Elemental analysis, magnetic susceptibility and spectral (Ir, Dv-vis and NMR) measurements have been used to characterize the complexes and suggest their structures. Ir data show that the ligand behaves as mononegative tridentate. http://hdl.handle.net/123456789/826 Title: Cytogenetic activities of fusarium spp. metabolites on A. cepa<br/><br/>Authors: Soliman, M.S.A.; Badran, R.A.M.<br/><br/>Abstract: The effect of four mycotoxins on the chromosomal arrangement during mitotic cell division of Allium cepa was examined. Results indicate the presence of certain changes in mitotic stages index (M.S.I) as well as some chromosomal anomalies which reflect toxic activity due to the exposure of the tested bulbs to the four fungal species. F. equiseti gave the highest deviation of chromosomal index from the normal chromosome behaviour followed by F. solani, F. moniliforum and F. culmorum. http://hdl.handle.net/123456789/6680 Title: Biochemical and behavioural responses of common carp cyprinus carpio to sulphuric acid<br/><br/>Authors: AL-Kahem, H.F; AL-Akel, Ali S; Shamsi, M.l.K; Chaudhary, M.A; Ahmad, Z<br/><br/>Abstract: Common carp. CyprinllJ carpio; was exposed to different concentrationof sulphuric acid (H ~SO~). The calculated LC", value was 25 •.•.1/1. The treated fish showed remarkarble behavioural changes. A marked declinein haemoglobin and glycogen content was observed. The physiological/behavioural responses of the fish were directly related to the acid concentrations. http://hdl.handle.net/123456789/6275 Title: Effects of indomethacin of darns and foetuses of C57 BL/6J Mice<br/><br/>Authors: Abu-Tarbosh, F.M.<br/><br/>Abstract: Normal adult inbred C57 BL/6J mice were used to investigate the teratogenic and other possi-ble toxic effects of indomethacin on both dams and their foetuses. The dams have been treated with vari-ous doses of the drug once each day from day 7 to day 12 of pregnancy. The prenatal administration of the drug at 2, 3, 4 or 6 mg/kg body weight has significantly increased foetal mortality rate and decreased the mean number of live foetuses. The highest dose used (6 mg/kg body weight) has also significantly decreased the live foetal body weight. None of the doses used has induced any foetal malformations but the highest doses of the drug (4 and 6 mg/kg body weight) used were toxic on the dams.
