The activities of biogenic amine deaminating enzymes, monoamine oxidase (MAO), types A and B, copper-zinc superoxide dismutase (CuZnSOD) and hydrogen peroxide (H2O2) scavenging enzyme, catalase, were studied in the hypothalamus of rats treated with dexamethasone (DEX) and corticosterone (CORT) for 2 and 7 days. Only chronic treatment (7 days) with both(More)
Changes in fitness components including larval stage duration, relative growth rate (RGR), and mass of the gypsy moth, Lymantria dispar L. (Lepidoptera: Lymantriidae), were investigated in caterpillars fed a synthetic diet with or without a cadmium supplement (10, 30, 100, 250 microg Cd/g dry food weight). Morphometric changes of large protocerebral(More)
The uteri, spontaneously active or Ca(2+) (6 mM) induced, were allowed to equilibrate, and to inhibit voltage-gated potassium (K(V)) channels 1 mM 4-amino pyridine (4-AP) was applied for 15 min before adding H(2)O(2). H(2)O(2) was added cumulatively: 2 μM, 20 μM, 200 μM, 400 μM, and 3 mM. Average time for H(2)O(2) concentrations (2, 20, 200, and 400) μM to(More)
Previous results in this laboratory indicate that protamine sulfate (PS) evokes dose-dependent relaxation of both spontaneous and calcium ion-induced uterus activity mediated predominantly by potassium channels and, to a small extent, via β-adrenergic receptors or nitric oxide (NO)-dependent pathways. Indometacin is a nonselective inhibitor of(More)
