Background: Achillea millefolium, (Asteraceae) is flowering plant which is popularly known as yarrow. It has been used in folk medicine to treat complaints such as inflammation, pain, wounds, hemorrhages and gastrointestinal disturbances. Objectives: To study the histological changes in uterus and reproductive hormones in female mice delivered to mothers treated with Achillea extract during pregnancy. Materials and Methods: Seventy pregnant female mice at age of six weeks were used as a model for this study. The animals were divided into two groups: control (C) (35), and experimental (G) (35) groups. The experimental group was given 1.5 mg/kg alcohol extract of Achillea millefolium dissolved in 1ml distilled water orally for the whole pregnancy, while the (C)was given distilled water only in the same amount and for the same period of time. The number and the body weight of the delivered offspring was recorded, in addition the endometrial thickness, the number and diameter of the uterine glands was measured in the histological sections at puberty. In addition evaluation of FSH, LH and E2 hormones levels were done. Results: The results of this study showed highly significant (p<0.01) decrease in the litter size of the experimental compared to the control group, as well as significant decrease (p<0.05) in the weight of the offspring, the endometrial thickness, the number and diameter of the uterine glands in the (G) compared to the (C). Conclusions: Consumption of low dose Achillea millefolium causes significant decrease in number and weight of the offspring, in addition to its effect on the uterus of the delivered female offspring.
Monosodium glutamate (MSG) is a widely used flavor enhancer in many foods. However, excessive consumption during pregnancy may adversely affect embryonic development and reproductive functions. This study aimed to investigate the effects of maternal MSG consumption during pregnancy on pregnancy outcomes and the reproductive system of female offspring in mice. Thirty adult pregnant female mice, aged 42–49 days, were used in this study. The animals were equally divided into two groups: an experimental group (G1) and a control group (G2). The experimental group received MSG extract orally at a dose of 1 mg/kg body weight dissolved in 1 ml of distilled water (D.W.) throughout the three weeks of pregnancy, whereas the control group received 1 ml of distilled water alone for the same duration. After delivery, litter size and litter weight were recorded. Forty days after birth, the weights of the female reproductive organs were measured, and the diameters of the ovaries and oviducts were assessed. In addition, blood samples were collected for the evaluation of follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estradiol (E2) levels in both groups. The experimental group showed a significant reduction in litter size and a significant decrease in litter weight compared with the control group. Female offspring born to MSG- treated mothers also exhibited a significant decrease in reproductive organ weight, ovarian diameter, and oviduct diameter. Furthermore, significant reductions in the levels of FSH, LH, and estradiol were observed in the experimental group. Maternal consumption of MSG during pregnancy may negatively affect pregnancy outcomes and impair the development and function of the reproductive system in female offspring.
Lead is a heavy metal toxicant, present widely in the environment and workplaces. Zinc has been shown to reduce the toxicity of lead. The present experimental animal study was designed to observe the changes in the testes due to excessive use of lead. This study aims to detect the effect of antioxidants (zinc) on the toxicity of high doses of lead on the reproductive organs of male mice embryos compared to the control group as a model for human representative. Thirty mature female mice were used (Swiss-Webster), as a mammalian model. They were divided into three groups, 10 mice/group after labelling them. They were randomly assigned into three experimental groups, and these embryos were processed for histological observations. The recorded results showed a severe disruption in the organization of testicular structure with primordial germ cells severely degenerated with the absence of basal lamina and peritubular myoid cells of the treated group (G1) compared with the control group at day 14 and day 17. The embryo testes of (G2) at day 14 showed irregular testes cords with prominent degenerative changes compared to that of the control group (G3). It was concluded from these results that zinc sulphate plays a significant role in the improvement of histological damage of the testes belonging to mothers injected with lead acetate and protects the reproductive organs from injury during lead toxicity.
