Study of the characteristics and some pharmaceutical aspects of homo and copolymers of vinyl alcohol

Degree of hydrolysis has a key role in the properties of polyvinyl alcohol and its copolymers. Degree of hydrolysis affects swelling, thermal behaviour as well as release of incorporated drugs. However, these properties are also affected by the composition of the copolymers and degree of crosslinking. Furthermore degree of swelling and drug release decreased by increasing the crystallinity in the copolymer

Relation of serum sialic acid with serum lipids in cardiac patients

Elevated serum sialic acid concentration is a risk factor for coronary heart disease in general population along with dyslipidemia. Sialic acid and lipid profile was determined in healthy subjects [Group A1 and A2] and sixty cardiac patients, divided into two groups, group B comprising of thirty male patients and group C comprising of thirty female patients. A highly significant increase was observed in the level of sialic acid and different variables of lipid profile except HDL-C in all patients. HDL-C showed a significant decrease in patients. An increase in the level of sialic acid in cardiac patients showing the implications of raised level of sialic acid in the development of cardiovascular complications
