This study aimed to evaluate the anticancer activity and cell division arresting by dandelion methanolic extract on breast cancer cell line MCF-7 cancer cell line. For achieving this goal, cytotoxicity assay (MTT assay), multipara system assay: High Content Screening (HCS) which include (viable cell count VCC; membrane permeability MP; cellular mitochondrial permeability CMP; nuclear intensity NI and cytochrome C releasing ), reactive oxygen species detection and cell cycle phases division were tested. The results of this study showed the ability of the plant to reduce cancer cell viability in a dose-dependant manner within IC50 (141.0) in comparison to IC50 of (334.4) on the human normal cell line (WRL-68). Furthermore, the results of HCS demonstrated the ability of plants to enhance apoptosis of cancer cells and increase the production of ROS from cancer cells treated with plant extract and doxorubicin drug in comparison with negative control (50.07±2.2, 53.03±2.6 vs. 44.77±1.4) respectively. Also,  the results of the cell cycle for control, 400 µg\ml of dandelion extract and doxorubicin drug showed the ability to arrest the division of cancer cells at G1 phase by decreasing its transmission to S, G2, and M phases of the cell cycle (62%, 59% and 62.46% at G1) (27.46%,26.50% and 24.66% at S Phase) (16.50%, 20.50% and 18.46% at G2\M) respectively. All these effects are attributed to the active compounds (secondary metabolites) such as terpenes, polyphenols, and different minerals that possess anticancer activity against different cell lines like MCF7.

Achillea millefolium (Asteraceae) is a permanent herb highly recognized in traditional medicine for its anti-oxidant and anti-inflammation properties. However, studies on phytochemical constituents of A. millefolium underlying these properties are scarce. The present work focuses on examining the effect of methanol extract of A. millefolium L. on total and differential blood cells account on albino male mice. The results showed the methanol extract increased the account of lymphocyte, and monocyte cells, and total account as well as this extract showed high decrease in the oxidative stress of MTX after the interfere between the extract and MTX due to increase in the leucocyte cells compared with controls. Concluded from these results that methanol extract of A. millefolium has ability enhancement in leucocyte cells in the blood and it has detoxification effect of MTX.

Since time immemorial medicinal plants have been used in healthcare to treat different human disease. The ideals of medicinal plants are highlighted due to the utility of the common-factor approach to engage other health promoters in propagating. One of these medicinal plants is Calotropis procera which is a species of tree in the family Apocynaceae. Calotropis procera is widespread in tropical Africa, including the Indian Ocean islands and the northern parts of South Africa. The latex is toxic and can cause rash, blisters and serious inflammations in sensitive persons and it may lead to blindness. Several side effects may be caused due to ingestion large doses of latex like burning in the throat, irritation of the stomach, nausea, vomiting, diarrhea, tremors, vertigo and convulsions. This study aimed to evaluate burns healing effects and inhibitory concentration IC50 of Calotropis procera latex on cervical cancer cell line, SiHa. Cytotoxicity analysis was performed by MTT assay in addition to determine the burns healing effect of the latex by determining the day requiring to heal the burn skin of albino male mice. The results of burns healing effects declared that the burns required 12 days to heal in comparison with positive (sliver sulfadiazine) and negative control which required 16 and 18 days for healing respectively. Also, the results revealed that the IC50 of latex was 146.8 % in comparison of ambiguous percentage of normal cell line WRL68 with reduction in cancer cell viability ranging from 95.87± 0.20to 52.35 ±3.31 for 6.2 to 400 µg\ml respectively.

Herbal medicinal products can contain whole or partially prepared plant components from plant leaves, bark, stems, flowers and seeds.They are administered orally, inhaled or directly applied in the skin. Ruta chalepensis is a wild herb of the Mediterranean region used by many countries in herbal medicine. The existence of bioactive molecules responsible for their pharmacological properties has been shown by phytochemical screening. Results of kidney protective activity of plant. Showed that: for total cholesterol, the effect was dose dependant (50 and 100 mg\kg) in which the plant decreased it in compared to positive and negative groups (162.1±1.83 and 154.6±1.11 mg\dl) compared to (202.1±1.13 and 167.5±2.96 mg\dl) respectively. For total protein, creatinin and albumin the plant also had the ability to keep it near control groups compared to CCL4group.While the results of interaction groups indicated the ability of plant to provide protection against CCL4 damage. the plant possessed the ability to keep testosterone, progesterone and estrogen hormones level near normal in compared to CCL4 treated group (2.96±0.03, 1.93±0.01 and 3.63±0.04 ng\dl); (11.51±4.12, 9.85±2.18 and 11.78±3.42 ng\ml); (29.07±7.21, 30.11±9.11 and 30.67±8.98 ng\ml) for 50,100 mg\kg and negative control respectively. While for interaction group the results showed the ability of plant to counteract the damaged caused by CCL4 (1.67±0.01, 2.54±0.02); (10.42±2.21, 13.65±4.37); (39.74±10.13, 35.45±9.91) for testosterone, progesterone and estrogen hormones in Ruta chalepensis +CCL4 at dose (50 +0.02%) and (100+0.02%) respectively. All results of histo-architecture for kidney and testis showed the ability of plant to counteract any necrosis and abnormality caused by CCL4.
