Ketoconazole suspension (20 mg per ml) was compared with nystatin (100,000 units per ml) in the treatment of oral candidosis in newborns and infants. In all patients Candida infection was proven by culture. Twenty patients were treated with ketoconazole and 15 patients with nystatin. Treatment was discontinued 2 days after clinical cure, or after 3 weeks. The investigator assessed the severity of the thrush and accompanying symptoms at the start of the study and at weekly controls. After one week all 20 patients on ketoconazole (100%) and 8 (53%) patients on nystatin were cured clinically. At the end of the treatment 12 patients on nystatin (80%) were cured. Clinical cure was confirmed by negative culture in 94% of the patients on ketoconazole and in 73% of the patients on nystatin. No side-effects were observed in the patients on ketoconazole. Only in the case of one patient on nystatin, was vomiting observed. This study shows that ketoconazole cures thrush faster and more effectively than nystatin. 相似文献

Objective
Hemophilic arthropathy, with characteristics of inflammatory (rheumatoid arthritis) and degenerative (osteoarthritis) joint damage, occurs at an early age, is associated with minor comorbidity, and is restricted to 3 pairs of large joints. The aim of this study was to determine whether commonly used serum and/or urinary biomarkers of cartilage and bone turnover for which assay kits are commercially available are associated with the severity of joint damage in patients with various degrees of hemophilic arthropathy and, thus, whether this disease could be useful in the identification and evaluation of such biomarkers.Methods
Blood and urine samples were collected from 36 patients with various degrees of hemophilic arthropathy. Commercially available assays for the most frequently investigated serum and urine biomarkers were performed: urinary C‐terminal telopeptide of type I collagen (CTX‐I), urinary CTX‐II, serum CTX‐I, serum CTX‐II, serum cartilage oligomeric matrix protein (COMP), serum cartilage cleavage products C1,2C and C2C, and serum chondroitin sulfate 846 (CS‐846). Radiographs of the ankles, knees, and elbows in all patients were evaluated for the degree of joint damage according to the Pettersson score, which is based on cartilage and periarticular bone changes and is specific for hemophilic arthropathy.Results
Urinary CTX‐II, serum C1,2C, and serum CS‐846 levels correlated with the overall Pettersson score and with the joint space narrowing component. Regression analysis showed that combined indexes of different markers increased the degree of correlation for the combination of urinary CTX‐II, serum COMP, and serum CS‐846. Bone‐specific markers (urinary/serum CTX‐I and serum C1,2C) did not correlate with specific bone‐related items of the Pettersson score (osteoporosis and erosions).Conclusion
These results support the idea that a combination of biomarkers relates significantly better to the severity of joint damage than do individual biomarkers. The combination of urinary CTX‐II, serum COMP, and serum CS‐846 correlated best with the degree of arthropathy. Because of its specific characteristics and restricted involvement, hemophilic arthropathy may prove useful in the screening of newly developed biomarkers of joint damage.66.

Objective
Human Hsp60 is expressed in the joints of patients with rheumatoid arthritis (RA) and can elicit a regulatory T cell response in the peripheral blood and synovial fluid. However, Hsp60 can also trigger strong proinflammatory pathways. Thus, to understand the nature of these Hsp60‐directed responses in RA, it is necessary to study such responses at the molecular, epitope‐specific level. This study was undertaken to characterize the disease specificity and function of pan–DR‐binding Hsp60–derived epitopes as possible modulators of autoimmune inflammation in RA.Methods
Lymphocyte proliferation assays (using 3H‐thymidine incorporation and carboxyfluorescein diacetate succinimidyl ester [CFSE] staining) and measurement of cytokine production (using multiplex immunoassay and intracellular staining) were performed after in vitro activation of peripheral blood mononuclear cells from patients with RA, compared with healthy controls.Results
A disease (RA)–specific immune recognition, characterized by T cell proliferation as well as increased production of tumor necrosis factor α (TNFα), interleukin‐1β (IL‐1β), and IL‐10, was found for 3 of the 8 selected peptides in patients with RA as compared with healthy controls (P < 0.05). Intracellular cytokine staining and CFSE labeling showed that CD4+ T cells were the subset primarily responsible for both the T cell proliferation and the cytokine production in RA. Interestingly, the human peptides had a remarkably different phenotype, with a 5–10‐fold higher IL‐10:TNFα ratio, compared with that of the microbial peptides.Conclusion
These results suggest a disease‐specific immune‐modulatory role of epitope‐specific T cells in the inflammatory processes of RA. Therefore, these pan–DR‐binding epitopes could be used as a tool to study the autoreactive T cell response in RA and might be suitable candidates for use in immunotherapy.67.

Essential oils are widely used in pharmaceutical, sanitary, cosmetic, agriculture and food industries for their bactericidal, virucidal, fungicidal, antiparasitical and insecticidal properties. Their anticancer activity is well documented. Over a hundred essential oils from more than twenty plant families have been tested on more than twenty types of cancers in last past ten years. This review is focused on the activity of essential oils and their components on various types of cancers. For some of them the mechanisms involved in their anticancer activities have been carried out. 相似文献

Objective. Inflammation-induced articular cartilage degradation is a major problem in rheumatoid arthritis (RA). Type 1 T cell activity (characterized by interferon-γ/interleukin-2 [IL-2] production), and consequently, the production of the proinflammatory cytokines IL-1 and tumor necrosis factor α (TNFα), have been reported to play a major role in cartilage damage. IL-10 and IL-4, both produced by type 2 T cells, are cytokines with the capacity to down-regulate proinflammatory responses. The present study was undertaken to investigate the way in which these cytokines affect activated mononuclear cells (MNC) of RA patients in relation to human articular cartilage degradation in vitro. Methods. MNC from synovial fluid and peripheral blood of RA patients were stimulated with bacterial antigen and treated with IL-10 and/or IL-4. Bacterial antigen is known to activate type 1 T cells and to induce proinflammatory IL-1/TNFα–dependent cartilage damage. Cytokine production and effects of conditioned media, as well as effects of IL-10 and IL-4 on proteoglycan (PG) turnover (as a measure for cartilage damage), were determined. Results. IL-10 and IL-4 inhibited proinflammatory cytokine production of stimulated RA MNC and completely reversed inhibition of cartilage PG synthesis induced by these stimulated RA MNC. IL-10 was more potent than IL-4 in this respect, and the combination of IL-10 and IL-4 had an additive effect. In addition, IL-10 directly stimulated cartilage PG synthesis. Conclusion. IL-10 reverses the cartilage degradation induced by antigen-stimulated MNC, and IL-4 has an additive effect on this process. Furthermore, IL-10 has a direct stimulatory effect on PG synthesis, and IL-4, as a growth factor for type 2 T cells, can reduce the ratio of type 1 to type 2 T cell activity. These results provide evidence in favor of the use of a combination of the two cytokines in the treatment of RA. 相似文献
