Twenty biochemical parameters have been studied in 94 athlets of Marcialonga in basic conditions and after 30 min from the end of the competition. Urea, uric acid, creatinin, total proteins, albumin, sodium, calcium, phosphorus and several enzymes (AST, ALT, LAD, CK and ALP) have shown statistically significant increasings. It is, above all, clear the increasing of CK. On the contrary triglycerides have undergone a significant decreasing. The AA. try to explain the results obtained, considering some pathogenetic theories.

Each of 5 groups of 50 weanling Wistar-derived female rats was fed a different diet ad libitum for 2 years. The diets included 3 commercial maintenance diets (R and M No. 1, R and M No. 491 and RDM 22), a purified or semi-synthetic diet (LJ 80) and the diet (LAD 2) normally used in this laboratory. A weighed amount of LAD 2 diet (less than would be consumed under ad libitum conditions) was fed each day to a 6th group of rats. The survivals of the groups of rats fed either the standard diet (LAD 2) in restricted amount or the maintenance diet (RDM 22) were 62% and 66% respectively and were significantly better than the 40% survival of the group fed LAD 2 ad libitum. The survivals of the groups fed either R and M No. 491 or LJ 80 were 40-42%, and the group fed R and M No. 1 had a survival of 52%. At the end of 2 years the 2 groups with the best (greater than 60%) survivals weighed significantly less than the group fed LAD 2 ad libitum. The groups fed either LAD 2 in restricted amount or RDM 22 had the least gross pathological lesions for the majority of the organs. These same groups also had fewer pituitary tumours per group (72% and 66%) than the group fed LAD 2 ad libitum (90%). The group fed RDM 22 also had the largest % (26%) of normal pituitaries of all the groups in the study. There were some significant differences between the haematological and clinical chemistry results of the group fed LAD 2 ad libitum and the other groups but none of the changes was considered adverse, although the groups fed either RDM 22 or R and M No. 491 had significantly increased mean aminotransferase (AST and ALT) values with large variations which were adjudged undesirable. There was less protein in the urine of the groups fed either RDM 22 or LAD 2 (restricted).

This study was undertaken to assess our experience with the first 50 patients who underwent CABG without cardiopulmonary bypass. In seven patients left internal mammary artery to left anterior descending artery (LIMA-LAD) grafting was performed through a short left anterior thoracotomy. In 43 other patients median sternotomy was used. Primary CABG was performed in 48 patients; there were two reoperations. Eleven patients had unstable angina. Three patients had left ventricular ejection fraction (LVEF) equal to or lower than 25%. One patient had carcinoma of the right lung coexisting with unstable angina and underwent also right lower lobectomy. In each patient the clinical course, 12-lead ECG, transthoracic echocardiography and the serum levels of creatine kinase (CPK), alanine aminotransferase (ALAT), aspartate aminotransferase (AspAT) were assessed. The need for inotropic or intraaortic balloon counterpulsation (IABP) support and blood transfusion was also recorded. There were three deaths, all in the sternotomy group (6%). A patient with systemic lupus erythemetodes (SLE) died of postoperative MI due to graft thrombosis. Another patient who was found to have porcelain aorta and had LIMA-LAD grafting as a rescue procedure died of MI with low cardiac output. The third patient with unstable angina and ejection fraction of 30% developed postoperative MI with ventricular arrhythmia. One patient with LIMA-LAD graft in whom percutaneous translaminal coronary angioplasty (PTCA) had been abandoned because of coronary spasm developed acute myocardial ischaemia 5 h postoperatively. He had a vein graft placed to LAD in cardiopulmonary bypass, his further course was uneventful. Six patients had IABP support. Nine patients needed inotropic support. Ten patients received blood transfusion. Twelve-lead ECG did not show acute ischaemia or MI, apart from the above described cases. Echocardiographic check showed improved IVS contractility in three patients and better apex motion in one case. In the other survivors the echocardiographic findings were the same as before the procedure. ALAT and AspAT serum levels were normal in all the survivors, and the CPK levels did not exceed 200 IU/ml. One patient from the mini-thoracotomy group had recurrent angina 2 months after the procedure. His left internal mammary artery (LIMA) graft was occluded; we replaced it with a vein graft. All 47 survivors remain asymptomatic, with the mean follow-up time of 6 months. Coronary surgery without cardiopulmonary bypass seems a valuable alternative for high-risk patients.
