    Preventing IUCD-related pelvic infection: the efficacy of prophylactic doxycycline at insertion (1990)

    Notizen: Summary. Most of the small increased risk in pelvic inflammatory disease (PID) associated with the intrauterine contraceptive device (IUCD) appears to be caused by bacterial contamination of the endometrial cavity at the time of insertion. This randomized clinical trial of 1813 women in Nairobi, Kenya, assessed the effectiveness of 200 mg of doxycycline given orally at the time of insertion in reducing the occurrence of PID. The rate of this infection in the doxycycline-treated group was 31% lower than that in the placebo-treated group (1.3 and 1.9%, respectively; RR 0.69; 95% CI 0.32 to 1–5). The rate of an unplanned IUCD-related visit to the clinic was also 31% lower in the doxycycline-treated group (RR 0.69; 95% CI 0.52 to 0.91). Although the significance level (P = 0.17) for the reduction is PID does not meet the conventional standard of 0.05, the results may be suggestive of an effect. Moreover, the reduction in IUCD-related visits (P = 0.004) not only represents an important decrease in morbidity but also substantiates the reduction found for PID. Further studies are needed to corroborate these results. Consideration should be given to the prophylactic use of doxycycline at the time of IUCD insertion as an approach to preventing PID and other lUCD-related morbidity.

    Incidence of Vibrio vulnificus in northern New England water and shellfish (1990)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS microbiology letters 72 (1990), S. 0

    Thema: Biologie
    Notizen: Abstract Vibrio vulnificus, an autochthonous inhabitant of the estuarine environment, was detected in water and oysters from the Great Bay Estuary System of New Hampshire and Maine. Previously, it had not been detected north of Boston Harbor on the east coast of the United States. V. vulnificus was detected in water and shellfish samples at five out of ten sites, and only in areas that were not open to recreational shellfishing. Although samples were collected from May into December, V. sulnificus was only detected in shellfish in July and August. Water sampling began in August, and V. vulnificus persisted at one site into October.

    Caudate nucleus pathology in Parkinson's disease: ultrastructural and biochemical findings in biopsy material (1992)

    Notizen: Summary Ultrastructural and biochemical properties of caudate nucleus (CN) biopsies in two patients with advanced Parkinson's disease (PD) were compared with three CN specimens removed during surgery for intracranial tumors. An additional two specimens from neurologically intact patients (59 and 86 years old) were removed during autopsy (performed 3 and 4 h post mortem, respectively) for electron microscopic studies. Dopamine levels in PD were reduced to less than 15% of control values. Both PD patients showed frequent dystrophic neurites and transsynaptic degeneration of neurons and neuritic processes. These changes were not found in CN from the four control individuals. Only a few dystrophic neurites were noticed in one 67-year-old control patient. The development of neuroaxonal dystrophy in CN is consistent with a dying-back process, probably accompanying abnormalities of axonal transport in PD. Transsynaptic degeneration of neurons in CN very likely represents a morphological marker of disease severity. The occurrence of this change may account for the poor clinical response of patients with advanced PD to intracerebral implantation of dopaminergic tissues.

    Pharmacological characterization of WAY-121,520: A potent anti-inflammatory indomethacin-based inhibitor of 5-lipoxygenase (5-LO)/phospholipase A2 (PLA2) (1993)

    Notizen: Abstract WAY-121,520 inhibited human synovial fluid PLA2 (HSF-PLA2) (IC50=4 μM) using arachidonic acid-labeledE. coli as substrate. Further biochemical characterization of WAY-121,520 demonstrated potent inhibition of 5-lipoxygenase (5-LO) activity in the murine macrophage (LTC4, IC50=4nM) and rat PMN (LTB4, IC50=10 nM) and an ability to antagonize LTD4 binding to isolated guinea-pig trachea (pK B=6.0).In vivo anti-inflammatory activity was noted in murine TPA-induced (ED50=91 μg/ear) and arachidonic acid-induced (66% inhibition at 400 μg/ear) ear edema and in leukotriene-dependent antigen-induced bronchoconstriction in the guinea pig (73% inhibition at 50 mg/kg, p.o.). WAY-121,520 represents a novel series of indomethacin-based inhibitors of PLA2 with anti-inflammatory activity resulting from a combination of biochemical activities (inhibition of 5-LO and PLA2 and LTD4 antagonism). This agent may provide added therapeutic efficacy over more selective inhibitors.
