The effect of the beta-adrenergic agonist clenbuterol on immune function was examined in sheep. Twenty ewe lambs were housed indoors, with food and water available on an ad libitum basis, and immunized against somatostatin (SRIF) using a SRIF-ovalbumin conjugate. Ten of the lambs were also treated with clenbuterol (400 micrograms/kg) each day; 10 controls were not treated. After 5 wk of treatme...

We have recently shown that rat CYP2J4 is inducible by pyrazole in liver, small intestine, and olfactory mucosa. The aim of the present study was to determine whether mouse CYP2Js are also inducible by pyrazole, which was known to induce CYP2A5 in mouse liver and kidney, but not in lung or olfactory mucosa. CYP2J proteins were detected in mouse liver, lung, kidney, heart, eye, olfactory mucosa,...

The effect of trypsin on the morphology of the rat liver microsomal fraction isolated by differential centrifugation has been investigated. The microsomes were incubated at 37 degrees C and centrifuged thereafter under the conditions of their initial isolation. The trypsin-treated microsomes and the untreated controls were fixed in unbuffered osmium tetroxide and embedded first in gelose and th...

BACKGROUND CD4(+) T cell is acknowledged as a key factor in the initiation phase of liver ischemia reperfusion injury. The purpose of current study is to demonstrate the effect of antecedent near-term anti-CD25 monoclonal antibody treatment on IR-induced liver injury by modulation of CD4(+) T cells. METHODS 70% liver warm IR was induced in male C57BL/6 mice after anti-CD25 mAb or non-specific...

A 67-year-old man was referred to our emergency room for evaluation of exertional dyspnea and pretibial pitting edema of recent origin. At admission, neck vein engorgement was evident. Electrocardiography revealed a typical atrial flutter with 2:1 conduction; the serum cardiac enzyme levels were within normal limits. The laboratory findings were as follows: white blood cell 3,800/ mm3, hemoglob...

The cytological distribution of microtubule-associated protein 4 (MAP 4) (L. M. Parysek, C. F. Asnes, J. B. Olmsted, 1984, J. Cell Biol., 99:1309-1315) in mouse tissues has been examined. Adjacent 0.5-0.9-micron sections of polyethylene glycol-embedded tissues were incubated with affinity-purified MAP 4 or tubulin antibodies, and the immunofluorescent images were compared. Tubulin antibody labe...

Background: In this study, the protective effect of thymoquinone (TQ) and Nigella sativa seeds oil (NSO) was evaluated against oxidative damages induced by ethanol in rats. Methods: Animals were treated with ethanol 40% daily by gavages once a day for 4 weeks. NSO and TQ were injected intraperitoneal once a day for 4 weeks. The histopathological examination of liver, kidney, brain and heart was...
