Type I and Type II Hereditary Angioedema: Clinical and Laboratory Findings in Iranian Patients.

Background: Hereditary angioedema (HAE) is a rare autosomal dominant disorder characterized by C1-INH (C1 esterase inhibitor), low serum levels (type I), dysfunction (type II) or normal serum levels and function (type III), which lead to subcutaneous and submucosal edema attacks. The aim of this study was to investigate the demographic, clinical and laboratory findings of Iranian patients with HAE.

Methods: The patients with a history or symptoms of angioedema who were referred to Immunology, Asthma and Allergy Research Institute (IAARI) between Jan 2006 and Jan 2014, were assessed based on a specific questionnaire and laboratory evaluation.

Carnosine exerts neuroprotective effect against 6-hydroxydopamine toxicity in hemiparkinsonian rat.

Parkinson's disease (PD) is the second most common disorder of the central nervous system due to the degeneration of mesencephalic dopaminergic neurons. Current treatments for PD have a symptomatic relief strategy with no prevention of disease progression. Due to the neuroprotective and antiapoptotic potential of the natural dipeptide carnosine, this study was conducted to assess its beneficial effect in 6-hydroxydopamine (6-OHDA)-induced model of PD in rat.
