The present work involved a study the effect of cobalt(II) complex with formula [CoL(H2O)NO3] .4ETOH where L=Nitro [5-(P-nitro phenyl) -4-phenyl-1,2,4 traizole-3-dithiocarbamato hydrazide] aqua. (4) Ethanol and anti-cancer drug - cyclophosphamide on specific activity of two liver enzymes (GPT,ALP) by utilizing an in vivo system in female mice. On the enzymatic level an inhibition in the activity of GPT was noticed in different body organs such as liver, kidney and lung. The inhibition was noticed in both test and cyclophosphamide drug (cp). Mice were treated with three doses of cyclophosphamide (90,180, 250) ?g/ mouse for three days. The same doses were used for the cobalt (II) complex. The liver shows the highest rate of(GPT) inhibition compared to other organs. The ratio was about 90% at three doses of cobalt (II) complex, this ratio was similar to ratio inhibition of cyclophosphamide at the same doses. On the contrary the enzyme ALP showed high activation in different organs such as liver, kidney and lung in both groups, test and cyclophosphamide drug (cp) at the three doses (90, 180, 250) ?g /mouse. The result showed the highest ratio of activation in the kidney comparable with other organs. The maximum activation of cobalt(II) complex was about 1198% at a concentration 180µg/mouse.There are significant differences(P

The new complexes of copper (II) 1,2 where L 1 in complex (1) was 2-Amino-5-[2-amino-5-(3,4,5-trimethoxy-benzyl)-pyrimidinyl-4-azo]-phenol, while L 2 was 2-[2-Amino-5-(3,4,5trimethoxy-benzyl)-pyrimidinyl-4-azo]-4-bromophenol and aqueous extract of Origanum Vulgare L.plant (after the chemical assay)were studied on the growth on of Rhabdomyo sarcomas(RD)cell line in human by using in vitro system and compared with anticancer drug cisplatin (cis-pt) as a posative control.The cancer cells were treated with different concentration (31.25, 62.5, 125, 250)µg/ml for each of the three treatments and cis-pt after 72 hour exposure time. The cytotoxic activity was tested by inhibition rate as parameter. The results showed significant differences (p<0.05) for each three treatments when the inhibition rates were increased. The inhibition levels was reached to 48.13% , 51.75% and 51.63% respectively at 250µg/ml.There was strong correlation between the three treatments and the different concentrations in comparison with cisplatin.
