[Diagnostic approach in mechanical jaundice, complicated by purulent cholangitis].

Up-to-date high-informative non-invasive diagnostic methods were used in 54 patients with obstructive jaundice (OJ) complicated by purulent cholangitis (PC). Treatment-diagnostic algorithm can to improve results of diagnosis. This algorithm is the following: ultrasonic examination as a screening method; if a case of jaundice is unclear and obturation is prolonged magnetic-resonance tomography and magnetic-resonance cholangiopancreaticography are carried out; in block of a distal part of the common bile duct--spiral computed tomography with bolus amplification and duodenoscopy.

[Characteristics of Triticum vulgare in the early phases of development (ontogenesis) in space flight].

The effect of space flight factors on the growth and development of wheat grown in a Svetoblock-M unit on the orbital station Mir was investigated. The data obtained allow the conclusion that wheat plants develop flight-induced changes. When compared to control plants, experimental plants show a delayed growth in terms of biometric parameters, different distribution of biogenic elements, lower phytoncidal activity, increased bacterial and fungal contamination, and a changed pigment and lipid composition.

[Formation of microbial biocenosis of wheat in a manned spacecraft].

Mutual effects of microbial complexes of biological objects, men and their environment are of crucial importance for manned space missions. The present experiment to study wheat microflora flown in a manned spacecraft was a continuation of investigations the purpose of which was to identify the pattern of formation of microbial cenosis of higher plants in a closed ecological system. It was found that the microbial cenosis of plants grown during an early period of vegetation in space was formed under the influence of the anthropogenic factor.
