Schistosomiasis artesunate, or mefloquine. A Cochrane review found tentative evidence that when used alone, metrifonate was as effective as praziquantel. Another agent, mefloquine, which has previously been used to treat and prevent malaria, was recognised in 2008–2009 to be effective against "Schistosoma". Historically, antimony potassium tartrate remained the treatment of choice for schistosomiasis until the development of praziquantel in the 1980s. The disease is found in tropical countries in Africa, the Caribbean, eastern South America, Southeast Asia, and the Middle East. "S. mansoni" is found in parts of South America and the Caribbean, Africa, and the Middle East; "S. haematobium" in
Treatment of equine lameness cells may be harvested from other horses ahead of time to have banked for immediate treatment of an injury, but there is some concerns of graft-vs-host disease. Stem cells have been used to treat a variety of injuries in horses. The most research has been performed on stem cells used for treatment of tendon and meniscal injuries. Horses with tendonitis treated with bone marrow derived stem cells had a significantly lower re-injury rate compared to those without treatment. Stem cell treatment in damaged tendons is thought to improve the collagen make-up of the tendon while healing. It has been shown
