Bottom Line: Tissues were stained with Masson's trichrome dye in order to evaluate the amount of fibrous tissue reaction for histopathological examination; there was no significant difference in the amount of fibrous tissue between groups 1 and 2, while a very marked increase in the fibrous tissue was detected in groups 3 and 4.Mean tissue hydroxyproline levels of the groups 3 and 4 on 7th POD were 1.30 and 2.72 μg/g-protein, respectively.The difference between the groups was statistically significant (p = 0.001).

ABSTRACT

Aim: To evaluate the effect of thymoquinone on the healing of experimental left colon anastomosis in rats.

Methods: Forty Wistar albino rats weighing 250-300 g were randomly divided into four groups (10 rats/group). Group 1 (control group) rats were not administered Thymoquinone (TQ) for 3 days after the operation. Group 2 was administered daily TQ for 3 days starting from the first day after the operation. Group 3 was not administered TQ for 7 days after the operation. Group 4 was administered daily TQ for 7 days starting from the first day after the operation. Thymoquinone was administered as a single dose oral gavage through a 4F feeding catheter per each day. The bursting strength of the anastomosis was measured on 3rd and 7th postoperative days (POD) and resection was performed. Subsequently, the hydroxyproline level in the resected tissue was measured and a histological evaluation was performed.

Results: The bursting pressures of the anastomoses were measured to be statistically significantly greater on 7th POD in TQ administered groups compared to those without TQ administration. Tissues were stained with Masson's trichrome dye in order to evaluate the amount of fibrous tissue reaction for histopathological examination; there was no significant difference in the amount of fibrous tissue between groups 1 and 2, while a very marked increase in the fibrous tissue was detected in groups 3 and 4. Mean tissue hydroxyproline levels of the groups 3 and 4 on 7th POD were 1.30 and 2.72 μg/g-protein, respectively. The difference between the groups was statistically significant (p = 0.001).

Conclusions: TQ significantly increased the bursting pressure of the anastomosis, tissue hydroxyproline level, and fibrous tissue production.

Mentions: The tissues were stained with Masson’s trichrome dye in order to evaluate the fibrous tissue reaction and they were scored as described on Table 3. Scoring was performed as follows: no fibrosis formation: 0; very little activity: 1; a marked connective tissue proliferation: 2; and severe and mature connective tissue proliferation: 3 (Table 3; Figs. 4, 5).Table 3

ABSTRACT

Aim: To evaluate the effect of thymoquinone on the healing of experimental left colon anastomosis in rats.

Methods: Forty Wistar albino rats weighing 250-300 g were randomly divided into four groups (10 rats/group). Group 1 (control group) rats were not administered Thymoquinone (TQ) for 3 days after the operation. Group 2 was administered daily TQ for 3 days starting from the first day after the operation. Group 3 was not administered TQ for 7 days after the operation. Group 4 was administered daily TQ for 7 days starting from the first day after the operation. Thymoquinone was administered as a single dose oral gavage through a 4F feeding catheter per each day. The bursting strength of the anastomosis was measured on 3rd and 7th postoperative days (POD) and resection was performed. Subsequently, the hydroxyproline level in the resected tissue was measured and a histological evaluation was performed.

Results: The bursting pressures of the anastomoses were measured to be statistically significantly greater on 7th POD in TQ administered groups compared to those without TQ administration. Tissues were stained with Masson's trichrome dye in order to evaluate the amount of fibrous tissue reaction for histopathological examination; there was no significant difference in the amount of fibrous tissue between groups 1 and 2, while a very marked increase in the fibrous tissue was detected in groups 3 and 4. Mean tissue hydroxyproline levels of the groups 3 and 4 on 7th POD were 1.30 and 2.72 μg/g-protein, respectively. The difference between the groups was statistically significant (p = 0.001).

Conclusions: TQ significantly increased the bursting pressure of the anastomosis, tissue hydroxyproline level, and fibrous tissue production.
