The rate of diffusion through the non-aqueous layer of the protoplasm depends largely on the partition coefficients mentioned above. Since these cannot be determined we have employed an artificial system in which chloroform is used in place of the non-aqueous layer of the protoplasm. The partition coefficients may be roughly determined by shaking up the aqueous solutions with chloroform and ana...

Rosa damascena (Rosaceae) has been found to act on central nervous system including the brain. Several studies confirm that Rosa damascena inhibits the reactivity of the hypothalamus and pituitary systems in rat and can suppress the reactivity of central nervous system. In traditional medicine the hypnotic effect of rose is also suggested. In the present study hypnotic effect of ethanolic, aque...

objective: the beneficial effects of clove on toothache have been well documented. we have also previously shown the analgesic effects of clove essential oil. the present work was done to investigate the analgesic effects of the aqueous extract of clove using hot plate test. the possible role of opioid receptors in the analgesic effects of clove was also investigated using naloxone. materials a...

purpose:  to determine whether angiotensin ii levels in aqueous humor is related to diabetes mellitus and to evaluate the effect of captopril. methods: in a case-control study, aqueous humor samples were obtained during cataract surgery from 58 eyes of 58 patients, of which 37 were diabetic. from these latter subjects, 16 had taken captopril (captopril group) and 21 had not taken any angiotensi...

Humor is hypothesized to be a social activity that alters the status of the humorist positively and that of the object or victim negatively. Of the two traditionally distingushed classes of humor, "ostracizing" humor singles out a victim, with others present or absent either incidental affiliates of the humorist (and one another) or unaffected. "AltBiative" humor, on the other hand, is focused ...

Mineral paragenesis of rodingitized basic rocks of Iranian ophiolites are presented and metasomatic reactions between Ca+2 bearing aqueous fluids issued during serpentinization of host ultramafic rock – with magmatic minerals of basic rocks leading to present paragenesis of rodingites are discussed. It is concluded that Ca+2 rich aqueous fluid in equilibrium with serpentinite has high Ca+2 chem...

In this paper, in terms of the concentration of an aqueous solution of a surfactant, we investigate the self-assembly behavior of a porphyrin, 5, 10, 15, 20-tetra(4-pyridyl)-21H, 23H-porphine [H2TPyP], by using an oil/water system as the medium. We find that when a chloroform solution of H2TPyP is dropwise added into an aqueous solution of cetyltrimethylammonium bromide [CTAB] with a lower conc...
