, a renowned medicinal plant with a rich history in traditional medicine, has gained attention for its potential therapeutic applications. However, the leaves of this plant have been largely overlooked and discarded due to limited knowledge of their biological activity and chemical composition. To bridge this gap, a comprehensive study was conducted to explore the therapeutic potential of the 70% ethanol extract derived from leaves (LAE) for the treatment of cardiovascular disease (CVD).

To develop and use leaves as a resource, we evaluated its potential as a cardiovascular-protective agent. Herein, we investigated the effects and potential mechanisms of leaves extract on lipopolysaccharide (LPS)-induced inflammatory responses in human umbilical vein endothelial cells.

In this study, the effect of MC on lipopolysaccharide (LPS) and recombinant interferon-gamma (rIFN-gamma)-induced production of nitric oxide (NO) and tumor necrosis factor (TNF)-alpha were examined using mouse peritoneal macrophages. MC inhibited the LPS/rIFN-gamma-induced expression of inducible nitric oxide synthase (iNOS) and TNF-alpha release.

The anti-ischemic effects of AF on ischemia-induced isolated rat heart were investigated through analyses of changes in perfusion pressure, aortic flow, coronary flow, and cardiac output. The subjects in this study were divided into two groups: an ischemia-induced group without any treatment, and an ischemia-induced group with AF treatment.

The anti-ischemic effects of NS on ischemia-induced isolated rat heart were investigated through analyses of changes in blood pressure, aortic flow, coronary flow, and cardiac output. The subjects in this study were divided into two groups: a control, untreated ischemia-induced group, and an ischemia-induced group treated with NS.

Melanin forms through a series of oxidative reactions involving the amino acid tyrosine in the presence of the enzyme tyrosinase. Tyrosinase catalyses three different reactions in the biosynthetic pathway of melanin in melanocytes: the hydroxylation of tyrosine to l-DOPA and the oxidation of l-DOPA to dopaquinone; furthermore, in humans, dopaquinone is converted by a series of complex reactions to melanin.

In the water maze test, the animals were trained to find a platform in a fixed position for 6 d and then received a 60-s probe trial in which the platform was removed from the pool on the 7th day. Ibotenic lesion of the MS showed the impaired performance in the Morris water maze test and severe cell losses in the MS, as indicated by decreased choline acetyltransferase-immunoreactivity in the medial septum.

In this study, its anti-depression effects in rats were investigated by comparing the test results of those treated with Nelumbinis Semen to those treated with other herbal anti-depressants, including Rehmanniae Radix Preparat, Corni Fructus, Lycii Fructus, Pinelliae Rhizoma and Hypericum Perforatum. In order to induce depression-like symptoms, the animals were placed under chronic mild stress in the form of overnight illumination for 2 consecutive days.

The results demonstrated that Th2 cells were dramatically underpopulated in the Th2-driven condition triggered by SCRT treatment, while the Th1 cells were not altered in the Th1-skewed condition. Furthermore, under Th2-skewed conditions the levels of interleukin-4 were considerably decreased with SCRT treatment.
