Abstract: A pharmaceutical aqueous suspension formulation for parenteral administration having substantially stabilized pH, comprising a biologically active compound and a pH controlling effective concentration of L-Methionine.

Abstract: A direct reduction device (10) of the gravitational type to obtain iron carbide starting from iron oxide, comprising a reduction and carburation reactor (12) below which a cooling and passivation container (26) is arranged wherein the iron carbide is suitable to be cooled and passivated, between the reactor (12) and the container (26) a valve for solids (24) is interposed suitable to regulate the transfer of the iron carbide.

Abstract: Fume intake and cooling device for intake conduits (11,111,211) in electric arc furnaces (26a,26b), comprising a containing structure (28) associated at one end (12) with an aperture on the roof of the furnace and connected at the second end (13) with an intake and filter system (27), the containing structure (28) having, in cooperation with its inner sidewalls, cooling means, the cooling means comprising a pipe (14), which is spiral shaped and has turns (16) lying on a plane substantially at right angles to the longitudinal axis of the conduits (11,111,211), the turns (16) being distanced with respect to each other in such a way as to form interstices (20) between adjacent turns (16), the interstices (20) through which the fumes pass serving to anchor the slag.

Abstract: The present invention relates to bioadhesive starches, to a process for their preparation and to pharmaceutical compositions containing them. It also relates to the use of such bioadhesive starches as carriers for the administration of a drug.

Abstract: The present invention provides a pharmaceutical composition comprising an estramustine derivative and a cyclodextrin, particularly in the manufacture of a medicament suitable for the oral administration of an estramustine derivative to a patient suffering from a tumor.Estramustine derivatives according to the invention are, for example, compounds of general formula (I) ##STR1## wherein R is ##STR2## in which R.sub.1 is C.sub.1 -C.sub.4 alkyl and n is 0, 1 or 2, and the pharmaceutically acceptable salts thereof.

Abstract: A pharmaceutical composition comprising a drug and a dehydrated cyclodextrin having improved dissolution properties, and the process for the preparation thereof.

Abstract: A novel milk coagulating enzyme is produced by cultivating a yeast of the group Cryptococcus albidus and its variants aerius and diffluens on a culture medium containing assimilable carbon, nitrogen and trace nutrients at a temperature between 15.degree. C. and 40.degree. C. under aerobic conditions, and at a pH of between 3.0 and 8.0. The enzyme is recovered from the culture medium, for example, by salting-out, dialyzed and freeze-dried. The preparations obtained are characterized by high milk-clotting activity with very low proteolytic activity.
