Neodymium-YAG laser therapy for vascular lesions.
Landthaler M, Haina D, Brunner R, Waidelich W, Braun-Falco O.
Three patients with port-wine stains with a nodular surface, one patient with macrocheilia resulting from a port-wine stain, and one patient with a capillary hemangioma were treated with a Nd-YAG laser (mediLas, MBB-AT, Munich). Irradiance was between 800 and 1,600 watts/cm2, with energy fluence between 400 and 1,600 joules/cm2. Treatments were performed with local anesthesia on an outpatient basis. In all patients, marked improvements could be obtained after only a few treatments. Histologically there was necrosis of epidermis and dermis immediately after laser application, and ectatic vessels contained coagulated erythrocytes. Depth of coagulation was up to 3.5 mm. Quick restoration of epidermis was observed. After some days, macrophages, fibroblasts, and capillary blood vessels grew into the agglutination thrombi and ectatic vessels were replaced by granulation tissue and, later, by fibrous tissue. In comparison with the argon laser, the Nd-YAG laser coagulates at a much deeper level, but processes of tissue repair take longer and fibrosis is more pronounced after Nd-YAG laser application. Clinically, therefore, scar formation is more likely. Chilling the skin surface during irradiation and shorter exposure times may be effective in reducing the risk of scar formation in the future.

II. In vitro restoration by levamisole of mitogen responsiveness in zinc-deprived rats.
Gross RL, Osdin N, Fong L, Newberne PM.
The effect of levamisole on the in vitro responses of splenic and peripheral blood lymphocytes to phytohemagglutinin were investigated in zinc-deprived and pair-fed control rats. The in vitro response of lymphocytes from zinc-deprived rats was markedly impaired in comparison with that of controls. The addition of levamisole to cultures of zinc-deprived splenic lymphocytes significantly improved their response to phytohemagglutinin by 54%. The addition of levamisole to cultures of zinc-deprived peripheral blood lymphocytes significantly improved their response by 116.2%. The addition of levamisole to control lymphocyte culture had no effect. This study may be the first to evaluate the beneficial effect of an immunomodulating agent on immune function in a nutritionally deprived host.

An in vivo preparation (Thiry-Vella fistula) suitable for the measurement of intestinal absorption in the guinea pig.
Fabri PJ, Scott BC, Nelson EW.
A thiry-Vella isolated intestinal loop was constructed in the guinea pig. The procedure consisted of removal of a 30-cm segment of the jejunem, restoration of intestinal continuity by a jejunojejunostomy, and exteriorization of the segment through stomata sutured to the skin. The procedure was performed on seven guinea pigs of which three survived. The three survivors remained normal in maintenance of hair, feeding, and weight gain over a long period.
