A double-blind controlled trial in 24 lepromatous leprosy patients in reaction showed that clofazimine (Lamprene) controlled symptoms of erythema nodosum leprosum reaction in lepromatous leprosy better than prednisolone. Clofazimine also appeared to be significantly superior in preventing recurrence once the reaction had been controlled. There was a statistically significant rise in serum albumin among inpatients on clofazimine as compared with patients on prednisolone, but no difference in terms of neurological status, bacterial index, morphological index, and renal functions. Red/black hyperpigmentation was seen among practically all patients on clofazimine. No other side-effects or deleterious systemic effects were observed. 相似文献

A reversed-phase high-performance liquid chromatographic method is reported for the analysis of sulphur mustard in blood with the aid of solid-phase extraction sample preparation. Sulphur mustard is extracted from blood samples (both in vitro and in vivo) of rats with a solution of 0.05 M sodium dodecyl sulphate and pre-concentrated over Sep-Pak C18cartridges pre-coated with Tween-20. A Polygosil C18 column is used with acetonitrile—water (52:48, v/v) as mobile phase for separation and sulphur mustard was detected at 200 nm. 相似文献

Carbon prepared from silk cotton hull was used to remove a textile dye (reactive blue MR) from aqueous solution by an adsorption technique under varying conditions of agitation time, dye concentration, adsorbent dose and pH. Adsorption depended on solution pH, dye concentration, carbon concentration and contact time. Equilibrium was attained with in 60 min. Adsorption followed both Langmuir and Freundlich isotherm models. The adsorption capacity was found to be 12.9 mg/g at an initial pH of 2+/-0.2 for the particle size of 125-250 microm at room temperature (30+/-2 degrees C). 相似文献

This study involved the development of formaldehyde-treated, deseeded sunflower head waste–based biosorbent (FSH) for the biosorption of Cr(VI) from aqueous solution and industrial wastewater. Batch-mode experiments were conducted to determine the kinetics, sorption isotherms, effect of pH, initial Cr(VI) concentration, biosorbent dose, and contact time. The results demonstrated that FSH can sequester Cr(VI) from the aqueous solution. The maximum sorption occurred at pH = 2.0, biosorbent dose = 4.0 g/L, concentration of 100 mg/L at 25°C at 180 rpm after 2 h contact time. The FSH had an adsorption capacity of 7.85 mg/g for Cr(VI) removal at pH 2.0. The rate of adsorption was rapid, and equilibrium was attained within 2 h. The equilibrium sorption data fitted the Langmuir isotherm model, which was further confirmed by the chi-square test. 相似文献

Female patients affected by Fabry disease, an X-linked lysosomal storage disorder, exhibit a wide spectrum of symptoms, which renders diagnosis, and treatment decisions challenging. No diagnostic test, other than sequencing of the alpha-galactosidase A gene, is available and no biomarker has been proven useful to screen for the disease, predict disease course and monitor response to enzyme replacement therapy. Here, we used urine proteomic analysis based on capillary electrophoresis coupled to mass spectrometry and identified a biomarker profile in adult female Fabry patients. Urine samples were taken from 35 treatment-naïve female Fabry patients and were compared to 89 age-matched healthy controls. We found a diagnostic biomarker pattern that exhibited 88.2% sensitivity and 97.8% specificity when tested in an independent validation cohort consisting of 17 treatment-naïve Fabry patients and 45 controls. The model remained highly specific when applied to additional control patients with a variety of other renal, metabolic and cardiovascular diseases. Several of the 64 identified diagnostic biomarkers showed correlations with measures of disease severity. Notably, most biomarkers responded to enzyme replacement therapy, and 8 of 11 treated patients scored negative for Fabry disease in the diagnostic model. In conclusion, we defined a urinary biomarker model that seems to be of diagnostic use for Fabry disease in female patients and may be used to monitor response to enzyme replacement therapy. 相似文献

The aim of this study was to evaluate probiotic properties of antimicrobial Lactobacillus plantarum VJC38 in vitro. L. plantarum VJC38 was isolated from the crop of broiler chicken and characterized using dnaK gene sequence. The inhibitory activities of L. plantarum VJC38 against bacterial and fungal pathogens were evaluated. Antifungal compounds secreted by the strain VJC38 were identified using Gas Chromatography and Mass Spectrometry (GC-MS). The strain was evaluated for its tolerance to low pH, resistance to bile salts, auto-aggregation, co-aggregation with pathogenic Escherichia coli, cell surface hydrophobicity, cholesterol lowering activity, β-galactosidase production, adhesion ability to Caco-2 cells, mucin degradation, hemolytic activity and biogenic amine production. Phylogenetic analysis of dnaK gene of bacterial strain VJC38 showed 99% sequence similarity to Lactobacillus plantarum var. plantarum. It showed effective inhibition against food spoiling and pathogenic organisms like Escherichia coli, Listeria monocytogenes, Staphylococcus aureus, Aspergillus niger, Penicillium expansum and Eurotium species. The antifungal compound phenol- 2,4-bis(1,1-dimethylethyl) (PD) was identified in the culture filtrate of L. plantarum VJC38 and reported to have inhibition against Aspergillus species. L. plantarum VJC38 exhibited tolerance to low pH, resistance to bile salts, bile salt hydrolase activity, auto-aggregation (87.5%), co-aggregation with Escherichia coli (55.7%), cholesterol lowering activity (64%), β-galactosidase production (1206 MU), adherence to Caco-2 cells (11%), negative for mucin degradation, hemolytic activity and biogenic amine production. L. plantarum VJC38 could be a good candidate for further investigation in vivo to elucidate its health benefits and to evaluate its technological properties as a bio-protective strain. 相似文献

Removal of heavy metals from industrial wastewaters by adsorption onto activated carbon prepared from an agricultural solid waste 总被引:9,自引:0,他引:9
Activated carbon was prepared from coirpith by a chemical activation method and characterized. The adsorption of toxic heavy metals, Hg(II), Pb(II), Cd(II), Ni(II), and Cu(II) was studied using synthetic solutions and was reported elsewhere. In the present work the adsorption of toxic heavy metals from industrial wastewaters onto coirpith carbon was studied. The percent adsorption increased with increase in pH from 2 to 6 and remained constant up to 10. As coirpith is discarded as waste from coir processing industries, the resulting carbon is expected to be an economical product for the removal of toxic heavy metals from industrial wastewaters. 相似文献

A comparison of clofazimine and dapsone in the management of untreated lepromatous leprosy showed no significant differences between the two drugs in terms of morphological and bacterial indices. The incidence of erythema nodosum leprosum was similar in the two groups. Since dapsone is cheaper than clofazimine it remains the drug of choice for the routine management of untreated lepromatous leprosy. 相似文献

The molluscicidal effect of nicotinanilide was evaluated and compared with niclosamide (2',5-dichloro-4'-nitrosalicylanilide, ethanolamide salt) against different stages of the freshwater snail Lymnaea luteola i.e., eggs, immature, young mature, and adults. Calculated values of lethal concentrations (LC50 and LC90) showed that both nicotinanilide and niclosamide as toxic against eggs, immature, and adults. The young mature stage of the snails was comparatively more tolerant to both molluscicides than the other stages. The toxicity of the intermediate compounds of nicotinanilide against the young mature stage of the snails showed them as ineffective. The mortality pattern of the snails exposed to LC90 concentration of these molluscicides showed niclosamide to kill faster (within 8 to 9 h) than nicotinanilide (26 to 28 h). In view of the above studies it may be concluded that both molluscicides are toxic against all the stages of the L. luteola snails. 相似文献
