Description of a new method of ovariectomy in female rats.

Abstract:

:Rats are currently the most used laboratory animals to investigate osteoporosis. We report an efficient method of ovariectomy and compared this method with the two other operative methods of ovariectomy (i.e., midline dorsal skin incision and double dorsolateral approach, which are used commonly for inducing experimental osteoporosis. Female Wistar rats, 12 weeks old, were divided into three groups. Ovariectomy was preceded by a single midline dorsal skin incision, 3 cm long, in the group A; double dorsolateral incisions, approximately 1 cm long, in the group B; and a single ventral transverse incision of 0.4-0.6 cm at the middle abdominal region in the group C. Animals in groups A, B, and C had a mean weight of 258.12 ± 0.54 g, 255.78 ± 0.42 g, and 254.55 ± 1.69 g, respectively. There were significant differences in the duration (in minutes) of surgery in the groups B (9.65 ± 0.86) and C (7.55 ± 0.11, P < 0.001) when compared to the group A (15.52 ± 0.30) and in the group B (P < 0.01) when compared to the group C. Wound healing time (in days) for groups B (9.22 ± 0.67) and C (8.01 ± 0.93) was significantly shorter than that for group A (11.58 ± 1.2, P < 0.001), with the wound healing time for group C being slightly shorter than that for group B. The surgery, as conducted in the group C, was technically easier, less time consuming and showed less wound healing duration.
