AMAÇ
Bu çalışmada, yanık yaralarında yaygın olarak kullanılan
çinko oksit ve gümüş sülfadiazinin tedavi etkileri karşılaştırıldı.
GEREÇ VE YÖNTEM
Yeni Zelanda cinsi 20 tavşanda pirinç propla yanık yarası
oluşturuldu. Tavşanlar rastgele iki gruba ayrıldı. Yanıklar
günlük uygulamayla birinci grupta çinko oksitle (Grup O),
ikinci grupta (Grup S) gümüş sülfadiazinle tedavi edildi.
Yara iyileşmesi klinik ve histopatolojik olarak takip edildi.
Yara ölçümleri yapıldı ve %50 ve %80 reepitelizasyona
ulaştığı günler belirlendi.
BULGULAR
Ortalama %50 ve %80 reepitelizasyona ulaşma süreleri
Grup O’da sırasıyla 21,4 ve 25,4 gün, Grup S’de 25,8 ve
30,2 gündü (p<0,001). Yara kolonizasyonu ise 1, 2, 3, 4, 5
ve 6. haftalarda ortalama olarak Grup O’da daha düşüktü.
Fark 2, 3, 4 ve 6. haftalarda anlamlı idi (p<0,001). Histopatolojik
değerlendirme sonucunda Grup O’da epidermis,
dermis ve skar dokusunun kalınlıkları sırasıyla 0,12, 3,80
ve 2,44 mm idi. Grup S’de ise 0,16, 4,76 ve 3,16 mm olarak
bulundu (p<0,001).
SONUÇ
Bu deneysel çalışmada, çinko oksit yanık tedavisinde epitelizasyon,
epidermis maturasyonu ve skar oluşumunda gümüş
sülfadiazinden daha etkili bulunmuştur.
Anahtar Sözcükler: Çinko oksit; gümüş sülfadiazin; parsiyel kalınlıktaki
yanık.
BACKGROUND
We aimed to compare the effects of topical zinc oxide and
topical silver sulfadiazine in the treatment of partial-thickness
burn wounds.
METHODS
The study was conducted with 20 New Zealand rabbits, and
burn wounds were created by a brass probe. The animals
were randomly divided into two groups. The burns were
treated with zinc oxide (Group O) or silver sulfadiazine
(Group S) with daily application. The wound healing process
was followed both clinically and histopathologically.
We determined the days at which 50% and 80% re-epithelization
was observed.
RESULTS
The mean time for 50% and 80% re-epithelization was 21.4
and 25.4 days in Group O and 25.8 and 30.2 days in Group
S, respectively (p<0.001). The mean score for wound colonization
was lower in Group O. The difference was statistically
significant at weeks 2, 3, 4, and 6 (p<0.001). In the
histopathological examination, the thicknesses of the epidermis,
dermis and scar tissue were 0.12 mm, 3.80 mm and
244 mm in Group O, and 0.16 mm, 4.76 mm and 3.16 mm
in Group S, respectively (p<0.001).
CONCLUSION
In this experimental burn study, zinc oxide was more effective
than silver sulfadiazine in terms of epithelization,
dermis maturation and scar formation.
Key Words: Zinc oxide; silver sulfadiazine; partial-thickness burn.

In the treatment of burns, the aim is to treat burns,
prevent infections and achieve the best functional and
aesthetic results in a shorter time with lower costs.
While healing burn wounds, a topical agent should
decrease the rates of mortality and morbidity by preventing
bacterial contamination and sepsis. The agent
should also be easily accessible. An ideal agent with
those properties has yet to be marketed. In the topical
treatment of burn wounds, 1% silver sulfadiazine
(SSD) pomade is the most commonly used agent
worldwide.[1] SSD has been shown to decrease bacterial
contamination, to hasten epithelization and to delay
wound contraction.[2-8] However, SSD is also known to
delay wound healing and separation of scar tissue, to
cause atrophic and hypertrophic scars, especially more
than three weeks after the applications, to have renal
toxicity, to cause leukopenia, and to carry a risk for
resistance.[9-19]
Zinc is an essential element for the human body,
and at the meeting of the World Union of Wound Healing
Societies in Paris in 2004, it was accepted as having
potential benefits in wound healing.[20] There are
studies showing the benefits of systemic and topical
use of zinc in wound healing. It is also reported that
zinc accelerates the wound healing process when applied
on open wounds.[21]
To our knowledge, no study exists in the literature
comparing the effects of local application of SSD and
oxide zinc ointment (OZO) in burn wounds. Therefore,
the present study was designed to compare the
effects of topical SSD and OZO in experimental partial-
thickness burns in rabbits.
MATERIALS AND METHODS
Study design
Permission was obtained from the ethical board
of Meram Medical School of Selçuk University. The
study was designed under the criteria of the Health
Guide for the Care and Use of Laboratory Animals
by the National Institutes of Health (NIH Publication
No: 86-23, Revised 1985 Bethesda). The research was
conducted at the Experimental Research Center of
Selçuk University. The weight of rabbits ranged from
3200-3600 g. The rabbits were accommodated in a
12/12 hour light and dark cycle at 22-26°C and fed
with a standard
