Results of clinical and laboratory examination of animals experimentally infected with Taenia saginata eggs are described. At the early stage of infection, increased temperature, cough, muscle shaking and unstable pace were observed. The locomotive disorders disappeared only on day 50 p.i. Leukocytosis and peripheric eosinophilia were found at the early stage of infection. On days 14-28 p.i. the activity of serum creatine-kinase (CK) significantly increased. The activity of other enzymes (AST, ALT, LD, ALP and ALD) examined was increased only slightly and irregularly. The lipid content in blood serum markedly increased on days 9-16 p.i.

The aim of the present work was to explore possibilities of photocatalytic TiO2 coating for reducing biofilms on non-living surfaces. The model organism, Deinococcus geothermalis, known to initiate growth of durable, colored biofilms on machine surfaces in the paper industry, was allowed to form biofilms on stainless steel, glass and TiO2 film coated glass or titanium. Field emission electron microscopy revealed that the cells in the biofilm formed at 45 degrees C under vigorous shaking were connected to the surface by means of numerous adhesion threads of 0.1-0.3 microm in length. Adjacent cells were connected to one another by threads of 0.5-1 microm in length. An ultrastructural analysis gave no indication for the involvement of amorphous extracellular materials (e.g., slime) in the biofilm. When biofilms on photocatalytic TiO2 surfaces, submerged in water, were exposed to 20 W h m(-2) of 360 nm light, both kinds of adhesion threads were completely destroyed and the D. geothermalis cells were extensively removed (from >10(7) down to below 10(6) cells cm(-2)). TiO2 films prepared by the sol-gel technique were slightly more effective than those prepared by the ALD technique. Doping of the TiO2 with sulfur did not enhance its biofilm-destroying capacity. The results show that photocatalytic TiO2 surfaces have potential as a self-cleaning technology for warm water using industries.

X-linked adrenoleukodystrophy (X-ALD) is an inherited neurometabolic disease associated with the accumulation of very long-chain fatty acids. Mutations in the ABCD1 gene encoding ALD protein (ALDP) cause this clinically heterogeneous disorder, ranging from adrenocortical insufficiency and neurodegeneration to severe cerebral inflammation and demyelination. ALDP-deficient mice replicate metabolic dysfunctions and develop late-onset axonopathy but lack histological signs of cerebral inflammation and demyelination. To test the hypothesis that subtle destabilization of myelin may initiate inflammatory demyelination in Abcd1 deficiency, we generated mice with the combined metabolic defect of X-ALD and the mild myelin abnormalities of myelin-associated glycoprotein (MAG) deficiency. A behavioural phenotype, impaired motor performance and tremor, developed in middle-aged Mag null mice, independent of Abcd1 genotype. Routine histology revealed no signs of inflammation or demyelination in the CNS, but immunohistochemical analyses of spinal cord neuropathology revealed microglia activation and axonal degeneration in Mag and Abcd1/Mag double-knockout (ko) and, less severe and of later onset, in Abcd1 mutants. While combined Abcd1/Mag deficiency showed an additive effect on microglia activation, axonal degeneration, quantified by accumulation of amyloid precursor protein (APP) in axonal spheroids, was not accelerated. Interestingly, abnormal APP reactivity was enhanced within compact myelin of Abcd1/Mag double-ko mice compared to single mutants already at 13 months. These results suggest that ALDP deficiency enhances metabolic distress in oligodendrocytes that are compromised a priori by destabilised myelin. Furthermore, the age at which this occurs precedes by far the onset of axonal degeneration in Abcd1-deficient mice, implying that oligodendrocyte/myelin disturbances may precede axonopathy in X-ALD.

Adult-onset leukoencephalopathy involving the white matter of the brain is a heterogeneous disorder that exhibits a wide range of clinical manifestations. Recent advances in molecular genetics enable gene-based diagnosis of some forms of adult-onset leukoencephalopathy. In this review, the classification of adult-onset leukoencephalopathy based on molecular genetic findings is proposed. The autosomal dominant forms of adult-onset leukoencephalopathy include hereditary diffuse leukoencephalopathy with spheroids (HDLS), autosomal dominant adult-onset leukoencephalopathy (ALDL), cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), and Alexander disease. The autosomal recessive forms of adult-onset leukoencephalopathy include cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy (CARASIL), vanishing white matter (VWM) with leukoencephalopathy, Nasu-Hakola disease, and metachromatic leukodystrophy (MDL). X-chromosome-linked disorders include fragile X-associated tremor and ataxia syndrome (FXTAS) and adrenoleukodystrophy (ALD). Identification of the genes responsible for adult-onset leukoencephalopathy provides an important clue for elucidation of molecular pathophysiology underlying white matter disorders. One example is the identification of mutations in colony stimulating factor 1 receptor (CSF-1R) in patients with HDLS. Missense and splice site mutations have been found in the tyrosine kinase domain of CSF-1R. CSF-1R is highly expressed in microglia in the brain. It has been demonstrated that mice depleted of CSF-1R exhibit loss of microglia in the brain. In addition, stimulation of IL-34, a ligand of CSF-1R, induces proliferation and activation of microglia. These findings raise an intriguing possibility that dysfunction of microglia may play a role in the pathogenesis of white matter lesions occurring in patients with HDLS.
