Myocardial infarction is a common presentation of coronary artery disease and the leading cause of death worldwide. The present study was investigated potential resistance to ischemia-reperfusion (I/R) injuries following administration of methanolic (MeOH) extract of Scrophularia frigida (S. frigida) in isolated rat heart. Male Wistar rat hearts (n= 8-10) were isolated and allowed to equilibrat...

Seven species of Opostegidae are reported from the Himalaya:Opostegoides pelorrhoa (Meyrick, 1915), Pseudopostega frigida (Meyrick, 1906), P. nepalensis Puplesis & Robinson, 1999, P. zelopa (Meyrick, 1905), Pseudopostega brevicaudata Remeikis & Stonis, sp. nov., Opostega chalcophylla Meyrick, 1910 and one documented but left unnamed Opostegoides species. Genital structures of all species treate...

BACKGROUND A prospective, randomized, placebo-controlled clinical trial was conducted to compare the healing effectiveness of Alkanna tinctoria (L.) Tausch (Boraginaceae) with standard dressing on wound healing at the donor site after removal of the skin graft. METHODS Enrolled patients were randomly allocated to receive topicalA. tinctoria extract ointment (20%) or standard dressing (dressin...

Lithospermum erythrorhizon cell cultures have been used to produce plant secondary metabolites, as well as in biosynthetic studies. Shikonin, a representative secondary metabolite of L. erythrorhizon, was first produced industrially by dedifferentiated cell cultures in the 1980s. This culture system has since been used in research on various plant secondary metabolites. Other boraginaceaeous pl...

An Alkanna orientalis leaf and flower extract inhibited the growth of Staphylococcus aureus, a pathogen that causes an estimated 478 000 hospitalizations in the US annually. Bioassay-guided fractionation of A. orientalis resulted in isolation of the flavonoid sarothrin (5,7,4'-trihydroxy-3,6,8-trimethoxyflavone), which inhibited the growth of Mycobacterium smegmatis (MIC 75 µM) and S. aureus (M...
