice.

Hepatoprotective Effects

Introduction: The present study investigated the hepatoprotective effects of stigmas, tepals and leaves of Crocus sativus on carbon tetrachloride (CCL4) induced liver injury in rats. Methods: Hydroethanolic extracts of Crocus sativus (stigmas, tepals and leaves) were administrated daily for 14 days by oral gavage. In the present study, 30 male rats divided into five groups were treated as 1: normal rats gavaged with distilled water; 2: intoxicated rats gavaged with distilled water and injected with CCL4; 3: rats treated with stigmas extract and injected with CCL4; 4: rats treated with tepal extract and injected with CCL4; 5: rats treated with leaf extract and injected with CCL4. Bodyweight and the relative liver weight were determined. Alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), total cholesterol, triglycerides, bilirubin direct and total, total protein, albumin, urea and creatinine measured in plasma. Malondialdehyde (MDA) was quantified in liver homogenate. Results: The experimental data showed that the stigmas and tepals extracts significantly prevented weight body loss and improved the relative liver weight. They significantly protected against elevation of ALT, AST, direct bilirubin, total bilirubin, LDH, ALP, creatinine and MDA. Also, they enhanced significantly total proteins and albumin compared to the CCL4 control group. Moreover, leaves reduced ALT, AST, total bilirubin, LDH and MDA significantly. Conclusion: In conclusion, these results suggest that tepals, stigmas, and leaves extracts of Crocus sativus have hepatoprotective effects on CCL4 induced liver injury in rats.

Caffeine Exposure

Prenatal caffeine exposure adversely affects the development of the reproductive organs of male rat offspring. Thus, it is conceivable that peripubertal caffeine exposure would also influence physiologic gonadal changes and function during this critical period for sexual maturation. This study investigated the impact of high doses of caffeine on the testes of prepubertal male rats. A total of 45 immature male rats were divided randomly into three groups: a control group and 2 groups fed 120 and 180 mg/kg/day of caffeine, respectively, via the stomach for 4 weeks. Caffeine caused a significant decrease in body weight gain, accompanied by proportional decreases in lean body mass and body fat. The caffeine-fed animals had smaller and lighter testes than those of the control that were accompanied by negative influences on the histologic parameters of the testes. In addition, stimulated-testosterone ex vivo production was reduced in Leydig cells retrieved from the caffeine-fed animals. Our results demonstrate that peripubertal caffeine consumption can interfere with the maturation and function of the testis, possibly by interrupting endogenous testosterone secretion and reducing the sensitivity of Leydig cells to gonadotrophic stimulation. In addition, we confirmed that pubertal administration of caffeine reduced testis growth and altered testis histomorphology.

ABSTRACT Oestradiol-17β benzoate, 120 βg, injected into five-day old male rats inhibited maturation of the seminiferous epithelium as demonstrated by histological studies performed 40–55 days post-treatment. The oestrogen treatment was ineffective when administered at the age of 20 days. The degree of testicular damage appeared to be correlated with the amount of steroid used. A dose of 240 μg of oestradiol benzoate led to severe pathological changes in almost 100 per cent of the seminiferous tubules and atrophy of the Leydig cells.

In experiments on outbred male beauty 4 months of age, the effect of the new compound ZB-16 (GPR 119 receptor agonist), with hypoglycemic activity [6], on spermatogenesis and fertilizing function was studied. Compound ZB-16 was administered intragastrically to animals of the experimental groups for 2 months (equivalent to one spermatogenesis cycle) in doses: 0,5 mg/kg (experimental therapeutic dose) and 100 mg/kg (higher dose than 200 times the therapeutic dose), the control group of males was intragastrically injected with a solvent of the compound – distilled water. It was found that under the influence of ZB-16, in males in both experimental groups, the spermatogenesis index is moderately increased (by 3,0 %, p > 0,05), the total number of spermatozoa (by 44,4 %, p > 0,05 and 19,2 %, p > 0,05, respectively, the 1st and 2nd experimental groups), the number of tubules with desquamated epithelium decreases, and the number of pathological forms of spermatozoa and the number of tubules with 12th stage of meiosis are not changed. According to the results of mating of the studied groups of males with intact females, a clear tendency towards an increase in the pregnancy index and a decrease in the post-implantation death of the embryos is revealed in the females relative to the control.

The aim of this study is to assess the effects of high blood glucose levels in male rats with diabetic induced by alloxan on their physiological conditions. Diabetes mellitus is a category of metabolic hyperglycemia disorders caused by insufficient body production or pancreatic action. In addition to hyperglycemia, a number of other factors are also important for pathogenesis, such as Hyperlipidemics and cortisol oxidative. Forty five mature male rats used in this study, these were divided into 3 groups, Control group(G1) : gavage distilled water, Group2(G2): injection intraperitoneally with Alloxan150 mg/kg bw for two weeks and Group3(G3): injection intraperitoneally with Alloxan 150mg/kg bw for twenty four days. Blood samples taken from all groups estimation of Peroxynitrate, GSH, CAT, and SOD concentrations%. The findings revealed a significant improvement in diabetic classes in glucose (p<0.05) and peroxynitrate relative to control (G1). Diabetic concentrations of (G2, G3) relative to the control group (G1) were substantially reduced in SOD, GSH, CAT and diabetes mediated (P < 0,05). In conclusion, diabetes can cause significant changes in SOD, GSH, CAT levels in rats.

Abstract Background Liver ischemia reperfusion (I/R) damage which is frequently seen in clinical hepatobiliary surgeries has no effective treatment for it. Liv-52, known to have hepatoprotective effects, is a natural antioxidant drug licensed by the Ministry of Health of India. The aim of our study is to investigate the effect of Liv-52 on liver damage induced by I/R in rats. Methods Albino Wistar male rats were divided into three groups; liver I/R (IR), 20 mg/kg Liv-52 + liver ischemia reperfusion (LIR) and sham operation applied to control group (HG). Liv-52 was administered to the LIR group (n = 6) 1 h prior to I/R application and distilled water was given orally to IR (n = 6) and HG (n = 6) groups as a solvent. Ischemia was determined as 1 h, and reperfusion was identified as 6 h in animals. Results Increased levels of alanine aminotransferase, aspartate aminotransferase and lactate dehydrogenase, malondialdehyde, myeloperoxidase, and decreased levels of superoxide dismutase, and glutathione related enzymes caused by I/R application have been converged to healthy group level with Liv-52 treatment and the damage in liver tissue has been improved histopathologically. Conclusions Liv-52 may be beneficial for preventing liver I/R damage in pre-surgery application.

Background: Visual information acquired through observation plays a pivotal role in learning a movement pattern and motor control. Objectives: This study aimed to analyze the effect of visual deprivation on learning in rats. Methods: The study sample consisted of 12 male rats, divided into three groups. Group I consisted of four rats and was considered the control group. Transection of the two optic nerves was performed on rats of group II on the seventh day after birth and group III on the seventh week after birth to develop the early blind and late blind models, respectively. A T-shaped maze device was utilized to evaluate the learning behavior of rats. Rats of groups II and III were blinded by the optic nerve surgery. In total, 20 trials per day were conducted for nine consecutive days, in which the time and number of correct arm entries were recorded. The ANOVA and Kruskal-Wallis tests were employed to analyze the results in SPSS software (version 16.0). A p-value of less than 0.05 was considered statistically significant. Results: There was a significant difference between the three groups regarding the number of correct arm entries on days one, three, and seven (P<0.05). There was also a significant difference between the three groups regarding how long it took them to enter the target box on days two and three (P<0.05). Group III had a lower number of entries to the target box and it took them a significantly longer time to enter the target box, compared to the other groups. Conclusion: According to the results, visual deprivation may affect the learning of rats during the early days; however, their learning levels increased over the following days. Moreover, the early blinded rats had a higher level of learning than the lately blinded adult rats and the same level of learning as that of the sighted adult rats.

The objective of this research was to analyze the protective effect of indole-3-carbinol against the stomach injury induced by acetylsalicylic acid. Male rats were randomly divided into eight groups of six animals in each group. Control group, OMP group, I3C group, OMP+I3C group, AA group, AA+OMP group, AA+I3C group, and AA+OMP+I3C group. The control rats were received distilled water and the experimental rats were received AA at a dose of 500 mg/kg body weight, OMP at a dose of 20 mg/kg body weight, and I3C at a dose of 50 mg/kg body weight either alone or in combination with each other, orally for seven consecutive days. Results of the present study showed ulcer protection in indole-3-cabinol treated rats was confirmed by histoarchitecture, which was comprised of the reduced size of ulcer crater and restoration of mucosal epithelium. Thus, reduced neutrophil infiltration, antiapoptotic and antioxidant action have a pivotal role in the gastroprotective effect of indole-3-carbinol.

The aim of this study was to determine the effect of tamoxifen (Tx) and its vehicle, soybean oil (SO), during the critical period of hypothalamic sexual differentiation in newborn male rats, regarding gonadal histomorphology during adulthood. The animals were randomly divided into 3 groups (n = 5 each). An hour after birth, one group was treated subcutaneously with 200 μg of Tx, using commercial SO (20 uL) as a vehicle; another group was treated with only 20 μL of SO; the control group received no treatment. All rats were weighed and sacrificed by cervical dislocation on day 90 post-treatment. Testicles were removed, weighed and processed for histological evaluation. The single administration of Tx and/or SO during the critical period of sexual differentiation of the hypothalamus permanently altered testicular histomorphology, spermatogenesis, and body weight in adulthood. Alterations included vacuolization and reduction in the number of spermatogonia and Sertoli cells. The administration of Tx reduced the testicular weight, the diameter and area of the seminiferous tubules, and the height of the germinal epithelium, and increased the intertubular space. Soybean oil by itself reduced the number of spermatocytes and spermatids more than Tx did. There was no effect on the number of Leydig cells. The possibility that soybean oil can act as an endocrine disruptor deserves greater attention and opens the possibility for the development of new methods of pest control.
