Há 3 dias · Fatal dose. Lethal oral dose of LSD in humans is estimated at 100 mg, based on LD 50 and lethal blood concentrations observed in rodent studies. Tolerance. LSD shows significant tachyphylaxis, with tolerance developing 24 hours after administration.
Há 4 dias · Behavioral responses and toxicity tendencies were carefully observed for 2 hours after treatment. Deaths in each group within 24 hours were noted and the remaining animals were kept under close observation for a further 2 weeks for any signs of delayed toxicity. Using the Behrens-Karber method, the lethal dose (LD 50) was estimated. 21,22
Há 4 dias · The Median lethal dose (LD 50) of the extract was estimated to be higher than 5000 mg/kg orally. The animals treated with the extract showed a significant (p<0.05) decrease in blood glucose levels compared to the negative control. Blood glucose levels dropped below baseline in the animals treated with the highest dose (1500 mg/ kg) of the extract.

Há 3 dias · The similar experimental settings as mentioned in in vitro bioassay was followed to analyse the median lethal dose (LD 50) and median lethal time (LT 50). The LD 50 values were calculated at 7 days of entomopathogen inoculation and LT 50 values were calculated using 3 × 10 7 cfu/mL. The values of LD 50 and LT 50 were estimated by using Opstat ...
Há 3 dias · All doses of the extract resulted in statistically significant parasitemia suppression (P < 0.001) compared to both the negative and positive control mice. For in-vivo antimalarial studies, activity of an extract is classified as very good, good, or moderate if it suppresses parasitemia by ≥ 50% at respective dose levels of 100, 250, and 500 mg/kg (Tajbakhsh et al, 2021).
Há 5 dias · Briefly, serially diluted mAbs were incubated with 100 TCID 50 (50% tissue culture infective dose) of an influenza virus at 37 °C for 2 h, and 100 μL virus-mAb mixture was added to MDCK cells.
