Current Trends in Applications of Circulatory Microchimerism Detection in Transplantation

Primarily due to recent advances of detection techniques, microchimerism (the proportion of minor variant population is below 1%) has recently gained increasing attention in the field of transplantation. Availability of polymorphic markers, such as deletion insertion or single nucleotide polymorphisms along with a vast array of high sensitivity detection techniques, allow the accurate detection of small quantities of donor- or recipient-related materials. This diagnostic information can improve monitoring of allograft injuries in solid organ transplantations (SOT) as well as facilitate early detection of relapse in allogeneic hematopoietic stem cell transplantation (allo-HSCT). In the present review, genetic marker and detection platform options applicable for microchimerism detection are discussed. Furthermore, current results of relevant clinical studies in the context of microchimerism and SOT or allo-HSCT respectively are also summarized.

[Development and investigation of preparations containing kitasamycin and flumequine]

Swine dysentery and poultry cholera are very harmful animal diseases which cause great damage. Flumequine and kitasamycin are new and up-to-date preparations for the treatment of these diseases. ++ Imequyl ad us. vet. and ++ Trubin ad us. vet. are the registered medicines. The doses are 7 mg flumequine and 21 mg kitasamycin/body weight kg. The drug technological problem is that flumequine does not dissolve sufficiently in water. It dissolves well at pH = 10, but kitasamycin is unstable at this pH. It was hoped that these two components would together act as agonists, and that kitasamycin would promote the dissolution of flumequine. An injection preparation and a powder mixture for dissolution were developed. Chemical interaction between the components was conformed by IR and NMR measurements.
