  Distinct pathophysiological mechanisms of Heterometrus laoticus and Lychas mucronatus scorpion venoms on cardiovascular and renal functions Abstract Background:    Heterometrus laoticus and Lychas mucronatus are widely distributed in Southeast Asia, yet their pathophysiological effects of both venoms remain poorly characterized due to low human fatality rates. This study compared their venom compositions and acute cardiovascular and renal effects. Methods:   Anesthetized male New Zealand White rabbits were monitored for blood pressure (BP), heart rate (HR), and renal clearance following intravenous administration of crude venom (0.5 mg/kg). Venom components were identified via LC-MS/MS, and hematological/biochemical parameters were assessed. Results:    H. laoticus venom induced a rapid, transient hypotension ( p < 0.05), followed by a mild, prolonged hypotensive phase (up to 120 min). Conversely, L. mucronatus venom elicited a biphasic response: ...

Review of the wolf-spider genus Draposa Kronestedt, 2010 from China (Araneae, Lycosidae)

Abstract

The wolf-spider genus Draposa Kronestedt, 2010 in China is reviewed. A new combination is proposed: Draposa aciculifera (Chen, Song & Li, 2001), comb. nov. (ex. Pardosa C L. Koch, 1847). Pardosa shugangensis Yin, Bao & Peng, 1997 is synonymized with Draposa zhanjiangensis (Yin, Wang, Peng & Xie, 1995), syn. nov. Detailed redescriptions, habitus photographs, illustrations of copulatory organs, and live habitus images are provided for relevant species. Draposa burasantiensis (Tikader & Malhotra, 1976) is transferred back to Pardosa and figures of P. burasantiensis sensu Yin et al. (1997b) from China are provided.
