Mechanism of the Inhibitory Effect of Antiinflammatory Baicalin on Airway Reconstruction in COPD Rats
Research Paper Mechanism of the Inhibitory Effect of Antiinflammatory Baicalin on Airway Reconstruction in COPD Rats J. QIU, W. GONG AND J. DONG* Department of Integrative Medicine, Huashan Hospital, Fudan University, 12 Middle Wulumiqi Road, Shanghai, China Qiu et al.: Mechanism of baicalin in inhibiting airway reconstruction in COPD rats The mechanism of baicalin in airway reconstruction in rats with chronic obstructive pulmonary disease was investigated. The chronic obstructive pulmonary disease models were established in rats through smoke inhalation and instilling lipopolysaccharide. The rats were then divided into the control group and the experimental group, a blank group was used as a reference point of the experiment. Rats in the experiment group received baicalin either at a high dose (80 mg/kg/d, H1) or at a low dose (25 mg/kg/d, H2) to analyse the airway reconstruction functions and antiinflammatory effects of baicalin. During the experiment, the general conditions of the rats were compared. After the experiment, lung tissues of the rats were obtained for Hematoxylin-Eosin staining, and the pathological changes were observed. In addition, the bronchial walls were measured and analysed. Using immunohistochemical staining, the expression levels of tumour necrosis factor-α and interferon-γ in rat lung tissues were analysed and compared. Hematoxylin-Eosin staining of lung tissues showed that the rats with chronic obstructive pulmonary disease had severe pathological damages; compared to the blank group, while in rats treated with baicalin, bronchial obstruction, alveolar structure and inflammatory infiltration were improved, and the differences were statistically significant (p<0.05). After baicalin administration, the bronchial wall thickness in chronic obstructive pulmonary disease rats was reduced, collagen deposition in the bronchial epithelium was improved, and airway smooth muscle proliferation was alleviated compared to the control group. -

The conventional extraction techniques are mostly based on the use of mild/high temperatures (50–90 ◦C) that can cause thermal degradation, are dependent on the mass transfer rate, being reflected on long extraction times, high costs, low extraction efficiency, with consequent low extraction yields. Due to these disadvantages, it is of interest to develop non-thermal extraction methods, such as microwave, ultrasounds, supercritical fluids (mostly using carbon dioxide, SC-CO2), and high hydrostatic pressure-assisted extractions which works on the phenomena of minimum heat exposure with reduced processing time, thereby minimizing the loss of bioactive compounds during extraction. Further, to improve the stability of these extracted compounds, nano-encapsulation is required. Nano-encapsulation is a process which forms a thin layer of protection against environmental degradation and retains the nutritional and Citation: Noore, S.; Rastogi, N.K.; functional qualities of bioactive compounds in nano-scale level capsules by employing fats, starches, O’Donnell, C.; Tiwari, B. -

(2020). Total phenolic content, free radical scavenging capacity, and anti-cancer activity of silymarin. J. Food Bioact. 10: 53–63. Abstract Milk thistle (Silybum marianum) seeds are a good source of dietary polyphenols. The bioactive component of milk thistle seeds, silymarin, contains flavonolignans including silybin A, silybin B, isosilybin A, isosilybin B, sily- christin, isosilychristin, and silydiain along with the flavonol taxifolin. Silymarin is used traditionally as a natural herbal medicine with minimal side effects. Structurally, each silymarin component possesses phenolic hydroxyl groups and thus works as an antioxidant. In addition to free radical scavenging capacities, silymarin’s anti-cancer activities were reported for many different types of cancers including bladder, breast, colon, gastric, kidney, lung, oral, ovarian, prostate, and skin. The current review will discuss silymarin’s chemical components, total phenolic content, free radical scavenging capacities, and anti-cancer activities. -

Received August 18, 2015; Accepted January 12, 2016; Epub February 15, 2016; Published February 29, 2016 Abstract: Acute myeloid leukemia (AML) represents a heterogeneous group of hematological neoplasms with marked heterogeneity in response to both standard therapy and survival. Hispidulin, a flavonoid compound that is anactive ingredient in the traditional Chinese medicinal herb Salvia plebeia R. Br, has recently been reported to have anantitumor effect against solid tumors in vitro and in vivo. The aim of the present study was to investigate the effects of hispidulin on the human leukemia cell line in vitro and the underlying mechanisms of its actions on these cells. Our results showed that hispidulin inhibits AML cell proliferation in a dose- and time-dependent man- ner, and induces cell apoptosis throughan intrinsic mitochondrial pathway. Our results also revealed that hispidulin treatment significantly inhibits extracellular matrix metalloproteinase inducer (EMMPRIN) expression in both tested AML cell lines in a dose-dependent manner, and that the overexpression of EMMPRIN protein markedly attenuates hispidulin-induced cell apoptosis. -
Ameliorative Effects of a Combination of Baicalin, Jasminoidin and Cholic Acid on Ibotenic Acid-Induced Dementia Model in Rats

China, 3 The Laboratory Research Center of Xiyuan Hospital, China Academy of Chinese Medical Sciences, Beijing, P. R. China, 4 The Institute of Basic Clinical Medicine, China Academy of Chinese Medical Sciences, Beijing, P. R. China Abstract Aims: To investigate the therapeutic effects and acting mechanism of a combination of Chinese herb active components, i.e., a combination of baicalin, jasminoidin and cholic acid (CBJC) on Alzheimer’s disease (AD). Methods: Male rats were intracerebroventricularly injected with ibotenic acid (IBO), and CBJC was orally administered. Therapeutic effect was evaluated with the Morris water maze test, FDG-PET examination, and histological examination, and the acting mechanism was studied with DNA microarrays and western blotting. Results: CBJC treatment significantly attenuated IBO-induced abnormalities in cognition, brain functional images, and brain histological morphology. Additionally, the expression levels of 19 genes in the forebrain were significantly influenced by CBJC; approximately 60% of these genes were related to neuroprotection and neurogenesis, whereas others were related to anti-oxidation, protein degradation, cholesterol metabolism, stress response, angiogenesis, and apoptosis. Expression of these genes was increased, except for the gene related to apoptosis. Changes in expression for 5 of these genes were confirmed by western blotting. Conclusion: CBJC can ameliorate the IBO-induced dementia in rats and may be significant in the treatment of AD.
