Prom. 1965, 103~8(Russ). Rabbits of 1.5-2.2 kg. body wt. received, by stomach tube, 2.5 ml. dioxane (I) in aq. soln./kg. body wt., followed by repeat higher I doses if there were no clin. symptoms of intoxication, and their blood nonprotein N (NPN) detd. colorimetrically. When the NPN reached 300 mg. %, the animals were sacrificed by decapitation, the kidney cortex comminuted on ice, and the respiratory performance of the pulp, as well as its deamination performance towards DL-a-alanine, detd. following 1-hr. incubation at 37.5 in a Warburg app. and NHj and pyruvate formed in the filtrate were analyzed. Micro-" scopic lesions present at both levels of cuprizone feeding were confined to the central nervous system and consisted of edema, most prominent in the cerebellar cortex, and a noninflammatory demyelination. Edema was, however, also observed in the cere bellar medulla and midbrain. Hydrocephalus and cerebral edema occurred in mice fed cuprizone at a level of 0.5% of the diet. Supplementation of the 0.5% cuprizone diet with 25, 50, or 100 ppm. Cu did not alter significantly the neural lesions induced by the chelator. Only cuprizone feeding interrupted pregnancy. Pregnant mice fed 0.5% and 0.3% cuprizone from the 3rd day of pregnancy failed to deliver young. The former level resulted in a high percentage of nonviable young when scopic examn. of the kidneys revealed a pronounced picture of hydropic nephrosis, with a partial necrosis of the epithelium of the convoluted tubules. In severe cases of I intoxication with high NPN, the O consumption fell to .50% the CO2 forma tion to 37%, the NHj formation to 13%, and the pyruvate to 33% fold, of healthy kidney tissue, while in mild cases, the resp. figures showed only slight deviations from normal. feeding was started on the 9th day of gestation. A level of 0.1% cuprizone did not affect pregnancy when fed from the 3rd or 9th day of gestation. A Cu supplement of 130 ppm. increased the no. of viable young when added to the 0.5% cuprizone diet and fed from the 9th day of gestation, but no young were produced when feeding began on the 3rd day of gestation.

The blood of 35 patients with ethylene chloride (I) or CCl* poisoning was analyzed on the 2nd4th day following exposure and subsequently at 2-3 day intervals for a no. of constituents indicative of liver or kidney involvement. In most of the mild cases of poisoning, the bilirubin and aldolase increased slightly, the albumin/globulin ratio dropped, while the phospholipids and cholesterol remained unchanged, all the indices returning to normal within 10 days In cases of CC1< muscle are of equal amplitude in the normal animal at the interstijnulus intervals employed, but, in the soman-poisoned animal, the response to the 2nd of the dual stimuli is impaired. The amplitude of the 2nd response is directly related to the time interval between the stimuli. Maximal effect on the dual re sponse is evident after a dose of 0.1 mg. of soman/kg.
