The presence of carcinoplacental alkaline phosphatase (CP Alk P) was demonstrated in the cells of malignant and premalignant states of the human stomach, colon and rectum using the immunoperoxidase technique. It was shown to be present in 7 out of 18 carcinomas of stomach and 7 of 17 cases of
We investigated the serum activity of the fifth fraction of L-lactate: NAD-oxidoreductase (E.C.1.1.1.27) and serum alkaline phosphatase activity prior to diagnostic curettage in patients with abnormal and atypical endomertial hyperplasia. We also determined them in 75 patients with carcinoma of the
In 24 men with precancerous states of the larynx, i.e. leukoplakia, papillomas and pachydermia, the peripheral blood lymphocytes were cytochemically stained for N-acetyl-beta-glucosaminidase, beta-glucuronidase, acid phosphatase and glycogen (PAS reaction). The results were expressed in terms of the
Activity of beta-glucuronidase (GR) and acid phosphatase (AP) has been determined in peripheral blood neutrophils from 24 men with precancerous states of the larynx that is leukoplakia papillomas and pachydermia by means cytochemical methods described by Hayashi et al., and Barka and Anderson,
In 24 men aged 32 to 58 years with precancerous states of the larynx, i.e., leukoplakia, papillomas and pachydermia the peripheral blood lymphocytes were cytochemically stained for N-acetyl-beta-glucosaminidase, beta-glucuronidase, acid phosphatase and glycogen; and the neutrophils were stained for

Head neck cancer (HNCA) in North-East India accounts for 54.48% cancers at all sites, one of the highest in the country. Increased serum lactate dehydrogenase (LDH) activity is considered as a marker of cellular necrosis while serum alkaline phosphatase (ALP) is recognized as an important
Prostate-specific antigen (PA), gamma-seminoprotein (gamma-Sm) and prostatic acid phosphatase (PAP) have been evaluated in patients with prostate cancer, benign prostatic hyperplasia (BPH), chronic prostatitis and acute prostatitis. PA has proved to be diagnostically more sensitive than PAP and
Prostate-specific antigen (PSA) and prostatic acid phosphatase (PAP) have been evaluated in patients with prostate cancer, benign prostatic hypertrophy (BPH), and prostatitis. PSA has proved to be diagnostically more sensitive than PAP for the detection of prostate cancer: 95.0 per cent vs 60.0 per
Cytochemical investigations performed in 24 men with precancerous states of the larynx, i.e. leukoplakia, papillomas and pachydermia, indicated that the peripheral blood neutrophils from these patients exhibit a significant intracellular deficiency of beta-glucuronidase activity and of total lipids,
In patients with precancerous states and cancer of the uterine cervix prior to and after radiotherapy exhibit the decreased activity of neutrophil beta-glucuronidase. Moreover, patients treated by radiotherapy before the age 6 to 9 years demonstrate deficiency of N-acetyl-beta-glucuronidase in the
In patients with precancerous states and cancer of the larynx prior to and after radiotherapy exhibit the decreased activity of neutrophil beta-glucuronidase. Moreover patients treated by radiotherapy before the age of 6 to 9 years demonstrate deficiency of N-acetyl-beta-glucosaminidase in the above
In 35 patients with leukoplakia or erythroplastic lesions of oral mucosa, the immunohistochemical study of Langerhans cells and various types of lymphocytes demonstrated increasing changes in cellular immunoreactivity in benign leukokeratosis, dysplasia and in situ or microinvasive carcinoma.
Intestinal metaplasia is often associated with human gastric carcinoma. Intestinalization seems to be a typical example of abnormal differentiation and is possibly a precancerous state. For investigation of intestinal metaplasia, a method for visualizing disaccharidases using Tes-Tape was developed;
