In the meantime, the Myrtus herb has antibacterial and anti-inflammatory, antiseptic and anticongestive effects. Based on this information, the purpose of this study was to studying the effect of this plant extract on process of wound healing. In this study, after induction of anesthesia in 48 male rats weighing 200 to 250 g and approximately one and a half months of age, using a biopsy punch with a diameter of 23 mm circular wound was created on the dorsal skin region of each of them. Then the rats were divided into four groups, each groups continued healing process with 5 and 10% extract of Myrtus herb mg/cm 2, 35 dose oncedaily, eucerin (drugs) and control (distilled water). Test duration was 28 days, wound diameter measurement using digital image analysis and Histopathological study on days 0, 3, 7, 14, 21 and 28 with biopsy two rats from each group were took. These rats were removed from the investigation process after obtaining biopsies. Obtained Results were analyzed with ANOVA and TUKEY test (p<0.05). The results revealed that treatment with low-dose group of Myrtus herb extract (5%) most shrinkage of wound area and also from the perspective of Histopathological change. in the second and third week, tissue had better organization than most other groups (p<0.05), but the group treated with high doses of Myrtus herb extract (10%) had less wound shrinkage and organization. Key words: Healing, myrtus communis, rat, skin wounds, zinc oxide "-terpinyl acetate (0.5%), p-cymene (0.8%), (-terpinene (0.6%), terpinen-4-ol (0.3%), methyl chavicol (0.7%) and methyl iso-eugenol (0.2%), along with minor components (Chevalier, 1996; Newall et al., 1996). Myrtus communis oil is tested non-toxic, non-irritant, non-sensitising and non-phototoxic. Myrtus oil is used with great benefit on de-vitalized, irritated and inflamed skin as well as in case of acne and generally problematic skin. Even though it is especially recommended for oily skin, it can be used on all skin types since its action being mainly balancing and revitalizing. Because of its sedative qualities, it is a good remedy in cases of insomnia and nervous conditions. It is especially recommended for children and older people in cases of respiratory afflictions, chronic lung conditions, colds, infections and bronchial catarrh (Muria et al., 1995). Zinc oxide is an inorganic compound with the formula ZnO. It is a white powder that is insoluble in water. Zinc is an essential trace element of which about 2 g is found in the adult human body. At least 200 enzymes in different biological systems are dependent on INTRODUCTION Myrtus communis, the myrtle belongs to the family of the Myrtaceae, and is a beautiful evergreen bush or small tree with small elliptic, fragrant, deep green leaves and pure white flowers. The flowers are extremely beautiful, star-like with 5 white petals and numerous protruding stamens. Although a native of North Africa, it is today naturalized around the Mediterranean basin and commercial oils are produced in France, Tunisia and Morocco. The oil has been known and valued from ancient times for its delicate, pleasant, clear and fresh scent. The plant is assigned to the goddess Aphrodite (Venus). Myrtus communis oil has the main components "-pinene (18%), limonene (20%), 1.8 cineole (5%), linalool (16%), linalyl acetate (8.16%), myrtenyl acetate (9%), geranyl acetate (3%), "-humulene (2%), "-terpineol (1.5%), trans-caryophyllene (1%), methyl eugenol (1%), trans-$-ocimene (0.9%), "-terpinolene (0.9%), along with minor quantities of eugenol (0.4%), neryl acetate (0.4%), Corresponding Author: Ali Rezaie, Department of Clinical Science, Tabriz Branch, Islamic Azad University, Tabriz, Iran 176 Curr. Res. J. Bio. Sci., 4(2): 176-185, 2012 the presence of the zinc ion. Among these zinc-dependent enzymes, DNA and RNA polymerases are crucial during tissue repair as they affect cell proliferation and protein synthesis. In accordance with the biochemical role of zinc a reduced synthesis of DNA, reduced deposition of granulation tissue, decreased tensile strengths in skin incisions, and delayed closure rates in excised wounds in zinc-deficient rats have been demonstrated (Prasad and Oberleas, 1974; Sandstead et al., 1970). Zinc supplementation restored to normal the tensile Strengths of the incisional and healing rates of the excisional wounds (Sandstead et al., 1970). It has been clinically shown that the healing of leg ulcers is delayed in patients with subnormal serum-zinc levels (Haley, 1979). Zinc given as oral and topical zinc sulfate or as topical zinc oxide normalizes impaired healing ability in these patients (Golden et al., 1980; Haley, 1979; Stromberg and Agren, 1984). The objective of this study was to determination of the Effect of Myrtus communis on healing of the experimental skin wounds on rats and its comparison with zinc oxide. biopsy punch were inducted. In this study rout of wounding was excisional wounding that in way epidermis, dermis, hypoderm and Panniculus Carnosus completely were removed. After wounding, rats were divided into five groups of ten. Group 1: (rats from No. 1-10) received high doses (10%) of herbal extract Group 2: (rats from No. 11-20) received low doses (5%) of herbal extract Group 3: (rats from No. 21-30) as positive control group received zinc oxide 20% Group 4: (rats from No. 31-40) received eucerin Group 5: (rats from No. 41-50) as control not received any drug Samples were fixed in the formalin 10% and sent to pathology laboratory. Post-operation measures: After biopsy and washing wound area with normal saline, all drugs were administrated as local way by an applicator in the wound area. This administration continued for 28 days. 35 mg per cm2 of wound area Myrtus communis and zinc oxide ointments and eucerin through local way were administrated to each group with exception group 5. MATERIALS AND METHODS Animals: This study was conducted in Islamic Azad University during 2011. In this study, 50 female wistar rats weighted 180-220 g and aged 12 weeks old were selected. Sampling: On days 0, 3, 7, 14, 21 and 28 of research, samples as tissue specimens from biopsy areas were collected and sent to pathology laboratory. Sampling was done under anesthesia condition and this anesthesia was induced by Ketamine and Rampon. Sampling was exerted by scalpel. Samples were fixed into formalin 10%. In lab, after processing and staining to H&E method slides were achieved. Slides were investigated by a light microscope. Data were analyzed by SPSS ver.17 and MATLAB ver. 7.8 and TUKEY test. Pre-operation measures: The operation (induction wound in the skin) required general anesthesia, analgesia and muscle relaxation. In term, we used of Ketamine (10%, 40 mg/kg) and xylazine (2%, 10 mg/kg) to induction of anesthesia and pre-operation drugs, respectively. Administration route was IM from hind limb. RESULTS Operation measures: After preparation the dorsal skin of rats (distinct between scapula to ischial tuberosity), a wound in circle shaped with 23 mm in diameter and by Geometric findings: From day 1 to day 3, wound area was expanded increasingly in all groups that this Table 1: Comparison of groups from wound area aspect on day 3 Descriptive statistics ------------------------------------------------------------------------------------------------------------------------------------------------------------Mean -------------------------------------------Days.3 N Range Minimum Maximum Statistic SE SD Control 10 1.8144 5.7069 7.5213 6.560470 0.1970758 0.6232085 Eucerin 10 1.9820 5.1509 7.1329 6.297320 0.2407432 0.7612968 Zinc Ox. 10 1.4144 5.1837 6.5981 5.828960 0.1548517 0.4896842 Low D. 10 1.8884 5.1942 7.0826 5.859270 0.1931686 0.6108528 High D. 10 1.7628 5.4328 7.1956 6.257160 0.2086076 0.6596751 Table 2: Comparison of wound areas mean among understudying groups on day 3 by ANOVA df MS Day 3 SS Between groups 3.887 4 0.972 Within groups 18.145 45 0.403 Total 22.032 49 - 177 F 2.410 - Sig. 0.063 - Curr.

ANOVA test results also present non-significant data on day 3 between groups. With comparison of above data revealed that there was significant difference between control and other groups on day 7. Also this difference is seen between low dose and zinc oxide groups. According to the results on day 14 revealed that there was significant difference between groups. Note that average deviation was lower in low dose group than others. Based on data resulted from TUKEY test revealed that low dose and zinc oxide groups have showed same results and good results than other groups. Note that eucerin showed good and significant results than control group. phenomenon because of matching with inflammation phase is justifiable. However, in this mean on day 3, treatment group 3 had lowest voluminosity than other area, so that on day 7; the lowest wound area was belonged to same group. After this group, other groups from reduction in wound size aspect were including groups 3, 1, 4 and control, respectively. On day 14 with exception control and high dose groups, others had good reduction in wound size so that low dose, zinc oxide and eucerin were in 1 to 3 occupations respectively. On day 21, groups 3 and control showed partial same results with low dose and group 4 respectively. Finally on day 28, all rats have showed good results that it is not an unexpectable issue but only group 1 have showed low results. The results are detailed in the Table 1-15. Based on data showed on Table 1 revealed that there was no significant difference between groups because on 178 Curr. Res. J. Bio.

Sci., 4(2): 176-185, 2012 DISCUSSION in total duration showed better results than the control group. Although Eucerin is considered a neutral substance but there are certainly legitimate reasons for this significant difference that possibly creating a protective layer over the wound and reduce entry into the wound infectious agents can be effective in this. However for obtaining accurate results, specific experiments are requiring. In conclusion can be mention that Myrtus communis is good replacement against other chemical drugs which are used widely. Non-steroidal anti-inflammatory drugs, or NSAIDs, are common medicines used to treatment of signs after surgery. NSAIDs stop cells making prostaglandins. Prostaglandins are chemicals released by injured cells. They cause inflammation and swelling and they sensitize nerve endings, which can lead to pain. If you make less prostaglandin, you have less inflammation and less pain. By stopping cells making prostaglandins, NSAIDs relieve the symptoms of pain and inflammation. These drugs have more side effects thus use of other replacements such as herbal extracts which had anti-inflammatory groups. After times, low dose treatment group with veryhigh acceleration starts to reduce in size of the wound effects is very important. On the basis of different studies conducted so far regarding Myrtus communis, it has been observed that, this herb has antibacterial and antifungal (Gharnieh, 1994; Saboor, 1995; Salehniya, 1988), antiinflammatory (Kindersley, 1995; Kindersley, 1996; Zargari, 1995), sooding (Kindersley, 1996; Zargari, 1995), and analgesic effects. Note that in this study revealed Myrtus communis 5% has more positive effect than Myrtus communis 5%. This reason not clearly understood and needs to other researches. Zinc oxide also used topically on wounds is a folk remedy believed to promote healing. However, there is to date no clear scientific proof as to its effectiveness on wound healing in humans or experimental animals which are not zinc deficient (Murray and Rosenthal, 1968; Norman et al., 1975; Sandstead et al., 1970; Williams et al., 1979). In one study that carried out by Williams et al. (1979) revealed that no significant difference in rate of reepithelialization and healing was observed between zinctreated and control wounds studied for more than 21 days. A significantly more rapid healing was found in cephalad wounds in comparison to caudad wound. Serum zinc levels in the rats showed a significant rise of 85% over the 3-week period, indicating zinc absorption through the wound. Based on results of this trial, extract about 5% cream is accelerated process of skin wound healing, However the zinc oxide ointment also been shown to have good effect. Only unpredictable weak results was the 10% Myrtus plant extract ointment that finally shown weak effects on wound healing than control groups. independent study is needed to justify this results but According to the author's personal experiences and studies it is likely that Toxic effects of high doses of Myrtus plant extract caused the poisoning of treated animals. Fibroblasts are responsible for the synthesis of collagen and connective tissue fibers. cases the maturation of connective tissue. Since the Myrtus extract stimulate the activity of fibroblasts and macrophages, this two cells in interaction with each others with the stimulation of regenerated vessel to granulation tissues, Makes to healing more quickly (Luisa and Dipietro, 2003).
