Trypanosomiasis is caused by a pathogenic protozoan of the genus Trypanosoma, being Trypanosoma vivax the most important agent for cattle. The aim of the present study was to demonstrate the expansion of T. vivax infection in different mesoregions of Minas Gerais, Brazil, and describe the clinicopathological findings of trypanosomiasis in cattle. The diagnosis was based on visualization of the parasite in blood smears and DNA detection of T. vivax in the blood of live cows and tissues of necropsied animals by the polymerase chain reaction (PCR). Thirty suspected herds were tested, of which 11 were positive for T. vivax. The most frequent clinical signs were anemia, apathy, drop in milk production, weight loss, reproductive disorders, and nervous signs. Concomitant diseases, such as malignant edema, pneumonia and increased cases of mastitis were associated with T. vivax infection. Three cows were necropsied and the most significant findings were low body condition score, pale mucous and spleen with white pulp hyperplasia. The results demonstrated the expansion of T. vivax infection in Minas Gerais, that PCR-associated blood smears are promising for diagnosis, and that other diseases often occur concomitantly to T. vivax infection in regions with trypanosomiasis in cattle.

Objectives : Herbal medicines have been used a lot traditionally in Northeast Asia. In particular, various Apiaceae plants (Umbelliferae) are widely used for medicinal purposes among countries. However, the original species designated in each pharmacopoeia standards, are sometimes different and confuse. In this study, herbal medicines in the pharmacopoeia were analyzed for Apiaceae taxa to compare the taxonomic identity and different taxonomic opinions for each country based on their local flora and recent taxonomic studies. Methods : The scientific names of herbal medicines were analyzed origins from Pharmacopoeias of Republic of Korea, Democratic People's Republic of Korea, People's Republic of China, Taiwan, and Japan. Especially, we compared their local floras, international plant scientific name database, and recently published taxonomic studies to confirm the correct scientific name. Results : The analyzed apiaceous herbal medicines in pharmacopoeias were all 21 items and 39 taxa; the highest percentage, genus Angelica (21%) and roots including rhizomes (62%) the registered genera and medicinal parts, respectively. Eleven items were in all five country's pharmacopoeias. Four items were in more than two countries' pharmacopoeias. Six items were registered in only one pharmacopoeia. Conclusions : Our research provides necessary information, e.g., corrected scientific names of original species based on taxonomic species concepts, taxonomic reviews, and figures of medicines. These results will help in the understanding of the apiaceous taxa among the five countries' pharmacopoeias. Moreover, these extensive nomenclatural reviews of authentic apiaceous taxa will help for the next revision of Korea Pharmacopoeia.
