Abstract

Metals are essential to the human body but can be harmful to health when it exceeds permissible limits. Different sorts of cigarettes were chosen from the markets in Iraq to conduct the tests of the elements in these species. The chose samples were tested using EDX instrument. Results demonstrated the presence of the proportions of dangerous elements such as (Sb, Ni, Zn, P, Pb, Cd, Ca, Si, S, Cr, Mg, Na, As, Al, Cl, and Sn), which greatly affect the health of the smoker and its negative effects to the environment. The genuine risk is the result of accumulate these elements in the body of the smoker's lungs, liver, blood or brain and its effects are chronic and more dangerous and threatens the life of the person in the future. A special absorption system was used to absorb tobacco smoke for the tested samples by deionized water. The remaining ash collected for acid digestion and prepared to atomic absorption analyses.

Abstract

Background: Environmental chemicals are thought to adversely affect human reproductive function.
Objective : To estimate the concentration of cadmium(Cd) , lead ( Pb ) and Zinc ( Zn ) in serum and seminal plasma among infertile men .
Methods: A sample of 70 infertile men was investigated. The relationship of trace elements concentration in serum and seminal plasma was studied in relation to sperm density, motility and sperm count.
Results: Except for Zinc the concentration of (Pb) and (Cd) were generally higher in serum than in seminal plasma. The mean concentration of (Zn) in seminal plasma was more than 25 times higher than in serum There were no statistical significant differences observed in the serum and seminal plasma levels of trace elements among the normospermic , oligospermic and azoospermic.
Conclusion: It seems that no significant relationship between these trace elements and the clinical classification of the infertile men was noted. Without considering environmental conditions of life and work, way of nutrition smoking and other possible factors, this study does not present great value.
Key words: Trace elements, infertility, seminal plasma

Abstract

Copper (Cu) Zinc (Zn) and Magnesium (Mg) in serum, RBC, urine and dialyzate fluids were studied in 39 patients, who have been undergoing chronic haemodialysis treatment. They were divided in to polyuric , oliguric and anuric depending on their urinary output. Elevated serum and RBC Mg was observed before dialysis, while decreased serum and RBC level was noticed except serum Mg of polyuric patients. Before dialysis elevated serum and RBC Zn were observed. While after dialysis these parameters were increased. Normal RBC Cu value before dialysis was observed. While low serum Cu was noticed. After dialysis serum Cu showed raised value, while RBC level decreased in oliguric and increased in polyuric patients. Zn / Cu ratio found to be high in those patients. All these results were discussed in relation to urine content and also to the dialyzate fluid.

Abstract

The effective stress method is developed to predict the axial capacity of piles in clay. This method is based on the principle that, at failure, the available shear resistance at the pile soil interface is related to the mean normal effective stress at the pile face and the effective stress friction angle for the soil sliding on the pile material.In this paper, the coupled non-linear finite element method is used to analyze some pile-soil interaction problems. This computer program ( CRISP ) is used for this task. Eight- node isoparametric elements were used for displacements while four- node elements are used for pore pressure. Interface elements are used to simulate the interaction between the pile and the soil. The soil is assumed to follow different models, linear elastic and modified Cam-clay model. A comparison is made between the measured and predicted settlements and excess pore water pressures and good convergence was obtained in which the proposed technique used in this paper, in which the measured excess pore water pressures are considered as initial pore pressures in the computer program ( CRISP ). No load was applied on the pile. The dissipation of excess pore water was studied through carrying out consolidation analysis.

Abstract

The underained stability of cohesive slopes (Φu=0) subjected loads is studied in this paper. Problems of this kind involved in structures rapidly built near the crest of cohesive slopes and heavy equipment (e.g. draglines, buldozers and railways) move on slop. Using the non-linear finite element method, the effects of loads and uniformly distributed loads are studied and the distribution of stresses under these loads is examined. The value of Pcr (critical line load) required equating the driving and resisting for a unit length of the slope was computed using the computer program. The process was repeated until a minimum Pcr was obtained.

Abstract

Background: Trace elements like iron, zinc, magnesium, cobalt and manganese are some of these elements involved in antioxidant defense mechanism. Many authors observed direct association between trace elements deficiency and the cancer mortality. The study was conducted to measure levels of Zinc (Zn), Copper (Cu), Iron (Fe), Manganese (Mn), Cobalt (Co), Nickel (Ni), Chromium (Cr), Cadmium (Cd), and Magnesium (Mg) in saliva of 50 patients with histologically proved squamous cell carcinoma.Patient and Method: Unstimulated (resting) saliva was collected from oral cancer patients one day before surgical excision of the tumor and one day after surgery using plastic polyethylene tubes. The collected saliva was cold centrifuged at 2500 rpm for 10 minutes at 0-5°C.The centrifuged supernatants were stored frozen at (-20°C) until time of analysis using Atomic Absorption Spectrophotometer.Results: Saliva levels of Zn, Mn, Co and Ni were significantly higher in preoperative saliva of oral cancer patients when compared to the normal control. On the other hand, a highly significant reduction in the levels of Cu, Fe and Mg was observed in preoperative saliva of oral cancer patients. However, no significant changes were seen in saliva trace element levels when preoperative values were compared with postoperative values of same patients.Conclusion: Saliva may be employed alone for trace elements measurements or it can be used supplementary to serum test for confirmation of any finding. However, saliva has the advantage of easy collection without trauma to the patients.
