“…Studies with T . catappa extract usually used extraction at room temperature (Claudiano et al, 2009, 2012), but hot extraction promoted higher content of active compounds (Jeyaseelan, & Jashothan, 2012; Meneses et al, 2020); then, the difference observed in the present study in vitro reflected the greater efficacy of the hot extract on the mycelium of S . parasitica .…”

The oomycete Saprolegnia sp. infects freshwater fish, resulting in mortality and economic loss in fish farms (Shaalan et al., 2018). This pathogen affects fish in all development stages, from eggs to adults.It damages the chorionic membrane of eggs, quickly infecting all spawning and killing viable eggs (Liu et al., 2014). Pterophyllum scalare is among the fish species that are sensitive to this disease (Eissa et al., 2013).Currently, few chemical products are legal to control fungal disease in Brazilian aquaculture, although some chemotherapy drugs have been used such as malachite green, iodopovidone, formalin,

“…A lower concentration of EGCG 12 mg/l and 1 g/l of C-PC showed lesser lamellar fusion and hyperplasia compared to the high dosage, slight epithelial lifting was observed, and inflicting much greater harm. Cytoplasmic vacuole and necrosis in the cell in juvenile fish Colossoma macropomum were reported when testing the acute toxicity of a hot aqueous extract from Terminalia catappa leaves similarly cellular hypertrophy [25] , atrophy, cytoplasmic vacuolation, and necrosis were found in common carp subjected to chlorpyrifos [26] . Cytoplasmic vacuolation and dilation of the sinusoid space were observed in zebrafish when subjected to Silver oxide (Ag 2 O) and Silver carbonate (Ag 2 CO 3 ) doped Titanium dioxide (TiO 2 ) nanoparticles and pure TiO 2 particles [27] .…”

Acute Toxicity of Epigallocatechin Gallate and C-Phycocyanin in ZebrafishEpigallocatechin gallate and C-phycocyanin are natural food supplements, gaining a lot of popularity in biomedical researches. The lethal concentration 50 value for the zebrafish model was determined using a 96 h semi-static acute toxicity test. Zebrafish were transferred into a 1 l water tank starting with a minimal dose of 8 mg of epigallocatechin gallate and 1 g of C-phycocyanin, which further increased to the concentration of 30 mg for epigallocatechin gallate and 5 g for C-phycocyanin. Lethal concentration 50 of epigallocatechin gallate and C-phycocyanin was calculated to be 21.37 mg/l and 2.45 g/l respectively at 96 h in the zebrafish model. At high doses above 12 mg of epigallocatechin gallate and 1 g of C-phycocyanin, the test fish displayed various behavior responses like erratic and jerky swimming, attempts to jump out of the water, frequent surfacing and swallowing of air, normal skin color change, decreased opercular movement and finally leading to death. Histological observations showed hypertrophy, atrophy and vacuolar degeneration in the liver whereas tubular degeneration, glomerular hyper cellularity, dilation of Bowman's space, hemorrhage, and necrosis were observed in the kidneys exposed to the high doses of epigallocatechin gallate and C-phycocyanin treated fish. The gills of the test animals also expressed lamellar synechiae, hyperplasia, curling of lamellae, mucus secretion and shortening of the secondary lamella. The results demonstrated that doses above 30 mg/l and 5 g/l in the case of epigallocatechin gallate and C-phycocyanin respectively gave 100 % mortality and expressed organ-specific toxicity. Overall results revealed that exposure to high concentrations of epigallocatechin gallate and C-phycocyanin uninterruptedly may lead to severe alterations in the tissue of experimental animals.
