Background: Acrylamide has been reported to induce hepato-and nephrotoxicity. The present investigation aims to alleviate the dangerous effects at the histopathological and physiological levels of acrylamide by bee venom and its extracted bradykinin-potentiating factor (BPF). Seventy-five adult male mice were divided into 15 groups: a control (G1) 15 animals for 30 (G1.1), 45 (G 1.2), and 60 (G 1.3) days of experimental periods; acrylamide-administered G2.1, G2. 2, and G2.3 received acrylamide orally (10 mg/kg b.w) daily for 30, 45, and 60 days. Chips-administered G3.1, G3.2, and G3.3 were fed one third of its daily diet by chips for 30, 45, and 60 days. Bee venom-and BPF-treated G4.1 and G4.2 were i.p. injected with bee venom (1.319 mg/kg b.w.) and BPF (2.314 mg/kg b.w.), respectively, day after the other day for 60 days. G5.1 and G5.2 received acrylamide orally (10 mg/kg b.w) combined either with i.p. by bee venom (1.319 mg/kg b.w.) or BPF (2.314 mg/kg b.w.) respectively day after the other day for 60 days. G6.1 and G6.2 were fed one third of its daily diet by chips for 60 days combined either with i.p. by bee venom (1.319 mg/kg b.w.) or with BPF (2.314 mg/kg b.w.), respectively, day after the other day for 60 days. Results: The results showed that acrylamide administration and chips feeding groups suffer from alteration and histopathological changes in liver and kidney tissues that were accompanied with the increase in liver and kidney physiological biomarker (ALT, AST, urea, creatinine, uric acid) and the decrease in the albumin levels. Acrylamide or chips combined with either bee venom or BPF showed improvement in the level of physiological and histopathological studies. Conclusion:The study concluded the protective role of bee venom and its extracted BPF against acrylamide-and chips-induced hepato-and nephrotoxicity.

Background: Acrylamide is reported for its toxicity on the central and the peripheral nervous system and causes paralysis. Bee venom (BV) and bradykinin-potentiating factor (BPF) have been documented for their potential therapeutic effects as anti-neuroinflammation. The study aimed to ameliorate the neurotoxic effects of acrylamide or chips by using BV or its extracted BPF. Mice were divided into 15 subgroups: control (G1.1, G1.2, G1.3) at 30, 45, and 60 days, respectively; acrylamide-(10 mg/kg b.w.; orally daily) administered subgroup for 30 days (G2.1), 45 days (G2.2), and 60 days (G2.3); chips feeding group (1/3 of daily diet) for 30 days (G3.1), 45 days (G3.2), and 60 days (G3.3); bee venom-treated group for 60 days (1.319 mg/kg b.w.) (G4.1); BPF-treated group for 60 days (2.314 mg/kg b.w.) (G4.2), day after the other day; and acrylamide-or chips-administered groups combined either with BV (G5.1, G6.1) or BPF treatment (G5.2, G6.2) for 60 days. Results: The results indicated that the approximate LD50 for BV and BPF equal to 13.19 mg/kg and 23.14 mg/kg, respectively, and the extracted BPF contains 15 amino acids. Also, the results showed abnormal gait in mice of acrylamide-administered groups which was accompanied by histopathological changes in the hippocampus, cerebellum, and cerebral cortex. A marked gradual increase of alpha-synuclein expression was noted at the studied region in the acrylamide-and chips-treated groups at 60 days of treatment as compared to control. Both BV-and BPF-treated groups either separately or in co-administration with acrylamide or with chips did not show any histopathological changes in the studied regions with downregulated expression of alpha-synuclein. Conclusion: The study concluded the neuroprotective effect of BV and its extracted BPF against neurotoxicity induced by acrylamide or chips administration.

Background Animal venoms have been known as a source of drugs beneficial to human health. Accordingly, this study was designed to determine the effect of bradykinin potentiating factor (BPF) separated from honey bee venom, Apis mellifera on histological structure, thyroid and male sex hormones of the thyroid gland and testis in a model of hypothyroid male white rats induced by carbimazole. Results This study includes male rats divided into 6 main and sub-groups (10 rats in each group). Control group, carbimazole group, levothyroxine group, BPF group, carbimazole group treated with levothyroxine and carbimazole group treated with BPF. At the end of experiments (60 days) rats were sacrificed and dissected; the blood was collected for determination of thyroid and male sex hormones. Also, the thyroid gland and testis were taken to histological study. The results indicated that, carbimazole group showed a highly significant decrease in thyroid hormones (T4, T3, Ft4 and Ft3) and male sex hormones (LH, FSH and testosterone), but a significant increase in TSH compared to control group. The results revealed that, treated groups with levothyroxine or BPF have significant increase in thyroid and male sex hormones and significant decreasein TSH. A significant improvement was detected in co-treated groups (hypothyroid groups) with levothyroxine or (BPF). Also, the present study showed a histopathological change in thyroid gland and testis of hypothyroid male rats. Conclusion Treated hypothyroid rats with levothyroxine as a drug and BPF as a natural product showed an improvement of these complications induced by carbimazole in thyroid gland and testis. Therefore, BPF may be benefical in treatment of hypothyroidism.

Background Gibberellic acid (GA3) is a plant growth regulator used to improve the quality of crops but its residues in food causes many hazardous effects. In contrast, olive oil has registered several health benefits including antioxidant, anti-inflammatory, and anti-cancer. Thus, the present study suggests the use of olive oil as a natural food source to counteract the GA3 toxicity during mice development. In a preliminary experiment, 18 mature females were classified into control and GA3-treated subgroups with ascending doses of GA3 (55, 110, 240, 480, 960 mg/kg B.W.) for 2 weeks. In the main experiment, 20 pregnant females at the 7th day of gestation were divided into four groups: G1 is control, G2 treated orally with GA3 (55 mg/kg), G3 treated with olive oil, and G4 treated with GA3-olive oil. The pregnant females were dissected at prenatal stages at E14 and E18 of gestation. Results The high doses of GA3 in the preliminary experiment showed decrease of uterine folds, reduction of carbohydrates content and TNFR2 expression of the uterine glands, degeneration of the ovarian follicles, blood vessels congestion, and altered TNFR2 expression in oocyte membrane as compared with the control. In the second experiment, GA3-treated embryo at E14 and E18 revealed histopathological changes and altered TNFR2 immunostaining in the developing liver, kidney, and skin tissues. Treatment of GA3 with olive oil improves the negative effects induced by GA3. Conclusion The study concluded that a supplementation rich diet with olive oil creates a protective effect against gibberellic acid-induced embryotoxicity during pregnancy.

Breast cancer is the most common malignancy accounting for 38.8% of all malignancies among Egyptian women. This study aimed to investigate the A. muricata leaves extract and its active fraction in inhibiting cell proliferation in the human MDA-MB-231 cell line as a model of Triple Negative Breast Cancer. MDA-MB-231 cell lines were seeded and maintained in RPMI 1640 culture medium. RNAs were isolated from non-treated MDA-MB-231 and treated cell lines with A. muricata DMSO extract after 72 hrs incubation using TriPure isolation reagent. qRT-PCR was applied to measure the gene expression of P53, and Bcl2 against the β-actin gene as an internal control. Protein analysis of BRCA1, BRCA2, EGFR, p53, Bcl2, Cytochrome C, and Caspase3 gene expression was carried out by ELIZA immunoassay. The level of expression of the pro-apoptotic P53 gene in the treated cell line with A. muricata DMSO extract was overexpressed, indicating its potential efficacy in directing cancer cells toward programmed death. On the other hand, the treated cell line significantly (P = 0.05) showed low expression of BRCA1, BRCA2, and EGFR when compared to the negative control. The present study revealed that A. muricata leaves extract is a promising inhibitor of cell proliferation in the MDA-MB-231 cell line (TNBC), and has efficacy against BRCA1, BRCA2, and EGFR gene expression. Since this plant is widely consumed by humans and is non-toxic, it could be developed quickly for chemoprevention and intervention in breast cancer patients.
