Abstract: In a process for promoting regenerating of bone marrow there is administered to a mammal in need thereof an effective regeneration promoting dose of an aqueous solution of stabilized oxygen in a matrix of chlorite ions.

Abstract: An aqueous solution of a chemically stabilized chlorite matrix for intravenous and perioperative administration in a dosed amount of 6.2.times.10.sup.-6 mole of ClO.sub.2 -- to 9.3.times.10.sup.-5 mole of ClO.sub.2 -- per kg of body weight to humans and animals is described.

Abstract: A portable wirefeed and control apparatus for use in consumable electrode arc welding systems which is capable of being powered by conventional AC or DC variable voltage or variable current supplies without modification of the power supply or the wirefeed and control apparatus. The portable wirefeed unit incorporates a wirefeed motor, a supply of weld wire, optional gas controls, and voltage regulating and protective control circuits all powered at welding arc voltage carried by the welding current supply conductor. The unit is circuit connected to the power supply by means of a single welding electrode supply conductor and a ground return. Electrode power, weld wire, optional shielding gas supply and welding gun control switch conductors are carried in a single flexible conduit extending between the control unit and a remote welding gun and wirefeed speed and thus wirefeed rate are partially responsive to variations in welding arc voltage.
