Abstract CO2-insufflation and electrocoagulation were advanced as causative factors of postsurgical adhesions. We assumed that severe tissue reaction due to electrocoagulation might obscure CO2-insufflation impact on adhesion formation. Therefore, the purpose of this study was to evaluate the effects and interactions of surgical trauma and CO2-insufflation on adhesion formation. Prospective-randomized study with 60 rats, equally divided into 3 groups. In the control group, the sidewall adhesion model was induced by monopolar coagulation of the uterine horn and ipsilateral parietal peritoneum and by mechanical damaging - in the opposite side through open laparoscopy without CO2-insufflation. In two other groups, CO2 was insufflated for 60 min at 15 cm of water, either before or after the sidewall model-induction. Parameters of sidewall and lesion site adhesions of parietal peritoneum and uterine horns were evaluated by scoring system and analyzed by two-way ANOVA with Bonferroni posttests, one-way ANOVA Student-Newman-Keuls multiple comparisons test, as well as by two-tailed unpaired Mann-Whitney test. Monopolar coagulation significantly increased peritoneal lesion site adhesion scores, as compared with the scores for mechanical damaging (p=0.0001). Visceral peritoneal lesion sites were more predisposed to adhesion formation than parietal peritoneal lesion sites (p=0.0009), whereas CO2 did not affect parameters of either sidewall or peritoneal lesion site adhesions, regardless of the insufflation mode (p>0.05). The data suggest that both surgical trauma and peritoneal lesion sites had a substantial impact on adhesion formation, whereas CO2 did not interfere with adhesion parameters irrespective of its insufflation mode. These findings may improve our insights into adhesion formation pathophysiology and open new perspectives in developing future adhesion prevention strategies.

    Classically, the 3’untranslated region (3’UTR) is that region in eukaryotic protein-coding genes from the translation termination codon to the polyA signal. It is transcribed as an integral part of the mRNA encoded by the gene. However, there exists another kind of RNA, which consists of the 3’UTR alone, without all other elements in mRNA such as 5’UTR and coding region. The importance of independent 3’UTR RNA (referred as I3’UTR) was prompted by results of artificially introducing such RNA species into malignant mammalian cells. Since 1991, we found that the middle part of the 3’UTR of the human nuclear factor for interleukin-6 (NF-IL6) or C/EBP gene exerted tumor suppression effect in vivo. Our subsequent studies showed that transfection of C/EBP 3’UTR led to down-regulation of several genes favorable for malignancy and to up-regulation of some genes favorable for phenotypic reversion. Also, it was shown that the sequences near the termini of the C/EBP 3’UTR were important for its tumor suppression activity. Then, the C/EBP 3’UTR was found to directly inhibit the phosphorylation activity of protein kinase CPKC in SMMC-7721, a hepatocarcinoma cell line. Recently, an AU-rich region in the C/EBP 3’UTR was found also to be responsible for its tumor suppression. Recently we have also found evidence that the independent C/EBP 3’UTR RNA is actually exists in human tissues, such as fetal liver and heart, pregnant uterus, senescent fibroblasts etc. Through 1990’s to 2000’s, world scientists found several 3’UTR RNAs that functioned as artificial independent RNAs in cancer cells and resulted in tumor suppression. Interestingly, majority of genes for these RNAs have promoter-like structures in their 3’UTR regions, although the existence of their transcribed products as independent 3’UTR RNAs is still to be confirmed. Our studies indicate that the independent 3’UTR RNA is a novel non-coding RNA species whose function should be the regulation not of the expression of their original mRNA, but of some essential life activities of the cell as a whole.
