Patients with chronic hepatitis B have antibodies against hepatitis B, but these antibodies are not enough to clear the infection of the affected liver cells. The continued production of virus combined with antibodies is a likely cause of the immune complex disease seen in these patients.
1 Hydrolytic Degradation: ï This process occurs in polymers that are watersensitive active groups, especially those that take a lot of moisture. ï 2  Polymers that have an ability for hydrolytic destruction usually have heteroatoms in the main or side chain. Mechanism of Hydrolytic Degradation ï Hydrolytic degradation of members of the polylactide/glycolide family proceeds through four stages as represented in Figure 2: First stage of water diffusion followed by second stage, in which oligomers with acidic endgroups autocatalyze the hydrolysis reaction.
Hydronephrosis is the swelling of a kidney due to a build-up of urine. It happens when urine cannot drain out from the kidney to the bladder from a blockage or obstruction. Hydronephrosis can occur in one or both kidneys. The main function of the urinary tract is to remove wastes and fluid from the body.
