Abstract
UNLABELLED The aim of the study was to estimate the dose of thyroxine required by pregnant women who had undergone total thyreoidectomy and radioiodine treatment for thyroid cancer. Material consisted of 4 pregnant women, aged mean 30.8 years. One of patients was studied during 2 consecutive pregnancies. The daily mean dose of thyroxine was 175 micrograms. The control group consisted of 7 women with primary hypothyroidism aged mean 33.5 years, who were treated with replacement doses of thyroxine. One of them was pregnant twice. The mean daily dose of thyroxine was 106.3 micrograms. The estimation of TSH, fT4 were repeated every 4 weeks. RESULTS In all cases natural deliveries took place. All infants were alive and had no congenital malformations and no clinical or biochemical thyroid dysfunction was found. Pregnant women treated for thyroid cancer needed to have optimized their suppressive therapy by increasing the dose of thyroxine by 26% at the first trimester, 27% at the second and 38% at the last one. Statistically significant increase was found at the 1st trimester of pregnancy and it remained at the same level till the delivery. Pregnant hypothyroid women needed to have optimized their replacement thyroxine therapy by increasing of the dose by 53% at the first trimester, by 49% at the second and by 53% at the last one. Similarly to the 1st group of patients, we noticed statistically significant increase at the 1st trimester of pregnancy. CONCLUSION In pregnant women who have been previously treated for thyroid cancer the suppressive dose of thyroxine needs to be increased by 26-38% which is slightly less than the increase of the replacement dose in hypothyroid pregnant women.

Abstract
Total thyroidectomy followed by 131I ablation and thyroxine suppressive therapy is recommended for the treatment of differentiated thyroid carcinomas. Thyroxine should be given at a dose sufficient to suppress TSH to low or undetectable levels. These patients are categorized as subclinical hyperthyroidism subjects. Some cardiovascular effects of subclinical hyperthyroidism, such as an increase in left ventricular mass and accelerated bone loss, should be taken into consideration. Estrogens reduce the loss of bone mass in thyrotoxic postmenopausal patients and have cardioprotective effects. The relatively high incidence of thyroid carcinoma in women suggests that estrogen and/or progesterone may be important for the development of these neoplasms. Immunohistochemical study has established that steroid receptors are present in thyroid tissue. Many authors suggest that estrogens by itself do not appear to affect the natural history of thyroid cancer. Besides the thyroid, active iodide transports catalysed by the sodium/iodide symporter occurs in the lactating mammary gland. An increased risk of breast carcinoma in women with thyroid carcinoma due to carcinogenicity of radioiodine has been reported by some but not all investigators. Hormone replacement therapy in the thyroxine treated postmenopausal women consists in conventional oral or transdermal estrogen combined with progesterone. In some cases the daily dose of thyroxine should be increased to achieve TSH suppression.

Abstract
Women surviving breast cancer in the postmenopausal period suffer from hormonal alternations with adverse effect on mental status and functioning of a number of organs and systems. Two thirds of these women had menopause before the diagnosis of breast cancer. In the remaining one-third ovarian failure is natural or induced by chemotherapy. Doctors cautiously approach the use of estrogen therapy in this group of patients. Their fears are not unsupported bearing in mind known epidemiological data exist linking breast cancer with the use of hormonal therapy. The purpose of this review is to evaluate current data on hormonal use and breast cancer risk.

Abstract
A typical three generation-family with MEN 2A (Multiple Endocrine Neoplasia, Type 2A) is described. Two brothers and their uncle were affected with medullary thyroid carcinoma (MTC) and pheochromocytoma. The diagnosis of MTC was based on calcitonin determinations after pentagastrin stimulation. Pheochromocytoma was clinically silent in two cases. A family screening with pentagastrin test led to the diagnosis of C cell hyperplasia in a 8-year boy, who was then successfully operated on. The authors discuss the value of pentagastrin test and genetic testing in the early diagnosis of MTC associated with MEN 2A syndrome.

Abstract
UNLABELLED The relationship of growth hormone (GH) to the ageing process is currently subject of considerably interest. The study was designed to investigate the effects of replacement therapy with growth hormone on quality of life, serum lipids and body composition (fat free mass and fat mass) in elderly men. MATERIAL 18 healthy men 60.0 +/- 2.4 (x +/- SEM) years of age. Their body weight was 78.6 +/- 4.6 kg and body mass index (BMI) was 26.5 +/- 1.4 kg/m2. Diagnosis of GH deficiency was based on serum insulin-like growth factor-1 (IGF-1) levels below 200 micrograms/L (138.1 +/- 9.2), abolished GH nocturnal surge and diminished glucagon-stimulated GH secretion compared to reference group of young men (16.2 +/- 1.8 to 30.6 +/- 4.7 micrograms/L/hour; p < 0.02 and 10.8 +/- 1.0 to 44.1 +/- 15.3 micrograms/L/hour; p < 0.02, respectively). Reference group comprised nine men 27.5 +/- 1.3 years of age with body weight 76.3 +/- 2.2 kg and BMI 23.1 +/- 0.6 kg/m2. The subjects received recombinant, human GH daily subcutaneously during 12 months in dose adjusted to maintain optimal (280-350 micrograms/L) serum IGF-1 level. The initial dose was 0.125 IU/kg b.w./week. Before, and after 6 and 12 months of therapy clinical and laboratory exams, including serum GH, IGF-1 and lipids levels, and body composition using two methods were obtained. Quality of life was assessed by modified Beck's questionnaire. 12-months replacement therapy with growth hormone in elderly men improved mental status, increased serum IGF-1 level to the young normal men values, from 138.1 +/- 9.2 to 279.4 +/- 26.3 micrograms/L, p < 0.001, reduced serum LDL-cholesterol from 3.67 +/- 0.12 to 3.10 +/- 0.21 mmol/L, p < 0.04 and increased serum HDL and HDL2 levels from 1.20 +/- 0.05 to 1.41 +/- 0.08 mmol/L, p < 0.002 and from 0.19 +/- 0.03 to 0.34 +/- 0.06 mmol/L, p < 0.005, respectively, reduced fat mass (12.8%, p < 003), particularly localised in trunk (14.7%, p < 0.03), and increased fat free mass (2.9%, p < 0.03). GH-replacement therapy in elderly men has beneficial effects on quality of life, and may counteract ageing and atherosclerosis progression by serum lipids and body composition improvement.

Abstract
OBJECTIVE Decline in growth hormone (GH) secretion and serum levels of insulin-like growth factor-1 (IGF-1) during ageing may be a causal factor in the development of osteopenia. The purpose of this study was to test the effects of GH-replacement therapy on bone metabolism and mineral density in healthy men over 40 years old. MATERIAL 18 healthy men aged 60.2 +/- 2.4 (avg +/- SEM) with mean body weight 78.6 +/- 4.6 kg and body mass index (BMI) 26.5 +/- 1.4 kg/m2. Diagnosis of growth hormone deficiency was based on serum IGF-1 levels below 200 micrograms/L (138.1 +/- 9.2), abolished GH nocturnal surge and diminished glucagon-stimulated GH secretion compared to reference group of young men (16.2 +/- 1.8 to 30.6 +/- 4.7 micrograms/L/hour; p < 0.02 and 10.8 +/- 1.0 to 44.1 +/- 15.3 micrograms/L/hour; p < 0.02 respectively). Nine healthy men aged 27.5 +/- 1.3 were recruited as a control subjects. Their body weight was 76.3 +/- 2.2 kg and BMI 21.3 +/- 0.6 kg/m2. METHODS The subjects received human, recombinant GH (rhGH) daily subcutaneously during 12 months in dose individually adjusted to maintain optimal (280-350 micrograms/L) serum IGF-1 level. Initial dose was 0.125 IU/kg b.w./week. Before and after 6 and 12 months of therapy clinical and laboratory exams, including serum GH, IGF-1, calcium, phosphate, osteocalcin, glucose, insulin levels and alkaline phosphatase (AP) activity were obtained. Lumbar spine and femoral neck bone mineral density (BMD) were measured by dual-energy X-ray absorptiometry. RESULTS rhGH administration for 12 months led to a significant increase in mean serum IGF-1 levels, from 138.1 +/- 9.2 to 279.4 +/- 26.3 micrograms/L (p < 0.001). Mean serum osteocalcin concentration rose from 19.4 +/- 1.7 to 34.4 +/- 4.7 micrograms/L (p < 0.004), and serum AP activity changed nearly significantly, from 78.0 +/- 4.8 to 88.1 +/- 7.2 U/L. Lumbar spine and femur neck BMD increased significantly after 12 months, from 1.092 +/- 0.05 to 1.119 +/- 0.06 g/cm2 (p < 0.05) and from 0.886 +/- 0.04 to 0.905 +/- 0.04 g/cm2 (p < 0.05), respectively. CONCLUSION Growth hormone replacement therapy in elderly men may be regarded as a method useful to protect against osteoporosis progression.

Abstract
The aim of this study was to determine the influence of testosterone replacement therapy in elderly men on mood, bone mineral density, and lipids. We investigated thirty men (mean +/- SD; age 61.1 +/- 5.6 yr) with testosterone concentrations (mean +/- SEM) 2.1 +/- 0.2 ng/ml. Testosterone deficiency was replacement by intramuscular injections of testosterone enanthate 200 mg every second week from 1.5 to 6 yr. (mean +/- SD; 3.35 +/- 1.6 yr.). During the treatment serum testosterone increased reaching normal levels (mean +/- SEM; 6.6 +/- 0.2 ng/ml). This was associated with significant increase in positive mood parameters and a decrease in negative mood parameters. Also self assessment of libido, potence and dream were improved. Bone mineral density (BMD) of lumbar spine increased. We noticed significant decrease in total cholesterol, and LDL-cholesterol. Hematocrit was increase Prostate-specific antigen concentration statistically increased from 0.65 +/- 0.1 to 1.35 +/- 0.1 ng/ml (mean +/- SEM), but in the cases of its levels were in normal range. Patients with coronary heart disease demonstrated decreasing ing symptoms of angina pectoris and nitrate requirement. In summary, long-term testosterone replacement therapy in elderly men may have beneficial effects on well-being, libido, potence, dream, bone mineral density, lipids, blood cell count and body mass (BMI). This therapy appears to be safe and there is no adverse effection on prostate.

Abstract
BACKGROUND Adrenocortical carcinoma is a rare tumor with a poor prognosis. This work was aimed at analyzing the clinical outlook and treatment results of 52 patients with this disease. METHODS This study included patients with adrenocortical carcinoma referred to the Department of Endocrinology at the Center of Postgraduate Medical Education (Warsaw, Poland) during the last 30 years. In 11 patients, the adrenal tumor was found incidentally by ultrasonographic scan. Hormonal examinations made it possible to define the endocrine activity of the tumors, whereas imaging techniques helped to determine their staging. Forty-eight patients underwent surgery, and 36 of them received mitotane. This drug was administered to 26 patients for a range of 10 months to 10 years; 13 patients received mitotane immediately after the operation, and 13 others after a delay. The patients with severe hypercorticism were pretreated before surgery with aminoglutethimide and mitotane. RESULTS The study comprised 10 men and 42 women; hormonally active tumors were diagnosed in 39 of them. Cushing's syndrome was the most frequent entity. At diagnosis, 17 cases were classified as localized disease, 15 as regional disease, and 20 as distant disease. Pretreatment with the inhibitors of steroidogenesis improved the survival perspectives in the early postoperative period. As of this writing, there were 12 survivors in the group of 26 patients treated by surgery and long term mitotane therapy and only 2 survivors of 7 patients treated with surgery only. CONCLUSIONS Surgery with immediate adjuvant long term mitotane administration was the most effective form of therapy for patients with adrenocortical carcinoma.

Abstract
OBJECTIVES The purpose of the study was to establish plasma levels of insulin, ovarian sex hormones and dehydroepiandrosterone sulfate (DHEA-S) and to evaluate their correlations with lipids in premenopausal women with angiographically demonstrated coronary stenosis. DESIGN Differences in plasma levels of insulin, ovarian sex hormones, DHEA-S and lipids between groups were compared by analysis of variance. SETTING From January 1993 until December 1993 patients were diagnosed in the Outpatient Clinic of the Department of Endocrinology Medical Centre for Postgraduate Education, Warsaw. SUBJECTS Premenopausal women with normal oral glucose tolerance test (OGTT) results, with and without coronary stenosis were studied: 21 women after acute myocardial infarction with angiographically demonstrated coronary stenosis (women with CHD), and 14 women with chest pain, a positive exercise test without significant changes of coronary arteries on coronarography (women with normal coronarography, NC). The control group consisted of nine, healthy women with no risk factors for CHD. MAIN OUTCOME MEASURES In premenopausal women with CHD, the decreased plasma level of DHEA-S and hyperinsulinaemia were anticipated. RESULTS In women with CHD, the plasma levels of DHEA-S (926.5 +/- 83 ng mL-1) were significantly lower than those in women with NC (1375.7 +/- 181 ng mL-1) and in healthy controls (1984 +/- 127 ng mL-1), P < 0.02 and P < 0.001, respectively. The fasting insulin and insulin response to an OGTT in women with CHD and with NC was higher than in healthy subjects. A significant decrease of high-density lipoprotein (HDL) cholesterol, HDL-2 cholesterol and apolipoprotein A-I, and an increase of total cholesterol, low-density lipoprotein cholesterol C and apolipoprotein B levels in women with CHD compared to healthy controls were observed. A negative correlation between fasting insulin and the plasma levels of DHEA-S was established. CONCLUSION In premenopausal women, hyperinsulinaemia and decreased DHEA-S levels may contribute to the development of coronary atherosclerosis.

Abstract
OBJECTIVES The purpose of the study was to evaluate the effect of transdermal 17 beta-oestradiol with oral progestogen on the plasma levels of lipids, lipoproteins and apolipoproteins in hypercholesterolaemic postmenopausal women. DESIGN During 6 months of replacement therapy with transdermal 17 beta-oestradiol combined with oral progestogen, plasma lipids, lipoproteins and apolipoproteins after 3 and 6 months were measured and compared with pretreatment values by Student's t-test. SETTING From January 1992 until September 1992 patients were diagnosed and treated in an out-patient clinic of the Department of Endocrinology Medical Centre for Postgraduate Education, Warsaw. SUBJECTS The patients studied were 11 non-obese postmenopausal women with hypercholesterolaemia based on the World Health Organization criteria. INTERVENTIONS Venous blood samples were obtained before and 3 and 6 months after the beginning of cyclic replacement therapy with transdermal 17 beta-oestradiol (E2 100 micrograms day-1 combined with oral chlormadinone acetate (2 mg day-1 for 7 days in each cycle). MAIN OUTCOME MEASURES The antiatherogenic effect of transdermal oestrogen replacement therapy exerted by increased levels of high-density lipoprotein subfraction 2 cholesterol (HDL2-C) leading to the decrease of the total cholesterol level was anticipated. RESULTS After 6 months of the treatment the concentrations of HDL2 cholesterol (HDL2-C) increased from 0.45 +/- 0.07 mmol l-1 to 0.73 +/- 0.03 mol l-1 (P < 0.05) but the levels of HDL3 cholesterol (HDL3-C) decreased from 1.15 +/- 0.06 mmol l-1 to 0.89 +/- 0.07 mmol l-1 (P < 0.05). The concentrations of total cholesterol decreased from 6.9 +/- 0.13 mmol l-1 to 6.2 +/- 0.2 mmol l-1 (P < 0.05). No changes were observed in the plasma levels of total triglycerides, HDL cholesterol, low-density lipoprotein (LDL) cholesterol, very-low-density lipoprotein (VLDL) cholesterol, VLDL triglycerides, apolipoproteins A-I and B. CONCLUSIONS In hypercholesterolaemic postmenopausal women, transdermally administered 17 beta-oestradiol 100 micrograms daily in combination with oral chlormadinone acetate has a beneficial effect through raising the level of the antiatherogenic HDL2-C subfraction and decreasing the level of total cholesterol.

Abstract
The effect of pirenzepine, a peripheric cholinergic antagonist, on GHRH-induced GH secretion was studied in 10 type I diabetic subjects and 8 healthy controls. GH response was significantly greater in diabetics than in the healthy controls (p < 0.02) with peak values of 59.6 and 15.9 ng/ml, respectively. Pirenzepine 20 mg in given 15 min before GHRH inhibited GH response in both groups. In diabetics GH response calculated as area under curve (AUC) was inhibited from 3666 to 260 ng/ml. min (p < 0.001) and in the controls from 831 to 255 ng/ml. min (p < 0.05). The great efficacy of pirenzepine in inhibiting GH hypersecretion in type I diabetes may find a clinical application in future.

Abstract
UNLABELLED Vasoactive intestinal polypeptide (VIP) is now considered to be a prolactin-releasing factor (PRF). The aim of this study was to determine the VIP concentration in peripheral blood in patients with prolactin-secreting adenoma compared to healthy subjects. We also examined the effect of bromocriptine administration on the plasma VIP concentration in patients with prolactinoma. Nine patients with prolactinoma (6 women and 3 men, aged 27-50) and 7 healthy control subjects (4 women and 3 men, aged 26-40) were examined. Blood samples for prolactin and VIP were collected at 06:00, 12:00, 18:00, 24:00. In prolactinoma blood was taken before and after bromocriptine administration. Serum prolactin concentration was determined by the radioimmunoassay. VIP concentration was measured by a specific radioimmunoassay Kit-INCSTAR Corp. (Minnesota, USA). Statistical significance was calculated using the analysis of variance. A single 5 mg oral dose of bromocriptine decreased the mean prolactin concentration during the first 24 hours of treatment. Plasma VIP concentration was higher in prolactinoma patients compared to healthy subjects. There was no change in plasma VIP level after bromocriptine administration. IN CONCLUSION in patients with prolactin secreting adenoma the plasma VIP concentration is increased.

Abstract
Neurotensin is a tridecapeptide, present in the central nervous system and the gastrointestinal tract in man and animals. The affect of orally administered ethanol (1 g/kg body weight) on the neurotensin secretion over 24 hr period was studied in eight young healthy men. No significant circadian rhythm of neurotensin secretion was detected in the eight subjects studied. Ethanol produced a progressive rise in the plasma level of neurotensin reaching a maximum at 12:00 (13.8 +/- 8.6 pmol/l). At 12:00 and 14:00, the neurotensin concentrations were significantly higher than on the placebo day (p < 0.05). The secretion rate of neurotensin was determined approximately using the area under the curve method. Ethanol produced a transient rise in neurotensin secretion over the first 12 hrs period (08:00-20:00 h) after its administration (p < 0.02). The observation that ethanol increases transiently the neurotensin secretion in man supports the hypothesis that neurotensin may be involved in the biological effect of ethanol. The source of its secretion remains to be elucidated.

Abstract
The aim of the study was the evaluation of growth hormone secretion under physiologic conditions in two groups of type I diabetics: responding and nonresponding to TRH stimulation. Both groups matched for age and metabolic control of diabetes were studied during 24-hours and after GHRH stimulation. The whole diabetic group (n = 18) showed circadian rhythm of GH secretion with mesor value of 4.03 micrograms/l. TRH-responders had lower mesor GH value than TRH-nonresponders: 3.53 vs. 5.32, p < 0.05. GH response to GHRH was almost identical in both groups. C-peptide level was lower in TRH-responders: 0.16 vs. 0.56 microgram/l, p < 0.05. No correlation was found between growth hormone response and HbA1 and C-peptide levels. It is concluded that type I diabetics responding to TRH stimulation are characterized by lower mean 24-hour GH levels and lower C-peptide values.

Abstract
UNLABELLED To determine the efficacy of the estrogen replacement therapy (ERT) on the bone mineral density (BMD) measured with quantitative computed tomography (QCT) in postmenopausal osteoporosis 16 women aged 46-72 were examined. They were divided into two groups: 8 women treated with conjugated estrogens (Group I) and 8 who did not received ERT (Group II). In all 16 patients the serum hormonal concentrations (LH, FSH and estradiol) were measured with radioimmunological methods. The bone densitometry was performed in all of them using the single-energy computed tomography (QCT) with the computer Picker 1200. Bone mineral density was measured in three lumbar vertebra (L1-L3) and expressed in milligrams K2HPO4 per ml. The bone mineral density (BMD) was statistically significantly higher in the estrogen treated group (Group I) in every vertebra compared with that of controls (Group II). The serum FSH concentration was statistically significantly lower in the ERT group (Group I) and a statistically significant correlation between FSH level and average BMD (Lmean) was present. IN CONCLUSION 1. the ERT is very efficacious in preventing bone loss in postmenopausal women; 2. measurement of BMD in lumbar vertebra L1 or L3 may be a sufficiently reliable and accurate, cost-effective and time-saving method of screening for osteoporosis; 3. the serum FSH determination seems to be useful in monitoring of the estrogen therapy for postmenopausal osteoporosis.

Abstract
In order to assess the efficacy and tolerability of new long acting bromocriptine: Parlodel MR (oral form) and Parlodel LAR (injectable form suitable for repeatable administration) 40 patients (29 women and 11 men) with pituitary tumours with hyperprolactinemia (PRL 70 micrograms/l) were investigated in a double blind study. Patients were divided into 2 groups of 20. In the first group Parlodel R or Parlodel MR in equivalent doses was given, the other group was administered Parlodel R or Parlodel LAR. During the next 6 months 20 patients were treated with Parlodel MR and the other 20 with Parlodel LAR. In all patients pituitary and peripheral hormones, CT scan and visual fields were examined before and after 28 days of bromocriptine treatment. During the next six months 20 patients were treated with Parlodel MR while the other 20 with Parlodel LAR. Serum PRL fell in all patients and values in the normal range were obtained in 36 patients. In 30 out of 35 patients with signs of pituitary tumour in CT scan, a significant tumour shrinkage was observed. Most patients achieved considerable clinical improvement: disappearance of galactorrhoea, resumed menses in women, increased potency in men. There were no difference in efficacy in Parlodel R, Parlodel MR and Parlodel LAR, but in the case of Parlodel LAR the least number of side effects was found. Treatment with long acting bromocriptine-Parlodel MR and LAR of patients with pituitary tumours with hyperprolactinemia is an efficacious, safe and better tolerated method than Parlodel R treatment.

Abstract
Thyrotropin-releasing hormone (TRH) blunts growth hormone (GH) response to various stimuli in normal subjects. We were interested if similar inhibitory effect of TRH could be demonstrated in diabetes mellitus where GH is abnormally regulated. In this study we compared the effect of TRH on GH response to L-dopa in normal and diabetic subjects. TRH 0.2 mg iv blunted GH response to L-dopa 0.5 g p.o. in normal subjects with peak GH values 13.1 and 7.3 micrograms/l, p < 0.05. In the diabetics no inhibitory effect of TRH was demonstrated and GH was even paradoxically increased after TRH: 14.9 and 21.9 micrograms/l, p = NS. Lack of inhibitory effect of TRH was more pronounced in patients with proliferative retinopathy. It is concluded that TRH has no inhibitory effect on L-dopa-induced GH response in diabetic subjects. This finding provides further evidence for disturbed GH regulation in diabetes mellitus.

Abstract
The aim of the study was to assess the relationship between the clinical classification of hyperthyroidism based on the 3-degree score system and T3 and T4 serum concentration. 161 patients with Graves disease or toxic goiter were studied. By comparing the number of scores separating the 3 subgroups in relation to the severity of disease with T3 and T4 serum concentration of tyreotoxic patients we found a very high statistically significant correlation. We also found the marked (by +50%) statistically significant increase in the serum T3 concentration related to the degree of hyperthyroidism severity.

Abstract
Majority of pituitary tumours secrete one of the named hormones: PRL, GH, ACTH, proopiomelanocortine, alpha and beta subunit of TSH, LH, and FSH. Some of those tumours secrete two or more hormones. The aim of this study was to determine the effect of bromocriptine (Parlodel MR and LAR) upon secretion of hormones and tumour size in 10 patients with mixed pituitary tumours. In all patients pituitary and peripheral hormones, CT scan and visual fields were examined before and after treatment with bromocriptine: Parlodel MR and LAR. Bromocriptine treatment decreased PRL secretion in all 10 patients; GH--in all 6 in whom it was increased; TSH--in 2, FSH--in 2 and alpha-subunit in all 6 in whom they were increased. In 5 patients treatment resulted in shrinkage of the tumour mass by 20 to 35%. In all examined subjects clinical improvement was achieved. Our results demonstrate that bromocriptine (Parlodel MR and LAR) is very effective and well tolerated in the treatment of patients with mixed pituitary tumours particularly those with hyperprolactinemia.

Abstract
There is no, so far, a rational method of therapy based upon the etiology of autoimmune Graves' ophthalmopathy. As a malignant Graves' ophthalmopathy we defined the most severe eye changes leading to the sight loss or permanent disability of vision which are classified as exceeded class 3c according to the eye changes classification of the American Thyroid Association [27]. The aim of the study was to develop the most efficacious method of therapy for malignant Graves' ophthalmopathy. The material consisted of 206 patients treated according to the 3-stage method: 1-st--corticotherapy, 2-nd--radiotherapy, including linear accelerator, 3-rd--orbital decompression. Moreover, in four patients plasmapheresis was applied and in additional five cyclosporine was administered. In all 206 patients the estimation of the results of the treatment was based on the Donaldson ophthalmopathy index [4]. It has been proved that corticotherapy combined with linear accelerator radiotherapy has been the most efficacious method of treatment. It has also the least number of side effects. Orbital decompression as the 3-rd stage of treatment was employed in those cases in which the previous two stages of medical therapy were unsuccessful.

Abstract
Atrial natriuretic hormone is involved in the control of blood pressure and water-electrolyte balance. In order to assess the relationship between atrial natriuretic hormone and hypertension in acromegaly, 34 subjects were studied, 18 with acromegaly (10 normotensive and 8 hypertensive) and 16 healthy controls. Plasma atrial natriuretic hormone levels, as well as plasma renin activity, aldosterone and growth hormone levels were measured in basal conditions in all subjects. Additionally, plasma renin activity and aldosterone levels were determined after standard stimulation. In hypertensive acromegalic patients, atrial natriuretic hormone plasma concentrations (39.8 +/- 3.5 ng/l) were significantly higher than in patients without hypertension (27.9 +/- 4.1 ng/l), and in controls (28.6 +/- 1.3 ng/l) (p less than 0.01 in both comparisons). Stimulated plasma renin activity values were decreased in hypertensive acromegalic patients when compared with those in normotensive patients (1.14 +/- 0.29 vs 4.03 +/- 0.66 micrograms.l-1.h-1, p less than 0.01). In acromegaly, atrial natriuretic hormone levels correlated with mean arterial pressure (r = 0.58, p = 0.01). These results suggest that atrial natriuretic hormone plasma levels are slightly increased in patients with acromegaly and hypertension.

Abstract
In order to establish the role of insulin in the pathogenesis of lipid abnormalities in hyperandrogenic women with the polycystic ovary syndrome (PCO) 49 women aged 18 to 35 yr with a normal glucose tolerance test were studied. They were divided into two groups: 27 women with PCO (9 obese and 18 nonobese), and 22 healthy women (12 with simple obesity and 10 with normal body weight). In the PCO group, the fasting insulin levels and the insulin response to oral glucose load were higher than in the matched controls. Significantly lower levels of HDL2-cholesterol and higher levels of apolipoprotein B were observed in obese and non nonobese PCO patients. In obese women with PCO this was associated with lower levels of HDL-cholesterol and apolipoprotein A-I (Apo A-I), whereas the levels of total triglycerides and VLDL-triglycerides (VLDL-TG) were increased. Multiple regression analysis in PCO women, after adjustment for age, body mass index and the levels of insulin and sex hormones, showed a strong positive correlation between the fasting insulin levels and total triglycerides and VLDL-TG, while a negative correlation was found between fasting insulin levels and apo A-I. These results indicate that hyperinsulinemia may play a role in the development of lipid disturbances in women with the PCO.

Abstract
Hydrodynamics of the eyes was investigated in 57 patients with exophthalmos, with various degree of infiltrative changes. Open angle glaucoma was not found in any case. In 12 eyes (10.5 p.c.) one observed a raised IOP (over 21 mm Hg)--checked by means, of an applanation tonometer with the patient looking straight on; in 24 eyes (18.4 p.c.) the IOP was near the upper limit of the normal pressure. Characteristic for glaucoma pathological changes of the optic disc and the visual field were absent in examined patients. All of them had the filtration angle open. The authors found a statistically significant dependency between the IOP and the degree of changes in the motor muscles, conjunctival tissue and in the lids. The authors suggest that the changes in the intraocular pressure have an external cause and stem from the disturbances of the venous circulation with exclusion of the primary hypertension.

The increase of the IOP--5 to 30 mm Hg--was observed in patients in whom severe infiltrative changes in the motor muscles dominated the clinical picture. Characteristic for glaucoma changes of the visual field and optic papilla were not seen, the angle was open and the outflow coefficient was in normal limits. The normalization of the IOP was obtained after decompensation of the orbits when the exophthalmos and the infiltrative changes in the motor muscles of the eye receded.

Abstract
The role of a high CRH level in normal pregnancy remains unknown. Therefore we evaluated the concentrations of CRH and the related hormones in patients with pregnancy-induced hypertension. Fourteen women with pregnancy-induced hypertension, aged 20-39, at 30-39 gestational week, were investigated. The control group consisted of 20 healthy pregnant women matched according to gestational age. Plasma CRH beta-endorphin-like immunoreactivity, cortisol, and human placental lactogen were measured by radioimmunoassay, ACTH by an immunoradiometric method. It was found that in hypertensive patients the mean CRH concentration was significantly higher (4257 +/- 840 (SEM) ng/l) than that in healthy pregnant women (1083 +/- 227 ng/l, p less than 0.001). The concentration of ACTH, however, was only slightly higher 65.0 +/- 6.0 vs 50.7 +/- 2.5 ng/l p less than 0.025, whereas the differences in beta-endorphin, cortisol and human placental lactogen were not significant. In both groups there was no correlation between the CRH level and those of the related hormones. In healthy pregnant women the CRH level closely correlated with gestational age (r = 0.76, p less than 0.001), whereas in patients with hypertension no such correlation was present (r = 0.29). We assume that the marked enhancement of plasma CRH in pregnancy-induced hypertension is probably caused by its decreased breakdown in ischemic placental tissue, but its increased synthesis in the placenta and its indirect counterregulatory hypotensive role must also be considered.

Abstract
UNLABELLED Arterial hypertension is common in acromegaly, but the pathogenesis of this complication remains unknown. To determine the role of an endogenous Na,K pump inhibitor/digoxin-like substance (DLS) in the pathogenesis of hypertension in acromegaly 76 subjects: 28 with acromegaly, 20 with essential hypertension and 28 healthy controls were studied. Serum DLS was measured with the use of radioimmunoassay and bioassay by the inhibition of digoxin-sensitive erythrocyte 86-Rb uptake. In acromegaly, the activity of DLS was significantly increased and plasma renin activity decreased in the hypertensive group, as compared with that of the normotensive group and controls. Moreover, DLS was elevated in the low-renin group of essential hypertension, as compared with that of the normal/high-renin group or controls. The activity of DLS correlated positively with mean arterial pressure and negatively with plasma renin activity, but not with growth hormone levels. IN CONCLUSION an endogenous sodium pump inhibitor/digoxin-like substance may play a role in the pathogenesis of low-renin hypertension in acromegaly.

Abstract
To determine the effect of hypercortisolaemia on the melatonin circadian secretion 12 patients with pituitary or adrenal dependent Cushing's syndrome and 5 healthy controls were studied. The melatonin circadian rhythm of secretion, observed in the control group, was abolished in the patients with hypercortisolaemia. Mean nocturnal melatonin levels and the integrated 24-hour secretion were significantly lower in the patients studied than those of the controls. Thus, in patients with Cushing's syndrome the melatonin levels are decreased and the circadian rhythm of this hormone is abolished.

Abstract
Plasma levels of dehydroepiandrosterone sulfate (DHEA-S), testosterone, dihydrotestosterone (DHT) androstenedione, sex hormone-binding globulin (SHBG), lipoproteins, apolipoproteins and high density lipoprotein (HDL) subfraction were measured in 32 men aged 26-40 years after myocardial infarction (MI) suffered at least 3-4 months prior to the study, who were normocholesterolemic and had angiographically demonstrated coronary occlusion. The control group consisted of 76 healthy men aged 25-40 years. Blood samples were obtained in the morning from fasting subjects. A significant decrease in plasma DHEA-S and DHT levels were found in MI patients. Also, a significant decrease in HDL-cholesterol, HDL2-cholesterol (HDL2-C) and apolipoprotein A-I, an increase in apolipoprotein B and LDL-cholesterol (LDL-C) levels were observed in those patients as compared with healthy men. However, there were no differences in testosterone, androstenedione and SHBG concentrations between the groups. Significant correlations between testosterone and HDL2-C (r = 0.46, P less than 0.01), as well as between DHEA-S and HDL3-C (r = 0.39, P less than 0.05) levels in MI patients were observed. These results suggest that decreased levels of plasma DHEA-S and DHT may promote the development of coronary atherosclerosis in men.

In order to determine a relationship of high blood pressure and plasma insulin levels in acromegaly and in obesity 59 subjects with normal glucose tolerance were studied. They were divided into three groups: (I) patients with acromegaly: 7 normotensives and 8 hypertensives, (II) 12 obese normotensives and 12 obese hypertensives and (III) 10 non-obese hypertensives, and 10 healthy subjects. Blood glucose and plasma insulin concentrations were measured in a fasting state and after an oral glucose load of 75 g. The fasting insulin concentrations in all the acromegalics and in all the obese patients were higher than those in healthy subjects. The insulin response to the glucose load was significantly enhanced in all the three groups of hypertensive patients compared with those of matched normotensive controls. The results indicate that insulin may play a role in the regulation of blood pressure in essential hypertension, and in such hyperinsulinaemic disorders as acromegaly and obesity.

Abstract
UNLABELLED In order to determine the influence of thyroid function on the pineal gland in humans, the circadian rhythm of the serum melatonin concentration was estimated in 16 women with thyroid disorders: 8 with hypothyroidism and 8 with hyperthyroidism, as well as in 5 healthy controls. A significant melatonin circadian rhythm was observed in all the three groups studied. The melatonin rhythm parameters derived from cosinor analysis: mesor (controls: 0.163 +/- 0.03 nmol/l (+/- SEM), hypothyroid patients: 0.176 +/- 0.22 nmol/l, and hyperthyroid patients: 0.167 +/- 0.04 nmol), amplitude (0.155, 0.145 and 0.138 nmol/l, respectively), acrophase (1:38, 2:22 and 1:51 h, respectively) did not differ significantly in the three groups studied. Integrated 24-h melatonin secretion was also similar in patients and controls. The melatonin concentrations were positively correlated with TSH levels in hypothyroidism, and negatively correlated with T3 in hyperthyroidism. IN CONCLUSION in patients with hypo- and hyperthyroidism the circadian rhythm of melatonin secretion is not altered.

Abstract
In order to estimate the neuroendocrine function of the central nervous system eventually leading to growth hormone (GH) secretion in essential hypertension, 17 patients with mild arterial hypertension (7 obese and 10 with normal body weight) were examined. The control group consisted of 16 normotensive volunteers (7 obese and 9 with normal body weight). The GH secretion was determined by radioimmunoassay during nocturnal sleep. In all the subjects, the serum GH was also measured after placebo and after the centrally acting alpha 2-adrenergic agonist-clonidine administered i.v. in a dose of 0.15 mg. The fasting serum insulin concentration was also measured in all the subjects. Clonidine decreased the mean arterial pressure in all the subjects investigated. However, in response to clonidine an increase in GH secretion in all hypertensive and normotensive cases with normal body weight was demonstrated, whereas in all obese hypertensive and normotensive patients no significant GH rise was found. It indicates that inhibition of GH secretion in patients with essential hypertension is related to coexistent obesity rather than with that of arterial hypertension. A strong (r = 0.76) and significant (p less than 0.0005) correlation demonstrated between the maximal GH concentration during the nocturnal sleep and after clonidine suggests that the mechanism of GH inhibition in response to both these stimuli is similar and it probably is related to the inhibition of neurohormonal secretion of the growth hormone releasing factor (GRF). However, the negative correlation between the fasting insulin concentration and GH response to clonidine shown in obese subjects only, points to a more complex mechanism of GH inhibition in obesity.

Abstract
A 21-year-old woman suffering from acromegaly was treated with transsphenoidal subtotal hypophysectomy (microscopy: acidophilic adenoma), followed by x-ray and bromocriptine therapy. Seven years later she was re-operated because of a partial bitemporal loss of vision, intracranial hypertension, and regrowth of the pituitary tumour seen on CT-scan. A large part of the invasive suprasellar tumour was then removed by transcranial approach. The neurosurgery was followed by cobalt radiotherapy and bromocriptine administration. Two years later, symptoms and signs of tumour growth reappeared. Administration of cytostatics, such as doxorubicin (Adriamycin) and lomustine (Belustine), resulted in distinct clinical improvement associated with a seven-fold decrease in the serum growth hormone concentration. The visual field became normal and the intracranial mass on a CT scan decreased markedly. As a result the patient was able to resume work.

Abstract
In order to elucidate the role of the dopaminergic system in the control of aldosterone secretion in acromegaly with arterial hypertension 10 patients and 10 healthy volunteers were studied. Plasma aldosterone and prolactin were determined by radioimmunological methods after dopaminergic receptor blockade with metoclopramide and sulpiride. Plasma aldosterone was also determined after adrenal stimulation with synthetic corticotrophin (Synacthen). In patients with acromegaly and hypertension, the aldosterone secretion in response to metoclopramide was completely inhibited whereas induced with corticotrophin was lower than in controls. Also prolactin secretion in response to metoclopramide or sulpiride was markedly lower as compared with that in controls. Sulpiride did not stimulate aldosterone secretion either in patients or in healthy controls. The results indicate that the dopaminergic control of aldosterone secretion in acromegaly with arterial hypertension is altered.

Abstract
Growth hormone (GH) response was studied in 8 insulin-dependent and 7 non-insulin-dependent diabetics after stimulation with L-Dopa (500 mg orally) and TRH (0.2 mg iv.). L-Dopa induced a clear GH response in insulin-dependent diabetes (IDDM) and in the control group while in non-insulin-dependent diabetes (NIDDM) peak GH levels were lower (P less than 0.05) and 4 of 7 subjects failed to respond to L-Dopa stimulation. TRH had no effect on GH levels in NIDDM and in the controls. Insulin-dependent diabetics responded to TRH stimulation and GH levels at 20 and 30 min were significantly higher as compared with NIDDM and the control group. The degree of hyperglycemia seemed not to influence GH response. The highest GH levels were noted in two patients with proliferative retinopathy. It is suggested that TRH-induced GH release may be a characteristic feature in some patients with IDDM.

Abstract
The aim of this study was to evaluate the effect of the agonistic LRH analogue (D-Trp6-LRH) on LH, FSH and prolactin secretion, and its possible efficacy in female patients with anorexia nervosa. The study included 18 female patients with anorexia nervosa and 7 healthy women in the same age group. The patients with anorexia nervosa were divided into two groups of 9 women each. The first group consisted of patients in the weight loss phase of the disorder and the second of 9 women who had achieved normal body weight. Additionally, in 6 women with anorexia nervosa serum LH concentration was determined in response to native LRH before and 14 days after the treatment with D-Trp6-LRH. Serum LH, FSH, prolactin concentrations were determined before and 5, 10, 24 and 48 h after administration of D-Trp6-LRH in a dose of 5 micrograms. The serum LH response to D-Trp6-LRH in the second group did not differ from that of the control group. However, in women with anorexia nervosa in the weight loss phase, LH release in response to administration of the analogue was significantly lower. FSH release after LRH analogue administration in both groups of patients with anorexia nervosa did not differ from that in the control group. The increased LH secretion in response to native LRH after treatment indicates that D-Trp6-LRH in low doses did not inhibit pituitary responsiveness. A dose of 5 micrograms of D-Trp6-LRH was administered in a therapeutic regimen every 48 h from 1 to 3 months to 7 of 9 patients with anorexia nervosa who exhibited amenorrhoea in spite of normalization of body weight.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The aim of this study was to develop a technique for the radioimmunological determination of the activity of LH-like substances in the human prostate. The material comprised 19 specimens of prostatic tissue obtained during transbladder extirpation in patients with benign prostatic hyperplasia. Tissues of human testes and human sceletal muscle were used as controls. The method adopted for LH extraction from the membrane fraction of human prostatic tissue appeared to be sufficiently specific, accurate and sensitive for routine laboratory investigations. The concentrations of the LH-like immunoreactivity in human testicular tissue was found to be 57, 46 and 70 mU per g of the membrane fraction while those of the prostatic gland tissues ranged from 34 to 155 mU per g of the membrane fraction. However such LH-like substance was not found in human sceletal muscle tissue. It seems that the LH-type activity is an indirect proof for the existence of LH receptors in the human prostate.
