Abstract
PURPOSE Microparticles (MPs) are membrane-derived vesicles measuring less than 1 μm in diameter. They are shed from nearly every activated or preapoptotic cell and may exhibit biologic activities in inflammation or apoptosis settings. The main purpose of this study was to determine whether MP shedding was higher in the vitreous of patients with retinal detachment (RD). METHODS This was a prospective, comparative study. Levels of vitreous MPs (including phosphatidylserine [PS]-expressing MPs, photoreceptor cell-derived MPs, and photoreceptor cell-derived MPs expressing PS) and soluble proinflammatory factors (i.e., monocyte chemoattractant protein-1, intercellular adhesion molecule-1, and IL-6) were analyzed by flow cytometry. Samples were obtained from 49 eyes undergoing RD surgery and 41 control eyes. RESULTS Vitreous levels of all the MPs studied were significantly increased in the RD group. Vitreous MP levels were correlated with levels of at least one proinflammatory factor depending on MP subsets. Concerning clinical parameters, vitreous PS-expressing MP and PS-expressing photoreceptor cell-derived MP levels were higher depending on the duration of RD at surgery, the detached retina surface, and the macula status and were found more sensitive than proinflammatory factors only for the duration of RD at surgery. CONCLUSIONS Vitreous concentrations of MPs (mainly derived from photoreceptor cells) are higher after rhegmatogenous RD and found to be correlated with soluble proinflammatory factors.

Abstract
The aim of this study was to explore lysozyme and lactoferrin concentrations in human immunodeficiency virus (HIV)-infected patients with oropharyngeal candidiasis (OPC). These proteins were measured by time-resolved immunofluorometric assay, validated in Part I of this study, in paired serum and salivary secretions of 30 patients. Eleven HIV-positive patients without OPC, eight HIV-positive patients with OPC and eleven HIV-negative healthy subjects were included in the study. The relative coefficient of excretion of salivary albumin was used to establish protein origin. In serum, the low lactoferrin concentrations in HIV-infected patients with and without OPC (0.610 mg/l (p < 0.05) and 0.896 mg/l (p < 0.01) vs. 1.439 mg/l in healthy subjects) were probably due to a decrease in nonspecific immunity, particularly the polymorphonuclear cells. In HIV-infected patients with OPC, the high salivary lysozyme and lactoferrin concentrations (170.94 mg/l and 66.48 mg/l vs. 23.35 mg/l and 10.20 mg/l in healthy subjects, respectively) and their mean relative coefficient of excretion of above 1 indicated a high local production of lysozyme and lactoferrin in saliva. The development of OPC in HIV-infected patients could be a consequence of inefficient lysozyme and lactoferrin concentrations and of decreased cooperation between innate and adaptative immune systems.

Abstract
Several studies were carried out to characterize the humoral immune response on mucosal genital surfaces. However, the results obtained so far were particularly conflicting due to the absence of validation methods. The aim of this study was to develop and validate a quantitative ELISA method, which is sensitive and reproducible, to measure immunoglobulin and secretory immunoglobulin concentrations in various biological fluids. This quantitative, sensitive (detection limit = 1 microg/L) and reproducible (coefficient of variation < 15%) method could be of interest to study the effects of viral infections on mucosal non-specific immune response in genital tract. To explore the humoral response, serum, saliva, vaginal secretions, and cervicovaginal secretions from 18 women, 20-45 years old, were evaluated for total-IgA, secretory IgA, IgM, and IgG. Albumin level was also evaluated by immuno-nephelometry. The secretion rates of immunoglobulins were measured by calculating their relative coefficients of excretion by reference to albumin. Despite large individual variations, median immunoglobulin levels were higher in the endocervical secretions than in the cervicovaginal secretions. When we compared the rates of immunoglobulins in genital fluids, IgG prevalence was higher (80%) in cervicovaginal and endocervical secretions than IgA prevalence (12%). In contrast, digestive mucosal secretions, such as saliva, contained mostly IgA (80%). In cervicovaginal and endocervical secretions, IgG and IgM originated mainly from serum, whereas a local synthesis provided total-IgA and secretory IgA. These results allowed us to raise a possible hypothesis for the origin of immunoglobulins in the genital tract. They illustrated the peculiar feature of the female reproductive tract and the difficulty for this tissue to contribute in the mucosal associated lymphoid tissue. The low secretory-IgA and total-IgA levels could explain the particular sensitivity of the vagina and the cervix to infections.

Abstract
Buccal and digestive tract opportunistic infections occur frequently in patients infected by HIV. In this study, we measured lysozyme (Lz), lactoferrin (Lf), total IgA (T-IgA), and secretory IgA (S-IgA) levels to investigate nonspecific secretory immunity in HIV-infected patients with oral candidiasis. Serum, saliva, and stool samples were analyzed by time-resolved immunofluorometric assay for Lz and Lf levels and by enzyme-linked immunosorbent assay for T-IgA and S-IgA levels. Mean salivary Lf and T-IgA levels (66.50 mg/L and 0.10 g/L, respectively) and mean fecal Lf, T-IgA, and S-IgA outputs (0.87, 54.0, and 43.6 mg/d, respectively) were significantly higher in HIV-infected patients with oropharyngeal candidiasis than in HIV-infected patients without oropharyngeal candidiasis and healthy subjects. There was a modification in the molecular form rate, with a high increase in S-IgA and monomeric IgA transudation from the plasmatic compartment into salivary and digestive fluids and an increase in salivary Lf local synthesis by polymorphonuclear neutrophils. HIV infection appears to be associated with dysregulation of some of the nonspecific immune factors at the mucosal surface. Despite high saliva concentrations and high intestinal output, innate immunity was not able to stop yeast expansion in HIV-infected patients.

Abstract
In addition to their antibacterial properties, quinolones are capable of modulating the immune response. The aim of this paper was to study the effects of a new fluoro-4-quinolone on the respiratory burst. We evaluated the effects of marbofloxacin on the activation of peripheral phagocytes in non-infected bovines after a 5-day treatment. The immunopharmalogical study measured the chemiluminescence response of phagocytic cells obtained from total blood. Serum cortisol and albumin levels were also measured. Data showed that the treatment with marbofloxacin induced a mild decrease in the oxidative response. There was no significant difference between serum albumin levels of normal values and those of before and after treatment, and the levels of serum cortisol were also not significantly different before and after treatment. These results suggest that marbofloxacin treatment could modulate the inflammatory response of phagocytic cells by counteracting the oxidative burst.
