Methods for the Collection of Venoms
نویسنده
چکیده
Despite the early recognition (see Chapter 1) of the dangerous nature of the venom of bees, wasps and ants, it was the end of the nineteenth century before venoms started to attract the attention of medical research workers. A prerequisite to studies on the nature of the venoms was the development of methods for their collection. Before collection of venom could be possible, the Hymenoptera must be collected in the field or reared in or near the laboratory. Social Hymenoptera usually can be collected in the field in large quantities or reared near the laboratory (honey-bees). Solitary wasps must be one by one collected in the field or reared in the laboratory. A number of solitary wasps cannot be reared in the laboratory in large quantities, often because of complicated mating behaviour. For example, Simonthomas and Poorter (1972) studied the mating behaviour of the digger wasp Philanthus triangulum (Fig. 1) and found that the male must have a large territory, which could hardly be built in the laboratory. Since P. triangulum is used for the study of its venom (see Chapter 5) and mating failed in the laboratory, a large number of wasps have been collected in the field. This is possible when a population of this wasp reaches a large density, as has happened several times in the twentieth century in Europe, and recently also in Egypt (Simonthomas and Simonthomas, 1980).

Background: Poisoning due to the bites and stings of venomous snakes and scorpions is a neglected public health problem, particularly in rural areas. Poor health facilities and inadequate knowledge of health care personnel are the major factors that result in envenomated human victims not receiving adequate care and medical attention. There is a great need for up-to-date and effective healthcar...

In this study, Mesobuthus gibbosus and Mesobuthus eupeus eupeus venom samples were compared for lethality, in vivo effects and proteins. Neutralization capacity of monovalent Androctonus crassicauda antivenom (RSHA anti-Ac) was tested against the lethal effects of the venoms.Venom was obtained from mature scorpions by electrical stimulation of the telson. The lethality of the venom and potency ...

Platelet aggregation inhibitory effect and anticoagulant properties of fractions separated from the venoms of Cerastes persicus fieldi and Echis carinatus were investigated. The partial fractionation was performed on a Sephadex G-100 column. Two fractions separated from Cerastes persicus fieldi showed anti platelet aggregation activity on ADP (200 µM)-induced platelet aggregation (ca 80% inhibi...
