Clinical evaluation on 5 years' experience of automated phonocardiographic analysis.

A mini-computer system for PCG interpretation has been functioning since 1971. The system can analyze as many as 100 PCG's in 3 hours. Based on our 5 years' experience, computer interpretation of PCG's has proved itself valuable for the rapid mass-screening of cardiovascular disease. It also provides more objective and quantitative information than human auscultation, though it is still at a developmental stage because of the present technical limitations. The solution of these shortcomings should achieve an automated PCG analysis of high accuracy.

Genetic mapping of the locus for detergent-resistant phospholipase A(pldA) in Escherichia coli K-12.

An Escherichia coli K-12 mutant deficient for detergent-resistant (DR) phospholipase A, a principal enzyme catalyzing the first step in phospholipid degradation, was characterized genetically. The mutation was found to affect the locus pldA (phospholipid degradation), which is cotransducible both with ilv and metE at a frequencies of 13 and 78%, respectively, and shown to lie between the ilv and metE loci on the E. coli chromosome. DR phospholipase A(1) and A(2) activities were simultaneously transduced with pldA(+) by phage P1; therefore it is proposed that DR phospholipase A has both activities.
