摘要:
Provided is a sustained-release microparticle preparation of a human growth hormone which combines biodegradability with sustained-release performance while avoiding the use of an organic solvent as much as possible, allows the sustained-release of a human growth hormone over 3 days or more and reduction in the initial burst release, can contain a human growth hormone at 10% or more, can quantitatively adsorb and encapsulate a human growth hormone at up to 20%, and has excellent dispersion and needle penetration properties. A process for producing the sustained-release microparticle preparation of a human growth hormone is also provided. The sustained-release microparticle preparation comprises a porous apatite derivative, a human growth hormone, and a water-soluble divalent metal compound.

摘要:
To provide protein drug sustained-release microparticle preparations for injection that in the production thereof, minimize the use of organic solvents and avoid the simultaneous use of an organic solvent immiscible with water and an aqueous solution and that with respect to the obtained product, simultaneously have in vivo disappearing and sustained-release capabilities, slowly release the contained protein drug at a substantially constant rate over a period of three days or more and realize a drug content of 5% or more, excelling in dispersibility and needle passability; and to provide a process for producing the same. The protein drug sustained-release microparticle preparations for injection comprise a porous apatite or derivative thereof containing a protein drug and, provided thereon by coating or adhesion, an in vivo disappearing polymer.

摘要:
A method and apparatus is described for selecting an entry stored in a data processing system, and specifically a destination in a vehicle navigation system. The system includes a display, a scrolling control having first and second controls, and a selecting control. Using the scrolling control, the user of the system scrolls through a plurality of stored destinations on the display. Each destination is made up of a plurality of alphanumeric symbols, the destinations forming an alphabetically and numerically organized list. The scrolling is accomplished by using the first control of the scrolling control. A character position selector is used to select a character position in a first indicated destination and the second control of the scrolling control is used to jump to subsets of destinations with the next or previous character position as compared to a currently indicated destination. The selecting control is then used to enter a desired destination.
摘要:
A vehicle navigation system displays arrow icons to a driver indicating the directions he must follow from each of one or more turning points on his route to keep the driver from passing inadvertently an intersection in which he must change the vehicle's direction of advance or from turning in an intersection prior to the intersection previously chosen for a turn. Road anomalies, such as sharp curves or U turns are also displayed. The arrow icons are alternatively created from computed directions of the vehicle's advance or stored in an X-Y storage unit from which an arrow icon best fitting the required guidance is selected. The stored arrow icons include straight road, single turns, and multiple turns. The selected arrow is displayed to the driver. An embodiment calculates turns and curves with angles which match the actual angles of the turns, and radii and turning angles of curves.
摘要:
A navigation system mounted on a vehicle computes in advance an optimal route from a starting point to a destination. When the vehicle travels off the optimal route, the navigation system detects an off-route deviation. When an off-route deviation is detected, the system computes a restoration route from the vehicle's present position to a selected point on the optimal route and rapidly displays navigational information to guide the vehicle thereto. Thus there is no need for the system to compute a new optimal route from the present position to the destination, and there is no delay in supplying the driver with navigational information.
摘要:
Mixtures of saturated or unsaturated C.sub.2 -C.sub.5 hydrocarbons are produced by aerobically cultivating a microorganism belonging to a wide variety of genera Fungi, Yeasts, Bacteria and Actinomycetes in a water-containing medium, and recovering the hydrocarbon mixtures from the liquid phase or/and gaseous ambience of the medium. Industrial wastes and various biomass can be employed as nutrient sources in the cultivation.
