ABSTRACT:These experiments were conducted in order to compare the effects of extractum cepae, heparin, allantoin gel (CTBX) and silver sulfadiazine (SSD) cream on burn wound healing in rats. Thirty six adult, female Wistar albino rats were divided into three equal groups. A burn was made on the back of all rats. The burned areas in the first, second and third groups were covered with cold cream (control), SSD skin cream and CTBX twice a day, respectively. Seven and 14 days later, the rats were sacrificed and burned skin tissue samples were collected from the rats for histopathological examinations. Histopatological evaluations on the 7 th and 14 th daysshowed burn healing to be better in the CTBX and SSD groups with respect to the control group. The best burn wound healing was observed in the CTBX group (P < 0.001). Wound healing was significantly different between the groups at days 7 and 14 (P < 0.001). In conclusion, application of CTBX has significant positive effects on the healing of burn wounds in a rat model.

“…cepa L. has been reported to have antioxidant properties. It contains polyphenols, flavonoids, kaempferol, quercetin, and their glycosides [13]. Spinach is also rich in polyphenols, flavonoids, steroids, and carotenoids, glycosides (such as coumarins, anthraquinones) which were shown to possess anti-inflammatory and antioxidant property [49].…”

Objective: This study was to evaluate complications of osteoporosis in ovariectomized rats and the possibility to ameliorate these changes by consumption of vegetable formula. Furthermore, transcription of mRNA of RANKL gene was matched with bone mass density (BMD) and bone formation marker (human procollagen 1 N terminal peptide [PINP]).Methods: Thirty rats were divided into three groups. The first is non ovariectomized control group (NOVXC), the second is ovariectomized control group (OVXC), and the third is ovariectomized rats supplemented with the vegetable formula (OVXT). Animals were fed for 8 successive weeks. Animals were treated and sacrificed under the recommended ethics of laboratory animal's treatment. The vegetable mixture was formulated with the purpose to correct the bone compromise and supply all the presumed deficient elements and hormone.Results: Chemical analysis showed that the formulated vegetable mixture had a high amount of flavonoids as catechin (100 mg/100 g of dry weight) and polyphenols as tannic acid (1000 mg/100 g dry weight. Furthermore, it had high reducing power (1,1-diphenyl-2-picrylhydrazyl radical showed inhibition percentage of 91.81%.). Several phytochemicals necessary for bone health were demonstrated in the vegetable mixture using highperformance liquid chromatography. RANKL/GAPDH mRNA transcription ratio showed marked an increase in OVXC versus the control NOVXC rats Conclusion:It may be concluded that the plant formula was effective to minimize health hazards in ovariectomized rats and maybe for postmenopause women. Perhaps longer time may be needed for more significant and clear effect.

“…De esta manera, las variedades rojas y amarillas parecen poseer un mayor porcentaje de compuestos fenólicos que las blancas. Prakash et al (2007) compararon el contenido fenólico y la capacidad antioxidante de variedades de cebolla verde, blanca, roja y morada y sugirieron que las variedades rojas tenían los contenidos en quercetina y kaempferol más altos. Gorinstein et al (2009) también concluyeron que las variedades rojas tenían el mayor contenido de compuestos bioactivos y la mayor actividad antioxidante.…”

“…También se observan diferencias entre las variedades, ya que en la cebolla 'Figueres' hay una menor diferenciación celular y una mayor cantidad de precipitados que en las otras dos variedades. Diversos estudios realizados en distintas variedades de cebolla muestran diferencias en el contenido fenólico dependiendo de la variedad.. Prakash et al (2007) compararon el contenido fenólico y la capacidad antioxidante de variedades de cebolla verde, blanca, roja y violeta y sugirieron que las variedades rojas tenían los contenidos en quercetina y kaempferol más altos. Gorinstein et al (2009) obtuvieron resultados similares, ya que concluyeron que las variedades rojas tenían el mayor contenido de compuestos bioactivos y la mayor actividad antioxidante.…”
