Abstract
The hypothesis was investigated that colloidal ferric or aluminum hydroxides, formed in blood plasma in vivo, potently absorb lead and thus profoundly influence uptake of lead into certain soft tissues. Rats were given 203Pb i.v. to obtain a near constant plasma level of 203Pb. Tissue uptake of 203Pb at 1 hr was determined with and without the i.v. infusion of 5.0 mM ferric chloride or 5.0 mM aluminum chloride. Infusion of Fe chloride or Al chloride suppressed the uptake of 203Pb into brain, cerebrospinal fluid, skeletal muscle, kidney and red cells by 70 to 94%. In contrast, the uptake of 203Pb into liver and spleen was not significantly reduced, in the case of spleen being greater after Fe chloride or Al chloride infusion. The latter increases were not statistically significant. After ultracentrifugation, greater than 70% of plasma 203Pb activity was associated with the hydroxide-protein pellet (Fe chloride and Al chloride experiments). The ultrafilterable 203Pb in such sera was reduced by greater than 90% compared with controls. By the use of the lead electrode in vitro, lead adsorption to ferric hydroxide was confirmed. Thus, in vivo formation of colloidal hydroxides must occur under the authors' conditions, leading to a reduction of ionized lead in plasma and lower uptake where this depends on free lead and comparable or enhanced uptake into tissues containing reticuloendothelial cells capable of phagocytosis.

Abstract
Both chicken liver NADP-malic enzyme and Ascaris suum NAD-malic enzyme catalyze the metal-dependent decarboxylation of oxalacetate. Both enzymes catalyze the reaction either in the presence or in the absence of dinucleotide. The presence of dinucleotide increases the affinity of oxalacetate for the chicken liver NADP-malic enzyme, but this information could not be obtained in the case of A. suum NAD-malic enzyme because of the low affinity of free enzyme for NAD. The kinetic mechanism for oxalacetate decarboxylation by the chicken liver NADP-malic enzyme is equilibrium ordered at pH values below 5.0 with NADP adding to enzyme first. The Ki for NADP increases by a factor of 10 per pH unit below pH 5.0. An enzyme residue is required protonated for oxalacetate decarboxylation (by both enzymes) and pyruvate reduction (by the NAD-malic enzyme), but the beta-carboxyl of oxalacetate must be unprotonated for reaction (by both enzymes). The pK of the enzyme residue of the chicken liver NADP-malic enzyme decreases from a value of 6.4 in the absence of NADP to about 5.5 with Mg2+ and 4.8 with Mn2+ in the presence of NADP. The pK value of the enzyme residue required protonated for either oxalacetate decarboxylation or pyruvate reduction for the A. suum NAD-malic enzyme is about 5.5-6.0. Although oxalacetate binds equally well to protonated and unprotonated forms of the NADP-enzyme, the NAD-enzyme requires that oxalacetate or pyruvate selectively bind to the protonated form of the enzyme. Both enzymes prefer Mn2+ over Mg2+ for oxalacetate decarboxylation.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
In order to examine possible selectivity of amine uptake by synaptic vesicles, the ATP-stimulated accumulation of 3H-5-hydroxytryptamine (5HT) by synaptic vesicles from rat whole brain was examined in a medium comprised largely of membrane-impermeant anions (d-tartrate). Such media have previously been shown to stabilize vesicular accumulation of several neurotransmitters. Accumulation of 3H-5HT did not occur in tartrate medium alone, but was increased biphasically with increasing concentrations of both potassium phosphate and potassium bicarbonate. At optimal concentrations of each anion (10 mM), stable accumulation of 3H-5HT was observed at 37 degrees (26.1 +/- 1.2 pmol/mg protein; Km 6 X 10(-7) M), which was reduced by greater than 95% in the absence of K2ATP, at 4 degrees C, in the presence of 10(-6) M reserpine, or in the presence of the proton ionophore carbonyl cyanide p-trifluoromethoxyphenylhydrazone (FCCP). Uptake was significantly antagonized by millimolar concentrations of Na+, Mg++ or Cl-, but was unaffected by ouabain (10(-5) M). Pretreatment of animals with 5,7-dihydroxytryptamine (5,7-DHT) (200 micrograms, intraventricular) 10 days prior to sacrifice reduced endogenous 5HT levels by 70%, while levels of endogenous norepinephrine (NE) and dopamine (DA) were unaffected. Accumulation of 3H-5HT, examined in the presence of 10(-6) M NE to block 3H-5HT accumulation by vesicles from noradrenergic nerve endings, was reduced by 40% in vesicles from treated animals. Vesicular accumulation of 3H-(-)-NE and 3H-DA was unaffected by 5,7-DHT treatment. The data suggest the possibility of preferential accumulation of 3H-5HT by vesicles arising from serotonergic nerve endings.

Abstract
To assess the role and responses of lipoperoxide and superoxide dismutase in hypertensive disease, the serum and erythrocyte lipid peroxide and erythrocyte superoxide dismutase levels were measured in 65 normal persons and hypertensive patients. The results are summerized as follows: In normal persons, serum and erythrocyte lipoperoxide values showed an increase according to age, but the elevation was not statistically significant. In normal persons, the erythrocyte superoxide dismutase value did not change according to age. In hypertensive patients, the serum and erythrocyte lipoperoxide values showed increases of 10.8% and 26% respectively compared to those of the controls. In hypertensive patients, the erythrocyte superoxide dismutase value showed a decrease of 29.9% compared to that of the controls.

Abstract
Computed tomographic (CT) studies were correlated with microscopic findings in 10 histologically verified cavernous hemangiomas in nine patients. In four of the 10 lesions, two or more distinct types of cerebrovascular malformations were identified histopathologically. These included arteriovenous malformations, venous malformations, and telangiectasis. Such coexistence of various types of cerebrovascular malformations has been reported rarely. In each of the four combined lesions, there was evidence of recent or old hemorrhage. The CT findings were nonspecific and were similar to those seen in a variety of intracranial pathologic conditions.

Abstract
Measurement of the initial rate of the malic enzyme reaction varying the concentration of NAD at several different fixed levels of Mg2+ (0.25-1.0 mM) and a single malate concentration gave a pattern which intersects to the left of the ordinate. Repetition of this initial velocity pattern at several additional malate concentrations and treatment in terms of a terreactant mechanism suggests an ordered mechanism in which NAD adds prior to Mg2+ which must add prior to malate. On the other hand, when a broader concentration range of Mg2+ (0.25-50 mM) is used, data are consistent with a random mechanism in which Mg2+ must add prior to malate. By use of product inhibition studies, pyruvate is competitive vs. malate and noncompetitive vs. NAD, while NADH is competitive vs. NAD and noncompetitive vs. malate. These results are consistent with the random addition of substrates and further suggest rapid equilibrium random release of products. Tartronate, a dead-end analogue of malate, is competitive vs. malate and noncompetitive vs. NAD. Thio-NAD is a slow substrate which is used at 2.4% the maximum rate of NAD. When used as a dead-end analogue of NAD, thio-NAD is competitive vs. NAD and gives a complex inhibition pattern vs. malate in which competitive inhibition is apparent at low concentrations of malate (less than 12.5 mM), and this changes to uncompetitive inhibition at high concentrations of malate (greater than 12.5 mM). These data are consistent with a steady-state random mechanism in the direction of oxidative decarboxylation in which Mg2+ adds in rapid equilibrium prior to malate.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The influence of tracheal lavage with an allergen on the airway response to bronchial challenge with histamine, acetylcholine, and ascaris extract was investigated in 36 dogs. High histamine concentrations were measured in the tracheal solution after lavage with allergen. This amine, released on the mucosal surface, was observed in only very small concentrations in the circulation. Airway response to acetylcholine inhalation was significantly increased after tracheal lavage with allergen. This hyperreactivity of the lower airways induced by tracheal lavage with an allergen suggests that a reflex mechanism is involved. After histamine inhalation a significantly larger antigen-induced histamine release to tracheal lumen was observed. No influence on airway response was found after tracheal lavage with H2O.

Abstract
The influence of tracheal lavage in a restricted area, with a proteolytic enzyme (Pronase) on the bronchial response to challenge with ACH and AE was studied in 15 dogs. Histamine concentrations measured in the tracheal liquid after lavage with Pronase were smaller than the values after tracheal lavage with allergen. Airway response to ACH inhalation was significantly increased after tracheal lavage with Pronase. Effects of proteolytic enzymes and allergens on the tracheal wall are compared. Allergens and proteolytic enzymes evidence a different mode of action in increasing reactivity of peripheral airways.

Abstract
The influence of tracheal lavage with compound 48/80 on the bronchial response to challenge with ACH and AE was studied in 24 animals. Furthermore, the effect of i.v. administration of 48/80 was compared to its administration into the tracheal lumen. No increased histamine liberation was detected in the tracheal fluid after lavage with 48/80, nor was an influence on the bronchial response observed. These observations were the same as those described for tracheal lavage with water. The same amounts of this secretagogue induced, after i.v. administration, a high histamine release which correlates significantly with blood pressure decrease.

Abstract
The sputa of patients with chronic obstructive lung disease show high histamine concentrations with large individual variations. The fluorometric and the biologic method correlate statistically significantly. Histamine concentrations decrease significantly, during 60 min at 37 degrees C, by different amounts in different patients. The measured histamine concentration can cause bronchoconstriction. The histamine and the NaCl control solutions have been found to liberate histamine into the blood, measured as free plasma histamine. There are still many questions open which should be solved because the histamine concentration in the sputum could play an important role in chronic obstructive lung disease.

Abstract
In 656 patients aged from one to 39 years, the incidence of axonal dystrophy in the gracile nucleus (ADG) is correlated with underlying diseases. The age-related incidence of ADG (minimal to severe) in these patients, 13, 53, 76 and 97% in the first, second, third, and fourth decades, respectively, is comparable to that observed by other investigators. The incidence drops to 8, 16, 31, and 60% when more than five spheroids in each gracile nucleus are taken into account. Diseases with which ADG is frequently associated vary according to the patient's age. Congenital biliary atresia and cystic fibrosis account for 71% of cases of ADG (mild to severe) in the first decade, while cystic fibrosis and malignancies account for 38 and 35% in the second decade, respectively. In the third decade, malignancies, renal diseases, cystic fibrosis, and heart diseases account for 30, 14, 12, and 12% of ADG cases, respectively, while malignancies, renal diseases, heart diseases, and diseases of digestive organs account for 30, 24, 15, and 11% in the fourth decade, respectively. The incidence of ADG also increases progressively with age, duration of the clinical course in the individual disease, or both, regardless of types of the diseases. This fact, when viewed together with the precocious development of severe ADG in patients with the malabsorption syndromes and in those with grave illnesses with protracted course leading to cachexia, seems to indicate that malnutrition represents a common factor correlated with severe ADG in the young patients. It seems to be premature at this time to disregard the hypothetical question that ADG in man is in some way related to deficiency or altered metabolism of vitamin E.

Abstract
In 63 patients with malabsorption syndromes, 16 with congenital biliary atresia (BA) and 47 with cystic fibrosis (CF), axonal dystrophy in the gracile nucleus (ADG) was studied. Of the 16 patients with BA, ADG of considerable severity was observed in all 10 over one year of age. Of the 47 patients with CF, it was observed in 32, 61 and 80% of the cases in the first, second, and third decades, respectively. Evidence is presented that there has been a substantial decrease in the incidence of ADG in CF patients in recent years and that the decreased incidence is attributable to vitamin E (Aquasol E) therapy. The beneficial effect of vitamin E supplementation in CF patients is proffered as strong evidence that ADG in BA and CF is related to vitamin E deficiency. The present study indicates that BA and CF patients require vitamin E supplementation to maintain a normal integrity of axons related to the gracile and perhaps other sensory nuclei. Critical neurological evaluation for possible dysfunction of the sensory nuclei in these patients with malabsorption syndromes is advised.
