the aim of this study was the evaluation of acute genotoxic effect of effluent water of thermo-power plant by means of tradescantia root tips micronucleus test (mn), mitotic index and cell aberrations.   tradescantia , was experimentally treated (for 24 h), with effluent water of thermo-power plant in different dilution ratios (negative control – distilled water; primary untreated effluent wate...

meningiomas are slow-growing neoplasms which recur locally, their morphologic grading is simple but do not always correlate with patient outcome. the aim of present study is to evaluate the status of progesterone receptor (pr) and proliferation marker ki67 in various grades of meningioma in a group of iranian patients. 78 cases of meningioma were selected from the file of a hospital university....

phytohemagglutinin (pha) is a lectin, obtained from the red kidney bean that binds to the membranes of t-cells and stimulates metabolic activity, cell division, etc. the object of this research was the comparison between self made pha (indigenous) and imported commercial one, following conventional and high resolution cell synchronization technique (hrcs) .from each blood sample of healthy indi...

Liver regeneration is known to begin after experimentally induced liver resection. At first 24-48 hours, DNA synthesis reaches the maximum level resection and significantly occur on 10 days. In this study, we was examined of 1st 14th days 
 experiment 21 Wistar albino male rats were used. The randomly divided into three groups. All groups realized midline incision with laparotomy for liver...

PURPOSE High proliferation rate is a hallmark of cancer. The mitotic index is a useful and simple method for analysis of cell proliferation. However, the practical utility of mitotic index as a predictor of prognosis in patients with hepatocellular carcinoma (HCC) has not been determined. Therefore, we examined mitotic index as a prognostic marker in HCC patients. MATERIALS AND METHODS We cou...

Allium cepa bulbs were grown in pure tap water (group I), in seven concentrations of acetaminophen (7.81, 15.62, 31.25, 62.50, 125, 250, 500, and 1000 ppm) in the presence (group II) and absence of myrobalan (fruit of Terminalia chebula) at a fix concentration of 0.10 mg/mL. Parameters of study were mean root length, mitotic index, abnormal mitosis and chromosomal aberrations and morphology of ...

allium cepa bulbs were germinated in pots for three days on treatment area on which 380 kv high voltage power lines are passing. ten bulbs were set up for each treatment area (0 m (meter), 10 m, 25 m, 50 m and 100+ m for control from power lines). triticum baeoticum boiss. subsp. baeoticum seeds were collected at same distance from power lines on planted field. ten seeds from each area were ger...
