An Investigation Of Some Changes In The Chemical Composition Of Arterial Tissue Which Correlate With The Development Of Arteriosclerosis, Richard Dee Strickland
An Investigation Of Some Changes In The Chemical Composition Of Arterial Tissue Which Correlate With The Development Of Arteriosclerosis, Richard Dee Strickland
Chemistry and Chemical Biology ETDs
Arteriosclerosis is one of the major health problems confronting people of middle and advanced age. The disorder, commonly called "hardening of the arteries", is a contributing factor in more deaths than any other ailment.
The profound alteration in the physical properties of arteries which comes about as a result of the sclerotic process suggests that equally important changes may take place in the chemical composition of the arterial tissue.

Recent work by Castle and Kruse (16) has partially elucidated the range of reactivity of the chlorine atom in the compounds 4-chlorocinnoline and 4-chloro-6,7-dimethoxycinnoline. Condensations between the chlorinated cinnolines and certain phenylacetonitriles were found to proceed readily; however, condensations with compounds of the malonic ester type were unsuccessful. It was found that hydrolysis of the condensation product obtained from 4-chlorocinnoline and phenylacetontrile by hot 60% sulfuric acid caused decarboxylation of the intermediate acid, the final product being 4-benzylcinnoline. This compound has a formal resemblance to the basic ring structure of papaverine.

The rare Earth elements, or lanthanides, having atomic numbers 57 through 71 occupy only one space in the periodic chart of the elements. These fifteen elements, which have extraordinarily similar chemical and physical properties, are placed in group three of the periodic table, between barium of group two and hafnium of group four. This series of elements has been the subject of extensive study in the past. The development of atomic energy has significantly increased the interest in the rare earths in the past ten years.
