(18) In some areas, the tumor shows a striking resemblance to Kaposi's sarcoma; criss-crossing fascicles of spindle cells are interspersed with narrow vascular spaces, but PAS-positive hyaline globules are absent.
(19) Within the PGE2-protected animals a significant increase was observed in the length of zones of the mucus-producing cells at the surface and in the foveolae (both PAS-positive and alcian-blue-positive cells).
(20) Serous granules were stained by toluidine blue, or by hematoxylin and eosin (H and E), but showed little or no reaction with periodic acid-Schiff (PAS) or Alcian blue.
Vas
Definition:
(n.) A vessel; a duct.
Example Sentences:

(3) At a concentration of 10 microM, tetraamine 4 did not affect histamine and 5-hydroxytryptamine receptors of guinea pig ileum or alpha-adrenoreceptors of guinea pig atria whereas it inhibited postsynaptic alpha-adrenoreceptors of rat vas deferens with a -log K value of 5.23 and nicotinic receptors of frog rectus abdominis with an IC50 value of 0.23 microM.
(4) Emphasis is placed on techniques that prevent spontaneous recanalization of the ends of the vas deferens after vasectomy.
(5) After properly fixing the vas deferens with a ring clamp, the surgeon pierces the scrotal skin, vas sheath, and vas deferens in the midline with a curved dissecting clamp held at a 45 degree angle from horizontal.
(6) The acrosin inhibitors are localized in the mucosa cells of the cauda epididymis, the vas deferens, the seminal vesicles, the urethra and distinct glandular units of the prostate.

(9) There was a significant positive correlation between the efflux of noradrenaline from platelets and vas deferens (r = 0.56, P less than 0.001).
(10) Supersensitivity to noradrenaline was produced by both of the stereoisomers in isolated vas deferens of guinea-pigs although there was no difference in the activity.

(12) Probably there is a continuity of this system throughout the entire vascular pole including (1) all granulated cells, (2) all lacis cells, (3) the mesangium cells and (4) the adjacent smooth muscle cells of the vas afferens and vas efferens.
(13) Pain scores (VAS) and responses to a pain questionnaire were similar for both groups; however, within Group B improvement in mean VAS scores at rest with time were more sustained.
(14) Various techniques have been described, but in this surgeon's opinion the simplest and best method is to remove a length of a vas such that it becomes a physical impossibility to approximate the cut ends.
