The present study was designed to evaluate some immunological and cytogenetic effects of Micromeria myrtifolia extracts (methanol and hexane) and methotrexate in albino male mice (in vivo). The immunological parameters were total and absolute counts of leucocytes, total serum IgG level and metaphase index of bone marrow and spleen cells, while cytogenetic  evaluations included micronucleus formation in polychromatic erythrocytes of bone marrow and sperm-head abnormalities. Additionally, a chemical

 The present study was carried out to investigate the chemical analysis of Ocimum  sanctum for different active compounds, and prepare methanolic and hexane extracts to determine their antimicrobial activity (in vitro). The cytogenetic effects of (methanolic and hexane extracts) as well as methotrexate (MTX) was evaluated in albino male mice (in vivo). The cytogenetic analyses were extended to include mitotic index and chromosomal aberrations.  The study also tried to investigate the role of O.

Eighty soil and sewage samples were collected from different environmental locations to isolate isoamylase producing Pseudomonas. From these samples, 100 isolates were obtained, among them 40 were identified as Pseudomonas sp. according to the morphological characteristics and biochemical tests. These isolates were screened to examine their ability in isoamylase production. Results showed that all these isolates were producers of isoamylase. An isolate (Pseudomonas sp.
