The protein in broken-cell extract from Trichophyton mentagrophytes var.erinacei
was isolated and fractionated using sephadex G-100 gel filtration technique. On ultra-violet
absorption of the isolated fractions was measured at 280 nm. the molecular weight of these
fractions was calculated and found to be four fractions ranging :102,000,220,000,425,000
and 610.000 Daltons. Amino acid analyses showed a predominance of the following: glutamic
acid ,glycine ,proline,valine,methionine and cyctine.In conclusion the information derived
may be useful in the classification of Trichophyton species.

Monthly variation in the quality and quantity of zooplankton was studied in Shatt Al- Basrah and Khour Al-Zubair Channels, Basrah, Iraq, during March, 2009 to May, 2010. Samples of zooplankton were collected by plankton net (0.120 mm. Mesh size). In Shatt Al- Basrah Channel, the population density of zooplankton ranged between 5811 – 95514 Ind./m³ during August and April, 2009 respectively. The results showed that the Crustacea was the dominated group 62.9 %. Copepoda constituted about 44.7 % followed by Rotifera 31.0 %, Cirripede larvae 14.7 % , polychaetes 5.5 % and Cladocera 3.1 %. While in Khour Al-Zubair Channel the population density of zooplankton ranged between 3548 and 20328 Ind./m³ during January 2010 and October 2009, respectively. Crustacea was also the dominant group
83.7 % Copepoda formed about 66.6 % , Cirripede larvae and megalopa of crabs 8.4 % , Gastropoda 6.1 % and polychaetes 2.3 %.

Cu(II) and Co(II) complexes were prepared by the reaction of metal ions with Nystatin
in (1:1) and (1:2) metal ratio, respectively. These complexes were characterized by IR ,UV-Vis spectroscopy and conductivity measurements.All complexes shows relatively high antibacterial activity againstS.aureus andE.coli whereas Nystatin has no antibacterial activity against the same bacteria. All complexes are weak electrolytes in DMSO solution .

Inflammation is the complex biological response to a protective attempt to remove the injurious stimuli, most strongly implicated are prostaglandins (PGs), leukotrienes (LTs), histamine, bradykinin, platelet activity factor (PAF) and interleukins. The Phenytoin is a drug used for the treatment of antiepileptic. Phenytoin acts to suppress the abnormal brain activity seen in seizure by reducing electrical conductance among brain cells by stabilizing the inactive state of voltage gated sodium channels, Phenytoin (5,5-diphenylimidazolidine-2,4- dione) were prepared from benzil and urea with sodium hydroxide in absolute ethanol. The derivative of phenytoin was prepared from a histidine acidifies with hydrochloric acid in absolute ethanol and phenytoin to give phenytoin-3-histdine IUPAC name is (S)-3-(2-amino- 3-(1H-imidazol-4-yl) propanoyl)-5,5-diphenylimidazolidine-2,4-dione.
The identifications were performed by measuring the melting point, the Fourier transform infra red (FT-IR) spectra and elemental analysis (CHN). The Carrageenan induced inflammation model was used to determine the anti-inflammatory activity. The Inflammations were induced by sub-plantar injection of homogenous suspension of (1%) carrageenan in water. The Phenytoin derivative (with histidine) has significant (p<0.001) anti-inflammatory activity. The presence of imidazole ring in the compound (as in phenytoin and histidine) increased the activity. So it resembles some of the non-steroidal anti- inflammatory drugs in its structure. It was predicted that the phenytoin derivative will act as an anti-inflammatory agent, through the inhibition of biosynthesis of prostaglandins and inhibitor for cyclooxygenase-2 enzyme (COX-2).

In the present work methyl methacrylate-co-acrylic acid (MMA-co-AA) hydrogels were synthesized by free radical copolymerization of methyl methacrylate (MMA) and acrylic acid (AA) using methylene bisacrylamide (MBA) as crosslinker, potassium persulfate (KPS) and sodium metabisulfite (SMBS) as a type of mixed redox initiators. Selected samples were loaded with model drug chloramphenicol. For the chloramphenicol release, the effect of pH, monomeric compositions, degree of crosslinking were investigated. The release of chloramphenicol was studied for 11 day period in phosphate buffer solutions of different pH 2, 4, and 7.2. The swelling ratio (Rs) was measured for all the hydrogel structures, in three different media (pH=2),
(pH=4) and (pH=7.2), and three different temperatures (37, 45, 50 ) 0 C as function of
time. The results showed that drug release increased by decreasing (MMA) content in the hydrogels

In sample surveys, variance estimate is one of the most commonly used measures for analysing error. This study is the first to introduce variance estimatesfor price changes of commodities from the Consumer Price Index (CPI) for Kurdistan Region (KR) of Iraq. The CPI, which is considered as an indicator for general level of prices, is the most significant economic indicator that enters into decisions about monetary policy settings for any country. The accuracy and reliability of this indicator (CPI) over time relies on the accurate measurements ofprice changes. Meantime, the study provides the first release of CPI for urban consumersof Kurdistan Region of Iraqand then computes the price changes of commodities for 1-month, 2-month, 6-month, and 12-month intervals and the corresponding standard error estimates using the monthly data, which is provided by Kurdistan Region Statistics Office (KRSO),for the period January to December 2009.

This study involves the efficiency evaluation of pomegranate shells extract as natural corrosion inhibitor for C-Steel in 1N HCL at various temperatures (293,323and343) °K using electrochemical technique. The results show that the inhibition efficiency increases with increasing the extract concentration and decreases with increasing temperature. The results of Potentiodynamic polarization curves indicate that the pomegranate shells extract behaves as a mixed type inhibitor. The thermodynamic functions of dissolution and adsorption processes were determined from experimental polarization curves and the interpretation of the results is given. The apparent activation energy, enthalpy , entropy and free energy of the dissolution process were determined and discussed.The Surface analysis (SEM and FT-IR) was also carried out to establish the corrosion inhibitive property of the pomegranate shells extract in 1N HCL. Metallurgical Microscope and FT-IR tests indicated that the pomegranate shells extract had high efficiency on adsorption on C-Steel from through function groups (carbonyl, phenol and amines). The results obtained showed that the pomegranate shells extract could serve as an effective natural inhibitor for the corrosion of C-Steel.
