Tissue Area

The fine structure of the lymphatic capillary and the surrounding tissue areas was investigated. Instead of a continuous basal lamina (basement membrane) surrounding the capillary wall, these observations revealed the occurrence of numerous fine filaments that insert on the outer leaflet of the trilaminar unit membrane of the lymphatic endothelium. These filaments appear as individual units, or they are aggregated into bundles that are disposed parallel to the long axis of the lymphatic capillary wall and extend for long distances into the adjoining connective tissue area among the collagen fibers and connective tissue cells. The filaments measure about 100 A in width and have a hollow profile. They exhibit an irregular beaded pattern along their long axis and are densely stained with uranyl and lead. These filaments are similar to the microfibrils of the extracellular space and the filaments observed in the peripheral mantle of the elastic fibers. Infrequently, connections between these various elements are observed, suggesting that the lymphatic anchoring filaments may also contribute to the filamentous units of the extracellular space. It is suggested that these lymphatic anchoring filaments connect the small lymphatics to the surrounding tissues and represent the binding mechansim that is responsible for maintaining the firm attachment of the lymphatic capillary wall to the adjoining collagen fibers and cells of the connective tissue area.

Anatomical Finding

An anatomical study of 50 fresh adult human cadavers was performed in order to verify prevalence of Galen’s anastomosis (GA) and to evaluate whether factors such as gender, ethnicity, side of the neck, and individual stature may interfere with GA prevalence. The results were analysed using the Chi-square test, Student t-test, and F-Snedecor test. GA was observed in 87 of 100 dissections. There was no statistically significant difference regarding GA prevalence between groups separated by ethnicity (p = 0.853), gender (p = 0.198), side of the neck (p = 0.766), or individual height (p = 0.199). Therefore, the GA was a frequent anatomical finding, and this result was not influenced by any studied factor. Comparing our data with previous studies, we also concluded that the GA seems to play an important role in the innervation of the larynx, even though its function remains unclear. Also, it is reasonable to consider GA a constant anatomical constituent.

Objective. To explore the effect and mechanism of the sponge dressing on the healing of refractory orthopedic wound, and the gelatin-Bletilla striata gum/Salvia miltiorrhiza nano Ag (GBS-Ag) sponge dressing was prepared. Methods. GBS-Ag sponge dressing was prepared by the freeze-drying method. Twenty male SD rats were randomly divided into the control group (Ctrl group) and GBS-Ag group, with 10 rats in each group, and the rats in the two groups were established a model of back wound infection. The Ctrl group was treated with gauze, while the GBS-Ag group was treated with GBS-Ag sponge dressing. Wound healing rate, blood immune indexes, Ag content in each organ, morphological changes of wound, and expression of transforming growth factor-β1 (TGF-β1) in wound transformation were detected in the two groups of rats. Results. The mechanical properties of GBS-Ag sponge dressing were all in line with the standard, and it had good killing effect on the conventional strain after being incubated for 24 hours. Compared with the Ctrl group, the healing rate and lymphocyte percentage in the GBS-Ag group were significantly increased on day 4 and day 10 ( P < 0.05 ), while the total number of white blood cells and the percentage of neutrophils were significantly decreased ( P < 0.05 ). Compared with Ctrl group, the Ag content in liver, spleen, and kidney of rats in the GBS-Ag group was significantly increased ( P < 0.05 ). The histological results showed that the Ctrl group lacked collagen fibers in the dermis, and the angiogenesis was not rich, accompanied by a large number of inflammatory cell infiltration. The epidermal repair of rats in the GBS-Ag group was complete and partially keratinized, the dermis was rich in collagen fibers, with elastic fibers and new blood vessels, inflammatory cells were rare, and new hair follicles and thick-walled blood vessels were also observed. The expression of TGF-β1 protein in the wounds of rats in the GBS-Ag group was higher than that of the Ctrl group. Conclusion. GBS-Ag sponge dressing had multiple effects of sterilization and promoting wound healing, and its mechanism may be related to promoting the TGF-β1 protein expression.

PURPOSE: Analysis of ossification, bone marrow formation, perichondrium thickness, muscle fibers, collagen fibers and elastic fibers quantities of cricoid and arytenoid cartilages. Design: Correlation morphologic study. METHODS: Twenty-four cricoarytenoid joints were obtained from Caucasian male fresh cadavers divided into three groups with eight specimens in each: group I - adolescents, from 15 to 20; group II - adults, from 25 to 35; and group III - elderly, from 60 to 75. The specimens were stained with H-E; trichrome; Picrosirius; and elastic stain. Histometry was performed for quantitative analysis. Bonferroni Test, Fisher Test and the Variance Analysis were used. RESULTS: At the microscopic analysis, the group I specimens presented typical hyaline cartilage, thin perichondrium, bulky muscle fibers and were surrounded by collagen fibers. In group II, there were ossification in small well defined central areas of four specimens, with lamellar bone tissue. In two of these cases there were central bone cavity full of fat tissue. The other parameters were similar to group I. In group III, most part of hyaline cartilage was replaced by typical lamellar bone tissue with poorly outlined haversian systems. Hematopoietic tissue was noted in six cases and fat tissue in the other two. Perichondrium was thicker. Small muscle fibers were smaller and surrounded by collagen in great quantity. Elastic fibers were present in small quantity in the outer portion of perichondrium in all the groups. CONCLUSIONS: In spite of its lack in adolescence, ossification occurs in cricoid and arytenoid cartilages during adulthood and intensifies with age; bone marrow is formed in ossification tissue with hematopoietic tissue in group III; perichondrium becomes thicker in group III; muscle tissue atrophies in group III and is replaced by collagen fibers; these fibers thicken with age; and elastic fibers is always present in the perichondrium in low quantity.
