| Mitochondrial DNA (mtDNA) has been widely employed in phylogeographic and phylogenetic studies. In the present study, the genetic identification of the scorpion Androctonus crassicauda (Olivier, 1807) was carried out by using the 16S mitochondrial gene, since this scorpion represents the most important species in Turkey regarding scorpionism and antivenom production. Two genetic groups were found according to the sequence analysis results, while five different loci at the nucleotide level presented genetic variation in the 16S region when compared to a known A. crassicauda sequence data (GenBank, AJ277598). Nucleotide variations found in the current work constitute the first descriptive report for A. crassicauda. Moreover, future studies may enlighten the... |

| Scorpion envenomation remains a real health problem in many countries. In scorpionism cases, it is often recommended that patients be treated with species-specific antivenom. Androctonus crassicauda venom has been used as antigen for antivenom production in Turkey, where this antivenom, called Turkish antivenom, has also been effective in the treatment of envenomation caused by species other than A. crassicauda. The present study aimed at determining the paraspecific effects and potency of the Turkish antivenom against Mesobuthus gibbosus (Brullé, 1832) venom. To assess the venom toxicity and the antivenom efficacy, we determined the Minimum Lethal Dose (MLD) and the Minimum Effective Dose (MED) instead of LD50 and ED50, respectively. Androctonus... |

| Scorpions are venomous arthropods of the Arachnida class and are considered relatives of spiders, ticks and mites. There is not any study about the biochemical effects of Androctonus crassicauda (Olivier, 1807) venom. Therefore, in the present study, we aimed at evaluating the toxicity of the venom from A. crassicauda, which is responsible for a number of deaths of infants, children and adults in tropical and subtropical countries. For this purpose, rats (n=35) were divided into seven groups of five animals each; venom solutions (250µg/kg) were subcutaneously injected into rats; blood samples were taken from each animal at various times; and serum biochemical parameters were measured (levels of total proteins, total bilirubin, albumin, globulin, urea,... |

| Scorpions can be considered living fossils because they have changed so little during the last 400 million years. They are venomous arthropods of the Arachnida class and regarded as relatives of spiders, ticks and mites. The aim of the present study was to evaluate the toxicity of Androctonus crassicauda (Olivier, 1807) venom and its effects on the acetylcholinesterase (AchE) activity and on electrolytes levels in rats. Animals were divided into seven groups of five rats each. Test groups received 250µg/kg of venom solution while control group was treated with 200µl of physiological saline solution (PSS). Blood samples were collected from the animals on the 1st, 2nd 4th, 8th, 12th, and 24th hours after subcutaneous injection of venom. Animals were... |

| The present study was carried out to produce highly efficient antivenom from a small number of telsons in a short time. Venom solution was prepared through maceration of telsons from Androctonus crassicauda (Olivier, 1807) collected in the Southeastern Anatolia Region, Turkey. Lethal dose 50% (LD50) of the venom solution injected into mice was 1 ml/kg (95% confidence interval; 0.8-1.3), according to probit analysis. Different adjuvants (Freund's Complete Adjuvant, Freund's Incomplete Adjuvant, and 0.4% aluminium phosphate), at increasing doses and combined with venom, were subcutaneously injected into horses on days 0, 14, 21, 28, 35, and 42 of the experiment. Antivenom was collected from the immunized horses on days 45, 48, and 51 using the pepsin... |

| The aim of the present study was to analyze the parametric values of Androctonus crassicauda (Oliver, 1807), the most significant scorpion species in Turkey. For this purpose, 11 male and 11 female A. crassicauda specimens were collected from Sanliurfa region. The body parts most important for species identification were measured by using sensitive calipers. Differences between sexes were statistically significant for pectinal organ length (female: 7.50±1.26mm;male: 8.63±1.05mm; p=0.033), pectinal tooth count (female: 25.36±0.86;male: 33.36±0.80; p=0.000), and carapace width (female: 10.27±1.19mm;male: 9.09±0.73mm; p=0.000). However, body length (female: 90.09±14.74mm;male: 82.95±5.40mm), abdomen width (female: 12.09±1.90mm;male: 11.09±0.88mm), and... |
