Amyloidosis of urinary bladder is a rare condition and may be primary or secondary in nature. A case of primary localized vesical amyloidosis (VA) in a 40-yr-old man is described confused with neoplasm by cystoscopic, urographic. Surgical specimens obtained by transurethral resection (TUR) were diagnostic and histologically revealed amyloid deposits in sub-epithelial stroma with chronic inflamm...

Amyloidosis of urinary bladder is a rare condition and may be primary or secondary in nature. A case of primary localized vesical amyloidosis (VA) in a 40-yr-old man is described which was confused with neoplasm by cystoscopic, urographic and other studies. Surgical specimens obtained by transurethral resection (TUR) were diagnostic and histologically revealed amyloid deposits in sub-epithelial...

Vascular amyloidosis (VA) is a component of aging, but both VA and aging move forward together. Although, not all age-related molecules are involved with VA, some molecules are involved in a crosstalk between both of them. However, the cellular mechanism by which, vascular cells are phenotypically shifted to arterial remodeling, is not only involved in aging but also linked to VA. Additionally,...

Amyloidosis is characterized by an abnormal extracellular deposition of amyloid in different organs, where it usually causes some type of dysfunction. Its cause is unknown. Five different types of amyloidosis have been described according to the underlying disease; immunoglobulin amyloidosis, familial amyloidosis, senile systemic amyloidosis, secondary amyloidosis and hemodialysis-associa...

There are several modalities for the treatment of the overactive bladder (OAB), but the results may not be satisfactory. A recent study has demonstrated that the OAB has a dysrhythmic electric activity that seems to result from a disordered vesical pacemaker. We hypothesized that vesical pacing may correct the irregularities of the vesical electric waves and consequently normalize the vesical c...

pounds administered into the caudal vesical arteries were investigated under blood perfusion at a constant rate. TEA, physostigmine, phenylephrine, 5hydroxytryptamine, angiotensin II, lys-vasopressin, oxytocin and ergotamine caused a contraction of the bladder and constriction of the vesical vascular bed. Acetylcholine, bethanechol, carbachol, TMA, lobeline, nicotine, DMPP, neostig mine, histam...

Electric signals from a chest skin electrode can be conducted to the heart and activate contraction. In the present study, normal and diabetic rabbits were stimulated by skin electrode on the abnormal bladder projection area using three levels of exporting voltage (5.84 V, 8.00 V, and 11.00 V). Results demonstrated significantly attenuated electric signals from both groups, in particular the di...
