We examined a total of 150 samples, including 27 eye shadows, 27 mascaras and 96 face creams, for their microbial contents. Mascaras were generally more contaminated than eye shadows. More than 75% of the examined eye shadows contained fewer than 100 c.f.u./g aerobic bacterial count compared to 63% of the mascaras examined. Viable bacteria were not recovered from 61% and 48% of the eye shadows and mascaras respectively. While 4% of the eye shadows were heavily contaminated (contained more than 10(4) c.f.u./g), 15% of the mascaras were as heavily contaminated (with more than 10(4) c.f.u./ml of bacteria). Face creams were generally more heavily contaminated than eye shadows and mascaras. More than 70% of the examined creams contained more than 100 c.f.u./g of bacteria compared to 23% and 37% of eye shadows and mascaras respectively. Only 5% of the face creams were heavily contaminated. However, 27% of the creams were contaminated with more than 10(3)-10(4) c.f.u./g of bacteria compared to none in this range for both eye shadows and mascaras. Qualitative tests for detection of hazardous bacteria showed that none of the eye shadows were contaminated with any of those micro-organisms. Out of nine items of a specific brand of mascara, three isolates of Pseudomonas aeruginosa, one isolate of Citrobacter freundii and one isolate of Klebsiella pneumonia were detected. Among the creams, two brands showed the highest contamination levels with more than 85% of the tested samples containing more than 10(3) c.f.u./g fungi and at least 10(4) c.f.u./g bacteria.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

Proinflammatory cytokines and their corresponding receptor proteins in eccrine sweat glands in normal and cutaneous leishmaniasis human skin 总被引:1,自引:0,他引:1

Abstract Paraformaldehyde-fixed biopsy specimens of normal and chronic cutaneous leishmaniasis human skin were investigated for the presence and cellular distribution of interleukin-1α, interleukin-1β, interleukin-6 and tumour necrosis factor-α and the corresponding receptors in eccrine sweat glands, using an indirect immunoperoxidase technique. There was cytoplasmic staining for all 4 cytokines as well as their receptor proteins in the clear cells of the eccrine sweat glands of both normal and inflamed skin specimens. No staining could be seen in the dark cells or the myoepithelial cells, neither in normal nor in inflamed skin. However, a difference between normal and inflamed skin was observed in the ductal syslem. Thus, cell layers of the dermal ducts in leishmaniasis skin were stained for all 4 cytokines, with more intense labelling in the basal cell layer of the coiled ducts, while in the normal skin, an intense staining was more evident in the inner luminal layer, with variable and less intense labelling of the basal layer. The immunolabelling for the cytokine receptors within the dermal ducts exhibited similar staining intensity in both luminal and basal cell layers, except in the case of the IL-6 receptor, which showed a moderate to intense signal in the basal cell layer but a weak staining of the luminal cell layer. Infiltrating inflammatory cells around the sweat gland apparatus in leishmaniasis skin exhibited immunoreactivilies for all cylokines and their corresponding receptors. 相似文献

In three consecutive steps involving halogenation, amination, and condensation with a convenient acyl derivative ( 1 or 2 ), α-hydro-ω-hydroxypoly(oxyethylene) ( 3 ) was transformed into poly(oxyethylene)s 7 containing 0,6 to 1,3 mol of 3-[3,17β-dihydroxy-1,3,5(10)-estratrien-7α-yl]butyroyl end groups or 0,7 mol of 3-oxo-4-androsten-17β-ylcarboxyl end groups per mol of polymer. Applying the method of affinity partitioning, the former poly(oxyethylene) derivative 7 was used to purify successfully Δ5→4 3-oxosteriod isomerase contained in a crude extract from Pseudomonas Testosteroni. 相似文献

In order to analyze the current epidemiological pattern of mycobacterial infection in children in Central Tunisia, we studied retrospectively the clinical feature of 31 children with mycobacterial infection enrolled in the pediatrics department of Sousse during eight years period (1994-2001). Twenty three boys and eight girls aged two months to 13 years (mean age: 4 years and 8 months) were investigated. Among them, 24 patients suffered of tuberculosis (TBC) and 7 of disseminated BCG-osis. Pleuropulmonary TBC was observed in 12 patients either isolated (7 cases) or in association with at least another localization (5cases). 17 patients had extrapulmonary TBC with variable localisation. The 7 patients with disseminated BCG-osis had an underlying primary immunodeficiency of the cell-mediated immune response. CONCLUSION: The current epidemiology of mycobacterial infections in children in our region indicates a high frequency of severe adverse effects of BCG vaccination occurring in genetically immunodeficient children. 相似文献

Actinomycosis is an infection due to an anaerobic Gram-positive bacilus bacteria: Actinomyces. Tubo-ovarian locallisation is rare. It more often appears clinically as a pseudo-tumoral and feverish syndrom, evoking wrongly a malignant tumoral pathology, and often leads to a mutilating surgical treatment. Intra-uterine device appears as the principal favorable factor of this pathology. Basing on two cases reported by the authors, and after literature review, physiopathology, clinical and paraclinical expression, and treatment of this affection are discussed. A set up is made. 相似文献

Prune Belly syndrome is characterized by a combination of megacystis, anterior abdominal wall distension with deficiency of the abdominal wall musculature, and bilateral cryptorchidism. Diagnosis is easy after 15 weeks of gestation, but may be difficult at the end of the first term. Authors report 2 cases of Prune Belly syndrome diagnosed at 11 and 14 weeks of gestation respectively. After literature review, diagnosis and prognosis particularities of this syndrome are discussed. 相似文献

Two genetically unrelated OXA-163-carrying Klebsiella pneumoniae strains were identified from two infection cases in June 2009 and May 2010 in Cairo, Egypt. OXA-163-producing Enterobacteriaceae had been previously reported in Argentina only. Both patients had no history of travel abroad. The emergence of this newly recognized OXA-48-related β-lactamase able to hydrolyze cephalosporins and carbapenems is especially worrying in a geographic area where OXA-48 is endemic and effective surveillance for antibiotic resistance is largely unaffordable. 相似文献

BACKGROUND: Considered uncommon in western countries some years ago, hepatitis C virus of genotype 4 is now spreading in some areas of Europe. This is assumed to be due to immigration from a region of high prevalence for this genotype and to propagation among drug users. In the south of Belgium, genotype 4 currently accounts for 10% of hepatitis C virus patients and its prevalence is increasing with time. OBJECTIVE: To better define the genotype 4 carriers' characteristics. METHODS: In a database comprising 1726 viraemic hepatitis C virus patients, the files of 85 genotype 4 carriers were reviewed. RESULTS: Beside the African (58%) and European drug user (15%) subgroups classically described, a third subgroup consisting of European nondrug users (26%) was identified as peculiar: these patients were older, had been mostly contaminated sporadically, presented a great diversity of subtypes, and were mainly of Italian origin. In this subgroup, contamination was supposed to be ancient, having occurred probably in Italy before immigration into Belgium. By contrast, European drug users were infected with only two subtypes (4c/4d and 4), an observation in favour of recent spread. Africans had a great diversity of subtypes, were young, and were mostly contaminated sporadically in their home countries. Despite their epidemiological differences, the clinical management, and in particular the rates of eligibility for treatment, were similar for these three groups. CONCLUSIONS: Three different patterns of genotype 4 carriers were observed, corresponding to three different spreading profiles. They did not induce, however, different clinical management. 相似文献
