[Q]: Abstract: Electrocardiographic monitoring and provocative ventricular pacing were used to evaluate control and nadolol treatment groups 6 to 24 hours after left anterior descending coronary artery ligation in the dog. During the 6 to 24 hour period, the control group (n = 20) developed ventricular triplets at rates exceeding 270/min. Seven dogs spontaneously developed sustained monomorphic ventricular tachycardia (421 +/- 12 beats/min) at 13 +/- 2 hours. Sustained monomorphic ventricular tachycardia was present for 38 +/- 8 seconds before ventricular fibrillation developed. One dog developed recurrent monomorphic ventricular tachycardia, with six episodes lasting from 8 to 72 seconds (375 to 425 beats/min). At 24 hours, ventricular pacing produced sustained monomorphic ventricular tachycardia (378 +/- 12 beats/min) in 9 of 13 surviving animals. Nadolol administration 6 hours after coronary artery ligation (n = 19) lowered both the rate (241 +/- 8 versus 328 +/- 8 beats/min; p = 0.001) and the incidence (8 +/- 6 versus 198 +/- 61 per hour; p = 0.004) of rapid ventricular triplets and prevented sudden arrhythmic death (0%; p = 0.005). Nadolol failed to prevent sustained monomorphic ventricular tachycardia (88%; 365 +/- 12 beats/min) produced by ventricular pacing. The data suggest that nadolol prevents spontaneous sustained monomorphic ventricular tachycardia by selectively suppressing the arrhythmia trigger (rapid ventricular triplets) without altering the underlying arrhythmia substrate.

[Q]: Abstract: The NK-1.1(-) mouse was constructed by weekly injections of monoclonal anti-NK-1.1 antibody from birth through adulthood. Spleen cells from these mice have decreased NK-1.1+ cells and null (Thy-1- and B220-) cells. Their splenic NK activity to YAC targets was low and was not enhanced by IFN-alpha or IFN-beta. Bone marrow (BM) of these NK-1.1(-) mice have normal precursors to NK cells: 1) NK activity could be generated from NK-1.1(-) BM cells cultured in rIL 2 for 5 to 6 days. These cultured BM cells expressed Qa-5, Thy-1, AsGm-1, and NK-1.1 antigens. The precursor cells of these BM cytotoxic cells are NK-1.1-; 2) transfer of BM cells from the NK-1.1(-) mice reconstituted the NK activity of irradiated, NK-depleted recipients. Lymphokine-activated killer cells could also be generated from spleens of these NK-1.1(-) mice. Therefore, the NK-1.1(-) mice were specifically depleted of mature cytotoxic NK cells, but not the NK-1.1- precursors of NK cells. This mouse model is valuable to study ontogeny and physiologic relevance of NK cells.

[Q]: Abstract: The serum testosterone level (STL) was determined in 84 male and 32 female patients with gastric carcinoma and in 58 male and 20 female patients with benign diseases as a control group. The STL of the male patients with carcinoma was lower (446 +/- 149 ng/dl) than that of the male control group (532 +/- 132 ng/dl) (P less than 0.001). Even 17 male patients of the early carcinoma showed lower STL (440 +/- 117 ng/dl) than the normal group (P less than 0.001). In the female patients, it was also lower (31.6 +/- 16.0 ng/dl) than in the control group (46.3 +/- 15.3 ng/dl) (P less than 0.005). The postoperative STL of the cases surviving the gastrectomy was higher than the preoperative data in 32 male patients (P less than 0.005) as well as in 12 female patients (0.025 greater than P greater than 0.01), whereas it obviously decreased in the patients who died of recurrence. Therefore, it appears that gastric carcinoma decreases the STL by some mechanism.
