Abstract
BACKGROUND Myocardial necrosis is one of the most common cardiac and pathological diseases. Unfortunately, using the available medical treatment is not sufficient to rescue the myocardium. So that, we aimed in our model to study the possible cardioprotective effect of roflumilast (ROF) in an experimental model of induced myocardial injury using a toxic dose of isoprenaline (ISO) and detecting the role of vascular endothelial growth factor/endothelial nitric oxide synthase (VEGF/eNOS) and cyclic guanosine monophosphate/cyclic adenosine monophosphate/ sirtuin1 (cGMP/cAMP/SIRT1) signaling cascade. MATERIALS AND METHODS Animals were divided into five groups; control, ISO given group (150 mg/kg) i.p. on the 4th and 5th day, 3 ROF co-administered groups in different doses (0.25, 0.5, 1 mg/kg/day) for 5 days. RESULTS Our data revealed that ISO could induce cardiac toxicity as manifested by significant increases in troponin I, creatine kinase-MB (CK-MB), lactate dehydrogenase (LDH), malondialdehyde (MDA), tumor necrosis factor alpha (TNFα), and cleaved caspase-3 with toxic histopathological changes. Meanwhile, there were significant decreases in reduced glutathione (GSH), total antioxidant capacity (TAC), VEGF, eNOS, cGMP, cAMP and SIRT1. However, co-administration of ROF showed significant improvement and normalization of ISO induced cardiac damage. CONCLUSION We concluded that ROF successfully reduced ISO induced myocardial injury and this could be attributed to modulation of PDE4, VEGF/eNOS and cGMP/cAMP/SIRT1 signaling pathways with antioxidant, anti-inflammatory, and anti-apoptotic properties.

Abstract
This study aimed to explore the possible cytoprotective effects of exenatide, a glucagon-like peptide-1 (GLP-1) receptor agonist, in the testicles of diabetic rats. Exenatide has numerous advantageous properties in addition to its hypoglycemic effect. However, its impact on testicular tissue in diabetes needs more clarification. Therefore, rats were divided into control, exenatide-treated, diabetic and exenatide-treated diabetic groups. Blood glucose and serum levels of insulin, testosterone, pituitary gonadotropins and kisspeptin-1 were measured. Real-time PCR for beclin-1, p62, mammalian target of rapamycin (mTOR), and AMP-activated protein kinase (AMPK), were estimated in testicular tissue in addition to markers of oxidative stress, inflammation, and endoplasmic reticulum stress. Also, immuno-expression of protein P53, nuclear erythroid factor2 (Nrf2) and vimentin was conducted. Exenatide was able to attenuate diabetic toxic changes and enhance autophagy in testicular tissue. These results indicate the protective effect of exenatide against diabetic testicular dysfunction.

Abstract
OBJECTIVE Polycystic ovary syndrome (PCOS) is a prevalent endocrine health problem during the childbearing period that seriously affects fertility in females. Fenofibrate, a peroxisome proliferator-activated receptor-alpha (PPARα) agonist, showed beneficial effects in models of endocrine disturbances. Thus, we evaluated the potential therapeutic effect of fenofibrate in experimental PCOS. MATERIALS AND METHODS Rats received oral fenofibrate (300 mg/kg/day) for three weeks following a three-week PCOS induction regimen using oral letrozole (1 mg/kg/day). We determined the changes in body weight, levels of serum testosterone, insulin, anti-Müllerian hormone (AMH), ovarian malondialdehyde (MDA), superoxide dismutase (SOD), and tissue tumor necrosis factor-alpha (TNFα) and CD95 protein expressions. The tissue expression of interleukin-10 (IL10) and PPARα genes was determined. RESULTS Letrozole-treated rats showed successful induction of PCOS, confirmed by histopathology and significantly increased body weight, testosterone, insulin, AMH, and MDA, and decreased SOD. Ovaries of untreated PCOS rats showed increased TNFα and CD95 and decreased PPARα and IL10 expression. Administration of fenofibrate ameliorated the letrozole-induced PCOS changes. CONCLUSIONS Fenofibrate-mediated amelioration of PCOS in rats is attributed partly to its antioxidant, anti-inflammatory, and anti-apoptotic properties and activation of PPARα.

Abstract
Hepatic ischemia/reperfusion (HIR) is the most common type of liver injury following several clinical situations. Modulating oxidative stress and inflammation by Nrf2/HO-1 and TLR4/MYD88/NF-κB pathways, respectively, is involved in alleviating HIR injury. Paeonol is a natural phenolic compound that demonstrates significant antioxidant and anti-inflammatory effects. The present study explored the possible protective effect of paeonol against HIR injury and investigated its possible molecular mechanisms in rats. Rats were randomly divided into four groups: sham-operated control, paeonol-treated sham-operated control, HIR untreated, and HIR paeonol-treated groups. The results confirmed that hepatic injury was significantly aggravated biochemically by elevated serum levels of alanine transaminase and aspartate transaminase, as well as by histopathological alterations, while paeonol reduced the increase in transaminases and alleviated pathological changes induced by HIR. Additionally, paeonol inhibited the HIR-induced oxidative stress in hepatic tissues by decreasing the upraised levels of malondialdehyde and nitric oxide and enhancing the suppressed levels of reduced glutathione and superoxide dismutase activity. Furthermore, paeonol activated the protective antioxidative Nrf2/HO-1 pathway. The protective effect of paeonol was associated with inhibiting the expression of the inflammatory key mediators TLR4, MYD88, NF-κB, and TNF-α. Finally, paeonol inhibited the increased mRNA levels of the pro-apoptotic marker Bax and enhanced the reduced mRNA levels of the anti-apoptotic marker Bcl-2. Taken together, our results proved for the first time that paeonol could protect against HIR injury by inhibiting oxidative stress, inflammation, and apoptosis.

Abstract
Diabetic heart is one of the common complications of diabetes mellitus. Platelet-rich plasma (PRP) is an autologous product rich in growth factors that can enhance tissue regeneration. This work was conducted to study the PRP ability to improve diabetes-inducing cardiac changes. Also, it sheds more light on the possible mechanisms through which PRP induces its effects. Rats were divided into; control, PRP, diabetic, and PRP-diabetic groups. Cardiac specimens were obtained and processed for biochemical, histological, and immunohistochemical study. The diabetic group exhibited a significant increase in cardiac oxidative stress, inflammation, and cardiac injury markers if compared with the control group. Additionally, the cardiac tissue showed variable morphological changes in the form of focal distortion and loss of cardiac myocytes. Distorted mitochondria and heterochromatic nuclei were observed in the cardiac muscle fibers. The mean number of charcoal-stained macrophages, and mean area fraction for collagen fibers, mean number of PCNA-immune positive cardiac muscle were significantly decrease in PRP- diabetic group. Collectively, the results showed that PRP treatment ameliorated most of all these previous changes. CONCLUSION: PRP ameliorated the diabetic cardiac injury via inhibition of oxidative stress and inflammation. It was confirmed by biochemical, histological, and immunohistochemical study. It could be concluded that PRP could be used as a potential therapy for diabetic heart.

Abstract
C-peptide is gaining much interest recently due to its well-documented beneficial effects on multiple organ dysfunction induced by diabetes. Our study was designed to investigate the effect of C-peptide on hepatocellular dysfunction in diabetic rats. Wistar male rats were separated into four groups: control, diabetic, diabetic + insulin, and diabetic + C-peptide. Serum levels of glucose, insulin, and liver biomarkers were assessed. Liver sections were collected for histopathological examination and immuno-histochemical assessment of tumor necrosis factor alpha (TNF-α). Oxidative stress markers and gene expression of inducible nitric oxide synthase (iNOS), transforming growth factor beta 1 (TGF-β1), and glucose-6-phosphatase (G6Pase) were also measured in liver tissues. C-peptide administration prevented hepatic dysfunction induced by diabetes to a similar extent as that of insulin which was confirmed microscopically. We concluded that C-peptide could be used as an alternative therapy to insulin to correct hepatocellular dysfunction associated with type 1 diabetes mellitus (T1DM).

Abstract
BACKGROUND Cilostazol, a phosphodiesterase 3 inhibitor (PDE3I), is a platelet aggregation inhibitor and vasodilator that is useful for treating intermittent claudication. Experimental studies have shown that cilostazol has potent anti-inflammatory, anti-oxidant effects effects. OBJECTIVES Although the hepatoprotective effect cilostazol has been studied, the molecular mechanisms of such protection, including: the nuclear factor-erythroid 2-related factor 2 (Nrf2) / hemoxygenase (HO-1) and the phosphoinositide 3-kinase (PI3K) /serine/threonine kinase (Akt) pathways are not fully explored, which is the aim of this study. METHODS To achieve the aim of this study, 35 rats were grouped into: control groups, liver injury group (model- non treated: injected with thioacetamide (TAA), 150 mg/kg, i.p.), and two cilostazoltreated groups (treated with cilostazol 10 and 50 mg/kg, p.o.). The rats were treated for 8 days and injected with TAA on the 7th day of the experiment and sacrificed 48 hours after TAA injection. RESULTS The model group showed evidence of liver injury as indicated by the elevation of liver enzymes and confirmed by histopathological findings. TAA-induced liver injury was accompanied by down-regulation of the cytoprotective pathways: PI3K/Akt and Nrf2/HO-1 mRNAs. Cilostazol administration ameliorated TAA-induced liver injury, where it caused a significant improvement in the activity of liver enzymes as well as in the histopathological changes. Such an effect was associated with a significant increase in the expression of PI3K/Akt and Nrf2/HO-1 mRNAs as detected by Real-time reverse transcription polymerase chain reaction (RT-PCR). CONCLUSION Cilostazol protected rats against TAA hepatotoxicity through up-regulation of PI3K/Akt and Nrf2/HO-1 gene expression.

Abstract
The obligatory use of cytotoxic drugs to face the malignant tumors results in survivors that suffer from long term health problems. Fertility problems, especially in young boys, exert one of the major consequences of chemotherapy treatment that needs resolution. We investigate the potential effect of the cysteinyl leukotriene receptor antagonist montelukast on doxorubicin-induced testicular damage. Five groups of adult Wistar male rats were subjected to the following treatment; vehicle for the control group, montelukast (20 mg/kg orally daily for 10 days) for the drug control, doxorubicin (12 mg/kg intraperitoneal injection once at 5th day) for the toxic group, montelukast at 10 mg/kg + doxorubicin, montelukast at 20 mg/kg + doxorubicin. The period of the experiment was 10 days administration of montelukast, while doxorubicin was injected at the 5th day. Results of serum testosterone, testicular lipid peroxidation, antioxidant status, and histopathology revealed protection of montelukast against doxorubicin-induced testicular damage. The pro-apoptotic caspase 3 and the pro-inflammatory tumor necrosis factor-alpha were examined immunohistochemically and showed a significant decrease with montelukast treatment as compared to doxorubicin group. Doxorubicin increased gene expression of matrix metalloproteinase 9 and decreased peroxisome proliferator activated receptor gamma. Montelukast treatment restored their expressions to normal values. In conclusion, montelukast administration can ameliorate the testicular damage induced by doxorubicin based on its anti-inflammatory, antioxidant and anti-apoptotic effects as well as by of modulation of important genes expression.

Abstract
INTRODUCTION Diabetic nephropathy (DN) is one of the critical complications of diabetes mellitus and the main cause of chronic renal dysfunction. The pathogenic mechanism causing the disease remains unclear and there is a lack of effective treatment methods so novel strategies are needed for DN management. The aim of this study, therefore, is to evaluate the effect of liraglutide as glucagon-like peptide-1 analogue and its underlying mechanisms on induced DN in rats MATERIALS AND METHODS: Sixty rats were divided into control group, diabetic group, and liraglutide-treated group. At the end of experiment, renal CTGF and BMP-7 messeger RNA expression were determined. Blood sugar, serum urea, and creatinine were measured. Also, histopathological changes were studied. RESULTS Liraglutide can improve renal alterations associated with diabetes as it reduced CTGF expression and increased BMP-7 expression. In the same time, it could improve histopathological changes and renal function tests. CONCLUSION These findings influence the beneficial use of liraglutide for the management of DN in patients with diabetes mellitus.

Abstract
Melatonin, the pineal gland hormone, plays a crucial role in regulation of neuroendocrine and defensive functions, free radicals neutralization, and suppresses angiogenesis, proliferation and cancer. The purpose of designing our study is to assess the effect of estradiol benzoate and its combination with melatonin on uteri of female albino rats. For 4 weeks, the present study was conducted on thirty six female rats separated into 3 groups: Control group (rats received the vehicle), EB group (rats were treated by estradiol benzoate (600 μg/kg intramuscular) for induction of endometrial hyperplasia), and EB+Mel group (rats were treated with estradiol benzoate (600 μg/kg) plus melatonin (50 µg/ml) added to drinking water. Melatonin administration reduced estradiol benzoate-induced endometrial hyperplasia and prevented the occurrence of atypia associated with a significant reduction in lipid peroxide level and NF-κB mRNA and a significant rise in immune-expression of caspase-3, interleukin-2 (IL-2) mRNA and total antioxidant levels in uterine tissues. The results demonstrated that melatonin reduced estradiol benzoate action on the endometrium.

Abstract
Paeonol, a natural phenolic compound, possesses diverse beneficial effects including antioxidant and anti-inflammatory effects. Gastric ulcer is still the most prevalent irritant illness among the gastrointestinal diseases. The present study explored the protective effect of paeonol at two dose levels in indomethacin (IND)-induced gastric ulcer in rats. Forty-eight male Wistar rats were arranged into six groups: control, paeonol-treated, IND-treated, IND/paeonol (low and high doses)-treated, and ranitidine-treated groups. The oxidative status was evaluated by determining malondialdehyde level, superoxide dismutase activity, reduced glutathione content as well as hemoxygenase-1 (HO-1) gene expressions, and the antioxidant protein; NAD(P)H quinone oxidoreductase 1 (NQO1) immunostaining. The pro-inflammatory genes nuclear factor κB (NF-κB) and interleukin 1β (IL-1β) were estimated together with the proapoptotic gene of caspase 3. IND caused multiple gastric ulcers with evident oxidative damage and elevated pro-inflammatory and proapoptotic markers. Paeonol protected significantly, in a dose-dependent manner, the gastric mucosa from ulcerative lesion of IND similar to the reference drug ranitidine. Paeonol pretreatment diminished gastric oxidative stress and restored the gastric antioxidant capacity by elevating gastric gene expression of HO-1 and protein expression of NQO1. Paeonol also reduced NF-κB, IL-1β, and caspase 3 gene expressions. In conclusion, paeonol offered a gastroprotection dependent on its antioxidant, anti-inflammatory, and antiapoptotic effects.

Abstract
Sofosbuvir (SOF) and daclatasvir combination with or without ribavirin proved to be effective and safe in the treatment of hepatitis C virus infection. The study aimed to assess the efficacy of (SOF plus daclatasvir) combination + ribavirin in the treatment of treatment-experienced HCV genotype 4 Egyptian patients and to investigate the impact of IL-1β _31, IL-1β _511, and IL-1RN and T29C of ESR1 genes polymorphisms on treatment outcome. The study also aimed to assess the effect of the treatment on liver fibrosis. The sustained virologic response was assessed at 0, 4, 12, and 24 weeks from the beginning of treatment by RT-PCR. IL-1β _31, IL-1β _511, IL-1RN, and T29C genes polymorphisms were examined by PCR-based techniques in two groups of patients (responders and non-responders) and a control group of healthy subjects. A significant association between IL-1β_511 gene polymorphism and SOF/DAV-induced response was observed, where the "CC" genotype was the most frequent in responders while the "CT" genotype was the most frequent among non-responders (P = 0.0001, OR = 39; 95% CI = 4.7-316). IL-1RN gene polymorphism also showed significant associations with response to treatment, genotypes that include allele "1" were the most frequent in responders, particularly the homozygous genotype "1/1" (P = 0.0001, OR = 2.3; 95% CI = 1.57-3.2). However, the genotypes "4/4" and "2/4" were the most frequent in non-responders; (P = 0.0001). At least 71% of the responders carry allele "1" while 54% of non-responders were allele "4" carriers (P value = 0.0001. OR = 2.8; 95% CI = 6.4-134.2). Liver fibrosis is significantly improved regardless of the response. © 2018 IUBMB Life, 70(11):1156-1163, 2018.

Abstract
Nearly all men who reach average life expectancy have prostate disease. The most common is benign prostatic hyperplasia (BPH). Peroxisome proliferator-activated receptor alpha (PPARα) had protective effect in different models, but still, there are no studies explain its role in BPH. So that we investigated the effect of fenofibrate (FEN) on induced BPH by testosterone propionate (TP) (3 mg/kg/day for 4 weeks) subcutaneous injection followed by FEN (300 mg/kg/day) was given orally for 4 weeks. We measured prostate weights changes, prostatic tissue superoxide dismutase (SOD), and malondialdehyde (MDA) levels. Prostate-specific antigen (PSA), dihydrotestosterone (DHT), and total antioxidant capacity (TAC) in serum were determined. The mRNA gene expressions of proliferating cell nuclear antigen (PCNA), PPARα, and glutathione peroxidase (GPx) in prostatic tissue were also measured by quantitative real-time polymerase chain reaction. In addition, the histopathological changes and activated caspase3 immunoexpression were evaluated. Our results showed that TP succeeded in induction of BPH, which was detected by significant increase in prostate weights, prostatic tissue MDA, serum levels of DHT, PSA, and mRNA gene expression of PCNA but significant decrease in PPARα and GPx gene expression. Moreover, TAC in serum and SOD level in prostate tissue decreased. The histopathological examination showed typical changes of BPH with dysplastic changes with marked decrease in activated caspase3 immunoexpression indicating marked suppression of the apoptotic process. FEN significantly improved all disturbed parameters of BPH model. Moreover, there are no dysplastic changes with co-administration of FEN to BPH induced group.

Abstract
Cadmium (Cd) intoxication in human occurs through inhalation of cigarette smoke and ingestion of contaminated water and food. We investigated the role of nebivolol (NEB) in Cd induced hepatotoxicity. In our study; NEB was given as (10 mg/kg/d) orally to rats for 6 weeks, in the presence or absence of hepatotoxicity induced by oral administration of Cd (7 mg/kg/d) for 6 weeks. Levels of serum liver enzyme biomarkers; alanine transaminase (ALT), aspartate transaminase (AST) and serum total antioxidant capacity (TAC) were measured. In addition; mean arterial pressure and total cholesterol levels were measured. Hepatic superoxide dismutase (SOD) and malondialdehyde (MDA) were detected. Hepatic histopathological features, inducible nitric oxide synthase (iNOS) and endothelial nitric oxide synthase (eNOS) immunoexpressions were evaluated. Tumor necrosis factor alpha (TNF-α) and B-cell lymphoma-2 (Bcl-2) mRNA gene expressions were detected using real time-PCR (rt-PCR). Our results showed marked increase in all measured parameters except SOD, TAC, eNOS immunoexpression and Bcl2 mRNA gene expression which decreased in Cd induced hepatotoxicity group. NEB showed marvelous protective effect against Cd induced changes. NEB decreased liver enzymes (ALT and AST), mean arterial pressure, total cholesterol levels, MDA, iNOS immunoexpression and TNF-α gene expression but significantly increased SOD, TAC, eNOS immunoexpression and Bcl-2 gene expression. Moreover; NEB markedly improved the histopathological changes induced by Cd. These findings prove the antioxidant, anti-apoptotic and anti-inflammatory properties of NEB and its protective role in Cd induced hepatotoxicity.

Abstract
BACKGROUND/PURPOSE The effect of sofosbuvir and daclatasvir in treatment of genotype 4 Hepatitis C Virus (HCV) is not well documented. This study investigated the safety and efficacy of sofosbuvir plus daclatasvir with or without ribavirin in treatment of HCV genotype 4 patients. The impact of therapy on liver fibrosis as well as the role of IL18 polymorphism in therapeutic outcome was assessed. METHODS One hundred HCV genotype 4 patients were categorized into 2 groups. The group 1 comprised treatment naïve patients, with total serum bilirubin ≤ 1.2 mg/10-1 L, serum albumin ≥ 3.5 g/10-1 L, INR ≤ 1.2, and platelet count ≥ 150 × 109/L. This group was treated with sofosbuvir plus daclatasvir for 12 weeks. The group 2 included Peg-IFN-α-or sofosbuvir treatment experienced, or patients with at least 2 of the following findings: total serum bilirubin > 1.2 mg/10-1 L, serum albumin < 3.5 g/10-1 L, INR > 1.2, and platelet count < 150 × 109 L-1. Group 2 was treated with sofosbuvir-daclatasvir + ribavirin for 12 weeks, with the exception of sofosbuvir treatment experienced patients, who were treated with sofosbuvir/daclatasvir + ribavirin for 24 weeks. RESULTS Sustained Virological Response (SVR12) (undetectable viremia12 weeks post-treatment), was 93.3% in group 1 and 87.5% in group 2 (total = 91%). Such high efficacy was accompanied with tolerable adverse effects as well as with significant improvement in liver fibrosis. No significant association was observed between IL18 polymorphism (rs1946518) at position -607 and achievement of SVR12 in HCV patients after treatment. CONCLUSION Sofosbuvir plus daclatasvir, with or without ribavirin achieved high efficacy and safety in HCV genotype 4 patients. Their effects were accompanied with attenuation of liver fibrosis. Further wider-scale studies are needed to evaluate the actual role of IL18 polymorphisms in treatment response with sofosbuvir/daclatasvir.

Abstract
Tramadol is a synthetic, centrally acting analgesic. It is the most consumed narcotic drug that is prescribed in the world. Tramadol abuse has dramatically increased in Egypt. Long term use of tramadol can induce endocrinopathy. So, the aim of this study was to analyze the adrenal insufficiency induced by long term use of tramadol in experimental animals and also to assess its withdrawal effects through histopathological and biochemical genetic study. Forty male albino rats were used in this study. The rats were divided into 4 groups (control group, tramadol-treated group, and withdrawal groups). Tramadol was given to albino rats at a dose of 80 mg/kg body weight for 3 months and after withdrawal periods (7-15 days) rats were sacrificed. Long term use of tramadol induced severe histopathological changes in adrenal glands. Tramadol decreased the levels of serum cortisol and DHEAS hormones. In addition, it increased the level of adrenal MDA and decreased the genetic expression of glutathione peroxidase and thioredoxin reductase in adrenal gland tissues. All these changes started to return to normal after withdrawal of tramadol. Thus, it was confirmed that long term use of tramadol can induce severe adrenal insufficiency.

Abstract
AIM OF THE STUDY Adenovector encoding tissue plasminogen activator (tPA) was shown to reduce experimental peritoneal adhesion. We investigated the targeting potential of our modified adenovector, its ability to reduce adhesions and the epigenetic role of histone methyltransferase EZH2 in adhesion formation. MATERIALS AND METHODS Control lacZ, nonmodified tPA or modified tPA vectors were instilled in the peritoneal cavity after injury in de novo adhesions or after lysis of adhesions in recurrent adhesions. Adhesion severity was scored and adhesions and liver tissues were examined for adenovirus E4 gene and tPA mRNA expression. Levels of tPA, plasminogen activator inhibitor-1 (PAI-1), transforming growth factor-β1 (TGF-β1), and EZH2 expression were measured. RESULTS E4 transcripts were detected in adhesions of nonmodified and modified and in livers of nonmodified but not in livers of modified de novo adhesions. Both nonmodified (p = 0.021) and modified vectors (p = 0.036) reduced the severity of de novo adhesions compared to lacZ vector. Levels of tPA in nonmodified (p = 0.021) and modified adhesions (p = 0.001) were elevated while PAI-1 (p = 0.013 and p = 0.001, respectively) and TGF-β1 levels (p = 0.002 and p = 0.016, respectively) were reduced compared with lacZ group. All vectors were not expressed in recurrent adhesions and severity score were not different among groups. EZH2 levels were elevated in de novo nontreated (p = 0.001) and was further increased in recurrent (p = 0.001) nontreated adhesions compared with noninjured peritoneum. CONCLUSION Modified adenovirus successfully targeted de novo adhesions but not liver tissues and reduced the severity of de novo adhesions. EZH2 is involved in the development and progression of peritoneal adhesions.
