Taohong Siwu Decoction (TSD) is a classic prescription in traditional Chinese medicine and is widely used to promote blood circulation to remove blood stasis. However, the effect mechanisms are not yet well understood. Here, a urinary metabolomic approach based on liquid chromatography coupled to quadrupole time-of-flight mass spectrometry (LC/Q-TOF-MS) was conducted to explore the changes in the endogenous metabolites and to assess the integral efficacy of TSD on acute blood stasis model rats. Then, parameters for hemorheology and coagulation functions were detected...

Veterinarians specializing in nondomestic species are faced with unique challenges regarding research and diagnostic capabilities given the wild and frequently dangerous nature of their patients. Standard diagnostic techniques used in small or large animal practice are not always possible due to anatomical constraints, size, tractability, or the inherent risk of anesthesia in highly valued, rare species. Diagnostic modalities that utilize simple, relatively noninvasive techniques show promise in evaluating nondomestic species and elucidating the pathophysiology behind poorly characterized disease processes in both wild and captive populations...

Rhabdophis lateralis, a colubrid snake distributed throughout the continent of Asia, has recently undergone taxonomic revisions. Previously, Rhabdophis lateralis was classified as a subspecies of R. tigrinus (Yamakagashi) until 2012, when several genetic differences were discovered which classified this snake as its own species. To elucidate the toxicity of venom from this poorly studied colubrid, various biological activities were compared between the venom from the two snake species. The components of their venom were compared by the elution profiles of reversed-phase HPLC and SDS-PAGE, and gel filtrated fractions were tested for effects on blood coagulation...
