An average of five people die annually in Finland of injuries caused by domestic animals. During the years 1957–68 the greatest number of deaths (30) was caused by horses, then by cows (18), and bulls (11). Dogs had killed 2 people and a cat and ram 1 person each. None of these deaths was a result of bites. Poisonous animals caused 22 deaths during the years 1936–68. Out of these 22, 20 were snake bites (the last one in 1961) and 2 were wasp stings (the last one in 1959). In 1969, a very unusual death was caused by pigs in Turku. A farmer was found dead in the pigsty among 12 pigs. He had lain there for about six hours. The autopsy showed that he had suffered from severe aortic stenosis. The viscera showed signs of cardiac failure. The pigs had gnawed the soft parts of the face, the eyes, all organs of the neck, and the genitals. Biochemical determination of histamine and serotonin proved that the wounds had been caused before death. Organs of the abdominal cavity had also been crushed. Bites and marks of pigs' feet were observed all over the body. Most likely, the man had fallen into the pigsty because of a heart attack. He had obviously been unable to move and was possibly unconscious when the pigs had savaged him.

No Campus da Universidade Federal de Lavras, MG, a estação de inverno é marcada por temperaturas e umidade relativa do ar baixas, e um por longo período seco. Neste período, um grande número de incêndios oriundos das comunidades vizinhas atinge o campus, particularmente as áreas de difícil acesso, o que prejudica o controle e uso de equipamentos básicos. O objetivo deste trabalho foi descrever a origem, causas e formas de controle dos incêndios. A metodologia utilizada foi o Diagnóstico Rápido Participativo – DRP, por meio de 12 entrevistas semi-estruturadas. Concluiu-se que não são realizadas queimadas controladas; houve aumento dos números de incêndios decorrentes da expansão urbana; há falta de manutenção dos aceiros e estradas; os maiores responsáveis são incendiários juvenis. Os principais problemas decorrentes dos incêndios relacionam-se ao abastecimento de água, toxidez da fumaça e presença de animais peçonhentos nas residências. O combate inicial é realizado pelos moradores locais. PARTICIPATORY RAPID APPRAISAL IN THE RESEARCHING OF THE CAUSES OF FIRES AT UFLA´S CAMPUS Abstract The winter season in the campus of the Federal University of Lavras, Lavras, Brazil, is characterized by lower temperatures and air humidity, and a long period of drought. During this period a high number of fires arising from the neighborhoods reach the campus, particularly those areas with more difficult access, bringing additional difficulties to fire control and use of basic equipments. The objective of this work was to describe the origin, causes and forms of fire control. The method used was the Participatory Rapid Appraisal – FPD, through 12 semi-structured interviews. The conclusions were that controlled fires are not carried out; there was an increase of the number fires resulting from urban expansion; there was a lack of maintenance of both fire-breaks and roads; the main responsible were young arsoners. The main problems arising from the fires are related to water supplying, smoke toxicity and the presence of the poisonous animals in residences. The initial combat is carried out by local inhabitants.

Generally speaking, tongue inflammation occurs quite frequently, especially the types of tongue that are worth depending on: a) Injuries (burns from hot food, acids, and from corrosive liquids and spices, splinters, stinging bees, wasps, coats from fruits and honey in the mouth), b) strong poisonous animals (biting off the heads of poisonous snakes by magicians, as well as snacking on random anthrax toads) and c) general poisoning (for rye, smallpox, scarlet, typhoid, pyemia, uremia and mercury).

This paper gives a brief outline of inherited links between various instruments. In doing so, attention is given to their spread and transformation process from an ancient Egyptian sistrum to a different type of a stick rattle1, also known as xi-stick or xízhàng in Chinese. This instrument once existed during the middle ages. In the process of time however, its use was witnessed in the Uyghur’s’ sabayi, the sachi and further to the Vietnamese sinh tien and the Japanese suzu. These instruments can create a rapid succession of rattling and complex sounds, some of which simulating frogs croaking during tropical rainy seasons. Other sounds imitate the repeated thrum of rattlesnakes searching for a spouse. Depending on time and place, the former are linked with praying for rain and the latter with reproduction. Thus, the rattles this study discusses are, among others, used in prayers for fertility and rain, peace and safety, healing rituals (curing diseases), for longevity. Furthermore, these rattles are sounded to ward off evil spirits, exorcise plagues and to keep poisonous animals away. All these resemble the mythological connotation to the copulating of Fuxi and Nuwa. Hence, they belong to the specific worldviews closely connected with the importance of reproduction in early times of humankind. They all involve fertility, death, reincarnation, eternal life, and the function of triggering trance, in which people seem to feel connected with heaven and earth, deities or ancestors.

Leeches are amazing animals that can be classified as conditionally poisonous animals since the salivary cocktail they produce is injected directly into the victim, and its components have strictly defined biological purposes, such as preventing blood clot formation. Thrombolytic drugs are mainly aimed at treating newly formed blood clots. Aged clots are stabilized by a large number of isopeptide bonds that prevent the action of thrombolytics. These bonds are destroyed by destabilase, an enzyme of the leech’s salivary glands. Here, we conducted a pilot study to evaluate the feasibility and effectiveness of the use of destabilase in relation to blood clots formed during real pathological processes. We evaluated the isopeptidase activity of destabilase during the formation of a stabilized fibrin clot. We showed that destabilase does not affect the internal and external coagulation cascades. We calculated the dose–response curve and tested the ability of destabilase to destroy isopeptide bonds in natural blood clots. The effect of aged and fresh clots dissolving ability after treatment with destabilase coincided with the morphological characteristics of clots during surgery. Thus, recombinant destabilase can be considered as a potential drug for the treatment of aged clots, which are difficult to treat with known thrombolytics.
