  • Patent number: 6024985
    Abstract: The invention provides a synthetic bone precursor material comprising amorphous calcium phosphate and a constituent that inhibits the crystallisation of calcium hydroxyapatite to amorphous calcium phosphate. The synthetic bone precursor may comprise a material of formula CaxMgyPO4 wherein Mg acts as an inhibitor for crystallisation. Other crystallisation inhibitors such as pyrophosphate may be present. The inhibitor is capable of dissolving in physiological saline. Loss of inhibitor from the precursor allows crystallisation of hydroxyapatite. The invention relates to use of a synthetic bone precursor to form bone in vivo, by a transformation of the amorphous precursor material to crystalline hydroxyapatite bone material by the leaching action on inhibitory ions body fluids. it is envisaged that the material will be useful in facilitating bone repair, inducing bone formation or assisting in the attachment of prostheses.

  • Patent number: 5958464
    Abstract: A composition for preventing and treating milk fever in freshening cows, and a method of administering the composition. The basic composition is a mixture of water, calcium chloride, propylene glycol, B vitamins and minerals. The calcium content is lower than conventional calcium treatments used for this purpose. The propylene glycol gives the cow an energy boost and sweetens the taste so the cow does not object to it as it does to conventional gels and liquids. The B vitamins stimulate the cow's appetite. The minerals replace minerals lost in the milk and also help the cow absorb calcium. The composition of the present invention is in a liquid form and is preferably administered using a 200-300 cc drench gun. The end of the dispensing tube of the drench gun is placed between the teeth and cheek of the cow near the receptors that stimulate the esophageal groove reflex.

  • Patent number: 5945129
    Abstract: The invention relates to a process for the production of an infusion or dialysis solution containing bicarbonate and having a physiologically tolerable pH. In order to retain a solution with a stable physiologically tolerable pH even after heat treatment for sterilization, according to the invention, at least 2 mmol/L of at least one carboxylic acid ester is introduced into the solution beforehand. The solution is subjected to heat treatment above 100.degree. C., so that the carboxylic acid ester decomposes almost completely into carboxylic acid and alcohol. The invention further relates to a use of the process according to the invention for the production of a solution for peritoneal dialysis and a medicinal infusion or dialysis solution.

  • Patent number: 5439690
    Abstract: A hazard-free method for controlling insects using a non-toxic composition that kills by dehydration. The invention includes a process for making the composition in the form of crystalline particles which penetrate directly through the exoskeleton of an insect. In operation, the particles work themselves between the insect's protective body plates and then pierce the exoskeleton. Once inside, the particles absorb up to four times their weight of the vital body fluids of the insect. The penetration of the body plates and exoskeleton and/or dehydration ultimately results in death of the insect.

  • Patent number: 5415877
    Abstract: The present invention provides a fungicide composition which contains ingredients which are biocompatible for purposes of agricultural applications, and which are harmless to animals and humans. An invention fungicide composition in the form of a dry blend formulation remains non-caking and free-flowing under storage conditions. Illustrative of an invention fungicide composition is a formulation which has a content of sodium bicarbonate, potassium bicarbonate, xanthan gum, dialkylsulfosuccinate salt and alkyl sulfate salt surfactants, and magnesium silicate anti-caking ingredient. The xanthan gum and surfactants function as an effective spreader-sticker and film-forming medium when the composition is diluted with water for agricultural applications.

  • Patent number: 5366739
    Abstract: A method for prolonged delivery of a therapeutic agent to the eye is disclosed. The method provides for the addition of a desired drug to a suitable, preferably non-aqueous, vehicle. An amount of the vehicle containing a therapeutic dose of the drug is placed on the extraocular skin adjacent to the lateral canthus of the eye. Movements of the orbicularis oculi associated with the scissor-like closing of the lids of the eye continuously transport small portions of the drug containing vehicle into the interpalpebral space where the drug is released to the cornea for intraocular penetration and treatment effected. The method of the invention is particularly effective in delivering insoluble calcium salts for the treatment of dry eye.
