Abstract
Primary renal angiosarcomas (AS) are uncommon tumors with poor prognosis. Aetiology is unknown but some unproven risk factors have been described. It is difficult to discriminate these masses from renal cell carcinomas or other renal masses with imaging modalities. Immunohistochemistry plays an important role in the diagnosis. Main treatment protocol for primary renal AS is still controversial and nephrectomy with chemotherapy and/or radiotherapy seems the only treatment option. We state a primary renal angiosarcoma case for its rareness and contribution to literature.

Abstract
BACKGROUND In animal models, endoplasmic reticulum (ER) stress has been reported to play a vital role in mediating ischemia/reperfusion (I/R) injury in certain organs, such as brain, liver, and intestine. However, there are a limited number of studies examining the relationship between ER stress and torsion and detorsion (T/D)-induced testicular injury. OBJECTIVE To investigate the effects of N-acetylcysteine (NAC) on ER-stress and apoptosis in an experimental testicular I/R injury model. DESIGN A non-blinded experimental study with three arms. Rats were divided into three groups: control group, T/D group, and NAC group. In the pretreatment of the NAC group, 20 mg/kg NAC was given intraperitoneally 30 min before detorsion. Tissue 4-hydroxynonenal (4-HNE), 78-kDa glucose-regulated protein (GRP78), and activating transcription factor 6 (ATF6) levels were determined using enzyme-linked immunosorbent assay. The apoptosis levels were evaluated using terminal deoxynucleotide transferase-mediated dUTP nick-end label assay. RESULTS In T/D group, tissue 4-HNE, GRP78, ATF6, and apoptotic index levels were significantly higher than control group. These increases were significantly reversed with NAC pretreatment. DISCUSSION There are some potential drugs that have been shown to reduce ER stress in the experimental ischemia model, and it is questioned that these drug candidates can be used as a therapeutic agent in the treatment of ischemic diseases in the near future. This study was not without limitations. First, the authors applied NAC only 20 mg/kg. In a future study, a dose-dependent assay should be performed to assess the likelihood of an additional testicular protective effect. One limitation of this research is also that in vivo studies cannot be extrapolated to possible effect in clinics. More experiments therefore need to be conducted to extrapolate the study findings to humans. CONCLUSION The study results showed that, after testicular torsion (TT), the ER stress-related apoptotic pathway plays a pivotal role in testicular injury. Further studies of other experimental models of TT may prove that NAC is a useful agent as an adjunctive treatment in surgical repair in human cases.

Abstract
Purpose: Despite the nerve-sparing technique, many patients suffer from erectile dysfunction after radical prostatectomy (RP) due to cavernous nerve injury. The aim of this study was to evaluate dipyridamole as a potential treatment agent of post-radical prostatectomy erectile dysfunction. Material and methods: A total of 18 male Sprague-Dawley rats were randomized into three experimental Groups (SHAM+DMSO, BCNI+DMSO and BCNI+DIP). An animal model of bilateral cavernous nerve crush injury (BCNI) was established to mimic the partial nerve damage during nerve-sparing RP. After creating of BCNI, dimethyl sulphoxide (DMSO) was administered transperitoneally as a vehicle to SHAM+DMSO and BCNI+DMSO Groups. BCNI+DIP Group received dipyiridamole (10mg/kg/day) as a solution in DMSO for 15 days. Afterwards, rats were evaluated for in vivo erectile response to cavernous nerve stimulation. Penile tissues were also analyzed biochemically for transforming growth factor-β1 (TGF-β1) level. Penile corporal apoptosis was determined by TUNEL method. Results: Erectile response was decreased in rats with BCNI and there was no significant improvement with dipyridamole treatment. TGF-β1 levels were increased in rats with BCNI and decreased with dipyridamole treatment. Dipyridamole led to reduced penile apoptosis in rats with BCNI and there was no significant difference when compared to sham operated rats. Conclusions: Although fifteen-day dipyridamole treatment has failed to improve erectile function in rats with BCNI, the decline in both TGF-β1 levels and apoptotic indices with treatment may be helpful in protecting penile morphology after cavernous nerve injury.

Abstract
OBJECTIVE We aimed to investigate the effect of mad honey on sexual performance. BACKGROUND In traditional medicine in Turkey, mad honey is used to improve appetite, to heighten mental alertness, to reduce joint pain, to eliminate gastrointestinal system pains and to increase sexual performance. METHODS In this experimental animal study eighteen Sprague Dawley male rats were randomized into three groups, a control group, a normal honey group and a mad honey group. Rats in the treatment groups were given a daily dose of 80 mg/kg normal honey or mad honey throughout the 30-day study period. Total testosterone, free testosterone, FSH, LH, estradiol, and progesterone levels were subsequently investigated from blood sera on day 30. RESULTS Comparison of blood total testosterone levels among the groups revealed significantly higher levels in the mad honey group compared to the normal honey and control groups (p = 0.006, p = 0.00). Free testosterone levels were also significantly higher in the mad honey group than in the normal honey and control groups (p = 0.023, p = 0.01). No statistically significant differences were determined for other hormonal measurements. CONCLUSIONS This study revealed a significant increase in both total and free testosterone levels in mad-honey group (Tab. 1, Fig. 2, Ref. 16).

Abstract
PURPOSE To investigate the protective effects against ischemia reperfusion injury of dipyridamole in a model of induced priapism in rats. MATERIALS AND METHODS Twenty-four male Sprague-Dawley rats were divided into four groups, control, P/R, P/R+DMSO and P/R+D. 3ml blood specimens were collected from vena cava inferior in order to determine serum MDA, IMA, TAS, TOS and OSI values, and penile tissue was taken for histopathological examination in control group. Priapism was induced in P/R group. After 1h, priapism was concluded and 30 min reperfusion was performed. In P/R+DMSO group 1ml/kg DMSO was administered intraperitoneally 30 min before reperfusion, while in P/R+D group 10mg/kg dipyridamole was administered intraperitoneally 30 min before reperfusion. Blood and penis specimens were collected after the end of 30 min reperfusion period. Sinusoidal area (μm2), tears in tunica albuginea and injury parameters in sinusoidal endothelium of penis were investigated. RESULTS Histopathological examination revealed no significant changes in term of sinusoidal area. A decrease in tears was observed in P/R+D group compared to P/R group (p<0.05). Endothelial injury decreased in P/R+D group compared to P/R group (p>0.05). There were no significant differences in MDA and IMA values between groups. A significant increase in TOS and OSI values was observed in P/R+D group compared to P/R group. A significant decrease in TAS levels was observed in P/R+D group compared to the P/R group. CONCLUSIONS The administration of dipyridamole before reperfusion in ischemic priapism model has a potential protective effect against histopathological injury of the penis.

Abstract
Introduction We evaluated and compared the serum oxidative stress and antioxidant enzymes in patients with renal cell carcinoma (RCC) and the control group. Material and methods The prospective study consisted of 97 patients with RCC (Group 1) and 80 age and sex matched healthy volunteers (Group 2). Group 1 and 2 were compared concerning serum mean total oxidant status (TOS), total antioxidant capacity (TAC), paraoxonase-1 (PON-1), arylesterase, total thiol, catalase (CAT), myeloperoxidase (MPO) and ceruloplasmin. Results Patients’ mean age was 58.5 ±12.3 and 56.9 ±15.8 years, respectively, in Group 1 and 2. No statistically significant differences were detected between the groups in terms of oxidative stress parameters and antioxidant capacity measured in the serum of patients including, TOS, TAC, PON1, arylesterase, total thiol, CAT, MPO, and ceruloplasmin levels (p >0.05 for all parameters). The PON-1 value was significantly higher in patients with pT1 stage than pT3 stage (p = 0.007). The arylesterase value was significantly higher in patients with Fuhrman's nuclear grade 3 than grade 2 (p = 0.035). There was no correlation between these parameters level and Fuhrman's nuclear grade, stage, or histopathological tumor type. Conclusions Our results demonstrated that evaluation of these parameters in the serum of patients with localized RCC may not be used as a marker to discriminate between patients with RCC and healthy people.

Abstract
OBJECTIVE To investigate the potential diagnostic value of plasma signal peptide, CUB (complement proteins C1r/C1s, Uegf, Bmp1) domain, epidermal growth factor (EGF)-like 1 (SCUBE1) protein in experimentally induced testicular torsion (TT). MATERIALS AND METHODS In this randomized, controlled, experimental study, 24 mature male Wistar rats were divided into four groups: 2- and 4-hour control (groups I and III, respectively), and 2- and 4-hour torsion (groups II and IV, respectively) groups. Torsion was performed by rotating the left testis 720° clockwise and maintained by fixing the testis. Plasma SCUBE1 levels and histopathological damage scores were compared. RESULTS There was significantly greater histopathological damage in the 4-hour torsion group compared with the other groups. SCUBE1 levels in this group were also higher than those in the other groups, and the difference was significant. There were significant correlations between histopathological scores and SCUBE1 levels. CONCLUSION SCUBE1, a novel marker of platelet activation, is elevated in TT. According to our results, platelet activation may play an important pathological role in tissue injury associated with testicular ischemia. Plasma SCUBE1 measurement may have diagnostic, therapeutic, or prognostic value in TT.

Abstract
OBJECTIVE To investigate the effects of tyrphostin AG 556, a tyrosine kinase inhibitor (TKI) in an experimental model of testicular ischemia-reperfusion (I/R) injury. MATERIAL AND METHODS Twenty-four adult male rats were randomly divided into four groups (n = 6): sham, torsion/detorsion (T/D), T/D + dimethylsulfoxide (DMSO) (vehicle group), and T/D + DMSO + tyrphostin AG 556. Testicular torsion was achieved by rotating the left testis 720° clockwise for 4 h. Thirty minutes before detorsion, 3 mg/kg tyrphostin AG 556 was injected transperitoneally in the AG 556 group and DMSO was injected transperitoneally in the DMSO group. After 2 h of reperfusion arterial blood samples were collected for biochemical analysis for malondialdehyde (MDA), ischemia modified albumin (IMA), SCUBE1 (signal peptide-CUB [complement C1r/C1s, Uegf, and Bmp1] and EGF [epidermal growth factor] like domain-containing protein 1), total oxidant status (TOS), total antioxidant status (TAS), and oxidative stress index (OSI) parameters, and ipsilateral orchiectomies were performed for histopathological examination based on the semi-quantitative Johnsen's mean testicular biopsy score (MTBS) in all groups. RESULTS Tyrphostin AG 556 exhibited a protective effect against I/R injury in testicular torsion. Of the biochemical parameters evaluated as a result of testicular I/R, IMA, MDA, and TOS levels were significantly elevated. There was no significant difference in terms of these biochemical parameters between the sham and AG 556 groups. Significant histopathological injury was determined by comparing the T/D and sham groups. According to histopathological injury scores, significant differences were determined between T/D and AG 556 groups and between AG 556 and sham groups. AG 556 had a superior improving effect on Johnsen's scores than DMSO. CONCLUSIONS Our results suggest that the use of tyrphostin AG 556 prior to testicular reperfusion has a protective effect against testicular I/R injury.

Abstract
OBJECTIVE To compare the effects of N-acetylcysteine (NAC) and ethyl pyruvate (EP) on experimental testicular ischemia-reperfusion (I/R) injury. DESIGN Randomized, controlled, experimental study. SETTING University hospital. ANIMAL(S) Twenty-four mature male Wistar rats. INTERVENTION(S) Rats were divided into four groups: control group, torsion-detorsion (T/D) group, EP group, and NAC group. In the pretreatment of the NAC and EP groups, 20 mg/kg NAC and 50 mg/kg EP were given intraperitoneally (IP) 30 minutes before detorsion. MAIN OUTCOME MEASURE(S) Serum ischemia-modified albumin (IMA), tissue and serum malondialdehyde, and myeloperoxidase activity levels and histopathological damage scores were then compared. RESULT(S) Ethyl pyruvate and N-acetylcysteine exhibited a protective effect against I/R injury. Of the biochemical parameters evaluated as a result of testicular I/R, only IMA levels were significantly elevated. There was a strong and significant correlation between serum IMA levels and histopathological injury scores, and the increase in serum IMA level exhibited a strong parallel with the increase in histopathological injury. In the EP group, although the histopathological injury score was similar to that of the control group, serum IMA levels were significantly elevated. CONCLUSION(S) Both NAC and EP, the effects of which on I/R injury are evaluated in the present study, reduce such injury in testicular torsion-detorsion. Comparing their effects on IMA levels, NAC may be regarded as a relatively more effective treatment than EP.

Abstract
INTRODUCTION To investigate the effect of tadalafil on Resistivity Index (RI) and Pulsatility Index (PI) in partial unilateral ureteral obstruction (PUUO). METHODS Twelve New Zealand rabbits were assigned into two groups. Baseline renal Doppler ultrasonography (USG) was performed in all rabbits. The rabbits in group 1 received tadalafil for a month (10 mg/72 h) and group 2 was defined as sham. After 1 month, in both groups left PUUO was created. Renal Doppler USG was performed to measure RI and PI parameters of both kidneys on the 4th hour and 1st and 3rd days postoperatively. RESULTS Baseline renal Doppler USG revealed that there was no difference between two kidneys in both groups. The differences in mean RI and PI values of the kidneys between the sham and tadalafil groups were not statistically significant. Compared with the preoperative values, postoperative RI and PI values for the left kidneys were significantly increased in the period from 4 h to 3 days postoperatively in the sham group (p < 0.05). However, mean RI and PI values were not increased in the tadalafil group when compared with the sham group and this difference between the two groups was significant (p < 0.05). CONCLUSIONS Tadalafil has a lowering affect on RI and PI in experimentally created PUUO.

Abstract
BACKGROUND The aim of the present study was to investigate the underlying mechanisms in the preventive effects of intravenous anesthetics on testicular ischemia-reperfusion injury. METHODS Forty male Wistar Albino rats were randomly assigned to four groups of 10 rats each. Anesthesia was induced and maintained with thiopental in groups 1 and 2 and with propofol in groups 3 and 4. Groups 2 and 4 received left testicular ischemia (torsion) for 1 h and reperfusion (detorsion) for 24 h. Groups 1 and 3 (control groups) had no testicular torsion and detorsion. At 24 h of reperfusion, animals were killed and ipsilateral testes were removed for determination of tissue nitric oxide (NO) levels and immunohistochemical evaluation of endothelial nitric oxide synthase (eNOS), inducible NOS (iNOS), and apoptosis protease-activating factor 1 (APAF-1). RESULTS Between groups 1 and 3, there were no differences in tissue NO levels and eNOS, iNOS, and APAF-1 expressions. iNOS and APAF-1 expressions were markedly increased in group 2, but these parameters were at the mild to moderate level in group 4 at 24 h of reperfusion. Also, elevated expression of iNOS was accompanied by a high NO production in group 2 compared with group 4. Although eNOS expressions were increased in both the groups (groups 2 and 4), there were no significant differences between these groups. CONCLUSIONS Propofol as an anesthetic agent may attenuate germ cell-specific apoptosis and decrease NO biosynthases through downregulation of iNOS expression in an animal model of testicular torsion and detorsion.

Abstract
BACKGROUND Testicular torsion is a urological emergency that requires immediate surgical intervention to prevent testicular damage. The aim of the study was to investigate the preventive effects of thiopental and propofol as anesthetics on testicular ischemia-reperfusion injury. METHODS Forty male Wistar Albino rats were randomly assigned to four groups of 10 rats each. During 5 h, anesthesia was induced and maintained with thiopental in groups 1 and 2 and with propofol in groups 3 and 4. Groups 2 and 4 received left testicular ischemia (torsion) during 1 h and reperfusion (detorsion) during 4 h. Groups 1 and 3 (control groups) had no testicular torsion and detorsion. At the end of 5 h, animals were killed and both ipsilateral and contralateral testes were removed for histopathologic examination and measurement of tissue MDA (malondialdehyde) and NO (nitric oxide) levels. RESULTS In the contralateral testes of all the groups, MDA and NO measurements were not different from ipsilateral testes of the control groups. Between the groups 1 and 3, there were no differences in MDA and NO levels. Although torsion/detorsion of testes in group 4 caused significantly increased levels of tissue MDA and NO values compared with group 3, ischemia-reperfusion in group 2 caused a further increase in these levels compared with group 4. The ipsilateral testes in the control groups did not show any morphological changes. Testicular torsion/detorsion in rats with thiopental anesthesia (group 2) caused significantly greater histopathologic injury levels than rats with propofol anesthesia (group 4). CONCLUSION Our results suggest that propofol as an anesthetic agent may prevent testicular damage by scavenging reactive oxygen and nitrogen species and inhibiting lipid peroxidation in an animal model of testicular torsion and detorsion.
