Significant increase of liver succinic dehydrogenase (SHD) activity was produced by carrageenin-induced edema in rats. Pretreatment with human placental extract "Placentrex" inhibited the increased liver SHD activity in a dose-dependent manner. "Placentrex" was found to have no effect on the liver
Previous studies suggest that treatment with statins reduce beta amyloid (Abeta) deposition in brains of mouse models of Alzheimer's disease (AD) and may reduce the prevalence of AD in humans. Since lipophilicity influences the biological efficacy of statins, we compared the effects of lovastatin, a
Ragged red fibers are an important marker for mitochondrial disease. To evaluate the hypothesis that mitochondrial dysfunction may play a role in the pathogenesis of aging and inclusion body myositis, we studied the frequency of ragged red fibers in muscle biopsy specimens from 15 young and 13 old
The mesonephroi of two groups of Rana esculenta collected from two rice fields near Pavia, one relatively unpolluted and one polluted, were morphologically and histochemically investigated. Light and electron microscopy analyses were performed and certain enzyme activities studied (succinic
Ultrasound-guided ethanol injection (PEI) is an effective treatment of autonomously functioning thyroid nodules (AFTN) but little is known about the tissue lesions induced by alcohol. We report morphological changes of an AFTN which was removed after successful PEI treatment. At histological
Workers are occupationally exposed to Pd and Pd-complexes during the refining process, in particular in Pt-refineries. The metal is increasingly used as component in fine jewellery, is commonly present in dental alloys, and is also employed in telecommunication systems.In view of the toxicity of Pd
OBJECTIVE
This study was conducted to 1) measure the sensitivity of human and mouse macrophages to metal ions which are released from dental biomaterials, 2) compare these sensitivities with those of other cell types in the oral cavity, and 3) determine if metal ions alter the metabolism and
Prepubertal rats treated orally with di-n-pentyl phthalate at 2.2 g/kg body weight were killed at 1, 3, 6 and 24 hr following a single dose, and after 2, 3 and 4 days of repeated daily dosing. At 3 hr Sertoli cells in a proportion of the seminiferous tubules showed vacuolation of the perinuclear
Nickel-containing alloys commonly are used in medical and dental applications that place them into long-term contact with soft tissues. The release of Ni ions from these alloys is disturbing because of the toxic, immunologic, and carcinogenic effects that have been documented for some Ni compounds.
The objective of this study was to investigate whether alcohol administration exerts a synergistic effect on jejunoileal bypass-induced liver dysfunction in rats. Male Wistar rats were subjected to 90% jejunoileal bypass or sham operation. For 10 weeks, subgroups were pair-fed either an
OBJECTIVE
To compare the effects of crude and wine-processed Rhei Radix et Rhizoma on upper-energizer disease and hepatic energy metabolism in mice.
METHODS
The streptococcal pneumonia rats model and acetic acid burning mouth ulcers rats model were established and randomly divided into three groups:
The acute pancreatitis (AP) was induced with sodium deoxy-cholate in SD rats. Succinic dehydrogenase (SDH), acid phosphatase (ACP) and cytochrome P450 were taken as marked enzyme in estimation of mitochondria, lysosome and microsome to observe the functional and structural changes of the pancreatic
