A 67-year-old Caucasian male with lung cancer was presented to the Emergency Department with asthenia, anorexia, jaundice and choluria. The patient's lung cancer was being treated medically by a combination of paclitaxel/carboplatin with bi-monthly frequency. The patient was also self-medicating with several natural products, including Chlorella (520 mg/day), Silybum marianum (total of 13.5 mg silymarin/day),...
Ciguatoxins (CTXs) are fish metabolism products and a result of biotransformation of precursor gambiertoxins produced, in the first instance, by benthic dinoflagellates Gambierdiscus and Fukuyoa. Ciguatoxins are potent neurotoxins that selectively open voltage gated sodium channels in excitable cells causing the human food poisoning known as Ciguatera (CFP). Endemic from tropical areas in central...
During current research, the effects of deoxynivalenol (DON) exposure on cerebral lipid peroxidation, neurotransmitter secretion and calcium homeostasis in chicks were evaluated. One hundred and twenty Hailan chicks (male, 1-day-old) were randomly divided into four groups. Chicks in low, medium and high dose groups were fed with 0.27, 1.68 and 12.21 mg/kg−1 DON respectively by gavage according to...
The consequences of scorpion stings on the affected victims, including humans, have been known since ancient times. The effects of the venom, first on neurotransmission and thereafter on many physiological processes at the organism, tissue, cellular or molecular levels, have been the subject of intense research. It is, therefore, not surprising that a large number of toxins acting on a variety of...
MCLR has been shown to act as potent hepatotoxin, and recent studies showed that MCs can accumulate in lung tissue and exert adverse effects. However, the exact mechanism still remain unclear. The present study mainly focuses on the impairments of respiratory system after MCLR exposure in mice. After intratracheal instillation with MCLR (0, 10 and 25 μg/kg bw), histological change was examined in...
Snake venom phospholipase A2 (PLA2) has widely been reported to possess antibacterial effects, and PLA2 is the major component of cottonmouth snake venoms. We assessed the antibacterial activities of crude venoms from Western cottonmouth (Agkistrodon piscivorus leucostoma), Eastern cottonmouth (Agkistrodon piscivorus piscivorus), and Florida cottonmouth (Agkistrodon piscivorus conanti) snakes against...
This case report describes a dog envenomed by a red-bellied black snake (RBBS; Pseudechis porphriacus) that experienced severe and life-threatening haemolysis. The dog presented with hypersalivation, facial swelling, mildly prolonged activated clotting time and the absence of neurological deficits. Envenomation was confirmed by positive identification of the snake and retrospective measurement of...
In fjord systems, Harmful Algal Blooms (HABs) not only constitute a serious problem when affecting the wildlife and ecosystems, but also human health and economic activities related to the marine environment. This is mostly due to a broad spectrum of toxic compounds produced by several members of the phytoplankton. Nevertheless, a deep coverage of the taxonomic diversity and composition of phytoplankton...
In the American continent, larval forms (caterpillars) of the Lonomia genus can cause systemic reactions in human beings. In this Paper, we report the third case of Lonomia envenoming recorded in French Guiana in 25 years, and the first in which specific antivenom was administered. Severe symptoms of the envenoming were observed in our patient including pain; coagulopathy and systemic hemorrhage....
A 51-year-old man presented with rapid onset encephalopathy and respiratory failure after a suspected intravascular envenomation from a North American pit viper. The patient received antivenom and was transferred to a tertiary care facility where he had cardiovascular collapse and persistent coagulopathy requiring 28 vials of Crotalidae polyvalent immune Fab antivenom for initial control and six vials...
Acute kidney injury (AKI) is one of the most important complications of bothropic poisoning and its early identification remains challenging. The nephrotoxicity of Bothrops insularis venom (BinsV) was previously described by our research group. In this study, we continued to evaluate the effect of BinsV on kidney function in mice and LLC-MK2 proximal tubule cells, evaluating KIM-1 protein as an early...
A study was conducted to determine the effects of zearalenone (ZEN) on the mRNA expression of pregnane X receptor (PXR), constitutive and rostane receptor (CAR), and phase I and II enzymes as well as the toxicity in the liver of female weanling piglets. Thirty-two female weanling piglets (Duroc × Landrace × Large white, 12.27 ± 0.30 kg)were divided into four groups (n = 8 piglets/group) that were...
