Regulatory Effect of Lymphokine-Activated Killer Cells on Epidermal Proliferation Induced by Cholera Toxin in Mice
We investigated the effects of lymphokine-activated killer (LAK) cells on epidermal hyperplasia induced by cholera toxin (CT). LAK cells showed cytotoxic activity against both tumor cell lines and proliferating normal cells including skin epidermal cells. When 1 x 10(7) LAK cells were injected intradermally together with 1.0 ng of CT, epidermal hyperplasia was markedly suppressed. The LAK effectors inhibiting epidermal hyperplasia showed surface phenotypes of asialo-GM1+, Thy-1+, Lyt-2- and L3T4-, that were different from those of LAK cells killing tumor cells in vitro. Epidermal hyperplasia induced by CT was not suppressed by topical administration of cytokines such as interleukin-2, interferon and tumor necrosis factor. Therefore, the antiproliferative effect of LAK cells might be attributed to their direct action on the epidermal cells.</p
Combined therapy with interleukin 2 and indomethacin in mice inoculated with MH134 hepatoma.
The antitumor effects of indomethacin and interleukin 2 (IL-2) were studied in C3H/HeJ mice inoculated with MH134 hepatoma cells. Combined treatment with indomethacin and IL-2 augmented natural killer (NK) cells in mice with MH134-induced peritoneal carcinomatosis, and the survival of the treated mice was significantly longer than the non-treated mice. In animals with subcutaneous MH134 tumors, the combined therapy with indomethacin and IL-2 significantly suppressed tumor growth and induced complete regression of the tumor in three out of five mice. These results suggest that indomethacin and IL-2 therapy could be effective on human gastrointestinal cancer cells as well.</p
A case of chronic pancreatitis successfully treated by endoscopic removal of protein plugs.
A 56 years old male with chronic pancreatitis complained of intractable abdominal pain, anorexia, emaciation and peripheral edema. Medical treatment initiated only partial improvement in the general condition and hypoproteinemia. Endoscopic retrograde cholangiopancreatography revealed multiple filling defects in the dilated main pancreatic duct. Endoscopic aspiration of pure pancreatic juice yielded numerous protein plugs. The endoscopic removal of protein plugs from the pancreatic duct resulted in remarkable improvement in symptoms, laboratory findings and ERCP findings. We consider this procedure to be an important new treatment of chronic pancreatitis.</p
