ABSTRACTTwo cases of intravenous injection of elemental mercury are described in this report. One patient succumbed and the other remains asymptomatic two years after the surgical removal of all the injected mercury. Management of intravenous injection of elemental mercury (intended to be an aphrodisiac in these two cases) is discussed here and the need for surgical removal of all accessible mercury has been emphasized

Nasogastric Tube Feeding

Postoperative swallowing problems were investigated in 20 patients who had undergone various degrees of surgical resection for oral cancer. The swallowing problems were evaluated on the basis of type of food, degree of aspiration, and duration of postoperative nasogastric tube feeding. Two patients with tongue cancer who had had hemiglossectomy without reconstruction ate normal food without aspiration within a week after operation. Eight patients who had undergone two- to three-quarter glossectomy for tongue cancer ate gruel with no or occasional liquid aspiration. Among 4 patients who had had near-total or total glossectomy for tongue cancer, 3 ate thin gruel or liquid with occasional aspiration. The other could not eat orally because of consistent severe aspiration. One patient with mouth floor cancer underwent resection of the mouth floor in combination with hemiglossectomy and she ate gruel without aspiration. Among 5 patients with mouth floor cancer who had had surgical removal accompanied by near-total or total glossectomy, 3 ate gruel with no or occasional liquid aspiration, 1 ate thin gruel with no aspiration, and the other could not eat orally. A diagnosis of T4 lesions, extensive removal of the tongue base, removal of the geniohyoid and mylohyoid muscles, and removal of the lateral pharyngeal wall were significantly related to poor swallowing function.

In order to investigate the immediate (i.e. within 3h) response of albumin synthesis to the administration of endotoxin, as a model of a moderate and well controlled catabolic insult, two measurements employing L-[2H5]phenylalanine were performed in 16 volunteers. One group (n = 8) received an intravenous injection of endotoxin (4ng/kg; lot EC-6) immediately after the first measurement of albumin synthesis, whereas the other group received saline. A second measurement was initiated 1h later. In the endotoxin group, the fractional synthesis rate of albumin was 6.9±0.6%/day (mean±S.D.) in the first measurement. In the second measurement, a significant increase was observed (9.6±1.2%/day; P<0.001). The corresponding values in the control group were were 6.6±0.6%/day and 7.0±0.6%/day respectively (not significant compared with first measurement and P<0.001 compared with the second measurement in the endotoxin group). The absolute synthesis rates of albumin were 148±35 and 201±49mg·kg-1·day-1 before and after endotoxin (P<0.01). In the control group, the corresponding values were 131±21 and 132±20mg·kg-1·day-1 (not significant compared with the first measurement and P<0.01 compared with the second measurement in the endotoxin group). In conclusion, these results indicate that albumin synthesis increases in the very early phase after a catabolic insult, as represented by the administration of endotoxin.

We report a case of a woman with pregnancy-related thrombotic thrombocytopoenic purpura/haemolytic uraemic syndrome (TTP/HUS) who developed cerebral vasospasm similar to that seen in the other pregnancy-related thrombotic microangiopathic syndromes of eclampsia and HELLP syndrome. A further complication in this case was the development of a focal intracerebral haemorrhage necessitating surgical removal. Despite a successful evacuation of the haematoma and several plasma exchange treatments she developed recurrent haemolysis and thrombocytopoenia with an eventual fatal outcome due to severe pulmonary and gastrointestinal haemorrhage.

Mercury Capture

Copper oxide (CuO) is proved to be a potential adsorbent for elemental mercury in the flue gas emitted from coal-fired power plant. However, the O-terminated CuO(110) surface has relatively week adsorption capacity for Hg. In this work, the doped method is applied to enhance the mercury adsorption capacity of O-terminated CuO(110). Mn, Si, Ti, Al and Zn are selected as the doped atom. It is found that only Zn-doped CuO (110) surfaces have the higher adsorption energy than the pure O-terminated CuO(110) surface. The mercury adsorption capacity is a complex issue, which depends on a combination of oxygen and doped element. The results suggest that the lower electropositive doped element is favorable for the improvement of mercury adsorption capacity. However, the lower electronegativity of oxygen atoms does not facilitate the mercury capture, which is different from the organic material. Cu and doped metal element, rather than oxygen atom, mainly determine mercury adsorption capacity of O-terminated CuO(110) surface, which leads to the lower adsorption capacity of the O-terminated CuO(110) surface than the Cu-terminated CuO(110) surface. The conclusions can also offer a valuable reference for the other metal oxide regarding mercury capture.

ABSTRACT Corticotrophin release in mice was determined from plasma free corticosteroid levels. The blocking effect of dexamethasone against non-specific stress was compared with that of pentobarbital-morphine. In marked contrast to the findings in the rat, pentobarbital-morphine pretreatment in mice did not prevent the activation of the pituitary-adrenal hormonal system, following the non-specific stress of histamine injection. Pentobarbital-morphine thus does not render the mouse a specific in vivo preparation for the determination of corticotrophin releasing activity (CRA). Dexamethasone, on the other hand, appears to be effective in blocking corticotrophin release due to non-specific stress and allowed of activation of the pituitary-adrenal system after intravenous injection of vasopressin and hypothalamic extract only. The steroid had no direct effect on the adenohypophysis.

Rule Out

In rabbits, after rapid intravenous injection of Mg28, the plasma and urinary specific activities, corrected for transit time, are at all times in equilibrium. Injection of Mg28 during stop flow does not reveal any tubular zone permeable to magnesium. On the other hand, the magnesium behavior is in many ways comparable to that of a glomerular substance. These three arguments lead to the view that urinary magnesium is of essentially glomerular origin, and rule out any mechanism of tubular exchange or secretion.

Abstract The platelet-clumping substance appeared statistically significant (p < 0.01 ∼ 0.05) in the heparinized plasma of 29 rabbits collected 5 minutes, 30 minutes, and 1 and 2 hours after the intravenous injection of either 5 ml./Kg. of 0.5 per cent agar-saline solution, 100 µg./Kg. of bacterial endotoxin derived from Escherichia coli, or 10 µg./Kg. of adrenaline, as compared with that in the platelet-saline suspension from the other 36 rabbits. At the same time, the circulating platelet count decreased significantly (p<0.01 ∼0.05). Twenty-four hours after the injection these changes disappeared. The platelet-clumping substance was detected only in heparinized plasma, and not in citrated, oxalated, and EDTA-plasma or serum. The addition or removal of calcium or magnesium ions did not affect the appearance of clumping of platelets. It is stable for storage at 4 C. and is not dialyzable. It induced clumping of platelets not only in the platelet-saline suspension, but also in the platelet-rich plasma, while ADP, serotonin, catecholamine or thrombin (0.001 ∼ 100µg./ml. or units/ml.) did not induce clumping of washed rabbit platelets even under the presence of the normal platelet-free heparinized plasma.

Abstract. Intravenous injection of 10.0 μg/kg body weight synthetic corticotropin (1-24 ACTH) into chronically cannulated boars resulted in significantly elevated plasma corticosteroid and testosterone levels between 20 and 140 min (corticosteroids) and 20–80 min (testosterone) after injection. Administration of lysine-vasopressin (LVP) at doses of 0.1, 0.2 and 0.4 IU/kg body weight elicited a significant increase of plasma corticosteroids between 20 and 40 min after injection; on the other hand, plasma testosterone concentrations tended to fall when compared to pre-treatment levels. From our results it can be concluded that exogenously applied ACTH can effectively stimulate the release of corticosteroids and testosterone. Intravenous administration of LVP results in significantly, although not maximally increased plasma corticosteroid concentrations; the release of endogenous ACTH induced by LVP injection, on the other hand, appeared to be too small to stimulate testosterone release significantly.

Quantitative Distribution

The distribution of manganese dioxide particles 1 hour following intravenous injection in cats, dogs, rabbits, guinea pigs, rats, chickens, and turtles is described. This distribution is remarkably constant for all the animals tested, except the cat, in which the injected material is practically equally divided between the lungs and liver. In the other animals the liver performs the main share of the work, and in the cat it has been shown that the liver after 12 hours accumulates the manganese which was formerly deposited in the lungs. The results are in harmony with experiments in which bacterial suspensions are employed for injection and confirm the suggestion previously made (2) that in the first handling of foreign particulate material the animal behaves similarly whether protein or inorganic injections are used.
