The widespread contamination of the environment with PCB, a compound used extensively by industry in hydraulic and heat transfer fluids as well as plasticizers and solvents in adhesives and sealants, has resulted in detectable tissue levels in a large portion of the human population, domestic animals, and wildlife. Intoxication with PCB produces severe hepatic necrosis, degeneration of lymphoid tissues and kidney, skin lesions, decreased reproductive performance, reduced feed efficiency, and decreased weight gain. PCB also has been reported to reduce the binding of thyroid hormone to serum proteins and enhance the peripheral metabolism of thyroxine with increased excretion of thyroxine-glucuronide in the bile (Bastomsky, Endocrinology 95: 1150-1155, 1974).The objectives of this investigation were (1) to investigate the histopathologic, histochemical, and ultrastructural changes in thyroid FC produced by the acute (4 week) and chronic (12 week) administration of low (50 ppm) and high (500 ppm) doses of PCB to rats, (2) to correlate these alterations to changes in serum immunoreactive thyroxine concentration, and (3) to investigate the persistence of the effects of PCB on the thyroid gland.

SummaryLaser nephelometry is a technique which allows the evaluation of the concentration of several serum proteins and clotting factors. By means of this technique it is also possible to study the kinetics of the reaction between antigen and antibody. We studied the kinetics of the reaction between prothrombin and an antiprothrombin antiserum using several prothrombins namely: Prothrombin Padua, prothrombin Molise, which are two congenital dysprothrombinemias, cirrhotic, coumarin or normal prothrombins. Different behaviors in the kinetics of the reactions were shown even when the concentration of prothrombins was about the same in all plasma tested. These differences were analyzed by means of a computer (Apple II 48 RAM) programmed to solve four unknown equations (Rodbard’s equation). From the data so obtained one can see that when voltages at the beginning and at the end of the reaction are in all cases about the same, a clear difference in the time required to reach half the maximum value of the voltage can still be demonstrated. This parameter, which is expressed in minutes, is longer in coumarin and prothrombin Molise than in controls. On the contrary it is shorter in prothrombin Padua and has about the same value of controls in the cirrhotic patient. Moreover the time at which the maximum rate is obtained is longer in coumarin and prothrombin Molise than in controls and shorter in liver cirrhosis and prothrombin Padua. In conclusion data obtained show that coumarin prothrombin behaves in a different way from cirrhotic prothrombin and also that there is a different behaviour between the two congenital dysprothrombinemias.

ABSTRACT A type of subacute thyroiditis occurring epidemically in a factory in Helsinki was observed in 44 cases. In every case the thyroiditis followed an acute infection of the upper respiratory tract. The variation in incidence during one and a half years was in good agreement with that of the acute infection. Since Helsinki is in an endemic goitre region, the fact that the disease was of the migrating type was of great diagnostic importance. In all cases but one, the nodules have persisted. One case of asymptomatic thyroiditis was seen. In the majority of the patients the thyroid gland had been carefully palpated before the thyroiditis occurred, and in all cases the condition was followed up by the same investigator. Special attention was paid to changes in the iodine metabolism, the serum cholesterol, the electrophoretic distribution pattern of the serum proteins, and the circulating thyroid auto-antibodies. In many cases needle biopsy of the thyroid gland was performed. Thyroid function invariably returned to normal with time, although one patient remained in a hypothyroid state for about a year. In no cases were thyroid auto-antibodies found. For the beta-globulin fraction, the electrophoretic distribution pattern of the serum proteins gave values which were still not normalized in any case, and only in two cases was the alpha2-fraction normalized. The needle biopsy, when thyroid tissue was obtained, showed almost the same picture as in endemic goitre, but in some specimens nonspecific inflammatory changes were seen. Prednisolone relieved the symptoms, but did not affect the course of the disease. According to the present observation this type of epidemic thyroiditis would seem to represent a form of nonspecific subacute thyroiditis.

ABSTRACT The percentage of LH* bound to antibodies that have been covalently bound to cellulose is diminished in the presence of LH-free human serum and sera from various species of animals. Serum fractionation studies on Sephadex G 200 show that the greatest interference comes from the proteins eluted in the void volume i. e. the high molecular weight proteins. Specifically, the gamma M globulins and the α2-macroglobulins appear to play an important role, as demonstrated by tests in which these proteins were neutralized by gamma M and α2-macroglobulin antisera.

Iodine Metabolism

ABSTRACT A series of cases of clinically diagnosed subacute thyroiditis comprising 11 patients is reported. Studies on the iodine metabolism, electrophoretic distribution of the serum proteins and the responsiveness to TSH were carried out. The patients were observed for periods up to 16 months from the onset of the disease. In the early phase there was an elevation of the serum PBI in a few cases and hyperthyroid signs in some, accompanied by depressed thyroid uptake of radioactive iodine and a fairly good response to TSH. Later, the thyroid grew hard and the iodine metabolism changed. In several cases there was a marked increase in the conversion ratio and the serum PB131I level. The responses to TSH was variable for different parameters of thyroid function, suggesting a state of »low thyroid reserve« as defined by Jefferies et al. (1956). Hypothyroidism developed in 3 cases; in two of them there was a response to exogenous TSH, in the third no response was seen at this stage of the disease. Cortisone and synthetic analogues seem to be of great benefit in the treatment of the acute symptoms of the disease.
