IPC: C07C33/02
Filed: 1994-01-28
Abstract: PURPOSE:To obtain an anti-osteoporosis agent having a suppressive function against osteoclast formation and excellent in activity and safety by compounding a polyisoprenoide derivative as an effective component. CONSTITUTION:This agent contains a compound of formula I (R is OH, formula II or formula III; waved line is an E-type or a Z-type double bond), e.g. (2E,6E,10 E)-3,7,11,15-tetramethyl-2,6,10,14-hexadecatetraene-1-ol. The agent may be formulated into a preparation, e.g. a powder, a particle, a granule, a tablet, a coated tablet, a capsule, an ointment, a plaster or an injection. A daily dose for an adult is 100-3000mg. The compound of formula I has the suppressive activity against osteoclast formation in a coexistent system of an osteoblast and a spleen cell. In osteoporosis, the balance between bone resorption and osteogenesis is destroyed and the bone resorption is accelerated. As a result, the amount of bone is decreased, bones become fragile and pain is accompanied. Osteoporosis frequently occurs especially in a postmenopausal woman and its treatment continues for a long time. Therefore, the danger of the occurrence of side effects characteristic to female sex hormones is concerned and so as drug is required to have high safety.

Filed: 1988-02-05
Abstract: PURPOSE:To reduce the switching number of a direction sensor and a copy sensor to inhibit the hunting of a moving agricultural machine, by allowing a direction-adjusting control by the copy sensor to precede when the direction- adjusting control by the copy sensor is added during an operating direction control by the direction sensor. CONSTITUTION:When a copy sensor 3 becomes a neutral state having a constant width of deviation amounts at the standard position of the deviation amounts detected by the copy sensor 3 after the direction adjustment of a moving agricultural machine by the copy machine 3, the copy sensor 3 is switched to a direction sensor 4 and the moving agricultural machine is returned in such a direction to become a standard direction preset by the direction sensor 4. But when an adjustment in a reverse direction is carried out during returning the machine in the direction, a direction adjustment by the copy sensor 3 is performed so as to precede. Until the traveling of the moving agricultural machine becomes again a state wherein the copy sensor 3 acts, the switching of the sensor to the direction sensor is controlled so as not to be performed even if the copy sensor 4 becomes neutral.
