The study was designed to evaluate the hepatoprotective activity of P. guajava in acute experimental liver injury induced by carbon tetrachloride, paracetamol or thioacetamide and chronic liver damage induced by carbon tetrachloride. The effects observed were compared with a known hepatoprotective agent, silymarin. In the acute liver damage induced by different hepatotoxins, P. guajava leaf ext...

The crude methanolic extract of Dillenia indica Linn. (Dilleniaceae) leaves has been investigated for the evaluation of antimicrobial and cytotoxic activities. Organic solvent (n-hexane, carbon tetrachloride and chloroform) fractions of methanolic extract and methanolic fraction (aqueous) were screened for their antimicrobial activity by disc diffusion method. Besides, the fractions were screen...

Six groups of rats on different diets were exposed to the inhalation of carbon tetrachloride (about 300 p. p. m.) for 150 days. Food intake and changes in weight were followed throughout the experiment. Animals fed a diet low in protein showed greater susceptibility than rats on a diet high in protein. Methionine was a good substitute for protein (casein) in the diet. Increase in fat intake wit...

A number of studies including those of Cornish and Block (1960) have measured the marked increase in serum enzyme levels following acute exposure to CC4 vapor. If it is assumed that these enzymes are being released from damaged tissue, one would anticipate that smaller molecular weight compounds, such as amino acids, would also be released. Increased urinary excretion of free amino acids or alt...
