    Relationship between clinical symptoms of anal incontinence and the results of anorectal manometry (1992)
    Springer
    Diseases of the colon & rectum 35 (1992), S. 847-849

    Notes: Abstract The aim of this work was to analyze clinical symptoms in light of anorectal manometry results. We compared the frequency of clinical symptoms in relation with the presence or absence of functional anomalies. Using this methodology, the following relationships may be suggested: the need to wear a pad, with a decreased resting pressure at the upper part of the anal canal; the inability to delay rectal evacuation, with decreased anal voluntary contraction; interference of incontinence with social activities, with decreased duration of anal voluntary contraction; urinary symptoms, with an increased threshold volume of rectal distention needed to elicit the rectoanal inhibitory reflex; and complete rectal prolapse, with reduced length of the anal canal.

    The spatial distribution of cations in nematocytes of Hydra vulgaris (1991)
    Springer
    Hydrobiologia 216-217 (1991), S. 661-669 
    Details
    ISSN: 1573-5117
    Keywords: Hydra vulgaris ; nematocysts ; potassium

    Topics: Biology
    Notes: Abstract The spatial distribution of cations was assayed qualitatively and quantitatively in tentacular nematocytes of Hydra vulgaris in a scanning transmission electron microscope by means of x-ray microanalysis performed on 100 nm thick freeze-dried cryosections. The matrix of undischarged cysts (stenoteles, desmonemes and isorhizas) was found to contain mainly K+. In isolated nematocysts of Hydra the intracapsular potassium can be readily substituted by practically any other mono- and divalent cation (Na+, NH4 +, Mn2+, Co2+, Mg2+, Ca2+, Fe2+) all, except Fe2+, without impairing the ability of the cyst to respond to the chemical triggering with dithioerythritol or proteases. Monovalent cations increase the osmotically generated intracapsular pressure compared to divalent ions.
