[ relative frequency of the epithelial cell abnormalities in the cervicovaginal smears of women referring to Medical Center Of Al-Zahra Hospital Of Isfahan from 1996-2001]

Objective: the goal of this research is to study the relative frequency of different types of epithelial cell abnormalities in cervicovaginal smears

Material and methods: this descriptive-retrospective study was carried out in Al-zahra Hospital of Isfahan University during the period 1996-2001.538 satisfactory cervicovaginal smears by using the Bethesda classifiction system are reviewed

Results: of the 538 cervicovaginal smears, 115[21.37%] were normal. Others were reactive changes: 372 [69.14%], ASCUS: 30 [5.75%], LSIL: 9] [1.97%], HSIL: 3 [0.55%], SCC: 1] [0.18%], benign endometrial cells in post menopausal women: 4[0.74%], AGUS: 1] [0.18%], Endometrial adenocarcinoma: 1] [0.18%] and extrauterine adenocarcinoma: 2] [0.36%]. Endocervical adenocarcinoma is not identifiedin this study

Conclusion: ASCUS results [5.75%] are compatible with universal standards. The carcinoma results differ with other countries. It is estimated that the screening programs in adenocarcinoma are not effective as squamous cell carcinoma

effects of noise exposure on rat's hematologic parameters and red cell indices

Environmental pollution plays a destructive role in the daily life of industrialized communities and due to their negative impact on the society they are always under close investigation. Besides wellknown pollutants substantial, all major international health organizations consider noise pollution as an important health problem. In this study, we have used an animal model to study the effects of noise exposure on is hematological survey [CBC] and red cell indices. Forty male Winstar rats were randomized into two groups of test and control. Animals in the test group were exposed to a 20 dB unmodulated sinusoidal noise with a frequency of 1100 Hz for 120 days, while animals in the control group were kept in normal condition. By the end of the study, a blood sample was taken from each animal in both groups and a complete blood count was performed. In animals in the test group as compared to those in the control; 1] there was significant [p<0.001] increase in the number of red blood cells, white blood cells, hemoglobin, and hematocrit; 2] there was significant [p<0.001] decrease in mean corpuscular volume [MCV], mean cell hemoglobin [MCH], and mean cell hemoglobin concentration [MCHC]. It was then concluded that noise exposure affects blood cells
