Histologic Changes

The research deals with the study of histomorphologic changes in the lymph nodes of rats arising from the lymphotropic and intramuscular administration of acidic peptidoglycan. The authors investigated histologic changes and applied the morphometric method including the determination of the average size of the lymph nodes, the size of the germinal zones, the density of the lymph nodules. It is stated that the restructuring of the lymph nodes during lymphotropic administration occurs at different times in comparison with its intramuscular administration. The lymphotropic method provides a relatively earlier and prolonged onset of an immunostimulating effect. This made it possible to conclude that the method of administering immunomodulators should differentiate depending on the phase and form of the disease progression.

In this retrospective study, radiographically enlarged sternal lymph nodes (LNs) were evaluated in 71 dogs and 13 cats for average size, location, and most representative radiographic view. Concurrent clinical diagnoses were also noted and grouped into one of three following categories: neoplastic, inflammatory, or hematologic. There were no statistically significant differences in LN size between lateral views within each species. Enlarged sternal LNs were more cranially positioned in dogs than cats. No statistical difference was noted between right and left laterals, as to on which projection the enlarged sterna lymph nodes was seen best. Neoplastic disease (78.9%) was the most prevalent condition seen in association with LN enlargement in dogs, followed by primary infectious or inflammatory diseases (14.1%) and various hematologic conditions (7.0%). In cats, neoplasia was also most common (69.2%), followed by inflammatory diseases (30.8%). No hematologic conditions were noted in cats. The most common etiologic agent seen concurrently with enlarged sternal LNs in both dogs (33.8%) and cats (38.5%) was malignant lymphoma. The results of this study provide a clinically useful representation of the average size and location of radiographically enlarged sternal LNs for dogs and cats. The diseases represented demonstrate the wide spectrum of potential causes of sternal lymphadenopathy.

Amylase Isoenzymes

Abstract I report a direct, sensitive, quantitative method for determining serum amylase isoenzyme activity with commercially available reagents. Day-to-day reproducibility (CV) was 3--4% for the isoenzymes in normal serum; within-run precision was 8, 3, and 2% for low, normal and high isoenzyme activities. Amylase isoenzymes, separated into the pancreatic and salivary types by electrophoresis in polyacrylamide gel, are then quantified by directly incubating the gels in soluble-starch solution, staining with iodine, and densitometry. The proportion of pancreatic isoenzyme (47 normal sera) was 43 +/- 8% (mean +/- SD). Isoenzyme activities as low as 2% of normal can be measured accurately in 10 micro L of serum. The reproducibility, precision, and sensitivity indicate that the method is applicable to differential diagnosis of hyperamylasemia or hypoamylasemia, and is suited for monitoring the subtle changes in serum amylase isoenzyme distribution that may accompany disease progression or therapy.

And Function

ABSTRACT An average size chromomere of the polytene X chromosome of Drosophila melanogaster contains enough DNA in each haploid equivalent strand to code for 30 genes, each 1,000 nucleotides long. We have attempted to learn about the organization of chromosomes by asking how many functional units can be localized within a chromomere. This was done by 1) recovery of mutants representative of every cistron in the 3A2-3C2 region; 2) the characterization of the function of each mutant type and grouping by complementation tests; 3) the determination of the genetic and cytological position of each cistron by recombination and deletion mapping. The data clearly show one functional group per chromomere. It is postulated that a chromomere is one cistron within which much of the DNA is regulatory in function.

High Histologic Grade

The immnuohistochemical determination of immunoglobulins IgA, IgG and IgM in axillary lymph nodes from 50 unselected breast ductal carcinomas disclosed that lymph nodes with IgG-positive lymphoid follicles and/or metastasized lymph nodes with IgM-positive lymphoid cells are statistically related to breast tumors with a high histologic grade and more than 3 lymph node metastases.
