Technetium uptake predicts remission and relapse in Grave's disease patients on antithyroid drugs for at least 1 year in South Indian subjects.

Context: Most of the information on remission related factors in Grave's disease are derived from Western literature. It is likely that there may be additional prognostic factors and differences in the postdrug treatment course of Grave's disease in India.

Aim: To study factors which predict remission/relapse in Grave's disease patients from South India.

Hemodynamic changes during aging associated with cerebral blood flow and impaired cognitive function.

This study investigates the age associated changes in hemorheological properties and cerebral blood flow. Partial correlations indicate that part of the age-dependent decrease in flow velocities can be attributed to a hemorheological decrement resulting in part from enhanced oxidative stress in the aged. A possible link with Alzheimer's pathology is suggested by the augmented hemorheological impairment resulting from in vitro incubation of red cells with amyloids.

Hemostatic variables in Arab diabetics.

Blood coagulation studies showed that patients with non-insulin-dependent diabetes mellitus (NIDDM) had significantly higher fibrinogen, FVIII:C, ristocetin co-factor, FV, FIX, lower ATIII, and PCV than those with insulin-dependent diabetes mellitus (IDDM). Diabetics with IDDM had a significantly higher ATIII, ristocetin co-factor, lower plasminogen and alpa-2-antiplasmin, and more enhanced platelet aggregation responses to ristocetin than age-matched controls. Patients with NIDDM as compared with controls, exhibited higher levels of fibrinogen, ristocetin co-factor, FVIII:C, FIX, and platelet count, but lower plasminogen, alpha-2-antiplasmin and PCV, reduced platelet aggragability to collage, ADP, and ristocetin.
