Biogenic amines determination in some Romanian meat products.

Aim: Biogenic amines are compounds synthesized in human body which in high concentration become toxic and lead to a wide range of symptoms as palpitations, nausea and headache. Meat products can contain high levels of biogenic amines. Ingestion of such product can cause severe illness.

The protective effect of montelukast sodium on carbon tetrachloride induced hepatopathy in rat.

Aim: This study investigates the effects of montelukast sodium (MK) (CysLTLT1 receptor antagonist) on CCl(4)induced hepatopathy on rat.

Material And Methods: We worked on 4 groups of 10 Wistar male rats each. The groups received as follows: group I (control group) - saline, group II - MK 5mg/kg/day i.

[The influence of intermediate physical training on some non-enzyme antioxidants of oxidative stress, in moderate hypertension].

A group of patients with moderate hypertension (149-150/90-99 mm Hg) performed physical exercise for 3 months; we determined the oxidative stress in blood samples, by calculating the level of some biochemical markers, non-enzyme antioxidants, glutathione (GSH), total -SH groups (G-STH), nonprotein -SH groups (G-SHNP), their G-SHT/G-SHNP ratio, uric acid, malondialdehyde (MDA) and comparing the results with the values obtained from a group of healthy subjects. We found an increased oxidative stress at the HTA patients, with initial (Vi) decreasing values of GSH and uric acid, and with higher values of MDA. After the 3 months (Vf) of physical training, the oxidative stress improved, with increasing GSH, uric acid and decreasing MDA, compared to normal subjects.

[Evaluation of oxidative stress and enzymatic antioxidants in medium physical training of moderate arterial hypertension].

A group of patients with moderate hypertension (149-150/90-99 mmHg) performed physical exercise for 3 months; we determined the oxidative stress in blood samples, by calculating the level of some antioxidative markers, the enzymes SOD, CAT, GPx, MDA and comparing the results with the values obtained from a group of healthy subjects. We found an increased oxidative stress at the hypertensive patients, with initial higher values of SOD and MDA and with lower values of CAT and GPx, compared to the normal subjects. After the 3 months of physical training, the oxidative stress improved, with decreasing activity of SOD, GPx, MDA and increasing CAT, maintaining the ratio CAT/SOD and GPx/SOD superior compared to normal subjects.
