Under abnormal vascular conditions, VSMCs undergo a phenotypic transformation, leading to enhanced cell proliferation, migration, and matrix synthesis. This contributes to the development of vascular diseases such as atherosclerosis, arteriosclerosis, and restenosis. During this process, platelet-derived growth factor (PDGF)-BB is a key inducer of the VSMC phenotypic transformation. <i>Abelmoschus manihot</i> (L.) Medic flower (AMf) is known for its rich nutritional value and traditional medicinal uses. Its extract has been clinically used to treat kidney diseases, but its impact on VSMCs has not been documented. This study explored the inhibitory effects of AMf ethanol extract (AME), hot water extract (AMW), and supercritical CO<sub>2</sub> extract (AMS), and their five indicator components (rutin, quercetin, isoquercitrin, myricetin, and hyperoside) on PDGF-BB-stimulated proliferation and migration using a rat aortic smooth muscle cell (RASMC) model. Both AME and AMS showed a significant dose-dependent inhibition of PDGF-BB-induced RASMC proliferation and migration, with AME being more effective than AMS. In contrast, AMW had no effect. The five indicator compounds also showed excellent inhibitory effects. AME treatment effectively reduced the phosphorylation of JNK, ERK, p38, and NF-κB, and downregulated the expressions of the migration-promoting factors <i>MMP-2</i> and <i>MMP-9</i> in PDGF-BB-stimulated RASMCs. These findings suggest that AME protects VSMCs by regulating the phosphorylation of the MAPK/NF-κB pathway and suppressing MMP expression.

However, tea consumption may influence biological functions because of its high polyphenol and methylxanthine content. Theophylline is a methylxanthine that plays a significant role in respiratory physiology and is used clinically as a bronchodilator. In this study, we assessed the pharmacological safety of theophylline by investigating its effects on the respiratory responses of experimental rodents. Six-week-old male Sprague-Dawley rats were intravenously administered 0, 2.5, 5, or 10 mg/kg theophylline. After systemic theophylline exposure, the respiratory rate, tidal volume, and minute volume were monitored and statistically analyzed. There was a significant increase in respiratory rate and minute volume with no change in tidal volume at theophylline doses of >5 mg/kg. Changes in respiratory rate and minute volume peaked at 0.25 h after exposure; the respiratory rate increased by 58.2% and 88.9%, and the minute volume increased by 50.5% and 72.8% with the 5 and 10 mg/kg doses, respectively, compared with the vehicle control. These results provide fundamental scientific data that can be used in clinical applications.</p>","PeriodicalId":16440,"journal":{"name":"Journal of medicinal food","volume":" ","pages":"508-512"},"PeriodicalIF":1.7,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143189318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
