The efficacy of vaginal tablets (Gynoflor) containing 50 mg of a lyophilisate of viable, H2O2-producing Lactobacillus acidophilus (at least 10(7) colony forming units/tablet) and 0.03 mg estriol (CAS 50-27-1) for the treatment of bacterial vaginosis (BV) was tested in a multicentric, randomised, placebo-controlled clinical trial with parallel-group design.(More)
Human keratinocytes grown at an air-liquid interface on dead de-epidermalized dermis exhibit a pattern of organization similar to that seen in vivo. Cell renewal is limited to the basal layer. The cell cycle time determined after 7 days of culture, using a percentage labelled mitoses (PLM) technique, was about 15 h. This result is comparable with published(More)
Oral allergies are underdiagnosed by dental health professionals. Patients with an oral allergy complain of various symptoms such as burning or tingling sensations, with or without oral dryness or loss of taste, or of more general symptoms such as headache, dyspepsia, asthenia, arthralgia, myalgia. The signs of oral allergy include erythema, labial oedema(More)
Kaposi's sarcoma (KS) is an angioproliferative disease characterized by proliferating spindle-shaped cells, angiogenesis, and inflammatory cell infiltration. Several lines of evidence suggest that KS is a multifocal cytokine-mediated disease of vascular origin. Because metalloproteinases (MMPs) are important enzymes involved in angiogenesis, we studied(More)
A murine monoclonal antibody, FB1, reacted with the basal keratinocytes of human stratified epithelia. One-dimensional and two-dimensional immunoblotting assays, performed on keratins extracted from HaCat cells and normal human keratinocytes, showed that FB1 recognizes K14. When LL002, another K14 monoclonal antibody is added, the FB1 stained area in the(More)
Oral allergies represent a pathological entity not well known nor diagnosed by dental health professionals. The purpose of this work is to present an information relative to the multidisciplinary steps to be done to solve allergy problems. Three clinical examples of contact oral allergies (to mercury, or gold, or methacrylates) are presented, as to(More)
To approach the temporal relationship between alterations in keratinization and capillary leakiness in psoriasis, we studied the topography of these anomalies in spreading psoriatic lesions. Histological and immunohistochemical studies were performed on skin biopsies obtained from normal individuals and from psoriatic patients. In the latter case, biopsies(More)
The role of iron in the pathogenesis of several tumours is being increasingly investigated. In particular, its involvement in the pathogenesis of Kaposi's sarcoma (KS) is suggested by the distribution of the endemic form of KS corresponding to continental rifts and associated iron-oxide-rich volcanic clays. We investigated in vitro to what extent iron(More)
Whether Kaposi's sarcoma is a true neoplasm or a reactive endothelial cell outgrowth triggered by inflammatory cytokines remains unclear. In this study, we investigated the differential invasive properties of activated endothelial cells and Kaposi's sarcoma cells in a model of de-epidermized dermis, supplying the cells with matrix barriers similar to those(More)
