The Extracellular Relation of the Malarial Parasite to the Red Corpuscle, and Its Method of Securing Attachment to the External Surface of the Red Corpuscle
Laveran ( I ) has consistently claimed f rom the beginning that the parasites were extracellular and that they attached themselves to the surface of the red corpuscles, adhering to them " b y pressing on them." Richard (2) thought at one time that the parasites were within the substance of the red corpuscle; but later (3) he returned to Laveran 's opinion that they were attached to the surface....
متن کاملA Stage in the Migration of the Adult Tertian Malarial Parasite. Evidence of the Extracellular Relation of the Parasite to the Red Corpuscle
1. What appear to be certain definite stages in the migration of the malarial parasite from red corpuscle to red corpuscle may be demonstrated by thorough and persistent observations,-not minutes spent on each specimen, but many hours. 2. The migration of the malarial parasite from red corpuscle to red corpuscle gives a reasonable explanation of the loss of red corpuscles which cannot be accoun...
متن کاملComparative evaluation of fifteen anti-sickling agents.
Fifteen compounds reported to be inhibitors of gelation or sickling were studied by standard methods. These tests included (1) the determination of the solubility of deoxyhemoglobin S or Csat, (2) evaluation of sickling in whole SS blood at various pO2s, (3) measurement of the oxygen affinity of hemoglobin and blood, and (4) examination of red cell indices and morphology. Among the 4 noncovalen...
متن کاملThe Formation of Macrocytes and Microcytes from Red Corpuscles in Hanging Drop Preparations
IN HANGING DROP PREPARATIONS OF NORMAL BLOOD FROM VARIOUS SPECIES OF ANIMALS INCLUDING MAN, THE FOLLOWING PROCESSES WERE DIRECTLY OBSERVED FOR THE FIRST TIME: 1. The process of fusion between two red corpuscles so as to form a round or slightly oval macrocyte with normal hemoglobin content, a diameter of 10micro+/- and no delle. These macrocytes appear to be slightly thicker in the centre than ...
متن کاملIn vivo red blood cell sickling and mechanism of recovery in whiting, Merlangius merlangus.
Haemoglobin concentrations in vertebrate red blood cells are so high that in human sickle cell disease a single surface amino acid mutation can result in formation of large insoluble haemoglobin aggregates at low oxygen levels, causing peculiar cell deformations or 'sickling'. This may cause vascular occlusion and thereby severe pain, organ failure and death. Here, using light and transmission ...
