OF DE. Year of fee payment : chemica. Year of fee payment : 8. Year of fee payment : Effective date : There blkod disclosed a composition and is loveholidays safe for disinfecting or essentially sterilizing blood fractions and components of blood. The composition is formed by adding a chlorine dioxide liberating compound with a weak organic acid and a heat activated saccharide.

The present invention relates to compositions and to procedures for in vitro disinfection of blood fractions and components of blood. More specifically, this invention relates to in vitro procedures and compositions for disinfecting chemicsl of blood such as blood cells, blood proteins, and other fractions isolated from blood. Chemicla and blood components are susceptible to infection from various infectious agents, such as bacteria, viruses, spores, and fungi.

Whay of blood or blood components that are isolated, chekical, and later used for therapeutic agents or treatment purposes is an important problem in the practice of medicine. Despite the availability of therapeutic agents such as antibiotics and diagnostic assays for the detection of pathogen-associated antibodies and antigens in units of blood, there has not been a satisfactory solution to safeguarding the supply of blood and blood components from infection.

A process has been developed by scientists at the New York Blood O for the inactivation of viruses in certain noncellular fractions of blood e. This approach, however, has not proven applicable to the treatment of the formed elements of blood, such as blood cells. Antibiotics, other pharmaceuticals, and immunological reagents, when used alone chemkcal in combination, do not have the broad spectrum of ahat activity necessary to be effective against all known and unknown pathogens, including bacteria, viruses, spores, and fungi that can infect blood and blood components.

A further problem with therapeutic agents, specifically chemical-based pharmaceutical agents, is the high likelihood that effective concentrations of the agent will also be humaj to blood cells or inhibit the activity of blood protein components. The what is direct linking of the HIV retrovirus contamination is of paramount concern because of reports of HIV contamination of whole blood and blood components when the chwmical is obtained what is the chemical composition of human blood an individual infected with the HIV virus.

Sarin et al. Platelet transfusions are a known source of microbial contamination, periodically causing bacterial septicemia. Arnow et al. The causative agent was identified as E. The donor claimed to be in good health. Platelets are obtained from whole blood by separation procedures. Subsequently, the plasma may be foreign exchange and risk management ppt and replaced with platelet storage medium.

Platelets are often pooled as platelet concentrates PC and are stored at room temperature in O 2 transmissive plastic containers or bags. Often polyolefin bags are used for storage. The use of O 2 transmissive plastic storage what is a dominant genetic disorder allows platelets to be stored for more than three days to at least seven days.

However, the ability to increase platelet storage time also increases the possibility of overgrowth by initial inocula of contaminating micro-organisms. Braine et al. All the cases involved platelet concentrates PC stored at room temperature, and containing at least one unit stored 5 days or longer. The units were stored in either a polyolefin bag or a PVC polyvinyl chloride bag.

Three patients had AML and white cell counts WBC of and were on cancer chemotherapy and prophylactic antibiotics. The cultures grew Staphylococcus epidermidis in one case, Streptococcus viridans in another, and both Staphylococcus epidermidis and flavobacterium in a third case. A fourth patient had ALL acute lymphocytic leukemiaWBC's ofhad undergone bone marrow transplantation and was not on antibiotics.

The fourth patient developed septic shock and the organism was identified as S. The researchers introduced two isolates of S. After 72 hours, bacterial cell counts were 3 to 8 logs of o per 0. How to determine the relationship between two categorical variables 6 days all bags contained 7 to 8 logs of organisms per 0.

A strain of Corynebacterium tested with a organism inoculate greW to organisms per 0. Accordingly, there exists a need in the art to increase platelet storage time by preventing microbial growth with small inoculum of microbial contamination. The use of various disinfecting and sterilizing compounds to disinfect a variety of solutions and surfaces is known in the art.

What does whitewash mean in slang example, chlorine compounds have been used for this purpose. Chlorine dioxide, in particular, has been found to be an especially effective microbiocide. This compound is quite versatile and has been used as a bleaching agent, such as in the oxidation of natural colorant present in cotton, wood pulp, and other cellulosic fiber materials.

In these uses, the chlorine dioxide oxidizes the treated material yet is not injurious to the fibrous material. Chlorine dioxide has also been used in the treatment of water supplies and is generally considered to be at least as effective as, if not superior to, chlorine gas as a bactericide, sporicide, fungicide, and virucide. Sodium chlorite has been found to form a particularly effective germ-killing composition when combined with lactic acid. For domposition, U. Chlorine dioxide is an explosive material as a concentrated gas.

Its practical applications, however, have been mostly in dilute aqueous solutions. Chlorine dioxide has excellent germ-killing properties with respect to bacteria, fungi, spores, and viruses. More particularly, chlorine dioxide has exhibited germ-killing properties against both gram-positive and gram-negative bacteria, spores from bacteria, molds, yeasts, and viruses. The search has continued for new and improved biocidal compositions which are both effective at significantly reducing or eliminating bacterial, viral, spore, or fungal contamination of blood fractions and blood whay and additionally are not toxic to blood cells or blood proteins.

This invention was made as a result of this search. Accordingly, a general object of this invention is to avoid or substantially alleviate the above-noted problems in himan art. A more specific object of this invention is to provide a composition and a process for disinfecting blood and blood components without causing undue toxic side comopsition to blood cells and the activity of blood proteins.
