Immunomodulation by tramadol combined with acetaminophen or dexketoprofen: In vivo animal study.

Among other functions, macrophages remove foreign particles, including medications, from the circulation, making them an important target for immunomodulatory molecules. Currently, growing evidence suggests that analgesics affect the activity of immune cells not directly related to pain, and thus may induce unwanted immunosuppression in patients at risk. However, the immunomodulatory effects resulting from macrophage targeting by these drugs are understudied.

Large scale determination of glucosinolates in brussels sprouts samples after degradation of endogenous glucose.

A method was developed for the determination of the glucosinolate content in glucose-rich samples of Brassica vegetables such as Brussels sprouts. Glucose in the samples was enzymatically degraded by the enzyme glucose oxidase (GOD). The resulting hydrogen peroxide and the enzyme GOD were thereafter respectively dissociated and inactivated by a heat treatment at 100 degrees C.

Reduced DNA break formation and cytotoxicity of the topoisomerase II drug 4'-(9'-acridinylamino)methanesulfon-m-anisidide when combined with hyperthermia in human and rodent cell lines.

The interaction between hyperthermia and the anticancer drug 4'-(9'-acridinylamino)methanesulfon-m-anisidide (mAMSA) was studied in the human HeLa S3 and the rodent Ehrlich ascites tumor cell line. For both cell lines it was found that hyperthermia preceding the drug treatment reduced the extent of mAMSA induced DNA breakage as well as mAMSA cytotoxicity. Formation and resealing of mAMSA induced DNA break formation was found to be related to cytotoxicity.

Interaction of hyperthermia and radiation in tolerant and nontolerant HeLa S3 cells: role of DNA polymerase inactivation.

The activities of DNA polymerase alpha and beta were measured in tolerant and nontolerant HeLa S3 suspension cells. The heat-inactivation of the enzymes and their recovery when cells were incubated at 37 degrees C after the heat challenge was compared to the synergistic action of heat and radiation and its disappearance at the level of cell survival. Thermotolerant cells were radiosensitized by heat similarly to nontolerant cells, but the sensitization decreased more rapidly in the tolerant cells when time at 37 degrees C was allowed between the two treatments.
