Triple helical lentinan, a beta-(1-->3)-D-glucan from Lentinus edodes, was denatured in dimethylsulfoxide (DMSO) into single random coils. The randomly coiled lentinan/DMSO solutions were diluted with pure water to w(H) (the weight fraction of water in the mixed solvent) of 95%, and their intrinsic
Lentinan (Ajinomoto, Japan) was administrated intraperitoneally (i.p.) and intranasally (i.n.) at different doses (1, 5 and 10 mg/kg) to rats. Effectiveness of Lentinan treatment was evaluated by comparative testing of cell activation (establishing the number, glycolytic and acid phosphatase
OBJECTIVE
To study the therapeutic effect and mechanism of thermotherapy combined with thoracic injection of lentinan in treatment of cancerous hydrothorax (CH) in patients with lung cancer.
METHODS
Sixty lung cancer patients complicated with CH were randomly assigned to the observation group and
CBA/H mice were given the immunomodulator lentinan in multiple, ascending doses before (prophylactic) or after (therapeutic) inoculation with tetrathyridia of Mesocestoides corti or as a single prophylactic dose. The latter was without effect, but increasing multiple prophylactic and therapeutic
A 78-year-old woman underwent gastrectomy for type 3 gastric cancer with pyloric stenosis, which was detected in November 1997. Thoracic and abdominal CT and other diagnostic procedures were conducted regularly for 5 years after surgery. The patient was recurrence-free and her clinical course was
The combination treatment of non-specific immunomodulator Lentinan (LNT) and OK-432 is effective for controlling Th1/Th2 balance and inducing Th1 dominant status in cancer patients. According to this rationale, we tried an administration of LNT and OK-432 in the pleural or peritoneal cavity for
The early cellular responses to antitumor immunomodulators and conventional inducers, especially the polymorphonuclear leukocyte (PMN) responses, were examined in the peritoneal cavity of mice to investigate their effect on primary defense mechanisms. Immunomodulators were classified into 5 groups
It is very important to control the Th2-dominant condition in cancer patients while they are undergoing immunotherapy. OK-432 powerfully guides Th1 cytokine, but sometimes it can not eliminate the Th2 dominant state in cancer patients, which is needed to induce Th2 cytokine. Premedication with
LTN and OK-432 combined therapy is effective for controlling Th1/Th2 balance. We tried a repetitive administration of LTN and OK-432 in the pleural or peritoneal cavity for patients with malignant effusion. Of all 11 lesions of the 10 cases, 7 revealed complete remission and 1 revealed partial
Polysaccharides are ideal green synthetic raw materials to improve the biocompatibility of metal nanoparticles. However, polysaccharides generally have weak reducibilities, being challenging supports for the direct preparation of Ag nanoparticles. In this work, gold nanoclusters were prepared using
A 64-year-old man complaining of anterior chest pain, weight loss, and neck tumors was found to have advanced gastric cancer with pleuritis carcinomatosa and multiple lymph node and bone metastases. The patient was treated with combination chemotherapy consisting of mitomycin C (MMC), tegafur (UFT),
We report on a green procedure for the synthesis and stabilization of gold nanoparticles (AuNPs) from chlorauric acid (HAuCl4) with the use of a β-glucan known as Lentinan (LNT) without external reducing or stabilizing agents in aqueous medium. LNT adopted triple helical conformation in water, which
