Investigation of the effect of allo- and xenotransplantation of pancreatic tissue cultures on the hemodynamic indices of 85 patients with diabetes mellitus using ophthalmoscopy, biomicroophthalmoscopy, integral rheography, capillaroscopy and clinical biochemical tests at varying time (from 3 mos to 4 yrs.) showed a gradual improvement of the ophthalmological picture of the fundus of the eye in 58 patients (86%) during the first 9 mos with further stabilization of a process. Lower limb improvement was noted in 18% of the patients, stabilization of a process--in 74%. The improvement of the renal clinico-biochemical indices was noted in 47-67%. Contraindications for beta = culture transplantation were diabetic glomerulosclerosis with stage III chronic renal insufficiency and retinopathy of diabetorenal type.
