A comparison was made of the amount and crystallinity of mineral deposited in the course of the arteriosclerosis in arterial walls in diabetic patients and in individuals with normal carbohydrate metabolism. The macroscopically unchanged tunica intima, fibro-lipidic plaques and bone-like lamellae were taken from aorta thoracalis , aorta abdominalis, arteriae femorales and arteriae coronariae in the course of the autopsy of 17 insulin dependent diabetic individuals and of 9 persons with arteriosclerosis, but with normal carbohydrate metabolism, called control group. The total inorganic constituents in the three kinds of samples were determined by ashing of dried samples at 600 degrees C for 6 h. Crystallinity of mineral was defined as the ratio of the spins connected with the radiation-induced stable paramagnetic centers present in the crystalline lattice of hydroxyapatite crystal, to the total ash content of the sample. An increase in the amount and in the crystallinity of deposited mineral was observed when consecutive stadia of development of arteriosclerotic lesions were compared. This phenomenon resembles the maturation of mineral observed in the course of bone development.

Maras Powder (MP) is a special kind of smokeless tobacco widely used in the southeast region of Turkey especially in Kahramanmaras and Gaziantep and other southeastern cities. It is obtained from a tobacco species, Nicotiana rustica L and ash of oak or grapevine wood. Tobacco may increase oxidative stress, which is related to the products of the oxygen metabolism taking place in all cells. Cellular antioxidants, e.g. catalase (CAT), superoxide dismutase (SOD) and glucose 6-phosphate dehydrogenase (G6PD) protect the cell against oxidative damage. An imbalance between the ROS and antioxidants in favour of ROS is described as oxidative stress. In this study, we aimed to investigate the effect of MP on antioxidant enzyme levels and lipid peroxidation. We measured malondialdehyde (MDA), CAT, SOD and G6PD levels in blood of 68 MP users and 30 healthy controls who did not use MP. CAT, SOD and G6PD levels were lower in MP users than in the controls. On the other hand, lipid peroxidation levels (MDA), one of the best indicators of cytological damage, was increased in MP users compared with the controls. The present study showed that MP increases oxidative stress, which may cause many systemic disorders, including arteriosclerosis.

The pharmacological effects were investigated of fermented red pepper (HF-S), which consisted of 14.7% carbohydrate, 1.5% lipid, 4.9% protein, 0.3% ash, 78.2% moisture content, with 0.15% capsaicin and 0.06% dihydrocapsaicin. Oral administration of 0.25 mL HF-S for 3 weeks produced significant changes of the perirenal fat pad weight compared with the HF-control group, suggesting a suppressive effect on lipid accumulation and a significant decrease in the risk of arteriosclerosis. The HF-S (0.25 mL) group also showed a lower plasma TG, TC level and atherogenic index than that of the HF-control. In addition, the HF-S (0.25 mL) group showed a marked increase in the production of glutathione, which is the major endogenous antioxidant, and a decrease in the production of lipid peroxide as the product of chemical damage by oxygen free radicals. It is assumed that the effect of HF-S might relate to high glutathione production on the suppression of lipid peroxidation. HF-S stimulated not only the proliferation of macrophages (as high as the positive control, LPS at 1000 microg/mL) but also mitogenic activity (1.2-fold of LPS at 100 microg/mL).
