Abstract: A telescopic guide, especially for transmittance of torque in alternating directions and of the type which comprises a telescopic shaft (1) having at least three axial guide grooves (4-6) distributed round the telescopic shaft, an outer telescopic sleeve (2) having inner axial counter grooves (12) provided round the sleeve substantially like the guide grooves (4-6) of the telescopic shaft (1), and several transmittance elements provided between the guide grooves (4-6) of the telescopic shaft and the counter grooves (12) of the telescopic sleeve (2). The transmittance elements preferably are rows of balls, in which at least one such row has balls of a relatively «elastic» material, whereas the other rows comprise balls of a material which is «hard» in relation to said «elastic» material. The balls of «elastic» material may have a slightly larger dimension than the grooves (4) of the telescopic shaft and the counter grooves (12) of the telescopic sleeve (2) whereas the balls of «harder» material may have a slightly less dimension than the equivalent grooves (5, 6) and counter grooves respectively. Preferably the grooves 5, 6 of the telescopic shaft (1) for the «hard balls» are angularly displaced in relation to the equivalent counter grooves of the telescopic sleeve (2) such that the points of contact for two adjacent «hard» balls with the telescopic shaft (1) and the telescopic sleeve (2) are located on common mutually parallel planes. The telescopic guide may comprise three rows of transmittance elements, in which one row has elastic balls, and four rows of transmittance elements, in which two such adjacent rows comprise elastic balls.

Abstract: Cytorhodin S derivatives, especially cytorhodin S-immunoglobulin 
complexes are disclosed.  
     Cytorhodin S itself possesses very high anticancer activity, but 
the complexes act more selectively on cancer cells and 
are more useful as an anticancer agent.  
     In order to produce cytorhodin S-immunoglobulin complexes, the 
oxo group on saccharide chain of cytorhodin S is reduced 
with an alkali metal cyanoborohydride in the presence of an ammonium 
salt or a compound having amino group to be converted to 
amino group or substituted amino group. Then, thus produced cytorhodin 
S derivatives are bound to immunoglobulin by means of a 
bifunctional cross-linking agent, a condensing agent or a 
spacer.  
     New intermediate derivatives are also useful as an anticancer 
agent.
