Anti-hepatoma monoclonal antibodies HAb8
HAb18 IgG and HAb18 F(ab’)
2
were labelled with[
131
I]according to chloramine T method.The labelling rate andradioactivity were 51% and 9.58×10
4
Bq/mg
respectively.After administration of the[
131
I]-labelled conjugates through mouse tail vein
hepatoma xenografts were clearly im-aged
Localization index was 2.15
3.09
and 6.99 for HAb8
HAb18 IgG and HAb18F(ab’)
2
respectively.A total of 16 hepatoma-bearing nude mice(SMMU-LTNM)were di-vided into 4 groups.When xenografts reached 0.3cm in diameter
the treatment was be-gun by injection of the[
131
I]-conjugates through mouse tail vein.After 2 weeks of treat-ment
obvious inhibitory or killing effects on the xenografts were found.The tu-mor-bearing mice were killed during the period from 14 to 21d after treatment.Xenografts as well as other organs were sampled and viewed under light microscope ac-cording to routine procedure.The vital organs
such as heart
liver
spleen
lung
kidneyand brain showed no pathological lesions.In hepatoma xenografts
some tumor cellmembranes were found
with obscure cytoplasmic structure and increased eosinophilia
representing necrotic alterations.
