ha-1100 and Cystitis

Cystitis is defined as an inflammation of the bladder caused by a bacterial infection, and it can be dangerous and painful when it spreads through the internal organs. In this study, antioxidant effects of hydroxylfasudil (HF) at the enzymatic and molecular level on kidney and liver tissues in cystitis rat model, which is caused by inflammation of the rat bladder with a protamine sulphate (PS), was examined. Quantitative changes of reduced glutathione (GSH) and lipid peroxidation (LPO) levels, which are a marker for oxidative stress, were determined in rat kidney and liver tissues for each groups. And then molecular and biochemical impact of HF treatment on antioxidant enzymes including superoxide dismutase (SOD) and catalase (CAT) in cystitis model were studied. The results suggest that HF could be beneficial to the renal and hepatic antioxidant system. Thus, HF might be used as a novel therapeutics agent to eliminate interstitial cystitis.

The objective of the present study was to evaluate anti-inflammatory effects of hydroxyfasudil in a protamine sulfate (PS) induced cystitis rat model. Additionally, we investigated prevention of bladder overactivity (BO), and tissue damage in these experiments.. Animals were divided into four groups. In Groups 1 and 2, chemical induced cystitis model was created by administrating intravesical PS with PE50 catheter by the transurethral route. In Group 1, Rho-kinase inhibitor hydroxyfasudil was administered intaperitoneally, and in Group 2, subjects were administered a corresponding volume of saline in the same way. In Group 3, vehicle was administered intravesically and hydroxyfasudil was administrated intraperitoneally. Group 4 was a control Group, and the vehicle was administered intravesically and intraperitoneally. Micturition frequencies were recorded. Biochemical analyses were performed for oxidative stress, and pathological evaluations were investigated. In vitro contractions of bladder tissue strips were measured in tissue-bath.. There were significantly lower Lipid peroxidase levels and higher levels of Glutathione in Group 1 than Group 2 (P = 0.016, P = 0.001, respectively). There was generally more inflammation in Group 2 than the other groups as determined by microscopy. There were significantly higher frequencies of micturition, lower volume, and mean voided maximum urine output after PS administration in Groups 1 and 2. In vitro contraction responses of bladder strips to potassium chloride and acetylcholine were statistically higher in Group 2 than Groups 1 and 3.. Significant reduction of inflammation by affecting the anti-oxidant defense systems was provided by hydroxyfasudil. Decreased in vitro responses to contractions of bladder smooth muscle strips were obtained. Hydroxyfasudil may be a potential new therapeutic option for inflammation and BO, in rat bladder.
