[Degradation of lignin-carbohydrate substrate by soil fungi--producers of laccase and cellobiose dehydrogenase].

The growth of nonsporulating mycelial fungi INBI 2-26(+), producer of laccase; INBI 2-26(-), producer of cellobiose dehydrogenase; and their mixed culture on lignin-carbohydrate substrates under conditions of submerged fermentation were studied. The degrees of degradation of lignin, cellulose, and hemicellulose of cut straw over 23 days amounted to 29.8, 51.

[Isolation and characterization of a cellobiose dehydrogenase formed by a asporogenic mycelial fungus INBI 2-26(-)].

A nonsporulating fungus isolated from dioxine-containing tropical soils forms cellobiose dehydrogenase, when grown in media supplemented by a source of cellulose. The enzyme purified to homogeneity by SDS-PAGE (yield, 43%) had an M(r) of 95 kDa; its pH optimum was in the range 5.5-7.

[Prediction of infectious complications of eye penetrating wounds by R protein concentration in lacrimal fluid].

Analysis of the lacrimal fluid of normal subjects and patients after cataract extraction and with penetrating wounds of the eyeball showed fluctuations of the R protein concentration, which depended on the type of the injury and its complications. The authors propose using measurements of R protein in the lacrimal fluid as a prognostic criterion predicting the development of infectious complications in penetrating wounds of the eyeball.

[Role of hyperbaric oxygenation in mechanisms correcting the immunological reactivity in endotoxic shock and serum sickness].

The adaptation effect of hyperbaric oxygenation (3.0 Ata for 60 min) on white rats and mice with acute serum sickness is due to stimulation of non-pathogenic circulating immune complexes which do not fix the complement nor induce immune injuries to the kidneys. This promotes recovery of nephron ultrafiltration and decreases proteinuria.

[Cytologic study of the gingival fluid in inflammatory diseases of the periodontium].

The findings of a cytologic study of the gingival fluid in patients with gingivitis and periodontitis have revealed differences in the cellular composition of the gingival fluid in normal subjects and patients with gingivitis and periodontitis. This recommends such studies for the diagnosis of inflammatory diseases of the periodontium and for the differential diagnosis between gingivitis and periodontitis.
