The changes in the activities of certain lysosomal hydrolases, viz., beta-glucuronidase, beta-N-acetylglucosaminidase, beta-galactosidase, beta-glucosidase, alpha-glucosidase, alpha-galactosidase, alpha-mannosidase, cathepsin B, cathepsin D, and collagenolytic cathepsin, in serum and heart of rats subject to myocardial infarction with isoproterenol, were studied during the periods of peak infarction and recovery. The activities of all the enzymes assayed exhibited a significant increase both in serum and in heart at peak infarction stage and these levels returned to normal during the stage of recovery and repair. The infiltration of inflammatory cells at the infarct regions and the altered lysosomal fragility are probably responsible for the increased activity of the enzymes studied. This may also bring about the catabolism of connective tissue constituents as reported in literature.

Alterations in the activities of certain lysosomal enzymes such as beta-D-galactosidase, beta-D-glucosidase, beta-D-glucuronidase, alpha-L-fucosidase, N-acetyl-beta-D-glucosaminidase, cathepsins B and D were studied in serum and tissue homogenates of buccal mucosa of hamsters treated with 0.5%, 7,12-dimethylbenz[a]anthracene (DMBA) in liquid paraffin. Among the enzymes studied, the activities of beta-D-galactosidase and N-acetyl-beta-D-glucosaminidase showed significant elevation both in serum and tissue homogenates fro papilloma onwards and the elevations were progressive with the development of carcinomas. The elevations in the activities of alpha-D-fucosidase and cathepsin D were found to be significant from papillomatous tissue onwards whereas in serum they showed higher activities only in carcinoma stages. The activities of beta-D-glucosidase, beta-D-glucuronidase and cathepsin B in both serum and in tissue homogenate were elevated markedly only in carcinoma stages. It is suggested that beta-D-galactosidase and N-acetyl-beta-D-glucosaminidase may be used as diagnostic markers for premalignant and malignant lesions of oral mucosa.
