Background: Xenoestrogens are defined as chemicals that mimic some structural parts of the physiological estrogen compounds, therefore may act as estrogen or could interfere with the actions of endogenous estrogens. Phytoestrogens (plant estrogens) are substances that occur naturally in plants. They have asimilar chemical structure to our own body’s estrogen. Vitamin C, also known as ascorbic acid, is used to prevent and treat scurvy. Objective: The aim of the study was to clarify the effect of both bisphenol-A (BPA) and liquorice together on some sexual hormones and illustration of the effect of vitamin C on their actions. Materials and methods: Thirty male albino rats were used and divided into three groups: Group I: control (untreated group), Group II: rats treated with BPA and liquorice, Group III: rats treated with BPA and liquorice in addition to vitamin C. Blood samples were collected for different biochemical investigations. Results: The biochemical results showed high significant increase (p<0.01) in the activities of ALT, AST, urea, creatinine, FSH, prolactin, total cholesterol, triglycerides, LDL-C, VLDL, LDL/HDL and TC/HDL levels. There was high significant decrease (p<0.01) in HDL-C, total protein, albumin, globulin, testosterone, and LH. These results turned back to the normal values after receiving the vitamin C as compared to normal group. Conclusion: it could be concluded that phytoestrogen and xenoestrogen had undesirable effects and it's recommended to minimize the utilizing of these compounds to protect people from its hazardous effects.

Background: Xenoestrogens are a type of xenohormone that imitates estrogen. They can be either synthetic or natural chemical compounds. Synthetic xenoestrogens include some widely used industrial compounds, such as PCBs, bisphenol A (BPA) and phthalates. "Dietary estrogen" is also called phytoestrogen, which is a plantderived xenoestrogen not generated within the endocrine system, but consumed by eating phytoestrogenic plants. Stem cell enhancer (SCE) (StemEnhance®) is a novel mobilizer of bone marrow adult stem cells that was shown to increase the number of circulating stem cells. Objectives: The aim of the current work was to clarify the effect of both BPA and liquorice together on some sexual hormones and illustration of the effect of stem cell enhancer on their actions. Materials and methods: Thirty male albino rats were used and were divided into three groups: Group I: control (untreated group), group II: rats treated with BPA and liquorice and group III: rats treated with BPA and anise oil in addition to stem cell enhancer. Blood samples were collected for different biochemical investigations. Results: There was a highly significant increase (p < 0.01) in the level of ALT and AST activities, urea, creatinine, FSH, prolactin, total cholesterol, triglycerides, LDL-C, VLDL, LDL/HDL and TC/HDL. While, there was highly significant decrease (p < 0.01) in HDL-C, total protein, albumin, globulin, testosterone and LH. These results turned back to the normal values after receiving the SCE as compared to normal group. Conclusion: It could be concluded that phytoestrogen and xenoeostrogen have undesirable effects and it is recommended to minimize the utilization of these compounds to protect people from its hazardous effects.

Background: Xenoestrogens are chemically distinct industrial products potentially able to disrupt the endocrine system by mimicking the action of endogenous steroid hormones. Phytoestrogens are naturally occurring non-steroidal plant chemicals that can act like the female hormone estrogen. Arctium lappa (burdock) root has traditionally been recommended as an aphrodisiac agent. Objective: The aim of the study was to clarify the effect of both bisphenol-A (BPA) and anise oil together on some sexual hormones and illustration the effect of A. lappa on their actions. Materials and methods: The study was conducted on thirty male albino rats. The animals were divided into three groups: Group I, control untreated group, Group II, rats treated with bisphenol-A and anise oil and Group III, rats treated with BPA and anise oil in addition to A. lappa. Blood samples were collected to estimate biochemical parameters. Results: The biochemical results showed highly significant increase (p < 0.01) in the activities of ALT, AST, urea, creatinine, FSH, prolactin, total cholesterol, triglycerides, LDLC, VLDL, LDL/HDL and TC/HDL levels. While, there was highly significant decrease (p < 0.01) in HDLC, total protein, albumin, globulin, testosterone and, LH. All these results turned back to the normal values after receiving the A. lappa as compared to normal group. Conclusion: it could be concluded that phytoestrogen and xenoestrogen have undesirable effects and it's recommended to minimize the utilization of these compound to protect people from its hazardous effects.

Background: Xenoestrogens are compounds like estrogens in effect but not in structure which are mimicking the action of endogenous estrogen and activate estrogen receptor. Phytoestrogens are naturally occurring non-steroidal plant chemicals that can act like the female hormone estrogen. Aphanizomenon Flos-aquae (AFA) is a blue-green microalgal species which has antioxidant properties. Objective: The aim of the study was to clarify the effects of both Bisphenol A (BPA) and anise oil (phytoestrogen) together on some sexual hormonal pattern in male albino rats and illustration of the adverse effects of AFA on their actions. Materials and methods: Thirty male albino rats were used. They were divided into three groups: Group I: control (untreated group), Group II: rats treated with BPA and Anise oil and Group III: rats treated with BPA and Anise oil in addition to AFA. Blood samples were collected for different biochemical investigations. Results: The biochemical results showed highly significant increase (p<0.01) in the activities of ALT, AST, urea, creatinine, FSH, prolactin and lipid profile (total cholesterol, triglycerides, HDL-C, VLDL, LDL/HDL & TC/HDL). While, there was a highly significant decrease (p < 0.01) in LDL-C, total protein, albumin, Globulin, testosterone and LH. These results returned back to the normal values after receiving the AFA as compared to normal group. Conclusion: It could be concluded that phytoestrogen and xenoestrogen have undesirable effects and it is recommended to minimize the utilization of these compounds to protect people from its hazardous effects.

Objective: Oxidative stress is induced by bisphenol A (BPA) and affects many organs. Vitamin E is an effective antioxidant which prevents the activity of free radicals. This study was aimed to clarify the effect of vitamin E on the oxidative stress induced by chronic administration of BPA. Materials and methods: 30 female albino rats were divided into 3 groups (10/each); group1: control rats, group 2: rats treated with bisphenol A (20 mg/ kg.B.wt) for three months, and group 3: rats treated with bisphenol A (20 mg/kg.B.wt) for three months, then treated with BPA and vitamin E (0.57/100 g B.wt) for other 15 days. Results: BPA induced hormonal disrupt in liver and kidney dysfunctions and hyperlipidemia. Vitamin E ameliorated all these parameters. Conclusion: since we exposed to many harmful disruptions and oxidative stress compounds, we must take vitamin E as a protective agent. [ABSTRACT FROM AUTHOR]

Background: bisphenol A (BPA) is a worldwide used endocrine disruptor that is incorporated in many plastic industries. The exposure of human to such substances starts early during the fetal life, postnatal life and extends throughout the life of the individual. Many agencies raised warnings against the excessive use of such substances. The aim of the present work was to evaluate the extent to which BPA can affect the first generation (of parents treated with the same compound, during pregnancy and lactation), which treated with the same compound during their life time. Materials and Methods: group 1: 15 control female rats. Group 2: 15 female rats of the first generation treated with BPA (20mg/kg b.wt) for one month. Sexual hormones, liver and kidney functions were measured. Results: BPA induced increase in breast and ovarian tumor markers. It also showed significant increase in estrogen, FSH, prolactin, and progesterone. It is also increased liver function, kidney function, lipid profile. In the same time it leads to decrease in LH, HDL, and protein levels. Conclusion: BPA induced toxicity, which is mediated by oxidative stress. This study ringing the bells of danger for using such compounds. [ABSTRACT FROM AUTHOR]

Background: Bisphenol A (BPA) is a worldwide used endocrine disruptor that is incorporated in many plastic industries. Exposure of humans to such substance starts early during the fetal life, postnatal life, and extends throughout the life of the individual. Many agencies raised warnings against excessive use of such substance. Aim of the work: This study aimed to investigate effects of the recovery period (RP) and stem cell enhancer (SCE) on the female albino rats which received BPA. Materials and Methods: This study was performed on forty female albino rats with an average body weight of 140-160 grams. Animals were divided into four groups (10 rats per cage); group I (control untreated for 30 days), group II (BPA treated for 15 days, and then sacrificed), group III (BPA treated first for 15 days, then left for another 15 days without any treatment "RP"), and group IV (BPA treated first for 15 days, then treated with SCE for another 15 days). The following biochemical analyses were done to all groups; ALT (alanine amino-transferase), AST (aspartate amino-transferase), GGT (gamma glutamyl-transferase), total proteins, albumin, globulins, A/G ratio [i.e., liver function tests], creatinine, A/C (albumin/creatinine) ratio, uric acid [i.e., renal function tests], total lipids, total cholesterol, LDL-C (low density lipoprotein cholesterol), HDL-C (high density lipoprotein cholesterol), and triglycerides [i.e., lipids profile]. Results: In the BPA treated rats (group II) the biochemical results showed highly significant increases (P<0.01) in the enzymatic activities of ALT, AST, GGT, creatinine, uric acid, total lipids, total cholesterol, LDL-C, and triglycerides levels, with only a significant increase (P<0.05) in globulins levels when compared to the control group. On the other hand, there was highly significant decreases (P<0.01) in total proteins, albumin, A/G ratio, A/C ratio, and HDL-C levels when compared to the control group. These results turned back to about the normal control values after stopping the use of BPA and either taking a RP (group III) or receiving the SCE (group IV). Conclusions and Recommendations: It could be concluded that BPA has dangerous toxic effects on the liver and kidney functions as well as on the lipids profile. So, we recommend minimizing utilization of this compound (BPA) as possible to protect people from these hazardous effects. Moreover, the RP (i.e., 15 days without treatment) is better than the use of SCE which has no more benefit against the antitoxic effects of BPA. [ABSTRACT FROM AUTHOR]
