Catalpol restores LPS-elicited rat microcirculation disorder by regulation of a network of signaling involving inhibition of TLR-4 and SRC.

LPS-induced microvascular hyperpermeability and hemorrhage play a key role in the development of sepsis, the attenuation of which might be an important strategy to prevent sepsis. However, the current clinical therapies have proven to be inefficient in improving the prognosis for patients with sepsis. Catalpol, an iridoid glycoside extracted from the roots of Rehmannia, has been reported to protect against LPS-induced acute lung injury through a Toll-like receptor-4 (TLR-4)-mediated NF-κB signaling pathway.

Kudiezi Injection(®) Alleviates Blood-Brain Barrier Disruption After Ischemia-Reperfusion in Rats.

Objective: This study was designed to examine the effect of KDZ, on the BBB disruption in rat underwent MCAO and reperfusion.

Methods: Male Sprague-Dawley rats (260-280 g) were subjected to 60 minutes MCAO followed by reperfusion. KDZ (4 mL/kg) was administrated before ischemia.

Analysis on correlation of white matter lesion and lacunar infarction with vascular cognitive impairment.

Objective: To investigate the correlation of white matter lesion (WML) and lacunar infarction (LI) with vascular cognitive impairment. To investigate the correlation of cognitive changes of vascular dementia (VD) patients with lacunar infarction (LI) and white matter lesion (WML).

Methods: The clinical data of 60 cases of VD patients were evaluated and analyzed by combining with imageological findings and cognitive function assessment.

Ginsenoside Rb1 ameliorates lipopolysaccharide-induced albumin leakage from rat mesenteric venules by intervening in both trans- and paracellular pathway.

Lipopolysaccharide (LPS) is one of the common pathogens that causes mesentery hyperpermeability- and intestinal edema-related diseases. This study evaluated whether ginsenoside Rb1 (Rb1), an ingredient of a Chinese medicine Panax ginseng, has beneficial effects on mesentery microvascular hyperpermeability induced by LPS and the underlying mechanisms. Male Wistar rats were continuously infused with LPS (5 mg · kg(-1) · h(-1)) via the left jugular vein for 90 min.
