The present study has been conducted to evaluate the antialgal activities of
Tinospora cordifolia leaves extracts, these extracts included Terpens, Alkaloids, and
Phenols of that plant against 3 algal isolates: Anabaena circinalis, Scenedsmus
quadricauda and Mougeotia scalaris. The agar well diffusion method was used to
evaluate the inhibitory actions of these extracts with 3 concentrations: 5, 10, and 20
mg/ml. The experiments were conducted and analyzed as factorial experiments with
three replications using a completely Randomized Design, Means were compared
according to L.S.D. values at 5% significant level.
Results showed that A. circinalis was the most sensitive to alkaloid extract and
the diameterinhibitionzone was 40 mm in 20 mg/ml concentration, while this alga
was less sensitive to phenol extract anthe inhibition zone was 17 mm. also the
results showed that alkaloids extract was most active against all algae usedin this
study followed by terpens extracts, while the phenols extracts had lower antialgal
activity.
Background: Enterococcus faecalis is emerging as an important endodontic pathogen, which can persist in the environment for extended periods after treatment and may cause endodontic failure. It is known to produce biofilms, a community of bacteria enclosed within a protective polymeric matrix. This study aimed to establish whether the biofilm formation by Enterococcus faecalis can be inhibited with steralium, co+steralium, and 5% sodium hypochlorite in the root surface environment. Materials and Methods: Extracted human teeth were biomechanically prepared, vertically sectioned, placed in the tissue culture wells exposing the root canal surface to E. faecalis to form a biofilm. At the end of the 3rd and 6th weeks, all groups were treated fo

The study was conducted at research station A, department of field crops, college of agricultural engineering sciences, university of Baghdad during summer 2021 to evaluate the effect of boron and some growth regulators on some growth criteria and yield of soybean crop (cv. shimaa). The experiment was carried out according to split plots by using randomized complete block design with three replications. The main plots included three concentrations of boron (75, 150 and 225) mg.L-1, the sub-plots included three levels of growth regulators, spraying kinetin (100 mg. L-1), spraying ethrel (200 mg.L-1) and spraying kinetin (100 mg.L-1) + spraying ethrel (200 mg.L-1) as

Alkaloids’ continence of Calotropis procera leaves are detected by two biochemical alkaloid reagents. Also GC-MS analysis for leaf alkaloid extract was done that showed the existence of one type of alkaloid compound at retention time12.8min detected as colchicine (C22H25N06( by comparing it with colchicine standard reference (Sigma Aldrich) with M.wt 399g/mol and percentage area 7.1%. Furthermore, identification, separation, and purification

The Ethanolic extracts of different Iraqi indigenous plants which belong to different families showed algicidal activity against Anabaena, Nostoc and Myxosarcina species. Peganum harmala extract was the most potent in controlling the growth of tested Cyanobacterial species
Medicinal plants are a source for a wide variety of natural active compounds and are used for the treatment of diseases throughout the world. Conocarpus erectus L. widely planted all over Iraq and has different secondary metabolites, which has been used in treatment of anemia, cancer, fever and diarrhea. The present study aims to estimate the antibacterial activity of Conocarpus erectus leaves extracts on some microorganisms collected from patients with burn infection. The study began with the collection of Conocarpus erectus leaves in June 2018 from the trees in university of Baghdad. Maceration method was used to prepare aqueous extract, while Soxhelt apparatus was used to prepare methanolic extract. The results of phytochemical test show

Background: Cutaneous leishmaniasis is an endemic protozoal disease in Iraq. Recovery from the disease confers a solid and permanent immunity. Vaccination with a living inoculum of promastigotes isolated from culture reduce the incidence of disease.
Objective: To show the efficacy of different types of antigens for protection of Balb/c mice against cutaneous leishmaniasis.
Methods: Thirty Balb Ic mice were divided in to six groups, groups 1-4 were immunized with different types of antigens (heat killed, freezing-thawing, formalin fixed and ultrasonicated). Received June 2005 Group 5 was treated with freshly harvested viable promastigotes from liquid medium as positive Accepted Nov. 2005 control and group 6 was kept as negative con
Aflatoxin B1 (AFB1) is a mycotoxin produced mainly by fungus Aspergillus flavus in food and feed . It is considered as a carcinogenic toxin for human and animals. The current study was designed for produce antibody (IgG) against aflatoxin B1.It was achieved by immunization of experimental animals (New Zealand White rabbits) with prepared antigen consist of aflatoxin B1-BSA Conjugate (100 and 200 μg ) concentrations, and detection of produced antibody using Ouchterlony double immunodiffusion and ELISA techniques,. Ochterlony and ELISA techniques revealed that, high titer of IgG antibody was obtained by rabbit’s immunize, and the titer of antibody was increased steadily during the immunization schedule. The highest titer of antibody rea
