Opis:: The leaf extracts of two medicinal plants Asystasia gangetica (L) and Newboulia leavis (p. Beauv) were assessed for anti-snake venom activity in vivo using mice. The result of the phytochemical analysis revealed that the two plants contain flavonoids, glycosides, saponins, tannins and alkaloids. The methanolic extracts of the two plants A. gangetica (L) and N. leavis (p. Beauv) significantly (p< 0.05) neutralized the Naja melanoleuca venom-induced lethality activity in the mice. The extracts (flavonoids, tannins and saponins) of the two plants also showed significant (p<0.05) neutralization of the venom–induced lethality activity in mice. The work confirmed that Asystasia gangetica and Newbouldia leavis possess significant anti-venom activity and can therefore be used in the treatment of snake bites.

Opis:: Introduction. The Vipera berus (common viper) is the only species of venomous snake found in Poland. The aim of this study was to determine to what extent coagulopathy has occurred as a post-bite complication. Materials and method. The medical records of 138 adult patients in the Sucha Beskidzka hospital with the diagnosis of snake bite between 2001–2014 were retrospectively analyzed. Demographic, clinical and laboratory data were collected. Antivenom was given to all patients, except one, with snake bites, but laboratory test were taken prior to administration of antivenom. Obtained results were compared to those of the control group, composed of 176 adults hospitalized in the same period for an elective laparoscopic cholecystectomy. Results. The mean platelet count in the study group was 239.94×109/L (SD=56.56) and 248.77×109/L (SD=57.82) in the control group. In 98% of the study group and 100% of the control group the platelet value (PLT) fell within laboratory norms (130 to 420×109/L), 2 patients after snake bites had a PLT lower than normal, and thrombocytosis was not observed in either group. A reference range of 0.85–1.3 INR below normal was found in 2 patients in the study group and 15 from the control group, while values above the normal range were found in 8 patients (6.7%) from the snake bite group and no patients from the control group. In the study group, the INR ranged from 0.78–1.43 with a mean of 1.046 (SD=0.14), while in the control group the range was from 0.79–1.28, with a mean of 0.95 (SD=0.08). There was a significant difference in INR between the study and control groups (p<0.0001). Conclusions. The bite from V. berus does not result in severe thrombocytopenia, with only a moderate increase in INR values observed in about 7% of patients.

Opis:: Many snake venoms comprise different factors, which can either promote or inhibit the blood coagulation pathway. Coagulation disorders and hemorrhage belong to the most prominent features of bites of the many vipers. A number of these factors interact with components of the human blood coagulation. This study is focused on the effect of Echis carinatus snake venom on blood coagulation pathway. Anticoagulant factors were purified from the Iranian Echis carinatus venom by two steps: gel filtration (Sephadex G-75) and ion-exchange (DEAE-Sephadex) chromatography, in order to study the anticoagulant effect of crude venom and their fractions. The prothrombin time was estimated on human plasma for each fraction. Our results showed that protrombin time value was increase from 13.4 s to 170 s for F2C and to 280 s for F2D. Our study showed that these fractions of the venom delay the prothrombine time and thus can be considered as anticoagulant factors. They were shown to exhibit proteolytic activity. The molecular weights of these anticoagulants (F2C, F2D) were estimated by SDS/PAGE electrophoresis. F2C comprises two protein bands with molecular weights of 50 and 79 kDa and F2D a single band with a molecular weight of 42 kDa.
