The aim of this study was to determine the expression intensity of PCNA and Ki-67 tissue antigens related to pathologically modified oral mucosa in OLR lesions, and to determine the reaction intensity of these antigens in individual clinical forms, i.e. lichen ruber planus (LRP) and lichen ruber erosivus (LRE) comparing the reaction intensity with the inflammation grade and the degree of hyperk...

Talaromyces emersonii, a thermophilic aerobic fungus, produces a complete xylan-degrading enzyme system when grown on appropriate substrates. In this paper we present the physicochemical and catalytic properties of three enzymes, xylosidase (Xyl) I (M(r) 181,000; pI 8.9), II (M(r) 131,000; pI 5.3) and III (M(r) 54,200; pI 4.2). Xyl I and II appear to be dimeric and Xyl III is a single-subunit p...

tiydroxylation of monacolin L to monacolin J by M. ruberlt8). The present communication deals with the transformation of monacolin J to monacolin K by a cell-free extract of M. ruber and by living cells of Paecilomyces viridis. The latter fungus is known to produce compactin (ML-236B) analogs, another family of HMG-CoAreductase inhibitors6). M. ruber M4681 was grown aerobically in a medium cont...

Our mouth is the mirror of our health and it might be said that numerous diseases which affect our organism may be manifested in the mouth. Early symptoms occurring within the oral cavity may emerge with diseases related to our blood system, gastrointestinal system, renal system, cardiovascular system, and mental system. They are manifested as a hyperkeratosis, which may have an erithematous ba...

Protaminobacter ruber was cultured in a medium containing [57Co]cyanocobalamin with a "two-step cultivation method" and the forms of vitamin B12 compounds in the cells were examined. Methylcobalamin was detected in the early phases of growth and reached a maximum of about 40% of all cobalamins extracted from the cells. In the stationary phase of growth, almost all cobalamins consisted of adenos...

The fungi isolated from 100 samples of flue-cured tobacco from 12 markets in 2 tobacco belts comprised 11 genera, including 10 species of Aspergillus. The mean percentage per sample isolated from 62 samples of tobacco from Middle Belt markets was Alternaria, 40.6%; Aspergillus niger, 47.8%; Aspergillus repens, 38.0%; and Penicillium, 25.8%. The mean percentage per sample isolated from 38 sample...
