A course of the disease of a 68-year-old female who had been taking medigoxin, furosemide, verapamil and an unknown amount of spironolactone and potassium salt due to congestive heart failure is presented. She was admitted to emergency department of the University Hospital Rebro after an episode of syncopal attack because of arrhythmia due to hyperkalemia (8.9 nmol/L). She has had a fast idioventricular rhythm, followed by atrial tachycardia after that and with fast ventricular rhythm, S-T segment depression and a tall and peaked T-wave. In the following electrocardiograms left anterior hemiblock appeared, a tall R-wave of the anterolateral location, supraventricular and ventricular premature beats and atrioventricular block of the first degree. The patient had signs of non-oliguric form of acute renal failure at the admission which was a partly explanation for the development of hyperkalemia, together with the use of spironolactone and potassium salt. After the treatment she had normal serum creatinine values. She suffered from combined mitral valve disease: stenosis with a predominant regurgitation of the II/III degree. She was discharged from the hospital in a compensated state with normal serum potassium values.

We addressed the hypothesis that platelets are not activated in association with effort-induced myocardial ischemia in stable coronary disease. Seventy-two patients undergoing a diagnostic bicycle exercise test were stratified according to the development of chest pain (yes/no, 33/39) and of exercise-induced ST-segment depression of at least 200 microV in the electrocardiogram (yes/no, 12/60). Noninvasive indexes of platelet activation and of platelet/vessel wall interaction (urinary excretion of the 2,3-dinor-metabolites of thromboxane A2 [Tx-M] and prostacyclin [PGI-M], respectively) were analyzed in samples collected in the basal state and after the test. Basal Tx-M and PGI-M did not differ in patients with (236 +/- 35 and 131 +/- 22 pg/mg creatinine, respectively) and without (185 +/- 16 and 101 +/- 13 pg/mg creatinine, respectively) chest pain, or in those with (178 +/- 45 and 162 +/- 41 pg/mg, respectively) and without (216 +/- 22 and 104 +/- 11 pg/mg, respectively) ST-segment depression during the test. Patients without chest pain or without ST-segment depression moderately increased (p less than 0.05) their urinary Tx-M (by 21% and 13%, respectively) and PGI-M (by 28% and 23%, respectively) after exercise. No significant increases were observed in those developing chest pain or ST depression during exercise. These data indicate that effort-induced myocardial ischemia is not associated with an increase in platelet activation or platelet/vessel wall interaction in patients with stable coronary disease.

Twenty-four women with large, myomatous uteri, measuring between 218.7 and 2,920 cm3 were treated with gestrinone, a tri-enic steroid with antiestrogen and antiprogesterone properties. In order to saturate the receptors of the large myomata, the doses used to treat these women were twice the recommended dosage of 2.5 mg, 3 times weekly, used to treat smaller tumors. The treatment lasted 6 months to 1 year. In all cases there was a reduction in uterine volume. In the 24 patients, the mean uterine volume of 724.9 cm3 on admission decreased to 450.73 cm3 at 6 months. For 14 patients treated for a full year, the mean uterine volume of 689.73 cm3 decreased to 329.22 cm3. Menstruation was suppressed in all patients by the end of the 2nd month of treatment. Episodic bleeding occurred in 6 patients but in only 1 did this last longer than 1 week. Other symptoms such as pelvic discomfort and dysuria disappeared or were significantly alleviated by the 2nd month of treatment. Side effects included seborrhea, acne, nervousness, myalgia and arthraglia, hoarseness and mild hirsutism but all these symptoms were promptly reversed following discontinuation. The mean increase in weight was 3.4 kg in 6 months. No menopausal symptoms such as hot flushes and depression developed during this trial. Six patients complained of excessive sweating. Blood glucose creatinine, blood urea nitrogen, alkaline phosphatase, pyruvic and glutamic transaminases remained within the normal range.

The causes, extent, and quantification of depression in end-stage renal disease (ESRD) patients have been a concern of psychologists and physicians. To assess depression and its possible causes, 57 patients with ESRD treated with hemodialysis (HD, n = 43) or continuous ambulatory peritoneal dialysis (CAPD, n = 14) and 16 patients with chronic renal insufficiency (CRI) were interviewed and completed the Beck Depression Inventory (BDI) and the Illness Effects Questionnaire (IEQ). An ESRD severity coefficient was used to measure chronic illness severity in the patients treated with dialysis, and blood urea nitrogen (BUN) and creatinine levels were used to assess severity of renal disease and adequacy of treatment. A cognitive item subset of the BDI (CDI) was used as a measure of depression. When patients treated with HD and CAPD were compared, CAPD patients were younger, had a shorter duration of dialysis treatment, and less severe medical illness, but the groups did not differ on the IEQ, BDI, or CDI. The IEQ did not correlate with age or disease variables. Both the CDI and the total BDI scores correlated with the IEQ. Perception of illness (IEQ) correlated significantly with cognitive depression for the CAPD and HD patients. For CAPD patients only, a significant correlation between the IEQ and severity of medical illness was obtained. Perception of illness and creatinine concentration were strongly correlated with cognitive depression in the patients with CRI as well. For all renal patients, level of depression was more strongly related to perception of illness than physical illness variables.(ABSTRACT TRUNCATED AT 250 WORDS)

Grey seal pups (Halichoerus grypus) were collected at the time of weaning (mid-October) and fasted for 52 days at thermoneutrality in separate cages. Body weight decreased exponentially, while metabolic rate dropped 45% from an average of 2.95 +/- 0.15 (SEM) W kg-1 at day 2 of fasting to a stable level of 1.62 +/- 0.06 (SEM) W kg-1 from day 10 to day 47 of fasting. Respiratory quotient was low, indicating extensive catabolism of triglycerides, while plasma cortisol was fairly stable at 110 +/- 8 (SEM) nmol l-1 throughout the fasting period. Daily urinary output decreased from 236 +/- 20 (SEM) ml day-1 at day 2 to a stable value of 87 +/- 6 (SEM) ml day-1 between days 8 and 50 of fasting. The urine was analysed for urea, uric acid, creatinine, ammonia, total nitrogen and osmolality. Urea was always the principal excretory end-product, amounting to between 70 and 80% of the total excreted nitrogen. The urine was moderately concentrated (range 770-1300 mosmol kg-1). Total excreted urinary nitrogen decreased by 68% from 3.7 +/- 0.7 (SEM) g day-1 to 1.2 +/- 0.4 (SEM) g day-1 between days 2 and 50. The urinary nitrogen was used to calculate the daily amount of protein being oxidized and its energy content was compared with the measured basal metabolic rate of individual animals. Approximately 6% of the energy expended by grey seal pups during the post-weaning fast is derived from oxidation of protein. It is concluded that a rapid depression of basal metabolic rate and extensive blubber catabolism enable grey seal pups to endure prolonged periods of fasting without any apparent signs of discomfort or stress.

A 5-year-old mixed breed dog was presented with a history of depression and anorexia. Physical examination revealed a pharyngeal tumour and a neurological examination indicated the presence of a possible space-occupying lesion in the brain. Investigative procedures included a bloodsmear, impression smears and cytology of the pharyngeal tumour, haematology, chemical pathology, faecal analysis, urinalysis, electrocardiography, cerebrospinal fluid analysis, hormone assays and a computerised axial tomography scan. Results of these investigations revealed a round cell tumour in the pharynx, hypergammaglobulinaemia (34 g l-1), azotaemia (urea 8.6 mmol l-1 and creatinine 170 mumol l-1), hypoalbuminaemia (20 g l-1), proteinuria, sinus bradycardia (heart rate 60 beats per min), increased concentration of protein in the CSF (1.1 g l-1), hypoadrenocorticism (base line cortisol less than 55 nmol l-1) and hypothyroidism (T4 less than 13 nmol l-1). The computerised axial tomography scan revealed a brain tumour in the region of the hypophysis. The dog was euthanased and a post mortem examination confirmed the presence of a pharyngeal tumour with apparent direct extension of the tumour into the brain. Both tumours were confirmed histologically as mastocytomas.

The harmful effect of iron excess was studied in an experiment using fifteen adult sheep. The animals were divided into three groups of 5 each. The sheep of the group I were kept as controls, those of the group II and III were supplemented with iron in doses of 80 and 40 mg/kg body weight (BW)/24 h respectively. The animals of group II died after a period of 3-7 weeks showing anorexia, loss of weight, diarrhoea, depression and symptoms of circulatory and respiratory failure. From the animals of group III one died after 13 weeks, with symptoms of pulmonary oedema, while the other 4 survived for 22 weeks, together with the animals of the control group. The iron-supplemented animals presented increased values of Serum Iron (SI), Total Iron Binding Capacity (TIBC), percent Transferring Saturation (% SAT), Alanino aminotransferase (ALT), serum Alkalin Phosphatase (SAP), Serum Urea Nitrogen (SUN) Creatinine, Phosphorus and decreased values of serum Copper concentration. These parameters were greater in group II. The iron concentration in the liver, spleen, myocardium and kidneys was also much higher than in the controls. The histological examination revealed degeneration of the liver, spleen, myocardium and kidneys in both groups, while cells overloaded with hemosiderin were seen in the third group only. In conclusion, it was shown that chronic intoxication may occur in sheep overdosed with iron. The toxic dose of iron ranged between 40 and 80 (mg/Kg body weight) per day and was close to 40 mg, when iron was administered in the soluble from FeCl3.6H2O.

MK-0521 and captopril were orally administered to acute (6 to 8 days after unilateral renal artery constriction) and chronic (2 to 2.5 months after the constriction) 2-kidney Goldblatt hypertensive dogs for 7 to 21 days. MK-0521 lowered the blood pressure to similar extents in the acute and chronic stages of hypertension. The antihypertensive effect of MK-0521 was dose-dependent and persistent even after its cessation. Captopril also produced an antihypertensive effect, although the effect in the chronic stage of hypertension was less prominent than that in the acute stage of hypertension. MK-0521 was more inhibitory on the renin-angiotensin system than captopril. In the acute stage of hypertension, the dogs treated with MK-0521 had increased angiotensin converting enzyme (ACE) activity, while they had decreased plasma angiotensin II level and elevated plasma angiotensin I level and plasma renin activity. These results clarified the inhibitory effect of MK-0521 on ACE. In contrast, in the chronic stage of hypertension, MK-0521 showed no depression of plasma angiotensin II. There were no significant changes in daily urinary volume, and renal clearances of sodium, potassium and creatinine. These results suggest that the major mechanism of the antihypertensive effect of MK-0521 in 2-kidney Goldblatt hypertensive dogs is an inhibition of the ACE. In addition, the different effects in the acute and chronic hypertensive dogs suggest that some differences exist in the mechanisms of maintaining blood pressure between the two stages of 2-kidney Goldblatt hypertensive dogs.

Factors influencing the depression of natural killer (NK) activity and its prevention were studied in 57 esophageal cancer patients. NK activity off peripheral blood mononuclear cells was measured by a 51Cr-release assay against K-562 target cells. NK activity in esophageal cancer patients was significantly lower than that in healthy individuals and tended to be lower compared with those in stomach and colon cancer patients. The depression of NK activity was significantly correlated with the reduction of serum albumin level, creatinine height index of nutritional assessment. The activity was also suppressed in proportion to the size of cancer and its staging. Both preoperative radiation and surgery markedly depressed NK activity. Postoperative depression recovered to the Preoperative level 4 weeks after operation. These results indicated that malnutrition, cancer bearing and therapeutic stress were associated with the depression of NK activity. As the preventive measures against such depression of NK activity, avoidance of preoperative radiation and better selection for two-stage operation enhanced recovery of the depressed NK activity. Furthermore, the preoperative administration of OK-432, as n immuno-activator, could be effective to minimize a decrease of NK activity related to radiation and surgery, and to accelerate its recovery to the level before treatment.

Urinary free cortisol (UFC) excretion in 31 patients with major depression is directly compared to UFC levels in 65 patients with panic disorder and 36 controls. Patients with depression demonstrated significantly higher UFC excretion [43 +/- 37 micrograms/g creatinine (cr)] than patients with panic disorder (29 +/- 13 micrograms/g-cr) or controls (22 +/- 10 micrograms/g-cr) (F = 8.5, df = 129, p less than 0.001). Panic patients with a secondary depression (35 +/- 17 micrograms/g-cr) or those with agoraphobia (34 +/- 14 micrograms/g-cr) had UFC levels that were in-between patients with primary major depression and panic patients without these complications (25 +/- 11 micrograms/g-cr). These findings support the hypothesis that patients with major depression, whether primary or secondary, and those with agoraphobia excrete more UFC than patients with uncomplicated panic disorder. This occurs despite the fact that panic disorder might also be expected to raise the stress-responsive hormone cortisol.
