Despite the important role of Metalloproteinase (MMP) in β-cellular matrix remodeling there is clearly not enough data concerning the MMP proteolytic activity during first three weeks (early scar changes) of postoperative gastric ulcers. Thus the main aim of our work was the MMP, TIMP-1 and bFGF overall activity determination as well as their role in post-burn wound healing in case of the 2 nd degree esophagus acid burn infliction. The greatest increase in the metalloproteinase activity and bFGF level was observed at 21 st d of our experiment. In addition, the greatest increase in the TIMP-1 level in the esophageal mucosal was observed at 7 th d after burn. These changes may be an evidence of chronic inflammatory processes and scar changes in rat esophagus after the EAB infliction.
Under malignant growth, the alterations of blood serum biochemical parameters including activity of studied enzymes were observed. The drug “Grinization GRIN R” was shown to stabilize the tumor growth of Guerin’s carcinoma as well as biochemical parameters in the range close to normal values. The changes of protein metabolism parameters appeared to be significant. Also the considerable changes of AST and ALT activities were demonstrated. In the case, there was significant difference between the groups studied (р<0.05). Administration of rats with drug “Grinization Grin R” in different doses led to decreasing of average tumor volume in dynamics. Increasing and normalization of total protein level in rats with Guerin’s carcinoma was established under “Grinization GRIN” administration in doses 115 mg/kg and 270 mg/kg. The meaning of albumin concentration approached to physiological normal value under “Grinization GRIN” administration in dose 270 mg/kg. Meanwhile AST and ALT activities were approaching to normal values in rats with Guerin’s carcinoma under “Grinization GRIN” administration in dose 270 mg/kg. Such effects were observed mainly at the 18th and 23th days after tumor inoculation in comparison with tumor control (Guerin's carcinoma) values.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
