The article presents the remote results (time-period more than 1 year) of application of percutaneous laser destruction in treatment of nodular goiter in 164 patients. The reliable decreasing of dimensions and size of nodular formations of thyroid gland in early time-periods with continuation of regression during a year is established. In the following, slight regression was marked during 3,5-5 years. The morphological analysis established that in remote time-periods after percutaneous laser destruction of nodular proliferating colloid goiter the destroyed follicular epithelium and colloid are replaced by connective tissue structures with large amount of collagen guaranteeing long-term predictive result.

We investigated two structures that are in close association with the pyramidal lobe of the thyroid gland. Our investigation was performed using microdissection and histological examination in 106 human postmortem specimens. The first investigated structure was identified as the thyroid fibrous band that was present in 28.3% of cases. This band was always associated with the pyramidal lobe (which was significantly longer and thicker when associated with this band) and it had a constant hyo-pyramidal extension; it was located close to the midsagittal plane and predominantly composed of dense irregular connective tissue. The second investigated structure was the levator glandulae thyroideae muscle, which was associated with the pyramidal lobe in only 13.6% of cases. This muscle had a double extension, hyo-pyramidal and laryngo-pyramidal, located farther from the midsagittal plane, it was longer and thinner than the thyroid fibrous band and predominantly composed of striated muscle fibers. We confirmed our hypothesis that the thyroid fibrous band, which may be considered as the partial fibrous remnant of the thyroglossal duct and levator glandulae thyroideae, and which may be considered as infrahyoid or laryngeal muscle, are two different structures of the thyroid gland.

 The thyroid gland of Moorhen has two separated lobes. These lobes were located in the throracic inlet and receive blood supply from the cranial, middle and caudal thyroid arteries. The histological organization of the thyroid gland in Moorhen is surrounded by a distinct connective tissue capsule and the parenchymal cells were arranged into colloid filled follicles enmeshed in the highly vascular interstitial connective tissue. The bilaterally paired, round to oval, parathyroid glands in Moorhen were located intrathoracically near or close to the caudal pole of the thyroid glands. They receive blood by short branches from caudal thyroid artery and small branch from the common carotid artery. The parathyroid glands in Moorhen have a thin connective tissue capsule. Its parenchymal cells were arranged into an irregular, anastomosing cords of chief cells. No oxyphil cells were found in the parathyroid glands of Moorhen.

A new staining technique has been developed for the thyroid gland involving the use of two components of the Mallory connective tissue stain, aniline blue and orange G in reversed proportions.Various indices such as incorporation of radioiodine, epithelial cell height, and number of blue and yellow staining follicles and total number of follicles have been used to test the validity of the color reaction in the colloid. The comparison of these diverse indices strongly suggests that the colloid material which stains with aniline blue corresponds to iodinated thyroglobulin, while the yellow staining material appears to be devoid of biologically active iodinated amino acids.

The discovery of the parathyroid gland by the Uppsala anatomist Ivar Sandström (Figure 1) is often called the last anatomical discovery. That remarkable discovery was made in 1877 at the Anatomical Department in Uppsala. At that time Sandström was a young medical student, who had worked as an assistant at the department since 1873. His discovery was published in Upsala Läkareförenings Förhandlingar, in 1880 (1). His publication was in Swedish, and the paper was entitled ‘On a New Gland in Man and Several Animals’. The article comprised 30 pages, and in the introduction Sandström writes: Almost three years ago I found on the thyroid gland of a dog a small organ, hardly as big as a hemp seed, which was enclosed in the same connective tissue as the thyroid, but could be distinguished therefrom by the light colour

Hyperplastic Parathyroid Gland

The occurrence of the extracellular, banded or cross-striated material has been reported in many types of tissues. It generally appears as scattered fusiform strands showing cross-banding with a periodicity of 1000 to 1500 Å as well as delicate longitudinally oriented elements. Such a banded structure (BS) first noted by Luse in a neural tumor, was confirmed by others. Similar structures have more recently been found in a variety of organs both human and animal. In our own experience they were seen in a hyperplastic parathyroid gland, follicular adenoma of thyroid gland, sarcoidosis of lymph node and in non-specific demyelinization of nerves. We should add that to our knowledge, BS has not been previously reported in the parathyroid gland or thyroid gland.

History Of

The quantitative determination of the content of radioactive iodine in the urine for the evaluation of the functional state of the thyroid gland was first introduced into clinical practice by J. Hamilton in 1939, and in 1942 he developed a method for determining the content of radioactive iodine directly in the thyroid gland, and in the same year reported experiment on a dog who was injected with a large dose (300 μCi per 1 g of body weight) of radioactive 1311, which caused complete destruction of the thyroid gland with complete replacement of its structure with connective tissue with complete safety araschitovidnyh glands. By 1950, there were already many works devoted to this topic. In the mid-50s, such works began to appear in Russia. Among them, one can note the research of M. N. Fateeva (1953), V. K. Modestov (1958), A. 3. Tsfasman (1961), P. I. Egorov (1961), N M. Draznina (1961) and others, but this problem is most fully reflected in the domestic literature in the writings of prof. V. G. Spesivtseva [1-3].

The Mean

The histometric and histologic standard techniques were used to provide comprehensive information on the morphological changes in the thyroid gland of West African Dwarf goat during the foetal and postnatal development stages. The foetal age was determined using crown rump length and the pre-pubertal and pubertal age of animals was determined by dentition. The early foetal thyroid, surrounded by a thin capsule of dense irregular connective tissue, was continuous with well vascularised loose connective tissue septa. The parenchyma was composed of solid cell clusters of follicular epithelial cells surrounding small lumina. Follicular arrangement was indistinct in foetal thyroid by 50-70 days of gestational age and many follicles of different sizes were present by 95-125 days onwards. Significant variations in the mean follicular diameter, mean capsule thickness and mean epithelial cell height of the thyroids were observed in all stages of development. The mean large follicular diameter in the foetal, pre-pubertal and pubertal ages were 17.70 ± 0.09 µm, 54.41 ± 0.28 µm,142.77 ± 0.51 µm respectively. The follicular cells were of low cuboidal shape in foetuses, assumed high cuboidal or columnar form in pre-pubertal group and squamous in older pubertal age. Ultimobranchial follicles were encountered in early foetal goat thyroids, while focal areas of follicular cell hyperplasia were frequently seen in the older pubertal thyroids. The strong PAS-positive reaction increased strikingly from the 95-125 days foetal age, and by pubertal age all follicles were fully distended with colloid. Colloid vacuolation (colloid droplets) were encountered frequently by the age of 95-125 days, indicating the ability to synthesize hormones towards the last trimester of gestation. Parafollicular cells were distinguished by its pale cytoplasm and large nucleus at 75-90 days onwards. They were located basally and as clusters in the interfollicular tissue. This finding suggested possible high prenatal function for the thyroids of goats in the synthesis of thyroid hormones.
