    Aim: In this study, we aim to investigate the effects of supplementary Grape Seed Extract (GSE) and Low-Level Laser Therapy (LLLT)on fracture healing, oxidant and anti-oxidant system in experimental mandible fractures.Materials and Methods: 48 Wistar Albino rats (adult male, n=48) were used in our study. For all the subjects, a vertical fracture linethrough molar teeth in right mandibles was created and internally fixed using a four-hole microplate and four micro screws. Firstly,these subjects were randomly divided into 4 main groups (Control, GSE, LLLT, GSE+LLLLT) of 12 animals each, and then these wereindividually separated into two sub-groups of 7th and 21st days. The number of groups (n=6) was 8 in total. GSE of 300 mg/kg/day were provided to the subjects before they were sacrificed. LLLT of 23 J/cm2 was administered to two different points alongwith the fracture line at intervals of 48 hours for 7 days in the 7th day sub-groups and for 14 days in the 21st day sub-groups. Afterthe procedure, while biochemical values such as TAS, TOS and OSI are measured; histopathologically it was examined in termsof capillary number and width, inflammatory cell, fibroblast count, collagen fibers, osteoblast count, ossification and mature boneformations.Results: For biochemical analyses, there was statistically significant difference only in TAS values on either the 7th or 21st day forthe groups. Histological analyses showed that mandibular fracture healing were significantly better in the GSE and GSE+LLLT groupscompared to the control group. The group of only LLLT had limited recovery while the combination of GSE+LLLT was the best forossification.Conclusions: It is concluded that GSE may be one of the potential methods to accelerate fracture healings in mandibular fracturescommon in oral and maxillofacial surgery clinic and thus help patients recover in shorter time, and however LLLT can have positiveeffects on the process of ossification and recovery only when combined with the extract, which may result in better outcomes inclinical use.

    Potential Cardiogenic Effects of Poisonous Mushrooms
    (2021) Sevindik, Mustafa; Özaltun, Betül; Braidy, Nady; Akgül, Hasan; Akata, Ilgaz; Selamoğlu, Zeliha
    Natural resources have been the savior of people at every stage of human history. Mushrooms are very valuable food sources, especially in the rainy seasons. They can be grouped as poisonous, edible or inedible, depending on their nutritional status. These groups have positive or negative effects. Some types of mushrooms have different medicinal properties thanks to their bioactive compounds. It is necessary to characterize their toxicological profiles, especially before using mushroom species for human consumption, as toxic substances are identified even in some edible species. Mycetism, known as mushroom poisoning, is an international health problem. There are those that cause deadly poisoning and limited symptoms of poisoning in mushrooms. Poisonous mushrooms are divided into many classes as cytotoxic, neurotoxic, myotoxic, gastroirritan mushrooms according to their types or symptoms they cause. It is known that mushroom poisoning can cause serious toxicity on the liver, kidneys and central nervous system. However, its effect on heart function has not been determined yet. This study focused on poisonous mushrooms and their cardiological effects.
