Patent number: 6231889Abstract: The components of this invention are chosen because of their complementarity for the prevention or treatment of diseases caused by the herpes simplex virus. L-Lysine favorably increases the physiologic immunomodulation necessary for defense against this virus. Zinc improves and maintains a normal immune response. 2-Deoxy-2-D-glucose and heparin sodium alter the surface interaction between the herpes virus and the cell, preventing fusion and infectivity. N-Acetyl-L-cysteine increases glutathione levels thereby creating a thiol redox barrier to the virus at the cell membrane. Quercetin reduces intracellular replication of the herpes virus and viral infectivity. Ascorbate, in concert with copper and D-&agr;-tocopherol, provides an antioxidant defense against the herpes virus, which tends to lose latency during period of oxidative, free radical excess. Selenium and quercetin also participate in reducing various oxidative stresses.Type: GrantFiled: September 15, 1999Date of Patent: May 15, 2001Assignee: ChronoRX, LLCInventors: Kenneth T.

In this temperature range, the deposit is cold enough for the required therapeutic effect, but not so cold as to cause pain or tissue damage. The choice and proportion of thickening agents used are selected to provide a deposit that does not flow or spread. Were the deposit to spread, it would present a large surface area from which propellant present in the deposit would evaporate rapidly.Type: GrantFiled: March 30, 1999Date of Patent: April 10, 2001Assignee: OMS Holdings LLCInventors: Lloyd I.

Patent number: 6211393Abstract: Silicon compound of general formula a), in which A, B, C, D are radicals which are different from OH and are covalently bonded to Si; two or three of these bond that are linked to Si are Si—O—C, Si—S—C or Si—N—C type bonds and are hydrolyzable in vivo, forming Si—OH bonds that are biologically active especially when in contact with living tissue, the A and D bonds of formula b) being invariably hydrolyzable; at least one of the hydrolyzable bonds corresponds to an acyloxy, aryloxy or vinyloxy radical; at least one of the compounds obtained after hydrolysis of the hydrolyzable bonds is a stabilizer, and the non-hydrolyzable bonds, which are of the Si—C type, correspond to hydrocarbon or fluorocarbon radicals for which Si is not directly linked to the phenyl ring.Type: GrantFiled: July 22, 1996Date of Patent: April 3, 2001Assignee: Exsymol S.A.M.Inventors: Marie Christine Seguin, Jean Gueyne, Jean-Francois Nicolay, Andre Franco

Patent number: 6203804Abstract: An external skin-care composition comprising (A) a low-strength agar having a jelly strength of 250 g/cm2 or lower as measured at an agar concentration of 1.5 wt. %; (B) a water-soluble polymer; (C) a cooling agent; and (D) water. The external skin-care composition has a high cooling effect, a feeling of coolness and excellent stability.Type: GrantFiled: October 28, 1998Date of Patent: March 20, 2001Assignee: Kao CorporationInventors: Chie Murakado, Kazuhiro Yamaki

Patent number: 6200557Abstract: A solution or gel composition containing activated stabilized chlorine dioxide and phosphates, such as disodium hydrogen phosphate, sodium dihydrogen phosphate, trisodium phosphate, and sodium monofluorophosphate, is disclosed for destroying HIV. The preferred concentration ranges are between about 0.005%-2.0% chlorine dioxide, and between about 0.02%-3.0% phosphate. The phosphate compound retards escape of chlorine dioxide in the pH range of 6.0 to 7.4, at which pH stabilized chlorine dioxide becomes activated and releases sufficient chlorine dioxide to reduce motility and become lethal to the involved micro-organisms. Using a lubricant as a vehicle for the chlorine dioxide/phosphate composition; development of vaginal itching due to Candida Albicans will be stopped.Type: GrantFiled: October 14, 1999Date of Patent: March 13, 2001Inventor: Perry A.
