Mục tiêu: Đánh giá tác dụng cải thiện rối loạn chuyển hóa Lipid máu của nano Alginate/Chitosan/ Lovastatin trên chuột cống trắng béo phì bằng thức ăn cao năng giàu chất béo. Đối tượng và phương pháp: 72 đực ở hai nhóm chế độ thường (n = 36) 36). Sau giai đoạn gây mô hình 7 tuần được chia đều ngẫu nhiên làm 6 gồm: 1) thường-uống nước muối (C-NaCl), 2) liều 4 mg/kg (C-Lovastatin), 3) tổ hợp Algin...

Several attempts have been made to improve the solubility of water insoluble drugs. Over the years, inclusion complexation of drugs with β-cyclodextrin has emerged as a viable attempt to improve the dissolution of water insoluble drugs. The aim of the present work was to improve the dissolution rate of lovastatin, a water insoluble drug, by inclusion complexation with β-cyclodextrin. The stoich...

in the present study, 110 fungal strains of persian type culture collection (ptcc) including some selected strains isolated in various screening projects were tested for their potentiality to produce lovastatin, a competitive inhibitor of 3-hydroxy-3-methylglutaryl-coa reductase (hmg-coa reduc-tase), the rate-limiting enzyme of cholesterol biosynthesis. the fungal strains were cultivated in a t...

Lovastatin production is dependent on the substrates provided. We investigated how several carbon and nitrogen sources in the medium affect lovastatin production by Monascus pilosus. M. pilosus required a suitable concentration of organic nitrogen peptone for high lovastatin production. As sole carbon source with peptone, although glucose strongly repressed lovastatin production, maltose was re...

Development of a novel method for the quantification of lovastatin is an interesting problem in the analytical field. In the literature, many reports use spectrophotometric method for the quantification of lovastatin. However, the analysis of fermentation broth containing lovastatin appears to be inaccurate using spectrophotometric method. Hence, the estimation of lovastatin produced by Monascu...

Cholesterol synthesis in the human body can be catalyzed by coenzyme HMG-CoA reductase, and lovastatin, a key enzyme inhibitor, reduce hypercholesterolemia. Lovastatin obtained as secondary metabolite of Aspergillus terreus ATCC 20542. In this study, rice straw lignocellulose was used aeration agitation bath fermentation 1-L flask, maximal crude extraction rate 473 mg/L lovastatin obtained. The...

Glioblastoma is a common malignant brain tumor and it is refractory to therapy because it usually contains a mixture of cell types. The tumor necrosis factor-related apoptosis inducing ligand (TRAIL) has been shown to induce apoptosis in a range of tumor cell types. Previously, we found that two human glioblastoma cell lines are resistant to TRAIL, while lovastatin sensitizes these glioblastoma...

Statin at appropriate concentrations has been shown to induce odontoblastic differentiation, dentinogenesis, and angiogenesis. However, using a carrier to control statin release might reduce toxicity and enhance its therapeutic effects. The aim of this study was to prepare poly(d,l-lactide-co-glycolide acid) (PLGA) nanoparticles that contain lovastatin for application in direct pulp capping. Th...

This paper reports the results of an extensive survey on the levels of lovastatin in Pu-erh tea samples. The microbial source of lovastatin was assessed by testing the ability of fungi with higher isolation frequency in the Pu-erh tea samples to produce lovastatin on Czapek yeast extract agar (CYA). Lovastatin was not detected in any of the raw Pu-erh tea samples without storage but was found i...
