Clastogenic effect of bracken fern on human lymphocytes
Bracken fern has a lot of side effects, especially bleeding disorders, which are mainly seen in large animals. This study evaluates the effect of dietary bracken farm on chromosomes of cattle and humans.

Ingestion of bracken fern (Pteridium aquilinum v. arachnoideum) is associated with digestive tract cancer in different regions of Japan, Venezuela and Brazil.

In view of reports that dietary bracken fern causes chromosomal instability in cattle, the clastogenic effect of bracken fern was investigated, in a preliminary study, in peripheral lymphocytes obtained from habitual consumers and a control group of nonconsumers, which were carefully investigated about cancer history or family cancer history, negative in both cases, using protocols comparable to those previously described in studies in cattle raised on bracken pastures.

Cytogenetic analysis showed significant increased levels of chromosomal abnormalities, such as chromatid breaks, in cultured peripheral lymphocytes of the consumer group.
There was no correlation with subjects, gender, smoking habits or alcohol consumption, and the only correlation was with prolonged exposure to dietary bracken.

SMALL ANIMAL PRACTICE

Punica granatum associated with hepatotoxicosis in cattlemembers
The ingestion of pomegranates was associated with the deaths of 9 of 35 young cattle; 8 were found dead without any prior clinical signs being noted and 1 animal was observed to be weak with pale‐pink mucous membranes. This case report describes also gross pathological and histopathological signs of the affected cattle and discusses the question which toxic principle was underlying in this case.
