Rat parietal cells were incubated for 2 h with pertussis toxin (100 ng/ml) which ADP-ribosylates and inactivates guanine nucleotide regulatory proteins (G proteins) of the 'Gi-like' family. The effect of this pretreatment on the action of inhibitors of parietal cell acid secretion was investigated by using the accumulation of the weak base aminopyrine as an(More)
The adenine nucleotide profiles (AMP, ATP, NAD and NADH2) of peripheral blood lymphocytes isolated from patients with common variable hypogammaglobulinaemia (CVH) were similar to those in control cells. AMP and ATP levels were also similar in the lymphocytes of patients with chronic lymphatic leukaemia (CLL). Since CVH and CLL patients have reduced activity(More)
Many captive animals are fed diets that are drastically different in mechanical properties than their wild diet. Most captive pantherines are fed a nutritionally supplemented diet consisting almost entirely of ground meat. While many zoos supplement this diet with bones, the fact remains that large captive felids are fed diets that require substantially(More)
