An injection syringe including a device for preparation of an injection in situ, useful to the injection which is liable to suffer chemical changes if left for a long time in the state of solution or dispersion ready to inject. The injection syringe is portable by a patient who may prepare a necessary injection in situ with the use of a device included in the syringe which will automatically perform an injection with a prescribed dosage. The injection syringe includes a device for preparation of an injection, whereby mechanical impacts affecting the medicine and consequently, chemical changes with a medicine would be minimized during the step of dissolving the medicine. The syringe as noted is especially useful for preparation of injection and injection of human growth hormones, interferon and various polypeptides which are of an environmentally sensitive nature and liable to suffer chemical changes if left for a long time in the state of solution or dispersion.

A readily-soluble freeze-dried solid preparation of hGH with a minimal content of degradation products in terms of deamidation, dimers, polymers, and sulphoxide forms, obtainable by a method comprising a single lyophilization of an aqueous slurry of an amorphous hGH isoprecipitate, the slurry having a pH of from about 4.7 to 5.0 and being essentially free of buffer components other than acetate.

The disclosed composition exhibits various skin conditioning effects, such as acne treatment, wrinkle improvement, dark spot removal, skin elasticity improvement, hair growth stimulation, skin aging prevention, skin moisturization and the proliferation of skin epidermal stem cells.

Macromolecular drug complexes containing a protein therapeutic, like human growth hormone, and an excess stoichiometric molar amount of a polymer, like heparin, and compositions containing the same, are disclosed. Compositions containing the macromolecular drug complexes are administered, including via pulmonary delivery, to individuals suffering from a disease or condition, and the complexes release the protein therapeutic, in vivo, to treat the disease or condition.

The present invention relates generally to the production, purification, and isolation of human growth hormone (hGH). More particularly, the invention relates to the production, purification, and isolation of substantially purified hGH from recombinant host cells or culture medium including, for example, yeast, insect, mammalian and bacterial host cells. The process of the present invention is also useful for purification of hGH linked to polymers or other molecules.

A method for selecting novel proteins such as growth hormone and antibody fragment variants having altered binding properties for their respective receptor molecules is provided. The method comprises fusing a gene encoding a protein of interest to the carboxy terminal domain of the gene III coat protein of the filamentous phage M13. The gene fusion is mutated to form a library of structurally related fusion proteins that are expressed in low quantity on the surface of a phagemid particle. Biological selection and screening are employed to identify novel ligands useful as drug candidates. Disclosed are preferred phagemid expression vectors and selected human growth hormone variants.

The present invention relates to protease resistant mutants of human growth hormone, which contain newly introduced proteolysis resistant mutations and N-linked or O-linked glycosylation site(s), such that these recombinantly produced polypeptides have glycosylation patterns distinctly different from that of the naturally occurring human growth hormone. The polynucleotide coding sequences for the mutants, expression cassettes comprising the coding sequences, cells expressing the mutants, and methods for producing the mutants are also disclosed. Further disclosed are pharmaceutical compositions comprising the mutants and method for using the mutants.

Formulations of modified human growth hormone polypeptides are provided.

A chemically modified human Growth Hormone (rhGH) prepared by attaching a transient linker which comprises a polyethylene glycol. The chemically modified protein may have a much longer lasting rhGH activity than that of the unmodified rhGH, enabling reduced dose and scheduling opportunities and the modified rhGH may not cause lipoatrophy. Also includes methods of use for the treatment and / or prevention of diseases or disorders in which use of growth hormone is beneficial.

The present invention relates to dosage forms of human growth hormone, the use of an absorption enhancer to allow absorption of human growth hormone into the systemic circulation in a biologically active form, in particular after oral administration, as well as the use of oral dosage forms comprising human growth hormone and an absorption enhancer for the treatment of human growth hormone deficiencies and disorders associated therewith.

The invention is a bio-modified recombinant growth hormone (rhGH) complex and preparing method, making glutamine residue-containing rhGH react with amino donor polyethylene glycol alkyl amine PEG or monomethoxypolyethylene glycol (mPEG) under the catalysis of transglutaminase (mTG), to make acylamide in gamma-bit of the glutamine residue and amino in primary amine bit of the amino donor form an amido bond, thus obtaining it, namely PEG-rhGH or Mpeg-rhGH. It has high biostability and long in vivo half life, applied to prepare permanent injection drugs or develop oral drugs.

The present invention relates to probiotic microorganisms producing chimeric human growth hormone for oral use and methods for preparing them. The invention provides probiotic Lactobacillus or yeast transformant expressing chimeric protein which is human growth hormone fused with Fc fragment of human IgG, in which the transformants are safely delivered into intestine though oral route. Also, the invention provides a chimeric protein-expressing vector which can induce transcytosis in intestine epithelial cells. Accordingly, the invention demonstrates that the chimeric protein for oral delivery system can be absorbed in intestine, and delivery of the chimeric protein by oral route using Lactobacillus has very excellent efficiency in vivo test in rats. Accordingly, the Lactobacillus of the present invention is an excellent deliverer of protein drugs.

PCT No. PCT / JP96 / 01225 Sec. 371 Date Mar. 27, 1998 Sec. 102(e) Date Mar. 27, 1998 PCT Filed May 9, 1996 PCT Pub. No. WO97 / 12631 PCT Pub. Date Apr. 10, 1997Drug which contains human growth hormones capable of recovering the renal function when administered to a patient who has renal insufficiency but has not yet undergone kidney dialysis. By administrating the drug, the loss of renal function represented by an extreme decrease in creatinine clearance or the reciprocal of blood creatinine level can be prevented and thus it can dispense with the dialytic treatment for patients with renal insufficiency.
