In this study, the effects of three different ozonated oils (Sesame, Nigella sativa and Hypericum perforatum) on wound closure rate, healing process and possible complications were examined macroscopically and microscopically. Twenty-one adult Wistar albino female rats were used in the study. Subjects were divided into three groups, early wound healing, (7 days), medium wound healing, (14 days) and late wound healing (21 days). Four full-thickness skin wounds of equal size (10 mm in diameter) were formed on the back regions of all rats. This region was chosen for preventing self-inflicted injuries and reducing external irritation. The wound was left open during the healing process. While the first wound (control) received no treatment in the second wound, ozonated Sesame oil, in the third wound ozonated Nigella sativa oil and in the fourth wound ozonated Hypericum perforatum oil were used. No group obtained parenteral drug administration. First, second and third main groups were euthanized on days 7, 14 and 21, respectively. The wound healing was assessed macroscopically daily. Wound sizes of individual rats were measured with a caliper and digitally photographed every day from the day of injury. After euthanasia, all wound sites of the subjects were evaluated histopathologically.There were no significant differences in wound healing between treatments in the first day 7. On they 14, it was found that the healing was better in the group applied Nigella sativa and Sesame oils (p≤0.05). On day 21 wound healing was completed in all subjects with a resultant of better outcome in Nigella sativa oil treatment compared with others (p≤0.01).In this study the best wound healing outcome was achieved with Nigella sativa oil and Sesame oil where three different minced oils were used.

The advantages of ventral and flank approaches for ovariohysterectomy (OHE) in terms of wound healing rate when compared to each other are still understudied. The effects of different OHE approaches on the wound healing rates of cats in Selangor, Malaysia were investigated. A total of 50 female cats were randomly included in this study. They were divided into the ventral-approach group (n=25) and the flank approach group (n=25). The wound healing rates and possible complications that could arise from the surgery in all cats were monitored daily from Day 1 until Day 7 post-surgery. Data were analysed using Independent T-test. Overall, the incision site wound healing rate in cats from the flank-approach group was found to be significantly higher (P < 0.05) than in cats from the ventral-approach group (72.55 ± 3.48 % vs. 59.91 ± 3.34 %; mean ± SEM). Complete healing of the incision site was observed in 12 % of cats from the flank-approach group as compared to 8 % of cats from the ventral-approach group. However, 8 % of cats from the ventral approach group had post-surgery complications whereas the flank-approach group had none. Results from the alternative approach may be attributed to reduced accessibility and contamination of the incision site during recovery
