Adult male C57BL/6 J mice were exposed to cadmium 25 mg/L (as CdCl) in drinking water for 16 weeks. During this time, pain-related behaviors including hindpaw mechanical sensitivity and vertical rears were evaluated every four weeks.

Painful distal symmetrical polyneuropathy (DPN) is a frequent complication of type-2 diabetes mellitus (T2DM) that commonly presents as neuropathic pain and loss of skin nerve fibers. However, there are limited therapies to effectively treat DPN and many of the current animal models of T2DM-induced DPN do not appear to mirror the human disease. Thus, we validated a DPN mouse model induced by a cafeteria-style diet plus low-doses of streptozotocin (STZ).

Horses were used to produce monovalent hyperimmune sera against each of three venoms ( and ) and their neutralizing potency, expressed as Median Effective Dose (ED), was determined against the venoms of all five species. In terms of PLA and caseinolytic activities, all venoms are extremely homogeneous.

For the elucidation of the chemical constituents, the high-performance liquid chromatography method (HPLC) was used, and verification of the antioxidant activity was carried out using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical method. The cytoprotective effects of extracts were determined by exposure to hydrogen peroxide.

We previously described that the (Variety Orange) ethanolic extract (BxbO) has an anti-inflammatory effect; however, this action is not fully understood. In this study, the action of the BxbO extract on the secretion of inflammatory mediators in two experimental models, and , after LPS challenge was evaluated.

Aim Of The Study: In the present study the in vivo antinociceptive and anti-inflammatory effects of the Bougainvillea xbuttiana ethanolic extract have been studied in mice.
Materials And Methods: The phytochemical analysis was performed.
In this study, we investigated in groups of female BALB/c mice injected with Crotalus durissus terrificus venom (Cdt) the renal function based on creatinine clearance, percentage of fractional excretion cytokines and histological examination of renal tissue. Cdt caused renal alterations that induced proteinuria during the initial hours post-venom and reduced creatinine clearance 15 min. up to 2 hours post-venom administration.

Several functional events were analysed, such as: cytotoxicity, spreading, extent of phagocytosis, vacuole formation and changes of internal calcium concentration. Among the main results observed, when macrophages are subjected to the effects of soluble venom of Tityus serrulatus scorpion venom, a partially purified fraction (FII) or a pure toxin (Ts1), are an increment in the percentage of phagocytosis and vacuole formation, a decrement of the spreading ability, accompanied by oscillations of internal calcium concentration.
