Treatment of allergy to house dust with pyridine-extracted alum-precipitated extracts of the house dust mite.

Two preliminary trials in which patients with respiratory allergy to the house dust mite were treated with pyridine-extracted alum-precipitated extracts of house dust mites are described. In the first, using an extract of D. farinae, twenty-two of twenty-eight asthmatic patients improved. In the second, using an extract of D. pteronyssinus, fifteen of eighteen asthmatic patients improved.

Inhibition of aluminium toxicity by magnesium and citric acid in tobacco tissue culture.

Using tobacco callus tissues the authors studied the antagonism of magnesium and aluminium, and the inhibition of aluminium toxicity by magnesium and citric acid, as expressed by their effect on growth and alkalod content. In response to an increase in the concentration of MgSO4 in the culture medium the fresh weight of the cultures significantly increased, while with an increase in Al2(SO4)3 growth decreased, 2 mM causing a high degree of inhibition. The toxic effect of aluminium was less marked when Mg was present at a concentration higher by an order (antagonistic inhibition). When citric acid was added to the culture medium, promoting complex formation with Al, the toxic effect of Al was not apparent. The nicotine content of the tissues was in each case inversely correlated with the magnitude of biomass formation.

Encephalopathy and seizures induced by intravesical alum irrigations.

Hemorrhagic cystitis is a significant toxic effect of cyclophosphamide therapy. Continuous bladder irrigation of a 1% alum solution is a simple and generally safe method of chemical cautery to treat the bleeding urothelium. We report four cases of encephalopathy coincident with elevated aluminum levels as well as one patient who developed seizures while receiving continuous bladder irrigations with alum. All patients had significant renal insufficiency. We recommend the cautious use of alum irrigation in patients with renal impairment and monitoring of serum aluminum levels to prevent excessive accumulation and toxicity.

Physico-chemical investigation of AlPO4 for the manufacture of antacids. I. Effect of precipitation and processing conditions on physico-chemical properties of AlPO4.

Aluminium phosphate was precipitated from AlCl3-H3PO4 and NaOH, NH3H2O and NaHCO3--Na2CO3 mixture up to different pH values. The precipitates were dried at room temperature, 40 degrees and 105 degrees and their neutralizing properties (rate of neutralization and acid-consuming capacity) against 0.l N HCl were investigated. It was found that these properties depend on the nature of the reagents used for the formation of AlPO4, the pH and also the temperature of drying. The best antacid properties shows the AlPO4 preperation obtained from AlCl3-H3PO4 and NaHCO3-Na2CO3. For comparison, the therapeutic preparate "Aluphos" was also investigated.

Prolonged immunotherapy with alum-precipitated pyridine ragweed extracts-a clinical and immunological study.

In 18 ragweed hay fever patients who received injections of alum-precipitated pyridine (Allpyral) ragweed extracts in maintenance doses of between 6000 and 8000 P.N.U. at intervals of between two and four months over a two-year period, the prolonged interval did not seem to influence either the clinical response or the tendency to reaction, or result in significant change in immunological tolerance as determined by antibody studies, which included fluorescent antibody assays, as well as hemagglutination and RAST technics.

[Acetlysalicylic acid, protective antacid effect and lesions of the gastric mucosa. Effect of acetylsalicylic acid and an antacid drug (Gastropulgit Tabs) on the transmural electric potential in the human stomach].

Antacids are able to prevent acetylsalicylic acid-induced functional and morphological changes of the gastric mucosa. In order to test whether a new antacid in chewing-tablet form (Gastropulgit Tabs) might be able to protect the gastric mucosa from acetylsalicylic acid-induced functional changes similarly to liquid antacids the effect of this antacid on acetylsalicylic acid-induced changes of transmural gastric potential difference was measured in healthy volunteers. The decrease of transmural potential differences induced by 640 mg acetylsalicylic acid could be prevented by simultaneous addition of 2 tablets of Gastropulgit Tabs. Thus the antacid in tablet form is able-like liquid antacids-to protect the gastric mucosa against acetylsalicylic acid-induced functional changes.

Absorbances of hematoxylin solutions at varying pH levels.

An alum hematoxylin was prepared (0.5 g hematoxylin, 8 g potassium alum, distilled water 477.5 ml and Na10(3) solution, 1 mg/ml, 22.5 ml) and divided into 50 ml aliquots. The pH of these aliquots was adjusted with 2 1/2% NaOH or 10% H2SO4. As soon as the pH of a sample was adjusted the absorbance from 400 to 700 nm was recorded with a Cary 15 spectrophotometer using specially designed cuvettes and undiluted samples. The following day the absorbances at peak were measured on a Coleman Jr. spectrophotometer and three days later a variety of tissues was stained with each solution. The pH and peak of absorbance of the aliquots were pH = 2.0 450 NM, 2.5 505, 2.6 507, 2.7 515, 2.8 520, 2.9 530, 3.0 540, 3.1 550, 3.3 560, 3.5 560. In the stained material in the intensity of nuclear staining was about the same at all pH levels but non-specific staining was greatest in slides stained at pH = .5 and virtually absent in slides stained at pH = 2.0. At intermediate pH levels the amount of non-specific staining was intermediate.
