Abstract: Wound healing in some chronic diseases and disorders has become one of the challenges of medical
science and for this reason using the new compounds to accelerate wound healing is produced will be
welcomed. 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.

(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

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

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

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

day 3, none of the drugs used have preference over
another.
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

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). Eucerin
