Abstract
BACKGROUND Burn injury is a major cause of death and disability worldwide. A domestic medication in wound healing, preventing infection and reduction of scar tissue as well as availability is still an important challenge. This study aims to evaluate the efficacy of yolk egg oil in treatment of burn wounds in rats. METHODS A standard 3rd degree burn wound was produced and the animals were divided into three groups according to topical treatment including yolk oil, 1% silver sulfadiazine (SSD) and control. In days 7, 14 and 30,animal's weight, wound size, as well as histopathological findings of skin were evaluated in different groups. RESULTS Average size of wound after 7 days was 3.4, 5.3, and 6.7 cm in yolk oil, SSD and control groups. There were significant differences between yolk oil and the other groups in this aspect. The wound size of yolk egg group was also significantly smaller than other groups in 14th and 30th days. Results of the histological studies indicated significant differences between yolk oil, SSD and control groups on day 30, with mean score of 3.75, 3.5 and 2.8 respectively. The difference between yolk oil and the other groups was significant. CONCLUSION Yolk oil-treated burned animals showed abundant re-epithelialization without tissue scar in comparison with SSD group. Although the egg yolk has many vital nutrients, but its exact mechanism in healing process is unknown. Therefore, further studies evaluating the influence of individual components on burn-healing process is advised.

Abstract
INTRODUCTION In the scope of this study, we had to do a qualitative and quantitative research of the current electrolytes as part of aqueous humour samples taken from patients suffering from cataract. MATERIALS AND METHOD The tests were carried out by X-ray fluorescence and ICP/AES. The detection limit for the electrolytes varied from 0.005 to 0.1 ppm. RESULTS The test results show iron (minimum 0.82ppm; maximum 25.50ppm), copper (0.28ppm; 8.17ppm), brome (5.18 ppm ; 55.82ppm), zinc (0.70ppm ; 9.78ppm ), sodium (1274.83ppm, 5211.67 ppm), potassium (55.52ppm ; 255.02ppm), calcium (26.46 ppm ; 256.81ppm), magnesium (5.77ppm; 70.33ppm). CONCLUSION The data study have enabled us to establish reference value for each electrolyte. Study of the comparative reference values, together with the contents found in the normal aqueous humour, the normal and pathologic crystalline lens, has shown a noticeably low concentration of electrolytes and breakdown of the sodium/potassium pump which ensures ionic exchange between aqueous humour and the crystalline lens.

Abstract
Maternal alcohol abuse is known to produce retardation in brain maturation and brain functions. Using cultured glial cells as a model system to study these effects of alcohol we found an alcohol antagonizing property for manganese (Mn). Mn was added to the alcohol diet (MnCl2 25 mg/l of 20% v/v ethanol) of pregnant rats. Glial cells were cultured during 4 weeks from cortical brain cells of pups born to these mothers. Several biochemical parameters were examined: protein levels, enzymatic markers of glial cell maturation (enolase and glutamine synthetase), superoxide dismutase a scavenger of free radicals produced during alcohol degradation. The results were compared to appropriate controls. A beneficent effect of Mn was observed for the pups weight which was no more significantly different from the control values. Protein levels, enolase and glutamine synthetase activities were increased mainly during the proliferative period when Mn was added to the alcohol diet compared to the only alcohol treated animals. This Mn effect was not found for superoxide dismutase in cultured glial cells but exists in the total brain of the 2 week-old offspring. In the total 2 and 4 week-old brain the alcohol induced decrease of enolase and glutamine synthetase was also antagonized by the Mn supplementation. Our data suggest that Mn may act as a factor overcoming at least partially some aspects of alcohol induced retardation of nerve cell development.

Abstract
We applied the energy-dispersive x-ray fluorescence technique to determination of trace elements in human bronchoalveolar lavage fluids. Our analysis of more than 200 samples allowed us to determine normal reference values, to be used in characterizing occupational exposure. These values are expressed both in nanograms per 1000 cells (of all kinds) and nanograms per 1000 macrophages to correlate lavage efficiency and dust content of the alveoli. The result expressed in milligrams per liter is not sufficient, because some healthy volunteers showed high concentrations of iron but normal values when expressed vs the number of cells. Some examples of abnormal compositions of broncho-alveolar lavages are reported and the fully automated spectrometer developed for clinical and biological investigations is described.

Abstract
We applied energy-dispersive x-ray fluorescence to the determination of abnormally present elements or abnormal concentrations of elements in human broncho-alveolar lavage fluids. The low detection limits and the ability to perform multi-elemental analysis permit one to establish or confirm occupational exposure of workers. We also describe different methods used to check our method and our results. We report examples of abnormal compositions of broncho-alveolar lavages containing W, Ce, La, Nd, I, Fe, or Ni. We discuss the limits of the method for characterizing silicosis or asbestosis.

Abstract
Abstract
We have applied energy dispersive x-ray fluorescence to the analysis of broncho-alveolar lavage fluids, to determine the concentration of several elements simultaneously with manipulation of the sample minimized. A 20-microL sample of a homogenized lavage fluid, to which two internal standards (containing Y and V) have been added, is deposited on a polypropylene film, 4 microns in thickness, and analyzed by x-ray fluorescence. We report the analytical procedure, the detection limits, and the reproducibility. The normal concentration range for trace elements is reported for a selected population. The simplicity and rapidity of the method, and the possibility of automating measurements, make this procedure suitable for screening large numbers of lavage specimens and to establish the diagnosis of some pneumoconioses.

Abstract
Energy-dispersive x-ray fluorescence is applied in the analysis of human serum to determine the concentrations of several elements simultaneously with minimal manipulation of the sample. The analytical procedure has been developed with standard sera, and standardization, detection limits, and reproducibility have been established. A 50-microL sample of diluted serum, to which an internal standard has been added, is deposited on a thin (4-microns thick) polypropylene film and analyzed by x-ray fluorescence. We report the statistical distributions of the concentrations of Fe, Cu, Zn, and Br obtained in the population (103 samples) studied, and report detection limits for the other 22 elements studied. The simplicity of the method, the high throughput, and the possibility of automating the measurements make this procedure suitable for screening large numbers of sera.
