Results of TV imaging of Phobos (Experiment VSK-Fregat).

From February to March 1989 the Phobos 2 spacecraft took 37 TV images of Phobos at a distance of 190-1100 km. These images complement Mariner-9 and Viking data by providing higher-resolution coverage of a large region West of the crater Stickney (40-160 degrees W) and by providing disk-resolved measurements of surface brightness at a greater range of wavelengths and additional phase angles. These images have supported updated mapping and characterization of large craters and grooves, and have provided additional observations of craters' and grooves' bright rims.

[4 cases of botryoid sarcoma].

The authors describe the rare botryoid sarcoma--histomorphology, clinic, diagnosis, treatment and prognosis with a contribution of 4 own cases at the age up to 18 years. They indicate the difficulties in the establishment of the diagnosis-early clinical and histological-in three of the cases the histological examination did not establish immediately the exact diagnosis--the material was considered as "granulation tissue" or "fibroma mole". The results of the treatment are summarized as well as the choice of therapeutic methods and drugs.
