ObjectiveTo evaluate wound healing potential of flavonoid fractions of Martynia annua (M. annua) Linn. leaves in diabetic rats on the basis of folkloric information and preliminary study.MethodsThe flavonoid compound luteolin and apigenin were isolated from dried leaves of plant by column chromatography. The two concentrations (0.2% and 0.5% w/w) of luteolin and flavonoid fraction were selected for topically applied as ointment on diabetic wound. The Povidone Iodine Ointment USP was used as a reference. On 18th days, protein content, hydroxyproline and antioxidants (SOD, CAT and GSH) level in granuloma tissues were determined.ResultsThe results showed that, percent wound contraction were observed significantly (P<0.01) greater in MAF fraction and 0.5% w/w of luteolin treatment groups. Presence of matured collagen fibres and fibroblasts with better angiogenesis were observed in histopathological studies.ConclusionsIn conclusion, our findings suggest that flavonoid fraction (MAF) and luteolin (0.5% w/w) may have potential benefit in enhancing wound healing in diabetic condition, possibly due to free-radical scavenging activity of plant. 相似文献

Objective
To evaluate the wound healing potential of fractions from ethanol extract of Martynia annua (M. annua) Linn leaves.Methods
Ethanol extract of M. annua Linn leaves was fractionate into three different fractions (MAF-A, MAF-B and MAF-C) which were screened for wound healing potential using two models: excision and incision on rats. The thin layer chromatography (TLC) profile of all fractions were analyzed and TLC of luteolin was also done. The Povidone-Iodine Ointment was used as reference for comparision. Excision and incision wounds were created on dorsal portion of rats for study. Wound contraction, biochemical parameters (protein level and hydroxyproline level) and histopathological study were performed in excision wound model whereas incision model was used for determination of tensile strength.Results
The wound contraction and tensile strength of skin tissues were observed significantly greater in MAF-C fraction treated group than other two fractions (P<0.01). In excision wound method (on day 18) protein content and hydroxyproline were found significantly higher in MAF-C group than control group (P<0.01). Histopathological study also showed better angiogenesis, matured collagen fibres and fibroblast cells as compared with the control group.Conclusions
In conclusion, our findings suggest that fraction MAF-C from ethanol extract of M. annua leaves is found most effective in wound healing. 相似文献6.
Major consequences of untreated severe mitral regurgitation (MR) includes heart failure, ventricular remodeling and pulmonary hypertension leading to significant morbidity and mortality. MitraClip is the most widely used device for treatment of severe MR. To overcome some of the shortcomings of MitraClip, novel devices like PASCAL mitral valve repair system are developed. We performed a single arm meta-analysis for patients with severe mitral regurgitation (MR) undergoing PASCAL mitral valve repair system. The results showed that 93.8% patients had reduction in MR grade, with an average operative time of 88 min and an average increase of 86.33 m in 6-min walk test. 相似文献

Neuro-cysticercosis (NCC) and Japanese encephalitis (JE) are common in tropical countries. Two cases of NCC with coexistent JE are presented, which share same socio-demographic and ecologic factors and have the same intermediate host (pig). Patients were on treatment for NCC and presented in comatose state. Sudden clinical deterioration of a patient with NCC should warrant a search for coexistent JE. We report findings of magnetic resonance spectroscopy and diffusion-weighted imaging of the JE. 相似文献

Air in the orbit is usually a result of trauma to the orbit but here we report a case of spontaneously occurring orbital Pneumatocele
which followed about of sneezing and clearing of nose. The rare site communication at frontoethmoid junction is highlighted
with relevant review of literature. 相似文献
