Effect of rosella extract on development of fatty streaks lesions in female rats

This research was conducted to explore the effect of rosella (Hibiscus sabdariffa) on female rats on oxidative stress which induced by 0.5% H2O2. Oxidative stress has been investigated via tissue (aorta and heart) malonadyaldehyde (MDA) as indirect lipid peroxidation index. For atherosclerotic lesions follow up light microscopical technique has been applied. The result elucidate significant reduction in lipid profit parameters namely: low density lipoprotein (LDL-c), triglycerides, very low density lipoprotein (vLDL-c), atherogenic index and significant elevation in high density lipoprotein (HDL-c) in few animals treated with H2O2 and rosella extract, parallely, this research illustrate reduction in aorta and heart MDA concentration, concomitant with significant rising in glutathione (GSH) level. Histopathologically, this study revealed fatty streaks associated with infiltration of mononuclear inflammatory cells have been detected after 60 days, in animal treated with rosella revealed reduction in lipid vacuoles and proliferation in vascular smooth muscle cells (VSMcs) in media toward intimal layers after 40 days from treatment

Gingival squamous cell carcinoma in an ewe: a case report

Cauliflower, hemorrhagic, necrotic, and ulcerated mass located on the right of an ewe maxilla was diagnosed as gingival squamous cell carcinoma (GSCC). It was recognize microscopically by identifying malignant epithelial cell arranged as keratin pearls or various degrees of differentiation toward keratinocyte

Extraction of Staphylococcus aureus toxin from minced meat in Mosul City

This study was conducted to isolate and identify of Staph.aureus with its toxin from (41) sample of minced meat from different areas of Mosul city collected between April to July 2007. The positive samples to bacterial isolation reached 14.6%.In order to search the effect of bacterial toxin 0.2 ml and 0.4 ml of the toxins have been give orally and injected interperitonealy , respectively in albino mice. Histopathological changes of this toxin were described, the results showed the presence of vascular degeneration and apoptosis in hepatocyt as well as vascular and fatty degeneration in the tubercular epithelium of kidney. In the brain tissue the lesion was characterize by presence of vacuolation, gliosis and privascular odema, also the results revealed elongation and blunting of villi associated with lymphocytic proliferation in lamina properia of intestine. The histopathological changes were more severe in dose 0.4 ml as compared with 0.2 ml bacterial toxin

This study was conducted to examine the effect of lysate isolated from macrosarcocysts of Sarcocystis gigantea after inoculation into albino rats to follow up the pathological effect on heart, lung and skeletal muscle fibers. The results showed the presence of pathological changes, represented by hyperatrophy, congestion, associated with hyaline degeneration in myocardium of heart. In lung tissues severe congestion in each right and left lobes concomitant with emphysema, thickening was observed in wall of branchioles and blood vessels at 3-7 days have been seen. In skeletal muscles the result revealed the presence of multinecrotic areas which infiltrated with inflammatory cells accompanied by hyaline degeneration in muscle fibers at 3-7 days after treatment

This study was conducted to detect the fate of macrosarcocysts of Sarcocystis gigantea in the tongue and eosophagus of naturally infected sheep, via collection of 25 samples, 10 of which showed calcification. The results showed presence of white different size grains on the wall of the pale eosophagus, in addition to presence of nodules containing white chalky materials and on cutting by knife produced grunting sound which indicated calcification. Histopathological results showed presence of granulomatous nodules that contained necrotic centers infiltration by inflammatory cells. Some of which were free from zoites in addition to presence of calcium salt precipitation, which represented dystrophic calcification. Eosinophilic myositis appeared in the tongue was associated with ruptured cyst and released zoites in muscular tissue. Some histological sections revealed ruptured macrocystis with thin wall deposited between muscle bundles. In conclusion, this study showed that the fate of macrocysts included the formation of granulomatous nodules associated with dystrophic calcification and dead zoites i
