Temporal changes in glucose transport capacity in excysted scoleces of Hymenolepis diminuta were examined. Assays involved incubation for 1 min in [3H]glucose after pre-incubation for 1 min to 8 h in saline. There were two abrupt increases in uptake velocity, a relatively small one between 15 and 75 min, and a large one between 5 and 6 h, during which the Vmax increased from 0.36 to 2.49 nmol/25 larvae/h. The second increase was unaffected when the pre-incubation saline contained 5 mM glucose… 
Biochemical characterization of Cysticercus tenuicullis in Iranian Fat- tailed sheep
The present study was designed to evaluate the biochemical profiles of C. tenuicollis in sheep slaughtered at the main abattoir of Shiraz and the supernatants were analyzed for various biochemical parameters.
Detection some chemical and biochemical constituents of Cysticercus tenuicollis cyst fluid of Iraqi goat
The decrease or increase in the chemical and biochemical SE values provide the preventive role of the parasite Cysticercus tenuicollis cysts membrane to exchange these substances.


Ontogenetic changes in helminth membrane function.
In the Cestoda, the uptake of monosaccharides and amino acids is described for Hymenolepis diminuta and the transfer of amino acids, sugars and macromolecules across the membranes of hydatid cysts and protoscoleces is described.
Allosteric control of pyrimidine transport in Hymenolepis diminuta: an unusual kinetic isotope effect.
Differences in kinetics between initial uptake and substrate concentration of either thymine or uracil and absorption kinetics of methyl-14C- and 3H-labelled substrates were hyperbolic indicate that the sigmoidal kinetic effect of pyrimidine transport in this organism is an isotopic effect associated with the presence of the 14C label at the 2 position in the pyridine ring.
Hymenolepis diminuta : protein synthesis in cysticercoids
Uptake and incorporation of leucine by stage III cysticercoids exceeded that of stage V metacestodes and the 10-day-old adult worm and incorporation was apparently linear over a 5 h period in contrast to uptake which was non-linear over the same time.

Maturation of the scolex syncytium in the metacestode of Hymenolepis diminuta , with special reference to microthrix formation
The adult-type surface is formed by 3 days post-scolex retraction, coinciding with the earliest time that the metacestode is infective to the final host.
