Numerical data concerning the sensitivity of anaerobic bacteria to oxygen.

Upon comparison of results obtained from growing eight different species of anaerobic bacteria in deep agar under two and three atm of pure oxygen with results of growing them in air under atomospheric pressure, it appears possible that the old terms of "microaerophobic," "very strict anaerobe," and "microaerophilic" can be replaced by precise values corresponding to the size of the inhibition zone produced by oxygen under various pressures when the bacteria are grown in a solid medium. The simultaneous effect of the dilution of the inoculum and the pressure of oxygen used was determined with the help of an electronic computer according to the standard multiple regression method. Two indices have been worked out which express the sensitivity of the species at different oxygen pressures when varying numbers of anaerobic bacteria are used: X sp, which is the size in millimeters of the inhibition zone when 1:10 dilutions of the culture are grown under pure oxygen at atmospheric pressure (lp=0), and B sp, which is the result of multiplying by 1.43 the difference in size of inhibition zone when 1:10 dilutions of the culture are grown under atmospheric air (lp = -0.7) and under pure oxygen at 1 atm absolute.

Spiritual conflicts associated with praying about cancer.

A secondary analysis of data from a study designed to describe how persons use prayer to cope with cancer is presented in this paper to illuminate the spiritual conflicts that can be experienced among persons with cancer. Employing phenomenological methods, 30 persons from various phases of the cancer experience and religious backgrounds, were interviewed in depth about why, when, and how they prayed, as well as what they prayed about and the outcomes they expected. The secondary analysis revealed that many of these informants had hesitancies about petitionary prayers for particular things, a cure, or for themselves. They also indicated questions about theodicy and the meaning of having cancer, the nature of God, and acknowledged 'unanswered' prayer. Several described an inner conflict about releasing control to God. A few referred to bargaining with God, and a few doubted their personal spirituality and worth, if they were praying correctly, and if prayer was efficacious.

Neonatal candidemia.

Fifty five clinically diagnosed cases of neonatal septicaemia of the nursery ward, Medical College Hospital Calcutta were subjected to blood culture on two consecutive days in all cases. Bacterial isolates were found in 34 (61.8%) cases as pure growth and candida species from 9 (16.4%) as pure culture. Remaining 12 samples did not yield any growth. Species distribution of candida showed C. albicans 6, C. parapsilosis 2, and C. guillermondii 1. Asphyxia neonatorum was the common feature in all cases of candidaemia. All neonates with candidal infection were low-birth-weight and premature. C. albicans, the predominant species (66.6%) recovered, was responsible for a localised outbreak of infection in the nursery.
