Urinary bladder function in conscious rat pups: a developmental study.
Cystometric studies of bladder function in anesthetized neonatal rats have suggested specific changes in urodynamic parameters that coincide with the development of a mature bladder-to-bladder micturition reflex. Here, we used a conscious cystometry model that avoids the potentially confounding effects of anesthesia to characterize voiding patterns and urodynamic parameters during early postnat...
متن کاملRhythmic Calcium Events in the Lamina Propria Network of the Urinary Bladder of Rat Pups
The lamina propria contains a dense network of cells, including interstitial cells (ICs), that may play a role in bladder function by modulating communication between urothelium, nerve fibers and smooth muscle or acting as pacemakers. Transient receptor potential vanilloid 4 (TRPV4) channels allow cation influx and may be involved in sensing stretch or chemical irritation in urinary bladder. Ur...
متن کاملDevelopmental changes in spontaneous smooth muscle activity in the neonatal rat urinary bladder.
Changes in spontaneous activity of the urinary bladder during postnatal development were examined in muscle strips from the base and dome of bladders from 1- to 5-wk-old rats. Activity was analyzed using fast Fourier transformation (FFT), nonlinear cross prediction, and the Shannon entropy test. Spontaneous activity was not detected in strips from 1- to 5-day-old rats but was observed in 50% of...
متن کاملThe Sheep’s Urinary Bladder Matrix as a Potent Biological Materials Resource -an Ultrastructural Study
Background and Objectives: Biological scaffold resources composed of extracellular matrix (ECM) have been shown to make easy the practical remodeling of various tissues in both animal and human studies. The goal of current study was to make sheet form of ECM from sheep’s urinary bladder. Methods: ECM was extracted from Sheep’s urinary bladder according to standard method. Scanning electron ...
متن کاملAcrolein initiates rat urinary bladder carcinogenesis.
Acrolein, a reactive, alpha,beta-unsaturated aldehyde which is ubiquitous in the environment, forms DNA adducts, is mutagenic, and is teratogenic. However, studies have not indicated a carcinogenic effect in rodent bioassays. Since it is present in cigarette smoke and is the toxic metabolite of cyclophosphamide with respect to the urinary tract, we investigated the possibility that acrolein mig...
