Observations for the linear polarization of comet Hyakutake (C/1996B2) are carriedout at three continuumwavebands: 3650Å, 4845Å and 6840Å. These observations were taken on March 13 and March 18, 1996 when the phase angles were 38.1 and 36.9, respectively. These results indicate an increase in the degree of polarizationwith phase angle andwavelength, in general. Present results show that comet H...
The aim of this study was to evaluate the genotoxic effects of a crude extract of khat (Catha edulis, Forsk) leaves in rats. Two groups were fed khat crude extract, 1000 and 2000mg/kg body weight, for 90 days and were compared with a control group. The alkaline (pH>13) version of comet assay was used in this study. However, no previous published work has been undertaken and showed the effect of...
