Inhibition of virus multiplication by immunoactive peptides

In the present study we show that peritoneal macrophages obtained from the mice treated with the immunoactive peptides inhibit the multiplication of Herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2), but not that of vesicular stomatitis virus (VSV), and that the intraperitoneal administration of the peptides suppresses the infection with HSV-1 in mice.     

Immunoreactive glucagon in the vascular walls of the rat

We detected immunohistochemically immunoreactive glucagon (IRG) in the smooth muscle of blood vessels and the myoepithelial cell of sweat glands of rats using two antisera against pancreatic glucagon; OAL-123 and 30K. The content of IRG in the blood vessels was found to be 320-1, 270 pg per g wet tissue weight. Filtration of the extracted IRG through a Bio Gel P-30 column yielded a single peak of IRG at 3,500 daltons, the same elution volume of pancreatic glucagon. These findings suggest that the blood vessels of the rats is one of the extrapancreatic sources of IRG in plasma, although physiological role of the IRG is not known.
