[Knowledge of schistosomiasis in traditional Chinese medicine].

Schistosomiasis is a modern disease name, but it has been widespread in ancient China and exists in a specific form in traditional Chinese medicine (TCM) . The purpose of the paper is to make clear the existing form of schistosomiasis in TCM and infer the prevalence of schistosomiasis in ancient China. The paper focuses on the period when great progress was made on schistosomiasis by TCM, and sums up the understanding of TCM toward schistosomiasis in this period. By studying and analyzing the literature of schistosomiasis in this period, the paper tries to find out the representative Chinese medicine symptom description and TCM "other name" of schistosomiasis, so as to accurately judge whether the relevant description in ancient TCM books and historical documents can provide scientific basis for schistosomiasis. It is important to understand the prevalence and cognition of schistosomiasis in ancient China.

[Removal of weremit from the abdomen. Interpretation and efficacy of an ancient Egyptian prescription by the newest scientific results]. / A weremit kiuzése a hasból. Óegyiptomi recept hatásosságának értelmezése az újabb kutatási eredmények alapján.

Significant percentage of today's knowledge of ancient Egyptian medicine has been acquired from papyri left behind from various periods of Egyptian history. The longest and the most comprehensive is the Ebers papyrus, kept at the University Museum of Leipzig, which was written more than one thousand years before Hippocrates (c. 460-377 BC). One of the riddles among the prescriptions of the Ebers papyrus Eb20 has been used in order to remove the so called "wemyt" weremit from the abdomen with the help of a drink, which consists of "jnnk", Conyza dioscoridis in milk or sweet beer. The authors assume that the disease could be an infection of Schistosoma haematobium and/or Schistosoma mansoni. Nowadays the tea of Conyza dioscoridis is widely used as an important part of traditional medicine against rheumatism, intestinal distention and cramps, as well as an antiperspirant, and with external use for wound healing. The authors' intent is to interpret the efficacy of the above-mentioned ancient prescription with the help of modern medical and pharmaceutical knowledge.

The origin and dispersion of human parasitic diseases in the old world (Africa, Europe and Madagascar).

The ancestors of present-day man (Homo sapiens sapiens) appeared in East Africa some three and a half million years ago (Australopithecs), and then migrated to Europe, Asia, and later to the Americas, thus beginning the differentiation process. The passage from nomadic to sedentary life took place in the Middle East in around 8000 BC. Wars, spontaneous migrations and forced migrations (slave trade) led to enormous mixtures of populations in Europe and Africa and favoured the spread of numerous parasitic diseases with specific strains according to geographic area. The three human plasmodia (Plasmodium falciparum, P. vivax, and P. malariae) were imported from Africa into the Mediterranean region with the first human migrations, but it was the Neolithic revolution (sedentarisation, irrigation, population increase) which brought about actual foci for malaria. The reservoir for Leishmania infantum and L. donovani--the dog--has been domesticated for thousands of years. Wild rodents as reservoirs of L. major have also long been in contact with man and probably were imported from tropical Africa across the Sahara. L. tropica, by contrast, followed the migrations of man, its only reservoir. L. infantum and L. donovani spread with man and his dogs from West Africa. Likewise, for thousands of years, the dog has played an important role in the spread and the endemic character of hydatidosis through sheep (in Europe and North Africa) and dromadary (in the Sahara and North Africa). Schistosoma haematobium and S. mansoni have existed since prehistoric times in populations living in or passing through the Sahara. These populations then transported them to countries of Northern Africa where the specific, intermediary hosts were already present. Madagascar was inhabited by populations of Indonesian origin who imported lymphatic filariosis across the Indian Ocean (possibly of African origin since the Indonesian sailors had spent time on the African coast before reaching Madagascar). Migrants coming from Africa and Arabia brought with them the two African forms of bilharziosis: S. haematobium and S. mansoni.
