Abstract
  The effect of dehydroepiandrosterone (DHEA) on the activity and isoenzyme patterns of liver glucose 6- phosphate dehydrogenase (G6PD) was investigated in rats during different stages of growth. G6PD activity of mature rats was less than those of the immature (43%) and newborn (35%) animals. DHEA at ...  Read More

3. THE RELATIONSHIP BETWEEN ALUMINIUM TOXICITY AND IRON METABOLISM IN RATS

Abstract
  Vanadium (III) gives a greenish- yellow complex with anthranilic acid in presence of pyridine. The complex is extractable with chloroform and is used for photometric determination of vanadium by measuring the absorbance at 390 nm against a reagent blank. Beer's Law holds good in the range of 1-20 ...  Read More

6. PREPARATION AND CHARACTERIZATION OF Mn (III) COMPLEXES
Volume 1, Issue 5 , Autumn 1990

Abstract
  We have prepared and characterized a few Mn (III) complexes by using a few bidentate and tridentate ligands. Spectra of the manganese (III) ion in a variety of molecular environments are reported. On the basis of solution spectra, some of these complexes seem to be typically distorted  Read More

7. PHOTOCHEMICAL DECOMPOSITION OF 3-CHLORO-CROTON ALDEHYDE TOSYLHYDRAZONE SODIUM SALT
Volume 1, Issue 5 , Autumn 1990

Abstract
  The low temperature photochemical decomposition of 3- chloro-croton aldehyde tosylhydrazone sodium salt in tetrahydrofuran results in the formation of 3- chloro- 3- methyl cyclopropene and 5- chloro- 5- methyl- pyrazolenine respectively. In the presence of moisture, the photohydrated compound 3 was ...  Read More

9. ATTEMPTED SYNTHESIS OF 5' - DEOXY - 5' - PHOSPHONO - ISOCYTIDINE SYNTHESIS OF PHOSPHONIC ACID DERIVATIVES OF ACYCLO - NUCLEOSIDES. PREPARATION OF 1- ?- D- ARABINOFURANOSYL PYRIMIDINES
Volume 1, Issue 5 , Autumn 1990

Abstract
  The synthesis of 5' - deoxynucleoside 5' - phosphonates which contains a 5' - CP bond in place of the 5' -COP bond of the naturally occuring nucleotides is described. The preparation of phosphonate derivatives of acyclo - nucleosides and a simple method for the conversion of 1-? -D-ribofuranosyl pyrimidines ...  Read More
