(16) Thus, it is possible to generalize from the present and earlier findings that amoeboid microglial cells are normal cellular constituents in the maturing central nervous system and their temporary existence in the neonatal stage indicates the necessity of these cells for subsequent maturation of the nervous tissue.
(17) Fifty-one patients were treated in a dual-centre, double-blind comparison of acyclovir and adenine arabinoside in herpetic amoeboid (geographic) corneal ulceration.
(18) Amoeboid chemotaxis involves a regulated increase in actin nucleation activity that is correlated with an increase in actin polymerization occurring seconds after chemotactic stimulation (Carson, M., Weber, A., and Zigmond, S. H. (1986) J.
(19) Some of the PGCs in contrast, did not enter the blood vessels but remained in the tissue (mesenchyme) of the embryo proper (tissue PGCs) and possessed pseudopodial processes, suggesting their migration by means of amoeboid movements.
(20) separation of hyaline plasma from granular plasma and changes in both the protoplasmic streaming pattern and locomotory activity of the cells, are discussed in terms of a general understanding of amoeboid movement.
Plasmodium
Definition:
(n.) A jellylike mass of free protoplasm, without any union of amoeboid cells, and endowed with life and power of motion.
(n.) A naked mobile mass of protoplasm, formed by the union of several amoebalike young, and constituting one of the stages in the life cycle of Mycetozoa and other low organisms.

(4) There was less of an increase following a blood meal infected with the rodent malaria parasite, Plasmodium berghei.
(5) Only gametocytes of the last species were found; they are similar to those of Plasmodium lemuris Huff and Hoogstraal, 1963.
(6) The animals were given Plasmodium bergheri-infected red blood cells 2 to 12 months after their initial inoculation with trypomastigotes of 3 different strains of Trypanosoma cruzi (Y. CL and Gilmar).
(7) On the basis of investigations of the malarial blood-stage antigens SERP, HRPII, and MSAI from Plasmodium falciparum, we chose two Escherichia coli-expressed hybrid proteins containing selected partial sequences of these antigens.
(8) An indirect fluorescent antibody test for glutaraldehyde-fixed, ring-infected erythrocyte surface antigen was performed on admission sera from 45 patients with complicated cerebral Plasmodium falciparum malaria, 33 with uncomplicated cerebral malaria, 91 non-cerebral malaria patients, and 53 blood donors from a non-malarious area.
