  • (n.) A sort of pubescence, or a clothing of dense, curling hairs on the surface of certain plants.

Example Sentences:

  • (13) In parallel experiments, macrophages infected with the mycobacteria were co-cultured with syngeneic in vivo M. kansasii sensitized non-adherent, nylon-wool purified lymph node cells, and lymphoproliferation was measured by [3H]thymidine incorporation.
  • (14) "The Lib Dems are either cosmically ill-informed or seeking to pull the wool over the eyes of many thousands whose jobs depend on a thriving shipyard," he said.
  • (15) In general, IEL of satisfactory yield and of good viability were obtained with EDTA treatment of the gut tissues, followed by rapid passages of the resultant cells through nylon-wool columns and centrifugation on two-step Percoll density gradients (45% and 80%).
  • (16) There was a definite glove and stocking type of hypesthesia to pinprick and cotton wool.
  • (17) Since young nude mice could be rendered as unpermissive as older nude mice by pretreatment with either PNA-agglutinable thymus cells or nylon-wool passed spleen cells, it is suggested that an increased number of precursor T cells in older nude mice might induce this effect.
  • (18) Differences in wool production between ewes weaning one or two lambs were small.
  • (19) The effects of flumethasone on some aspects of wool growth revealed interactions between the routes of administration, the period of dosage and the rate of wool growth in the recipients.
