Tamarindus indica (Fabaceae) have been using in traditional medicine to cure various diseases, including mental stress and anxiousness. The current study was aimed evaluate phytochemical analysis anxiolytic activity of flower extracts (n-Hexane, Ethyl acetate, Chloroform methanol) different animal models such as elevated plus-maze, mirror chamber, light/dark, hole board tests. had showed presen...
Nitrogen incorporation from red alder (Alnus rubra Bong.) into an Oregon upland mesic forest soil was studied by tracing the fate of 15N added as 15N-labeled alder leaf litter. The recovery of 15N in vegetation, litter, lightand heavy-fractions of the soil, the chloroform-labile (microbial biomass) pool, and the whole soil were investigated after a 21-month field incubation of the labeled litte...
A water-soluble fraction was isolated from delipidated cells of Mycobacterium bovis strain BCG by extraction with hot water. Chemical analyses revealed that the above fraction presumably consisted of a peptidoglycan containing 5-10% of nucleic acids. When it was injected into guinea pigs with Freund's incomplete adjuvant plus egg white albumin as antigen, an increase of circulating antibody was...
A microsomal fraction from rat liver was subfractionated into three rough endoplasmic reticulum fractions RIII, RII and RI, together with a smooth endoplasmic reticulum plus Golgi fraction. Cyclic nucleotide phosphodiesterase activity was found in all fractions. Subsequently it was shown that Golgi fractions were essentially devoid of cyclic AMP phosphodiesterase activity and the activity resid...
Standard Reference Material (SRM) 1849 Infant/Adult Nutritional Formula has been issued by the National Institute of Standards and Technology (NIST) as a replacement for SRM 1846 Infant Formula, issued in 1996. Extraction characteristics of SRM 1846 have changed over time, as have NIST's analytical capabilities. While certified mass fraction values were provided for five constituents in SRM 184...
A new type of displacement transducer for recording the calibrated left apexcardiogram (QLAC) has been evaluated in 69 normal subjects and 99 cardiac patients. Total displacement of QLAC (TD), its peak first derviative (peak dD/dt (t-peak dD/dt). A strong corretation exists between peak dD/dt and TD in normal subjects (r=0.95) and the deviation from the normal relationship allows a separation b...
