Abstract

Hypertension is one of the major modifiable risk factors for coronary heart disease, stroke, peripheral vascular disease and renal failure. The aim of treating hypertension is to maximize therapeutic efficacy without untoward side effects. The study population was carried out in emergency department of Razgary and Jumhury hospitals in Hawler. Hypertension was highly prevalent among aged persons between 61-70 years 33(27.5%) while the lowest percentage were recorded in the age group 30-40 years 8(6.6%). Female population showed higher percentage 53.3% than male 46.6%.Duration of hypertension more than five years 80 (66.6%) which was higher than those less than two years 8 (6.6%). Family history of hypertension appeared as strong risk factor of hypertension that recoded 76(63.3%). According to educational level found the hypertension was higher in Illiterate-primary education 55 (45.8%) than Intermediate –secondary school education 38(31.6%) and lowest among highest educational level 27(22.5%). Body mass index (BMI) had effect on percentage of hypertension among overweight patients 62 (51.6%) followed by obesity39 (32.5%)and lowest in patients with normal weight 19(15.8%). Co-morbidity was observed in70(58.3%)among which diabetes mellitus was28(23.3%)followed by cardiovascular disease 19(15.8%) and hypercholesterolemia was11(9.1%) . Types of drug used to treat hypertension show diuretics and angiotensin converting enzyme inhibiter were the most drug used 26(21.6%) and 25(20.8%) respectively followed by combined drug and calcium channel blocker were 19(15.8%),18(15%) respectively then angiotensin receptor blocker17(14.1%)and beta -blocker used in 15(12.5%).

Abstract

Introduction: Anemia in pregnancy is considered one of the major risk factors contributing to maternal deaths in developing countries. The present study was carried out to determine the prevalence of anemia among pregnant woman according the hematological and biochemical parameters in Kirkuk health care centers. Patients and methods: This study involved a total of 132 woman attending primary health care centers in Kirkuk city for the period from 1 st July 2010 to 30 th March 2011 in Iskan and Rahem-Awa region. They were consisted of three groups, Group one (G1) consisted of 87 pregnant women, second Group (G2) consist of 30 non pregnant women and third Group (G3) consisted of 15 w ere not married. They were investigated for hematological tests, Hb, PCV, RBC, WBC, MCV, MCH, MCHC, and biochemical test copper, magnesium, zinc, albumin. Anemia is classified as mild anemia from 10 -10.9g/dl, moderate anemia from 8-8.9g/dl, and severe anemia < 8g/dl. Result: The result showed that there was significant difference in level of Hb, PCV, RBC, MCH, between the pregnant woman and control groups; regarding the difference in trimesters the most influenced parameters were Hb, PCV, RBC, and MCV. The educational state had significant influence on the level of PCV, MCV, and MCH. The pregnancy trimesters had significant effect on albumin level, copper and zinc, while there was significant difference in level of zinc according to education. Conclusion: It was concluded that there was no anemia in this study among pregnant woman although the Hb, PCV, RBC values among pregnant were lower than non pregnant but 37.9% of pregnant women had mild anemia.

Abstract

Introduction:Organophosphate and carbamate insecticides pose major environmental pollution problems and health hazards to people and animals. These insecticides inhibit cholinesterase (ChE) activity in the nervous tissues and neuromuscular junctions. The measurement of blood ChE is a useful tool for monitoring exposure to organophosphate and carbamate insecticides. The purpose of the present study was to use a modified electrometric technique for measuring blood ChE in workers exposed to the organophosphate and carbamate insecticides in Kirkuk, Iraq. Method: A modified electrometric method was used to measure ChE activity in the whole blood of male workers (n = 40) exposed to organophosphate and carbamate insecticides, for a duration of not less than six years. Healthy male volunteers (n =12) not exposed to insecticides served as controls. Following in vitro inhibition of pseudo cholinesterase by quinidine sulfate, true cholinesterase activity was estimated in the blood of the subjects. After in vitro addition of the organophosphate (chlorpyrifos and methidathion, 0.5 and 1 µM) and carbamate (carbaryl, 5 and 10 µM) insecticides to the reaction mixtures, inhibitions of blood ChE were also determined. Results: Mean values of ChE activities (pH/20 min) in the whole blood of healthy non-exposed subjects and insecticide-exposed workers were 1.41and 1.2, respectively. Whole blood ChE activities of the exposed workers was significantly lower than those of healthy individuals. Conclusions: These findings indicate the usefulness of the modified electrometric method for monitoring blood ChE activity in insecticide-exposed workers and there was a significant effect of these Organophosphate and carbamate insecticides on the activity of Ach esterase in workers blood. .

Abstract

The delta modulation technique permits an accurate of an arbitrary reference. Spectrum of the current going through an inductive load shows a very low THD. Moreover, notches are located aroun d the sample frequency multiples, which is of interest for converters without output low-pass filter. In this paper, we demonstrate that the delta modulator structure can be easily implemented when regulating the converter output current going through an inductive load. Then, we propose a mean for computing the load current spectrum using the Laplace and Fourier transforms.

Abstract

In this work, we have measured the concentration of radon gas in eight cement samples from different origins by using long-term measurement of radon decay products with solid state track detectors which alpha particles that emitted from radon gas was detected using (LR115II) nuclear track detector. The obtained results show that, the highest average radon gas concentration in cement samples was found in Iraq cement (Samawa) sample, which was (10.625 Bq/m 3 ) ,while the lowest one was found in (Saudi) sample, and found to be (2.486Bq/m 3 ). The present results show that the radon gas concentration in all cement samples is not below the allowed limit from (ICRP) agency.

Abstract

Hydrazones derived from 4- phenoxybutanoic acid were reprepared and their oxidation potentials in Micellar-Ethanol solution were measured using cyclic voltammetric technique. These compounds were used as photosensitizers in three component system containing methyl viologen (MV 2+ ) and Na2EDTA. Different behaviors of the hydrazones were observed as photosensitizers depending on their oxidation potential values and their stability in irradiation solution. Rate constants of methylviologen reduction by the photochemical active hydrazones were recoded and hydrogen was photoproduced using TiO 2 as catalyst

Abstract

4-Chloro acetyl amino sulphamethaoxazole (A1) was synthesized by the reaction of amino sulphamethaoxazole with chloro acetyl chloride, Then refluxed with ammonium thiocyanate to obtain thiazoldine-4-one (A 2) . (A2) was stirred with formaldehyde and various secondary amines to gain 5 novel compounds Mannich bases(A 3-7 ).and 2,5-Disubstituted thiazolidine-4-one (A 8-11) were synthesized by the reaction of substituted benzyldehyd with Compound (A2) . The structure of the synthesized compounds are confirmed by I.R, 1 H-NMR & 13 C-NMR spectra and Some chemical physical data
