[Evaluasion and comparison of washed RBCs by closed and open systems]

Leukocyte filters are effective for WBC reduction but they cannot inhibit passing plasma proteins and as a result repeated protein entry may produce allergic transfusion reactions. To deal with this problem, washed RBC method is used. The traditional wash method is an open system through which waste products are carried away in sewers with the risk of environmental pollution. Newly introduced approach for washed RBCs consists of a closed system whereby waste products enter into a bag. In this study, the two methods were compared. The Two open and close wash methods were compared in terms of health system, leukoreduction, risk of transmission of infection and quality control. In each method, 100 bags were washed, coded and then transmitted to different units of blood culture, flowcytometry as well as quality control. The data were collected and analyzed by SPSS14. 200 bags [100 for each method] were studied. Microbiologically, there were no positive results for any of the methods. In quality control also there was not any significant difference in the two methods. In flowcytometry, we didn.t observe any significant correlation in leukocyte count in the two methods before washing [p=0.072], however.there was correlation between them after washing [p<0.0001], demonstrating that the new method was better for leukoreduction. The new washing system method was a superior way because it involves a close system where waste products are discharged into a side bag and disposed as hospital waste. Meanwhile, this approach is more convenient for leukoreduction. In our country, since we still need a washing system for some transfusions, this method is deemed to be a decent and practical one because it impedes environmental pollution

[Related factors with intervals between pregnancies in women who referred to health center of Boushehr city in 2005]

Short intervals between pregnancies will be dangerous and will have some undesirable results like low birth weight, small for gestational age, still birth and neonatal death for the child and death danger, third trimester bleeding, premature rupture of membrane, endometritis and anemia for the mothers. This matter caused many countries specially Iran to accept proper intervening strategies between births. Therefore, present study has been done with the aim to determine related causes with pregnancy intervals in women at Boushehr city. This is a descriptive analytical study. Samples were women who had more than one child and referred to health centers of Boushehr city in 2005. Cluster sampling consisting of 311 samples was carried out. There were six clusters each of 50 samples selected from six centers. To collect data' a questionnaire including 26 demographic variable and questions like parent's educational level and accupation, marriage age of mother, age of mother at first pregnancy, number of children, etc was used. The interval of last two deliveries of 20[6.5%], 25 [8.0%], 41 [13.2%] and 225 [72.3%] women was less than one year, one to two years, two to three years and more than three years respectively. Among effective factors on pregnancy intervals, job, age at the first pregnancy and age at the time of last delivery of mother showed significant relation with their pregnancy intervals. Considering the risks of short interval pregnancies and their effective factors, suitable planning by authorities to provide educational program is suggested
