The aim of this study was to determine the content of vitamin C in the liver of rats exposed to dimethoate or pyrantel embonate as well as co-intoxication with both agents. Investigations were carried out in two stages. At each stage, the rats were divided into three experimental groups (I-III) and a control (C) group. In the first stage, rats from group I were administered pyrantel embonate at a two-week interval at a dose of 1/2 LD50, while the animals from group II received dimethoate for 28 days at a dose of 1/25 LD50, and those from group III - both mentioned compounds in an identical manner as in groups I and II. In the second stage, the rats from group I received pyrantel embonate at a dose of 1/5 LD50 for 3 consecutive days, while the animals from group II received dimethoate at a dose of 1/10 LD50 for 5 consecutive days, and those from III received both compounds, but pyrantel was administered on day 3, 4 and 5 of dimethoate administration. The concentration of vitamin C after pyrantel embonate and dimethoate administration was influenced not only by doses of the compounds used but also by the manner of their application (single or co-administration). Dimethoate delivered at a dose of 1/25 LD50 evoked an increase in vitamin C concentration that was observed to continue up to the 14th day after the exposure, whereas when applied at a dose of 1/10 LD50 it increased the vitamin C level only at the 3rd hour. A considerable decrease in the vitamin C level was reported after pyrantel treatment at a dose of 1/5 LD50. In rats from groups where the compounds were co-administered, increased level of vitamin C was observed at both stages of the experiment only in the first period after intoxication, i.e. up to the 6th hour.
