We report the first description studies, partial characterization, and intraspecific difference of Centruroides edwardsii, Gervais 1843, venom. C. edwardsii from two Colombian regions (Antioquia and Tolima) were evaluated. Both venoms showed hemolytic activity, possibly dependent of enzymatic active phospholipases, and neither coagulant nor proteolytic activities were observed. Venom electropho...

Viper’s venom is a source of biopharmaceutical compounds, hence the need to assess the effect of this animal extract on human blood. Here, we studied the blood coagulation disorders and hemolytic activities of the venom of M. bornmulleri viper. The pro-coagulant and anticoagulant effects are analyzed with venom concentrations ranging from 0.4 to 0.0031 mg/mL. Thus, the PT is way above the norma...

rheumatoid arthritis is an autoimmune disease that causes chronic inflammation of the joints as well as other organs in the body. adjuvant-induced arthritis models in inbred rats serve as relevant models for ra, having many clinical similarities to this disease. using honey bee venom as a treatment for rheumatoid arthritis is an ancient therapy in various parts of the world. however scorpion ve...

Background: One of the acute hematologic malignancies is acute promyelocytic leukemia (APL) that resulted in translocation of chromosomes 15 and 17, t (15; 17), and cessation in the maturation of myeloid cell line, and ultimate aggregation of neoplastic promyelocytes. Regarding that appetence of using herbal and marine medicine studies is increasing, and on the other hand, the features of Cassi...

Monotremes (echidna and platypus) are egg-laying mammals. One of their most unique characteristic is that males have venom/crural glands that are seasonally active. Male platypuses produce venom during the breeding season, delivered via spurs, to aid in competition against other males. Echidnas are not able to erect their spurs, but a milky secretion is produced by the gland during the breeding...

BACKGROUND Snake bite is a neglected public health problem in communities in rural areas of several countries. Bothrops jararaca causes many snake bites in Brazil and previous studies have demonstrated that the pharmacological activities displayed by its venom undergo a significant ontogenetic shift. Similarly, the venom proteome of B. jararaca exhibits a considerable variation upon neonate to ...

Bee venom acupuncture has been widely used in Oriental medicine with limited evidence of effectiveness. Most of the complications due to bee venom acupuncture are local or systemic allergic reactions. However, serious medical and neurological complications have also been reported. We herein describe the treatment of a 68-year-old woman who developed progressive quadriplegia 10 days after receiv...

Background:Envenomation by Macrovipera lebetina (M. lebetina) is characterized by prominent local tissue damage, hemorrhage, abnormalities in the blood coagulation system, necrosis, and edema. However, the main cause of death after a bite by M. lebetina has been attributed to acute renal failure (ARF). It is unclear whether the venom components have a direct or indirect action in causing ARF. T...
