In each male, the following testicular lesions were scored: (1) hemocytic infiltration of the gonadal acini and phagocytosis of spermatogenic cells, (2) hemocytic infiltration of interacinal connective tissue, (3) aggregations of hemocytes under the mantle epithelium, and (4) occurrence of brown cells.
For example: a long exposure refers to a single, protracted shutter cycle to capture enough low-intensity light, whereas a multiple exposure involves a series of relatively brief shutter cycles; effectively layering a series of photographs in one image.
Acute toxicity describes the adverse effects of a substance that result either from a single exposure or from multiple exposures in a short period of time (usually less than 24 hours). To be described as acute toxicity, the adverse effects should occur within 14 days of the administration of the substance. Acute toxicity is distinguished from chronic toxicity, which describes the adverse health effects from repeated exposures, often at lower levels, to a substance over a longer time period (months or years).
