چکیده
Min.mg konstant. Für die Aktivität des aus den Wurzeln erhaltenen Digipurpurogenins berechnet sich ein Wert von etwa 4200 Imp./Min. gleich 3,5-10"2% der eingesetzten Aktivität. Für das gesamte Digipurpurogenin ergibt sich damit eine Einbaurate von etwa 0,1 Prozent. Als weitere Metaboliten wurden in den Blättern nach Hydrolyse Digitoxigenin und Gitoxigenin nachgewiesen, während diese Substanzen unter den Metaboliten in der Wurzel völlig fehlten. Im einzelnen wurden in den verschiedenen Fraktionen folgende Aktivitäten gemessen (in Imp./Min.) :

متن کامل[Methyl-14C]-choline incorporation into nude mice bearing tumor xenografts-correlation with [methyl-3H]-thymidine: A pilot study
Background: Many in vitro studies suggested that choline incorporation into many types of tumors is related to cell proliferation. Whether in vivo choline incorporation is related also to cell proliferation or not was my question. Therefore, the aim of this pilot study was to investigate the relationship of in vivo [methyl- 14C]-choline incorporation and in vivo [methyl-3H]- thymidine incorpora...
متن کاملPathways of glycogen synthesis from glucose during the glycogenic response to insulin in cultured foetal hepatocytes.
The pathways of glycogen synthesis from glucose were studied using double-isotope procedures in 18-day cultured foetal-rat hepatocytes in which glycogenesis is strongly stimulated by insulin. When the medium containing 4 mM-glucose was supplemented with [2-3H,U-14C]glucose or [3-3H,U-14C]glucose, the ratios of 3H/14C in glycogen relative to that in glucose were 0.23 +/- 0.04 (n = 6) and 0.63 +/...

The synthesis of NAD and NADP by rat adipose tissue was measured in vitro. Nicotinamide-7-14C and NaHPP04 were incorporated together into NAD with a =P/14C ratio of 1.82 and nicotinic-7-14C acid and NaH232POa with a ratio of 1.94. Nicotinic acid stimulated, by 90%, lipogenesis from glucose-UW by rat adipose tissue in vitro. Glucose plus insulin and refeeding for 48 hr after a 48 hr fast markedl...
متن کاملO-16: Metabolism of Exogenous Fatty Acids, Fatty Acid-Mediated Cholesterol Efflux, PKA and PKC Pathways in Boar Sperm Acrosome Reaction
Background: For understanding the roles of fatty acids on the induction of acrosome reaction which occurs under association of cholesterol efflux and PKA or PKC pathways in boar spermatozoa, metabolic fate of alone and combined radiolabeled 14C-oleic acid and 3H-linoleic acid incorporated in the sperm was compared, and behavior of cholesterol and effects of PKA and PKC inhibitors upon fatty aci...
