Toxicon 2025; 255:108263.

Abstract
Tityus serrulatus accident promote vast symptomatology related to toxins of the venom, which leads to a massive release of neurotransmitters, notably dopamine, affecting behavior and neurochemistry. The recommended treatment for envenomation is the antiscorpionic serum (SAEsc) administration. Related to this complexity of the Tityus serrulatus envenomation, this study aimed to assess organism responses to the venom, its impact on behavior, oxidative stress, neurochemistry, and genetic impacts, as well as the efficacy of SAEsc, especially concerning dopamine levels and genetic interactions. Swiss mice were divided into groups and administered different venom concentrations intracerebroventricularly to assess behavioral impacts and brain oxidative stress. Oxidative stress was evaluated through reactive oxygen species (ROS) analysis and antioxidant assays, including dichloro-dihydro-fluorescein diacetate (DCF), thiobarbituric acid reactive substances (TBARS), superoxide dismutase (SOD), and glutathione (GSH) measurements. Swiss mice were divided into four groups to evaluate genomic modulation, micronucleus enhancement, and dopamine levels. Additionally, SAEsc's neutralizing effect on dopamine was also investigated. Results showed that venom doses (100-300 ng/μL) increased lipid peroxidation in the brain, with SAEsc maintaining dopamine balance and neutralizing venom up to 24 h post-envenomation. After 24 h, cellular repair became less efficient, leading to mutagenic damage in both treated and untreated animals. The results highlight the importance of considering genomic and neurotransmitter function modulation in the treatment of Tityus serrulatus envenomation.

Renal Alterations Induced by the Venom of Colombian Scorpion Centruroides Margaritatus. Curr Top Med Chem 2019; 19:2049-2057.

Abstract
BACKGROUND Scorpion venom causes renal injury and affects vascular ion-channels function. Centruroides margaritatus scorpion is found in Colombia and is frequently the cause of envenomation accidents; however, its renal impact has never been investigated. OBJECTIVE To evaluate the effects of C. margaritatus venom (CmV) on renal parameters using isolated rat kidney and renal cell culture models. METHODS Wistar rats (n = 5, weighing 240-300 g) were first perfused with Krebs-Henseleit solution containing 6 g 100 mL-1 bovine serum albumin. After 30 minutes, the kidneys were perfused with CmV to a final concentration of 10 μgmL-1; evaluation was performed by measuring Perfusion Pressure (PP), Renal Vascular Resistance (RVR), Urinary Flow (UF), Glomerular Filtration Rate (GFR), and percentage of electrolyte tubular transport. Moreover, kidney histological analyses and cell cytotoxicity in renal tubule epithelial cells (MDCK) and proximal tubular cells (LLC-MK2) were assessed. RESULTS CmV increased PP and RVR 60 min after perfusion. On the other hand, UF, GFR, and the percentages of sodium, potassium and chloride tubular transport decreased after experimental envenomation. UF dropped after 120 min, while GFR and percentage of electrolyte tubular transport diminished after 60, 90 and 120 min. CmV was not toxic to MDCK cell line but reduced the viability of LLC-MK2 cells at concentrations ranging from 6.25 to 200 μgmL-1. Histological analyses disclosed hydropic degeneration, edema, and protein deposits. Flow cytometry disclosed that cell death occurred predominantly by necrosis. CONCLUSION Our results suggest that C. margaritatus venom can trigger renal impairment, mainly in the proximal kidney tubule.

Protective effect of aqueous extract, fractions and phenolic compounds of Hancornia speciosa fruits on the inflammatory damage in the lungs of mice induced by Tityus serrulatus envenomation. Toxicon 2019; 164:1-9. [PMID: 30902683 DOI: 10.1016/j.toxicon.2019.03.018] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2018] [Revised: 03/13/2019] [Accepted: 03/17/2019] [Indexed: 01/13/2023]
Abstract
Scorpion envenomation has been considered a public health issue around the world. Tityus serrulatus represents a specie of major medical importance in Brazil due to mortality rates of approximately 1% among children and elderly populations. The aim of this work was to evaluate the in vivo anti-inflammatory potential of aqueous extract from Hancornia speciosa fruits, its fractions and its phenolic compounds against T. serrulatus envenomation. After receiving the T. serrulatus venom (TsV, 0.8 mg/kg) intraperitoneally, the animals were treated intravenously with the aqueous extract (20, 30 and 40 mg/kg), the arachnid antivenom (50 μL/animal), the dichloromethane, ethyl acetate and n-butanol fractions (20 mg/kg) as well as rutin and chlorogenic acid (2, 2.5 and 5 mg/kg). The treatment with the aqueous extract, fractions and phenolic compounds decreased the migration of leukocytes to the peritoneal cavity and reduced the levels of IL-1β, IL-6 and IL-12. Moreover, the pulmonary histopathologic analysis showed a reduction in both interstitial and alveolar edema, as well as in the leukocytes infiltration and vascular ectasia in the mice's lungs, which evidences a protective effect attributed to H. speciosa. This is the first study that demonstrates the inhibitory potential of the aqueous extract from H. speciosa fruits against inflammation induced by TsV. These findings suggest that the bioactive compounds from the aqueous extract, especially chlorogenic acid and rutin, are responsible for the reported anti-inflammatory activity of H. speciosa.

ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2018; 243:661-669.

Abstract
Due to frequent detection in environment as well as in the human body, the adverse effects of decabromodiphenyl ether (BDE209) have been extensively studied in the past few years. However, information regarding the inhalation toxicity of BDE209 to humans is currently limited. In this study, the cytotoxicity, cell damage, and inflammation markers including IL-6, IL-8, and TNF-α in the Beas-2B cell line induced by BDE209 were measured using a central composite design. Results showed that as BDE209 concentrations (5-65 μg mL-1) and exposure time (6-30 h) were increased, cell viability sharply decreased from 99.7% to 29.7% and LDH activity increased from 0.1% to 13.1%. Furthermore, expression of IL-6, IL-8 and TNF-α transcripts were enhanced from 4.7 to 29.1 fold, 3.4-68.9 fold, and 2.8-47.0 fold, respectively, and the concentration of IL-6 and IL-8 proteins increased from 5.4 to 16.7 pg mL-1 and 71.0-550.0 pg mL-1, respectively. Results indicate that BDE209 exposure can inhibit cell viability, increase LDH leakage, and upregulate the transcript (mRNA) and protein levels of inflammatory markers of IL-6 and IL-8 in Beas-2B cells. Moreover, these effects were both dose- and time-dependent, and dose and time had a synergistic effect - enhancing toxicity when in combination. Cell density affected both LDH activity and IL-8 release but had little effect on cell activity and IL-6 release in the Beas-2B cells. In contrast, TNF-α protein was not detected but its mRNA expression level was upregulated. This study will provide a reference for human health risk assessment, especially for the toxic damage that BDE209 exposure can elicit in the respiratory tract.

Abstract
Tityus serrulatus is the scorpion associated with the most severe cases of scorpion envenoming in Brazil. However, there are no studies reporting the genotoxic effects of this venom in natural or experimental envenomations. It is well known that DNA-damage responses are providing opportunities for improving disease detection and management. In this study was evaluating the genotoxicity of the T. serrulatus venom in different organs (hippocampus, cortex, striatum, blood, heart, lung, liver and kidney) and periods in mice experimentally envenomed. ELISA and the Comet assays were used to quantification of venoms antigens and DNA damage, respectively. Forty-eight Swiss mice were divided into five groups and 0.5 DL50 of T. serrulatus venom (0.90 mg/kg) was administered intraperitoneally in each animal. Euthanasia was performed by cervical dislocation in the period of 0h (control group) 1h, 2h, 6h and 12h, where it the tissues were removed. The results showed high DNA damage in all structures analyzed, suggesting that T. serrulatus venom presented genotoxic activity or some secondary effect generated by venom injection. In the ELISA test, toxic circulant antigens were verified in practically all organs at the time intervals analyzed. Therefore, the distribution of the venom changes from organ to organ. We conclude that scorpion envenoming affects DNA in all organs analyzed even when the venom concentration is lower or no detectable, DNA damage persists.
