  • (19) We have investigated the effect of methimazole (MMI) on cell-mediated immunity and ascertained the mechanisms of immunosuppression produced by the drug.
  • (20) Apparently, the irradiation with visible light of a low intensity creates an additional proton gradient and thus stimulates a new replication and division cycle in the population of cells whose membranes do not have delta pH necessary for the initiation of these processes.

Protoplasm


Definition:

  • (n.) The viscid and more or less granular material of vegetable and animal cells, possessed of vital properties by which the processes of nutrition, secretion, and growth go forward; the so-called " physical basis of life;" the original cell substance, cytoplasm, cytoblastema, bioplasm sarcode, etc.

Example Sentences:

  • (1) Fixation with buffered glutaraldehyde resulted in higher counts (P less than 0.01) of proximal protoplasmic droplets (2.47, 1.03, 0.67, and 1.43%, respectively, for glutaraldehyde, Hancock's, Blom's, and formol saline procedures).

  • (3) Protoplasmic cylinders contained within such granules frequently were devoid of cell envelopes.
  • (4) The infected cells treated by this method showed light green fluorescence of the protoplasm, with a dark nucleus, while the intact cells had tile-red cytoplasm.
  • (5) That T-tubules isolated by disruption of triad junctions are constrained to have the protoplasmic (P) face uniformly exposed was experimentally confirmed.
  • (6) The morphological change of cerebral cortex astrocytes from protoplasmic to glial fibrillary acidic protein (GFAP)-containing cells is induced by injury.
  • (7) Pretreatment of mice by intravenous injection with killed Listeria provided neither delayed-type hypersensitivity to Listeria protoplasm nor protection against Listeria infection.
  • (8) The greatest motion of protoplasmic droplets was recorded in the caput epididymidis, although the migration of droplets from the proximal section of the connective part of the flagellum towards the distal parts could also be observed as far as in the cauda epididymidis in both animals.
  • (9) Thus staining techniques that have a propensity for the glial filaments such as antisera to glial fibrillary acidic protein and the gold-chloride method provide only a skeletal outline of the major processes of the protoplasmic astrocyte.
