Malachite green chloride (MGC) is a dye used to prevent fungus infections in commercial fisheries. Leucomalachite green (LG) is formed from MGC and remains in the tissues of exposed fish. Researchers studied the effects of MGC on female rats and female mice to identify potential toxic or cancer-related hazards to humans. The researchers conclude that tumors of the thyroid gland, liver, or mammary gland in female rats might have been caused by MGC, but that MGC did not cause cancer in female mice. They conclude that LG might have caused cancers of the thyroid gland in male and female rats, and of the testes in male rats and liver in female rats. LG caused an increase in cancer of the liver in female mice. Charts and graphs.

Description: The taxonomic status of the two commercially important cupped oysters, Crassostrea angulata, the Portuguese oyster (Lamarck, 1819) and Crassostrea gigas, the Japanese oyster (Thunberg, 1793) has long been in question. The recent observation of the hybridization between C. gigas and C. angulata and the production of fertile F1s led us to search for cytogenetic evidence of both parental genomes in the interspecific hybrids. The cytogenetic characterization of the hybrids was performed by the use of restriction endonuclease treatments. This technique has recently shown the potential for individual chromosome identification by banding in oysters. Chromosomes of C. gigas, C. angulata and their hybrids were treated with two different restriction enzymes (ApaI and HaeIII), stained with Giemsa, and examined for banding patterns. These chromosome markers allowed the parental haploid sets to be identified in the hybrids. The analysis of the banded karyotypes of the interspecific hybrids showed that for each chromosome pair, one of the homologues presented a banding pattern consistent with that of C. gigas and the other homologue presented a banding pattern consistent with that of C. angulata. These cytogenetic results substantiate the reported interspecific hybridization between C. gigas and C. angulata. In view of these results and taking into account the present expansion of C. gigas aquaculture in southern Europe, the question of the need for preservation of pure C. angulata stocks should be raised as only a few populations remain in the south of Spain and Portugal. Recently, changes in the genetic composition of populations in southern Portugal have indeed been observed, showing that human activities have created contact zones between the two taxa while no natural sympatric zones exist in Europe.

Anthraquinone is used as an intermediate in the manufacture of dyes and pigments, an additive in the kraft pulping process in the paper industry, a catalyst in the isomerization of vegetable oils, an accelerator in nickel electroplating, and as a bird repellent. The Nat. Toxicology Program (NTP) studied anthraquinone to determine if it caused cancer in rats or mice. They conclude that anthraquinone caused cancer of the kidney and urinary bladder in male and female rats and of the liver in female rates. The occurrence of some liver tumors in male rats may have been related to anthraquinone exposure. The NTP concludes that anthraquinone caused liver cancer in male and female mice, and thyroid gland tumors in mice may have been related to anthraquinone. Illus
