title: [Restoration of immune functions in T-cell depressed spontaneously hypertensive rats (SHR) by injection of neurotropin (author's transl)].
abstract: A strain of spontaneously hypertensive rats (SHR) showed a progressive decline in T-cell functions with aging. In order to restore the depressed immune functions, the effect of immunopotentiators such as Neurotropin, PS-K or thymus extract on immune responses of SHR was studied. The results presented here demonstrated that injection of Neurotropin completely restored the T-cell functions in SHR as detected by a rosette forming test, a plaque forming assay and blastogenesis. Administration of thymus extract also restored the immune functions except helper T-cell activity. However, administration of PS-K increased only numbers of rosetting cells in the thymus of SHR. Biological significance of Neurotropin as immunopotentiators was discussed.
