Question: Abstract: Both heparin and fibrinolytic agents carry a risk of bleeding. Because of their beneficial effects in restoring vessel patency, we prefer the use of fibrinolytic agents in patients with acute deep vein thrombosis unless there is some specific contraindication. With the treatment regimen we have outlined, the risk of bleeding is extremely low. We have found that the long-term results achieved with streptokinase therapy are excellent, and normal venous hemodynamics can be restored quickly and effectively.

Answer: Bandages

Question: Abstract: Neutron Activation Analysis (NAA) was used to investigate trace element patterns in serum, packed cells, and dialysate of CAPD patients. The concentrations of the elements Cs, Cu, Fe, and Mn in serum and packed cells appeared to be maintained within the normal range, while the levels of the non-essential element Br in both serum and packed cells were subnormal. The serum Cr values were extremely high (20 to 50 times higher than the normal serum level). The amount of Cr absorbed from the dialysate was calculated to be ten times higher than the daily dietary uptake. The Co concentrations were normal in packed cells but were significantly increased in serum. The Rb content in packed cells was slightly lower than normal, while the serum value was normal. Se was maintained within the normal range in packed cells, but the serum concentration was slightly lower than normal. The concentrations of Zn were low in serum and appeared to be higher than normal in packed cells. In conclusion, this analysis of the trace element status of CAPD patients reveals two major abnormalities. There is an apparent loss of Br from the blood towards the dialysate and on the other hand, a dramatic accumulation of Cr into the blood as a result of the very high Cr content in the dialysate.

Answer: Comparative Study

Question: Abstract: Patients with exocrine pancreatic insufficiency may absorb greater than 50% of dietary fat despite the absence of measurable pancreatic lipase activity. Nonpancreatic lipolytic activity was measured in gastric and duodenal aspirates from 5 patients with exocrine pancreatic insufficiency secondary to alcoholism and in aspirates from 5 alcoholics without evidence of exocrine pancreatic dysfunction (controls). Samples were collected under fasting and postprandial conditions. All patients with exocrine pancreatic insufficiency had nonpancreatic lipolytic activity in gastric and duodenal aspirates. Lipolytic activity in gastric aspirates was not significantly different between the patients with exocrine pancreatic insufficiency and the controls during the fasting and postprandial periods. Pancreatic insufficiency was associated with significantly (p less than 0.05) higher nonpancreatic lipolytic activity in the duodenum under fasting conditions. No significant difference between the groups was found in postprandial nonpancreatic lipolytic activity. Nonpancreatic lipolytic activity accounted for approximately 90% of total lipolytic activity at the ligament of Treitz in patients with exocrine pancreatic insufficiency as opposed to 7% in the control subjects. These observations suggest a significant role for nonpancreatic lipolytic activity (lingual lipase and gastric lipase) in fat digestion in patients with pancreatic insufficiency secondary to chronic alcohol abuse.
