Abstract The effects of sex hormones, glucocorticoids, folate and protein deprivation upon tetrahydrofolate dehydrogenase activity in mammalian tissues were studied. In male rats estradiol induced significant increase in the activity of jejunal tetrahydrofolate dehydrogenase but only a slight increase occurred in the jejenum of hormone-treated female

Tetrahydrofolate Dehydrogenase Cytochemistry and Classification of Acute Leukaemia
Acta Haematologica, 1982Bone marrow and blood smears from patients with acute lymphoblastic and myeloblastic leukaemia prior to therapy were stained for tetrahydrofolate dehydrogenase. Compared with other cytochemical tests this reaction seems to discriminate clearly between cells with myeloid and lymphoid features.

Two different methods, one proposed by us (1969, 1970) and the other by Onicescuet al. (1970), for the histochemical demonstration of tetrahydrofolate dehydrogenase have been compared using as test materials frozen sections of mouse liver and blood smears of laboratory animals that had been infected experimentally with malaria.

The bifunctional dehydrogenase/cyclohydrolase domain of the human NADP-dependent trifunctional methyleneH4folate dehydrogenase/methenylH4folate cyclohydrolase/formylH4folate synthetase (H4folate = tetrahydrofolate) catalyzes two sequential reactions involved in the interconversion of H4folate derivatives.

Some general aspects in cytochemical demonstration of the tetrahydrofolate dehydrogenase, concerning the final reaction product, are studied. Steady and variable factors are detected in a comparative study of Vertebrate hemopoiesis: the enzyme exhibits peculiar features in different cell types.

In vitro studies were made on four synthetic polymeric derivatives of the antitumor agent methotrexate (MTX): 1) divinylether-maleic anhydride-MTX (DIVEMA-MTX), 2) poly-L-lysine-MTX (PL-MTX), 3) polyethyleneimine-MTX (PEI-MTX), and 4) carboxymethyl cellulose-MTX (CMC-MTX).

Important ecological und economic functions are performed by different pollinators. Apis mellifera being one of the most important ones, as it is managed by beekeepers worldwide. In recent years, the obligate ectoparasite Varroa destructor grew of importance as the impact on honey bee hives grew more apparent, as research has shown that it not only ...
