“…The oral treatment was most effective and was able to prevent or delay the onset of lesions in a sustained manner. Additionally, after oral, i. p., or topical application, titers of a parasite-specific antibody (IgG) were reduced to 20 % when compared with untreated mice [84]. Interestingly, the activity was abolished in vitro and in vivo by cotreatment with N-monomethylarginine, an inhibitor of inducible NO synthase and, hence, of NO production.…”

“…Antiparasitic (anti-leishmania), antibacterial, hepatoprotective and immunomodulatory activities have been described for Kp leaf extracts (Da Silva et al 1995;Akinpelu, 2000;Muñoz et al 2000;Yadav and Dixit, 2003;Rossi-Bergmann et al 1994;Almeida et al, 2000). Exploratory toxicological studies in mice and humans have indicated absence of chronic and acute oral toxicity (Torres-Santos et al, 2003, Sousa et al, 2005.…”

“…Despite the early reports on the antihistaminic activity of Kp using the experimental models of isolated guinea pig ileum contraction and vasodilatation in rats (Nassis et al, 1992); its fatty acid associated suppressive activity on T cells (Rossi-Bergmann et al, 1994, Almeida et al, 2000. ), and its Th2-suppressive and iNOSsuppressive association with oral protection against cutaneous and visceral leishmaniasis (Da-Silva et al, 1995, Da-Silva et al, 1999, Gomes et al 2009), only recently the therapeutic effect of Kp in allergy was more deeply explored. The antianaphylactic activity o Kp was studied using a murine model of OVA-induced anaphylactic shock.…”

“…Oral treatment with leaf extract significantly delayed onset of disease in BALB/c mice infected with Leishmania amazonensis as compared to untreated mice or mice receiving K. pinnata by the intravenous or topical routes 6 . Potent cytotoxic compounds bersaldegenin-1, 3, 5-orthoacetate 7 and bufadienolide-bryophyllin B 8 were isolated.…”
