Spectroscopic and chromatographic evidences of NADPH in human placental extract used as wound healer.

An aqueous extract of human placenta, which is used as wound healer, has been investigated in terms of fluorescence properties. When excited at 340 nm, it results in fluorescence emission having maxima around 436 nm, which is fairly specific for nicotinamide adenine dinucleotide, reduced form (NADH) and nicotinamide adenine dinucleotide phosphate, reduced form (NADPH). The excitation spectra, having emission at 440 nm, show patterns comparable to these nucleotides. Thin layer chromatography and reversed-phase (RP) HPLC confirm presence of only NADPH in the extract. The emission and excitation patterns of NADPH purified after HPLC resemble exactly with the reference compound. Its content has been estimated to be 0.018 +/- 0.003 mg/ml based on fluorescence emission with respect to a standard calibration curve (n=6). Biological functionality of NADPH in the extract has been confirmed by glutathione reductase assay (n=5).

Use of placental extract for the treatment of myopic and senile chorio-retinal dystrophies.

After an examination of the literature, the authors evaluate the activity of placenta extract in 34 subjects suffering from chorio-retinal dystrophy of different types (myopic and senile) and of different degrees of anatomo-functional alteration. The parameters used for this study were visual acuity, the luminous sense, the visual field and the electrophysiological activity of the retina. The aqueous solution was administered by intramuscular route at a daily dose of 3 ml (equivalent to 1,80 g of fresh organ) during 20 days; the parameters were tested before and at the end of the treatment. The results obtained during this study show that the parameters were improved, in different degrees, by the administration of the placenta extract. This is clearly demonstrated by the significant improvement in the luminous sense.
