The present study examined the therapeutic effects of bone marrow mesenchymal stem cells (BM-MSCs) and adipose-derived mesenchymal stem cells (AD-MSCs) in methotrexate (MTX)-induced pulmonary fibrosis in rats as compared with dexamethasone (Dex). MTX (14 mg/kg, as a single dose/week for 2 weeks, p.o.) induced lung fibrosis as marked by elevation of relative lung weight, malondialdehyde, nitrite/nitrate, interleukin-4, transforming growth factor-β1, deposited collagen, as well as increased expression of Bax along with the reduction of reduced glutathione content and superoxide dismutase activity. These deleterious effects were antagonized after treatment either with BM-MSCs or AD-MSCs (2 × 10(6) cells/rat) 2 weeks after MTX to even a better extent than Dex (0.5 mg/kg/ for 7 days, p.o.). In conclusion, BM-MSC and AD-MSCs possessed antioxidant, antiapoptotic, as well as antifibrotic effects, which will probably introduce them as remarkable candidates for the treatment of pulmonary fibrosis.
Flavonoids have reported to cover interesting multiple pharmacological properties. This study evaluated the effect of apigenin or silymarin in paw inflammation induced by formalin in mice. Mice were divided into four groups: I: positive control group; II: apigenin, 3 mg/kg (i.p.); III: silymarin 50 mg/kg (p.o.); IV: meloxicam 10 mg/kg (p.o.), the reference drug. Therapies were administered once a day for 7 days. The curative effects were assessed on inflammatory, oxidative stress and neurotransmitter biomarkers, and apoptosis. Both flavonoids induced marked improvement in paw licking time, paw edema %, malondialdehyde content, superoxide dismutase, and sorbitol dehydrogenase activities, with slight progress in paw interlukin-1β. Additionally, silymarin augmented brain content of dopamine and norepinephrine. Furthermore, flavonoids induced marked decline in extent of apoptosis. So, the results spotlight on the good influence of apigenin or silymarin as anti-inflammatory, antioxidant, and antiapoptotic agents in formalin-induced mice paw inflammation to even a better extent than meloxicam.
The co-presence of nasal polyps and resistant otitis media with effusion should raise the possibility of eosinophilic granulomatosis with polyangiitis.
Rutin, naturally occurring flavonoid, has reported to cover interesting multiple pharmacological properties. This study evaluated rutin or/and meloxicam effects in paw inflammation induced by formalin in mice. Mice were divided into four groups: I-Formalin group, II-Rutin 60 mg/kg (p.o.), III-Meloxicam 10 mg/kg (p.o.), plus IV-Combined rutin and meloxicam. Therapies were administered once a day for 7 days. The curative effects were assessed on inflammatory, oxidative stress, and apoptosis. Both rutin and/or meloxicam induced marked improvement in paw licking time on the 1st day and by combined treatment only on the 3rd day as well reduction in paw edema% on the 3rd day. Moreover, noticeable progress in liver malondialdehyde content, superoxide dismutase, and sorbitol dehydrogenase activities as well decline in paw interleukin-1β level and extent of apoptosis. The results spot light on the good influence of combined rutin and meloxicam in formalin-induced mice paw inflammation to a better extent than either rutin or meloxicam lonely.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
