Thyroxine (T4) in a dose of 0.1 microgram per g body weight caused in the rat a significant increase in hepatic glucose-6-phosphatase activity, while a reduction of this enzyme activity was observed after 1 microgram of T4 per g. The hepatic glycogen content was found to be depleted and a marked elevation in protein, RNA and DNA contents were observed after both doses of T4.

The effects of thyroxine (T4) on hepatic glucose-6-phosphatase activity and glycogen content in toad (Bufo melanostictus) and Lata fish (Ophicephalus punctatus) were studied in order to show the difference, if any in the enzyme activity and glycogen metabolism in their liver. Thyroxine injections (1 microgram/g) for five consecutive days caused a reduction in hepatic glucose-6-phosphatase activity and glycogen content in toads of immature, juvenile and adult stages. In contrast, Lata fish of different stages showed an enhancement of hepatic glucose-6-phosphatase activity after T4 treatment (1 microgram/g, 5 injections). The liver glycogen content in Lata fish of different age groups was found to be reduced after T4 injections, but not so much as in the toad.

An investigation was made to evaluate the role of Convolvulus pluricaulis root extract in the regulation of hyperthyroidism in female mice. Its possible site of action was also studied. L-Thyroxine treatment for 30 days increased serum concentrations of thyroxine (T4) and triodothyronine (T3). The activity of hepatic 5'-monodeiodinase (5'-DI) and glucose-6-phosphatase (G-6-Pase) was also enhanced. On the other hand, administration of the plant extract either alone or with L-T4, decreased serum T3 concentration and the activity of hepatic 5'-DI and G-6-phase, without marked alteration in hepatic lipid peroxidation, indicating the possible regulation of hyperthyroidism by the plant extract. It appears that the action of the plant extract on thyroid function is primarily mediated through the inhibition of 5'-DI enzyme activity.
