  • Publication number: 20110071146
    Abstract: To provide a novel and excellent method for treating and/or preventing prostatic cancer, benign prostatic hyperplasia, acne, seborrhea, hirsutism, baldness, alopecia, precocious puberty, adrenal hypertrophy, polycystic ovary syndrome, breast cancer, lung cancer, endometriosis, leiomyoma and the like based on selective inhibitory activity against 17?HSD type 5. It was found that an N-sulfonylindole derivative, where the indole ring is substituted by a carboxy group, a carboxy-substituted lower alkyl group or a carboxy-substituted lower alkenyl group at its carbon atom, has potent selective inhibitory activity against 17?HSD type 5 and may become a therapeutic agent and/or preventive agent for benign prostatic hyperplasia, prostatic cancer and the like without accompanying adverse drug reactions due to a decrease in testosterone, and the present invention has thus been completed.

  • Patent number: 6585420
    Abstract: To provide a wheel support bearing assembly having a capability of detecting the number of revolutions of a wheel, having no risk of breaking of wire outside a vehicle body, capable of reducing the weight and cost of an automotive vehicle. This wheel support bearing assembly for rotatably supporting a wheel 13 relative to a vehicle body structure 12 includes an outer member 1 having its inner periphery formed with plural rows of raceways 6 and 7, an inner member 2 having raceways 8 and 9 confronting respectively to the raceways 6 and 7, and rows of rolling elements 3 accommodated respectively between the raceways. An electric generator 4 for generating an electric power as one of the outer and inner members 1 and 2 rotates relative to the other of the outer and inner members 1 and 2. A signal indicative of the number of revolutions of the wheel 13 outputted from the electric generator 4 is transmitted wireless by mean of a wireless transmitting means 5A.
