| The influence of chronic nitric oxide synthase inhibition with N G-nitro-L-arginine methyl ester (L-NAME) on body fluid distribution was studied in male Wistar rats weighing 260-340 g. Extracellular, interstitial and intracellular spaces, as well as plasma volume were measured after a three-week treatment with L-NAME (~70 mg/kg per 24 h in drinking water). An increase in extracellular space (16.1 ± 1.1 vs 13.7 ± 0.6 ml/100 g in control group, N = 12, P<0.01), interstitial space (14.0 ± 0.9 vs 9.7 ± 0.6 ml/100 g in control group, P<0.001) and total water (68.7 ± 3.9 vs 59.0 ± 2.9 ml/100 g, P<0.001) was observed in the L-NAME group (N = 8). Plasma volume was lower in L-NAME-treated rats (2.8 ± 0.2 ml/100 g) than in the control group (3.6 ± 0.1... |

| Solution reflux and edema hamper the convection-enhanced delivery of the standard treatment for glioma. Therefore, a real-time magnetic resonance imaging (MRI) method was developed to monitor the dosing process, but a quantitative analysis of local diffusion and clearance parameters has not been assessed. The objective of this study was to compare diffusion into the extracellular space (ECS) at different stages of rat C6 gliomas, and analyze the effects of the extracellular matrix (ECM) on the diffusion process. At 10 and 20 days, after successful glioma modeling, gadolinium-diethylenetriamine pentaacetic acid (Gd-DTPA) was introduced into the ECS of rat C6 gliomas. Diffusion parameters and half-life of the reagent were then detected using MRI, and... |
