           This study was undertaken to figure out the effects of contraceptives pills "Yasmin", fungal alkaloids "Cafergot" and wild carrot seed oil on apoptosis, DNA damage (using comet assay), cytogenetic analysis (using micronucleus assay) in blood lymphocytes of mice as well as on  pregnancy rate of female mice. The oral effects of contraceptive pills (Yasmin) on apoptosis, DNA damage, cytogenetic analysis and aromatase activity of women blood lymphocytes were also investigated.

    The ten bacterial isolates used in this study have the ability to utilizecrude oil and aromatic compounds. They were isolated in the previousstudy and considered as a novel group of aromatic hydrocarbon degradingextreme thermophillic bacteria. These isolates were screened for theirability to produce biosurfactant depending on the emulsification index(E24%), surface tension measurement (mN/m) and emulsification activity(E.A) using crude oil as a carbon source.

   Stem cells are relatively unspecialized cells that have the ability to renew themselves and produce a variety of specialized cells after division without limit, as long as animal is still alive. These criteria were directed to produce many types of differentiated cells to repair damage in the body (Watt , 2011). It is the original cell of an organism that has the ability to develop into many different types of cells in the body.
