The Anaerobic Incorporation of 32P into Adenosine Triphosphate by Hymenolepis diminuta

The anaerobic incorporation of 32P into adenosine triphosphate by Hymenolepis diminuta.

The anaerobic incorporation of 32P into ATP by the tapeworm Hymenolepis diminuta was studied in the presence and absence of uncouplers of oxidative phosphorylation and anticestodal agents. Low concentrations of all compounds tested inhibited this incorporation. Under the anaerobic conditions employed, internal ATP concentrations remained constant in spite of the inhibition of the incorporation ...

Differential glucose incorporation into glycogen by Hymenolepis diminuta.

1. A differential incorporation of 14C-glucose into two distinct molecular weight fractions of glycogen from the tapeworm Hymenolepis diminuta has been observed. Changes in these labeling patterns as a function of the glycogen level have been examined. 2. After incubation of Hymenolepis diminuta in media containing 14C-glucose under steady state conditions of glycogen metabolism, the specific a...

Localization of Glycogen in the Cestode, Hymenolepis Diminuta

Glycogen isolated from the rat tapeworm Hymenotepis diminuta by a mild quantitative procedure exhibits a sedimentation coefficient distribution characterized by two distinct regions of molecular weight with mean S values of 200 X 10-13 cm/dyne, see and 1500 X 10-13 cm/dyne, see respectively (17). This distribution is characteristic for the physiological state of the organism, and differences in...

Thymus dependence of tapeworm (Hymenolepis diminuta) elimination from mice.

Although normal mice eliminated the lumen-dwelling intestinal cestode Hymenolepis diminuta by day 21 post-cysticercoid inoculation, congenitally thymus-deficient (nude) mice maintained their work burdens. Nude mice grafted with thymus glands or injected with thymus cells eliminated their worms.
