Selected Publications
Acute Toxicity Study
To determine LD50, MTD or NOEL of test compounds and to determine the doses for repeated dose studies
Sub-acute Toxicity Study
To determine the repeated dose toxicity of test compounds and also the doses for chronic studies
Sub-chronic Toxicity Study
To establish NOEL, to identify and characterize the specific organs affected after repeated dosing and predict the appropriate dose for chronic toxicity studies
Chronic Toxicity Study
To establish to identify the cumulative toxicity, carcinogenic potential of the test compound and characterize the specific organs affected after repeated dosing
AMES:
Biological assay to assess the mutagenic potential of chemical compounds.
Test system includes Salmonella typhimurium TA98 and/or TA100 using 6 concentrations of the test substance in the absence of metabolic activation
Potential solvents include: USP Water for Injection (WFI), USP 0.9% Sodium Chloride for Injection (NaCl), Dimethylsulfoxide (DMSO), Acetone, 95% Ethanol (EtOH), and Cottonseed Oil.
Micronucleus Test:
To assess the potential of a test material to induce genetic damage in vivo and determine toxicity
An Initial range finding study is performed using a maximum dose of 2,000-mg/kg body weight followed by four lower concentrations of the test substance using rodents
End points observed are signs of toxicity, loss of weight, clinical symptoms of toxicity, alteration of ratio of immature to mature red blood cells in the bone marrow and clastogenicity is measured as the proportion of micronucleated erythrocytes
Bone marrow smears are prepared after 24 and 48 hours of treatment. The treatment groups consist of negative, test, and positive control groups. The bone marrow smears are examined to count approximately 2,000 immature and a corresponding number of mature erythrocytes per animal in each group.
Potential solvents include: USP 0.9% Sodium Chloride for Injection (NaCl) and Cottonseed Oil.
Chromosomal Aberration Assay:
To assess the potential of a test material to induce genetic damage in vivo and determine toxicity
The cells are exposed to the test substance at three concentrations in the presence and absence of metabolic activation
The duration of study is TK+/- mouse lymphoma or CHO HGPRT mutation assay: 14 - 18 days
Test system includes rodents, mammalian-cells
Potential solvents include: Ham’s F12, Dimethylsulfoxide (DMSO), and 95% Ethanol (EtOH)
Irritation and Sensitization
To determine the potential of a test material to provoke ocular, dermal irritation, or sensitization
The duration of study for Irritation - one hour to two weeks after a single topical or corneal administration, Sensitization – intra dermal or topical induction doses followed by topical challenges with a non-irritating dose
Endpoints include degree of erythema, edema, pruritis, papules, vesicles, corneal irritation, swelling, microscopic integrity of corneal endothelium, other features of the eye (conjuctive, cornea, iris, lens, opthalmascopy)
AJES toxicology Studies are designed for the evaluation of toxicity of test articles. These studies may be preliminary investigations/ early toxicology for internal review or for regulatory submissions and direct extrapolation to human safety.
Regulatory Guidelines:
AJES toxicology studies are designed as per major international guidelines applicable. Some of these include OECD, US FDA, EPA, EMEA, ICH, EC, ISO or USP.
Test Systems:
AJES offers testing services in rodents and non human primates.
