Hemorheologic effects of alpha-1-acid glycoprotein (AGP) were studied in experiment on 76 noninbred white male rats. AGP was administered i.p. to intact rats twice in a total dose of 300 mg/kg. The effects were evaluated 72 hours after the first injection. It was found that AGP accelerated platelet and erythrocyte aggregation, platelet-erythrocyte cooperation, enhanced adhesion of erythrocytes and agranulocytes to endothelium. On the contrary, adhesion of granulocytes and platelets to endothelium was diminished. Acceleration of platelet aggregation was mediated by stimulation of free radical processes in the cells. Thus, AGP produces anticoagulation action on blood theology.

Purpose/background: Clozapine and norclozapine are highly protein bound. Currently, clozapine is increasingly prescribed once daily (QD). Higher (once daily) doses may theoretically lead to saturation of protein binding of (nor)clozapine, resulting in increased unbound fractions.

While diagnostic criteria have been established and validated for most neurodegenerative diseases, the considerable overlap between individual nosological entities remains a significant diagnostic challenge. Increasing evidence suggests that neurodegeneration is often initiated by inflammation within the central nervous system. The identification of inflammation could serve as a first signal of the pathophysiological process.

Introduction: Multiple Sclerosis (MS) is a complex neurodegenerative disease marked by recurring inflammatory episodes, demyelination, axonal damage, and subsequent loss of function. MS presents a wide range of clinical courses, with the progressive forms leading to irreversible neurological disability. Cortical demyelinating lesions are central to the pathology of these progressive forms, gaining critical importance in recent decades due to their strong correlation with physical disability and cognitive decline.
