Adult ovariectomised rats were divided into six groups and injected either with vehicle or a single dose of oestradiol , a selective ER alpha agonist - PPT [ 4 , 4 ' , 4 '' - ( 4 - propyl - [ 1H ] - pyrazole - 1 , 3 , 5 - triyl ) trisphenol ] , a selective ER beta agonist - DPN [ 2 , 3 - bis ( 4 - hydroxyphenyl ) - propionitrile ] , a selective ER alpha antagonist - MPP [ 1 , 3 - bis ( 4 - hydroxyphenyl ) - 4 - methyl - 5 - [ 4 - ( 2 - piperidinylethoxy ) phenol ] - 1H - pyrazole dihydrochloride ] or a selective ER beta antagonist - PHTPP ( 4 - [ 2 - phenyl - 5 , 7 - bis ( trifluoromethyl ) pyrazolo [ 1 , 5 - a ] pyrimidin - 3 - yl ] phenol ) .
