ToxicologicalImpact ofExposure to 2,3,7,8- tetrachlorodibenzo-p-dioxin (TCDD) on Some Hormonal Profiles and Hematological Parameters in Goats
2014
Female Baladi goats were used to investigate the toxicological effects of 2,3,7,8 tetrachlorodibenzo-p-dioxin (TCDD) on some serum hormones andblood features. Animals were divided into two groups, group 1: served as control, group 2: animals were orallyadministeredwith three repeated doses (0.23µg/Kg body weight) of TCDD with 2 days intervalbetween dosing. Results revealed that exposure toTCDD induced reduction in serum estradiol, progesterone and prolactin levels and elevation in glucocorticoid hormone cortisol throughout the different studied periods (48h, 96h and 16 days commenced the last intoxicated dose). The adverse impact of TCDD on goat reproductive hormones was confirmed by histopatholgical observations on their uteri and ovaries after 16 days commenced the last intoxicated dose. Intoxication of goats with TCDD showed also marked decreases in hemoglobin (Hb) concentrat ion, red blood cell count (RBC) , packed cellvolume (PCV), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) OriginalResearch Article
