RESUMEN

Background: staphylococci is a resistant bacteria which may exist in normal flora of skin, eye, upper respiratory tract, gastrointestinal tract, urethra and rarely vagina. These species can be the causes of several syndromes such as superficial and deep cutaneous infections, systemic poisoning, and urinary tract infections. In the current survey, we studied the frequency of staphylococcus aureus carriers and compared it between medical and non-medical personnel in Be'saat medical center


Materials and Methods: an analytic cross-sectional study was designed to determine the frequency of nasal cavity and hand carriage of staphylococcus aureus among 253 personnel and compare the index between medical and non-medical staffs. The specimen was provided and cultured in selective media. By bacterial growth and determination of the species using specific diagnostic procedures, results were calculated in both medical and non-medical personnel and compared with chi-square statistical test regarding an alpha level of 0.05 as significant


Results: of total 253 personnel 65 [25.7%] were nasal carriers of staphylococcus aureus which 35 were medical [23% of 153 medical staffs] and 30 were non-medical [30% of 100 non-medical staffs] personnel. On the other hand, from 10 hand carriers of staphylococcus aureus 6 were medical [3.9%] and 4 were non-medical [4%] staffs [p>0.05]


Conclusions: due to our findings, in spite of higher frequency of staphylococcus aureus nasal carriage among medical staffs than non-medical personnel, there is not a significant difference between the prevalence. The same finding was obtained in hand carriage of the germ. So the target group of educating for hygiene improvement to decrease the load of colonies is not only the medical staffs [as the most traditional target] but also non-medical staffs [who are usually out of sight]

RESUMEN

Background: Cyclosporine is an immunosuppressive drug used largely in organ graft medicine with serious effects on liver parenchyma. We experienced combination of cyclosporine and vitamin A for liver damage risk reduction in rats


Materials and Methods: We random allocated 40 rats in 4 study groups and inoculated 1. cyclosporine with olive oil subcutaneously; 2. intramuscular cyclosporine and vitamin A; and 3. subcutaneous absolute olive oil. The 4[th] rat group was not injected and it considered as normal control group. Inoculation was continued for two weeks and rats were kept in standard equal environmental condition. By the end of the injection period they all were dissected and 2 liver tissue samples were studied from each rat using H and E stain and light microscope. Tukey test was used to compare kupfer cells between study groups by considering an alpha level of 0.05 as significant


Results: Hepatocytes disarrangement, congestion and hyperemia of sinusoids, and apoptotic cell enhancement were outcomes of cyclosporine use in rats. There was also blood in kupfer cells and obscure portal space. In comparison with vitamin A addition cyclosporine group showed increasing of kupfer cells [P<0.001]


Conclusion: Adding Vitamin A to cyclosporine regimen can probably results in liver damage risk reduction

RESUMEN

Background: Human sperm heads which present disturbances of choranatin condensation are stained by acidic aniline blue. To determine whether the proportion of unstained heads, i.e with well condensed chromatin, can be considered as an index of sperm quality


Materials and Methods: stady was undertaken in 20 infertile patients with spinal cord injure and 20 infertile patients with non- spinal cord injure. In addition to the usual sperm characteristics, the percentages of unstained heads and of morphologically normal and abnormal forms were concomitantly evaluated


Results: The results obtained in this research show a significant relationship between the mean of sperm volume, concentration, validity and motility


Conclusion: In scipationts and the results taken by previous researchers. In addition the mean of sperm morphology and sperm condensation between the two groups was not significant so we can say that s.ci has no significant effected on condensation of chromatin of sperm
