Abstract: The present invention relates to novel growth hormone-releasing peptides and method for increasing the release of growth hormone levels in mammals, as well as method for increasing milk production in dairy cows and increasing growth rates of animals, such as cattle, sheep, swine, and others. The novel peptides of this invention surprisingly are effective for releasing growth hormone levels in animals by replacing the natural amino acids in positions 1, 2, 3, 8, 9, 10, 12, 21 and 27, as well as derivatizing the N-terminal amino acid residue in human pancreatic islet tumor origin growth hormone-releasing factor.

Abstract: An improved process for preparing carbon fibers in a gaseous phase reaction comprising introducing a gas mixture comprising at least one carbon compound, at least one inorganic transition metal compound gas and at least one carrier gas into a reactor and subjecting the mixture to a temperature of 600.degree. C. to 1300.degree. C. in the reactor for inducing growth of carbon fibers.
