Granted: 1996-05-28
Abstract: Thermotherapeutic pad A flexible heat pad for heat transfer to a person's limb. The pad consists of a fabric (preferably cotton) envelope enclosing a load of cereal grains, preferably oats. Preferably, the water content of the oat is precisely monitored to remain within the 9 to 14 % range by weight of the oat total weight. The quantity of oat grains inside the cotton envelope must be such as to provide even oat distribution within the cotton envelope enclosure, after deformation, whereby localized grainless pockets within the pad enclosure are substantially prevented. The pad is pre-heated for about two minutes inside a micro-wave oven, at full power setting, before use. Thermal inertia of the oat thereafter allows continuous heat dlffusion to the limb for about half an hour. The pad may alternately be put into the freezer for at least four to six hours, to thereafter diffuse cold to the swollen limb part of a mammal.

Title: Liposomal antibiotic formulation
Inventor: SHEK PANG N
IPC: A61K9/127
Filed: 1994-03-04
Granted: 2000-10-03
Abstract: The drugs of choice for treating intra-abdominal sepsis caused by infection with Gram negative bacteria include .beta.-lactams such as cefoxitin. However, unless the drugs are administered within 8 to 12 hours post-infection, the infecting microbes rapidly gain entry to and reside in cells of the reticuloendothelial system, where the microbes appear to become shielded from further drug action. It has been found that a liposomal cefoxitin formulation is effective in reducing the bacterial counts and the mortality of animals suffering from intra-abdominal Gram negative sepsis. The preferred liposome is phosphatidylcholine and phosphatidylserine in the molar ratio of from 9.5:0.5 to 1:1.
