A bioactive material is disposed on one or more of the needles, whereby movement of the head operates to pick up the bioactive material and to deliver a portion of the bioactive material to a selected location, the selected location being a dermis, or an epidermis, or both the dermis and the epidermis. In more particular embodiments, the bioactive material is a macromolecule substance that is part of a group of substances, the group consisting of a protein, a vitamin, a gene, a growth agent, a drug, and a peptide. The needles create an injury that triggers collagen production from one or more fibroblasts in the skin.

A planter for the mechanized planting of sea oats in beach or other difficult planting areas. The planter includes a calibrator that automates the release of sea oat plants through various release tubes as the planter moves over a chosen planting area. The calibrator controls the release of each plant at re-selected distances. Growth agent is introduced through ancillary mechanisms either through the release tubes or just behind each tube. A plow in front of each release tube creates a furrow into which each plant is deposited, and a series of grates are strategically positioned to control the reflow of planting soil back into each furrow after release and to then smooth any remaining soil adjacent the filled in furrow. The planter is towed behind a tractor through nominal hitches, and a chair and planting support rack is provided for an operator positioned in the center of the planter.

A method of propagating mammalian endodermally derived progenitors such as hepatic progenitors, their progeny, or mixtures thereof is developed which includes culturing mammalian progenitors, their progeny, or mixtures thereof on a layer of embryonic mammalian feeder cells in a culture medium. The culture medium can be supplemented with one or more hormones and other growth agents. These hormones and other growth agents can include insulin, dexamethasone, transferrin, nicotinamide, serum albumin, β-mercaptoethanol, free fatty acid, glutamine, CuSO4, and H2SeO3. The culture medium can also include antibiotics. Importantly, the culture medium does not include serum.The invention includes means of inducing the differentiation of the progenitors to their adult fates such as the differentiation of hepatic progenitor cells to hepatocytes or biliary cells by adding, or excluding epidermal growth factor, respectively.The method of producing mammalian progenitors is useful in that the progenitors can be used subsequently in one or more of the following processes: identification of growth and differentiation factors, toxicological studies, drug development, antimicrobial studies, or the preparation of an extracorporeal organ such as a bioartificial liver.

The present invention is directed to methods and compositions for treating pulmonary disease comprising delivering directly to a patient's lungs a therapeutically effective amount of oxybutynin in combination with one or more pharmaceutically effective agents. Oxybutynin may be selected from the group consisting of, but not limited to, a xinafoate salt, a palmitate salt, a pamoic salt, a resonate salt, a laurate salt and other salts. The pharmaceutically effective agents comprise bronchodilators, antiinflammatories, corticosteroids, corticosteroid reversal agent or alveolar growth agents or other agents selected from proteinase or protease inhibitors.

The invention discloses a preparation method of polyacrylamide with an ultrahigh molecular weight. The method comprises the following steps of: adding a mixed monomer aqueous solution of acrylamide and sodium acrylate, a chain growth agent, an aid and a composite initiator into a polymeric kettle; introducing high-purity nitrogen for performing adiabatic copolymerization; and granulating, drying and smashing to obtain an anionic acrylamide copolymer with an ultrahigh relative molecular mass. By adopting the method, no hydrolytic reagent is added in a polymerizing process, so that harmful gases such as carbon dioxide, ammonia gas and the like are not produced, and environmental pollution is avoided.

The invention provides kitasamycin microcapsule and a preparation method and application thereof, which pertains to a feed drug additive field, in particular relates to novel kitasamycin preparation and a preparation technique thereof, and the application thereof in the preparation of livestock and poultry antibiotic growth promoter. The kitasamycin microcapsule of the invention comprises the kitasamycin and medical auxiliary materials; the weight of the medical auxiliary materials is 2-16 times of that of the kitasamycin material; the microcapsule is prepared through mixing the kitasamycin with heated and melted medical auxiliary materials and spray cooling. The kitasamycin microcapsule eliminates the bitterness of kitasamycin, intensifies the delayed release function of kitasamycin, reduces the stimulation of the kitasamycin to the stomach and the damage and decomposition degree thereof in the stomach, and enhances the effective intestines concentration and the functioning time of kitasamycin; the method for preparing the kitasamycin microcapsule is a wholly close manufacturing process and a wholly close material conveying system, thus decreasing flying of dust and material loss with has high yield of the products.
