An evaluation of the hemorheologic parameters and an ultrasonographic study of the extracranial carotid tract were performed on 48 patients, age range: sixty to seventy-five years, affected by acute stroke, 23 of whom had hypertension, while 27 were smokers. None of them was suffering from hyperlipidemia, diabetes mellitus, or symptomatic coronary heart or peripheral artery disease. The echotomographic analysis, using B-mode real-time echotomography revealed atherosclerotic lesions in 26 patients. The hemorheologic pattern (hematocrit, fibrinogen, whole blood filterability, whole blood and plasma viscosity) was determined in all the patients three months after the clinical event. Statistical analysis of the results indicates a possible link between atherosclerotic lesions of the extracranial carotid tract and age, fibrinogen levels, and whole blood filterability.

Canine monocytic ehrlichiosis (CME) is an infectious disease that causes hematological changes in dogs. This study investigated the correlations between hematological and hemorheological parameters, serum proteins, and triglycerides in dogs with CME. Fifty-nine blood and/or bone marrow samples were collected from dogs with or without clinical signs of CME.

Background: SARS-CoV-2 infection adversely affects rheological parameters, particularly red blood cell (RBC) aggregation and deformability, but whether these changes persist in patients suffering from Long-COVID (LC) and whether these changes are related to RBC morphology remain unknown.
Methods: Venous blood was collected from = 30 diagnosed LC patients and = 30 non-LC controls and RBC deformability, RBC aggregation, and hematological parameters were measured. In addition, RBCs were examined microscopically for morphological abnormalities.

Ethnopharmacological Relevance: Unhealthy dietary patterns and lifestyle changes have been linked to increased blood viscosity, which is recognized as an important pathogenic factor in cardiovascular and cerebrovascular diseases. The underlying mechanism may involve chronic inflammation resulting from intestinal barrier disruption induced by unhealthy diets. The rhizome of Atractylodes macrocephala Koidz.

Objective: To investigate the effect of edible bird's nest (EBN) on tumor growth, hemorheology and immune function of mice with transplanted uterine myomas.
Methods: A subcutaneous tumor model of human uterus myoma was established in mice, and the mice were randomly divided into a model group, EBN group, estradiol receptor (ER) group and ER+EBN group. Body weight and tumor volume were measured at 2 weeks, 4 weeks and 8 weeks after the uterus myoma transplantation.
Microbiome-metabolome analysis insight into the effects of high-salt diet on hemorheological functions in SD rats.

The present study examined the effect of two dietary regimens with elevated salt concentrations (4% and 8% salt) on hemorheological functions of SD rats, and explored the underlying mechanisms mainly through microbiome-metabolome analysis. An 8% HSD substantially altered the hemorheological parameters, and compromised intestinal barrier integrity and reduced the short-chain fatty acid levels. The microbiome-metabolome analysis revealed that 49 genus-specific microorganisms and 156 metabolites showed a consistent trend after exposure to both 4% and 8% HSDs.
