Abstract: Assembly or kit which is adaptable to an ordinary manually driven wheelchair, comprising one or two devices comprising a guide (1) provided with quick attachment means, a wheel slide (15) having a transverse bearing for a rear wheel which rotates between an advanced position and a retracted position, in which the rear wheel does not project beyond the side of the seat, an articulated elongate lever (28) having snap-fitting elements (23, 25) which are spaced apart by a distance equal to the distance between the advanced and retracted positions, and which can be snap-fitted with a complementary snap-fitting element (10) in these positions, and a means (10) for holding the lever in a non-snap-fitted position, the movement of the slide (15) releasing it automatically from the holding means (10).

Abstract: A new preparation for regenerating tissues or healing wounds, which can be administered to a patient, which comprises serum and globin being insoluble at physiological pH, said preparation being obtained by adding said serum to said globin being insoluble at physiological pH.

Abstract: Preparations comprising, especially, globin that is insoluble at neutral pH, and therefore at physiological pH, in which the globin has been obtained from whole blood by depigmentation in a medium that extracts or dissolves the haem but leaves the globin and the other constituents of proteinic nature in a substantially undissolved state, a process for the production of those preparations, and uses, especially for the filling, healing or regeneration of tissues, especially for chronic wounds and osseous healing or regeneration.
