The improvement of spatial memory deficits in APP/V717I transgenic mice by chronic anti-stroke herb treatment
In China, herbal medicine has an extensive history for the treatment of cerebrovascular diseases. Clinical studies have shown that stroke patients are more likely to experience significant memory decline in comparison to their healthy counterparts. Cognition is improved in stroke patients treated with herbal medicine active components, Geniposide (GP) and Geniposide Rg1 (GRg1) (together, called TLJN). However, the effect of TLJN in Alzheimer disease remains unknown. Therefore, we investigated the behavioral effect of TLJN in male and female APP/V717I transgenic (Tg) mice. We conducted two different treatment strategies: (1...

Xiaoxuming Decoction Regulates Vascular Function by Modulating G Protein-Coupled Receptors: A Molecular Docking Study
In this study, XXMD was found to induce relaxation of the basilar artery rings of rats precontracted by 5-hydroxytryptamine (5-HT) in vitro, in a dose-dependent manner. The modulation of vascular tone and the process of cerebral ischemia are mediated via the interactions between G protein-coupled receptors (GPCRs) and their ligands, including 5-HT, angiotensin II (Ang II), and urotensin II (UII). Thus, the potential synergistic effects of the different components of XXMD on the regulation of vasoconstriction and vasodilation were further investigated by molecular docking based on network pharmacology. We constructed and an...

< b > < i > Panax notoginseng < /i > < /b > Saponins Ameliorate Leukocyte Adherence and Cerebrovascular Endothelial Barrier Breakdown upon Ischemia-Reperfusion in Mice
Panax notoginseng saponins (PNS) are known as clinical anti-stroke herbal medicines. The aim of this study is to describe the impact of PNS on ischemia-reperfusion-induced cerebral microvasculature barrier dysfunction which has not been investigated yet. Mice were subjected to transient middle cerebral artery occlusion and PNS were administrated to mice 3 days before and 2 days after surgery. Leukocyte adhesion, albumin leakage, tight junctions and other parameters in the cortex were measured. The PNS 45 mg/kg intervention alleviated leukocyte adhesion, inhibited endothelial barrier alterations evidenced by reduced albumin...

Preventive and Therapeutic Effect of Ganoderma (Lingzhi) on Brain Injury.
Authors: Quan Y, Ma A, Yang B Abstract Neurological dysfunction and death are common events leading to acute and chronic neurodegenerative diseases. Neurodegenerative disorders such as Alzheimer's and Parkinson's disease account for a significant and increasing proportion of morbidity and mortality in the developed world. Ganoderma lucidum (G. lucidum, Lingzhi), one of highly nutritious and significantly effective medicinal herbs, has been used for clinical applications for thousands of years. Several researches have shown that it has a wide range of brain damage protection, such as amelioration of Alzheimer's dise...

Emodin and Its Role in Chronic Diseases.
Authors: Monisha BA, Kumar N, Tiku AB Abstract Diseases, such as heart disease, stroke, cancer, respiratory diseases, and diabetes, are by far the leading cause of mortality in the world, representing 60 % of all deaths. Although substantial medical advances have been made and many therapeutic approaches proposed yet traditional medicine and medicinal plants find an important place in therapy. They have been providing invaluable solutions to the various health problems. Emodin (1,3,8-trihydroxy-6-methylanthraquinone) is a natural anthraquinone derivative found in various Chinese medicinal herbs. Traditionally, it ...

Tetramethyl Pyrazine Protects Hippocampal Neurons Against Anoxia/Reoxygenation Injury Through Inhibiting Apoptosis Mediated by JNK/MARK Signal Pathway.
CONCLUSIONS TMP may produce a protective effect in anoxia/reoxygenation-induced primary hippocampal neuronal injury by inhibiting the apoptosis of the hippocampal neurons; the possible mechanism may be inhibition of the JNK signal pathway. PMID: 28009855 [PubMed - in process]

Influences of Corydalis decumbens on the Activities of CYP450 Enzymes in Rats with a Cocktail Approach.
Abstract Corydalis decumbens, a Traditional Chinese Medicine, has been widely used for the alternative and/or complementary therapy of hypertension, arrhythmias rheumatoid arthritis, sciatica, stroke, hemiplegia, paraplegia, and vascular embolism. The aim of this study was to determinate the potential effects of Corydalis decumbens on the five cytochrome P450 (CYP) enzyme activities (CYP1A2, CYP3A4, CYP2C9, CYP2C19, and CYP2D6) by cocktail approach. To evaluate whether concurrent use of Corydalis decumbens interferes with the effect of several prescription drugs, saline (control group) or Corydalis decumbens (XTW ...
