  • Patent number: 6537566
    Abstract: The proliferation of uterine fibroid leiomyoma cells is inhibited by certain Fibroid Cell Growth Inhibitor (FGI) agents. The pharmacological doses of these FGI agents in the milieu of uterine fibroid cells can be made high enough to not only inhibit proliferation, but to also causes cell death. Non-invasive or minimally invasive, non-systemic delivery methods are used to deliver the FGI agent to the milieu of the target fibroid leiomyoma cell population, thereby avoiding the disadvantages and side effects of surgical and systemic hormonal therapy interventions in the treatment of uterine fibroids. The FGI agents are substrates that are normally present or are well tolerated in the human body. The efficacy of the FGI agents appears to be related to their ability to moderate the Protein Kinase C and Mitogen Activated Protein Kinase pathways. Specific FGI agents shown to be useful to inhibit growth or proliferation of uterine fibroid cells include: &agr;-tocopherol, &agr;-tocopherol succinate, and troglitazone.

  • Patent number: 6375971
    Abstract: Solid dose ballistic projectile for medicating animals which comprises a biologically compatible projectile casing which defines an interior cavity having a wall with a frictionally engagement enhanced surface. A medicament payload, slightly oversized with respect to the cavity, is forced into the cavity engaging the frictionally-enhanced cavity surface for a tight, secure fit. The bullets are of improved accuracy and can be successfully implanted into the flesh of an animal with greater reliability.

  • Patent number: 6331308
    Abstract: Controlled release devices are shaped and placed in locations through which insects and/or other cold blooded animals generally enter an area or a structure sought to be protected. The controlled release devices include a polymeric matrix and a pesticide contained in the matrix. The pesticide is gradually released out of the matrix to the surface of the device. The pesticide on the surface of the device kills the intruding insects or other cold blooded animals that come in contact with the pesticide. In addition, if the device is in contact with a permeable structure or object, the pesticide released onto the surface of the device is absorbed by such permeable structure or object to provide a barrier to entry by the insects and/or other cold blooded animals.
