Ultrastructural basis for different pertechnetate uptake patterns by various human brain tumours.

Ultrastructural basis for different pertechnetate uptake patterns by various human brain tumours.

Patterns of pertechnetate uptake were correlated with ultrastructural properties of the endothelial wall in 14 human brain tumours. In tumours with reduced uptake of the radionuclide, intercellular tight junctions were observed whereas absence of intercellular tight junctions was characteristic of all tumours with an increased uptake of pertechnetate. In some tumours with increased uptake, fene...

Unilateral breast uptake of 99mTc-pertechnetate.

[Uptake of bleomycin by human brain tumors].

Bleomycin (BLM), discovered by Umezawa et al. (1966a, b) is a kind of cytostatic antibiotic complex produced by a strain of Streptomyces verticillus, and was found by Ichikawa et al. (1967, 1968) to be highly effective against human squamous cell carcinoma. These authors observed relatively high concentration of BLM in the skin after subcutaneous injection in mice, and suggested that the therap...

Legal Basis for Donating Organs for Brain Death Patients

Brain death involves the complete and irreversible destruction of brain activity characterized by profound coma, apnea and the absence of all brainstem reflexes. The issue of organ transplantation is a very important issue in the field of jurisprudence and law in addition to being one of the issues to be considered and analyzed in the medical world, especially in jurisprudence and the issue has...

LDH isoenzymes in cerebrospinal fluid in various brain tumours.

This study examined the isoenzymatic pattern of LDH in the cerebrospinal fluid (CSF) as well as the ratio between the five fractions of LDH among patients with various brain tumours, carcinomatous meningitis and control groups. LDH 1/LDH 2 less than 1 was found significant for carcinomatous meningitis (p less than 0.001) and brain metastases (p less than 0.001). LDH 1/LDH 2 ratio was found to b...
