Abstract
Hypoxic-ischemic encephalopathy (HIE) is a cause of serious morbidity and mortality in newborns. Dexpanthenol, which is metabolized into D-pantothenic acid, has antioxidant and other potentially therapeutic properties. We examined some effects of dexpanthenol on the brains of week-old rat pups with HIE induced by obstruction of the right carotid artery followed by keeping in 8% O2 for 2 hours. Dexpanthenol (500 mg/kg) was administered intraperitoneally to 16 of 32 pups with HIE. Protein, DNA, and lipid oxidation degradation products were assayed and hippocampal and cortical cell apoptosis and neuronal cell numbers were evaluated in stained sections. Dexpanthenol application reduced oxidative stress and inflammation. TNF-α and IL-6 cytokine levels in HIE also decreased with dexpanthenol treatment. The numbers of caspase-3 positive cells in the dentate gyrus and CA1/CA2/CA3 regions of the hippocampus was lower, and apoptosis was decreased in the dexpanthenol-treated animals. These findings suggest possible clinical applications of dexpanthenol in human HIE.

Abstract
Parkinson's disease (PD) is the second most common and progressive neurodegenerative disease. This experimental study was designed to investigate the neuroprotective effects of dexpanthenol on antioxidant and anti-inflammatory processes in a rotenone-induced Parkinson's disease model in rats. Twenty-one male rats were randomly divided into 2 groups. The rotenone group (n = 14) was administered rotenone by intrastriatal injection, and the vehicle group (n = 7) was administered DMSO with the same application route. All animals underwent rotational movement testing with apomorphine injection 10 days later. Those with Parkinson's disease model were randomly divided into 2 groups. While 1 ml/kg of saline was applied to the saline group (n = 7), 500 mg/kg was administered to the dexpanthenol group intraperitoneally for 28 days. After 28 days, all rats were euthanized and brain tissue was removed. While striatal areas were evaluated immunohistochemically, brain MDA, TNF-α, and HVA levels were measured to evaluate their anti-oxidative and anti-inflammatory effects. In the dexpanthenol group, the total count (p < 0.001) and intensity (p < 0.001) of dopaminergic neurons in the striatal areas increased compared to the saline group. It was revealed that MDA (nmol/g) (p < 0.001) and TNF-α (pg/g) (p < 0.001) levels decreased in the dexpanthenol group, while HVA (ng/mg) levels increased (p < 0.01). This study suggests that dexpanthenol may have a neuroprotective effect by reducing neuronal loss, oxidative damage, and neuroinflammation in the striatum in rats.

Abstract
Trauma-induced primary damage is followed by secondary damage, exacerbating traumatic brain injury (TBI). Dexpanthenol has been shown to protect tissues against oxidative damage in various inflammation models. This study aimed to investigate possible antioxidant and neuroprotective effects of dexpanthenol in TBI. Wistar albino male rats were randomly assigned to control (n = 16), trauma (n = 16) and dexpanthenol (500 mg/kg; n = 14) groups. TBI was induced under anesthesia by dropping a 300 g weight from 70-cm height onto the skulls of the rats. Twenty-four hours after the trauma, the rats were decapitated and myeloperoxidase (MPO) levels, luminol- and lucigenin-enhanced chemiluminescence (CL), malondialdehyde (MDA) levels, superoxide dismutase (SOD) levels, and catalase (CAT) and caspase-3 activities were measured in brain tissues. Following transcardiac paraformaldehyde perfusion, histopathological damage was graded on hematoxylin-eosin-stained brain tissues. In the trauma group, MPO level, caspase-3 activity and luminol-lucigenin CL levels were elevated (p < 0.05-0.001) when compared to controls; meanwhile in the dexpanthenol group these increases were not seen (p < 0.05-0.001) and MDA levels were decreased (p < 0.05). Decreased SOD and CAT activities (p < 0.01) in the vehicle-treated TBI group were increased above control levels in the dexpanthenol group (p < 0.05-0.001). in the dexpanthenol group there was relatively less neuronal damage observed microscopically in the cortices after TBI. Dexpanthenol reduced oxidative damage, suppressed apoptosis by stimulating antioxidant systems and alleviated brain damage caused by TBI. Further experimental and clinical investigations are needed to confirm that dexpanthenol can be administered in the early stages of TBI.

Abstract
OBJECTIVE Dexpanthenol (DXP) reportedly protects tissues against oxidative damage in various inflammation models. This study aimed to evaluate its effects on oxidative stress, inflammation, apoptosis, and neurological recovery in an experimental rabbit spinal cord ischemia/reperfusion injury (SCIRI) model. METHODS Rabbits were randomized into 5 groups of 8 animals each: group 1 (control), group 2 (ischemia), group 3 (vehicle), group 4 (methylprednisolone, 30 mg/kg), and group 5 (DXP, 500 mg/kg). The control group underwent laparotomy only, whereas other groups were subjected to spinal cord ischemia by aortic occlusion (just caudal to the 2 renal arteries) for 20 min. After 24 h, a modified Tarlov scale was employed to record neurological examination results. Malondialdehyde and caspase-3 levels and catalase and myeloperoxidase activities were analyzed in tissue and serum samples. Xanthine oxidase activity was measured in the serum. Histopathological and ultrastructural evaluations were also performed in the spinal cord. RESULTS After SCIRI, serum and tissue malondialdehyde and caspase-3 levels and myeloperoxidase and serum xanthine oxidase activities were increased (P < 0.05-0.001). However, serum and tissue catalase activity decreased significantly (P < 0.001). DXP treatment was associated with lower malondialdehyde and caspase-3 levels and reduced myeloperoxidase and xanthine oxidase activities but increased catalase activity (P < 0.05-0.001). Furthermore, DXP was associated with better histopathological, ultrastructural, and neurological outcome scores. CONCLUSIONS This study was the first to evaluate antioxidant, anti-inflammatory, antiapoptotic, and neuroprotective effects of DXP on SCIRI. Further experimental and clinical investigations are warranted to confirm that DXP can be administered to treat SCIRI.

Abstract
We investigated the nephroprotective effect of D-panthenol in rhabdomyolysis-induced acute kidney injury (AKI). Adult male Wistar rats were injected with 50% glycerol solution to induce rhabdomyolysis. Animals with rhabdomyolysis were injected with D-panthenol (200 mg/kg) for 7 days. On day 8, we examined AKI markers, renal histology, antioxidant capacity, and protein glutathionylation in kidneys to uncover mechanisms of D-panthenol effects. Rhabdomyolysis kidneys were shown to have pathomorphological alterations (mononuclear infiltration, dilatation of tubules, and hyaline casts in Henle's loops and collecting ducts). Activities of skeletal muscle damage markers (creatine kinase and lactate dehydrogenase) increased, myoglobinuria was observed, and creatinine, BUN, and pantetheinase activity in serum and urine rose. Signs of oxidative stress in the kidney tissue of rhabdomyolysis rats, increased levels of lipid peroxidation products, and activities of antioxidant enzymes (SOD, catalase, and glutathione peroxidase) were all alleviated by administration of D-panthenol. Its application improved kidney morphology and decreased AKI markers. Mechanisms of D-panthenol's beneficial effects were associated with an increase in total coenzyme A levels, activity of Krebs cycle enzymes, and attenuation of protein glutathionylation. D-Panthenol protects kidneys from rhabdomyolysis-induced AKI through antioxidant effects, normalization of mitochondrial metabolism, and modulation of glutathione-dependent signaling.

Abstract
Background: Atopic dermatitis (AD) is an inflammatory skin disease of multiple phenotypes and endotypes, and is highly prevalent in children. Many people of all ages, including active adolescents, pregnant women, and the elderly, suffer from AD, experiencing chronicity, flares, and unexpected relapse. Dexpanthenol has multiple pharmacological effects and has been employed to treat various skin disorders such as AD. We aimed to summarize the up-to-date evidence relating to dexpanthenol and to provide a consensus on how to use dexpanthenol effectively for the treatment of AD. Methods: The evidence to date on the application and efficacy of dexpanthenol in AD was reviewed. The literature search focused on dexpanthenol use and the improvement of skin barrier function, the prevention of acute flares, and its topical corticosteroid (TCS) sparing effects. Evidence and recommendations for special groups such as pregnant women, and the effects of dexpanthenol and emollient plus in maintenance therapy, were also summarized. Results: Dexpanthenol is effective and well-tolerated for the treatment of AD. Dexpanthenol improves skin barrier function, reduces acute and frequent flares, has a significant TCS sparing effect, and enhances wound healing for skin lesions. Conclusion: This review article provides helpful advice for clinicians and patients on the proper maintenance treatment of AD. Dexpanthenol, as an active ingredient in ointments or emollients, is suitable for the treatment and maintenance of AD. This paper will guide dermatologists and clinicians to consider dexpanthenol as a treatment option for mild to moderate AD.

Abstract
Sepsis is capable of causing systemic infections resulting in multiple organ damage. Dexpanthenol (DXP) has been reported to protect against kidney and liver injury. Therefore, this paper attempts to explore the role of DXP in sepsis-induced kidney and liver injury. A mice model of sepsis was established using the cecal ligation and puncture (CLP) method. The expressions of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6 and monocyte chemoattractant protein (MCP)-1 in the serum of mice were measured utilizing enzyme linked immunosorbent assay (ELISA). Additionally, the damage of kidney and liver tissues in CLP-induced mice was determined by their respective commercial kits, western blot, and hematoxylin–eosin (HE) staining kits. The apoptosis of kidney and liver tissues in CLP-induced mice was assessed by means of terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) and western blot. It was observed that DXP decreased the expressions of TNF-α, IL-1β, IL-6, and MCP-1 in the serum of CLP-induced mice, attenuated the functional impairment, pathological damage, inflammation, and cell apoptosis of kidney tissue. Meanwhile, DXP decreased the functional impairment of liver in CLP-induced mice, reduced the levels of inflammatory factors and antioxidant enzymes, attenuated liver pathological damage, and decreased cell apoptosis in liver tissues. In conclusion, DXP attenuates inflammatory damage and apoptosis in kidney and liver organs in a sepsis model.

Abstract
Objective Ischemia/reperfusion (I/R) may cause irreversible damage to tissues and organs. We evaluated the effects of dexketoprofen on a renal I/R model in rats. Methods The study included 30 male rats. Control group received 1 mL of saline. Dexketoprofen group received 1 mL (25 mg) of dexketoprofen intraperitoneally. After 60 minutes renal ischemia, 23 hours reperfusion was applied. In Sham group, laparotomy was performed with a medial line incision without any additional procedure. Changes in the plasma malondialdehyde (MDA), renal tissue MDA, plasma glutathione peroxidase (GPx), superoxide dismutase (SOD), catalase (CAT), BUN, creatinine and albumin levels, and histopathological changes were evaluated. Results CAT values were significantly lower in Control as compared with the Sham group. Plasma levels of MDA in the Control group were significantly higher than in the Dexketoprofen group. BUN and creatinine values were significantly higher in the Dexketoprofen group. The severity of tissue injury in the Dexketoprofen group was significantly higher than in Control and Sham groups Conclusion Although dexketoprofen reduces the I/R-induced systemic inflammation, it increases renal tissue damage.

Abstract
INTRODUCTION Testis torsion is a urological emergency and a serious situation that may cause testis atrophy, testicular dysfunction and infertility due to ischaemia/reperfusion(I/R) injury even with early intervention. OBJECTIVE To assess the protective effect of dexpanthenol administered intratesticular after detorsion against testis I/R injury. STUDY DESIGN Twenty-seven rats were randomly divided into 3 groups containing 9 rats each. The 1st group comprised the sham group with no procedure performed. The 2nd group had only torsion applied, while the 3rd group had torsion + dexpanthenol applied. Rats had 720° clockwise rotation applied to the left testis. After 2 h of ischaemia, testes were de-torsioned and the dexpanthenol group had 500 mg/kg dexpanthenol administered intratesticular after detorsion. After 4 h of reperfusion, rats had blood samples taken and orchiectomy was performed for histologic assessment. RESULTS A significant difference was detected in all parameters [necrosis(p:<0.001), Cosentino grade (p < 0.001), congestion (p:0.005), fibrosis (p:<0.001), interstitial oedema (p:0.017), JTBS score (p:<0.001), apoptosis (p < 0.001) and testosterone levels (p:0.006)] when the sham, torsion, and torsion + dexpanthenol groups were compared. Significant differences were observed for fibrosis (p:0.010), Cosentino score (p < 0.001), JTBS score (p:<0.001), apoptosis (p:0.001) and total testosterone levels (p:0.013) when torsion and torsion + dexpanthenol groups were compared. The torsion + dexpanthenol group was identified to have more preservation of testis function observed histologically and hormonally compared to the torsion group. DISCUSSION Dexpanthenol is used in many areas due to both epithelizing and antioxidant effects and lack of clear side effects. In spite of use of many chemical and biological agents to protect against testis I/R injury, none have entered routine use. This study showed that dexpanthenol, which can be easily injected intratesticular during detorsion surgery, has protective effect against histological and functional injury that may develop linked to testis I/R injury. The main limitations of the study are short duration of follow-up due to being a rat experiment and lack of comparison of lipid peroxidation products. CONCLUSION This study identified that dexpanthenol with clinically easy use by intratesticular injection after detorsion during surgery had a protective effect against histological and functional injury that will develop linked to I/R injury in the testis.

Abstract
AIM Although the most common age-related neurodegenerative disease defined by memory loss is Alzheimer's disease (AD), only symptomatic therapies are present. A complex pathway for the AD pathogenesis that includes an increase in inflammation has recently been suggested. Since in previous animal experiments dexpanthenol has anti-inflammatory and neuroprotective activities, effects and role of dexpanthenol in an intracerebroventricular (ICV)-streptozotocin (STZ) induced sporadic-AD(memory impairment) animal model have been examined. DESIGN AND METHODS In total, 18 adult sprague-dawley rats were classified into 3 groups; control (n = 6), STZ + Saline (n = 6) and STZ + Dexpanthenol (n = 6). Twelve AD-induced rats through STZ-injection (3 mg/kg) into both lateral ventricles via stereotaxy were separated into two groups five days after STZ administration: one of these groups was treated with dexpanthenol (1000 mg/kg/day, i.p.) for 3 weeks and the other with saline. A passive avoidance learning (PAL) test was used after treatment, followed by brain tissue extraction in all subjects. Brain levels of tumor necrosis factor-alpha (TNF-α) and choline acetyl transferase (ChAT) were measured and Cresyl violet staining was used to count neurons in cornu ammonis-1 (CA1) and cornu ammonis-3 (CA3). RESULTS It was observed that ICV-STZ significantly shortened PAL latency, increased levels of TNF-α in brain, decreased activity of ChAT in brain, and number of hippocampal neurons. However, dexpanthenol significantly reduced all of those STZ-induced harmful effects. CONCLUSION Dexpanthenol significantly prevented the memory deficit induced by ICV-STZ through mitigating neuronal loss in hippocampus, cholinergic deficiency and neuroinflammation in rats. These findings suggest that dexpanthenol may be beneficial for treating memory impairment.

Abstract
Cisplatin (CIS) is an antineoplastic agent used for treating solid organ tumors. Toxic side effects of CIS treatment include nephrotoxicity, neurotoxicity, ototoxicity, myelosuppression and hepatotoxicity. Dexpanthenol (DEX) exhibits antioxidant and anti-inflammatory effects and protective effects against free oxygen radicals. We investigated the protective effects of DEX on CIS induced nephrotoxicity. Animals were divided into four groups of 10. The control group was given saline. The DEX group was treated with DEX for 10 days. The CIS group was treated with a single dose of CIS. The DEX + CIS group was given a single dose of CIS followed by DEX for 10 days. We found increased levels of malondialdehyde (MDA), blood urea nitrogen (BUN) and creatinine, while superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and myeloperoxidase (MPO) levels were decreased in the CIS group. MDA, BUN and creatinine levels were decreased, while SOD, CAT, GPx and MPO levels were increased in the DEX + CIS group. Renal tubule damage, inflammation and histopathology scores were significantly higher in the CIS group than the control. The DEX + CIS group exhibited less renal tubule damage and inflammation, and lower histopathological assessment scores than the CIS group. Significant cortical tubule damage and interstitial inflammation were observed in the CIS group. Tubule damage was slightly less, and mild tubule dilation and less cast formation were observed in the DEX + CIS group; also, inflammation was less severe than for the CIS group. DEX may have therapeutic potential for treating CIS induced nephrotoxicity due to its antioxidant and anti-inflammatory properties.

Abstract
Objective: The aim of this study was to evaluate histopathological, functional and bone densitometry examinations of the beneficial effects of dexpanthenol (DEX) on nerve regeneration in a rat model of peripheral nerve crush injury.Methods: Thirty adult Sprague-Dawley rats were divided equally into three groups. A crush injury was simulated in all rats by clamping the right sciatic nerve for one minute. In group 1, one day before the surgical procedure, 500 mg/kg DEX administered via intraperitoneally (ip) was initiated and continued three times in a week during the experiment period as 28 days. In group 2, rats received a dose of 10 mg/kg DEX to investigate possible effects of DEX alone. Group 3 served as the control (sciatic nerve injury) and was not given any drugs.Results: Performance was significantly lower in group 3 compared to the drug treatment groups during the rotarod test (30 rpm and 40 rpm) (p < 0.05). After a while, the rats which were able to remain on the rod was significantly lower in group 3 during the acceleration test (p < 0.05). Hot plate latency test results in group 3 were significantly lower when compared to the other groups (p < 0.05).Conclusion: DEX appears to be useful as a supportive clinical agent for the treatment of pain and nerve damage.

Abstract
Cecal ligation and puncture (CLP) is a commonly used model of sepsis in vivo. We investigated the effects of dexpanthenol (DXP) on heart, lung and aorta in CLP-induced sepsis in rats. Rats were divided into four groups of eight: group 1, sham (SH); group 2 (DXP), 500 mg/kg DXP injected intraperitoneally (i.p.); group 3 (CLP), CLP performed; group 4 (CLP + DXP), 500 mg/kg DXP injected i.p. after CLP. Heart, lung and aorta specimens were harvested for histopathological and biochemical analysis. Heart rate increased in group 3 compared to group 1; DXP administration to group 4 did not alleviate this change. In heart tissue samples, MDA levels were decreased significantly in groups 2 and 4 compared to group 3. The levels of GSH in groups 2 and 3 were elevated compared to groups 1 and 2. SOD activity was increased significantly in group 4 compared to group 3. CAT activity for group 4 was increased significantly compared to groups 1 and 3. We found that caspase-9 and caspase-3 activity was increased after application of CLP. Also, DXP treatment decreased the number of caspase-positive cells significantly compared to group 3. DXP appears to be promising for reducing sepsis-related mortality.

Abstract
Varicocele is a common cause of male infertility. It is reported that low sperm concentration, motility and morphology are indicative of increased sperm DNA fragmentation index (DFI) in men with varicocele. Although research has been conducted into the relationship between varicocele and DFI, little is known about seminal oxidation-reduction potential (ORP) in varicocele patients. We assessed the relationship between varicocele with seminal ORP and sperm DFI in both fertile and infertile men. This prospective case-control study compared the findings from infertile men with varicocele to those of men with normal spermatogenesis without varicocele. Semen samples were collected and assessed using the WHO (2010) guidelines. ORP was measured (mV) and normalized to sperm concentration (mV/106 sperm/mL). DFI was measured using the sperm chromatin structure assay (SCSA) method. For group comparisons, only samples with a concentration >1 × 106 sperm/mL were included. Infertile men with varicocele had significantly lower mean sperm concentration, motility and total sperm count. Conversely, infertile men with varicocele had a significantly higher mean serum FSH level, and higher ORP and DFI values than fertile controls. ORP was higher in patients with varicocele and positively correlated with DFI (p < 0.01). ORP and DFI showed significant negative correlations with semen parameters (sperm concentration, motility and total sperm count) in infertile men with a varicocele.

Abstract
PURPOSE Contrast-induced nephropathy (CIN) is one of the side effects of diagnostic procedures. Oxidative stress plays an important role in CIN's pathophysiology. Dexpanthenol (Dexp) is a substance with antioxidant efficacy. We investigated the likely protective effects of dexpanthenol for CIN. METHODS Twenty-four Sprague-Dawley rats were divided randomly into four groups of 6 rats; control (group 1), Dexp (group 2), CIN (group 3) and Dexp + CIN (group 4). All rats were restricted of water moderately to facilitate of nephrotoxicity. Dexp was administered into the intraperitoneally at a dose of 500 mg/kg for 5 days in groups 2 and 4. The same amount of saline was applied via intraperitoneally to group 1 and 3. In CIN and Dexp + CIN groups, L-NAME (10 mg/kg), tenoxicam (0.5 mg/kg) and sodium amidotrizoate (10 ml/kg) were administered on the 4th day via the tail vein for CIN. All rats were euthanized on the 6th day and samples for biochemical and pathological evaluations were collected. RESULTS When the Dexp + CIN group and the CIN group were compared, it was found to be provide a significant decline at the level of acute tubular injury and necrosis in kidney biopsies by dexp. Furthermore Dexp significantly reduced the serum cystatin C (Cys-C) levels, not serum creatinine. There was no statistically significant difference between the groups in total oxidant and antioxidant levels. CONCLUSIONS Dexpanthenol did not have significant effect on oxidative stress of acute kidney injury on this rat model. However, it has ameliorated serum Cys-C levels and histopathological findings of CIN.

Abstract
Hyperglycemia increases reactive oxygen species (ROS) and the resulting oxidative stress contributes to the development of diabetic complications. Dexpanthenol (Dxp) is the biological active form of pantothenic acid. We investigated whether Dxp administration could decrease oxidative stress as a way to treat renal complications of diabetes mellitus (DM). Thirty-two male Wistar albino rats were divided into four groups: control, Dxp, DM and DM + Dxp. Experimental diabetes was induced by a single dose of streptozotocin (STZ). After administration of STZ, the DM + Dxp group was administered 500 mg/kg Dxp intraperitoneally every day for 6 weeks. At the end of the study, blood glucose levels were measured and rats were sacrificed. Kidneys were embedded in paraffin, sectioned and stained with hematoxylin and eosin, and periodic acid-Schiff. The mean malondialdehyde levels, glutathione peroxidase, superoxide dismutase and catalase activities, and total antioxidant and total oxidant status also were measured. The control group was normal in histological appearance. We observed congestion, inflammation, glomerulosclerosis, tubular desquamation, loss of villi and hydropic degeneration in tubule cells in the DM group. Indicators of oxidative stress were elevated and antioxidant activity was reduced in the DM group compared to controls. In the DM + Dxp group, oxidative stress was decreased, antioxidant activity was increased and histopathological changes were reduced compared to the DM group. We found that Dxp exhibited ameliorative effects on STZ induced diabetic nephropathy by increasing antioxidant activity.

Abstract
Nasal blockage is the most bothersome symptom of acute rhinitis. Nasal decongestant sprays containing alpha-sympathomimetics, such as oxymetazoline and xylometazoline, have a rapid onset of action. However, this effect decreases with repeated application and, furthermore, the ciliary function of the nasal mucosa is practically paralyzed. Dexpanthenol promotes cell proliferation and protects the epithelium. Combining these two agents has demonstrated beneficial synergetic effects on the symptoms of acute rhinitis. In a post hoc analysis of a large-scale double-blind, active-controlled study including 152 patients, we could demonstrate that the benefit of added dexpanthenol appears as early as on the third day of the combined application of xylometazoline and dexpanthenol in terms of complete or near-to-complete freedom from symptoms. After 5 days, 47% of the patients were cured under the combined treatment compared with only 1% under xylometazoline monotherapy. These data show that the addition of dexpanthenol to an alpha-sympathomimetic nasal spray not only improves its tolerability but also further increases its effectiveness and leads to expedited cure.

Abstract
BACKGROUND Amikacin has the largest spectrum among aminoglycosides, its nephrotoxic effect limits its utilization. Our purpose in this study is to review the protective effect of dexpanthenol against the nephrotoxic effect of amikacin, accompanied with histopathological and biochemical parameters. METHODS 32 rats were randomly separated into four groups with eight in each (amikacin (1.2mg/kg/day), amikacin (1.2mg/kg/day)+dexpanthenol (500mg/kg/day), dexpanthenol (500mg/kg/day) and control). In order to assess the oxidative balance and renal damage between groups, biochemical parameters (total antioxidant capacity (TAS), total oxidant stress (TOS), catalase (CAT), paraoxonase (PON), arylesterase (ARES), urea, and creatinin) were studied from the blood samples. At the end of the 14th day, renal tissues were reviewed blindly by a pathologist. RESULTS TOS and oxidative stress index (OSI) values were significantly lower in the group which was administered with dexpanthenol+amikacin compared to the group which only received amikacin (respectively, p=0.001, p=0.002). Antioxidant biochemical parameters (TAS, CAT, PON, and ARES) were significantly higher in the group which was administered with dexpanthenol+amikacin compared to the group administered only with amikacin (respectively, p=0.007, p=0.001, p=0.003, p=0.003). Urea and creatitin values were found to be significantly lower in the group which was administered with dexpanthenol+amikacin compared to the group administered only with amikacin (respectively, p=0.002, p=0.001). Histopathologic changes such as glomerular and tubular epithelium changes and interstitial edema were clearly observed in the group administered only with amikacin, such findings were insignificant in the group administered with dexpanthenol+amikacin. CONCLUSION It was revealed with biochemical and histopathologic data that nephrotoxic effects created by amikacin administration can be limited with dexpanthenol by using them together, and further advanced clinical studies are required.

Abstract
OBJECTIVE Dexpanthenol (Dxp), antioxidant and anti-inflammatory agent, plays an important role in the repair systems against oxidative stress and inflammatory response. The objective of this study is to determine the effect of Dxp on experimental endometriosis model. STUDY DESIGN A prospective experimental study was conducted in Experimental Animal Laboratory of Mustafa Kemal University, Hatay. Twenty nonpregnant female Wistar albino rats, in which experimental model of endometriosis was surgically induced, were randomly divided into 2 groups. Group 1 was administered 500 mg/kg/d Dxp intraperitoneally for 14 days, and group 2 was given the same amount of saline solution. After 2 weeks of medication, the rats were killed and implant volumes, histopathologic scores; and levels of serum total antioxidant status, total oxidant status (TOS), and oxidative stress index (OSI) were evaluated. Plasma and peritoneal fluid levels of tumor necrosis factor α (TNF-α) were analyzed. RESULTS The endometriotic implant volumes, histopathologic scores, and serum TOS and OSI values were significantly decreased ( P < .05) in the Dxp group compared to the control group. Plasma and peritoneal fluid TNF-α levels were significantly decreased ( P < .05) in the Dxp group compared to the control group. CONCLUSION Dexpanthenol has free radical scavenger effects, and antioxidant properties has significantly regressed endometriotic implant volumes, histopathologic scores, and serum TOS and OSI values. Serum and peritoneal fluid TNF-α levels were significantly decreased in the Dxp group. So Dxp decreased oxidative stress.

Abstract
AIM The aim of this study was to show the preventative effects of dexpanthenol in radiation injuries caused by radiotherapy (RT) through the use of lung perfusion scintigraphy in the pre-RT and post-RT periods. MATERIALS AND METHODS Six male New Zealand rabbits (5-6 months of age and ∼2.5-3 kg in weight) were the used in this study. The animals were subjected to Tc-macroaggregated albumin lung perfusion scintigraphy in the pre-RT and post-RT (i.e. 2 weeks after treatment) periods. The scintigraphies were performed with the same dose by the same staff and the methodology used the same acquisition parameters. The rabbits were divided into two groups: group I (administered RT only) and group II (also administered intramuscular 500 mg dexpanthenol injections for 14 consecutive days after RT). Quantification was performed to compare the groups and the quantification variables were compared using a paired samples t-test, with P value less than 0.05 considered to be statistically significant. Histopathological analysis was also carried out. RESULTS The post-RT scintigraphies indicated a decrease in the counts in both lungs, suggesting early post-RT injury. The difference between the counts obtained from both lungs in groups I and II was significantly different and favoured group II. Histopathological results confirmed the scintigraphy results. CONCLUSION It is possible to estimate post-RT changes in the early period (in contrast to previous data) by lung perfusion scintigraphy. Dexpanthenol may also reduce the effects of RT to a degree. Although this is the first study to report the preventive effects of dexpanthenol on RT injuries, further studies are warranted in this area.

Abstract
Free iron leads to the formation of pro-oxidant reactive oxygen species (ROS). Humic acids (HAs) enhance permeability of cellular wall and act as a chelator through electron transferring. This study was designed to test chelator effect of HA on iron as well as its anti-oxidant effect against the iron-induced hepatotoxicity and cardiotoxicity. The rats used were randomly divided into four groups (n = 8/group): group I (the control group); group II (the HA group), humic acid (562 mg/kg) was given over 10 days by oral gavage; group III (the iron group), iron III hydroxide polymaltose (250 mg/kg) was given over 10 days by intraperitoneal route; and group IV (the HA plus iron group), received the iron (similar to group II) plus humic acid (similar to those in groups II and III) group. Blood and two tissue samples both from liver and heart were obtained for biochemical and histopathological evaluations. Iron deposition, the iron-induced hepatotoxicity, and cardiotoxicity were demonstrated by histopathological and biochemical manner. However, no significant differences were observed in the serum biochemical values and the histopathological results among the iron and the HA plus iron groups in the liver tissue but not in the heart tissue. The protective effects of humic acid against iron-induced cardiotoxicity were shown but not against hepatotoxicity in our study.

Abstract
BACKGROUND/PURPOSE In pathogenesis of necrotizing enterocolitis (NEC), both oxidative stress and inflammation are considerable risk factors. The study was designed to evaluate whether administration of dexpanthenol (Dxp) is able to attenuate intestinal injury through the antioxidant and antiinflammatory mechanisms in a neonatal rat model of NEC. METHODS Forty newborn pups divided into four groups were included in the study: control, control+Dxp, NEC, and NEC+Dxp. NEC was induced by hyperosmolar formula and additionally the pups were exposed to hypoxia/hyperoxia and cold stress. They were sacrificed on postnatal day four, and their intestinal tissues were analyzed biochemically and histopathologically. RESULTS Dxp caused a significant decrease in intestinal damage as determined by the histological score, villus height and number of goblet cells in NEC groups (p<0.0001). Tissue malondialdehyde, total oxidant status, and oxidative stress indexes levels were higher in the NEC group than in the control and control+Dxp groups (p<0.001). These values were reduced in the pups treated with Dxp (p≤0.004). Superoxide dismutase, glutathione peroxidase, and reduced glutathione activities were significantly reduced in the NEC group compared to the others (p<0.005). Treatment with Dxp significantly reduced elevations in tissue homogenate levels of tumor necrosis factor-α and interleukin-1β in the NEC+Dxp group (p=0.002 and p=0.01, respectively). CONCLUSIONS Dexpanthenol seems to have antiinflammatory and antioxidant properties. Prophylaxis with Dxp has a potential to reduce the severity of intestinal damage in NEC in the animals.

Abstract
BACKGROUND We investigated the anti-inflammatory and protective effects of concomitant use of dexpanthenol (DXP) and N-acetylcysteine (NAC) induced ischemia/reperfusion (I/R) injury of kidney. METHODS Forty rats were randomly divided into 5 groups. In all groups except for Group 1(Sham), renal arteries bilaterally occluded with vascular clamp for IR injury. Group 1(Sham), received a single dose of 10 mL/kg isotonic saline daily by intraperitoneal (IP) injection for three days. Group 2(IR), received a single dose of 10 mL/kg isotonic saline daily by IP injection for three days. Group 3(IR + NAC), received 300 mg/kg NAC daily by IP injection for three days. Group 4(IR + DXP), received 500 mg/kg DXP daily by IP injection for three days. Group 5(IR + NAC + DXP), received 500 mg/kg DXP and 300 mg/kg NAC daily by IP injection for three days. Serum urea (BUN), creatinine (Cr) and neutrophil gelatinase-associated lipocalin (NGAL, lipocalin 2, siderocalin) levels were measured as kidney function tests. TNF-α levels were measured as inflammatory marker. Tissue sections were evaluated histopathologically under light microscopy. RESULTS IR + NAC + DXP group received both NAC and DXP before induction of renal I/R and as the biochemical and histopathological data revealed the results of the IR + NAC + DXP group and sham group were similar. Biochemically and histopathologically, combined use of NAC and DXP has better results when each of them used alone. CONCLUSION We concluded that concomitant use of DXP and NAC plays a major role against I/R injury and may be useful in acute treatment of I/R induced renal failure.

Abstract
This experimental study was designed to investigate the protective effects of molsidomine (MOL) on against cisplatin-induced ototoxicity (CIO). To examine this effect, distortion product otoacoustic emissions (DPOAEs) measurements and serum levels of oxidative and antioxidant status [including malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), glutathione peroxidase (GPX), total oxidant status (TOS), total antioxidant status (TAS), and oxidative stress index (OSI)] were evaluated. Thirty-two female wistar albino rats were divided into four groups including; control (Group K), cisplatin (Group C), cisplatin plus MOL group (Group CM), and MOL group (Group M). DPOAEs measurements between 0.9961 and 8.0003 Hz as DP-gram and input/output (I/O) functions were performed in the same (left) ear of all rats on days 0, 1st, 5th and 12th. Prior to death, the last DPOAEs measurements and blood samples were taken. In the C group, statistically significant DPOAE amplitude reductions were detected at 2.5195, 3.1758, 3.9961, 5.0391, 6.3516 and 8.0039 Hz frequencies (p < 0.05) between 0th and 1st, 0th and 5th and 0th and 12th days' measurements (p < 0.05). Serum level of MDA, TAC and OSI levels were significantly higher in the C group versus K group (p < 0.05). In the CM group, there were no significant differences at all frequencies between 0th and other days' measurements (p > 0.05) and the serum levels of all biochemical parameters were shifted toward normal values, similar to the K group (p < 0.05). No significant differences were detected in the either M or K group's measurements. According to these results, cisplatin-related ototoxicity has been significantly prevented by MOL.

Abstract
The protective effect of aliskiren on ischemia-reperfusion (I/R) injury in the heart and brain has been reported. Whether or not this protective effect extends into the alleviation of renal I/R injury is not known. Therefore, we investigated the protective effect of aliskiren in the kidney in this study. Sprague-Dawley rats were randomly divided into four groups: sham control group; sham control with aliskiren pretreatment; I/R group and I/R with aliskiren pretreatment. Aliskiren (3mg/kg) or vehicle was administrated intravenously via vena cava. Blood samples and the left kidneys were then collected to check for renal function, angiotensin II (Ang II), apoptosis and oxidative stress levels. Compared with the sham rats, serum creatinine (SCR) and blood urea nitrogen (BUN) were significantly increased in the I/R rats, accompanied by histopathological damage to the kidney, which included tubular cell swelling, desquamation, and cast formation. There were also more apoptotic cells and leukocyte infiltration in the I/R rats than in the sham rats. Pretreatment with aliskiren ameliorated I/R induced renal injury, i.e. reduced SCR and BUN levels, ameliorated renal histopathological changes, and decreased the apoptosis of cells and leukocyte infiltration in kidney. I/R injury also decreased superoxide dismutase (SOD) and glutathione (GSH-reduced form) levels, which were blocked with the aliskiren pretreatment. Aliskiren pretreatment exerts a protective effect on ischemia/reperfusion injury in the kidney, via amelioration of oxidative stress, and reduction in leukocyte infiltration and cellular apoptosis.

Abstract
Despite extensive studies, there is no effective treatment currently available other than pirfenidone for idiopathic pulmonary fibrosis. A protective effect of pantothenic acid and its derivatives on cell damage produced by oxygen radicals has been reported, but it has not been tested in bleomycin (BLM)--induced pulmonary fibrosis in rats. Therefore, we aimed to investigate the preventive effect of dexpanthenol (Dxp) on pulmonary fibrosis. Thirty-two rats were assigned to four groups as follows: (1) control group, (2) dexpanthenol (Dxp) group; 500 mg/kg Dxp continued intraperitoneally for 14 days, (3) bleomycin (BLM) group; a single intratracheal injection of BLM (2.5 mg/kg body weight in 0.25-ml phosphate buffered saline), and (4) BLM + Dxp-treated group; 500 mg/kg Dxp was administered 1 h before the intratracheal BLM injection and continued for 14 days i.p. The histopathological grades of lung inflammation and collagen deposition, tissue levels of malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and myeloperoxidase (MPO) were measured. BLM provoked inflammation and collagen deposition (p < 0.0001), with a marked increase in myeloperoxidase (MPO) activity resembling increased inflammatory activity (p < 0.0001), which was prevented by Dxp (p < 0.0001, p = 0.02). BLM reduced tissue activities of SOD, GPx, and CAT compared to controls (p = 0.01, 0.03, 0.009). MDA was increased with BLM (p = 0.003). SOD (p = 0.001) and MDA (p = 0.016) levels were improved in group 4. The CAT levels in the BLM + Dxp group were close to those in the control group (p > 0.05). We showed that Dxp significantly prevents BLM-induced lung fibrosis in rats. Further studies are required to evaluate the role of Dxp in the treatment of lung fibrosis.
