Modification of muscle-preserving radical mastectomy.

A technical improvement of the muscle-preserving radical mastectomy for breast cancer is presented. In this procedure, the Sulcus interpectoralis, located between clavicular and sternocostal parts of the pectoralis major muscle, is split bluntly and spread apart. Then, the pectoralis minor muscle is severed near its attachment to the coracoid process and an axillary dissection is thereby easily and thoroughly accomplished. The effectiveness of lymph node dissection by this method was ascertained when the number of the lymph nodes removed by this procedure was compared with that removed by the conventional muscle preserving mastectomy (Madden's operation) and the radical mastectomy. Ninety-three patients treated by this operation have shown a satisfactory cosmetic appearance and a good prognosis when compared with patients treated by the standard radical mastectomy.

Alterations of the thymus and peripheral lymphoid tissues in fatal measles. A review of 14 autopsy cases.

As a result of re-examining 14 autopsy cases of fatal measles, neither aplastic nor hypoplastic thymuses were found even in a case with giant cell pneumonia, but there were degenerative and/or necrotic changes with giant cells mostly in the thymus and less in the peripheral lymphoid organs such as spleen, lymph nodes, Peyer's patches and tonsils. This damage of the lymphoid system was associated with the occurrence of complications, particularly of giant cell pneumonia and encephalitis. The lymphoid cell damage, which might be primarily due to virulence of the infected measles virus, seemed to prolong the viremia. Involvement of viremia in the process of complication is discussed.

Insulin and glucagon secretion in hepatic glycogenoses.

Insulin and glucagon secretion was investigated in ten patients with hepatic glycogenosis, types I and III, in order to understand the relationship between hypoglycemia and pancreatic function. In all patients, both oral glucose tolerance and intravenous arginine infusion tests revealed hypoinsulinemia. Decreased urinary C-peptide levels with standard food intake also supported hypofunction of pancreatic beta cells. On the contrary, the normal secretion pattern of glucagon in both types indicated in the arginine loading test, intact alpha cells in the pancreas. Persistent hypoinsulinism, which is apparently an adaptation to hypoglycemia, could be an important cause of nutritional dwarfism in both types of glycogenosis. The usefulness of the measurement of urinary C-peptide, which evaluates the pancreatic function and provides management for normal body growth, is discussed.

Inhibitory effects of macrophages against Marek's disease virus plaque formation in chicken kidney cell cultures.

Inhibition of plaque formation by Marek's disease virus (MDV) in chicken kidney cell cultures was investigated with the use of peritoneal exudate cells (PEC) from chickens. PEC from MDV-infected White Leghorn chickens inhibited the formation of MDV plaques, whereas the inhibitory effect of PEC from chickens vaccinated with herpesvirus of turkey (HVT) or PEC from normal chickens was very weak. However, PEC from either normal chickens or HVT-vaccinated chickens inhibited the MDV plaque formation in the presence of serum from MDV-infected chickens but not from normal or HVT-vaccinated chickens. The capacity of PEC to inhibit plaque formation was significantly reduced when PEC was treated with carrageenan but not with antithymus or antibursa cell serum. These results indicate that macrophages may have a role in protection against Marek's disease by reducing the number of MDV-infected cells and thereby decreasing the spread of the virus in vivo.
