  1. 01HumanNon-randomized trialEfficacy outcome

    In diabetic patients with retinopathy, intranasal deltalycyn (DSIP) shortened the restoration time of visual evoked potentials after photostress to 95.1 s, against 137.2 s in retinopathy patients without treatment.

    In plain wordsIn diabetic patients with retinopathy, deltalycyn restored eye responses after bright light faster than in patients with retinopathy who had no treatment.

    Summary · context
    The VEP characteristics restored to the initial level in 73.5 +/- 3.3 s from the photo stress moment in the control group; while in diabetic patients with retinopathy this index was 137.2 +/- 11.3 s.
    Summary · context
    Delta- sleep inducing peptide ("Deltalycyn", "Biopharma", Russia Federation) was intranasally delivered in 30 min before photostress.

Studies that did not test the peptide alone1

In this study, Delta sleep-inducing peptide (DSIP) was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Delta sleep-inducing peptide (DSIP).

    In diabetic patients with retinopathy, deltalycyn combined with cerebellar transcranial magnetic stimulation shortened the restoration time of visual evoked potentials to 82.5 s, against 137.2 s without treatment.

    In plain wordsIn diabetic patients with retinopathy, deltalycyn plus magnetic stimulation of the cerebellum restored eye responses after bright light faster than no treatment.
