in an attempt to develop alternative medicine for the treatment of diabetes and related complications, the antidiabetic potential of the fruits of c rataegus pinnatifida was evaluated. the antidiabetic potential of the methanol (meoh) extract as well as different solvent soluble fractions of the fruits of c . pinnatifida was evaluated via α-glucosidase, protein tyrosine phosphatase 1b (ptp1b), ...

background: salvia mirzayanii, a native plant to iran, is shown to have immunomodulatory effects on lymphocyte proliferation. objective: to identify the bioactive immunomodulatory compound(s) present in s. mirzayanii. methods: the crude extract was fractionated to five fractions in two steps using different solvents. the fractions were subjected to bioassay-guided fractionation. all the fractio...

the effect of odonthobuthos doriae (o.d) scorpion venom at 0/3, 1 and 3, 10 µg/ml concentrations were investigated on nerve-muscle transmission, using the twitch tension technique. a concentration of 0.3 µg/ml caused a small change in the twitch height in response to indirect muscle stimulation, but higher concentrations (1, 3, 10 µg/ml) caused a transient augmentation in twitch response follow...

objective: radiation effects induced in non-irradiated cells are termed radiation-induced bystander effects (ribe). the present study intends to examine the ribe response of qu-db bystander cells to first, second and third radiation fractions and compare their cumulative outcome with an equal, single acute dose. materials and methods: this experimental study irradiated three groups of target ce...

   The aerial parts of Stachys laxa Boiss. and Buhse.from Siah-bishe in Mazandaran province, Stachys trinervis Aitch. and Hemsl. from Karaj in Alborz province, Stachys subaphylla Rech. F. and Stachys turcomanica Trautv. from Golestan province have been collected in May 2008. Total extracts were obtained through MeOH/H2O (80/20) and then partitioned between CHCl3, EtOAc and MeOH. These fractions...
