Cardiomyopathy Following Latrodectus Envenomation

Latrodectus envenomations are common throughout the United States and the world. While many envenomations can result in catecholamine release with resultant hypertension and tachycardia, myocarditis is very rare. We describe a case of a 22-year-old male who sustained a Latrodectus envenomation complicated by cardiomyopathy.

Wound Healing Activities of Rafflesia Hasseltii Extract in Rats

The effects of topical application of Rafflesia hasseltii buds and flowers extract on the rate of wound healing and histology of healed wound were assessed. Four groups of adult male Sprague Dawley rats were experimentally wounded in the posterior neck area. A thin layer of blank placebo was applied topically to wounds of Group 1 rats. Wounds of experimental animals (Group 2 and 3) were treated...
