Traumatic brain injuries (TBIs) represent a problem of public health all over the world if we consider its incidence, mortality and the big social costs. The increase of road and train traffic, the development of industry, the growth of alcohol consumption, the emergence and increase of terrorist attacks have led to more frequent and severe TBIs. There were registered 3260 deaths at the Institute of Forensic Medicine in Craiova, Romania, between 2010 and 2014; they were the result of severe traumas, 622 (19.07%) being caused by TBIs. The most affected by TBIs were men (the men/women ratio was of 3/1) and the elderly, mainly in the rural area. The main risk factor was alcohol intake; about 44% of the deceased people were under alcohol influence. The forensic examination highlighted the severity of cerebral meningeal lesions, the most frequent being cerebral and vascular lesions. The histopathological and immunohistochemical examinations emphasized various microscopic changes in accordance with the severity of the trauma and the time passed from impact until death.

Background and Aims: Hyperforin (HY) is used to treat depression and skin irritation and has been shown a number of pharmacological activities. The literature does no cite data on changes that may occur in the body after HY intake (ethylene diammonium salt - EDS) in long-term administration. From this point of view, the present work is a key to determining the pharmacotoxicological profile of the HY-EDS, in long-term administration. Materials and Methods: In present research, the influence of toxic doses of HY-EDS was investigated on the biochemical serum parameters and the histopathological changes in internal organs on the experimental mice model. For acute toxicity determination, the HY-EDS was tested in doses of 2000-5000 mg/kg, administered once per day orally. For subacute toxicity, the HY-EDS was tested in three groups of mice, in doses of 50, 75 and 100 mg/kg/day, administered once daily, for 28 consecutive days. Results and Conclusions: As concern acute toxicity, a lethal effect has not occurred at any of the two tested doses and HY-EDS was classified as Class V toxic: median lethal dose (LD50) >5000 mg/kg, p.o. After 14 days of follow-up in acute toxicity, the experimental results showed a statistically significant increase of aspartate transaminase (AST) and alanine transaminase (ALT), compared to the control group. There were no changes in creatinine and serum glucose compared to the control group. After the administration of repeated doses, it was observed an increase of serum transaminases and alkaline phosphatase. Histological examination revealed that the liver injuries were in an initial stage, making them reversible in case of HY-EDS treatment discontinuation. There was no evidence of kidney damage to any of the doses of HY-EDS.
