Background and aims: Exposure to the normal hexane can induce dysfunction of the nervous system and color vision impairment. Occupational risk assessment is established according to no observed adverse effect levels (NOAEL). Recently, because of the NOAEL’s limitations, the benchmark responses were applied for risk assessment. The study’s aim is an analysis of benchmark response in occupational...
Background and Objective: For most of cancers there is no treatment and most of them ended in death. So, the first investigational stage is evaluation of toxic effects of drug fractions on cancer cells. Artemisia species are important medicinal plants throughout the world. In this study, anti-tumoral effects of seven Artemisia spp. fractions from Iran were studied on cancer and normal cells. Ma...
the present study was carried out to determine the hypoglycemic activity of the methanolic extract and solvent fractions (n-hexane and ethyl acetate) of ruellia tuberosa in normal and alloxan-induced diabetic rabbits. optimum dose of r. tuberosa for hypoglycemic activity was determined by oral administration of the methanolic extract (me) to normal and diabetic rabbits. diabetes was induced by ...
Normal hexane is adopted as a typical organic solvent for comparison with liquid water in modern theories of hydrophobic hydration, and detailed results are worked-out here for the C-atom density in contact with a hard-sphere solute, rhoCG(R), for the full range of solute radii. The intramolecular structure of an n-hexane molecule introduces qualitative changes in G(R) compared to scaled-partic...
I studied the spatial structure of the thick transition region between n-hexane and a colloidal solution of 7-nm silica particles by X-ray reflectivity and grazing incidence small-angle scattering. The interfacial structure is discussed in terms of a semiquantitative interface model wherein the potential gradient at the n-hexane/sol interface reflects the difference in the potentials of "image ...
The present study investigated the potential anticancer activity of the bark of Mangifera zeylanica, an endemic plant in Sri Lanka that has been traditionally used for cancer therapy. Cytotoxic and apoptotic effects were investigated in vitro using sulphorodamine assay, acridine orange and ethidium bromide staining, caspase-3 and -7 activity, DNA fragmentation and reverse transcription-quantita...

N-hexane neuropathy is an occupational disease caused by exposure to n-hexane, which is used as a solvent in silk screen printing. Here, we describe a 35-year-old man, a silk screen printer by profession, who presented with dizziness, distal swelling of both lower limbs for 10 months and tingling and burning sensation in both feet for 9.5 months along with cold allodynia. The patient had normal...
