Abstract: The present study aimed to discover the histopathological of the Monosodium glutamate (MSG), and Sodium nitrite (NaNO2), on the embryonic development of the eyes of albino mice Mus musculus. On the fourteenth and eighteenth day of pregnancy, the stage of organogenesis in these animals. A concentration of 9 g/kg of MSG, a concentration of 110 mg/kg of NaNO2, and the interaction between them used. The results of the study showed the presence of pathological changes to the eyes of the fetuses. The eye on the 14th day of pregnancy, when 9 g/kg of MSG used, there were retinal duplication, increased vascularization in the retina, condensation of some nuclei of the inner nuclear layer and ganglion cells, and necrosis in the vicinity of the lens. When treating with NaNO2 110 mg/kg, there was an irregularity in the lens, corneal distortion, hyperplasia of the retinal nerve tissue. When the two materials overlapped, the corneal tissue necrosis, the lens fiber, and the inner plexiform layer were observed. On the 18th day of pregnancy, when treated with MSG 9g/kg, the most significant overall and striking damage was retinal duplication and optic nerve necrosis. When treated with NaNO2 110 mg/kg, the corneal stroma and dissociation were seen in the photoreceptor cells. In the case of their overlapping, extensive necrosis and reduction appeared in all layers of the retina. The study concluded that consuming MSG and NaNO2 more than the permissible limit during pregnancy leads to tissue lesions harmful to the eye.

Abstract: This study accomplished to determine levels of salivary Alpha-Amylase (sAA) in Iraqi children with  positive family history of hypertension, Hypertension was believed to be a risk factor in 18% of all deaths in 2010 (9.4 million globally). This study included one hundred children from primary school aged 6 to 13 years, with a focus in child welfare and family health history, with an emphasis on close relatives' hypertension reputations, with hypertension close relatives record categories identified by 1st and 2nd relatives, after documenting the full details, the burden was assessed for the children's families. The influence of age is confirmed by a correlation study of our own numbers, which shows a positive correlation. The disparity between age and salivary amylase level was important, with age group (12-13) years students having a higher mean salivary amylase level (309.7 U/L) than age group (6-7) years students (270.6 U/L). The gender outcome did not exceed statistical significance, but the gap was not important, which may be due to the limited sample size.

Abstract:  In order to understand the medical effects of heavy metals, the antimicrobial effect of Cd (II) metal ion, Zr (IV) metal ion, Ligand and their complex compounds resulting from their combination, was studied on the growth of gram negative and positive bacteria as well as yeast. It turns out, that all bacterial isolates (Bacillus subtilus, Stapphylococcus aureus and Pseudomonas aeuroginosa, Escherichia coli, Klebsiella pneumonia, Proteus vulgaris, Salmonella typhi, Shigella flexneri and the yeast Candida albicans), have a high resistance of 100% to Colistin (10µg/disc) and Nystatin (10µg/disc), while the Zr (IV) metal is better than Cd metal in its effect on inhibiting the growth of different types of pathogenic bacteria isolated in this study.In the study of minimum inhibition concentration (MIC) of metal Cd (II), Zr (IV) and,  Ligand complexes, on the growth of bacterial isolates, it was also shown that Cd and Ligand 4-bromobenzaldazine (BrA) at the concentration 0.00025g/ml, had an effect of 88 and 100% as the lowest inhibitory concentration for the growth of all bacterial isolates of different species. 

Abstract: Cystic echinococcosis is one of the most prevalence and dangerous zoonotic parasitic disease in the world. Iraq is one of the most countries that affected by this disease. Surgery is usually the most effective therapy and can be used with injection of drugs in hydatid cysts before surgery to kill protoscoleces to avoid anaphylactic shock as a result of spilling of hydatid cyst fluid into peritoneal cavity, as well as this reduce the chance of secondary hydatid cysts production. Therefore, the current study  aimed  to evaluate the effectiveness of Saussurea costus extracts on protoscoleces viability of Echinococcus granulosus, where the protoscoleces of E. granulosus exposed to four different concentrations of Saussurea costus extracts at four different exposure times  including; 15, 30, 45 and 60 min in vitro, The results of ethanolic extract showed highest efficacy at concentration 20,30mg/ml in 45,60min and 40mg/ml at all times. The highest scolicidal effect of  petroleum ether extract was reported at 10 and 15mg/ml during 60min, while 20mg/ml reported similar effect at 45 and 60min. The data of cool aqueous extract showed reduction of protoscoleces viability to 0% at 200 and 250mg/ml in 45 and 60min, respectively, while 300mg/ml showed same reduction of viability at all experiment time periods.The data of hot aqueous extract showed 100% kill rate by using  350mg/ml at 60min and 400mg/ml at 45 and 60, as well as 450mg/ml at all experiment period times. Comparing to the control group. Generally, Saussurea costus extracts have concentration and exposure time-dependent effect on protoscoleces viability.

Abstract: In this study, thirty-six local isolates of rhizobial bacteria were isolated from root nodes of different leguminous plants collected from different areas in Nineveh Governorate/Iraq. The rhizobial colonies were purified and their agronomic and biochemical characteristics were studied. Results of this study showed that the local isolates had the ability to consume different sugars as a carbon source. Also, the antibiotic sensitivity test showed that only one isolate, Rhizobium leguminosarum bv. phaseoli AS12 was resistant to the antibiotic Azithromycin 15 µg/ml, and the isolate Rhizobium leguminosarum bv. phaseoli AS14 showed resistance to the antibiotic Gentamycin 10 µg/ml, and the rest of the isolates showed different rates of resistance and sensitivity for the rest of the antibiotics. The local isolates showed different NaCl tolerance levels up to 8.0 %, while no tolerance was observed for Rhizobium leguminosarum bv. viciae AS11 isolate at any of the studied concentrations. Results of heavy metal salt tolerance study showed that the isolates of Ensifer meliloti AS34 and Rhizobium leguminosarum bv. viciae AS36 were sensitive to ZnSo4 at a concentration of 25 µg/ml, while the tolerability of the other isolates to the studied heavy salts differed at concentrations higher than 25 µg /ml. All the studied isolates showed a positive result in staining with Congo red and Aniline blue dyes. Maximum exopolysaccharide production was 494 mg/Li by Rhizobium leguminosarum bv. viciae AS35. Antimicrobial activity test showed maximum inhibition zone 17 mm by Rhizobium leguminosarum bv. viciae AS36 against Proteus vulgaris.

Abstract: The HbA1c test and the blood glucose test were compared in order to diagnose type 2 diabetes and determine the best cut-off point for the HbA1c test for optimal sensitivity in the population of Mosul city (inside it and some rural areas around it). The test was performed on a group of people between the ages of 40 and 85 who came to our laboratory after being diagnosed with or without type 2 diabetes by specialists in internal medicine and endocrinology. The HbA1c and FBS analysis were carried out between January 2020 and January 2021. And, by using ROC curve, the results for 80 individuals with an average age of 56 years produced a HbA1c test with a value of 6.8 percent, a sensitivity of 94 percent, compared to the result of 126 mg/ml for FBS as a diagnostic criterion , and the optimal cutoff point for HbA1c was reached for 6.86% in diagnosing disease diabetes type 2 was given the highest Yuden index by ROC curve analysis. Conclusion: We recommend that the optimal value of Hb2 with a percentage of 6.86 percent be used as the best test in diagnosing type 2 diabetes and obtaining the best medical and health care for the Mosul population.

Abstract: Rhizobia represents one of the most important types of beneficial soil bacteria, as it contributes to fixing atmospheric nitrogen. In the present study, twenty four isolates of rhizobial bacteria were isolated from root nodules of six leguminous plants. These are Medicago sativa وTrigonella foenum-graecum, Cicer arietinum, Vicia faba, Lens culinaris and Lupinus spp. which planted in four regions of Ninevah province (wire farm house in the Education College / Mosul University , Ba'shiqah town and Sadaa & Bauazh) for the agricultural season 2010-2011. These isolates were put in six groups depending on diagnostic tests and type of plant host (alfalfa , fenugreek, chickpeas, bean , lentils and lupine)  from which the bacteria isolated from their  root nodules. These groups are RhM , RhT , RhC , RhF , RhL and RhLu respectively. RAPD – PCR technique with four random primers were used to draw the genetic Dendrogram in order to demonstrate the relationships among the species of rhizobial bacteria isolated from the root nodules of different host. The results revealed that there are genetic diversity among these species and also diversity still exist among the isolates of the same species but at low level. According to the results of diagnostic tests, RAPD – PCR technique and specificity of rhizobial bacteria to infect their hosts, we can relate the isolates in the suggested groups to their scientific names as follow: Sinorhzobium meliloti (RhM) , Sinorhzobium meliloti (RhT) , Rhizobium legumenosarum bv. cecir (RhC) , Rhizobium legumenosarum bv. vicia (RhF) , Rhizobium legumenosarum bv. lentil (RhL), Rhizobium lupini (RhLu).

Abstract: This study was carried out in the laboratories of the Research Unit of the Department of Biology / College of Education for Pure Sciences / University of Mosul/Iraq. Sinorhizobium meliloti bacteria were isolated from the root nodes of alfalfa plants cultivated in two areas of Nineveh Governorate, which are the wire house in the College of Education / University of Mosul and a farm belonging to Hawi  Alkanesa Mosul/Iraq.  , isolation of four isolates of Sinorhizobium meliloti from the root nodules formed on four species of Medicago sativa (Iraqi, Belgian, Pakistani and American varieties)and giving them the symbols Rh1, Rh2, Rh3 and Rh4. The isolates were diagnosed based on the phenotypic traits, their susceptibility to staining with Gram stain, agricultural characteristics, the biochemical and biological tests.  The results showed that the highest susceptibility of rhizobal isolates to infecting a specific genotype (the plant host) from which they were isolated, which is due to the extent of compatibility between them represented by the success of infection and the formation of root nodules, and its development on the specialized host. All isolates (Rh4, Rh3, Rh2 and Rh1) of  E. meliloti showed the ability to form root nodules on the roots of the seedlings of the four varieties with variation in the efficiency of these isolates ,The isolates (Rh1)  as recorded the highest percentage of infection, which reached to 68%, followed by isolates (Rh2) and reached to 64% which was reflected in the rate of increase in average of the number of nodules / seedlings, which ranged between (2-3.25) and the high protein content of the pollinated seedlings which average ranged between (3.9 - 4.1) mg / gm, and  accompanied by an increase in the rate of the number of vegetative branches therein.

Abstract: This study was conducted with the aim of evaluating the ability of the synergistic effect of nine plant essential oils with antibiotics in removing the antibiotic resistance characteristic of the multiple drug resistance pathogenic bacteria. The disc diffusion method was used for this purpose and the oils were synergized with antibiotics showed resistance by the studied bacteria. The results showed a synergistic effect (ranged between 3 - 40 mm) for different oils with antibiotics according to the type of bacteria, that the most numerous cases of synergism (27 cases) were with P.mirabilis and the highest synergistic inhibition occurred with the same bacteria (40 ml). Pomegranate seed oils, thyme, rosemary and cinnamon were able to synergize with six antibiotics, while eucalyptus, Peppermint, ginger and orange synergized with five, Lavender oil synergized with four antibiotics. We conclude from the results of this study the possibility of combining plant essential oils with antibiotics to remove resistance, which opens the door to finding new ways to treat many diseases caused by multiple drug resistance pathogens.

Abstract: Salmonella typhi is one of the most common causes of typhoid fever in Iraq. The aim of this study was to test the synergistic between different tests for the diagnosis of S. typhi . It was found, there are ability for preparing local Media which can be used instead of Blood agar for diagnosing typhoid fever by using dates, alfalfa and fish extractors. Both fish and dates extractors were used to prepare a local medium as well as alfalfa and fish. The results showed that dates - fish medium are more efficient  than blood agar and alfalfa - fish medium to isolate S. typhi. When contrasting culture results with Widal test data of laboratories , it had shown differences in these results because only (57)% from Widal test was confirmed by culture. When Widal test results were evaluated which is done in different health analysing laboratories in Nineveh Governorate by using Widal test (dilution method) the results showed great differences of results whether result type (positive or negative) or kind of antigens which showed  positive results. Leukocyte count was done as a test to enhance the diagnosis of this microbe, it was clear that there is a relation between typhoid fever and decreasing white blood cell count.

Abstract: Urinary tract infection is the second-largest infection, especially in elderly people, and the increasing use of antibiotics has led to the emergence and development of resistance in isolated and other bacteria in this study Fifty urine samples from elderly patients with urinary tract infections were collected from both sexes in Mosul city. Twenty-six bacterial isolates were isolated and diagnosed by ordinary bacteriological tests. The isolates were related to the species. Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and Proteus mirabilis. After isolation, their resistance to 14 selected antimicrobial agents was tested by the disk diffusion method. The presence of β-lactamases, in general, was detected by acidimetric method, the detection of extended-spectrum β-lactamases(ESBLs) was performed by double disk method, while the detection of AmpC β-lactamases was performed by cefoxitin resistance method. The isolates showed clear resistance         to β-lactam antibiotics ranged (50%--92.3%),and to ciprofloxacin, gentamicin, sulfamethoxazole, streptomycin, rifampin with rates; (53.8%),(57.7%), (61.5%), (80.8%), (88.5%), respectively, while they showed reduced resistance to amikacin (15.4%). β-lactamases in general were detected in (96.1%) of the isolates, while (19.2%) of them gave a positive result for the detection of (ESBLs). AmpC β-lactamases were detected in (69.2%) of the isolates as they showed a clear resistance to cefoxitin which indicates that they are potential producers of these enzymes.

Abstract: In this study, the sensitivity and resistance of six types of bacterial isolates, Escherichia coli, pseudomonas aeruginosa, Staphylococcus aureus, Proteus vulgaris, Proteus mirabilis, and Klebsiella pneumoniae, against 10 antibiotics were tested for 10 antibiotics, Ciprofloxicine (CF) 25 g / ml Amoxicillin (AX) 50 g / ml, Ampicillin (Am) 50 µg / ml, Erythromycin (Ery) 15 µg / ml, Gentamycin ( GN) 25 g / ml, Rifampicin (RA) 50 µg / ml, Streptomycin (Sm) 25 µg / ml, Tetracyline (TE) 15 µg / ml Trimethprim (Tri) 10 µg / ml Nalidixic acid (Nal) 30 µg / ml. The bacterial isolates showed different resistance to most antibiotics. One isolate of each bacterium was selected for subsequent experiments. The aqueous and ethanol extracts of Citrus aurantium L fruit were prepared. The inhibitory effect of the prepared plant extracts on the selected bacteria was investigated by using the Agar diffiuision method and the Turbidity method. The prepared plant extracts showed a clear growth inhibitory activity, which was estimated by measuring the inhibition zone with a millimeter of studied bacteria. The results obtained showed that the value of the growth inhibitory activity increased with increasing the concentration of the extracts. Sub minimum inhibition concentration of plant extracts was used as a curing to remove antibiotic resistance of the bacterial species under study. Varying values ​​for the percentage loss of antibiotic resistance were obtained as a result of the efficacy of the extracts, but some extracts did not show curing efficacy. The results of the curing experiments were supported by the characterization of the plasmid DNA on the agarose gel of the curing isolates. Electrophoresis showed the disappearance of the plasmid DNA bundles from the agarose gel for most of the bacteria under study compared to the non-curing isolates.
