The aim of our study was to investigate parameters of oxidative/antioxidative status in rats experimentally infected with Fasciola hepatica and treated with a copper salt. The experiment was carried out on 24 male Wistar albino rats, divided into 4 groups with 6 animals in each: group 1 – healthy untreated animals, group 2 – rats orally infected with F. hepatica; group 3 – rats treated with CuSO4. 5H2O and group 4 – rats experimentally infected with F. hepatica and treated with CuSO4.5H2O. Rats from group 2 and 4 were orally infected with 15 viable F. hepatica metacercariae per animal. Rats from group 3 and 4 received CuSO4.5H2O dissolved in drinking water at a dose of 150 mg/kg body weight after post infestation week 2. Copper administration lasted 2 weeks. The rats were euthanised on the 35th day post infestation. The levels of malondialdehyde, glutathione, and the activity of Cu, Zn-superoxide dismutase and glutathione peroxidase in the liver of all rats were established. Increased liver MDA level was observed in groups infected and untreated with copper compared to control level. Reduced Cu,Zn-SOD activity was found in all infected rats as well as insignificant increase of the enzyme in group 3 compared to control group value. GPx activity was reduced in similar manner in the treated and infected groups compared to the control group. GSH level was lower in all treated rats than in controls (P<0.01). Copper liver content was increased in groups receiving CuSO4.5H2O compared both to control and infected only group. Substantial imbalance in oxidative/antioxidative status in groups 2, 3 and 4 was demonstrated compared to the control group. Combined effect of chronic copper administration and experimental F. hepatica infection increased significantly MDA level, reduced the activity of Cu,Zn-SOD and the GSH content in host livers. Elevated copper level influenced defense system in F. hepatica infected rats at a high extent. Parasites and copper acted together to increase the oxidative stress. Parasitism in the presence of copper pollution compromises the health of the host, even at low intensities.

Abstract Background: Pregabalin (PGB) used as analgesic in treatment of neurogenic pains of chronic diseases, is considered as one of the most abused anti-epileptic drugs worldwide and it has been proved that it induces addictive behaviors. The present histopathological study aimed to identify the effect of PGB administration on cerebral cortex and cerebellar cortex, in both acute and chronic toxicity. Seventy-two male and non-pregnant female adult albino rats’ 6- to 8-week-old divided into 3 main groups of 24 rats each were studied. Group 1 represented the control group and group 2 represented the acute toxicity group, in which rats were given a single dose of PGB (5000 mg/kg) orally by gavage and after 24 hours, rats were sacrificed and examined. Group 3 represented the chronic toxicity group; were given PGB 500 mg/kg orally by gavage for 12 weeks, after which rats were sacrificed and examined. Result: Cerebral cortex tissue of acute toxicity group displayed astrocytosis and dystrophic changes, while in chronic group showed degeneration, necrosis and cellular infiltrates. The cerebellum of chronic groups showed degeneration and shrunken of Purkinje cells. Conclusion: Acute and chronic intoxication with pregabalin adversely altered the structure of cerebral cortex and cerebellum.

Aluminum (Al) is present daily in our life, the long-term excessive Al intake induces neuroinflammation and cognition retardation. Annona squamosa leaves showed some medicinal activities as anti-inflammatory, antioxidant and antidiabetic drugs. This study was designed to examine the effect of ethanolic and aqueous extracts of annona squamosa leaves against aluminum chloride (AlCl3-induced neuroinflammation in rats. 40 male albino rats were randomly divided into 4 groups, 10 rats each. Group 1; (Control rats), Group 2; (rats received AlCl3 50mg/kg body weight orally (p.o), Group 3; (rats received AlCl3 and annona squamosa leave aqueous extracts (300mg/kg) and Group 4; (rats received AlCl3 and annona squamosa ethanolic extracts (300mg/kg). After two months; blood samples were collected for assessment of serum nuclear factor- ҡβ (NF-ҡβ) and Acetyl cholinesterase (Ach E). The brain of each rat was removed for assessment Brain nitric oxide, reduced glutathione (GSH), malondialdehyde (MDA), superoxide dismutase (SOD), caspase 3 and brain-derived neurotrophic factor (BDNF). AlCl3 increase brain MDA, NO, Ach E activity, NF-ҡβ and caspase 3, significant decreases in GSH, SOD activity and BDNF. Ethanolic or aqueous annona squamosa leaves extracts ameliorate MDA, NO, Ach. E activity, NF-ҡβ and caspase 3 and restore GSH, SOD activity and BDNF to near normal levels in AlCl3 treated rats. Conclusion: Both of ethanolic and aqueous annona squamosa leave extracts protect rat brain against oxidative stress and inflammation induced by AlCl3.

Abstract On a farm with permanent history of fasciolasis a study was performed aimed to know the efficacy of triclabendazole (TCBZ) and then to contrast with that of nitroxynil. Thirty-nine cattle naturally infected with Fasciola hepatica were randomly allocated into 4 experimental groups: Group 1 (control) was left untreated. Group 2 was treated with of 12 mg/kg body weight (bw) of TCBZ by oral route. Group 3 treated with 24 mg/kg bw TCBZ orally. Group 4 was treated with 10 mg/kg bw of nitroxynil subcutaneously. The anthelmintic efficacy was calculated as the percentage of reduction in faecal egg count (FEC) at 14 and 28 d post-treatment. Results indicated that there were no significant differences in the percentage of FEC reduction between control group and the groups treated with 12 or 24 mg/kg of TCBZ. On the contrary, the treatment with nitroxinyl significantly reduced the FEC and decreased the percentage of positive animals. In conclusion, Fasciola hepatica is reported for first time as resistant to TCBZ in Chile, which highlights the need of rotating drugs and assessing the efficacy of the administered drug in order to avoid the selection of resistant worms.

Background: Infection can lead to delayed wound healing. Recently it has been shown that propolis which is used in complementary medicine has an antibacterial and anti-inflammatory effect. The aim of this study is to determine whether propolis may contribute to wound healing. Material and Methods: Twenty-one male Wistar albino rats were randomly divided into three groups. Group1 and Group 2 were topically treated with propolis ointment and Thiocillin® oinment, respectively while Group 3 was the control group. On incision wound model, Thiocillin® and propolis ointments were applied on wound sites once daily for 30 days and the mean epidermal thickness (MET) at the 30th day was compared while antimicrobial activity of propolis was studied against different pathogens as well. Results: Propolis exhibited in vitro antibacterial activity against Staphylococcus aureus, Escherichia coli, Streptococcus sp. and Pseudomonas sp. It is observed that the MET in the groups of Propolis ointment and Thiocillin® ointment were significantly greater than that of the control group, while the MET in the group of propolis ointment was significantly greater than that of Thiocillin® ointment treated group. Conclusion: Propolis is effective in wound healing. Further study in-depth is necessary to probe into clinical correlation.

This study was designed to evaluate the effect of a daily dose of tramadol on selected biomarkers viz: haematological parameters, sperm count, kidney and liver damage in male albino rats. Twenty four wistar rats were divided randomly into two groups: control group and treated groups, the treated group were further divided into four groups and housed in cages. Clean drinking water was served to control (group 1), and 1.6 mg/kg bodyweight of tramadol was administered to group 2 (7 days treatment), group 3 (14 days treatment), group 4 (21 days treatment) and group 5 (21 days treatment +7 days withdrawal) in addition to a daily standard diet for all groups. Treatment of rats with tramadol caused significant decrease (P<0.05) in WBC, platelet and lymph. in group 2, on bicarbonate, AST and protein, it showed significant decrease (P<0.05) in group 3, and it showed significant decrease (P<0.05) in group 5 on Cl-, AST, ALT, bicarbonate, AST, PCV, Hb, RBC, WBC, platelet, lymphocytes and sperm count. The results indicates that tramadol has negative effects on the liver which may induce severe liver damage when used for a prolonged period, the results also shows that tramadol can cause anaemia as seen by the observed negative changes in the blood parameters evaluated. Therefore, administration should be with great caution and from a licensed pharmacist or doctor while self prescription or over the counter administration should be avoided considering the associated adverse effects.

The effect of irradiation on oxidants and antioxidants in selected tissues and a possible protective effect of curcumin on these indices were investigated. A total of 28 rats were divided into 3 groups; group 1 was control; group 2 was the irradiation group, saline was administered intraperiotenally (i.p.) for three days and then, 9 Gy gamma irradiation was applied; group 3 was the irradiation + curcumin group: curcumin was given i.p. for three days at 200 mg/kg body weight and then the same dose of irradiation was applied. A significant increase in malondialdehyde (MDA) was detected in the liver, kidney, and brain tissues of the rats as a result of irradiation (P< 0.01). Glutathione peroxidase (GSH-Px) activity in all the tissues (except for kidneys) decreased (P< 0.01), liver SOD (superoxide dismutase) activity decreased (P< 0.05), and GSH (glutathione) levels in kidney and ovary tissues (P< 0.001) significantly increased. While curcumin administration returned the increased MDA levels in the kidneys and brain in result of irradiation to normal (P< 0.01), it did not return the increased MDA levels in the liver tissue to normal (P< 0.001) despite significantly reducing them. While decreased GSH-Px and SOD activity in the liver in result of irradiation increased with the addition of curcumin (P< 0.05), increased GSH levels in the kidneys and ovaries returned to control levels (P< 0.001). When MDA values were examined, it was found that the addition of curcumin protected the liver, kidneys and brain from the oxidative damage caused by irradiation.

Pazopanib is an effective treatment for advanced renal cell carcinoma and soft tissue sarcoma. Besides classical adverse events of this drug class, hepatotoxicity has been described as a frequent side effect. The aim of the present study was to evaluate the effect of pazopanib on the liver in an experimental rat model. Sixteen Wistar albino rats were divided into 3 groups: experimental toxicity was induced with pazopanib (10 mg/kg) administered for 28 days (group 2) or 56 days (group 3) orally by gavage. Group 1 (control group) received only distilled water. Rats in groups 2 and 3 were sacrificed after the collection of blood and tissue samples on the 28th and 56th days, respectively. We found significant differences in bilirubin, alkaline phosphatase, lactate dehydrogenase, glucose, triglyceride, very-low-density lipoprotein, and iron values (p < 0.050 for all) but none in any other parameter (p > 0.050). All rats in the control group had normal histological features; however, none of the rats in groups 2 and 3 showed normal histology. In group 2, we observed mild sinusoidal dilatation, congestion, enlarged Kupffer cells, accumulation of yellow-brown-black pigment in the Kupffer cells and the accumulation of hemosiderin with Prussian blue reaction in the hepatocytes. In group 3, the findings mentioned above were more prominent, and besides these findings focal acinar transformation and macrovesicular steatosis were also observed. In group 3, mild inflammation within the portal areas was observed consisting of lymphocytes, neutrophils, and eosinophils. This study is the first that reports the biochemical and histopathological evaluation of pazopanib-related hepatic toxicity.

Objectives: Various risks have emerged in parallel to the rapidly increasing use of cell phones. Herein we studied the effects of cell phone emitted electromagnetic waves (EMW) on rat testes. Material and Methods: Twenty one adult male Albino rats were grouped into 3 groups each consisting of 7 rats. The first group was exposed to EMW on talk mode for 8 hours per day for 20 days and then their testes were extracted. The testes of the second group were extracted after 20 days of whole day EMW exposure. The third group was the control group. For the statistical analysis Mann- Whitney U analysis was performed. Results: At light microscopic examination of the testicular tissue, the existence of a high number of immature cells in the lumen of the seminiferous tubule in addition to the normal seminiferous tubules, besides irregular tubules with a reduction in the spermatogenic cell lines and tubules without lumen were observed in groups 1 and 2. Histopathological alterations were scored as 0 = none, 1 = low, 2 = medium, 3 = serious. The average scores of the three groups were found to be 4.25 ± 1.5 for the group 1, 4.33 ± 3.9 for the group 2 and 0.37 ± 1.1 for the group 3 respectively. As a result of the statistical evaluation, group 1 and group 2 had significantly higher scores than the control group (p = 0.001). Conclusion: Infertility is one of the current problems of today due to a rapid increase in its incidence and cost. The negative effects of the EMWs on the testis should be taken into account and the necessary measures should be taken for prevention.

Introduction: The aim of this experimental study was to investigate the histopathological and biochemical effects of pyrrolidine dithiocarbamate, an antioxidant and inhibitor of NF-kβ, on ischemiareperfusion injury in rats.Methods: A total of 21 male Wistar-Albino rats were randomly distributed into three groups as sham group (Group 1), ischemia-reperfusion (I/R) group (Group 2) and I/R with pyrrolidine dithiocarbamate(PDTC) group (Group 3). Left testicles of rats in Groups 2 and 3 underwent testicular torsion of 720° for four hours and 100 mg/kg of PDTC was administered intraperitoneally prior to detorsion in Group 3. An hour after detorsion process, left orchiectomies were performed and 5 ml of intracardiac blood samples were drawn from rats in all three groups. Histopathological examination of testis tissues performed and measurement of superoxide dismutase (SOD) and malondialdehyde (MDA) levels in blood samples were taken.Results: Elevated levels of MDA and decreased SOD activity, together with decreased Johnson tubular biopsy scores consistent with I/R injury were observed in Group 2 (p<0.05). Group 1 and Group 3 were similar in terms of MDA levels, SOD activity, and Johnson scores (p>0.05).Conclusions: Our results indicated that PDTC may have beneficial effects for alleviation of I/R injury in testicular tissue in rats. Understanding the underlying mechanisms and exploration of its diagnostic and therapeutic potential requires further randomized, controlled trials on a larger scale.
