Both deficiencies create problems in fields, such as laboratory medicine, which have to report results of all types of property, preferably in a unified systematic format. The present text aims at forming a domain ontology around \"property\", with intensional definitions and systematic terms, mainly using the terminological tools--with some additions--provided by the International Standards ISO 704, 1087-1, and 10241. \"System\" and \"component\" are defined, \"quantity\" is discussed, and the generic concept \"property\" is given as 'inherent state- or process-descriptive feature of a system including any pertinent components'. Previously, the term 'kind-of-quantity' and quasi-synonyms have been used as primitives; the proposed definition of \"kind-of-property\" is 'common defining aspect of mutually comparable properties'. \"Examination procedure\", \"examination method\", \"examination principle\", and \"examination\" are defined, avoiding the term 'test'. The need to distinguish between instances of \"characteristic\", \"property\", \"type of characteristic\", \"kind-of-property\", and \"property value\" is emphasized; the latter is defined together with \"property value scale\". These fundamental concepts are presented in a diagram, and the effect of adding essential characteristics to give expanded definitions is exemplified. Substitution usually leads to unwieldy definitions, but reveals circularity as does exhaustive consecutive listing of defining concepts. The top concept may be generically divided according to many terminological dimensions, especially regarding which operators are allowed among the four sets =, not equal to; <, >; +, -; and x, :. The coordinate concepts defined are termed by the modifiers 'nominal', 'ordinal', 'differential', and 'rational' before '...property'. Other possibilities are given, based on the literature, especially the stepwise division into \"nominal property\" and \"quantity\"; \"ordinal quantity\" and \"unitary quantity\"; \"differential unitary quantity\" and \"rational unitary quantity\". As top concepts, , , , , and are i.a. divided homologously to . The term 'observation' and the modifiers 'qualitative', 'semi-quantitative', and 'quantitative' are avoided. \"Metrological unit\" and \"system of metrological units\" are defined together with a number of specific concepts. Some problems with characteristics of \"SI unit\" are discussed and an alternative system shown. The conceptions of \"metrological dimension\" are outlined, leading to a definition and specific concepts.

A granulation tissue is produced following incision of tissue such as skin, abdominal wall or the gastrointestinal tract, and the strength of the wound is determined primarily by the collagen content early in the healing course. Few models are available to study wound healing in man. The percutaneous insertion of expanded poly-tetrafluoroethylene tubes (ePTFE) into the subcutaneous tissue has been an established model for 20 years. The procedure is performed using a local anesthesia. The model has a diameter of 2.5 mm, a length of 5-10 cm and a pore size of 90-120 microns which is substantially more than that of vascular grafts. The polymer accumulates granulation tissue, the architecture of which resembles that of a normal surgical wound. Previous studies on the use of the ePTFE model in wound healing research are summarized in detail. Histological and immunohistochemical analyses of the granulation tissue deposited in the model were undertaken. The content of amino acids following hydrolysis of the granulation tissue was determined applying spectrophotometric or HPLC assays. Collagen amounts accumulated in the model are expressed as hydroxyproline per length of ePTFE or per total protein. Following a study in rats we examined 85 healthy volunteers and 158 surgical patients in the studies. Higher contents of hydroxyproline were found 10 days after implantation as compared to 5 days with considerable inter-person variation. Regarding median values there was a 25% difference between two measurements performed on two distinct ePTFE tubes from the same person, and a 12% difference between values obtained from two different pieces of the same ePTFE. Higher accumulation levels of hydroxyproline did not result in higher variability. Deposition of proline in the model correlated closely to total protein content. The ePTFE and a modified PVA model were compared in surgical patients. No reproducible measurements of hydroxyproline deposition were obtained with the PVA model as opposed to the ePTFE model. It is concluded that the modified PVA model is inadequate for determination of collagen deposition in subcutaneous granulation tissue. We found no correlation between collagen deposition levels obtained with placement of the ePTFE model in the subcutaneous tissue of the arm and in an uncomplicated surgical wound of the groin in the same patient, respectively. Significantly higher collagen deposition levels in the model were found in the surgical wound. Conversely, there was a significant correlation between protein deposition levels obtained at the two sites. Patients undergoing minor surgery (groin hernia repair) did not differ from healthy non-traumatized volunteers as regards deposition of collagen in subcutaneous tissue of the arm, whereas patients subjected to major general surgery demonstrated a significant decline duri","PeriodicalId":77006,"journal":{"name":"APMIS.

Mechanism of antibiotic resistance and target of the humoral immune response.","authors":"Oana Ciofu","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>The intensive antibiotic treatment of cystic fibrosis (CF) patients with chronic lung infection with Pseudomonas aeruginosa has improved the survival rate and the clinical condition of Danish patients. Acquirement of resistance to anti-pseudomonal antibiotics is one of the main drawbacks of this therapeutic strategy and our results showed the development of resistance of P. aeruginosa to several antibiotics during 25 years of intensive antibiotic treatment. Our studies have been concentrating on the development of resistance to beta-lactam antibiotics. We have shown an association between the development of resistance to beta-lactam antibiotics and the occurrence of high beta-lactamase producing strains and between the MIC of the beta-lactams and the levels of beta-lactamase expression. Partially derepressed mutants, characterized by high basal levels of beta-lactamase with the possibility of induction to even higher levels during treatment with beta-lactam antibiotics, were the most frequent phenotype found among resistant Danish P. aeruginosa CF isolates. We have also shown that the high alginate producing P. aeruginosa isolates, that characterize the chronic lung infection in CF patients, are more susceptible to antibiotics and produce less beta-lactamase than the non-mucoid paired isolates. We propose that the non-mucoid isolates are exposed to a relatively higher antibiotic pressure than the mucoid isolates and therefore, they become easily antibiotic resistant and in consequence produce high levels of beta-lactamase. The beta-lactamase produced by the non-mucoid isolates might play a protective role in the biofilm, defending the mucoid isolates from the action of beta-lactam antibiotics and helping them to maintain their antibiotic susceptibility. We have also shown that beta-lactamase, which is a periplasmic enzyme, can be secreted extracellulary packed in membrane vesicles liberated by high beta-lactamase-producing P. aeruginosa. The continuos presence in the CF lungs of bacteria producing high basal levels of beta-lactamase (partial derepressed) induces a humoral immune response to beta-lactamase. We have shown that antibodies against the chromosomally encoded beta-lactamase (a beta ab) might be considered a marker of the development of resistance to beta-lactam antibiotics. We investigated the humoral immune response to beta-lactamase by quantifying a beta ab specific IgG and IgG subclass antibodies, by investigating the influence of the allotypes on the IgG subclass response and by measuring the avidity of the IgG a beta ab. We found that CF patients with good lung function had in the early stages of the chronic lung infection higher titers of a beta ab of good avidity than patients with poor lung function. Therefore, we raised the hypothesis that some of the a beta ab might have beta-lactamase neutralizing effect, playing a beta-lactamase inhibitor role and improving the effect of the treatment with beta-lactam antibiotics.

Ongoing studies suggest that recording of bladder nerve activity is stable over time and may be a technique for chronic monitoring of bladder activity. Bladder emptying exploiting an anodal blocking technique permits bladder emptying without simultaneous urethral-perineal contraction, thus enabling a physiological voiding pattern in one continuous sequence. In patients with supraspinal lesions, deep brain electrical stimulation is established only as treatment for a subgroup of patients suffering from Parkinson's disease. Yet, with improved electrode designs and increased clinical experience and experimental results, probably other groups of patients may be candidates for deep brain stimulation.

A clinico-pathological, immunohistological, and DNA ploidy study.","authors":"Gyda Lolk Ottesen","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Carcinoma in situ of the breast (CIS) comprise a heterogenous group of lesions, covering a wide spectrum of clinical conditions and histopathological changes. With respect to biological behavior, CIS range from biologically aggressive lesions with a substantial risk of progression into invasive carcinoma (IC), to lesions with a very low malignant potential. Two main types of CIS are described--ductal carcinoma in situ (DCIS) and lobular carcinoma in situ (LCIS). Previous studies of CIS indicate that approximately a third will subsequently develop IC. Autopsy studies indicate that CIS is frequently occurring and it was estimated that about 20% of all women will develop CIS during lifetime. Only a minor fraction is ever diagnosed, although the incidence of DCIS is increasing, especially related to mammography screening. The lack of knowledge about the biological significance of the histopathological subtypes was the background of the present study. In 1982, a nationwide, prospective study of CIS (protocol DBCG 82-IS) was initiated by the Danish Breast Cancer Cooperative Group (DBCG). From this protocol, the group of patients treated with breast conservation surgery (BCS) constituted the material for clinico-histological investigation. A total of 275 women were included in the period 1982-89. Follow-up studies showed that recurrence rate was significantly related to nuclear size of the primary lesion. Since nuclear changes might be related to DNA content and, furthermore, many invasive breast carcinomas were shown to be DNA aneuploid, flow cytometric (FCM) DNA ploidy analysis was performed in a series of DCIS lesions. More than 80% of these lesions were DNA aneuploid, with a distribution similar to that found in invasive carcinomas. This finding raised the hypothesis that the DNA pattern of an invasive carcinoma was already established at the preinvasive stage of DCIS. Therefore, FCM DNA analysis was performed on a series of ICs with predominance of DCIS. Partial or complete concordance in DNA ploidy between DCIS and IC within the individual case was found in most cases, except for the additional presence in the IC component of DNA hyperdiploid clones that might possibly be of importance for the process of invasion. In order to further characterize CIS lesions and, possibly, to discriminate biologically different groups, immunohistochemical markers were investigated in a consecutive series of CIS and IC with predominance of DCIS. The results were correlated to the histopathological and DNA ploidy findings. In DCIS, significant correlation was shown between large nuclear size and comedonecrosis, both of which showed also strong association to DNA aneuploidy, high proliferation activity, low steroid receptor content, and overexpression of c-erbB-2 and p53--factors that may indicate an aggressive behavior. Small nuclear CIS, whether LCIS or DCIS, on the contrary, were DNA diploid with low proliferation, and no cases showed overexpression of c-erb","PeriodicalId":77006,"journal":{"name":"APMIS.
