A method for determining chloroform, 1,1,1-trichloroethane, carbon tetrachloride, and trichloroethene in breath samples was developed. It consisted of collecting samples in 40-ml. glass-silanized tubes that were 16-in. long and had a 0.64-in. diameter. The ends tapered, resulting in a tube with a 1/4-in. diameter that was 1 3/4-in. long; each end had a shutoff valve attached. One end had a stri...

OBJECTIVE To estimate the hepatoprotective effects of the methanolic seed extract of Eugenia jambolana Lam. (Myrtaceae), in Wistar albino rats treated with carbon tetrachloride (CCl(4)). MATERIALS AND METHODS Liver damage in rats treated with CCl(4) (1ml/kg/Bw, administered subcutaneously, on alternate days for one week) was studied by assessing parameters such as serum glutamate oxaloacetate...

The mechanism by which the ingestion of carbon tetrachloride results in distinct and reproducible histological alterations of the liver has been investigated intensively, both in &JO and in vitro (3-11). The mitochondria of liver cells are particularly vulnerable to this lipid solvent, as shown by their increased permeability (3), decreased coenzyme content (7, 8), and the loss of their ability...

Maresin 1 (MaR 1) was recently reported to have protective properties in several different animal models of acute inflammation by inhibiting inflammatory response. However, its function in acute liver injury is still unknown. To address this question, we induced liver injury in BALB/c mice with intraperitoneal injection of carbon tetrachloride with or without treatment of MaR 1. Our data showed...

Animal models prepared by treatment with toxic compounds such as a carbon tetrachloride have been used to examine drug disposition in hepatic diseases. However, it is possible that these compounds accumulate and cause damage to other organs as they are administered systemically. In this study, we used the liver surface application technique to deliver a toxic compound to the liver to prepare an...

1. An investigation has been made of the changes occurring in lysosomal enzyme activities during the early development of experimentally produced liver injury in the rat. Three enzymes have been studied: acid phosphatase, acid ribonuclease and beta-glucuronidase. Four different methods of inducing liver injury have been used: administration of carbon tetrachloride, thioacetamide, dimethylnitros...

In this study, a high-performance TixZrySizO flash memory is demonstrated using a sol-gel spin-coating method and formed under a low annealing temperature. The high-efficiency charge storage layer is formed by depositing a well-mixed solution of titanium tetrachloride, silicon tetrachloride, and zirconium tetrachloride, followed by 60 s of annealing at 600°C. The flash memory exhibits a notewor...

Amarogentin, a secoiridoid glycoside that is mainly extracted from Swertia and Gentiana roots, has been suggested to exhibit many biological effects, including anti-oxidative, anti-tumour, and anti-diabetic activities. The present study was designed to evaluate the protective effects of amarogentin on carbon tetrachloride-induced liver fibrosis in vivo and the underlying mechanism. Fibrosis was...

Effects of single intraperitoneal administration of trichloroethylene, 1,1,1-trichloroethane, and carbon tetrachloride (positive control) on the plasma contents of lipoproteins were investigated in rats. Plasma was fractionated to VLDL, LDL, and HDL by sequential ultracentrifugation. On the administration of carbon tetrachloride at 30 to 1000 mg/kg, VLDL and HDL were reduced dose-dependently, b...

In this study the effects of an aqueous suspension of a commercial preparation of the mushroom Coprinus comatus on oxidative stress induced in rats by alloxane and carbon tetrachloride was examined. The effects were estimated from changes in the biochemical parameters (xanthine oxidase, glutathione peroxidase and catalase activity, reduced glutathione content, and extent of lipid peroxidation) ...
