Resumen:
Physiological parameters on hepatic and renal functionality and biodistribution, accumulation and elimination, in different organs of the 5, 10, 15, 20-tetra (4-methoxyphenyl) porphyrin (TMP) were determined in Wistar rats. The transport of TMP by LDL and HDL lipoproteins was also investigated. The photosensitizer is accumulated in the spleen, where its concentration is significantly increased 21 days post-injection; it also accumulates in the liver and in less proportion, in the duodena, and poorly in brain and muscle. The urine and serum biochemical parameters reached normal values both, in control and treated groups. The glomerular filtrate rates was not affected by the TMP treatment in any of the studied times. These results would indicate that the sensitizer does not modify the renal glomerular function. TMP is mainly eliminated from the organism via the bile-gut pathway. Considering the total amount of porphyrin bound to both lipoproteins (LDL and HDL) in comparison with the total value of the TMP in serum, it can be inferred that a large amount of the agent is transported by lipoproteins in the plasma. This study proves information about the behavior of TMP in vivo under dark conditions. The results can be used to desing photodynamic treatments using this porphyrin model as sensitizer.
