Protein inhibitors are molecules secreted by many plants. In a functional genomics approach, an invertase inhibitor (SolyCIF) of Solanum lycopersicum was identified at the Solanaceae Cornell University data bank (www.sgn.cornell.edu). It was established that this inhibitor is expressed mainly in the leaves, flowers and green fruit of the plant and localized in the cell wall compartment. The SolyCIF cDNA was cloned by performing RT-PCR, fully sequenced and heterologously expressed in Pichia pastoris X-33. The purified recombinant protein obtained by performing ion-exchange chromatography and gel filtration was further biochemically characterized and used to perform affinity chromatography. The latter step made it possible to purify natural vacuolar invertase (TIV-1), which showed high rates of catalytic activity (438.3 U mg(-1)) and efficiently degraded saccharose (K(m)=6.4mM, V(max)=2.9 micromol saccharosemin(-1) and k(c)(at)=7.25 x 10(3)s(-1) at pH 4.9 and 37 degrees C). The invertase activity was strongly inhibited in a dose-dependent manner by SolyCIF produced in P. pastoris. In addition, Gel-SDS-PAGE analysis strongly suggests that TIV-1 was proteolyzed in planta and it was established that the fragments produced have to be tightly associated for its enzymatic activity to occur. We further investigated the location of the proteolytic sites by performing NH(2)-terminal Edman degradation on the fragments. The molecular model for TIV-1 shows that the fragmentation splits the catalytic site of the enzyme into two halves, which confirms that the enzymatic activity is possible only when the fragments are tightly associated.

Exosomes are vesicles secreted by most hematopoietic cells on fusion of multivesicular endosomes with the plasma membrane. Many studies have reported that exosomes may also be released by tumor cells. Exosomes are believed to play an antitumor role through immune cells. We asked whether tumor exosomes have biological activities on tumor cells. We report that human pancreatic tumor nanoparticles, exosome-like as characterized by proteomic analyses and rich in lipid rafts, decreased tumor cell proliferation. Nanoparticles increased Bax and decreased Bcl-2 expressions. Caspase-3 and -9 but not caspase-8 inhibitors impaired apoptosis, which implicates the mitochondria apoptotic pathway. The ceramide-sphingomyelin apoptotic pathway was inoperative. Moreover, nanoparticles induced phosphatase and tensin homolog (PTEN) and glycogen synthase kinase (GSK) -3beta activation and decreased pyruvate dehydrogenase activity. In nanoparticle-treated cells, PTEN formed complexes with actin, beta-catenin, and GSK-3beta. Thus, beta-catenin may no longer be available to activate the survival pathway. Nanoparticles triggered the down-regulation of cyclin D1 and poly(ADP-ribose) polymerase. Hence, nanoparticles counteracted the constitutively activated phosphatidylinositol 3-kinase/Akt survival pathway to drive tumor cells toward apoptosis. Our study provides the first evidence of an apoptotic function of tumor-derived nanoparticles on tumor cells. We propose a new role for nanoparticles, i.e., as signal carriers for interaction between cells, which may have implications in physiopathological situations.

Nucleotide oligomerisation domain 2 (NOD2) is a component of the innate immunity known to be involved in the homeostasis of Peyer patches (PPs) in mice. However, little is known about its role during gut infection in vivo. Yersinia pseudotuberculosis is an enteropathogen causing gastroenteritis, adenolymphitis and septicaemia which is able to invade its host through PPs. We investigated the role of Nod2 during Y. pseudotuberculosis infection. Death was delayed in Nod2 deleted and Crohn's disease associated Nod2 mutated mice orogastrically inoculated with Y. pseudotuberculosis. In PPs, the local immune response was characterized by a higher KC level and a more intense infiltration by neutrophils and macrophages. The apoptotic and bacterial cell counts were decreased. Finally, Nod2 deleted mice had a lower systemic bacterial dissemination and less damage of the haematopoeitic organs. This resistance phenotype was lost in case of intraperitoneal infection. We concluded that Nod2 contributes to the susceptibility to Y. pseudotuberculosis in mice.

Whipple's disease (WD) is a chronic multisystemic infection, caused by the bacterium Tropheryma whipplei. The main clinical presentations are classic WD (CWD) with histologic lesions in the gastrointestinal tract, endocarditis, and isolated neurologic infection. The current strategy for diagnosis remains invasive.The present study aimed to select the protein candidates for serological diagnosis of WD. The first step was to identify candidate proteins by an immunoproteomic approach combining 2-DE using a total extract of a T. whipplei, immunoblotting, and MS. The second step was to validate the discovered biomarkers using a recombinant protein-based ELISA. Serum samples from 18 patients with WD and from 54 control individuals were tested. A sugar ABC transporter, TWT328 (sensitivity (Se) 61%, specificity (Sp) 87%, positive predictive value (PPV) 61%, negative predictive value (NPV) 87%, and positive likelihood ratio (PLR) 4.69) was the best marker for development of serodiagnosis for CWD. We also obtained a reproducible immunoreactive protein pattern for patients with isolated neurological infection due to T. whipplei (Se 100%, Sp 93%, PPV 55.5%, NPV 100%, and PLR 13.51) as an encouraging step towards noninvasive diagnosis of this particular manifestation. Nine recombinant candidates have been successfully screened with serum samples. Results from these ELISA assays skewed with those obtained with immunoblots., (Copyright © 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.)

Vinca alkaloids vinblastine and vincristine and some of their derivatives such as vinorelbine are widely used in therapy of leukemia and several solid tumors. Their action is associated with alterations of the mitotic spindle functions that prevent the cell cycle progression and lead to mitotic block. A number of studies show that some Vinca alkaloids inhibit CaM-target interaction. The newest microtubule inhibitor, vinflunine (Javlor), currently in clinical trials, is remarkably more active than vinblastine against a number of tumors. Moreover, vinflunine is significantly less toxic than other Vinca alkaloids. The high antitumor activity of this molecule is not well understood since it binds to tubulin with an overall affinity several-fold lower than that of vinblastine or vincristine. In this study, we examined the interaction of Ca2+-CaM with vinflunine, vinblastine, and stable tubule only polypeptide (STOP) by using a combination of thermodynamic and mass spectrometric approaches. We characterized the influence of Vinca alkaloids on Ca2+-CaM-STOP complex formation. Our results revealed different binding modes to Ca2+-CaM for vinflunine and vinblastine, highlighting that adding fluorine atoms on the cleavamine moiety of the Vinca alkaloid molecule is critical for the localization of the drug on calmodulin. We demonstrate that vinflunine is a better inhibitor for STOP binding to calmodulin than vinblastine. We suggest that vinflunine action on calmodulin can have an effect on microtubule dynamics. These data may contribute to a better understanding of the superior antitumor efficiency and lower toxicity of vinflunine.

Exposure to vectors of infectious diseases has been associated with antibody responses against salivary antigens of arthropods among people living in endemic areas. This immune response has been proposed as a surrogate marker of exposure to vectors appropriate for evaluating the protective efficacy of antivectorial devices. The existence and potential use of such antibody responses in travellers transiently exposed to Plasmodium or arbovirus vectors in tropical areas has never been investigated. The IgM and IgG antibody responses of 88 French soldiers against the saliva of Anopheles gambiae and Aedes aegypti were evaluated before and after a 5-month journey in tropical Africa. Antibody responses against Anopheles and Aedes saliva increased significantly in 41% and 15% of the individuals, respectively, and appeared to be specific to the mosquito genus. A proteomic and immunoproteomic analysis of anopheles and Aedes saliva allowed for the identification of some antigens that were recognized by most of the exposed individuals. These results suggest that antibody responses to the saliva of mosquitoes could be considered as specific surrogate markers of exposure of travellers to mosquito vectors that transmit arthropod borne infections.

Radiofrequency ablation is increasingly used in the treatment of hepatic tumors. Planning the percutaneous intervention is essential and particularly difficult. In this paper, we focus on an automated computation of optimal needle insertion in computer-assisted surgery with 3D visualization. First, we review our method which delineates on the skin of a virtual patient the candidate zones for needle insertion, i.e., those which allow safe access to the tumor. In each case, we look for the trajectory that minimizes the volume of burnt tissue. Secondly, we introduce a quasi-exhaustive method that allies sampling and certified minimization to form a strong argument for the accuracy of our results. We also compare results of applying both methods on 7 representative reconstructed patient cases.

An increased risk for multiple sclerosis and schizophrenia is observed at increasing latitude and in patients born in winter or spring. To explore a possible link between maternal vitamin D deficiency and these brain disorders, we examined the impact of prenatal hypovitaminosis D on protein expression in the adult rat brain. Vitamin D-deficient female rats were mated with vitamin D normal males. Pregnant females were kept vitamin D-deficient until birth whereupon they were returned to a control diet. At week 10, protein expression in the progeny's prefrontal cortex and hippocampus was compared with control animals using silver staining 2-D gels associated with MS and newly devised data mining software. Developmental vitamin D (DVD) deficiency caused a dysregulation of 36 brain proteins involved in several biological pathways including oxidative phosphorylation, redox balance, cytoskeleton maintenance, calcium homeostasis, chaperoning, PTMs, synaptic plasticity and neurotransmission. A computational analysis of these data revealed that (i) nearly half of the molecules dysregulated in our animal model have also been shown to be misexpressed in either schizophrenia and/or multiple sclerosis and (ii) an impaired synaptic network may be a consequence of mitochondrial dysfunction.

Percutaneous radiofrequency ablation is a minimally invasive therapy for the treatment of liver tumors that consists in a destruction of tumors by heat. A correct insertion and placement of the needle inside the tumor is critical and conditions the success of the operation. We are developing a software that uses patients data to help the physician plan the operation. In this context, we propose a method that computes automatically, quickly and accurately the areas on the skin that provide a safe access to the tumor. The borders of the 3D mesh representing insertion areas are refined for a higher precision. Resulting zones are then used to restrict the research domain of the optimization process, and are visualized on the reconstructed patient as an indication for the physician.

In this paper, we propose a method based on multiple criteria to assist physicians in planning percutaneous RFA on liver. We explain how we extracted information from literature and interviews with radiologists, and formalized them into geometric constraints. We expose then our method to compute the most suitable needle insertion in two steps: computation of authorized insertion zones and multi-criteria optimization of the trajectory within this zones. We focus on the combination of the criteria to optimize and on the optimization step.

C reactive protein, the most sensible acute phase protein of inflammation and the labororatory should perform CRP testing on a continous 24 hour basis. The measurement is mainly performed by immunoturbimetry and immunonephelemetry methods available on multiparametric biochemical analyzer. In this study, we evaluated the analytical performances, precision and exactitude, of the CRP Diasys reagent on Roche Hitachi 917. The results were compared to those obtained with a CRP latex immunoassay (Roche). The reagent showed high analytical characteristics and especially a significant precision in a large range of CRP levels including low levels between 1 and 3 mg/L. Although this reagent is not considered as a high-sensitive CRP reagent, the measurement quality obtained in the 1-3 mg/L range allows an utilization as a cardiovascular risk predictor.

To assess intestinal lipid rafts functions through the characterization of their protein markers, we have isolated lipid rafts of rat mucosa either from the total membrane or purified brush-border membrane (BBM) by sucrose gradient fractionation after detergent treatment. In both membrane preparations, the floating fractions (4-5) were enriched in cholesterol, ganglioside GM1, and N aminopeptidase (NAP) known as intestinal lipid rafts markers. Based on MALDI-TOF/MS identification and simultaneous detection by immunoblotting, 12 proteins from BBM cleared from contaminants were selected as rafts markers. These proteins include several signaling/trafficking proteins belonging to the G protein family and the annexins as well as GPI-anchored proteins. Remarkably GP2, previously described as the pancreatic granule GPI-anchored protein, was found in intestinal lipid rafts. The proteomic strategy assayed on the intestine leads to the characterization of known (NAP, alkaline phosphatase, dipeptidyl aminopeptidase, annexin II, and galectin-4) and new (GP2, annexin IV, XIIIb, Galpha(q), Galpha(11), glutamate receptor, and GPCR 7) lipid rafts markers. Together our results indicate that some digestive enzymes, trafficking and signaling proteins may be functionally distributed in the intestine lipid rafts.

This report improves analytical procedures to investigate the behaviour of the two Vitamin E forms, alpha-tocopherol (Tol) and alpha-tocopheryl acetate (Tac), in model systems mimicking the intestinal medium. We describe how to prepare mixed micelles as vehicle for Tac and Tol and the HPLC method for their quantification in the micelles. Tac and Tol were extracted using ethanol-hexane-drying procedure, whereas the separation and detection were performed in methanol and by UV method, respectively. Both compounds were eluted in less than 4 min. In the range between 1.7 microM and 54 microM of Tac or Tol in the micelles, their recovery were 89% and 81%, respectively, with correlation coefficient over 0.99 and R.S.D. of less than 7.2% in all cases. Limits of detection and quantification for Tac and Tol in mixed micelles ranged between 1 microM and 2 microM and between 3 microM and 5 microM, respectively. The behaviours of Tac and Tol were quite different during the extraction procedure and both were influenced by the vitamin concentration and the relative volume of organic solvents.

For radiofrequency ablation (RFA) of liver tumors, evaluation of vascular architecture, post-RFA necrosis prediction, and the choice of a suitable needle placement strategy using conventional radiological techniques remain difficult. In an attempt to enhance the safety of RFA, a 3D simulator, treatment planning, and training tool, that simulates the insertion of the needle, the necrosis of the treated area, and proposes an optimal needle placement, has been developed. The 3D scenes are automatically reconstructed from enhanced spiral CT scans. The simulator takes into account the cooling effect of local vessels greater than 3 mm in diameter, making necrosis shapes more realistic. Optimal needle positioning can be automatically generated by the software to produce complete destruction of the tumor, with maximum respect of the healthy liver and of all major structures to avoid. We also studied how the use of virtual reality and haptic devices are valuable to make simulation and training realistic and effective.

The Enterobacter aerogenes eefABC locus, which encodes a tripartite efflux pump, was cloned by complementation of an Escherichia coli tolC mutant. E. aerogenes deltaacrA expressing EefABC became less susceptible to a wide range of antibiotics. Data from eef::lacZ fusions showed that eefABC was not transcribed in the various laboratory conditions tested. However, increased transcription from Peef was observed in an E. coli hns mutant. In addition, EefA was detected in E. aerogenes expressing a dominant negative E. coli hns allele.

High concentrations of certain amino acids are known to affect hormonal secretion, immune function, electrolyte balance or metabolic functions. However, there is a lack of knowledge regarding the molecular mechanisms responsible for these effects. We showed that, as well as spermidine transport, the activity of ornithine decarboxylase (ODC), the first and rate-limiting enzyme in polyamine biosynthesis, is decreased in human colon adenocarcinoma cells, Caco-2, following a 4-h supplementation with one of the two polyamine precursor amino acids, L-arginine or L-methionine. Dose-response assays indicated that the inhibitory effect of supplemental L-methionine was stronger than that of supplemental L-arginine. However, it was transient, being even replaced by ODC induction after 8 h, whereas the inhibitory effect of L-arginine lasted for at least 8 h. Unlike L-cysteine, neither L-methionine nor L-arginine could inhibit ODC activity in a crude acellular preparation of the enzyme. The inhibition of ODC activity in cells exposed to L-methionine or L-arginine was due to a decreased abundance of ODC protein without change at the mRNA level and each of these amino acids could counteract ODC induction by a glycine supplement. Contrary to the latter, supplemental L-methionine or L-arginine induced a marked decrease in ODC half-life, concomitantly with an increase in the activity of antizyme, an ODC inhibitory protein. Thus, depending on their nature, amino acids can up- or downregulate ODC activity at the protein stability level.

Percutaneous radiofrequency ablation has become a frequently used technique for the treatment of liver cancers, but still remains very difficult to plan. In this paper, we propose a robust method to delineate on the skin of a 3D reconstructed patient the zones that are candidate for an insertion, because they allow a safe access to the tumor without meeting any organ, and to compute automatically within these zones an optimal trajectory minimizing the volume of necrosis covering the tumor.

The filamentous fungus Penicillium funiculosum produces a mixture of modular and non-modular xylanases belonging to different glycoside hydrolase (GH) families. In the present study, we heterologously expressed the cDNA encoding GH11 xylanase B (XYNB) and studied the enzymatic properties of the recombinant enzyme. Expression in Escherichia coli led to the partial purification of a glutathione fusion protein from the soluble fraction whereas the recombinant protein produced in Pichia pastoris was successfully purified using a one-step chromatography. Despite O-glycosylation heterogeneity, the purified enzyme efficiently degraded low viscosity xylan [K(m)=40+/-3 g l(-1), V(max)=16.1+/-0.8 micromol xylose min(-1) and k(cat)=5405+/-150 s(-1) at pH 4.2 and 45 degrees C] and medium viscosity xylan [K(m)=34.5+/-3.2 g l(-1), V(max)=14.9+/-1.0 micromol xylose min(-1)k(cat)=4966+/-333 s(-1) at pH 4.2 and 45 degrees C]. XYNB was further tested for its ability to interact with wheat xylanase inhibitors. The xylanase activity of XYNB produced in P. pastoris was strongly inhibited by both XIP-I and TAXI-I in a competitive manner, with a K(i) of 89.7+/-8.5 and 2.9+/-0.3 nM, respectively, whereas no inhibition was detected with TAXI-II. Physical interaction of both TAXI-I and XIP-I with XYNB was observed using titration curves across a pH range 3-9.

Rat kidney acylase I was characterised by performing site-directed mutagenesis and enzymatic analysis in the presence of various chemical inhibitors. Site-directed mutagenesis on E147 and overexpression of the protein in a bacterial system, revealed the importance of this residue in enzymatic activity, it corresponds to the putative catalytic E175 in carboxypeptidase G2 from Pseudomonas aeruginosa. The reactivity of histidine and cysteine residues of acylase I with diethylpyrocarbonate (DEPC) and mercuric chloride, respectively, showed that these two amino acids are required for the enzyme to be fully active. Interestingly, the effects of mercuric chloride on rat kidney acylase I were not as great as those on the porcine enzyme, in agreement with previously observed differences between the two enzymes. Moreover, N-[3-(2-furyl)-acryloyl-L-methionine] (FA-Met) a synthetic substrate of the porcine acylase I was found to be an inhibitor of the rat kidney enzyme. These results strongly suggest the existence of differences between the active site of rat and porcine kidney acylases I. Lastly, the rat kidney enzyme was as sensitive as its porcine counterpart to two metal chelating agents, 1,10-phenanthroline and ethylenediamine tetraacetate (EDTA).

The effect of the slow rotating clinostat (1 rpm) on the growth of the primary root was studied on Brassica napus seedlings. After 5 d in darkness, the primary root was longer and thinner in seedlings grown on the clinostat than in seedlings grown in the vertical position. However, the breakdown of lipid reserves, sucrose level and transport of 14C-labeled sucrose from the cotyledons to the primary root, were not altered by growth on the clinostat. Moreover, the activity of isocitrate lyase, one of the two enzymes necessary for the conversion of lipids into glucids also was also not modified in the cotyledons of clinorotated seedlings. Thus, there was clear evidence that clinorotation had a direct effect on the growth of the primary root that was independent of the mobilisation of lipid reserves in the cotyledons. As a sink, the primary root had the same strength on the clinostat as in the vertical position, but the reserves were used in a different way. The increase in root elongation on the clinostat could be due to the slight, but continuous, omnilateral gravitropic stimulation due to the rotation of the seedlings about a horizontal axis.

The acylpeptide hydrolase of porcine intestinal mucosa (pi-APH) is a serine peptidase belonging to the prolyl oligopeptidase family. The enzyme catalyzes the release of N-terminal acylamino acids, especially acetylamino acids, from acetylpeptides. pi-APH is an homotetramer of approximately 300 kDa. We report the loss of the native tetrameric structure of pi-APH upon citraconylation and the process was reversed at acidic pH, indicating that the subunits were noncovalently bound. Determination of free cysteines in combination with peptide mapping suggested the involvement of all cysteines in disulfide bridges. Two structural domains were identified based on the three-dimensional model of pi-APH monomer: a beta-propeller fold in the N-terminal sequence (113-455) and an alpha/beta hydrolase fold corresponding to the C-terminal catalytic domain (469-732). Preferential cleavage sites for limited proteolysis with trypsin occurred within the beta-propeller domain, in agreement with the three-dimensional model. The putative role of this domain in the specificity mechanism of APH enzymes is also discussed.

A new cellulosomal protein from Clostridium cellulolyticum Cel9M was characterized. The protein contains a catalytic domain belonging to family 9 and a dockerin domain. Cel9M is active on carboxymethyl cellulose, and the hydrolysis of this substrate is accompanied by a decrease in viscosity. Cel9M has a slight, albeit significant, activity on both Avicel and bacterial microcrystalline cellulose, and the main soluble sugar released is cellotetraose. Saccharification of bacterial microcrystalline cellulose by Cel9M in association with two other family 9 enzymes from C. cellulolyticum, namely, Cel9E and Cel9G, was measured, and it was found that Cel9M acts synergistically with Cel9E. Complexation of Cel9M with the mini-CipC1 containing the cellulose binding domain, the X2 domain, and the first cohesin domain of the scaffoldin CipC of the bacterium did not significantly increase the hydrolysis of Avicel and bacterial microcrystalline cellulose.

CNBr fragments from porcine intestinal glycerol-ester hydrolase were separated by SDS/PAGE under reducing and nonreducing conditions, and their amino-acid sequences were analysed. Two intra-chain disulfide bridges were identified, namely Cys70-Cys99 (loop A) and Cys256-Cys267 (loop B). As the Cys71 sulfhydryl group could not be alkylated with iodoacetamide, it is suggested that the residue is blocked rather than being present in the free form. The two disulfide bridges of intestinal glycerol-ester hydrolase are present in the cholinesterase family, although the enzyme showed only about 35% identity with these proteins. Furthermore, the finding that glycerol-ester hydrolase was partly inactivated under reducing conditions suggests that one or both disulfide bridges are important for the enzyme conformation. Lastly, glycerol-ester hydrolase was also found to hydrolyse cholinergic substrates, although residues Trp86 and Asp74 which are considered to be the main constituents of the 'anionic' subsite responsible for substrate binding in cholinesterases were absent from loop A. Other amino-acid residues in the glycerol-ester hydrolase may therefore be responsible for the binding of cholinergic substrates to the enzyme.

A glycerol-ester hydrolase was purified to homogeneity from porcine intestinal mucosa using a partial delipidation method and an eight-step purification procedure. The isolation scheme used gave a 483-fold purification, resulting in a pure enzyme with a specific activity on tributyrin of 290 micromol x min(-1) x mg(-1). The molecular mass of the enzyme was estimated at 240 kDa, based on the results of size-exclusion chromatography, and at 60 kDa, as determined by SDS/PAGE analysis. The isoelectric focusing data obtained indicated that only one isoform with a pI of 5.1 was present. Complete identity was found to exist between the N-terminal sequence of the first 25 amino acid residues and that of a porcine liver carboxylesterase. A full-length cDNA coding for the enzyme was isolated from pig small intestine. We observed that the corresponding protein originally named intestinal glycerol-ester hydrolase definitely belongs to the carboxylesterase family. The deduced amino acid sequence consisted of 565 residues and showed 97% identity with that of porcine liver carboxylesterase and more than 50% identity with those of other carboxylesterases from different mammalian species.

This randomized, single-masked, multicenter clinical trial, comprising 95 patients enrolled at five sites, evaluated the performance of AMO Vitrax and Healon viscoelastic materials during cataract surgery. Patients were examined preoperatively and at one day, four days, one month, and three months postoperatively. The following measurements were recorded and analyzed: percentage of endothelial cell loss from preoperative to three months postoperative; change in intraocular pressure (IOP) from preoperative to 24 hours postoperatively; postoperative corrected visual acuity; subjective assessment of ability of viscoelastic to create and maintain tissue space; intraocular transparency; ease of evacuation. Three months postoperatively, endothelial cell loss was 4.9% (+/- 8.3%) for the AMO Vitrax group and 6.3% (+/- 10.5%) for the Healon group. One day postoperatively, IOP decreased by 1.6 mm Hg and increased by +1.1 mm Hg, respectively. Postoperative visual acuities were similar between the two groups at three months. Subjective assessment of transparency was higher for Healon. Assessment of tissue space maintenance was similar between the two materials. Healon was rated as slightly easier to evacuate.

A case of deep traumatic keratomycosis due to Aspergillus fumigatus with anterior chamber involvement is reported. Corneal perforation was threatening because of the large deep and long standing ulcer. This case emphasizes the difficulties of etiological diagnosis and treatment of keratomycosis. The authors analyse the peculiarities of corneal mycotic abcess and emphasize the importance of corneal cultures; they discuss the most recent therapeutic protocols for these lesions. After a very poor response to conventional antifungal therapy, total and quick recovery was acquired using itraconazole per os and topical Amphotericine B. The efficiency of itraconazole proves its antifungal activity against Aspergillus fumigatus and its good penetration to the deeper layers of the cornea and of the anterior chamber.
