Abstract
Hepatotoxicity is a common side effect of doxorubicin (Dox) treatment of cancer. Liv-52 is an ayurvedic medicine that is reported to ameliorate liver injury due to oxidative stress. We investigated the effects of Liv-52 on Dox induced oxidative damage to liver tissues of rats using biochemical and histopathological techniques. Thirty male rats were assigned randomly into three equal groups: control (CG), Dox group (DG) Liv-52 + Dox group (LD). Rats in the LD group received 50 mg/kg Liv-52 in distilled water via gastric gavage. Distilled water was given via the same route to the rats in the DG and CG groups. Rats in the LD and DG groups were injected intraperitoneally with 5 mg/kg Dox 1 h after administration of Liv-52 or distilled water. The procedure was repeated daily for 7 days. On day 8, the animals were sacrificed, and serum and tissue biochemical and histopathological assays were performed. The malondialdehyde level was increased significantly in the DG group, while glutathione and superoxide dismutase levels were significantly lower in the DG group compared to the LD and CG groups. The highest levels of alanine aminotransferase, aspartate aminotransferase and lactate dehydrogenase were found in the DG group, while the lowest levels were found in the CG group, which exhibited levels similar to those of the LD group. Treatment with Liv-52 prior to Dox treatment reduced the histopathologic changes in the Dox group. Therefore, pre-treatment with Liv-52 protected against Dox induced oxidative stress and hepatotoxicity.

Abstract
INTRODUCTION This study aimed to biochemically and histopathologically investigate the effect of sunitinib on oxidative testicular damage induced by ischemia/reperfusion in rats. MATERIAL-METHOD Experimental animals were divided into three groups of six rats each: testicular torsion-detorsion (TTD), sunitinib+testicular torsion-detorsion (STD), and sham control (SC). Sunitinib (25mg/kg) was administered orally to the STD group by gavage. Normal saline (0.9% NaCl) was administered orally to the TTD and control groups as the solvent. One hour after administration of sunitinib and 0.9% NaCl, all animal groups were done torsion-detorsion. Then, all the rats were killed by high-dose anesthesia, and their testicles were removed. Biochemical and histopathological examinations were performed on the removed testicular tissues. RESULTS Malondialdehyde; it was observed that the results in the STD group were close to those of the SC group and statistically significant lower compared to the TTD group (p=0.001). The glutathione values were statistically significantly higher in the STD group compared to the TTD group (p<0.001). Nuclear factor kappa B values, revealing a statistically significant difference between the TTD and STD groups (p<0.001). The TNF-α levels were measured and indicating that the results of the STD group were statistically significantly lower than those of the TTD group (p<0.001). Histopathologically, animal tissues given sunitinib were observed to resemble normal tissues. CONCLUSION Sunitinib was shown to prevent histopathological changes in testicular tissue against ischemia/reperfusion damage.

Abstract
OBJECTIVE We aimed at determining the protective effects of Pycnogenol on ethanol-induced retinotoxicity in an experimental model. MATERIALS AND METHODS 30 male Wistar albino rats were randomly divided into three groups: an untreated healthy control (HC group), a group in which only ethanol was daily administered for six weeks (EtOH group), and a group in which ethanol + 40 mg/kg Pycnogenol was daily administered orally for six weeks (PEtOH group). The same volume (0.5 ml) of distilled water as solvent was applied in the same manner to the rats in the HC and EtOH groups. With the rats in the PEtOH and EtOH groups, 32% ethanol at a dose of 5 g/kg was administered by oral gavage one hour after the application of pycnogenol or distilled water. At the end of the experimental period, tissue samples were obtained for biochemical examination of malondialdehyde (MDA) and total glutathione (tGSH) levels, and afterwards, the eyes were removed for histopathological examination. RESULTS Histopathological evaluations in the EtOH group showed significant destruction of retinal tissue with marked edema, decomposition and degeneration in layers, polymorphonuclear cell infiltration, dilatation and congestion in blood vessels. However, it was observed that MDA values increased and tGSH values decreased in the EtOH group. In the PEtOH group, MDA values decreased and GSH values increased. Again, degenerative changes were considerably less in this group. CONCLUSIONS In the light of biochemical markers and histopathological evaluations, it was observed that ethanol exposure caused a significant degeneration in the retinal tissue. It was found that Pycnogenol administration significantly reduced the destructive effects seen histopathologically. Biochemical results also coincided with other findings. It was concluded that ethanol-induced rethytosis can be prevented to a large extent by Pycnogenol administration.

Abstract
INTRODUCTION Cisplatin is an antineoplastic agent, which is thought to act on tissues with increased levels of reactive oxygen species and decreased levels of antioxidants. Pycnogenol is a potent antioxidant that is used in medical conditions caused by oxidative stress. The aim of our study is to demonstrate the effects of pycnogenol on cisplatin-induced uterine and ovarian damage in rats. MATERIAL AND METHODS Wistar albino female rats were randomly divided into 3 groups before the experiment as follows: a 2.5 mg/kg cisplatin group (CG; n = 10), a 40 mg/kg pycnogenol + 2.5 mg/kg cisplatin group (PCG; n = 10), and a healthy control group (HG; n = 10). Then, the ovaries and uteri of the rats were examined to determine malondialdehyde (MDA), total glutathione (tGSH) and superoxide dismutase (SOD) biochemical levels and the histopathological findings. RESULTS Our study demonstrated that, in uterine and ovarian tissues of rats administered with cisplatin, there was a decrease in the levels of tGSH and SOD, while MDA was increased; however, it was observed that these ratios were reversed in the PCG group (p < 0.05). The number of follicles in the ovarian tissues was examined in all 3 groups. When the CG group was compared with the other two groups, the number of primordial, developing and atretic follicles was low, but there was no difference in the corpus luteum count. CONCLUSIONS Pycnogenol pretreatment alleviates cisplatin-induced uterine and ovarian injury in rats because of its antioxidative effect.

Abstract
AIM In this study, it was aimed to investigate the effect of coenzyme Q10 (CoQ10) on cisplatin-induced oxidative retinal damage in rats biochemically and histopathologically. MATERIALS AND METHODS Thirty male Wistar albino rats were divided into 3 groups randomly: untreated control (C group), only 2.5 mg/kg cisplatin daily administrated group for 2 weeks (CP group), 2.5 mg/kg cisplatin + 20 mg/kg orally CoQ10 daily administrated group for 2 weeks (CoQC group). At the end of experimental period, blood samples obtained before sacrification for the biochemical examination of serum malondialdehyde (MDA), total glutathione (tGSH), total oxidant system (TOS), total antioxidant systemic (TAS) levels and after eyes were removed for examined histopathology. RESULTS As a result of our study, severe histopathological damage was detected in the retinal tissue of the cisplatin group with serum malondialdehyde (MDA) and total oxidant system (TOS) levels were high and total glutathione (tGSH) and total antioxidant systemic (TAS) levels were low. However, it was observed that the histopathological damage associated with cisplatin was decreased in the retinal tissue of the CoQ10 group, which inhibited the increase in blood serum MDA/TOS levels and decrease in tGSH/TAS levels. CONCLUSION The biochemical and histopathological results of our study were compatible with each other, so we concluded that the damage to the rat retinal tissue caused by cisplatin may be reversible with coenzyme.

Abstract
AIM To evaluate the neuroprotective effects of benidipine hydrochloride on the cerebral cortex tissues in rats exposed to cerebral ischemia-reperfusion (I/R) injury. MATERIAL AND METHODS Twenty-four male Wistar albino rats were randomly divided into three groups, and administered benidipine hydrochloride (10 ?g/kg/day) orally through a catheter for 2 h to form the study group (BIR group, n=8). The I/R procedure was performed in the rats of the IR group (n=8), and a sham group was formed to determine the normal structure of the cerebral cortex (n=8). Transient ischemia was performed by clamping the left common carotid artery for 2 h. Subsequently, reperfusion was applied for 12 h. Cerebral infarct volumes were measured and cerebral cortex tissue samples were analyzed histopathologically and biochemically by measuring malondialdehyde (MDA), total glutathione, cyclooxygenase 1 (COX-1), COX-2 and superoxide dismutase (SOD) RESULTS: The infarct area was markedly reduced in the BIR group vs. the IR group. Histopathologically, neuroprotective effects of benidipine hydrochloride were observed in the cerebral cortex tissues. The mean malondialdehyde and COX-2 levels were statistically higher in the IR group; however, in the BIR group, these levels were within the normal limits. Furthermore, the mean total glutathione, COX-1 and SOD levels were markedly lower in the IR group, and within the normal limits in the BIR group. CONCLUSION Benidipine hydrochloride may play a certain protective role in cerebral I/R injury. This effect may be related to improvement in the antioxidant capacity of brain tissue, and the inhibition of overproduction of inflammatory cytokines.

Abstract
Purpose: To examine the effect of desloratadine on kidney ischemia-reperfusion (I/R) injury in albino Wistar male rats using biochemical and histopathological methods.Methods: The treated with ischemia-reperfusion + 5 mg/kg desloratadine (IRD) group (n-6) was given 5 mg/kg desloratadine by gavage orally, and applied renal ischemia-reperfusion (BIR) group (n-6) and control (SG) group undergoing Sham operation (n-6) rats were given distilled water as solvent one hour before ketamine anesthesia. During the anesthesia period, ischemia was induced for 2 h unilaterally in the left kidney of all rats followed by reperfusion for 6 h. The kidneys of the SG group had sham operation without any intervention.Results: Our biochemical test results showed that malondialdehyde (MDA), nuclear factor kappa (NF-κB), tumor necrosis factor alpha (TNF-α), interleukin one beta (IL-1β), creatinine, and blood urea nitrogen (BUN) levels were significantly increased in the BIR group compared to the healthy control and IRD groups treated with desloratadine. Histopathological results were revealed tubular dilatation, tubular necrosis, loss of brushy margins, cast formation, and apoptotic bodies in tubular epithelial cells in the BIR group. There were no histopathological findings except for the swelling of tubule epithelial cells and the accumulation of proteinous material in some tubule lumens in renal tissue of desloratadine-treated rats.Conclusions: Experimental results suggested that desloratadine may be useful in the treatment of renal I/R injury.

Abstract
Cutaneous side effects associated with sunitinib use are a major problem in patients receiving cancer treatment. The aim of this study was to investigate the protective effect of adenosine triphosphate (ATP) against possible skin damage resulting from sunitinib use in rats. Thirty Albino Winstar rats were divided into the following three groups: healthy controls (HCs, n = 10), sunitinib (SUN, n = 10), and sunitinib + ATP (SAT, n = 10). ATP was injected intraperitoneally at a dose of 2 mg/kg. One hour subsequent to the administration of ATP and 0.9% NaCl, the SAT and SUN groups were orally administered a dose of 25 mg/kg sunitinib to the stomach. Macroscopic evaluation of the skin indicated lower levels of skin damage in the SAT group than in the SUN group. As an indicator of oxidative stress, malondialdehyde (MDA), total oxidant status (TOS), and oxidative stress index (OSI) levels were significantly higher in the SUN group than in the HC group, while total glutathione (tGSH) and total antioxidant status (TAS) levels were significantly lower. However, MDA, TOS, and OSI levels were significantly lower in the SAT group than in the SUN group, while tGSH and TAS levels were significantly higher. Histopathological examination revealed keratin plugs with edema, vasopathology, and inflammatory cell infiltration in the SUN group. The SAT group showed less necrotic epithelium, keratin plugs, edema, and vasopathology than the SUN group. ATP can be effective in preventing skin damage caused by sunitinib use by reducing oxidative stress.

Abstract
PURPOSE Acute methanol exposure leads to systemic intoxication and toxic optic neuropathy. In this experimental study, we aimed to determine the protective effects of intravenous administration of ATP in methanol-induced optic neuropathy. MATERIALS AND METHODS A total of 18 male albino Wistar rats weighing between 267 and 282 g were used for the experiment. The animals were divided into three groups as healthy control (HC), methanol (M), and methanol + ATP (M-ATP) groups. Distilled water was given to the healthy control group (n = 6) as the solvent, while 20% methanol was administered orally to the rats in M (n = 6) and M-ATP (n = 6) groups at a dose of 3 g/kg. Four hours after the administration of 20% methanol orally to the M-ATP group, ATP was injected intraperitoneally at a dose of 4 mg/kg. Eight hours after ATP injection, the animals were sacrificed by high-dose (50 mg/kg) thiopental anaesthesia and biochemical and histopathological examinations were performed on the removed optic nerve tissues. Malondialdehyde (MDA), total glutathione (tGSH), total oxidant status (TOS) and total anti-oxidant status (TAS) were analysed with biochemical tests. RESULTS MDA, TOS and OSI were significantly higher and tGSH and TAS levels were significantly lower in methanol administered group compared with the healthy controls or M-ATP group (p: 0.001). There was not any significant difference between healthy controls and M-ATP group regarding the oxidative stress parameters. There was a significant destruction and increase in thickness and astrocyte numbers and edema-vacuolization in methanol administered group compared with the healthy controls or M-ATP group (p: 0.001). CONCLUSION Intravenous ATP administration had a significant positive effect on the oxidative stress parameters and optic nerve structure in methanol-intoxicated rats. Antioxidant therapies should be considered in future studies as a possible therapy for methanol-induced toxic optic neuropathy.

Abstract
In this study, we aimed to show the effect of adenosine 5'-triphosphate (ATP) on sunitinib-induced cardiac injury in rats. The rats (n = 30) were divided equally into three groups as sunitinib group (SG), sunitinib plus ATP group (SAG), and healthy group (HG); 2 mg/kg ATP was injected intraperitoneally (ip) to the SAG group. Same volume normal saline as solvent was administered ip to the other two groups. After 1 h, 25 mg/kg sunitinib was applied orally via catheter to stomach in the SAG and SG groups. This procedure was repeated once daily for 5 weeks. At the end of this period, all animals were sacrificed and their cardiac tissue was removed. Malondialdehyde (MDA), total glutathione (tGSH), tumor necrosis factor α (TNF-α), and nuclear factor κB (NF-κB) levels in rats' cardiac tissues and troponin I (Tp-I) levels in rats' blood samples were evaluated. Histopathological analysis was also performed in cardiac tissues of the animals. MDA, TNF-α, NF-κB, and Tp-I levels were higher in the SG group compared to the SAG and HG groups (p < 0.001). tGSH levels of the SG group were lower than the SAG and HG groups (p < 0.001). The structure and morphology of cardiac muscle fibers and blood vessels were normal in the control group. In the SG group, obvious cardiac muscle tissue damage with dilated myofibers, locally atrophic myofibers, and congested blood vessels were observed. In the SAG group, marked amelioration in these findings was observed. We showed this for the first time that ATP administration exerts a protective effect against cardiac effects of sunitinib.

Abstract
We investigated using immunohistochemistry the possible protective effects of ascorbic acid, α-tocopherol and selenium during chemotherapy treatment with cyclophosphamide. Thirty female Wistar rats were divided into five groups of six: group 1, untreated control; group 2, 75 µg/kg cyclophosphamide; group 3, 75 µg/kg cyclophosphamide + 150 µg/kg/day α-tocopherol; group 4, 75 µg/kg cyclophosphamide + 200 µg/kg/day ascorbic acid and group 5, 75 µg/kg cyclophosphamide + 40 ppm/kg/day selenium. Proliferating cell nuclear antigen (PCNA) staining was used to detect cell proliferation and AT1 was used to evaluate structural damage. Caspase-8, caspase-9 and caspase-3 signal molecules were used to investigate apoptosis. In group 2, epithelium, alveolar macrophages, infiltrated lymphocytes and connective tissue were immunostained moderately to strongly with PCNA. Bronchus, alveolar wall and infiltrated lymphocytes were immunostained moderately to strongly with AT1 and diffuse strong caspase immunoreactions were observed throughout the lung tissue. AT1 and caspase immunoreactions in groups 4 and 5 were similar to group 2. In group 3, PCNA immunoreactivity was strong in the bronchiolus epithelium, endothelial cell nuclei and in stacks of infiltrated lymphocyte cell nuclei. In group 3, AT1 and caspase immunoreactions were identical to group 1. It appears that α-tocopherol inhibits lung tissue damage in rats during chemotherapy.

Abstract
BACKGROUND Methotrexate (MTX) is an antineoplastic agent, which increases the level of reactive oxygen species (ROS) and decreases the level of antioxidants. Lycopene, is a potent antioxidant, which is used because of its protective effect against tissue damage. OBJECTIVES The aim of this study was to determine the effect of lycopene on ovarian MTX-induced injury in rats. MATERIAL AND METHODS Rats (n = 36) were randomly divided into 3 equal groups: a group with MTX only (MG, n = 12), a group with lycopene and MTX (LMG, n = 12), and a healthy control group (HCG, n = 12). Then, malondialdehyde (MDA), myeloperoxidase (MPO) and total glutathione (tGSH) levels and histopathological findings were examined in the ovaries of rats. Apart from the histopathological and biochemical evaluation, the reproductive performance of the experimental groups was also examined. RESULTS Our study demonstrated that, in ovarian tissues of rats administered MTX, there was a decrease in the levels of tGSH, while MDA and MPO were increased, but it is observed that these ratios are reversed in the LMG (p < 0.05). It also has been proven that a single, high-dose use of MTX causes infertility in female rats, prolongs the gestation period and reduces the number of offspring. CONCLUSIONS Lycopene pretreatment ameliorates the MTX induced ovarian injury and infertility in rats through its antioxidative activities.

Abstract
BACKGROUND Ischemia/reperfusion (I/R) injury results from the onset of re-circulation following a perfusion deterioration period in the tissues, resulting in more damage than that caused by perfusion deterioration. This study aimed to determine the effects of pycnogenol on I/R injury in rat brain tissues. METHODS Eighteen albino Wistar rats were divided into three groups: I/R injury (IR, n = 6) group; I/R injury + pycnogenol (IR + P, n = 6) group; and sham group (SG, n = 6). After 30 min of transient ischemia, 24 h of reperfusion was achieved in the IR and IR + P groups. Surgical dissection, except for transient ischemia, was performed in SG. Next, histopathological and biochemical investigations were performed on brain tissues. Malondialdehyde (MDA), reduced glutathione (GSH), and glutathione peroxidase (GPO) were analyzed as oxidative stress markers; IL-1β and TNF-α were analyzed as inflammatory stress markers in biochemical tests. RESULTS Histopathological examination revealed normal morphology in SG and diffuse cortex damage with edema, vasopathology, and inflammatory cell infiltration in the IR group. The IR + P group showed less cortex damage, edema, and vasopathology than the IR group. The MDA, IL-1β, and TNF-α levels were significantly higher in the IR group than those in the SG group. The values of same markers for the IR + P group were significantly lower than the IR group. The GSH and GPO levels were significantly decreased with IR damage, but PYC treatment showed significant improvement in the levels. CONCLUSION This study showed that the administration of pycnogenol ameliorated brain damage after I/R injury by reducing oxidative and inflammatory damage in the rat brain.

Abstract
Purpose: Morphometric evaluation of the craniocervical region using magnetic resonance imaging method in humans and determination of the reference values that could be used in various clinics were the aims of this study. Materials and Methods: In our study, 306 (95 males and 211 females) individuals who met the necessary criteria for anatomical structure were included and taken measurements afterward. Sagittal T1- and T2-weighted images were determined as a section thickness of 3 mm, an interval of 10 mm, a matrix of 352 × 224, a field of view of 170–240 mm, and a number of excitations of 4. Measurements of anatomical structures in the craniocervical region were taken via these images. Results: Statistically significant differences were found among the findings of male and female individuals such as height of dens axis, anteroposterior distance of the dens axis (APDDA), anterosuperior distance of the dens axis (ASDDA), sagittal diameter of the foramen magnum (SDFM), total cervical vertebra length (TCVL), distance of spatium retropharyngeum, Pavlov ratio, and the ratio between sagittal diameter of canalis vertebralis (SDCV) to the APDDA. Dens axis height showed a positive correlation with ASDDA and TCVL, and a negative correlation was found between the APDDA and the spatium retropharyngeum. Conclusion: Age- and sex-related changes in the measurements of anatomical regions reveal that an increase and a decrease in the various parameters reveal that these are the normal changes presumably determined by the functional and physical demands varying on the columna vertebralis.
