Some Genetic Changes in Lymphocytes and Bone Marrow Cells Associated with Yasmin Contraceptive Pills, Cafergot and Wild Carrot Seeds Oil in Women and Mice

           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.

Immunomodulatory Effects of Probiotics on Salmonella enterica Serovar Typhimurium Isolated from Diarrheal Children in Albino Male Mice

         This study aimed to determine the frequency of Salmonella Typhimurium and its multi-drug resistance (MDR) status as a diarrheal causative pathogen in children younger than five years old, as well as to investigate the role of four probiotic microorganisms(L.acidophillus,L.casei,S.cerevisiae,S.boulardi) in controlling such infection.For this purpose, 128 stool samples of patients (76 males and 52 females)

Production, Characterization and Genetic Study of Pantoeadispersa Producing Cellulase and pectinase

      Soil samples were collected from fields cultivated with wheat and barley and from spoiled orange, apple fruits and carrot roots to enzyme  isolate bacteria producing lytic. Bacterial isolates were screened for enzymes production on selective media containing carboxymethyl cellulose (CMC) or pectin as a sole source for carbon and energy.

Antimicrobial activity and cytotoxicity of active compounds of Withania somnifera extracts

       In this study Withania somnifera leaves were collected from gardens of Al-Nahrain University. Then the leaves powder was used to get three type of extracts, each type of Withania extracts (water, ethanol and acetone extract) were subjected to chemical analysis to identify the active compounds in each extract which indicated that alkaloids, glycoside, saponins, flavonoids, fixed oil were present in ethanol, acetone and water extracts, while absent of terpene in water extract and protein in acetone extract, Tannins were not found in all extract types.

Osteoblast formation from MesenchymalStem Cells Derived from mouse Bone Marrow in vitro

This study was designed to evaluate osteogenic potential of mesenchymal stem cells (MSCs) isolated from mouse bone marrow in vitro. MSCs were isolated by collecting the thigh bone of 50 male albino mice, both the femur and tibia were collected and cells were flushed from bones and MSCs isolated based on the ability of adherence to plastic surfaces. Reactivity MSCs to CD105 and CD34 were tested by immunocytochemistry.

Production, Characterization and Immobilization of Laccase Enzyme from Bacillus cereus Local Isolate

In this study, fifty five soil samples were collected from different locations in Baghdad city. Many Gram positive and negative bacterial isolates were obtained;of which 39 were identified as Bacillus spp. upon subjecting to morphological and microscopic tests. Laccase enzyme activity was determined by quantitative methods using a syringaldazine as substrate for growth of these isolates. Results indicated that 17 of these isolates were laccase producer with different specific activity ranged between 98-600U/mg  protein.

Study the Effect of Loranthus europaeus Extract on Wound Healing Process

Loranthus europaeus is an important medicinal plant, which contains a lot of bioactive compounds. The dried plant fruits were extracted in 80% methanol by maceration. Chemical detection of crud plant extracts was performed. The total flavonoids were isolated, subjected to thin layer chromatography (TLC) using different mobile systems. The purified material was augmented by using high performance liquid

Molecular Detection of Cytomegalovirus (CMV) Isolated from Repeated Miscarriage Women and its Relation to TLR2 and ILT2 Receptors

      This study was designed to determine a molecular status of Toll like Receptor 2 in repeated miscarriage women with cytomegalovirus. One hundred blood samples were collected from repeated miscarriage women with cytomegalovirus from infertility clinic of Kamal Al –Sammaraee hospital and (50) samples from normal subjects served as control for comparison and divided into two age groups:( 20-30) and (31-40) years old.
