A peptic ulcer is a stomach lesion. It is generally caused by malnutrition, the use of anti-inflammatory medications, and an imbalance between mucosal defense systems. In fishes, the lubricous substance that called mucus secreted from the skin, prevents the entry of microorganisms that can enter the body through the skin.

The aim of this study is to examine the protective effect of oxyresveratrol (OXY) against isoproterenol-induced myocardial infarction in rats, through routine biochemical parameters and oxidative stress parameters that show heart damage. Oxyresveratrol was administered by oral gavage at doses of 10 and 20 mg/kg, respectively, once a day for 5 days. On the fourth and fifth days, 180 mg/kg isoproterenol was administered intraperitoneally to the OXY treatment group and control groups.

Skin injuries, such as burns, can result in an open wound that can lead to the deterioration of the skin, which acts as a protective barrier against external agents, and can cause serious health problems. Pectin, a plant-derived polysaccharide, is a suitable candidate for wound care due to its gel-forming ability and biocompatibility. Pectin absorbs wound exudates to form a soft gel and is known for its strong anti-inflammatory efects.

Boron, an essential element for human, can be a key factor in wound healing. For this reason, in this study, role of boron products (boric acid and zinc borate) and boron product doped new synthesized graphene hydrogels was investigated for burn healing via in vitro viability-biocompatibility tests and microbiological analysis. It has been determined that boric acid and zinc borate are effective against microbial agents that are frequently seen in burns.

Aim: The aim of the present study was to compare pure Ca(OH)2, Ca(OH)2 + ibuprofen and Ca(OH)2 + ciprofloxacin in terms of postoperative pain and prostaglandin E2 (PGE2) level in previously treated teeth with periapical lesions.

Materials And Methods: Sixty-six patients were randomly assigned into 3 groups according to the intracanal medication (Ca(OH)2, Ca(OH)2 + ibuprofen and Ca(OH)2 + ciprofloxacin). After removing gutta-percha from the root canals, the PGE2 sample collection was obtained by introducing three sterile paper points into the root canals through the root apex (2 mm).

Objective: This study evaluated the effects of local vitamin C treatment on tissue advanced glycation end products (AGE), interleukin (IL)-6, 8-hydroxy-2-deoxyguanosine (8-OHdG), and matrix metalloproteinases (MMP)-8 in tissues; serum C-terminal telopeptide fragments (CTX); and alveolar bone loss (ABL) in rats.

Methodology: 35 male Sprague Dawley rats were divided equally into five groups: 1) control (C), 2) experimental periodontitis (P), 3) experimental diabetes (D), 4) experimental diabetes and experimental periodontitis (D + P), and 5) experimental diabetes-experimental periodontitis-locally applied vitamin C (D + P + LvitC). Diabetes was induced in rats with alloxan monohydrate, after which periodontitis was induced by ligature placement in the right mandibular first molar teeth for 11 days.
