Thin Sheets

The outer chorioid (suprachorioid) of the eye of the toadfish Opsanus is a yellow argenteum which consists of two thin sheets. The inner one contains thin flat crystals of uric acid. The uric acid content is about 40 μg/cm2 of chorioid surface. The outer sheet contains yellow, birefringent granules, as yet uncharacterized. In conjunction with certain features of the retina, the yellow chorioid is responsible for eyeshine in the photopic eye.

Abstract Seven samples of naturally insect-infested wheat were examined for (a) uric acid content, (b) per cent agricultural damage, (c) whole or equivalent insects, and (d) insect damage as determined by X-ray technique. Thirteen different forms of flours obtained by milling these wheat grains in a Buhler pilot mill were analyzed for uric acid and insect fragment counts. For wheat grains, the correlation between uric acid contents and X-ray data was found to be the best among the six possible intercomparisons. The results for the first break flour samples also indicated good correlation between the uric acid levels and insect fragment counts.

Abstract Liquid chromatography is used to measure the uric acid content of wheat internally infested by various growth stages of granary weevil (Sitophilus granarius), rice weevil (Sitophilus oryzae), and lesser grain borer (Ryzopertha dominica). Good correlation exists between numbers of insects and uric acid content of grain infested by a given stage of an internally infesting stored product insect, with correlation coefficients ranging from 0.970 to 0.998. Uric acid content of infested grain increases as the insect life cycle progresses, with granary weevil producing the greatest quantities of uric acid followed in order by rice weevil and lesser grain borer. A detection limit for the analytical procedure of less than 1.0 ppm uric acid allows detection of infestation levels as low as one kernel per 100 g grain for late instar granary weevil larvae. This limit is sufficiently sensitive to detect levels of infestation that may be commonly encountered in commerce.

Thiourea Treatment

SUMMARY Following the observation that large daily doses of thiourea induced numerous mitoses in the liver of rats [Rachmilewitz, Rosin & Doljanski, 1950], the concomitant chemical changes in the liver and urine of thiourea-treated rats were investigated. It was found that: (1) The mitogenetic reaction, which occurred on the 3rd day of treatment with the drug, was preceded by (a) a decrease in liver catalase activity to 30–50% of the normal within 12 hr; (b) an increase in total liver weight and concentration of liver ribonucleic acid within 2 days. The enlarged liver was normal with respect to protein, lipid, water and deoxyribonucleic acid content. (2) The concentration of liver glycogen decreased markedly on the 1st day of thiourea treatment but returned to normal by the 2nd or 3rd day. (3) During the period of treatment with thiourea there was an increase in the urinary excretion of uric acid, allantoin, and phosphate, as well as glucosuria and polyuria. There was no change in the excretion of urea and total sulphate. (4) All these changes, both in the liver and the urine, were fully reversible on withdrawing the drug.
