Pages: 1-8

Abstract

A total of 109 fish specimens belonging to six species (Barbus grypus, B. luteus, B. xanthopterus, Cyprinion macrostomum, Cyprinus carpio and Liza abu) were collected from Tigris river passing through Salah Al-Deen province during the period from September 2008 till January 2009. These fishes were infected with nine parasite species which included two sporozoans (Myxobolus mÃ¼lleri and Dermocystidium percae), three ciliates (Trichodina cottidarum, T. elegini and T. murmanica) and four monogenetic trematodes (Dactylogyrus rhodeianus, D. vastator, Paradiplozoon cyprini and Microcotyle donavini). Among these parasites, two trichodinids (T. elegini and T. murmanica) were reported for the first time from fishes of Iraq. Also, B. grypus is considered as a new host in Iraq for both D. percae and M. mÃ¼lleri. Apart from D. vastator and P. cyprini, all the remaining seven parasite species were recorded here for the first time from fishes of Salah Al-Deen province. Among the inspected fishes, both B. grypus and L. abu harbored the highest number of parasite species (three each), followed by C. carpio (two parasite species) and B. luteus (one parasite species)

Abstract

An experiment was carried out by using pots in kalar horticulture station/ Sulaimani province on soil which is talken form on once region field in the seasoning growth(20062007). The objective was to study interaction of different levels from urea fertilizer (zero, 0.20, 0.40, 0.80 gm / 4 kg soil in pot). These levels were equal to (zero, 25, 50, 100, kg uera / D) and super phosphate levels (zero, 0.24, 0.48, gm / 4 kg soil in pot).These levels were equal to(zero, 30, 60, kg / D) in morphological and physiological characteristies (ex. dry weight, leaf area, absolute growth rate, protein percentage, and chlorophyll content) of Ipa (95) wheat variety. This experiment was carried out by completely Randomized Design (C. R. D.). Results indicated a clear increase in all the studied characteristics with the increase of urea and super phosphate levels added to the pots. The levels (100 kg urea / D and 60 kg super phosphate / D) were best in giving high values of these characteristics comparative with other levels from these fertilizers.

Abstract

For the first time, the life cycle of Neoechinorhynchus iraqensis, a parasite of Liza abu and other freshwater fishes in Iraq and its larval development in the intermediate host, the copepod Cyclops hyalinus was given. Hatching took place in the intestine of the copepod host within 10 minutes of exposure to the infective eggs. Motile acanthor penetrated the wall of the intestine within 2-4 hr. after exposure and was found free in the hemocoel where it metamorphoses through the acanthella stage. Acanthella stage revealed changes in the entoblast where the anterior section gave rise to brain, proboscis and proboscis receptacle. The posterior section differentiation gave rise to the genital system. By 12 days, development in the copepod apparently was completed and by 13-14 days, the juvenile was infective for the definitive host.

Abstract

Laboratory experiments were carried out in Technical college AL- Mussiab / Babylon during 2005 to study bioactivity of different concentration from ( aqueous , alcohol and hexane) extracts of bee venom collected from different workers of bees against some bacterial types that cause European Foul â€“ brood Melissococcus plutom , Bacillus alvei and B. letrosporus which had been isolated from infected arched with disease . Two diffusion methods (digging and paper discs) were followed for the extraction of the venom . Results showed that digging diffusion method was more efficient for test of bacterial inhibition which led to increase the activity of bee venom extract with general average 7.90 , 8.85 and 8.19 on M. pluton, B. alvei and B. letrosporus. Alcoholic bee venom extract showed high efficiency in inhibition for the same bacterial species above by digging method too with diameters average 8.15 ,9.76 and 10.59 mm respectively . while aqueous extract was the less efficient in bacterial growth of these bacterial species that reached 7.26 , 7.70 and 6.26 mm respectively in paper discs method compared with control 6.00 mm. On the other hand 40% concentration of bee venom showed high effect of bacterial growth for M.pluton , B. alvei and B. letrosporus with averages 10.60 , 15.60 and 15.60 mm respectively while 1% concentration had no effect in growth of these bacteria compared with control treatment 6.00 mm .Ther is an interaction between the diffusion method, concentration and the kind of the extract . The results reflected that Alcoholic extract at 40% con. by digging method gave a higher inhibition of growth 10.60 , 15.60 and 15.60 mm in M. pluton , B. alvei and B. letrosporus respectively. 40% con. of bee venom compounds however was more effective for bacterial species compared with Oxytetracyclin antibiotic that was very effective in B. alvei and B. letrosporus and less effective in M. pluton bacteria .

Abstract

The anticestodal activity of the crude aqueous extract of Cucurbita pepo seeds was
carried out on mice experimentally infected with Hymenolepis nana. Significant effects
were obtained by reducing the number of eggs and worms when compared with the control
group. Five concentrations of C. pepo aqueous extracts were used (125, 250, 375, 500 and
625 mg/kg). These concentrations produced deparasitization rates of eggs of 52.7 , 61.6 ,
84.2 , 89.4 and 100 , respectively at the fourth day of the treatment. Also, more potent
effects were obtained with highest concentrations especially 500 mg/kg and 625 mg/kg
which gave a total eradication of H. nana eggs and worms at the fifth and fourth days of the
experiment, respectively.

Abstract

A new approach presented in this study to determine the optimal edge detection threshold value.
This approach is base on extracting small homogenous blocks from unequal mean targets. Then,
from thes e blocks we generate small image with known edges (edges represent the lines between the
contacted blocks). So, thes e simulated edges can be as sumed as true edges .The true simulated edges,
compared with the detected edges in the small generated image is done by using different
thresholding values. The comparison based on computing mean square errors between the simulated
edge image and the produced edge image from edge detector methods. The mean square error
computed for the total edge image (Er), for edge regions (Erl), and for non-edge regions (Er2). From
these measures (Er, Erl, &Er2), we can es timate best threshold value, at low edge errors detection
(i.e. bes t (th) at low Er, Erl,&Er2).

Abstract

Modification of gas chromatographic technique for the separation and determination of
methyl ethoy silane compounds which were s ynthesized by the addition of absolute ethanol to
methyl chlorosilane compounds have been elaborated experimentally. The addition of
absolute dry ethanol to methyl chlorosilane compounds in the presence of a dry stream of
nitrogen gas led to sweep out the liberated HCl gas. This method was found to be the suitable
method for the preparation of methyl ethoxy silane compounds . The optimum parameter
selected after careful and precise studies was between 20 – 30 ml \ min to carrieir gas flow
rate, while applied temperatures of detector and injection part were 250 °C and 225 °C
respectively. The results showed that suitable chromatographic column for the separation of
methyl chloro silane compounds is 50% [5% dioctyl phthalate ] + 50% [10% OV- 101 ]
.While 10 % OV – 101 column was found to be the best for the separation of methyl
ethoxys ilane compounds . Accordingly , a linear relationship for the calibration curve
between concentration and peak area is achieved for methyl chlorosilane and methyl
ethoxys ilane . Correlation coefficients here ranged between 1 – 0.9991. The results of
percentage RSD alotarned for the methyl chlorosilane and methyl ethoxys ilane were 0.51-
2.08 and 0.053-1.37 respectively.
