A comparison of the Effects of Lemon Peel -Silver Nanoparticles Versus Brand Toothpastes and Mouthwashes on Staphylococcus Spp. Isolated From Teeth Caries
...Show More Authors

Thirty one  samples of gum swabs were collected from patients with tooth caries (5-30 years old)  from the College of Science (Biology department )- University of Baghdad- Iraq for the period from October 2018 to December 2018. , The samples were transported, after inoculation in a transport media (nutrient broth), to the laboratory of the College of Science and then cultured on mannitol salt agar and  blood agar). The isolates belonging to Staphylococcus spp. were identified by biochemical tests and Vitek 2 compact system, while the more antibiotic resistant isolates were identified by using Polymerase Chain Reaction(ï´¾PCR)  and sequencing of 16SrRNA . The results showed sharp UV absorption peaks at 330 - 340nm and AFM at 56 nm. Transmission Electron Microscope (TEM) results showed that lemon silver nanoparticles (NPs) are spherical in shape. The results also demonstrated that  the silver NPs have a higher antibacterial activity with a diameter of inhibition zone that reached 16mm as compared with the common three mouthwash and toothpaste brands (Colgate, Crest and Close up) that had inhibition zone values of 5-8mm.

Effects of Coriandrum Sativum on the Spermatogenesis of Rat Testis: Histological and Morphometrical Studies
...Show More Authors

ABSTRACT: BACKGROUND: Coriandrum Sativum is a native of Mediterranean region and is grown in North Africa, central Europe, and Asia as culinary herb and medicament. In addition to the other health-supporting reputation, coriander has hypoglycemic, hypolipidemic, and aphrodisiac effects. OBJECTIVE: To study the effect of Coriandrum Sativum on process of spermatogenesis. MATERIALS AND METHODS: Coriandrum sativum was given daily to mature male rats in a dose of 50mg/ 100g body weight for 14 days. 10% formalin fixed paraffin-embedded tissue sections were performed for histological and morphometrical studies. RESULTS: Histological study showed wider seminiferous tubules & increased spermatocytes population with an increased sperm density

Background: Analysis of human reports and comparison with results of experimental animals indicate that the effects of progesterone on human not analogous to experimental animals fetus, many studies showed that exposure to progesterone during developing of genital tract of human fetus was not teratogenic. Other studies which performed on laboratory animals found association between progesterone administration during gestation and genital malformation. Objectives: to explore the effect of progesterone in 10.2 mg/kg intraperitoneal injection in mice on testis development and anogenital distance. Materials and Methods: ten pregnant mice divided into five mouse control group that injected10. 2mg/kg sesame oil and treated group that injected pro

Effect of Ascorbic Acid on Pathogenic Staphylococcus aureus Growth singly and in Combination with Some Antibiotics
...Show More Authors

 One hundred and fifteen isolates of Staphylococcus aureus were isolated from human infected wound and burn. The resistance of this organism for eight commonly used antibiotics was determined by disc diffusion methods.          The minimum inhibitory concentration MIC was determined for each drug by tube dilution method. Results showed significant variations in the MIC values. It was found that two isolates had high resistance for the eight antibiotics used. Effect of ascorbic acid on bacterial growth was studied singly and in combination with antibiotics. Reductions in MIC value were reported for different antibiotics when tested by growth curve method too.

Serological relatedness among clinical and environmental Acinetobacter baumannii isolates isolated from hospitals in Baghdad
...Show More Authors

During 2011, 1900 clinical specimens (urine, wounds, burns, blood and sputum) and
240 hospital environment specimens were collected from four hospitals in
Baghdad/Medical city including: Baghdad Teaching Hospital, The Martyr Gazi Al-
Hariry Hospital, Welfare Teaching Hospital and The Burn Specialist Hospital. All
specimens were cultured and 128 Acinetobacter baumannii were obtained from
clinical and environmental specimens in a ratio of 6.05% (n=115) and 5.42%
(n=13), respectively. These isolates were identified using microscopic examination,
biochemical tests and Api 20 E system.The slide agglutination technique for rabbit
immune sera and A. baumannii bacteria was used and our data analysis revealed a

Estimating the inhibitory effect of Lactobacillus isolated from vagina against some pathogens of genital infections in group of women.
...Show More Authors

Thirty- five vaginal swab samples were obtained from women vagina.All samples
were subjected to conventional morphological and cultural characteristics, isolates
distributed between Lactobacillus acidophillus(23)and Lactobacillus fermentum (12).
Antibacterial activities were done by well diffusion and blank disk method. The
Lactobacillus was used as aprobiotic treatment against bacteriaisolates from vagina
.The isolated bacteria had strong activity against indicator strains.The results showed
that Lactobacillus which was isolated from vagina by well diffusion method was
effective against pathogenic isolates more than the Lactobacillus isolated by blank
disc method , the highs inhibitory effect of Lactobacillus iso

Correlation between Caries Related Microorganisms in the Dental Plaque and Saliva with Dental Caries Level in the Upper and Lower Jaws in 5-9 Years Old Children in Baghdad City
...Show More Authors

Background: The oral cavity is considered as a complex ecological niche, its complex microbial community is reflected to it. Streptococcus mutans has been implicated as one of the major etiological factor of dental caries. Tooth surfaces colonized with Streptococcus mutans are at a higher risk for developing caries, while lactobacilli are considered as the secondary invaders, not initiators of the carious lesion. The main purpose of this study was to correlate the dental caries (for primary and permanent teeth) in the upper jaw with the streptococcus mutans and lactobacilli count in the dental plaque and saliva, also to correlate the dental caries (for primary and permanent teeth) in the lower jaw with the streptococcus mutans and lactobaci

Occurrence of Point Mutations in gyrA and parC Genes of Ciprofloxacin-Resistant Pseudomonas aeruginosa Isolated from Burn Infections
...Show More Authors

     The spread of antibiotic resistant bacteria is a worldwide problem. Due to the importance of P. aeruginosa as a multidrug resistant bacterium, this study aimed, through molecular techniques, to detect point mutations in chromosomal genes responsible for the quinolones class of antibiotics resistance. A total of 52 isolates from burn infections were identified using specific primers for P. aeruginosa 16S rDNA. Ciprofloxacin minimum inhibitory concentrations (MIC) were estimated using the agar dilution assay. DNA sequences of the quinolone resistance-determining regions of gyrA and parC were determined for detecting the mutations found in these genes and the relations among the i

A Comparison between the Product-Refill and the Equalization Oxygen Pressure Swing Adsorption Processes
...Show More Authors

This work presents a design for a pressure swing adsorption process (PSA) to separate oxygen from air with approximately 95% purity, suitable for different numbers of columns and arrangements. The product refill PSA process was found to perform 33% better (weight of zeolite required or productivity) than the pressure equalization process. The design is based on the adsorption equilibrium of a binary mixture of O2 and N2 for two of the most commonly used adsorbents, 5A & 13X, and extension from a single column approach. Zeolite 13X was found to perform 6% better than zeolite 5A. The most effective variables were determined to be the adsorption step time and the operational pressure. Increasing the adsorption step
