Hypoglycaemia (blood glucose 1.3-2.5 mmol/l) was induced in thirty diabetic children by reduction of their morning meal. Glucagon, 10 or 20 micrograms/kg was then given by intramuscular or subcutaneous injection. Ten min later, all signs of hypoglycaemia had disappeared and blood glucose concentrations increased by 0.7-3.3 mmol/l. Glucagon plasma concentrations at glucose nadir were low, 23 +/- 8 pmol/l, rose to 300 +/- 42 ten min after the injection and reached peak values after another ten min. Later, a slow decrease was noted. No significant difference of blood glucose or plasma glucagon concentrations were found after subcutaneous or intramuscular injections of 20 micrograms/kg. After 10 micrograms/kg, slightly lower increase of blood glucose was seen, but the clinical effect was equally good. Nausea occurred in four children given 20 micrograms/kg. The rise of blood glucose did not correlate to the peak glucagon concentration obtained after the injection but showed significant correlations to the lowest glucose concentration and, inversely, to the concentration of free insulin in blood at glucose nadir. It is concluded that glucagon injections are effective in hypoglycaemia in insulin-treated diabetic children and that the injection of 10-20 micrograms/kg gives long-standing supraphysiological concentrations which make repeated injections unnecessary.

This study compared the effects of ingesting 6% (MC) and 12% (HC) glucose/electrolyte beverages, and a flavored water placebo (P) on markers of fluid absorption, palatability, and physiological function during prolonged intermittent cycling in the heat. On three occasions, 15 trained male cyclists performed two 60 min cycling bouts at 65% VO2max (E1 and E2). A brief exhaustive performance ride (approximately 3 min) was completed after E1 and E2, and after 20 min recovery (P1, P2, P3). Every 20 min, subjects consumed 275 mL of P, MC or HC. The first drink contained 20 mL of D2O, a tracer of fluid entry into blood plasma. Plasma D2O accumulation was slower for HC than for P and MC (P less than 0.001). HC caused more nausea (P less than 0.01) and fullness (P less than 0.05) than MC or P, and subjects said they would be less likely to consume HC during training or competition (P less than 0.10). Sweat rates, HR, Tre, Tsk, VO2, and PV were similar for all drinks. Performance of P1, P2, P3 were not different among drinks. However, four cyclists failed to maintain the prescribed work rate during E2 for HC but only one failed for MC and P. These data suggest that the slow absorption of a 12% glucose/electrolyte beverage during prolonged intermittent exercise in the heat may increase the risk of gastrointestinal distress and thereby limit performance.

Eating related difficulties and symptoms and postprandial serum glucose levels were studied in 11 patients (44 to 70 years old) five to 48 months after total gastrectomy and Roux-en-Y reconstruction for carcinoma of the stomach with no signs of metastasis or residual tumor. Three tests were used. The first contained 150 milliliters of 50 per cent glucose alone, the second had 150 milliliters of 50 per cent glucose with 5 grams of guar gum (viscose dietary fiber) and the third was a vegetable meal containing 75 grams of glucose. All of the patients with total gastrectomy had eating related symptoms, such as dumping and difficulties with the large volume of a meal. They had to eat small meals and the most usually experienced postprandial symptoms were abdominal pain, nausea and faintness. The postprandial serum glucose level was highest after drinking glucose alone and the lowest after eating the vegetable meal (as the highest 9.4 +/- 2.0 and 6.2 +/- 1.6 millimole per liter, respectively, 50 minutes postprandially, p less than 0.01). Hyperglycemia was associated with nausea, sweating, faintness, reduction of blood pressure and increase of pulse rate. The large volume of the vegetable meal produced difficulties (dysphagia and abdominal distension) in eating for everyone except one patient. Guar gum eaten with glucose reduced the postprandial hyperglycemia near to the level found after the vegetable meal. Also, the symptoms experienced after glucose with guar gum reduced from that after glucose alone, five patients became symptomless. Four of these five patients have supplemented guar gum regularly for several months into their daily meals with the result of reduction of the postprandial subjective symptoms. The dose has been adjusted individually from 2 to 7 grams of guar gum three times daily. Loose stools and diarrhea may occur at the beginning. These are avoided by a gradual increase of the dose during an adaptation period of two weeks. Sometimes glucose with guar gum may result in hypoglycemia with prolonged symptoms after immediate hyperglycemia. It is concluded that guar gum gives a possibility to avoid the symptoms related to a large volume of a meal and to reduce those produced by a high glucose content of a meal in patients after total gastrectomy. Guar gum also works in practical prolonged use when the dose is estimated from postprandial symptoms.

Problems related to general anaesthesia of 109 consecutive vitrectomies performed on diabetic patients were retrospectively reviewed. On the morning of surgery a normal or a slightly reduced dose of the patient's regular insulin was administered subcutaneously. The amount of intravenous infusion, mostly 5% glucose, was calculated according to the pre-operative urine volume. After surgery, hypoglycaemic (less than 3 mmol/l) values were seen in less than 11% of the patients, and high glucose in less than 30%; 20% had a mild ketoacidosis post-operatively. Difficulties in tracheal incubation was encountered in 10%. Three patients complained of chest pain after surgery, and in one of them a myocardial infarction was diagnosed. Forty-one per cent of the patients complained of nausea or vomited in the afternoon after surgery, and 21% had difficulties in urination the night after surgery. Two of four patients with peritoneal dialysis complained of stomach pain post-operatively. There was no significant association between recurrent vitreous haemorrhage and blood glucose concentration or arterial blood pressure in the early post-operative period.

A 29-year-old nullipara was admitted at 31 weeks' gestation because of toxemia. She noted gradually polyuria, severe thirst, malaise, nausea and anorexia. A water-deprivation test and administration of aqueous vasopressin confirmed the diagnosis of nephrogenic diabetes insipidus. At 33 weeks' gestation, blood chemistry studies revealed moderately elevated transaminase levels and hyperuricemia. Male twins were delivered by vacuum extraction at 35 weeks' gestation. After delivery, she became drousy and icterus appeared. Acute hepatic failure with marked hyperuricemia was diagnosed. She was treated with glucose solution with glucagon and soluble insulin, branched chain amino acids, gabexate mesilate, lactulose and famotidine. Her consciousness cleared rapidly and all laboratory data became normal by 15 days postpartum. The urine volume was about 5 liters per day from the first to sixth postpartum day. The diuresis decreased after the eighth postpartum day. Rare pregnancy complicated by transient nephrogenic diabetes insipidus and acute hepatic failure is discussed.

Exposure to 1,3-dinitrobenzene (1,3-DNB) in humans induces methaemoglobinaemia, nausea and nervous symptoms. When given to conventional rats, twice-daily oral doses of 10 mg kg-1 1,3-DNB produce methaemoglobinaemia and frequently ataxia after four or five doses. In germ free rats given only a single oral dose of 20 mg kg-1, similar symptoms occur but are of more rapid onset. Light and electron microscope examinations reveal an acute thiamine deficiency-like lesion in the brain stems of both ataxic and apparently normal rats. Bilaterally symmetrical vacuolated lesions involve cerebellar roof, vestibular and superior olivary nuclei and the inferior colliculi. Frequent petechial haemorrhages are associated with these lesions, the erythrocytes usually being limited to enlarged Virchow-Robin spaces but sometimes spreading more widely. The primary cellular targets appear to be astrocytes, oligodendrocytes and vascular elements with secondary neuronal involvement. It is suggested that 1,3-DNB interferes with intracellular redox mechanisms resulting in impaired glucose oxidation.

The effect of a new dopamine agonist, CU 32-085 (8 alpha-amino-ergoline), on pituitary function in acromegaly was evaluated by a controlled, single blind study of 12 acromegalics. The study included a single dose placebo/drug (0.5 mg CU 32-085) trial and a long-term crossover trial with 3 month periods (placebo/CU 32-085 8 mg daily). The patients were evaluated clinically and biochemically (oral glucose tolerance (OGTT), TRH- and LHRH-tests) before and after each 3 month period. Nine patients completed this long-term trial; one died from myocardial infarction during the placebo period, and two dropped out because of side effects. The release of GH, judged from more than 9 h suppression of serum GH following the single dose, and from the response to OGTT after the long-term treatment, was significantly inhibited by CU 32-085. Serum GH reached normal values in 4 of 9 patients. Serum PRL was also markedly suppressed, to subnormal values after the 3 months in all but one hyperprolactinemic patient. Serum TSH, cortisol, FSH and LH were generally unaffected. Glucose tolerance was not significantly altered, although an improvement was found in six of nine patients. A semiquantitative evaluation of subjective symptoms showed a significant improvement following the long-term treatment, while objective signs of acromegaly were unaffected. The blood pressure was slightly lowered, both after a single dose and after 3 months' treatment. Seven patients experienced nausea and dizziness, two of them with vomiting, after a single dose of the drug. Four of these had similar symptoms initially during the long-term treatment, which forced two to interrupt the trial. We conclude that CU 32-085 caused a marked suppression of the release of GH and PRL and an improvement of the major symptoms of acromegaly, a therapeutic effect that is comparable to the previous experience with bromocriptine.

This study evaluated the effect of gastric bypass on the glucose, insulin, vasoactive intestinal peptide (VIP), neurotensin, and motilin response to orally administered glucose in eight morbidly obese patients before and after operation. Preoperatively, all eight patients remained asymptomatic during an oral glucose tolerance test, which showed glucose intolerance and hyperinsulinism. Plasma VIP, neurotensin, and motilin remained below detectable levels for the entire test. At three months following gastric bypass (21% weight loss), all eight patients became acutely ill during a repeated oral glucose tolerance test and had the following symptoms: facial flushing (eight patients), palpitations (eight patients), nausea (seven patients), abdominal fullness (seven patients), pallor (four patients), diaphoresis (two patients), vomiting (two patients), and diarrhea (two patients). Significant release of neurotensin occurred in seven patients while three patients had release of VIP, further implicating these two peptides as part of the pathophysiologic spectrum of the "dumping syndrome."

Femigen forte (chlormadinone 3 mg + mestranol .1 mg) was administered to 90 women and Femigen mite (chlormadinone 2 mg + .084 mg of mestranol) was administered to 43 women, both groups aged 19-47 years, as a contraceptive and as therapy for endometriosis, dysmenorrhea, irregular and profuse menstruations, in the incipient phase of climax, and in diagnostics. Both drugs were observed to be 100% effective as contraceptives. Side effects such as nausea, intermenstrual bleedings, and absence of menstruation were most often observed with Femigen forte; about 30% of these users. Most side effects occurred in the first 2 cycles. Those using Femigen mite showed almost no side effects. No increase in the concentration of blood glucose was noted with either preparation. The effect of these drugs on the vaginal lining and on the endometrium was weak. No thromboembolic complications were observed. The low-dose preparation was recommended more for contraception. An estrogenic content of about .05 mg creates the same effect and decreases the occurrence of side effects.

The use of intraamniotic injection of hypertonic solutions for termination of pregnancy during the second trimester has been generally adopted. Because of side effects in such treatment with other agents, it was decided to use intraamniotic instillation of urea solution (Urevert) to induce midtrimester therapeutic abortion in 38 patients. The method was successful in 35 patients (92%) with a mean injection/abortion interval of 26.1 hours, shorter than that with the use of hypertonic saline or hypertonic glucose solutions. The side effects of headache, nausea, and vomiting were mild, and an endometritis in 1 patient responded well to antibiotic treatment. Intravenous oxytocin drip was necessary in patients with hypotonic contractions or in those who failed to react within 36 hours after injection. In 3 cases of missed labor, the urea solution injected induced labor within 5-8 hours, with no side effects. The mean in-patient hospital time was 4.3 days.
