Hydrogen Ion Concentration and Acid-base Equilibrium in Normal Pregnancy
In 1912 Hasselbalch, with Lundsgaard and Gammeltoft (6, 7), described a lowering of the alveolar carbon dioxide and of the carbon dioxide-combining power of the blood in the later months of normal pregnancy. These changes have been abundantly confirmed by others and found to appear early in the course of pregnancy. These findings together with an increased ammonia to total nitrogen ratio in the...
متن کاملThe Formation of Methemoglobin by Streptococcus Viridans
Cultures of Streptococcus viridans when brought into contact with red blood corpuscles have the power of transforming oxyhemoglobin into methemoglobin. The reaction occurs only in the presence of living streptococci when they are able to carry on their metabolic activities. The intensity of the reaction runs roughly parallel with the period of growth and multiplication of the bacteria and gradu...
متن کاملPrimary Streptococcus viridans pneumonia.
We describe three cases of acute uncomplicated bacterial pneumonia due to viridans streptococci in previously healthy adults, which were indistinguishable from those caused by other well-known respiratory pathogens. On arrival, all of these patients were treated with IV aqueous penicillin based on Gram stain of sputum which showed predominant Gram-positive cocci in pairs and chains. These speci...
متن کاملHydrogen pair-ion production by catalytic ionization
Pair plasmas consisting of only positiveand negative-charge particles of equal mass have attracted special attention because they maintain space-time symmetry. A fullerene pair-ion plasma, consisting of positive and negative ions of equal mass (C60 and C60), has been generated and its collective phenomena have been investigated experimentally [1]. In order to investigate more extensive physical...
متن کاملThe Localization of Streptococcus Viridans
The results of our experiments do not substantiate in full the theory of the power of selective action of Streptococcus viridans. A few strains showed a remarkable constancy in location and type of lesion, but these strains were greatly in the minority. The location of the lesions in animals seemed to bear no relation to the origin of the organism or to the lesions produced by it in the patient...
