Abstract

Papillophlebitis is an uncommon disease in clinical practice. We would like to present a case of a 29-year-old patient with atypical orbital pain and fl ashings, presenting relative aff erent pupillary defect and already typical of the disease entity: ophthalmoscopic picture of the fundus and big blind spot in perimetry. We present a complex and interdisciplinary diagnostic process that excludes general diseases such as hypertension, diabetes, coagulation disorders and neurological causes. We leave the only identifiable abnormality and potential source in the infl ammatory process of periodontal infl ammation and sinus jaw changes. We also describe the process of remitting the changes and fi nally a favorable end result of the primarily a very disturbing clinical picture that this disease may present.

Abstract

The study examined changes in lysine decarboxylase (LDC), ornithine decarboxylase (ODC) and tyrosine decarboxylase (TyDC) activity in tissues of pea (Pisum sativum L.) infested by the pea aphid (Acyrthosiphon pisum Harris). The aphid induced increased ODC activity after one day and at two weeks. The effect was clearly systemic. TyDC activity increased after one day and at one week at feeding sites (aerial parts), while LDC activity increased only after one day of infestation and then decreased. Attack by aphids also affected enzyme activity in root tissues not directly damaged by the herbivores. The mechanisms of the response induced by pea aphid infestation in pea are discussed.
