The ligand was prepared by fusing sulfamethoxazole and dimedone at (170) ?C for half hour. The prepared ligand was characterized by FTIR,UV - Vis spectroscopy, H1,C3 - NMR spectra, mass spectra, molar conductivity measurement and melting point. The molecular structure for the ligand [H2L] which was proposed as drawn in the figure below : - Ligand [H2L]The complexes prepared using reflux in ethanol as solvent were two types namely : - 1 - Complexes of (1 : 1) mole ratio formula [M(H2L)(H2O)2]Cl22 - Complexes of (1 : 1 : 1) mole ratio formula [M(H2L)(HA)] in the presence of KOH as a base, Where : - M(II) = (Co ,Ni ,Cu) HA= 3 - amino phenol. Spectroscopic methods (FT - IR, UV - Vis spectroscopy) along with (A.A), chloride content and melting point were carried out in addition to molar conductance were done for the characterization of all complexes.The proposed tetrahedral geometry around the metal ions studied were concluded from these measurements. [M(H2L)(H2O)2]Cl2 [M(H2L)(HA)]Molar ratio method were used to determine M to L ratio at maximum wave length (?max=455nm ).The ratio were (1 : 1) mole for both complexes (1) and (4). Bentonite clay was used as adsorbent surface to gather with complexes (1) and (4). The adsorption time investigated was between (15 - 120) min at (25)°C as constant concentration for complexes being (70) mg/L for complex (1) and (50) mg/L for Complex (4) and mesh 75))?m. The results revered that the time needed to reach concentration equilibrium in the were 60 to 75 min for complex (1) and (4). during studying isotherm adsorption for the two complexes on bentonite surface, the results revealed that the trend of the adsorption isotherm was (L1) type according to Giles classification , which means that the adsorbent distributed horizontally on the bentonite surface to from a single adsorption layer type langmire.The adsorption phenomenon was studied at different temperatures (10, 25, 37.5, and 50) oC. The results of the adsorption for both complexes on bentonite surface were showed an increase with increasing temperature (endothermic process). Thermodynamic functions (?Ho, ?Go, and ?So) were calculated and the results were discussed. Generally, the increase in the pH of solution was showed an increase in quantity of both complexes that adsorbed on bentonite clay surface at a certain temperature. The study proved that an increase of adsorbent weight may be enhanced the adsorption process of both complexes. Moreover, the particle size of clay surfaces has an influence on the adsorption process showing an increase in adsorption quantity as the particle size decreased.

المستخلص: ترتبط بعض الامراض النفسية مثل مرض الاكتئاب الشديد والفصام بتغيرات مناعية حتى ولو كان الشخص سليم من الناحية الجسمية. على الرغم من ان هذين المرضين لايعتبران حاليا من الامراض المناعية الاساسية لكن توجد ادلة تقترح كون الالتهاب يلعب دورا في عملية الاصابة بالاك | Psychiatric illnesses, particularly major depressive disorder (MDD) and schizophrenia, are associated with inflammatory processes even in individuals who are otherwise physically healthy. While it is unlikely that MDD and schizophrenia are a primary inflammatory disorder, evidence suggesting that inflammation plays a subtle role in the pathophysiology of MDD and schizophrenia has been obtained. Several studies have shown that proinflammatory markers have increased in these disorders. However, these studies have included patients with obvious inflammation, i.e., patients with C - reactive protein >6 mg/L. A comprehensive study concluding that these conditions are inflammatory disorders and inflammation is due only to these two disorders have not been performed. In the present study, the inflammatory natures of MDD and schizophrenia were investigated. To achieve this goal, serum levels of the interleukins - 6 (IL - 6) and interleukins - 18 (IL - 18), tumor necrosis factor alpha (TNF?), and soluble interleukin - 2 receptor (sIL - 2R) in MDD and schizophrenia were obtained and compared with those of the control group. The total serum and ionized levels of calcium (Ca) and magnesium (Mg) in the studied groups were then measured.Significant increases (p < 0.05) in the serum levels of IL - 6, IL - 18, TNF?, and sIL - 2R in the MDD and schizophrenic groups were observed in comparison with those of the control group. In general, the schizophrenic group showed higher levels of inflammatory markers than the MDD and control groups. These results indicate a clear inflammatory state in both disorders. The schizophrenic patients exhibited significant changes in the ratios of T. Ca/Mg and I. Ca/Mg in comparison with those of the healthy and MDD patients; this finding reveals that T. Ca/Mg and I. Ca/Mg ratios are better indicators of cation state than serum cation levels alone.Basing on the results of the present study, we concluded that the immunological responses of the MDD and schizophrenia are significantly stimulated. These conditions may be considered inflammatory disorders because of increased pro - and inflammatory factors in both disorders.Anti - inflammatory drugs may be potentially used as an adjuvant aid in treating schizophrenia and MDD. Future studies may involve investigating other proinflammatory markers and following up results of treated patients that utilized and did not utilize anti - inflammatory drugs.

المستخلص: تم تصميم الدراسة الحالية للتخلص من عقاري الباراسيتامول والبروكائين باستخدام الاشعة الفوق بنفسجية وبوجود اوكسيد الزنك كعامل مساعد، حيث سلطت الدراسه الضوء على اهمية كل من الضوء والعامل المساعد كعوامل اساسيه في التفكك الضوئي المحفز لكلا الدوائين.تضمنت الدرا | The current study is designed to treat the paracetamol and procaine by using UV light and ZnO as catalyst. This study explains the importance of the UV light and catalyst as a basic factors in the photocatalytic degradation for both paracetamol and procaine drugs. The study includes the measure of the rate of photocatalytic oxidation by measuring the absorbance of samples of aqueous solution for both drugs which is treated by UV light and ZnO. These absorbance are compared with the initial drug's absorbance. Some parameters which are effected on the rate of photocatalytic oxidation are studied in present research such as the amount of catalyst, initial concentration for the drug's solution, pH and the temperature for the drug's solution. The results show that the photocatalytic oxidation reaction for the paracetamol and procaine obey pseudo - first order according to the Langmuir - Hinshelwood relationship, and also it is found that the photoctalytic oxidation rate fits positively with the increase of the catalyst weight until the weights of ZnO equal to 0.025 g and 0.1 g are considered the optimum weights for paracetamol and procaine respectively where the best photocatalytic degradation is happened. So after these values, the photocatalytic degradation rate is decrease or stablized with the increase of the catalyst weight. In addition, the initial concentration increase for both drugs leads to reduce degradation rate. Also this study is found the increase of pH of reaction solution for both drugs has a positive effect represented by increasing the degradation rate until the pH 8 and 4 are the best acidic function of the paracetamol and procaine respectively. Regarding the change of the temperature has a little effect on the rate of photocatalytic degradation and it was noticed that the reaction rate increases with the increase of temperature. Activation energy is calculated according to the Arrhenius plot of lnK vs. 1/T, the slop of linear plot is equal to ( - Ea/R). Activation energy was found equal to 7.96 KJ. mol - 1 for paracetamol and 8.71 KJ. mol - 1 for procaine. The thermodynamic functions are calculated in current study for each drug and the results for paracetamol are as following : ?G = 63.61 ± 2.85 KJ.mol - 1?H = 5.40 ± 0.13 KJ.mol - 1?S = - 0.189 KJ.K - 1.mol - 1And the results of procaine are as following : ?G = 63.43 ± 2.81 KJ.mol - 1 ?H = 6.15 ± 0.13 KJ.mol - 1?S = - 0.186 KJ.K - 1.mol - 1The results of the suggested mechanism of degradation are shown that the final products for degradation are CO2, H2O and mineral acids.

دراسة الخواص الميكانيكية لخلائط المطاط الطبيعي باستخدام انواع مختلفة من البوليمرات والمالئات Study of Mechanical Properties For Natural Rubber Blends Using Different Types of Polymers And Fillers

المستخلص: تم تحضير مركبات نانو مغناطيسية جديدة باستخدام الكوليستيرول والسلفادايزين مع اوكسيد الحديد المغناطيسي. حضرت هذه المركبات باستعمال طريقة الترسيب المشترك لاوكسيدي الحديد الثنائي والثلاثي ومن ثم ربطه بالحامض بطريقة فوق الاشباع. تم تشخيص المركبات المحضرة بالطر | Two new magnetic nanoparticles (MNPs) were prepared using magnetic iron oxides with cholesterol and sulfadiazine. These compounds were prepared by iron oxide (II and III) co - precipitation, and then the prepared MNP were incubated with cholesterol and sulfadiazine. The synthesized compounds were identified using multiple techniques, including transmission electron microscopy, scanning electron microscopy, diffractive light scattering, and thermogravimetric analysis. Results demonstrated the formation of new magnetic nanoparticles, namely, MNP@Cholesterol and MNP@Sulfadiazine. The interaction between the prepared MNPs and xanthine oxidase (XO) was evaluated as a potential method for the inhibition of the enzymatic activity. The inhibition of XO is an important issue to reduce the formation of uric acid, which is responsible for gout and kidney stone formation. Another potential application is the extraction of the XO enzyme from biological fluids, such as blood, or the immobilization of XO on the surfaces of MNPs as a new application of these insoluble particles.The interaction studies involved the incubation of XO solution with the suspension of prepared MNPs using XO solutions with different concentration and fixed MNP mass. The adsorption studies of XO on MNPs showed that the prepared MNPS can extract suitable amounts of XO from a solution. Slight differences in the XO quantities adsorbed on different MNPs were found. Adsorption isotherms followed the Sips equation, indicating slight heterogeneity in the adsorption active forces on MNPs. Circular dichroism study of the XO adsorption on the prepared MNPs showed significant changes in the secondary structures, namely, reduction of the ? - helix structure. Furthermore, fluorospectrophotometric studies showed changes in the tertiary structure of the XO caused by the interaction with the active sites of the prepared MNPs. The study of the inhibition of XO activity by the prepared MNPs showed mixed inhibition as a result of the changes in the original XO enzyme after interaction with the surfaces. Magnetic Fe3O4 showed the highest inhibition activity, followed by MNP@Sulfadiazine and MNP@Choleterol - XO.

تحضير وتشخيص ليكاندات ازو جديدة غير متجانسة الحلقة مشتقة من 5,4 - ثنائي فنيل اميدازول ومعقداتها مع بعض الايونات الفلزية Synthesis And Characterization of New Heterocyclic Ligands Based On 4,5 - Diphenyl Imidazole And Their Complexes With Some of Metal Ions

المستخلص: تضمن العمل تحضير ليكاندين جديدين من ليكاندات الازو العضويه غير المتجانسه المشتقة من البنزامبدازول الاول هو اليكاند 2'] - 2 - (بنزايميدازوليل) ازو [ - 6,4 - ثنائي كلورو فينول Benzimidazolyl) Azo] - 4,6 - dichloro phenol (BIADClP)) 2 - [2' - والليكاند الثا | This study deals with the preparation of two new ligands from the heterogeneous organic azo ligands drived from Benzimidazol.The first) 2 - [6 - Benzimidazolyl) Azo] - 2,4 - dichloro phenol (BIADClP). The second is 2 - [6 - (benzimidazolylazo)] - 2,4 - dibromo phenol(BIADBrP).The heterogeneous chain in both ligands includes two nitrogen atoms. These two ligands have been identification by the proton nuclear magnetic resonance spectra (1H - NNMR) ,the mass spectrum, infrared, visibale ultraviolet as well as the analysis of the micro - elements (C.H.N).And two new series of the solid canine complexes for these ligands. The first series includes six solid complexes of the ligand (BIADClP) with the metallic ions Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Hg(II). The second series includes the preparation of six solid complexes of the ligand (BIADBrP) with the metallic ions mentioned above. The effect of the solvent and the complexes stsbility have been studied on the prepared ligands with the passage of time starting from the moment of the metallic ion solution reaction with the ligand solution and up to 170 minutes. Also, the stability constants for these complexes have been calculated spectrally by visbale - ultraviolet spectra.All results show that these complexes have high stability. The infrared spectra of the prepared complexes have been studied and when compared with the free ligand spedtra give obvious changes as these spectra show new bands not already found in the spectra of both ligands and this is due to the occurance of the correlation between the metallic ions under study with the donar atoms [the nitrogen atom azo group near the heterogeneous chain (N3) and nitrogen atom benzimidazole molecule (N3) , the oxygen atom of hydroxyl group in the heterogenous chain ] in the ligand molecule whereas the other band suffered from obvious changes in shape, intensity and location and this is a proof on the occurance of consistency process between the metallic ions under study and the tow ligands. Atomic absorption spectrometer is used for assigning percentages of the metallic ions in the prepared complexes as well as the analysis of micro - elements (C.H.N). These results indicate the great consistency between the percentages theoretically calculated and practically gained. The magnetic sensitivity indicated that Ni(II) - complex and Cu(II) - complex for both ligands have baramagnatic characteristics whereas the Co(III) - complex, Zn(II) - complex, Cd(II) - complex, Hg(II) complex have adia magnetic characteristics. Also , the study deals with the molar conductivity of the canine complexes dissolved in DMF nad ethanol in a concentration (1×10 - 3) molar and in lap temperature. The results show that the complexes of Ni(II) , Cu(II), Zn(II), Cd(II), Hg(II) do not have ionic characteristics and they are solution of non - electrolytes nature whereas the complexes of Co(III) and for both prepared ligands (BIADClP) and (BIADBrP) have ionic characteristics of the electrolytes nature of type (1 : 1) whereas other remaining complexes do not have any ionic characteristics. Throughout the results that have been reached at, certain structural forms for the canine complexes have been suggested.It has been indicated that the azo Benzimidazol ligands under study behave as tridentate ligands where the consistency happens through the N atom benzimidazole chain (N3) and N azo group far from the heterogeneous chain (N3) oxygen hydroxyl group of the homogeneous chain which leads to forming canine hexagonal complexes having octahydral as steric form.The hybridization of these complexes is d2sp3 concerning Co(III) - complexes of the ligands (BIADClP) and (BIADBrP) whereas the other complexes have the hybridization sp3d2 with the tow prepared ligands under syudy. Moreover, the study deals with the biological activity of these ligands and metallic complexes in the growth of four types of bacterial spores (germs) by using the solvent DMSO and deployment technology as anti - bacterial such as Staphylococcus aureuse and Staph.lentus representative for Gram positive bacteria and enterobacte and Escherichia coli representative for Gram negative bacteria. It is found that ligands and there complexes have different effect as antidepressants in the inhibition and the growth of bacteria under study wheras the ligand (BIADClP) gave the ability in inhibition of the growth of bacteria more than the ligand (BIADBrO) this is due to the change of substituted group on the homogeneous chain and their different in both ligands which led to the emergence of such difference in the inhibition and growth of bacteria.

The concentrations that obeyed Beer - Lambert Law of the complexes were determined from calibration curves , Mole Ratio Method indicate a ratio (1 : 2) (Metal : ligand) for the complexes of (DPEPI) and (DPDED) while other complexes with other ligands show a ratio (1 : 1) (Metal : ligand).Satiability Constants of the complexes were calculated and found that the Stability constants of complexes of the first ligand (DPEPI) were ( 2.955×10 12) >(2.294× 1011 ) <(1.121×10 12 ) < (1.108 ×1011 ) varied in the arrangement as Co(II)< Ni(II) < Cu(II)> Zn(II) which agree with Irving - Williams Series. This arrangement was applied on the complexes of the other ligands. The Conductivity measurements of complexes showed non ionic character. Apparently the magnetic susceptibility values agree with their values of the octahedral high spin complexes for Co(II)) while the complexes of Zn(II), Cd(II), and Hg(II) were diamagnetic. IR Spectra of complexes showed obvious changes of the frequencies of ? (N=N) of azo group and ?(C=N) of heterocyclic imidazole ring as result of coordination with metal ions, While the frequencies of ?(C=N) of azomethine group did not show any significant change for complexes comparing to the ligands spectra ,New bands were appeared in the region (400 - 500) cm - 1 in the spectra of complexes that due to frequencies of ?(M - N) because of coordination process.

The two wavelength of maximum absorption for the two reagents were found (422nm) and (416nm) respectively in ethanol and for the complexes formed between these ions with these reagents were found at (476, 492, 504nm) and (455, 458, 496nm) for cobalt(II) , nickel(II) and copper(II) respectively in aqueous medium.It has been prepared after fixing the optimum condition of concentration and acidity function, through the study of UV - Vis spectrum for reacting of metal solution and two reagents solution. For wide range of pH (5 - 11) and concentration which obey to Beer - Lambert Law.The structures were determine according to the mole ratio method and continuous variation method which is obtained from the spectroscopic studies of the complex solutions. The ratios of (metal : reagent) are equal to (1 : 2) for all the complexes ions.The stability of complexes in the solutions was also studied at the optimum conditions.Diagnosis the solid prepared complexes by UV - Vis spectrum in ethanol solution showed high chromic shift from as compared with free reagents in visible region to all the complexes prepared.Micro elemental analysis for all the complexes were prepared and the percentage of Co(II) and Cu(II) were determined , using flame atomic absorption spectroscopy, it was noticed a great accord between theoretical and particle ratio.The infrared spectrum of chelating complexes also studied and it's compared with the two reagents spectrum. They give notice change with free two reagents spectrum. These showed new bands that were not found original in two reagents spectra but other bands have been changed in shape, in trinity and location. This may indicate that a coordination between the metal ions and the two reagents prepared.The Conductivity measurements for solutions at (1×10 - 3M) in ethanol solution have shown non - ionic character for all chelate complexes.From the above observations, it's suggested stereo shapes for complexes, that show the two reagents (DPIDBSA) and (MBDPI) behave as bidentit reagent, we can conclude that the proposed geometrical structure of all chelate complexes are octahedral.The study also included using spectrum method for determination stability constant of complexes in the thermal rang (25 - 45C?) for complexes with reagent (DPIDBSA) while the thermal rang was (10 - 30 C?) for complexes with reagent (MBDPI), and calculating ?G , ?H and ?S for complexes.The bacterial activity of the ligand and it's complexes were studied toward two type of bacteria : 1 - Pseudomonas. aurginosa 2 - StaphylloCoccus. aureusThe complex of Ni(II) with reagent (DPIDBSA) and the complexes of Co(II), Ni(II) and Cu(II) with reagent (MBDPI) and metal ions solution showed high bacterial activity on Pseudomonas. aurginosa while the solution of two reagents and all chelate complexes prepared also the aqueous solution of metal ions don't showed any activity toward the two type of bacteria (StaphylloCoccus. aureus) (G+ve).

Its identification was done by UV - Vis spectrophotometer, IR and C. H. N. Depending on the results, we found the correspondence between the theoretical calculation and the experimental ones with a way to suggest the final structures of the prepared reagents. The purity of these reagents was tested through thin layer chromatography.The prepared reagents are : 1. 2[(4 - Methyl phenyl )azo] - 4 - Methyl phenol (MePAMP)2. 2[(4 - Chloro phenyl )azo] - 4 - Methyl phenol (CPAMP)3. 2[(4 - Methoxy phenyl )azo] - 4 - Methyl phenol (OMePAMP)4. 2[(4 - Nitro phenyl )azo] - 4 - Methyl phenol (NPAMP)The second part deals with the study of chromatographic behavior of organic prepared reagents dissolved in ethanol according to gas chromatography on stationary liquid phases as capillary columns with different polarities as zebron (FFAT) which is characterized with high polarity, silica fused (BP10) with a medium polarity and poly phenyl siloxine (OV - 5) that appears with low polarity.Gas chromatography was equipped with a flame ionization detector (FID) and the nitrogen as carrier gas with flow rate 30cm3min - 1 at different column temperatures ranged 100C increments depending on columns maximum operation temperature, column inlet temperature and detector temperature were higher than the separation column (25,50) 0C respectively.This investigation attempts to find the optimum conditions for the sequential separation were defined for the azo compounds of all capillary columns such as injection, applied pressure inlet of column, gas flow rate as well as the conditions of the efficient separation.The order of elution and resolution of compounds on various stationary liquid phases were normal chromatographic behavior which is decrease in specific retention volumes with increase of column temperature through the relationship between logarithm of specific retention volume for the studied compounds against reciprocal of absolute column temperature which is observed generally linear relation for all compounds on different liquid phases by using (Clausius - Clapeyron) , then calculate the thermodynamic parameters ?H0 , ?S0 and ?G from the slope and intercept respectively the negative values of partial molar enthalpy ?H0 of solutions indicate to highest interaction between liquid phases and separated compounds. The results show that the zebron (FFAT) consider the high negative value of ?H and the reaction was exothermic, on other hand the highest negative value of ?s means less random of solutes on some liquid phase , so it was more selective towards to prepared azo derivatives of p - cresol. Also calculated separation factor (RS),number of theoretical plate (N), equivalent highest of one theoretical plate (HETP) respectively for mixture of studied compounds on various liquid phases.The precision and accuracy of the prepared organic reagent (MePAMP) from 0.06% to 1.44% for (CPAMP) from 0.91% to 1.5%, (OMePAMP) from 0.03% to 1.42% and finally for (NPAMP) from 0.06% to 1.6%

فحص عوامل عنق الرحم باستخدام فحصي اختراق النطف واتصال النطف بمخاط عنق الرحم للازواج العقيمين Examination The Cervical Factors By Using Sperm Penetration Test And Sperm Cervical Mucus Contact Test In Infertile Couples

المستخلص: The present study was conducted in Infertility unit / Babylon Hospital of Gynecology and Children in a period 21/1/2013 to 15/1/2014. The study involved communiqués tests for males and females complaining from unexplained infertility , in which seminal fluid analysis were normospermia. The study include 45 seminal fluid specimens used in connecting test (SCMCT) and penetrating test (SCMPT) with the specimens of cervical mucus of their wives. Cervical mucus aspirating in day 12 - 14 of menstrual cycle. The study aimed to evaluate the husband's sperm activity and concentration in vitro with cervical mucus. Seminal fluid analysis were achieved and then semen specimens used to performed two in vitro tests : SCMCT and SCMPT. sperm parameters ( sperm concentration and sperm motility grade a, b, c, and d) were evaluated in each mentioned test and compared the results with the values of sperm parameters in seminal fluid analysis (control). The statistic results showed 60% of the study specimens of SCMCT was negative and 40% positive, while in percentage of positive results was 33% and 67% negative in penetrating test. The results revealed a significant (p<0.001) decrease of sperm concentration and grade a and b sperm motility, a significant (p < 0.001) increase of sperm motility grade c and immotile sperm grade d in connecting test with cervical mucus compared to control. The results of penetrating test showed significant (P< 0.001) decrease of sperm concentration in the brim, medium and distal region of cervical decrease (p<0.001) of sperm concentration in both medium and distal region compared to brim region, and a significant (p < 0. 001) decrease in distal region compared to medium region ; A significant (P < 0.001) decrease of grade a + b motility percent in all three regions of cervical mucus area compared to control, while no significant differences (P > 0. 05) between brim, medium and distal region of cervical area ; Only grade C sperm motility in distal region showed a significant decrease (P < 0. 001) compared to control and both brim and medium regions. The results revealed significant increase of grade d (P<0.001) in brim and medium region (P < 0.01) compared to control, while there was a significant decrease (P< 0. 001) in distal region compared to control, brim and medium regions. The correlation (r) study of sperm concentration and sperm motility ( grade : a + b, c and d) with age and infertility period in SCMCT showed non significant (P > 0. 05) correlation, except the correlation between a + b grade sperm motility and age it was noticed a significant negative correlation (P < 0. 05) and positive correlation(p> 0.05) between grade c sperm motility and age. The study of linear correlation of sperm parameters in penetrating test showed a significant(P<0.05) negative correlation between grade a+b sperm motility and age in brim and medium region of cervical mucus area. Except this, there are no significant correlation (P>0.05) between sperm concentration and sperm motility for all grades (a + b, c and d) with age and infertility period in both brim and medium regions It was concluded that both test : SCMCT and SCMPT were necessary to diagnosis the causes of infertility when there were normal finding of both seminal fluid analysis and female criteria. mucus area compared to sperm concentration in control, also a significant

المستخلص: اجريت هذه الدراسة في البيت الحيواني التابع لقسم علوم الحياة / كلية التربية / جامعة القادسية للمدة من 1/9/2013 ولغاية 1/9/2014، للتحري عن انواع طفيلي الاكريات المتطفلة على الدجاج المصاب طبيعيا وعزل الطفيلي من الحالات المصابة الواردة الى المسستشفى البيطري | The study conducted in The animal house of the Biology department, College of Education, University of Al - Qadisiyah during the period from 1/9/2013 to 1/9/2014. The study diagnosed the species of Eimeria parasites in naturally infected chickens in poultry farms. Eimeria oocysts was isolated from the infected chickens feaces in Veterinary hospital and Veterinary clinics.Then, the cases diagnosed initially in the laboratory by direct examining stool smears and the positive cases were recorded.Through this study, oocysts were isolated, and two species of Eimeria parasites were diagnosed (E.tenella and E.maxima) by using the technique of Conventional Polymerase Chain Reaction technique.There are 186 cases of infected chicken which examined, and the results showed that (186 out of 315)stool Samples(59%), include infected with two species of Eimeria parasites E.tenella was in (135 out of 186, 72.5%) while the species E.maxima was in(51 out of 186, 27.4%). The experimental study was conducting two experiments were done.The first experiment, depend on the experimental infection of E.tenella species which was used for two types of chicken, (Ross type which is foreign, and local breed).The second experiment, includes experimental infection with the species E.maxima also in two types of chickens that mention above. Symptoms and clinical signs of the first experiment on foreign chickens included were recorded it is noticed that infected the chickens with E.tenella have was dull, unorganized feather and loss of appetite in addition to bloody diahrreha, loss weight, emaciated and isolated. The Gross Lesions include congestion of cecum and an increase in their sizes while inside the cecum, many ulcerated lesions were noticed, filling cecum with mucus and blood, liver was congested and enlarged. Microscopicale examination recorded congestion was full with blood cells and necrotic tissues cecum and falling of cells in the cecum lumen. Many different stages of the parasites were noticed as schizonts, merozoites, gametes and oocysts Hematological parameters showed high significant decrease (p?0.05) in Hb (0.38±5.94 mg / 100ml) in the fourth week of infection, PCV (0.68±18.47%) in the fifth week and RBC was (1.58±0.02x106) in the fourth week. Also, the infection led to significant increase difference of WBC (30.19±0.95x103) in the seventh week of infection in comparison of uninfected chickens of the control sample. The biochemical parameters of blood serum showed that significant decrease (p?0.05) in glucose concentration (156.98±1.75mg / 100ml in the fourth week of infection), cholesterol concentration and total protein concentration (62.11±4.40, 1.92±0.92 mg / 100ml respectively in the fifth week of infection).Also, Uric acid increased significantly (p?0.05) to reach(10.19±0.52mg / 100ml) in the fourth week of infection in comparison of uninfected chickens of the control group. Average weight was showed the significant decrease (p?0.05) of the chickens quantity (368.88±3.01gr in the fourth week of the infection), and an increase the percentage of mortality(23.33±0.23% in the fifth week of infection), addition to the decrease of consuming food by bird (282.8±2.19gr in the fifth week of the infection) in comparison of uninfected chickens of the control group. While the results of local breed chickens in the first experiment were less severity than that with the foreign type (Ross) but the colour of the stool was brown mixed with blood. The Gross Lesions showed pathological changes in the cecum as congestion and bleeding. Moreover, ulcers areas were smaller and less in number in comparison with the infected foreign chickens by the same parasite. The microscopic pathological changes of E.tenella in the cecum showed hyperplasia in goblet cells and congestion of blood capillaries with less number of stages of the parasite in comparison with the foreign chickens. The hematological parameters showed significant decrease (p?0.05) in Hb concentration and percentage of PCV (7.13±0.31mg/100ml, 21.26±1.82% respectively in the fifth week of infection), while the RBC count was (2.05±0.12 x 106 in the fourth week of infection and significant increased (p?0.05) in WBC count was (30.63±0.38 x 106 the sixth week of infection) in comparison with the chickens of the control group. The biochemical parameters of blood serum showed the significant decrease (p?0.05) in glucose concentration (169.60±2.16mg/100ml in the fifth week of infection), cholesterol concentration and total protein concentration (70.89±2.01, 2.25±0.39mg/100ml respectively in the fourth week of infection). Uric acid increased significantly (p?0.05) to reach (7.62±0.90mg/100ml) in the fifth week of infection in comparison with the control group. Average of the weight was significant decrease (p?0.05) (190.28±3.81gm), high increase in the average of mortality (10±0.20%), and high decrease in the consuming food average (413.4±3.91gr) in the fourth week of infection in comparison with the uninfected control group. The second experiment of the foreign chicken which infected experimentally by E.maxima showed asymptoms and clinical signs were nearly similar in the foreign chickens that infected with E.tenella, but mild in severity is average. The symptoms include fatigue, fallen wings, loss of appetite, mucus diarhea mixed with blood. The Gross Lesions showed severe changes in the infected part of intestine as congestion and filling of intestine with mucous secretion of bad odour. While the microscopic pathological changes showed the tissues section of intestine were damaged, necrosis of intestine villi due to the large number of different stages of the parasite with hyperplasia of goblet cells. The hematological parameters showed significanty decrease (p?0.05) in Hb concentration, percentage of PCV and RBC count (7.55±0.61mg/100ml, 23.62±0.81% and 2.08±0.10x106 in the fourth week of infection) and significant increased (p?0.05)in WBC count (31.26±0.63x106 in the seventh week of infection) in comparison with the uninfection control group. The biochemical parameters of blood serum showed that there was the significant decrease (p?0.05) in glucose concentration (164.86±2.11 mg /100ml in the fifth week of infection), cholestrol concentration and total protein (77.14± 3.38, 2.24±0.36 mg/100ml) and significant increased (p?0.05) in Uric acid concentration (8.20±0.79mg/100ml) in the fourth week of infection in comparison to the control group. The results of productive characteristics refered to significant decrease(p?0.05) in the weight of chickens (479.28±0.23gr) and significant increase (p?0.05) in mortality (10±0.11%) during the fifth week of infection. Also, there was significant decrease (p?0.05) in the consumed food by birds (368.5±2.10gr) during the fourth week of infection in comparison to the chicken of the control group. While the results of local breed chicken in the second experiment, the symptoms and clinical signs showed no sign of disease, and the chickens were active in spite of presence of infection and the releasing of Oocysts. The Gross Lesions showed the inflammation and congestion, onlargment of the infected part of small intestine, little mucous and liquid inside the lumen.As far as microscopic changes are concerned, the tissue examination showed some necrosis and damage of the villi ends and an increase in the size of the goblet cells. Hematological parameters showed to the significant decrease (p?0.05) in Hb concentration and percentage of PCV (7.86±0.45 mg/100ml, 23.60±0.53% respectively during the fifth week of infection), RBC count (2.10±0.13 x 106 in the fourth week of infection) and significant increased (p?0.05) in WBC count (32.98±0.58 x 106 during the sixth week of infection) in comparison with the control group. The biochemical parameters of blood serum showed that there was the significant decrease (p?0.05)in glucose concentration and cholestrol concentration (170.60 ±2.01, 79.70±2.69 mg/100ml respectively in the fourth week of infection), total protein concentration (2.42±0.31mg/100ml in the fifth week of infection) and significant increased (p?0.05) in Uric acid concentration (6.52±0.82mg/100ml in the fourth week of infection) in comparison to the uninfection control group. Average of the weight referred to significant decrease (p?0.05) of chickens (213.16±3.12 gr) and consuming food (481±3.21 gr) during the fourth week of infection.While there were no differnces in the percentage of mortality comparison with the uninfected chicken of the control group. Also, the results of the number of released oocysts showed significant increase (p?0.05)in number of released oocysts with stool by infected foreign ckicken(Ross) in comparison with the local breed chicken which infected by the same parasite.Also, the number of the dropped oocysts of E.tenella were higher than that of E.maxima.

دراسة بعض جوانب الاداء الحياتي لبعض الحشرات ذات الاهمية الجنائية في مدينة الديوانية A Study of Some Biological Aspects of Forensically Important Insects In Al - Diwaniya City

المستخلص: The present study was aimed to identify the most forensically important insects species in addition to their distribution and abundance in the Al - Diwaniya province, also the succession pattern on carrion in urban and rural areas in different seasons was studied. The present study included some experiments on the effect of the quality and quantity of food on the development of some blow flies, the effect of rearing on food spiked with different concentration of Paracetamol and Amitriptyline drugs on some biologicalaspects of the blow flies, The result showed the following : ? When using fly sex - attractant poisoned bait used in the field, six dipterans flies were identified : 1 - Calliphora vicina 2 - Lucilia sericata 3 - Chrysomya albiceps 4 - Ch. Megacephala 5 - Sarcophaga africa 6 - Musca domestica the last species was the most abundant during all seasons of the year. However, when natural food bait was used, the same species of flies were recorded in addition to three species of beetles : 1 - Dermestes maculates 2 - Saprinus semistriatus 3 - Necrobia rufipes. the results also showed that the daily activity of different flies species was the varied according to ambient temperature during the day andthere was no activity recording for the flies during the night. ? The succession of insects on rabbit carrion in the urban and rural area in winter season showed that the most abundant fly species attacking the carrion during the active stage, these flies were : : 1 - C. vicina 2 - L. sericata 3 - Ch. albiceps 4 - Ch. megacephala in addition to S. africa, M. domestica and three beetles namely : 1 - D. maculates 2 - S. semistriatus 3 - N. rufipes especially during the late stage of decaying, and recoded fly : Eristalis aeneus (Diptera) accidentally appeared on the carrion. However, less number of fly species were recorded on rabbit carcass during summer season.? In general the present study showed fly species : C. vicina and L. sericata Their numbers in urban area were more than the rural area (urban species) while fly species S. africa was rural species. ? 4) skeletonization time of the rabbit carcass during summer season was three times faster than it was in winter season in both locations, urban and rural.? When C. vicina larvae reared on different animal tissues, the result showed that there were a significant differences between means of larvae weight and development time and in the emergence of adults from pupal stage, thus, the average weight of larvae was 2337 mg 2101 mg when reared on lung and liver tissues as a compared with 998.6, 1194 and 1278 mg when reared on kidney, brain and muscles after eight days of exp - Time. However the longest development period of larvae were : 10.6, 10.3 and 9.3 days and pupae 7.3, 7 and 6.6 days when reared on kidney, brain and muscles respectively, as a compared with : 7.3, 7.6 and 8 days(larvae) 5.3, 5.6 and 6 days (pupae) reared on lung, liver and heart respectively (P? 0.05).The highest emergence percentage of adult were 46.6% and 40% in the lung and liver tissues. ? Larvae of C. vicina reared on 25 and 50gm beef liver /10 larvae were 83.2 and 75.6 mg respectively compared with 67.1 reared on 100gm/10 larvae during the first four days of the experiment. However, the duration period of larvae and pupae were 10.3 and 8 days when reared on 100gm respectively, the highest emergence percentage of adults were 46% and 26.6% for larvae reared on 25 and 50gm of liver. ?

دراسة تصنيفية حياتية مقارنة لانواع من الجنس Euphorbia L. (Euphorbiaceae) في العراق A Comparative Biosystematic Study of Some Species of The Genus Euphorbia L. (Euphorbiaceae) In Iraq

المستخلص: تناول البحث الحالي دراسة تصنيفية مقارنة لثلاث وعشرين مرتبة تصنيفية تعود جميعها للجنس Euphorbia L. من العائلةEuphorbiaceae النامية في العراق، تضمنت الجوانب المظهرية العامة والدقيقة ودراسة حبوب اللقاح والمركبات الكيميائية والبيئة والتوزيع الجغرافي فضلا عن ا | The current research deal with twenty - three taxa belong to the genus Euphorbia L., Family Euphorbiaceae grown in Iraq. The study included the gross general morphological and micromorphological characters, the Pollen grains also studied and the chemical compounds, Ecological and geographical distribution and taxonomic treatment have done.Also botanical key was putted to separate the species. General survey for the Phytogeographical districts where the taxa spread in, and the result was a large crowds of samples, and new locations of taxa distribution were recorded. The specimens studied, and correct the mistake naming, specimens were identified and reidentified some miss identified specimens in the Iraqi herbaria. A comparative morphological study was undertaken to all plants parts of taxa appeared from habit and duration of taxa to the quantitative and qualitative attributes the members of the vegetative and floral parts included the roots, stems, leaves, stipules, flowering parts and fruiting parts and drew charts diagrams, tables and accompanying with natural images for different morphological characteristics, as well as the field images. This study showed that all species was herbs, shrubs and succulent and semisucculent annual and perinnal, the major taxonomic importance was for flowering parts includeing the specific Inflorescence, installation of a cupped and its regularity on the branches of the plant, glands forms, numbers, presence or lack of appendages, bractes and bracteoles shapes, dimensions and color fruits shape, indumentum and seeds forms, dimension and her surface sculpturing; and the presence or lack of caruncle, as well as the qualities of roots, stems and leaves, and the morphological characteristics of all plant parts mentioned above have a taxonomic importance in identification and separation of the studied taxa. The study of the micromorphological characters of hairs, leaves epidermal cells and the stomatal complex which included anomocytic, paracytic, anisocytic and tetracytic, have a taxonomic importance of supporting the morphological characters in separation and identification of the genus taxa.The pollen grains have a taxonomic importance because their different in shape, dimensions of polar and equatorial view, the wall thickness and their ornamentation. They are mostly of Tricolporate except two species were Hexacolporate, also the differences in their shape in the polar and equatorial view.They were spheroidal, ovoid and oblate - spheroidal in the polar view and oblate, spheroidal, subprolate and oblate - spheroidal in the equatorial view.The ornomentation they were reticulate, microreticulate and foveoate.The chemical study also importance in separation of the genus taxa four compounds Flavonoids diagnosed in all the studing species but different in concentrations, by using HPLC, they are Myriscetin, Quercetin, Kaempferol and Coumarin esculetin and this confirms that there are a common evolutionary link between the species in terms of their chemical properties, which suggests belonging species to the genus Euphorbia.Through field surveys and information installed on the herbarium samples, the taxa where distributed on their growth areas, and maps have been drawn for taxa distribution in the Iraqi natural geographical districts. the species of Euphorbia were distributed in all Iraqi districts especially in LCA, MSU, MRO, and DWD and some species were farmed in gardens and nurseries either to the beauty of their bractes colors or because their acceleration to the environmental changes such as succulent species, As well as wild species were spread in mountainous areas, oak, nuts forests, in orchards, cultivated fields, flat plains and desert areas in loam soils, clay, gravel, and sand. Through this study some new taxa where founded in Iraq and they are E. cyparissias Kunth ; E. maculata L. ; E. serpens L. ; E. tirucalli L., and this study suggests to recorded them for the first time in Iraq.

تاثير بعض العوامل البيئية على نمو الاحياء الدقيقة في بعض القاعات الانتاجية لمصنع ادوية سامراء The Effect of Some Ecological Factors on The Growth of Microorganisms in Some Production Units in Sammara Drug Industry (SDI)

المستخلص: تم دراسة الظروف الطبيعية الموجودة في القاعات الانتاجية لمصنع ادوية سامراء من خلال العوامل البيئية التي شملت الحرارة، والرطوبة النسبية. وشدة الاضاءة واعداد حجم الدقائق العالقة في الهواء وتاثيرها على الاحياء المجهرية الموجودة في القاعات الانتاجية حيث تم اخذ | The natural environmental conditions existing in the production units of Sammara drug company have been studied. Environmental factors included, temperature, relative humidity, light intensity as well as number and size of suspended particles in the air. From December 2006 through June 2007. 87 sampling visit was made during which 384 swabs were collected from three production buildings : Ibn - Hayan, Ibn - Sina and Al - Zahrawy. Results showed that at different temperature levels during this study dominance of bacterial colony over fungal colony in two buildings Ibn - Hayan and Ibn - Sina, was observed, whereas the dominance of fungal colony over bacterial colony in Al - Zahrawy building was noticed. While the effect of relative humidity on microorganisms showed that in Ibn - Hayan building at low relative humidity (41 - 53%) the dominance of bacterial colony over fungal colony whereas the dominance of fungal colony on bacterial colony at relative humidity (53 - 62%). While in Ibn - Sina building bacterial colony dominante fungal colony except at high relative humidity (63 - 73%), where the fungal colony dominance. The same pattern have shown in Al - Zahrawy building at low relative humidity less than 51% while fungal colony exceeded bacterial colony at high relative Humidity. Result of the effect of light intensity showed that the low light intensity have greater effect on fungal colony than bacterial colony this clear in Ibn - Hayan and Ibn - Sina buildings whereas increases in light intensity showed the reverse while the low light intensity in Al - Zahrawy building shown different effects which the dominance of fungal colony over bacterial colony. This perhaps reflects the different species of fungal colony in production units.The effect of the number and the size of 0.3 micron of particulates on bacterial and fungal colony was also examined. It has been noticed that the dominance of bacterial colony over fungal colony until the number of particulates 49000/foot3 in Ibn - Hayan building, while fungal colony appeared in most swabs in Ibn - sina building, but dominancy for bacterial colony. While in Al - Zahrawy building the swabs showed clear appearance for fungal colony, but some swabs shown high bacterial growth. The effect of 0.5 micron particulates showed that the dominance of bacterial colony with increased number of particulates in Ibn - Hayan building. The same pattern was shown in Ibn - Sina building, while in Al - Zahrawy building it has been the dominances of bacterial colony until 15000/foot3, but with increase in number fungal colony appear very clear. The following bacteria and fungi were identified during the course of this study; Staphylococcus, E.coli and a low genera of fungi like Penicillium, Aspergillus, Mucor. It has been shown by the collected swabs that the contamination with bacteria and fungi of drug production units never exceeded the standard limits set by the company except in very rare occasions the high contamination rate occurred in the hands of workers and delivery boxes in Ibn - Sina building.

دراسة بيئية وسكانية للقوقع الارضي Candidula gigaxii (L.Pfeiffer, 1850) (Pulmonata : Hygromiidae) في مواقع مختارة من محافظة بغداد Ecological And Population Study of The Land Snail Candidula Gigaxii (L.Pfeiffer, 1850) (Pulmonata : Hygromiidae) In Selected Locations From Baghdad Province

المستخلص: Few studies on terrestrial snails in general, and garden snails in particular, existin Iraq. The group being important apparently for its wide - spread distribution in various habitats. One species of this group which has been previously recorded in Baghdad, is the garden snail Candidula gigaxii, class : Pulmonata, family : Hygromiidae.Available samples of the land snail C.gigaxii were collected from four locations within Baghdad province; a Taji, the Army Canal area, the Zafaraniyah, and Al - Jadiriya district, the study period of June 2013 to May of 2014.Environmental measurements were recordedat each site. Results showed that air temperature range was 10 - 34? C, soil temperature range was 5 - 26? C, pH range of the soil was between 4 - 8.9 and the content of the soil organic matter was between 0.3 - 2.0%.Snail samples were divided into seven size - classes according to the dimension of the shell and these were <2, 2 - 4, 4 - 6, 6 - 8, 8 - 10, 10 - 12, >12 mmPercentages of each size class were calculated. Having measured shell dimensions, shell growth index (Ia) was also calculated. The range of growth index value for this snail was 1.9 - 3.86 where the highest value was recorded at the Taji site in January 2014 which was probably attributed to low temperature range and high soil moisture and organic matter content.Results also showed that C. gigaxii favored soils with moderately high pH values and rich in organic content. Soil moisture appeared to be a limiting factor for growth; and a loamy soil texture for existence of the studied species. Average highest population density of living snails and empty shells were 44 and 32 individuals / m2 respectively. The overall population density was also calculated for the purpose of obtaining realistic population density of the species.

تاثير الاصابة بالاكياس المائية Hydatid cysts على مستويات مضادات الاكسدة في مصول المصابين The Effect of Hydatid Cysts Infection On Antioxidant Levels In Serum of Infected Individuals

المستخلص: اجريت الدراسة الحالية في محافظة ديالى اذ تم جمع 100 عينة من اشخاص مصابين وغير مصابين بداء الاكياس المائية للفترة من 2013/10/1 الى 2014/8/10 من مناطق مختلفة تابعة لمحافظة ديالى والتي شملت (حمرين، المقدادية، قزانية، بعقوبة)، وقد توزعت العينات بواقع 54 من ا | The present study was carried out in Diyala province during the period from 1/10/2013 to 01/08/2014 in different areas including : Hamrin, Muqdadiyah, Kasaniya, and Baquba.Blood samples were collected from one hundred individuals who are at risk of hydatid cyst infection (veterinarians, shepherds, farmers, butchers and housewives).The diagnosis of hydatid cyst infection was carried out by Echinococcus IgG ELISA kit. It was shown that the total rate of infection was 16% (6% for male, and 10% for female). The study revealed that the highest percentage of infection was in individual live in urban compared with those who live in rural area.The mean concentrations of antioxidants ; glutathion, catalase and superoxide dismutase were measured in addition to measure the mean concentration of the oxidants.The results showed the presence of malondialdehyde in the serum of studied individuals. The results showed a decrease in the level of glutathion catalase and super oxide dismutase in infected individuals (0.0048±0.0596mmol/L, 0.0220±0.0260mmol/L, 0.0024±0.04430 mmol/L, respectively) compared with non - infected individuals (0.0237±0.2719mmol/L, 0.0024±0.0879mmol/L, 0.0428±0.3069mmol/L, respectively) while there was an increase in concentration of malondialdehyde (0.2245±2.915mmol/L) compared with non - infected (0.025±0.8042mmol/L). There was no significant differences in the concentrations of all these parameters according to age, sex and location of the cysts. The results showed that there was no correlation between each of catalase and superoxide dismutase and the malondialdehyde whil there was a negative correlation between glutathion and malondialdehyde. The study concludes that the infection of hydatid cyst leads to a decrease in antioxidants and to an increase in oxidants which may indicate that there was a damage caused by tissue infection.

انتاج وتوصيف متعدد السكريات الخارج خلوي Lactobacillus plantarum من بكتريا Exopolysaccharide المعزولة محليا ودراسة فعاليته البيولوجية Production And Characterization of Exopolysaccharide (EPS) From Locally Isolated Lactobacillus Plantarum And Studying Its Biological Activity

المستخلص: Twenty - five isolates of Bacillus spp. Were isolated from 15 soil samples collected from different places in the Holly city of Kerbala, 13 isolates lactobacillus spp. Were isolated from 15 milk products and 7 isolates pseudomonas spp. The isolates were screened for their ability to produce Exopolysaccharide.The results showed that isolate number 3 (Lactobacillus lac 3) was found to give the highest production of the polymer, the isolate has been identified as lactobacillus plantarum. The optimal cultural and environmental conditions for EPS production were been identified which include using the production medium (simplified synthetic medium) containing date juice (5%) as a carbon source and yeast extract (0.2%) as a nitrogen source, the media was enhanced with a total concentration 0.9% of magnesium sulphate and potassium phosphate as mineral salts. The primary pH was adjusted to 6.5 and the inoculum size was 3%(v/v), isolates were grown under anaerobic condition at 35 Co for 24 h and the EPS extracted with ethanol 95%. Two steps were used for partial purification of the polymer as follows, the first step by using TriChloroAcitic acid (TCA) solvent and the second step by dialysis. The yields were (77.4 and 63.8)% for the two purification steps respectively. The biological activity of the EPS extraction from L. plantarum has been tested against some species of G+ve and G - ve bacteria and some fungal. The results showed that EPS extrac exhibits an inhibitory activity against Stenotrophomonas, Bacillus cereus and Proteus bacteria with an inhibition zone diameter of 23, 21, 19 mm respectively. While, there was no inhibitory effect against fungi. Antioxidant activity has also been tested, where IC50 value against ABTS free radical at 100 Mg / ml. The characterization of partially purified EPS is investigated by using Fourier Transform Infrared Spectroscopy (F.T.I.R). The molecular weight of the polymer was also measured by using viscometer and the molecular weight obtained by this technique was 2.3 *105 Dalton. The EPS extraction from selected isolate showed two spots when separated by Thin Layer Chromatography (TLC) which is analyzed as a glucose and galacto

التشخيص الجزيئي وخصوصية المضيف لداء الابواغ الخبيئة Cryptosporidiosis في بعض انواع الطيور البرية والداجنة ود راسة الاصابة التجريبية في الفئران البيض Molecular Diagnosis And Host Specificity For Cryptosporidiosis In Some Species of Wild And Domestic Birds And Study of Experimental Infection In White Mice

المستخلص: The present study aimed to investigate of Cryptosporidiosis in some wild and domestic birds, and study some concerned aspect of it such as : Host specificity for Cryptosporidium spp., histo - pathological changes which parasite produced it and molecular analysis for this species. To attainment this purpose we applied our study in three major parts : The First part : Investigation of Cryptosporidium in birdsA total of 236 birds were collected from different regions of Al - Diwaniya province between May 2013 to June 2014, Birds included six species which are : 22 sample from Turkey (Meleagris gallopova), 60 from Quail (Coturnix coturnix) , 40 from Domestic chicken (Gallus gallus domesticus), 52 from Caged chicken(Gallus gallus), 32 from Common duck (Anas platyrhynchos) and 30 from Feral pigeon (Columba livia). Fecal and bile samples which took from birds were examined by used hot modified Zeihl - Nelseen stain.Results revealed that the birds were infected with two types of Cryptosporidiosis : Intestinal and Biliary Cryptosporidiosis (58.1% and 12.7% respectively).Our study recorded four species belong to Cryptosporidium be responsible for intestinal type which are : C.parvum, C.meleagridis, C.baileyi and C.galli, While just the first three species of them were be responsible for biliary type.Also results showed that no significant difference according to gender of birds in infection with two types of Cryptosporidiosis, while showed a significant difference to study's months in infection, the highest ratio of Intestinal type was in March and April (87.5% and 89.3% respectively) and the lower ratio was in July, it reached 27.8% ; While the highest ratio of biliary type was in April, it reached 39.3%.Also results revealed that all cases of Biliary type were light infection, while the severity of infection with Intestinal type was between heavy and light infection. Quail birds showed a significant difference in severity infection compared with other birds, it was higher in quail which reached 60.9% and lower in common duck(30.0%) and there was no heavy infection in feral pigeon. when reading of preparation histological sections from : intestinal, fabricious bursa and bile sac, the results showed a histological changes that parasite induced it which included : hyperplasia in infection's regions, necrosis and destroyed in infected cells with infiltration of inflammation cells.The second part : Experimental studyTo test a host specificity and to know how incidence of cross transmission of Cryptosporidium species which isolated from birds to human, therefore the laboratory mice were dosage with the four species of parasite and then we determinate of : susceptible of age group to infection, prepatent period and histological changes in experimentally infected mice.Result showed that cross transmission could happened for three species of Cryptosporidium that infected birds to lab. mice which are : C.parvum, C.meleagridis and C.baileyi with total ratio 30% and showed a significant difference compared with control group, and the results recorded a mortality ratio in infected mice (7.5%).The probability of mammalian infection by Cryptosporidium spp. which isolated from birds in our study represent the first record in Iraq. C.parvum and C.meleagridis showed loss of host specificity whereas C.baileyi was opportunist in his ability to infect another host beside their ordinary host (birds), while C.galli showed a high specificity for its host.The third part : Molecular studyThis part in our study studied for the first time in Iraq, which contains the diagnosis of Cryptosporidium species that infected birds and their genetic analysis through : DNA sequence analysis of species by used small subunit ribosomal RNA gene (18SrRNA), read of phylogenetic tree of these species and do comparison among genetic trees according to : original host (birds), experimental host (infected mice) and to their parasitic site in their ordinary host.The phylogenic tree of parasite species was drown by used MEGA6 program, the results of neighboring tree revealed two major branches : First branch include C.galli while the second branch include the other three species. Also genetic tree showed presence of two difference strains of C.parvum can infected the birds with neighboring ratio between them reached to 82% and the same thing was found for C.meleagridis but with neighboring ratio reached to 70%.The reading of phylogenetic tree showed that all species of studied birds can infection with isolated Cryptosporidium species excepting C.galli which just isolate from domestic chicken and C.meleagridis which found parasite only in turkey and quail.Results of genetic analysis of neighboring tree among species according to parasitic sites in infected birds showed similarity between species which isolated from fecal and bile, which are : C.parvum, C.meleagridis and C.baileyi, this result corroborate the ability of these species to transfer their infection from intestine to bile sac.The results of comparative concerned with isolated species from infected mice's fecal(experimental host) and from birds' fecal (ordinary host), results showed similarity among three species which isolated from mice's fecal with their analogous species isolated from birds' fecal which are : C.parvum, C.meleagridis and C.baileyi, while C.galli doesn't have ability to infect mice which dosage it.Finally the result of this study give evidence to ability of cross transmission for these three species from the class : Aves to the class : Mammalian, So this fact give to us a hygienic indication for probability of human infection with these species.

انتشار بكتريا Escherichia coli في المرضى في المرضى المصابين بالتهاب المرارة الحصوي في محافظة الديوانية Dissemination of Escherichia Coli In Patients With Cholecystitis Calculus In Al - Diwanyia Governorate

المستخلص: The study aims to identify Escherichia coli bacteria, which causes calculus cholecystitis of molecular perspective. The study samples were gathered from 110 patients who undergone cholecystectomy in Diwaniya general hospital for the period October 2013 to April 2014. The sample included bile sap, gall bladder tissues and stone if available. The samples were cultured to identify their culture specifications.The results showed that chronic cholecystitis is the most common one, which has 55.5% then acute cholecystitis by 44.5%. The study results showed that age and sex have an influence on cholecystitis. The highest percentage of infection is the ages 36 - 45 for the two sexes. If the cases distributed according to the patient sex, there is a difference in cholecystitis between male and female, where females infections are 88.2% and males are 11.8%. The total isolated bacteria were 125 bacterial isolates of 52% of gall bladder tissues, 26.4% of bile and 21.6% of the stone. Escherichia coli had 34.4% of the total samples of 51.1%, 36.6% and 29.6% respectively of the above mentioned samples.As far as susceptibility for all Escherichia coli isolates towards 15 types of antibiotics by using disc diffusion for Kerby - Bauer method, bacteria had high susceptibility against ? - lactamases antibiotics where they had susceptibility against Ampicillin+ Clavulanic acid by 38.7% and 79% for Ampicillin. The least susceptibility was for Amoxicillin by 69.7%. Bacteria had no resistance for Imipenem where their susceptibility was 100%. Bacteria had weak susceptibility against Aztreonam by 13.9%. While with cephalosporins, susceptibility for Ceftazidime by 27.9% and for Cefotaxime by 20.9%. With Aminoglycosides, resistance to Gentamicin antibiotics was 34.8% and 30.2% for Amikacin. The results showed that resistance to Quinolones was 16.2 for Nalidixic acid while for fluoroquinolones resistance was 25.5% for Ciprofloxacin and 18.6% for Norfloxacin. Isolates ability to produce CTX - M, SHV, TEM and AMPC extended spectrum ? - lactamases enzymes was tested by investigating the existence of blaTem, blaAMC, blaCTX - M and blaSHV genes in these isolates through Polymerase chain reaction (PCR). There were 23/26 isolates (88.4%) showed their ability to contain blaAmpC gene, and 7/26 isolates (26.9%) contained blaSHV gene. There are 18/26 isolates(69.2%) contained blaTEM gene while 20/26 isolates (76.9%) contained blaCTX - M.Through using Quantitative Real Time - Polymerase chain Reaction (qRT - PCR), gene expression measurement for blaCTX - M, blaTEM and blaAmpC was measured by relative numbers. The results showed that gene expression measurement for ? - lactamases enzymes type AmpC produce by Escherichia coli was the highest if compared with ? - lactamases enzymes type TEM and CTX - M with different periods of incubation, which is T4h for 4 hours, T24h for 24 hours and T48h hours of incubation respectively. It is noticed that genes responsible for producing ? - lactamase enzymes type TEM, CTX - M and AmpC are changed during different periods of incubation through using Real Time - Polymerase chain Reaction (RT - PCR).

تاثير بعض العوامل البيئية في مجتمع الهائمات القشرية لنهر دجلة وجزيرة بغداد السياحية - العراق The Effect of Some Environmental Factors In Crustaceans Plankton Community of The Tigris River And The Island of Baghdad Tourist - Iraq

المستخلص: The present study was conducted to investigate the effect of the water body type on the density of crustaceans zooplankton of the cortical Cladocera and two orders of copepod (Cyclopoida, Calanoida), addition to the physical and chemical effect of lake of Baghdad Tourist Island and Tigris river within the water of the lake near the site and electric and know the effect these characterties on density of crustaceans Zooplankton and for doing this study. We choose five places, tow on Tigris river and three places on the Island in AI - Fahhama in north of Baghdad The samples of water were collected every 15 days all these stations from beginning of December 2013 to May 2014. This study had corrected the temperature of air and water and the pH, electrical conductivity. and Dissolved oxygen, BOD5, NO?¯, PO?¯ and the density of Crastaceans Zooplankton. This study showed that the temperature of the air was nearly in the river and the lake and that because of their being in the same geographs area.The temperature was between (16°c - 34°c)in Tigris while it was (11.9°c - 33°c)in the lake Hydrogen Ions, it was (7.3 - 7.9) in the river and (8.18.8)in the lake because that were a lot of water plants and phytoplankton. This study shows that water of the river and the lake in the areas of study have a good of air and that was shown by recording the heigh values of oxygen. The values of dissolved oxygen (DO) was between (8.11 - 11.5) mg\L in river between (7.9111.37)mg\L in lake and showed from the study that the values were few. It was less than 5mg\L it was (0.33 - 2.6) mg\Lin the river and (0.64 - 3.55) mg\L in the lake. The values electrical conductivity of water in all the placed the study in the permissible range the water, it isn't over than 1500?s\cm. The electrical conductively records were between (851 - 1184) ?s\cm in the river, and it was (755 1270) ?s\cm in the lake. From the other hand nutrients, the phosphor records between (0.025 - 0.0563)mg\Lin the river and in the lake between(0.00310.0429)mg\L The Nitrate records its values highs in the month of winter because of the rain and it was increased in the river, it was (0.345 - 0.9135)mg\L compare with the lake, it was (0.028 - 0.626)mg\L in the places of the study that were appearance of two clear increases in the density of Zooplankton one was in winter and the other was spring.The density of zooplankton in the lake much more than it was in the river. The density of the zooplankton belong to Cladocera between (0.019 - 0.307) ind.\L in the lake and the density of the Calnoida was between (0.003 - 0.065)ind. \L in the river and (0.0078 - 3.37) ind. \L in the lake. The results shows differences if there are changes in places and month on most of physical and chemical biological characteristic the measured during the period of this study. The kind of water body effects on most characteristics and soon the density of crustaceans zooplankton.the results of the study mention the binding morale relation between the density of zooplankton the values of electrical conductivity and value of BOD(Biological Oxygen Demand) while there isn't any morale relation between the density of zooplankton and the value of Hydrogen Ion and Nitrate and dissolved oxygen that because the value of these changes was near to be equal in all the places that eayses the reduce of its effective on the average of density of these organism. The study shows that Baghdad lake have the environmental ingredients makes the lake natural protected to forming and breeding a fish in the lakes in addition that it is a place for Tourism.

تاثير عصارة نبات البروكلي في متلازمة تعدد الاكياس المبيضية المستحدثة في الجرذ الابيض Effect of Broccoli Plant Juice On Induced Polycystic Ovarian Syndrome In Albino Rats

المستخلص: The goal of present study was to investigate the benefits of broccoli as anti androgenic plant in protection and treatment for reproductive hormonal and metabolic disturbance, which combined with polycystic ovarian syndrome (PCOS). Three experiments for 3 PCOS models were done. First Experiment : The prepubertal female rats at 21 days old, were injected with Testosterone (T) subcutaneously for 39 days (first model). The females of this experiment were divided into 6 groups (8 rats each) as follows : Group 1 was injected with sesame oil. Group 2 was injected with T hormone. Group 3 was injected with T hormone with orally gavaged of broccoli juice. Group 4 was injected with sesame oil, and at the end of the last injection was orally gavaged with distilled water for 30 days. Group 5 was injected with T hormone, and at the end of the last injection was orally gavaged with distilled water for 30 days. Group 6 was injected with T hormone, and at the end of the last injection was orally gavaged with broccoli juice for 30 days. Second Experiment : The prepubertal female rats at 21 days old, were injected with Letrozole (L) subcutaneously for 39 days (second model).The females of this experiment were divided into 6 groups with the same style of the first experiment. Third Experiment : it was achieved by the injection of pregnant rats prenatally (days 16 to 19 of gestation) with 1 mg of T hormone subcutaneously (third model), and then the female offspring were divided into groups (8 rats each) as follow : The first offspring group : The female rats offspring at 21 days old (their mothers were injected with sesame oil from 16th to 19th day of gestation) were orally gavaged with distilled water until 60 days of age. The second offspring group\ gavaged with distilled water : The female rats offspring at 21 days old (their mothers were injected with T hormone from 16th to 19th day of gestation) were orally gavaged with distilled water until 60 days of age. The second offspring group\ gavaged with broccoli juice : The female rats offspring at 21 days old (their mothers were injected with T hormone from 16th to 19th day of gestation) were orally gavaged with broccoli juice until 60 days of age. The third offspring group : The female rats offspring at 21 days old (their mothers were injected with T hormone from 16th to 19th day of gestation and orally gavaged with broccoli juice) were orally gavaged with distilled water until 60 days of age. Females of all groups were sacrificed after 24 hours from the last treatment to undertake weight, histological, hormonal and metabolic study for each group. the results of present study showed the symptoms that reported PCOS of the three female experiments such as ovarian cyst, hyperandrogenemia, hormonal and metabolic disturbance, etc. Also a well improvement has been noticed in all syndrome symptoms on females gavaged with broccoli juice for all three rats PCOS experiments, these results indicate that broccoli juice has got a protective and curative role against this syndrome.

In the pregnant women, S. saprophyticus was the most isolated bacteria 48.10 % followed by E. coli 20.25 % and S. aureus 12.65 %, and in the diabetic women, S. saprophyticus was the common isolated bacteria 32.07 % followed by E. coli 28.30 % and S. epidermidis 15.09 %. In the hypertensive women, S. saprophyticus 30.35% was the common isolated bacteria followed by E. coli 25.0% and S. aureus 19.64 %. In the case of diabetic pregnant women, and in the hypertensive pregnants S. saprophyticus was the most isolated bacteria, (80 % and 75 % respectively), while E. coli 44.4% was the common isolated bacteria among the diabetic hypertensive women. Out of all isolates, S. saprophyticus 35.13 % came in the first rank followed by E. coli 26.64% and S. aureus 12.74% while Klebsiella oxytoca and Serratia odorifera (0.38% for each of them) were the lowest isolates. Urinary tract infection was common among urban patients 57.49%.The isolated bacteria showed different susceptibility to the antibiotics used in this study. S. saprophyticus isolates showed high sensitivity to Amikacin, Nitrofuratoin and Cefolaxime (the resistance rate for these antibiotics were 11 %, 12.1 % and 12.1 % respectively). While these isolates showed high resistance to Streptomycin 76.9 %, Nalidixic acid 67 % and Cephalexin 69.29 %. E. coli isolates showed low resistance rate to Amikacin 9.28 %, Ciprofloxacin 10.1 %, whereas showed high resistance rate to Cephalexin 47. %, Streptomycin 84 % and Ampicillin 82.6 %. The isolates of S. aureus showed low resistance to Ciprofloxacin 18.2 %, Carbencillin 18.2 % and Amikacin 15.2 % and high resistance for Ampicillin 18.8 %, Nalidixic acid 75.8 % and Cephalexin 72.79 %. Other isolated bacteria showed a different percentages of susceptibility to antibiotics Serratia odorifera, Proteus vulgaris and Enterococcus faecalis showed a significant resistance to antibiotics, while S. epidermidis isolates showed low percentages of resistance to Ciprofloxacin 9.1 %, Amikacin 18.2 % and Gentamicin 9.1 %. For S. saprophyticus the minimal inhibitory concentrations (MIC) resulted from Ciprofloxacin, Gentamicin and Cefotaxime were 8 - 32, 8 - 64 and 4 - 8 ?g/ml, and for E. coli the MIC results were 2, 8 - 16 and 16 - 64 ?g/ml. The MIC results were 2 - 8, 8 - 128, 32 - 256 ?g/ml for S. aureus, while the MIC results were 8 - 32, 16 - 64 and 16 - 128 ?g/ml for Klebsiella pneumoniae.

دراسات وراثية خلوية ومظهرية لثلاثة انواع من شبوطيات المياه العذبة العراقية (Barbus luteus, Cyprinion macrostomus, Chondrostoma regius) Three Species of Iraqi Freshwater Cyprinidaes (Barbus Luteus, Cyprinion Macrostomus, Chondrostoma Regius)

المستخلص: هدفت الدراسة الحالية التعرف على الطراز الكروموسومي ونظام تحديد الجنس والتمييز بين الجنسين مظهريا في ثلاثة انواع من اسماك المياه العذبة العراقية ممثلة بسمكة الحمري Barbus luteus والبنيني كبير الفم macrostomus Cyprinionوالبلعوط الملوكي Chondrostoma regius | These present studies were carried out to determine the karyotypes & the system of sex determination between the two sexes as well as the sexual morphological characteristics of three species of Iraqi fresh water fish Barbus luteus, Cyprinion macrostomus, & Chondrostoma regius that were fished from Tigris river at Baghdad during 2005. The cytogenetic studies revealed that the chromosome number of Barbus luteus is 2n = 148 & the karyotype of males is (80m + 52sm + 16st) while the females has (80m + 51sm + 17st). The chromosome number of Cyprinion macrostomus is 2n = 50 the males has (6m + 24sm + 12st + 8t) while the females has (6m + 23sm + 13st + 8t). The chromosome number of Chondrostoma regius is 2n = 48 and the karyotype is (14m + 30sm + 4st). Sex chromosomes were identified in Barbus luteus & in Cypinion macrostomus for the first time , the sex is determined by ZZ / ZW system, the female was considered as heterogametic (ZW) while the male was considered as homogametic (ZZ) , & the chromosome Z was represented as submetacentric chromosome & chromosome W as small subtelocentric chromosome. In spite of the difference in their chromosome number , the ratio between red blood cell diameter & it's nucleus was approximated in these species. The differences among these species in both of the diameter of cell and the nucleus didn't match with the differences at the polyploidy levels or with the difference in chromosome number within the same level. The liver & intestine were recommended as new sources for chromosomal studies , because of the good ratio of dividing cells (71.4 % & 58.2 %) respectively from the whole dividing cells in kidney that was considered as a control. The crude aqueous extract of fresh convolvulus arvensis leaves showed good effect in arresting the cell division of fish at metaphase , the concentration (0.4, 0.6, 0.8, ) mg / gm arrested kidney cells of carp fish at the metaphase in ratios 71.1 % , 88.1 % , 94 % respectively from the colchicines treated kidney cells (control). Positive significance correlation was found (r = 0.9518) between the percentages of arrested cells at metaphase & the concentrations of crude extract. Comparison between the females and males of the three species revealed that in Barbus luteus the distance from head edge to the anal orifice & from head edge to the dorsal fin were larger in males than females. The females have dark colored fins with reddish ventral aspect of head & body in comparison with the males during the whole months of study. So , they were considered as permanently sexual dimorphism characteristics. But , during the spawning seasons (May & June ) a more brighting color of male with reddish coloration of both sides of body were noticed in comparison with female with a golden orange corneal coloration in both sexes. Thus, they were considered as temporary sexual dimorphism characteristics. In Cyprinion macrostomus the distance from the head edge to the anal orifice was larger in females than males. The colors of anal & caudal fins were darker in females than in males during the whole monthes of study.So , they were considered as perminantly sexual dimorphism characteristics. While, during the spawning seasons ( May , June , July & August) , the gill operculum was of orange color only in male that extend to the end of pectoral fin. So , this was considered as a temporary sexual dimorphism characteristic. In Chondrostoma regius the distance from the head edge to the dorsal fin & from the dorsal to caudal fin as well as the pectoral fin base length were larger in females than in males during the whole months of study it was considered that they are permanently sexual dimorphism characteristics. Differential characteristics were not noticed during the spawning season (February & March). The permanently sexual dimorphism & the general characteristics were not affected by the differences of standard length , weight , age & season , because they were observed in fishes of different lengths , weights & ages & during the months of study 2005. But , the seasons affect the development of temporary characteristics in Barbus luteus & Cyprinion macrostomus , because these characteristics were observed during the spawning season only. Aging of Barbus luteus was accompanied by growth increase as indicated by the mean of standard length during May , July, August, September & December & by the mean of weight during May , August, September, October & December. A positive correlation was found between standard length & weight during the months of study , with the exception of January. While aging of Cyprinion macrostomus & Chondrostoma regius was not accompanied by growth increase as indicated by the means of standard length & weight , but a positive correlation between standard length & weight was found during the studied months. Same growth type were observed in the three species of fish , it was allometric in two sexes.

دراسة تصنيفية لبعض اجناس العائلة المركبة Asteraceae في العراق Taxonomical Study of Some Genera From Asteraceae In Iraq

المستخلص: تناول هذا البحث دراسة تصنيفية مقارنة لستة اجناس تعود للعائلة المركبة Asteraceae وهي Chrysanthemum L. وGazinia وGerbera وLeontodon L. وTagetes L. وZinnia L. وتميز كل جنس من تلك الاجناس المذكورة باحتوائه على نوع واحد فقط في العراق وهيL. Chrysanthemum coro | The present investigation comprises systematic study for six genera belong to Asteraceae as follow : Chrysanthemum L., Gazinia, Gerbera, Leontodon L., Tagetes L. and Zinnia L. Each genus of those genera described as containing only one species in Iraq, Chrysanthemum coronarium L., Gazinia splendens Gaertn, Gerbera jamisoni F.Gmel, Leontodon laciniatus L., Tagetes patula L. and Zinnia elegans L. respectively. The study was conducted in the laboratory research of plant taxonomy / College of Science women / Babylon university for the period January 2015 until August 2015.The study included morphological, anatomical, palynological and chemical characteristics as well as numerical taxonomy have been done for all species. The importance of taxonomic to studying variations in roots, stems, leaves, inflorescences, involucre bracts, flowering and fruiting parts and Indumentum were discussed. Results showed that many of the vegetative and reproductive characters have the importance taxonomic value for isolating genus from each other such as presence and absence of the stem and the nature of the basal and cauline leaves in addition the present of leafy stipule as well as the nature of Indumentum.Anatomical characters of leaves epidermises and the cross section of the stem, leaf blade, petiole and peduncles, in addition leaves venation have been studied and their taxonomic importance were assessed.The study also found the pollen grain was tricolporate in general, but the presence of spine or not had an important taxonomic to isolate Gerbera jamisoni by smooth surface compared to the rest of the species, while possible to isolate Gazinia splendens and Leontodon laciniatus by the presence of the bridges in pollen surface. On the other hand it has been the study of chemical content in each of the leaves and flowering heads of the species studied using Gas Chromatography technique (GC) to detect the terpenoid compounds, The presence of compound Nerolidol, Terpinolene in the species.. Gerbera jamisoni, Zinnia elegans emphasized the importance taxonomic chemical content at the level of species and genera.The species were numerically treated on the basis of number of selected characteristic from various studies to obtain the similarity and differences ranges between different species. Dendrogram was drawn for this purpose. As a result of preceding observation this study confirmed the diagnosis of six genera within Asteraceae family in Iraq. Finally all the taxa were treated taxonomically, and the key was prepared for all the taxa studied.
