For this reason, using normal adult human whole blood haemolysates, it was investigated the effects in vitro of glucose and insulin on normal erythrocytic ALA-D.

The basal levels of the key enzymes involved in heme synthesis, ALA-S and ALA-dehydratase (ALA-D), were decreased about 36% and 54%, respectively, 44-46 days after diabetes induction.

The activity of benzo(a)pyrene hydroxylase in diabetic rats was also increased in proportion to the microsomal content of cytochrome P-450.

However, a similar stimulatory response in ALA-S activity to CoCl2 administration was observed only in control or insulin-treated diabetic rats.

In previous studies, it has been demonstrated that both d delta d-aminolevulic acid dehydratase (ALA-D) and porphobilinogen deaminase (PBG-D), enzymes of the heme pathway, are inhibited by high concentrations of glucose in vitro in crude preparations of erythrocytes.

The activities of erythrocytic ALA-D and PBG-D were measured.

|
ALA-D and PBG-D activities were diminished in diabetic patients (40% and 20% respectively), while rhodanese was only slightly increased (Fig. 1).
|

|
ALA-D activity was subnormal in a 92% of the complete diabetic population, while PBG-D activity was less than normal in a 79% of the same population.

AIA induced hepatic delta-aminolevulinic acid synthetase (ALA-S) activity in control animals but was ineffective in the diabetic group. alpha-Tocopherol did not modify ALA-S activity in either group. delta-Aminolevulinic acid dehydratase (ALA-D) and deaminase activities were significantly diminished both in liver and blood of diabetic animals. alpha-Tocopherol prevented inhibition of ALA-D, deaminase and blood rhodanese activities in diabetic animals but alpha-tocopherol by itself did not affect the basal levels of the enzymes studied.

Erythrocytic aminolevulinate dehydratase activity was reduced in both insulin dependent and non-insulin dependent diabetic patients as compared to their controls (p < 0.001).

In insulin-dependent diabetes mellitus, reduction of enzyme activity was related to the glycosilated hemoglobin concentration (p < 0.05) and in non-insulin dependent diabetes mellitus to the glycemia (p < 0.01).

Finally, the inhibition of catalase, delta aminolevulinic acid dehydratase (eth-ALA-D) and isoforms of lactate dehydrogenase (LDH) accompanied by hyperglycemia were prevented by DPDS in all tissues examined.
