Correlation between hydrolysis of the -lactam bond of the cephalosporin nucleus and expulsion of the 3-substituent.

The hydrolysis of two cephalosporins by three different beta-lactamases has been studied. Each enzyme caused a decrease in ultraviolet absorption, a loss of biological activity, and the release of the leaving group from the 3-position. The changes occurred at the same rate and to the same extent with each enzyme, and it is inferred that the loss of the leaving group is a consequence of, and not a prerequisite for, hydrolysis of the beta-lactam ring.

Relationship between breathlessness and anxiety in asthma and bronchitis: a comparative study.

Two personality testing forms, the Eysenck Personality Inventory Form A and the Cattell Self Analysis Form, were completed on 471 hospital patients who fell within the general diagnostic range of asthma, bronchitis, or both. Respiratory diagnoses were based on the standard M.R.C. questionary. All categories of patients showed a tendency towards neuroticism, anxiety, and introversion, and the scores were slightly higher for bronchitics than for asthmatics. Neuroticism and anxiety increased with increasing respiratory disability. Variations in these scores with age of onset of symptoms and length of history were small.
