Acute Oral Toxicity of Tetrodotoxin in Mice: Determination of Lethal Dose 50 (LD50) and No Observed Adverse Effect Level (NOAEL). [PDF]
Toxins (Basel), 2017 Tetrodotoxin (TTX) is starting to appear in molluscs from the European waters and is a hazard to seafood consumers. This toxin blocks sodium channels resulting in neuromuscular paralysis and even death. As a part of the risk assessment process leading to a safe seafood level for TTX, oral toxicity data are required. In this study, a 4-level Up and Down

Confidence limit calculation for antidotal potency ratio derived from lethal dose 50. [PDF]
World J Methodol, 2013 To describe confidence interval calculation for antidotal potency ratios using bootstrap method.We can easily adapt the nonparametric bootstrap method which was invented by Efron to construct confidence intervals in such situations like this. The bootstrap method is a resampling method in which the bootstrap samples are obtained by resampling from the ...

Acute Toxicity (Lethal Dose 50 Calculation): Medicine as a Life Saver or Destroyer
International Journal of Advance Research and Innovation, 2019 Lethal dose (LD 50) has been calculated. Different-testing methods have been used. The observed values have been plotted by Dose-Response against measured response and dose. Different LD value shows that all substances are poison. It depend on the amount of dose whether a substance is poison or remedy.

The acute lethal dose 50 (LD50) of caffeine in albino rats
Regulatory Toxicology and Pharmacology, 2016 An acute LD50 is a statistically derived amount of a substance that can be expected to cause death in 50% of the animals when given by a specified route as a single dose and the animals observed for a specified time period. Although conducting routine acute toxicity testing in rodents has been criticized, it can serve useful functions and also have ...

Listeria monocytogenes intragastric and intraperitoneal approximate 50% lethal doses for mice are comparable, but death occurs earlier by intragastric feeding [PDF]
Infection and Immunity, 1990 The intraperitoneal (i.p.) and intragastric (i.g.) mouse approximate 50% lethal dose values (ALD50S) were determined for 15 food and clinical isolates of Listeria monocytogenes. Although all strains gave i.g. ALD50S comparable to or less than their i.p. ALD50S, the i.g.
