A study was made of the effect of endovascular laser irradiation of the blood with a He-Ne laser on blood rheological properties, tissue microcirculation and leukocyte function in 28 patients suffering from diabetes mellitus with diabetic angiopathies. A course of endovascular laser irradiation of the blood resulted in the improvement of a clinical course of angiopathies, indices of biomicroscopy of the eye conjunctiva as well as capillaroscopy and thermogenic activity of the limbs. Blood viscosity was significantly decreased; noticeable stimulation of leukocyte beta-galactosidase from 16.4 +/- 3.4 up to 26.8 +/- 4.4 nmol/h was observed. A conclusion has been made that laser therapy leads to significantly improved tissue microcirculation and prevents the development of pathological vascular changes.

Clinical and biochemical findings in two siblings (24-year-old sister and 20-year-old brother), born to consanguineous parents, are described. Both showed progressive generalized myoclonus, macular cherry-red spots, moderate cerebellar ataxia, coarse facies, vertebral deformities, vacuolation of peripheral lymphocytes, bone marrow cells and epithelial cells of conjunctiva, but had normal intelligence. The excretion of sialyloligosaccharides in the urine of both was 3-5 times larger than in the controls. The activities of alpha-neuraminidase and beta-galactosidase in leukocytes and cultured skin fibroblasts were reduced. The clinical and biochemical findings were those of the newly described condition, sialidosis type 2. Review of all Japanese cases considered as sialidosis type 2 showed that the most characteristic clinical features as distinct from type 1, were coarse facies and bone deformities, especially of vertebral bodies.

The spread of herpes simplex virus type 1 (HSV-1) during primary ocular infection and after reactivation of latent infection in the trigeminal ganglion (TG) was examined in the mouse using a genetically modified virus containing the lacZ reporter gene under the control of the immediate-early 110 promoter. Whole tissue mounts of the eye and lids, their sensory nerves, and TG with the attached dorsal root entry zone (DRE) into the central nervous system (CNS) were stained for beta-galactosidase. Sixteen hours after inoculation of the cornea by scarification, staining was found in the scarified epithelium of the cornea and in the unscarified conjunctiva. By 24 h, staining was also seen in a few TG neurons and by 96 h their number had greatly increased and their distribution was more widespread. Stained cells (identified as Schwann cells by their staining for glial fibrillary acidic protein [GFAP] or S-100) in the TG were first seen close to stained neurons at 40 h, and by 48 h lines of such cells extended partway toward the periphery and toward the DRE. By 72 h, these lines had reached the periphery and the DRE where the adjacent CNS was also stained. In the cornea, stained cells with the morphology and arrangement of Schwann cells were seen from 40 to 120 h. After reactivation of latent infection, 10 of 22 samples had positively stained neurons. In eight samples, corneal and lid epithelial cells were stained. No stained Schwann cells were seen in the TG; however, branched networks of such cells were present in the cornea and the lids. This detailed sequential analysis has provided new information on the involvement of Schwann cells in the pathogenesis of primary and recurrent HSV-1 disease in the TG and the cornea.
