Absence of effects of dibutyryl cyclic guanosine 3',5'-monophosphate on release of alpha-amylase, 45Ca efflux, and protein synthesis in rat pancreas in vitro.

Dibutyryl cyclic GMP did not affect basal, or carbachol stimulated secretion of alpha-amylase from rat pancreas. The nucleotide did not have a significant effect on 45Ca release from the pancreas nor did it alter the response to carbachol. The dibutyryl analogue of cyclic GMP did not duplicate or alter the inhibitory effect of carbachol on 3H-leucine incorporation into pancreatic trichloroacetic acid-precipitable protein.

Postnantal cerebellar hypoplasia and dysfunction following methylazoxymethanol acetate treatment (38495).

Swiss albino mice were injected postnatally with 0.05 ul of MAM-ac/g body weight. The mice were sacrificed at 0, 5,10, 15,20, and 25 days. Cerebellar, whole brain and body weights were determined. The treated mice generally showed smaller body weights reflecting the general toxicity of MAM-ac. There was no statistical difference between the whole brain weights of the two groups, when the loss of cerebellar weight was taken into account. Significant differences between the cerebellar weights of control and treated animals were shown at each sacrifice time. It is the conclusion of this study that those differences in weight reflect the destruction induced by MAM-ac during the first 5 days of postnatal life and are not due to a continued degeneration. As for general developmental and behavioral dysfunctions,the treated mice showed delayed eye opening and fur appearance, and by day 25, exhibited a tremorous altered gait.
