[Objective] The study aimed to research the effect of carbonate-alkalinity on growth and development Bufo garfarizans tadpole and provide data and reference for the adaptability of other aquatic organism growth to carbonate-alkalinity.

Micro-nuclear test and the alkaline single-cell gel electrophoresis assay(SCGE) or comet assay was performed to examine the genotoxicity of butachlor onerythrocytes of Bufo gargarizans gargarizans tadpoles exposed to increasing concentrationof the tested substance(0.

We study the effects of the phthalate esters on China toad tadpoles micronucleus.

Objective To investigate the spatiotemporal patterns and age-related changes of expression of type Ⅰ and type Ⅳ collagen in the corneal development of Bufo raddei larvae during metamorphosis.

Using the technology of immunohistochemical staining and color image analysis to investigate the spatiotemporal pattern and age_related changes of type Ⅰ collagen expression in the corneal development of Bufo raddei larvae during metamorphosis.

150 0 mg/L) of cadmium on Bufo raddei tadpole development showed that each treatment could shorten the time for 50% tadpoles' hatching, but have no effect on the hatching rate.
