Healing Processes

ABSTRACT Biochemical and histological changes in the aortic wall of rabbits were demonstrated following injection of epinephrine and l-thyroxine during 2 weeks. The widespread gross and microscopic changes were accompanied by an increase in hexosamine content and uptake of 35S labeled sodium sulphate, and an increased calcium content, whereas the collagen content, assessed by determination of hydroxyproline, was reduced. Comparison with the effect of epinephrine injections alone showed that thyroxine intensified the damaging effect of epinephrine on the vessel wall and induced more pronounced mucopolysaccharide changes in the aortic wall, presumably acting as a link in the healing processes.

Synergetic Action

ABSTRACT In all previous investigations on experimental exophthalmos, heterologous thyrotrophic pituitary extracts have been used. These protein hormones stimulate antihormone formation in the test animals. Cortisone has been reported to effectively block antibody formation. In addition, it has been shown to potentiate TSH-induced exophthalmos in guinea-pigs. With rabbits as test animals, the hexosamine content of the orbital tissues was determined and used as an index of exophthalmos development and at the same time the antibody titres in the sera were followed. TSH injections for six weeks led to a highly significant accumulation of hexosamine in the retrobulbar connective tissue and in the extraocular muscles, i. e. an increase of up to 400% as compared with the control animals. At the same time a significant rise in antihormonal titres was detectable in the sera. Concomitant treatment with cortisone brought about an equal or higher accumulation of hexosamine but significantly lower antibody titres. The known opposite peripheral actions of TSH and cortisone can be reconciled with the synergy in producing experimental exophthalmos by attributing the synergetic action of cortisone to the blocking of antihormone formation. If less antihormones are produced, the effect of TSH is enhanced. Our experiments do not provide direct proof for this hypothesis. High hexosamine values in the orbit and low antihormone titres in the serum are, however, concomitant phenomena.

Hexosamine Content

Leaves of 20 species contained both polymer-bound and 80%-acetone-soluble forms of hexosamine. Similar amounts of polymer-bound hexosamine (about 1.9 μg/mg protein) were found in all the leaves, suggesting that it may be an essential element of membrane structure.

Hexosamine Content

The concentration of total hexosamine (as free base) in the dry matter of tissues of the pullet was high in cartilage (8.0 mgm. per gm.) and in oviduct (6.4 mgm. per gm.); medium in comb and wattles, tendon, and lungs (3.0 to 5.5 mgm. per gm.); and low in voluntary muscle (1.5 mgm. per gm.). Dry defatted skin contained 8.3 mgm. per gm. Total serum hexosamine was 52 mgm. per 100 ml. and was increased significantly to about 67 mgm. per 100 ml. by treatment with estradiol benzoate (ODB) and to about 72 mgm. per 100 ml. by ODB plus testosterone propionate (TST). Serum protein was also increased significantly by the hormonal treatments, but to a relatively greater extent. The magnum of the hypertrophied oviducts of pullets treated with ODB was relatively high in dry matter (22.0%), and this dry matter was relatively rich in hexosamine (13.8 mgm. per gm.) and low in hydroxyproline (2.9 mgm. per gm.). The dry matter of the uterus and vagina was relatively low in hexosamine (6.0 mgm. per gm.) and rich in hydroxyproline (5.7 and 10.5 mgm. per gm. for uterus and vagina respectively). Concurrent administration of ODB and TST led to a greater degree of hypertrophy of the oviducts than did administration of ODB alone; both the weight and total hexosamine content of the magnum showed a greater relative increase than did the values for vagina and uterus. Some modifications of the method of determining the hexosamine content of tissues are described.
