Depression of the generation of cell-mediated cytotoxicity after surgery

The Japanese Journal of Surgery
S MiyazakiH Tsuji


Effects of surgery on generation of cell-mediated cytotoxicity in mixed cell cultures were studied in patients with various carcinomas, and the results were compared to those in patients with benign lesion. Peripheral mononuclear cells were cultured with the B-lymphoblastoid cell Raji in a mixed culture and the induced cytotoxicity was measured by 51Cr release assay. In 15 patients with various carcinomas, the capacity of peripheral mononuclear cells to generate cytotoxic cells was significantly depressed 1, 3 and 6 days after surgery, as compared to findings before surgery. Preoperative levels were reverted to by the 8th postoperative day. In 8 patients with benign lesion, significant decreases in cytotoxic cell activity were observed 3 and 6 days after operation and, on the 8th postoperative day, there was a significant increase in the generated cytotoxicity, as compared to the preoperative activity. Thus, postoperative depression of the generation of cell-mediated cytotoxicity may affect the host-tumor relationship in patients with carcinoma.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.


Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Regulation of Vocal-Motor Plasticity

Dopaminergic projections to the basal ganglia and nucleus accumbens shape the learning and plasticity of motivated behaviors across species including the regulation of vocal-motor plasticity and performance in songbirds.

Myocardial Stunning

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.
