Now a day’s many types of research are carried out on drug delivery systems for early diagnosis and precise treatment with the primary aim delivering maximum therapeutic action, fewer side effects, fast onset action. Magnetic can fulfil this entire requirement. system is defined as to targeted tissue help magnet which may overcome problems arises due conventional such reticuloendothelial cleara...

This report deals with the relationship between liver L-Alanine: 2-oxoglutarate aminotransferaes ( EC 2. 6. 1. 2) activity and RES function. In fasted rats, decrease in .d4-3-ketost eroid hydrogenase ( EC 1. 3. 1. 3 and 1. 3. 1. 4) and phagocytic activity and increase in alanine aminotransferase activity wer e noted. On the other hand, increase in Ll4-3-ketost eroid hydrogenase and phagocytic a...

The inhibitory effect of octreotide on the growth of liver tumour is probably mediated (at least in part) by stimulation of the hepatic reticuloendothelial system (RES) activity. This study therefore investigated the effect of octreotide on the hepatic and splenic RES (assessed by the uptake of technetium 99m labelled albumin colloid, 99mTc-AC) in normal and tumour bearing rats and in animals t...

SUMMARY The clearance of colloidal carbon from the blood stream of rats bearing methylcholanthrene-induced sarcomas has been studied. Growth of both primary and isotransplanted tumors greatly enhances the clearance of carbon. This effect is greater with increasing tumor size. The uptake of radioactive colloidal gold has been studied following intravenous injection. The final distribution of col...
