The treatment of massive upper gastrointestinal hemorrhage by gastric hypothermia was studied clinically in 23 patients: five with peptic ulcer, six with multiple gastric erosions, nine with portal hypertension and varices, and three with coagulation defects. Hemorrhage was controlled in 13 of the patients. The high mortality (14 out of 23 patients) was attributed to the severity of the bleeding and to the underlying disease, particularly in patients with liver failure. This form of treatment is a useful method of treating selected patients with upper gastrointestinal hemorrhage.

Cimetidine, a drug in widespread use in the treatment of peptic ulcer disease, is eliminated primarily via urinary excretion. We examined cimetidine transport by rabbit proximal straight tubules perfused in vitro. [3H]Cimetidine in the bath was actively secreted into the tubule lumen. There was a curvilinear relationship between the rate of cimetidine secretion and the concentration of bath cimetidine. Cimetidine secretion was inhibited by hypothermia and ouabain. Quinine, tolazoline, probenecid, phloridzin, creatinine, p-aminohippurate, and cimetidine sulfoxide inhibited cimetidine secretion in a dose-related manner. At low cimetidine concentrations lumen-to-bath transport rates were only 11-18% of bath-to-lumen secretory rates. High performance liquid chromatographic analysis of collected tubular fluid showed a predominance of cimetidine and a small amount of cimetidine sulfoxide in ratios similar to those of the bath. These studies show that cimetidine is actively secreted into the lumen of rabbit proximal straight tubules in vitro. Secretion probably occurs via the organic base and to a lesser extent the acid transport systems.

The systemic inflammatory response to cardiopulmonary bypass (CPB) is associated with increased production of cytokines. This systemic inflammatory response characterized by the activation of interleukin-6 (IL-6) and interleukin-8 (IL-8) during and after CPB is well documented. A prospective, randomized, double-blind study was performed so as to understand the effects of low-dose methyl prednisolone sodium succinate (MPSS) on the circulating levels of serum cytokines and clinical outcome. Twenty patients were randomly divided into two groups on the basis of the administration of low-dose (1 mg/kg) MPSS (n = 10) and placebo (n = 10) into the pump prime solution. All patients were scheduled to undergo a primary elective coronary artery bypass grafting operation. Patients receiving concurrent corticosteroids, salicylates, dipyridamol or anticoagulants were excluded from the study. Other exclusion criteria were concurrent chronic obstructive pulmonary disease, chronic renal failure, insulin-dependent diabetes, congestive cardiac failure, peptic ulcer history, prior cardiac operations, recent (in a one-month period) myocardial infarction and steroid dependency. Mild systemic hypothermia (30-32 degrees C, rectal) was assured during the CPB. Four blood samples were drawn from the radial artery catheter immediately before starting CPB (T1), following protamine administration (T2) and at 24 (T3) and 48 h (T4) after completion of CPB. In each sample, creatine kinase-myocardial band (CK-MB), white blood cell (WBC), IL-6 and IL-8 levels were measured. IL-6 and IL-8 concentrations were measured by enzyme immunoassay and enzyme-linked immunoabsorbant assay methods. Serum IL-6 T2 and serum IL-6 T3 levels were significantly higher than IL-6 T1 levels in both groups (p < 0.001) and (p < 0.01), and there was no significant elevation in serum IL-8 levels in either group. Serum IL-6 levels were significantly higher in the placebo group than in the MPSS group at T3 (p < 0.009). There was no significant difference in CK-MB T1 levels between the groups. Although there was no significant difference between CK-MB T1 and T2 levels in the MPSS group, the CK-MB T2 and CK-MB T3 levels were significantly higher than T1 levels in the placebo group (p < 0.001) and (p < 0.05). There was significant elevation of WBC levels at T2 and T3 in both groups without notable difference between the groups (p < 0.05). This study has shown that low-dose MPSS suppresses CPB-induced inflammatory response. Further clinical studies (on larger and higher risk groups) may reveal more information on relations between morbidity and cytokine levels which may have some predictive value on clinical outcome following CPB.
