Abstract
Hemorrhagic cystitis is a recognizable complication of cyclophosphamide (CYP) attributable to its lively metabolite acrolein, which produces urothelial injury. The study intended to examine the uroprotective efficacy of total ginsenosides in Chinese ginseng (TGCG) in CYP-induced hemorrhagic cystitis. In total, 24 virgin female rats were randomized into four groups as follows: group 1 (control group; injected with normal saline), group 2 (injected with CYP plus a placebo with normal saline), group 3 (given CYP and TGCG (200 mg/kg)), and group 4 (given CYP and 2-mercaptoethane sulfonate sodium (Mesna, 30 mg/kg)). An evaluation by cystometry was conducted. Values of the voiding interval were assessed in anesthetized rats and histological examinations of the bladders were measured. In the cystometry analysis, the voiding interval was significantly reduced in the CYP group. TGCG and Mesna significantly increased in the voiding interval values, individually. Bladder edema and urothelial injury were examined after contact with CYP. Contrasted to the group given CYP, CYP-induced hemorrhagic cystitis, TGCG significantly increased the urothelial thickness, and significantly reduced scores of mucosal break and submucosal edema in the bladder. In conclusion, these findings mean that the treatment with TGCG in CYP rats can avoid hemorrhagic cystitis. TGCG decreases urothelial injury. TGCG may participate as the chief character of uroprotection in CYP-induced hemorrhagic cystitis.

Abstract
Hyperbaric oxygen therapy (HBOT) continues to show effectiveness in the treatment of several diseases and benefits such as fibroblast proliferation, capillary angiogenesis, and decreasing edema, especially in hemorrhagic cystitis (HC). We report a case of a 15-year-old male with chronic myelogenous leukemia status posthaploidentical stem cell transport with BK virus in the United States to be treated by HBOT. The patient received a total of 30 HBOT treatments for 90 minutes at 2 ATA. After HBOT treatments, patient showed signs of improvements such as cessation of hemorrhage cystitis. The findings of this case support and shows that there is growing evidence for the use of HBOT as adjunctive therapy for patients with BK virus associated with HC after stem cell transplantation.

Abstract
To find a relationship between clinical and sonographic appearance of hemorrhagic cystitis (HC) in pediatric hematooncology patients. Clinical and sonographic findings of 31 children (M:F = 18:13; mean age, 12.7 years) with HC in pediatric hematooncology patients were reviewed. For each patient, the onset of HC after transplantation, use of bladder-toxic agent, presence of BK viruria, and duration of disease were reviewed. Sonographic findings including bladder wall thickness (BWT), the type of bladder wall thickening (nodular vs. diffuse), occurrence of hydronephrosis or pyelonephritis were reviewed. We analyzed sonographic appearance and clinical manifestations of HC. HC occurred within 4 months after HSCT/BMT. 27 patients (87.0 %) were positive for BK viruria and 24 patients (77.4 %) took bladder-toxic agents. On sonography, nodular type bladder wall thickening was more frequent (54.8 %), and BWT was thicker in this group (p = 0.003). There was a positive correlation between the BWT on initial sonography and duration of cystitis (r2 = 0.340). Hydronephrosis developed in 25.8 % of patients with HC, and as HC persisted longer, hydronephrosis occurred more (p = 0.004). In patients with HC after HSCT/BMT, the BWT on initial sonography correlates well with the duration of cystitis. And, longer time of HC develops the risk of hydronephrosis.

Abstract
BK virus-associated hemorrhagic cystitis (BKV-HC) is a common and major cause of morbidity in recipients of allogeneic hematopoietic stem cell transplantation. A 32-year-old woman developed severe BKV-HC on day 24 after cord blood transplantation (CBT). Despite supportive therapies - such as hyperhydration, forced diuresis, and urinary catheterization - macroscopic hematuria and bladder irritation persisted for over a month. Hyperbaric oxygen (HBO) therapy at 2.1 atmospheres for 90 min per day was started on day 64 after CBT. Macroscopic hematuria resolved within a week, and microscopic hematuria was no longer detectable within 2 weeks. Hematuria did not recur after 11 sessions of HBO therapy, and no significant side effects were observed during or after treatment. HBO therapy could thus be useful in controlling refractory BKV-HC after CBT.

Abstract
The protective roles of lipoic acid (LA)/vitamin C (VC) and mesna on preventing cyclophosphamide (CYP)-induced haemorrhagic cystitis (HC) were investigated. Swiss mice were divided into five groups randomly. HC was induced by a single dose of CYP injection (150-mg kg(-1) bodyweight). Group I was injected with saline (four times in total) throughout as control group. Group II received CYP and three equal doses of saline. Group III received CYP and three doses of mesna, whereas Group IV (or Group V) received CYP, mesna + two doses of VC (or LA). All injections were performed intraperitoneally. After 24 h of cystitis induction, the bladders were collected for all the experiments. Histological characterization showed that CYP injection resulted in severe HC. Reactive oxygen species (ROS) and thiobarbituric acid reactive substances' levels were increased in CYP group. The activities of antioxidant enzymes, e.g. superoxide dismutase, catalase, glutathione S-transferase and glutathione peroxidase, were inhibited significantly in CYP groups, respectively. In addition, activation of c-jun N-terminal kinases (JNK) and p38 mitogen-activated protein kinase (MAPK) may be involved in the mechanism of CYP-induced HC but not extracellular signal regulated kinases (ERK). Significant suppression of p38 phosphorylation on Group V suggests that LA and mesna may have synergistic beneficial effect. In Groups III-V, all the parameters of HC and oxidative stress were inhibited significantly. Taking together, we found that these results illustrated that ROS play an important role on CYP-induced HC and the administration of LA/VC with mesna may have therapeutic potential against CYP-induced bladder HC.

Abstract
HC is a possible cause of morbidity and extended hospitalization after HSCT. Recent studies have reported the efficiency of HOT in adult patients who underwent allogeneic HSCT, but data in children are scarce. We report our single center experience with HOT in late-onset HC after HSCT. Treatment with HOT consisted of daily sessions of breathing 100% O(2) for a total of 75 min in the hyperbaric chamber with a minimum of eight sessions. HOT had been associated with a concomitant treatment with oral oxybutynin, hyperhydration and/or irrigation of the bladder through the catheter. Cidofovir had been administered based on the demonstration of viral infection. Between 2004 and 2011, 10 patients developed severe HC after a median of 26 days after HSCT. HOT was started after a median of six days since the clinical diagnosis of HC. After a median of 10 sessions of HOT, seven of 10 patients were in complete remission. HOT is a well-tolerated procedure also in the pediatric setting. The early start of HOT might be effective in the treatment of HC offering advantages in terms of duration of symptoms and hospitalization.

Abstract
Late-onset hemorrhagic cystitis (HC) after allogeneic hematopoietic stem cell transplantation (HSCT) has been associated with BK virus (BKV). Antiviral drugs are of limited efficacy and the optimal treatment for HC has not yet been established. Hyperbaric oxygen (HBO) may benefit these patients. We, therefore, retrospectively evaluated the effectiveness of HBO therapy in 16 patients with HC after allogeneic HSCT. All 16 patients had macroscopic hematuria and BKV infection. Patients received 100% oxygen in a hyperbaric chamber at 2.1 atmospheres for 90 min, 5 days per week, with a median 13 treatments (range, 4-84). Fifteen patients (94%) showed complete resolution of hematuria. Median urinary DNA BKV titers declined after HBO (P<0.05). Patients started on HBO earlier after diagnosis of HC responded sooner (P<0.05). HBO was generally well tolerated and proved to be a reliable option for this difficult to manage condition.

Abstract
OBJECTIVE To investigate the protective roles of type 4 phosphodiesterase (PDE4) inhibitor in cyclophosphamide (CYP)-induced haemorrhagic cystitis, as the PDE4 inhibitor has anti-inflammatory effects but its characterization is still unknown in urinary tract diseases. MATERIALS AND METHODS In female Sprague-Dawley rats, CYP was administered intraperitoneally and bladders were harvested 24 h after CYP injection. In another group, rolipram as a PDE4 inhibitor was administered before CYP treatment. The effects and mechanisms of CYP with/without rolipram pretreatment were evaluated by microscopic features, bladder wet weight, myeloperoxidase (MPO) activity, nitric oxide (NO)-metabolite production and expression levels of inflammation-related genes. RESULTS CYP injection resulted in severe cystitis. Pretreatment with rolipram significantly reduced the increase in bladder wet weight and MPO activity, and ameliorated histological inflammatory changes caused by CYP. The levels of inflammation-related transcripts including inducible NO synthase (iNOS), interleukin-1beta and tumour necrosis factor-alpha, induced by CYP, were down-regulated significantly by pretreatment with rolipram. Also, rolipram reduced the NO-metabolite production and iNOS protein expression in the immunohistochemical examination. CONCLUSION These results indicate that rolipram can attenuate the development of CYP-induced cystitis in rats by suppressing cytokine production and iNOS induction. Thus, treatment with PDE4 inhibitor has potential clinical implications of the prevention of bladder inflammatory diseases.

Abstract
PURPOSE Hemorrhagic cystitis (HC) is a limiting side effect of chemotherapy with ifosfamide (IFS). Mesna is the drug of choice for prevention of HC. In this study, we analyzed cystoscopic and histological changes present in bladders of patients using IFS with mesna prophylaxis. METHODS Thirty-three patients selected for IFS plus three doses of mesna chemotherapy regime were assigned at random to two groups: Group I or reference group consisted of 18 patients yet untreated. Group II consisted of 15 patients in whom urinalysis and cystoscopy plus vesical biopsy were performed only 24 h after receiving the last dose of IFS. The cystoscopic and histological findings were used as parameters for evaluating the results. For the former the criterion adopted was macroscopic vesical changes in accordance with Gray's criteria. Histological analyses were performed by evaluation method especially adapted to this study. RESULTS Even under treatment with three doses of mesna, 66.7% of patients presented cystoscopic alterations and 100% showed bladder mucosa microscopic alterations such as edema, exocytosis, and hemorrhage. CONCLUSIONS The standard protocol used for prevention of IFS-induced HC with three doses of mesna does not completely prevent bladder damage. The histopathological criteria used in this study for observation of inflammatory events allowed staging the intensity of IFS-induced urothelial and mucosal injury.

Abstract
OBJECTIVES To investigate whether an endogenous prostaglandin (PG) D2 metabolite, 15-deoxy-Delta12,14-PGJ2 (15d-PGJ2), can attenuate cyclophosphamide (CYP)-induced cystitis in the rat. METHODS Male Sprague-Dawley rats received a single intraperitoneal injection of CYP (200 mg/kg). In a separate group of animals, 15d-PGJ2 (10 and 100 microg/kg intraperitoneal bolus 10 minutes before and 24 hours after CYP injection) or a selective inducible nitric oxide synthase (iNOS) inhibitor, N-(3-(aminomethyl)benzyl)acetamidine ([1400W] 10 mg/kg intraperitoneal bolus 10 minutes before and 12 and 24 hours after CYP injection), was administered. At 48 hours after CYP injection, the rats were killed, and tissues were removed for evaluation of cystitis. RESULTS CYP injection resulted in severe cystitis. 15d-PGJ2, as well as 1400W, significantly reduced the increase in plasma protein extravasation (Evans blue dye method), iNOS enzymatic activity, urinary excretion of nitric oxide metabolites, and myeloperoxidase activity in the bladder caused by CYP. Moreover, 15d-PGJ2 significantly decreased the cytokine interleukin-1beta in the bladder. In addition, 15d-PGJ2 significantly reduced the degree of CYP-induced bladder tissue damage and increase in immunohistochemical staining for iNOS in the bladder. CONCLUSIONS These results indicate that 15d-PGJ2 can attenuate the development of CYP-induced cystitis by suppression of cytokine production and iNOS induction. Thus, treatment with cyclopentenone prostaglandins such as 15d-PGJ2 may be effective against CYP-induced cystitis.

Abstract
Reperfusion injury, caused by free oxygen radicals, is a chain of events that occurs in tissues exposed to a constant period of ischemia. The antioxidant vitamins E and C (VEC) and hyperbaric oxygenation (HBO) have beneficial effects in treating ischemic tissues following skin flap operations. In our study, we aimed to compare the effects of VEC and/or HBO in ischemia-reperfusion injury induced by free oxygen radicals in an experimental rat epigastric island skin-flap model. Eight hours of ischemia was provided by clamping the inferior epigastric pedicle following the flap elevation. The flap survey was determined to be 28.6% in controls, 59.2% in HBO group, 66.3% in VEC + HBO group, and 82% in VEC group (p < 0.05). We conclude that although HBO and/or VEC increased the flap viability significantly by reducing ischemia-reperfusion injury, the most promising results were obtained in the antioxidant vitamins group.

Abstract
To compare the classical uroprotective efficacy of mesna (2-mercaptoethanesulfonic acid) with ternatin (flavonoid isolated from Egletes viscosa Less.) in cyclophosphamide (CYP) and ifosfamide (IFS) induced hemorrhagic cystitis (HC). Male Wistar rats received an intraperitoneal injection of saline, CYP or IFS and were treated with saline or mesna, 5 min before, 4 and 8 h after CYP or IFS administration. In other animals, 1, 2 or 3 doses of mesna were replaced with ternatin or 3 doses of mesna were replaced with dimethylsulphoxide (DMSO), ternatin diluent. In an additional group, the last 2 doses of mesna were replaced with saline. HC was evaluated 24 h after CYP or IFS administration. CYP or IFS treatment induced marked changes in macroscopic and microscopic evaluation and in bladder wet weight (BWW), and these alterations were significantly inhibited by treatment with 3 doses of mesna, as well as by the replacement of 1 or 2 doses of mesna with ternatin. The replacement of 2 doses of mesna with saline or all doses of mesna with ternatin or DMSO did not prevent HC. In conclusion, the replacement of 1 or 2 doses of mesna with ternatin efficiently blocked CYP- or IFS-induced HC, however mesna is necessary for initial uroprotection.

Abstract
AIM Hemorrhagic cystitis (HC) is a limiting side-effect of chemotherapy with ifosfamide (IFS). In the study presented here, we investigated the use of dexamethasone in combination with mesna for the prevention of IFS-induced HC. METHODS Male Wistar rats (150-200 g; 6 rats per group) were treated with saline or mesna 5 min (i.p.) before and 2 and 6 h after (v.o.) administration of IFS. One, two or three doses of mesna were replaced with dexamethasone alone or with dexamethasone plus mesna. Cystitis was evaluated 24 h after its induction by the changes in bladder wet weight and by macroscopic and microscopic analysis. RESULTS The replacement of the last dose or the last two doses of mesna with dexamethasone reduced the increase in bladder wet weight induced by IFS by 84.79% and 89.13%, respectively. In addition, it almost abolished the macroscopic and microscopic alterations induced by IFS. Moreover, the addition of dexamethasone to the last two doses of mesna was more efficient than three doses of mesna alone when evaluated microscopically. CONCLUSION Dexamethasone in combination with mesna was efficient in blocking IFS-induced HC. However, the replacement of last two doses of mesna with saline or all of the mesna doses with dexamethasone did not prevent HC.

Abstract
Combination chemotherapy, often in conjunction with surgery and external radiotherapy, is utilized in most children with tumors of the genitourinary tract. These chemotherapeutic agents are capable of causing a variety of delayed toxicities. Common late complications include cardiotoxicity associated with prior exposure to an anthracycline, pulmonary dysfunction, infertility in males due to prior therapy with alkylating agents, and secondary leukemia in individuals treated with epipodophyllotoxins.

Abstract
The aim of this research was to observe the effects of cyclophosphamide and its uroprotective agents, mesna and hyperbaric oxygen (HBO), on the motility of urinary bladder muscle in guinea pigs. In the experimental groups, mesna and cyclophosphamide were intraperitoneally injected at a dose of 21.5 mg/kg and 68.1 mg/kg, respectively. For the combination of mesna and cyclophosphamide, one dose of mesna was injected 20 min before cyclophosphamide administration and three additional injections of mesna were repeated every three hours. A total of 8 HBO exposures were performed at 2.8 ATA for 90 min twice daily for another experimental group. In the HBO and cyclophosphamide combined group 5 HBO exposures were given prophylactically before cyclophosphamide. The combination of mesna, HBO and cyclophosphamide was administered by the same procedure. The contractions obtained in response to acetylcholine (ACh, 10(-4) M) in the control group were reduced using cyclophosphamide and HBO individually, but not by mesna. However, the contractions belonging to the various combinations of these three agents were not different from those seen in the control group. On the other hand, the combinations of cyclophosphamide, mesna and HBO showed higher responses to ACh than the groups in which cyclophosphamide and HBO were used individually, while the responses elicited by the cyclophosphamide and HBO combination were greater than those seen in the group treated with HBO only.

Abstract
Chemotherapy with oxazaphosphorines, such as cyclophosphamide (CYP), is often limited by unacceptable urotoxicity. Without uroprotection, hemorrhagic cystitis (HC) becomes dose-limiting. To compare the uroprotective efficacy of classical 2-mercaptoethanesulfonic acid (Mesna) treatment with dexamethasone in CYP-induced HC, male Wistar rats (150-200 g; N = 6 in each group) were treated with saline or Mesna (40 mg/kg, ip) immediately and 4 and 8 h after ip administration of CYP (200 mg/kg). One, 2 or 3 doses of Mesna were replaced with dexamethasone (1 mg/kg, ip). The animals were sacrificed 24 h later. Cystitis was evaluated by determining the changes in bladder wet weight (BWW) and by macroscopic and microscopic analysis. CYP treatment induced a marked increased in BWW (162%, P<0.05), which was significantly inhibited by treatment with 3 doses of Mesna (P<0.05; 80%). The replacement of 1 or 2 doses of Mesna with dexamethasone reduced the increase in BWW by 83.3 and 95%, respectively. Macroscopic analysis of the bladder of rats with CYP-induced HC showed severe edema and hemorrhage, confirmed by microscopic analysis, that also showed mucosal erosion, inflammatory cell infiltration and ulcerations. The replacement of 1 or 2 doses of Mesna with dexamethasone inhibited the CYP-induced increase in BWW and almost abolished the macroscopic and microscopic alterations, with no significant difference between the effects of Mesna and dexamethasone, indicating that both drugs were efficient in blocking HC. However, although the replacement of all Mesna doses with dexamethasone reduced the edema, it did not prevent HC, suggesting that Mesna is necessary for the initial uroprotection.
