The root contains a copious purple dye[]. Special Uses Cultivation details We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors in many parts of this country. The following notes are based on the general needs of the genus. Requires a well-drained gritty soil and a sunny position in the rock garden or on a dry wall[1].

Abstract BACKGROUND Burn is still a majordevastating condition in emergency medicine departments among both genders and all age groups in all developed and developing countries, leading to physical, psychological scars and economical burden. The present study aimed to determine the healing effect of topical treatment with Arnebia euchroma on second-degree burn wound in rats.

The mean of burn area, percentage of wound contraction, histopathological and bacteriological assessments in the injured area were dtermined during the study. It is a crucial factor of morbidity and mortality, throughout the world, especially in the developing countries. Burn wound healing is a complex process including inflammation, granulation, and remodeling of the tissue. Silver sulfadiazine SSD is applied as standard topical therapy in healing of burn wounds with antibacterial activitities.

It might also delay of the wound healing. Previous studies were reported that SSD cream should not be used for long time on extensive wounds. The use of natural products to support of the wound healing is a common practice in the world.

For centuries, the medicinal plants have been extensively used in wound healing of burned injuries. Johst from the Boraginaceae family grows in different countries such as India, North Africa, Turkey, Himalaya and Iran especially in the mountain areas in north of Iran. It was confirmed by botanists Dr. Masoud and Dr. The roots of the A. The dried materials were powdered in a grinder.

Then samples were sieved and levigated with glycerine. Finally, liquid paraffin and eucerin were added and mixed. This formulation with the weight ratio of AEO All formulations were filled in tubes and stored in 4, 25, and C for two weeks and the stability of ointments were evaluated. All animals were obtained from this university. Animals were allowed free access to laboratory food and water ad libitum.

Deep anesthetized rats were kept in prone position. All wounds were washed with normal saline, and wound in each group was applied with cream and dressed. Wounds were dressed once per day.

Rats were washed with normal saline before dressing in all groups. In order to quantify the rate of wound healing, the size of lesions was determined on 1, 3, 7, 10, 15, 20, 25, and 30 days after burn injury.

The wound area was displayed as cm2. The area of wounds at each day was determined by a formula, where represents the area cm2 by length, and latitude rectangular. Also, the sum of the scales in each part of histopathological evaluation was divided to four groups.

We evaluated extent of granulation tissue, the new dermis, collagen organization and re-epithelization, according to Table 1 as a histological study. Light microscopy was used to assessing pathological changes.
