[Calcitonin levels in the serum of psoriatic patients].

In this study the serum calcitonin concentrations were assessed in patients with Psoriasis vulgaris. The results were compared with healthy volunteers. The serum calcitonin levels of psoriatic patients was significantly increased than in healthy volunteers.

[Experimental studies of the pathomechanism of portal encephalopathy. II. Monoamine oxidase (MAO) activity in the rat brain after porta- caval shunt using 2 different methods].

The authors present effect of the end to side portacaval shunt (E-S PCS) and side to side portacaval shunt (S-S PCS) on monoamine oxidase (MAO) activity in brain cortex and cerebellum of rats. There were significant differences between two experimental models of PCS. Our results show greater increase in MAO activity after end to side portacaval shunt.

[Experimental studies of the pathomechanism of portal encephalopathy. I. Changes in monoamine oxidase (MAO) activity in the cerebral cortex and cerebellum of rats after portacaval shunt].

Rats with portacaval shunt (PCS) were used as a model of hepatic encephalopathy and compared to sham operated controls. Neurochemical studies in rats have demonstrated increased activity of MAO in brain cortex and cerebellum at 20, 40, and 60 days after surgery. The greatest increase of MAO activity was seen 60 days after PCS.
