The skin specimens of the patients with psoriasis were examined with electron microscope after the photo-herbal therapy of Anglica dahurica, Sichuan variety and ultraviolet A (UVA) irradiation. It was found that the therapeutic effects of this photo-herbal therapy were similar to those of the photochemotherapy of psoralen and UVA. Both of the therapies could accelerate the degeneration amibreakdown of the psoriatic cells and normalize the proliferation of the basal cells. However the large vacuoles formed in the nuclei of the psoriatic cells after the photochemotherapy reported by other authors could not be revealed after the combined treatment of A. dahurica and UVA.

Experimental respiratory distress syndrome was induced with oleic acid injection to 8 dogs. 4 dogs received no treatment and served as controls, and the other 4 were treated with anisodamine (654-2) after oleic acid injection.All the animals were killed at the 72nd hour after injection, and their lung tissues were studied under electron microscope.It was found that anisodamine was able to reduce the severity of pulmonary edema. There was accumulation of neutrophils in the pulmonary capillaries and hyaline membrane formation on the epithelial surface of the alveoli and alveolar duct walls. Neutrophil accumulation in the capillaries may indicate that the content of the blood was kept at a fairly high level at the 72nd hour after injection in spite of anisodamine treatment. The chief constituent of the hyaline membrane was fibrin. At the sites of hyaline membrane formation, focal cyto-plasmic necrosis of the type I epithelial cells was often observed.
