## Abstract Epidemiological and intervention studies correlate anthocyaninβrich beverages and a low incidence of coronary heart diseases. Since endothelinβ1 (ETβ1) and nitric oxide (NO) produced by endothelial NO synthase (eNOS) are vascular tension regulators secreted by endothelial cells, we stud

β¦ Synopsis
Nitric oxide is generated from L-arginine by nitric oxide synthase (NOS), which has at least three isoforms; endothelial-type NOS (eNOS) and brain-type NOS (bNOS) are constitutive enzymes, and inducible-type NOS (iNOS) is expressed after stimulation. Studies by the avidin-biotin immunocomplex method, revealed eNOS immunoreactivity exclusively in the human eccrine clear cells. No eNOS immunoreactivity was observed in the eccrine dark cells or myoepithelial cells. No staining of iNOS or bNOS was observed in the eccrine gland. These findings indicate that NO plays a physiological part in the production and/or excretion of sweat in the human skin eccrine gland.

## Abstract Cultured cells derived from the cerebromicrovasculature can be shown to contain the enzyme nitric oxide synthase (NOS) by NADPH diaphorase staining. Nos is located largely as a distinct crescent adjacent to the nuclear membrane. NOS in these cells appears to be associated with the micro
Nitric oxide (NOβ’), generated by nitric oxide synthase (NOS II) from immunostimulated cells during infection, plays an important role in host immune defense against microbial invasion. The impact of different rates of NOβ’ production on host cell function has not been defined. Herein, we describe the
Although a multisystem disease, systemic sclerosis (SSc) most commonly affects the skin. The skin lesion is characterized by progressive changes, chief amongst which are vascular abnormalities, including endothelial cell (EC) injury and death, and dermal fibrosis. The pathogenesis of the vascular ch
