TL;DR: Four days after giving 16 mumol estradiol-17 beta (E2) per 100 g body weight to male Japanese quail, the thyroids of these quail accumulated twice as much 125I as did the thyROids of control quail.

TL;DR: In vitro kidney production of 1,25-(OH)2D3 was increased significantly compared to control levels treated with sodium acetate, and lead treatment had no significant effect on plasma calcium and inorganic phosphate levels.
Abstract: Immature female Japanese quail were given either lead acetate or sodium acetate in the drinking water for 15 days. In vitro kidney production of 1, 25- and 24-25- dihydroxyvitamin D3 from tritiated 25-hydroxyvitamin D3 was measured. At all 3 dose levels of lead acetate (0.32, 3.2 and 32 mg Pb/ml), in vitro kidney production of 1,25-(OH)2D3 was increased significantly compared to control levels treated with sodium acetate. Lead treatment had no significant effect on plasma calcium and inorganic phosphate levels.

TL;DR: Results indicate a relatively important function of NADP-isocitrate dehydrogenase for NADPH-production even under DL-ethionine toxicity and suggest complicated relationships between egg production and activities of enzymes associated with carbohydrate and lipid metabolism in quail liver.
Abstract: The effect of dietary DL-ethionine and/or DL-methionine on egg laying, and activities of some NAD linked-dehydrogenases and NADPH-producing enzymes in liver of Japanese quail, Coturnix coturnix japonica was investigated. A 0.30% DL-ethionine plus 0.30% DL-methionine supplemented diet reversed partially the egg laying inhibited by the diet with 0.30% DL-ethionine alone. No inhibitory effect on egg laying was observed for the diet supplemented with 0.30% DL-methionine alone. In marked contrast to the decreased activity of L-glycerol 3-phosphate dehydrogenase and malate dehydrogenase, significantly increased activity of lactate dehydrogenase was obtained for quail fed the DL-ethionine, and the DL-ethionine plus the DL-methionine supplemented diet, respectively. No marked changes in activities of these three dehydrogenases were obtained for quail fed the diet supplemented with DL-methionine alone. Although decreased activity was observed for all of the four NADPH-producing enzymes in quail fed the diet supplemented with DL-ethionine alone, the DL-ethionine plus DL-methionine, the smallest decrease was obtained for NADP-isocitrate dehydrogenase. The diet supplemented with DL-methionine alone induced markedly the respective activity of malic enzyme and glucose 6-phosphate dehydrogenase. These results indicate a relatively important function of NADP-isocitrate dehydrogenase for NADPH-production even under DL-ethionine toxicity and suggest complicated relationships between egg production and activities of enzymes associated with carbohydrate and lipid metabolism in quail liver.

TL;DR: O,p′-DDT injected into adult castrated male quail stimulated growth of the proctodeal (foam) gland, indicating that this pesticide constituent, in addition to its known estrogenic actions, is also androgenic.
Abstract: O,p′-DDT injected into adult castrated male quail (Coturnix coturnix japonica) stimulated growth of the proctodeal (foam) gland, a structure that is androgen but not estrogen responsive, indicating that this pesticide constituent, in addition to its known estrogenic actions, is also androgenic.
