(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.
Pus
Definition:
(a.) The yellowish white opaque creamy matter produced by the process of suppuration. It consists of innumerable white nucleated cells floating in a clear liquid.
Example Sentences:
(1) It is concluded that ultrasonography, 67Ga scanning, and CT each have significant limits in diagnosing intra-abdominal pus.
(2) It is important that the nurse recognize when pus is a major factor in an unhealed wound and initiate local care to assist in cleaning the wound bed.
(3) Confirmation of diagnosis was established by exteriorization of pus with US, CT or during surgery.
(4) We isolated a strain of P. penneri from the pus of a patient with suppurative otitis media and an epidural abscess on June 10 and 15, 1989.
(5) Furthermore, useful antibacterial concentrations of both drugs were found in pus, sputum, and middle-ear fluid.
(6) The surgeons were able to aspirate the accumulated pus quite easily in 8 of the 9 patients with AIDS who underwent only intercostal drainage.
(7) Craniotomy disclosed an abscess containing yellow pus from which Streptococcus viridans was cultured.
(8) In the case of the suppurative reaction, pus drained along a root surface, destroying the periodontal ligament and interradicular bone until it emerged at the gingival sulcus.
(9) The final diagnosis was based on direct microscopy (2) or culture (1) of drained pus in the empyema cases and on histologic examination of resected tissue in the others.
(10) The mastoid cavity was found to be filled with pus and cholesteatoma debris.
(11) No macroscopic infection with pus formation occurred, while Micrococcus varians was cultured from each inoculated implant.
(12) When distribution of these organisms were classified depending on clinical materials from which they were isolated, outpatient sources from which S. aureus were isolated at high frequencies were otorrhea and pus, while inpatient sources with high incidents of S. aureus isolation were sputum and pus.
(13) No viability loss of B. fragilis was noted when pus was stored at 25 degrees C. Only slight loss of viaability of B. fragilis was observed at 15 degrees C. Escherichia coli coexisting in pus with B. fragilis increased several 100fold in 24 h when stored at 25 degrees C, but no significant growth occurred when they were kept at 15 degrees C. Approximately 20 to 40% of E. coli lost their viability when such pus was stored at 4 degrees C. We suggest that 15 degrees C may be an alternative temperature for storage of anaerobic specimens in laboratories where some delay in routine processing is unavoidable.
(14) The drug was not degraded by pus containing beta-lactamase and had equally good or better activity than nafcillin or vancomycin against Staphylococcus aureus or Staphylococcus epidermidis in vitro and in vivo.
