| karyoplastin | The achromatic nuclear material that forms the spindle apparatus. (05 Mar 2000) |

| karyopyknosis | Cytologic characteristics of the superficial or cornified cells of stratified squamous epithelium in which there is shrinkage of the nuclei and condensation of the chromatin into structureless masses. Origin: karyo-+ G. Pyknos, thick, crowded, + -osis, condition (05 Mar 2000) |
| karyopyknotic | Pertaining to or causing karyopyknosis. (05 Mar 2000) |
| karyopyknotic index | An index used to monitor the hormonal status of the patient as reflected by exfoliated vaginal cells and their morphology; an expression of the percentage of intermediate and superficial cells from squamous cells of vaginal epithelium which have pyknotic nuclei. (05 Mar 2000) |
| karyorrhexis | <cell biology> Degeneration of the nucleus of a cell. There is contraction of the chromatin into small pieces, with obliteration of the nuclear boundary. (18 Nov 1997) |
| karyosome | <cell biology> The central portion of a cells nucleus that typically contains a glob of heterochromatin. Origin: Gr. Soma = body (09 Oct 1997) |
| karyostasis | Synonym: interphase. Origin: karyo-+ G. Stasis, a standing still (05 Mar 2000) |
| karyostenosis | <biology> Direct cell division (in which there is first a simple division of the nucleus, without any changes in its structure, followed by division of the protoplasm of the karyostenotic mode of nuclear division. Origin: NL, fr. Gr. A nut, kernel + a being straitened. Source: Websters Dictionary (01 Mar 1998) |
| karyotheca | Synonym: nuclear envelope. Origin: karyo-+ G. Theke, box, sheath (05 Mar 2000) |
| karyotype | <genetics> The complete set of chromosomes of a cell or organism. Used especially for the display prepared from photographs of mitotic chromosomes arranged in homologous pairs. (18 Nov 1997) |
| karyotypic abnormality | Abnormality in the number form or structure of chromosomes. Particular abnormalities are associated with particular sub- types of leukaemia. (27 Sep 1997) |
| karyotyping | Producing a karyotype for a cell or a cell line. (27 Sep 1997) |
| karyotyping, flow | Use of flow cytometry to analyze and/or separate chromosomes on the basis of their DNA content. Flow cytometry detects the light- absorbing or fluorescing properties of chromosomes passing in a narrow stream through a laser beam and with automated sorting devices can sort successive droplets of the stream into different fractions depending on the fluorescence emitted by each droplet. (12 Dec 1998) |
| karyozoic | Denoting a parasite inhabiting the cell nucleus of its host. Origin: karyo-+ G. Zoon, animal (05 Mar 2000) |
