Spontaneous coronary artery dissection during cisplatin and capecitabine therapy.

Introduction: Spontaneous coronary artery dissection is a rare cardiovascular disease that can cause acute myocardial infarction and sudden cardiac death. The mechanism of this pathology and the optimal treatment are not fully understood.

Presentation Of Case: An acute myocardial infarction developed while a fifty five years old woman with a rectal adenocarcinoma was receiving a cisplatin and capecitabine therapy.

DETERMINATION OF ANTIOXIDANT ACTIVITY OF WINES AND WINE'S MAJOR PHENOLIC COMPOUNDS BY ELECTRON SPIN RESONANS, USING SPIN-TRAPS METHOD.

Our results showed, that EPR method using DMPO spin-trapping is characterized with high sensitivity, which enables to define anti oxidative activity of very small concentration of major antioxidants in Georgian and foreign red and white wines and in red wine. It was concluded, that red as well as white wines have very high anti oxidative activities. Herewith it has to be mentioned, that anti oxidative activity of red wine does not always correlate with the total concentration of phenol in it and mostly depends on the concentration of different major antioxidants.

[Effect of ascorbic acid (vitamin C) on the EPR spectra from the black and red hair].

The EPR spectra of melanin's free radicals in natural black and red hair have been investigated. It is show that the EPR spectrum of black hair is slightly asymmetric singlet with g=2,0035 and ΔH=0,5 mTl. The EPR spectrum of red hair with g=2,0053 differs from the spectrum of black hair.

[Computer simulation of ESR signals of liver paramagnetic centers].

Changes of paramagnetic centres concentration characterized by g-factors values of 1.94, 2.2, and 2.

[Computer modeling of ESR spectra of the plasma in patients with Down's syndrome].

ESR technique at 77 degrees K was used for studying the blood plasma ESR signals of patients with Down syndrome and of healthy people. It was observed that the first exhibited a tendency towards a decrease of ESR signal with g = 4.3 and increase of the ratio of ceruplasmin (g = 2.
