اجريت هذه الدراسة للتعرف على مدى تاثير المستخلص المائي الخام للزنجبيل Zingiber officinale Roscoe (الطازج، اوالجاف) على الفئران الحوامل المجرعة عن طريق الفم وبالتراكيز (284، 568، 1136، 1420 ملغم/ كغم) اثناء مراحل الحمل المختلفة (المبكرة والوسطية والمتاخرة | This study was designed to investigate the effect of the crude aqueous extract of ginger (Zingiber officinale Roscoe) (fresh or dry) on pregnant mice orally administered at doses (284, 568, 1136, 1420 mg/kg) during different durations of pregnancy (early, intermediate, and final) for a period of 7 days for each duration. The study showed that there was no significant difference in the average weights of the animals at (P < 0.05) after treatment with (dry or fresh) extract at doses (284, 568, 1136 or 1420 mg/kg) comparing with the control group.The parameters of blood in the early duration of pregnancy showed a significant decrease in the average of hemoglobin (Hb) at (P < 0.05) after treatment with (fresh or dry) extract at the doses (568, 1136, 1420 mg/ kg), while the average of packed cell volume (PCV), demonstrated a significant decrease after treatment with fresh extract at doses (284, 568, 1136, 1420 mg/kg), and at (568, 1136, 1420 mg/kg) after treatment with dry extract at (P < 0.05) : The average of red blood cells (R.B.C.) after treatment with (fresh or dry) ginger extract, at (P < 0.05) showed a significant decrease at doses (284, 568, 1136, 1420 mg / kg), while the average mean corpuscular hemoglobin (MCH), and the average mean corpuscular volume (MCV) at (P < 0.05) revealed a significant increase and at doses (568, 1136, 1420 mg/kg) after treatment with dry extract, at doses (1136, 1420 mg/kg) for the average of (MCH), at doses (568, 1136, 1420 mg/kg) for the average (MCV) after treatment with fresh extract, while the average Mean corpuscular hemoglobin concentration (MCHC) did not show any significant difference at (P < 0.05) after treatment with (fresh or dry) extract comparing with the control group.The parameters of blood in the intermediate duration of pregnancy showed a significant decrease at (P < 0.05) in the average of (Hb), (PCV) and (R.B.C.) at doses (284, 568, 1136, 1420 mg/kg) after treatment with fresh extract, while dry extract demonstrated a significant decrease in average of (Hb) and (PCV) at doses (568, 1136, 1420 mg/kg), and a significant decrease in the average of (R.B.C.) but at doses (284, 568, 1136, 1420 mg/kg), while the average of (MCH) and (MCV) showed a significant increase at (P < 0.05) and at doses (568, 1136, 1420 mg/kg) after treatment with (fresh or dry) extract, while the average of (MCHC) did not showed any significant difference at (P < 0.05) after treatment with (fresh or dry) extract comparing with the control group.The parameters of blood in the final duration of pregnancy revealed a significant decrease (P < 0.05) in the average of (Hb), (PCV) and (R.B.C.) at doses (284, 568, 1136, 1420 mg/kg) after treatment with (fresh or dry) extract, while (MCH) showed a significant increase at (P < 0.05) and at doses (568, 1136, 1420 mg/kg) after treatment with (fresh or dry) extract, (MCHC) did not demonstrated any significant difference at the level (P < 0.05) after treatment with (fresh or dry) extract at all doses, while (MCV) showed a significant increase at (P < 0.05) and at doses (284, 568, 1136, 1420 mg/kg) after treatment with fresh extract, and at doses (568, 1136, 1420 mg/kg) after treatment with dry extract comparing with the control group. The results showed a significant decrease at (P < 0.05) in the average of diameters of ovarian and corpus luteum after treatment with (fresh or dry) extracts in the early and final durations of pregnancy at doses (568, 1136, 1420 mg/kg), and in the intermediate duration after treatment with (fresh or dry) extract but at doses (284, 568, 1136, 1420 mg/kg) comparing with group control.As for the concentration of the hormone estrogen (? - estradiol) didn’t demonstrated a significant difference at (P < 0.05) during different durations of pregnancy after treatment with (fresh or dry) extract at all doses, whereas progesterone showed a significant decreased at doses (284, 568, 1136, 1420 mg/kg) in all durations after treatment with (fresh or dry) extract comparing with the control group. Using doses at (284, 568, 1136, 1420 mg/kg) with (fresh or dry) extracts revealed a significant increase at (P < 0.05) in the average number of infected follicles in the all durations of pregnancy comparing with the control group. The results showed that there are no significant difference in the lengths of the embryos during intermediate and final durations at (P < 0.05) after treatment with (fresh or dry) extract at all doses comparing with the control group.There are also histopathological changes in the ovary, uterus and placenta included degeneration in ovarian follicles, necrosis, congestion, hemorrhage, edema, vasodilatation and rupture in blood vessels at different using doses.These findings indicated that the treatment with (dry and fresh) extract at doses (568, 1136 or 1420) mg/ kg harmful on pregnancy in different durations (early, intermediate, and final) , also the using of fresh ginger more harmful than dry ginger.
