The raw material for the recalled heparin batches was processed in China from pig's intestines by the American pharmaceutical firm Scientific Protein Laboratories. [1] [2] [3] The U.S. Food and Drug Administration was quoted as stating that at least 81 deaths were believed to be linked to a raw heparin ingredient imported from the People's Republic of China, and that they had also received 785 ...
The standard can be compared visually to a suspension of bacteria in sterile saline or nutrient broth. If the bacterial suspension is too turbid, it can be diluted with more diluent. If the suspension is not turbid enough, more bacteria can be added. McFarland nephelometer standards:{2}
Agar dilution is one of two methods (along with broth dilution) used by researchers to determine the minimum inhibitory concentration (MIC) of antibiotics. It is the dilution method most frequently used to test the effectiveness of new antibiotics when a few antibiotics are tested against a large panel of different bacteria. [1]: 149 [2]
Heparin, also known as unfractionated heparin (UFH), is a medication and naturally occurring glycosaminoglycan. [3] [4] Heparin is a blood anticoagulant that increases the activity of antithrombin. [5] It is used in the treatment of heart attacks and unstable angina. [3] It can be given intravenously or by injection under the skin. [3]
The 6.5% salt broth test is used to analyze the tolerance level of various bacteria under halophilic conditions. This test is used because most organisms cannot survive in high salt concentrations while Staphylococci , Enterococci , and Aerococci are all expected to tolerate 6.5% NaCl concentrations.
WASHINGTON (Reuters) -The first joint meeting of a U.S.-China working group on fentanyl precursor chemicals will be held on Tuesday in Beijing, a senior U.S. official said on Sunday. Deputy ...
Baxter International was founded in 1931 by Donald Baxter, a Los Angeles-based medical doctor, as a manufacturer and distributor of intravenous therapy solutions. [3] Seeing a need for products closer to the Midwest, the company opened a manufacturing plant in Glenview, Illinois, in 1933. [3]
Heparin is an anticoagulant, and if used as a catheter lock solution it could leak into the blood circulation of the patient. Therefore it has been associated with catheter-related bleeding and heparin induced thrombocytopenia (HIT). [8] [9] Citrate catheter lock solutions are being used in three different concentrations – 4%, 30% and 46.7%.
