AIM:To evaluate lipid profile in children with coronary artery disease(CAD)in Hyderabad,Sindh,***:The study included 100 children(6-15years),of which 43 were children of young parents(one or both)with recognized CAD,while the other 57 were children with no evidence of CAD(controls).All were evaluated for fasting blood lipid *** samples were collected from patients with CAD and healthy controls and analysis of the levels of lipid profile were carried out using a kit method on Microlab ***:Children with CAD had significantly higher levels of total serum cholesterol and triglycerides and decreased levels of high density lipoprotein and low density lipoprotein compared to children in the control *** and diastolic blood pressures were significantly higher,without any significant ***:CAD risk factors are significant regarding abnormal lipid *** tendency seems to be important in the development of CAD in children.

SOLVENT QUaliTY AND SOLUTION BEHAVIOR OF NYLON 12

引用

Chinese Journal of Polymer Science 2007年第5期25卷 483-490页

The refractive index increment, dynamic and static laser light scattering, intrinsic viscosity [η] and Huggins constant （KH） of nylon 12 have been measured in m-cresol and sulphuric acid/water system at 10-60℃. The intrinsic viscosity, Rn, Rg, A2, and （〈 S 〉2）^1/2 （calculated from viscosity data） and ＂a＂ values of nylon 12 are found to be higher in m-cresol than in sulphuric acid. All these parameters decrease with the increase in water contents in sulphuric acid. The refractive index increment, KH and activation energy show an opposite trend to that of [η]. The intrinsic viscosity, RH, Rg, A2, and （〈 S 〉2）^1/2 have maximum values around 30-40℃ in sulphuric acid/water system, whereas in m-cresol they fall at about 20℃. It has been concluded that the variation in size, interaction parameter （second virial coefficient）, [η] and KH of the polymer solutions with the alteration in solvent composition and temperature are the out come of change in thermodynamic quality of solvents, selective adsorption, hydrogen bonding and conformational transitions. It has also been concluded that the increase in temperature first enhances the quality of the solvent, encourages hydrogen bonding and specific adsorption, and then deteriorates, bringing conformational transitions in the polymer molecules. However, the addition of water to sulphuric acid continuously deteriorates the solvent quality. This characteristic of the solvent system brings conformational changes in the polymer especially at low temperatures.
