In the mixed body lymph of the thoracic duct and in the defined organ lymph of the liver and the intestine, the catalytic activity concentrations of up to sixteen enzymes and the concentrations of albumin and protein were determined, as well as the transport rate of these substances and their lymph/plasma ratio. Thoracic duct lymph specimens were obtained from an extracorporeal lymph shunt in anaesthetized and conscious dogs and from short-term fistulas in anaesthetized rabbits, rats and mice. Additionally, rabbits and rats underwent passive motion of the hind limbs in another experimental trial. Thoracic duct flow in anaesthetized dogs is only half that seen in conscious dogs, due to bypassed muscular lymph. A similar flow change is seen during passive motion of hind limbs in anaesthetized rabbits and rats. From a literature review of flow in the four main lymphatics of the body, it is concluded that the thoracic duct flow should account for 50-70% of total body lymph flow. In the anaesthetized state, flow is mainly of visceral origin. In the conscious state and during passive motion the increased flow is of muscular origin. In the latter case, the catalytic activities of enzymes like lactate dehydrogenase, malate dehydrogenase, creatine kinase, aldolase and phosphohexose isomerase, increase in lymph as does their lymph/plasma ratio. These enzymes have high catalytic activities in muscle. Their transport into the blood increases 2-3-fold, due to a doubling of lymph flow. Reported data for anaesthetized and immobile animals therefore far underestimate the significance of thoracic duct enzyme transport. Liver lymph was obtained from anaesthetized dogs and rabbits. Our finding that lymph catalytic activity for several enzymes is higher than in plasma is not compatible with the proposed delivery of plasma proteins directly into the sinusoidal space without prior mixing with the Space of Disse. Enzymes in liver lymph should derive from parenchymal and endothelial lining cells. Their site of delivery from the hepatocyte seems different from that of proteins. Liver lymph is an important transport route of enzymes into the blood. Intestinal lymph was sampled from anaesthetized dogs, rabbits and rats. It was shown that most enzymes from the intestine are primarily released into the interstitial space and from there are transported via the lymph into the blood.

A 70-year-old man with lung cancer was scheduled for partial resection of the right lung. Preoperative serum creatine kinase was elevated (1808 IU x l(-1), CK-MM 97%). Acute coronary syndrome was denied by the absence of significant stenosis of coronary artery and the normal segmental wall motion in echocardiography. The other examinations did not reveal the cause of CK elevation. He did not receive dantlorene preoperatively, but the surgical procedure was performed uneventfully without the use of the triggering agents, such as volatile inhalational anesthetic gases and suxamethonium. Thoracic wall was not invaded by the tumor. After the operation, CK went down quickly. It decreased further after the postoperative chemotherapy. We concluded that CK elevation might have been produced by adenocarcinoma itself, judging from the rapid decrease after surgery and the absence of thoracic wall invasion. Though CK elevation may indicate the malignant hyperthermia, we should not delay the surgery too long when there is possibility of CK elevation derived from cancer itself.

Aprotinin is widely used in cardiac surgery to reduce postoperative bleeding and the need for blood transfusion. Controversy exists regarding the influence of aprotinin on renal function and its effect on the incidence of perioperative myocardial infarction (MI) and cerebrovascular incidents (CVI). In the present study, we analyzed the incidence of these adverse events in patients who underwent coronary artery bypass grafting (CABG) surgery under full-dose aprotinin and compared the data with those recently reported by Mangano et al [2006]. For 751 consecutive patients undergoing CABG surgery under full-dose aprotinin (>4 million kalikrein-inhibitor units) we analyzed in-hospital data on renal dysfunction or failure, MI (defined as creatine kinase-myocardial band > 60 iU/L), and CVI (defined as persistent or transient neurological symptoms and/or positive computed tomographic scan). Average age was 67.0 +/- 9.9 years, and patient pre- and perioperative characteristics were similar to those in the Society of Thoracic Surgeons database. The mortality (2.8%) and incidence of renal failure (5.2%) ranged within the reported results. The incidence rates of MI (8% versus 16%; P < .01) and CVI (2% versus 6%; P < .01) however, were significantly lower than those reported by Mangano et al. Thus the data of our single center experience do not confirm the recently reported negative effect of full-dose aprotinin on the incidence of MI and CVI. Therefore, aprotinin may still remain a valid option to reduce postoperative bleeding, especially because of the increased use of aggressive fibrinolytic therapy following percutaneous transluminal coronary angioplasty.
