Patent number: 6537566Abstract: 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.Type: GrantFiled: March 8, 2000Date of Patent: March 25, 2003Inventors: John Alton Copland, Steven L.

Patent number: 6352690Abstract: An effective and gentle formulation for the treatment and prevention of pseudofolliculitis barbae and skin irritation and method for the application of same is provided herein. In its preferred embodiment, the formulation consisting essentially of a petroleum balance containing 10% to 20% camphor, 5% fragrance oil and 1% to 2% mineral oil. The formulation is designed to prevent the razor bumps associated with pseudofolliculitis barbae without the use of harsh chemical compounds while allowing the user to continue to use a traditional method of shaving. The formulation is applied through a method consisting of shaving normally with a razor, application of a thin veneer of the formulation to the shaved area and removal of the formulation by means of a wet washcloth or other means.Type: GrantFiled: April 17, 2000Date of Patent: March 5, 2002Inventor: Alfonso A. Shabazz
