Abstract
Due to concerns about high I in milk, the dairy industry has proposed a voluntary standard of 500 micrograms of I/L as the maximum allowable I in milk sold for processing and human consumption. This study was undertaken to determine the amount of ethylenediamine dihydroiodide that could be fed to dairy cattle without exceeding this standard. Various amounts (0 to 45 mg/head per d) of the I compound were fed to a commercial dairy herd for 50 wk. Individual and bulk milk samples were analyzed for total iodine. Milk I in herd bulk milk was directly correlated (r = .92) with the amounts fed. However, the correlation of milk I of individual cows was not as high (r = .66), indicating some individual variation in metabolism and secretion of the I into the mammary gland. Milk production and number of lactations did not correlate with I in milk. Regression analysis indicated that 25 to 30 mg of ethylenediamine dihydroiodide per day can be fed to dairy cattle receiving a diet otherwise low in I without exceeding a 500 micrograms concentration in milk.

Abstract
UNLABELLED In study I, carried out on 9 asthmatics to investigate whether the bronchodilator and protective effect of intravenous theophylline, dissolved in ethylene diamine (T.E.) or proxyphylline and diprophylline (T.P.D.), showed different dose-effect relationships, 100 mg theophylline with T.E., T.P.D. or NaCl (placebo) were infused 5 times at 30 minute intervals. This was followed by inhalation of 0.4 mg fenoterol. Results showed that the bronchodilator effect of 500 mg theophylline with a serum concentration greater than 15 mg/l was only about 60% of that for fenoterol alone. In study II, 11 patients with exercise-induceable respiratory obstruction received 200 and 351 mg theophylline with T.E., 200 mg with T.P.D. or placebo prior to exercise and cold air inhalation. Here theophylline had a dose-dependent protective effect. With a theophylline serum concentration of 5 mg/l there was already a reduction in exercise asthma by more than 60% in comparison to placebo. At comparable serum concentrations the effect of T.P.D. was better than T.E. in both studies although the difference was not statistically significant. CONCLUSION Since the bronchodilator effect of methylxanthines is less than the protective effect, the prophylactic use of theophylline should be given more attention.

Abstract
Antimicrobial activities of three phenolic compounds and four metal chelators were tested at 0, 250, 500, and 1000 ppm in vitro against four major mastitis-causing bacteria, Streptococcus agalactiae, Staphylococcus aureus, Klebsiella pneumoniae, and Escherichia coli. Overall, butylated hydroxyanisole and tert-butylhydroquinone showed the greatest antimicrobial activity. These phenolics were bactericidal at 250 to 500 ppm against all four bacteria tested. The butylated hydroxytoluene was bactericidal against the gram-positive bacteria but was ineffective against the coliforms. At 250 ppm, disodium ethylenediaminetetraacetic acid was bactericidal against the gram-positive bacteria but much less effective against the gram-negatives. However, diethylenetriaminepentaacetic acid was more growth inhibitory than ethylenediaminetetraacetic acid against the gram-negative bacteria and especially against Escherichia coli. All other compounds were generally much less effective or ineffective against all four microorganisms. Therefore, butylated hydroxyanisole, butylated hydroxytoluene, tert-butylhydroquinone, ethylenediaminetetraacetic acid, and diethylenetriaminepentaacetic acid may have practical implications in the prevention or treatment of bovine mastitis.

Abstract
Of 35 potential iron chelators screened for in vivo activity in rats, a group of phenolic compounds with excellent chelating properties were identified. These included N,N'-ethylene-bis(o-hydroxyphenylglycine) (EHPG), N,N'-Bis(o-hydroxybenzyl)-ethylenediamine diacetic acid (HBED), and their respective dimethyl esters (dmEHPG and dmHBED). All four phenolic compounds produced a marked increase in the fecal excretion of hepatocellular radioiron. This amounted to 42% of total body radioactivity with dmEHPG, 58% with EHPG, 63% with HBED, and 80% with dmHBED after a single injection of 40 mg/animal. At a dose of 5 mg/animal, EHPG, HBED, and dmHBED were 9, 12, and 15 times more potent, respectively, than deferoxamine. Both dimethyl esters showed significant oral activity; oral dmEHPG retained 1/3 and dmHBED retained 2/3 of the effect of the same dose given by intramuscular injection. The ester dmHBED combines oral effectiveness with superior chelating ability, selective hepatocellular action, and low apparent toxicity. It may represent a significant advance in the development of new iron chelating drugs.

Abstract
Bulk tank milk samples collected from 175 dairy herds throughout Wisconsin averaged 466 micrograms of iodine per liter with 11% of the samples containing greater than 1000 micrograms per liter. From questionnaires on feeding and management, use of iodine supplements in feed was associated with increased iodine in milk. One gram of ethylenediamine dihydriodide was fed daily for 2 wk to dairy cows with a history of mastitis. Milk iodine increased from 210 to 6225 micrograms per liter. There was no significant effect on somatic cells, mastitis organisms, or incidence of clinical mastitis.

Abstract
Variations were measured of iodine concentrations of milk during complete lactations of 36 Holstein cows from the University of California herd in Davis and 24 Holstein and 12 Guernsey cows from the California State University herd in Fresno. At Davis no iodine was added to the concentrate, whereas at Fresno iodine as ethylene diamine dihydriodide was added to the concentrate at 4 ppm. At Davis, the mean milk iodine concentration was 166 micrograms/kg; at Fresno, the mean milk iodine concentration was 745 micrograms/kg. Holstein milk had higher iodine concentrations than Guernsey milk, 839 versus 554 micrograms/kg. Iodine concentrations of milk increased during lactation for all cows. At Davis, samples taken in the 1st mo of lactation had 105 micrograms/kg compared with 218 micrograms/kg in the 9th mo. At Fresno, samples taken in the 2nd wk of lactation had 183 micrograms/kg, compared with 1017 micrograms/kg in the 40th wk. Addition of as little as 4 ppm ethylene diamine dihydriodide to the concentrate throughout lactation will lead to greatly increased iodine concentrations in the milk, particularly in late lactation.

Abstract
Experiments were conducted in three successive years in which iodide (I) doses of 1.25, 2.5, 5.0 and 7.5 mg/kg body weight were given to 47 dairy cows during the dry period, compared with 16 control cows on basal diets of 1 ppm I. Effects on cows dosed at 1.25 and 2.5 mg I/kg (50 and 100 ppm dry feed) were not different from controls in terms of vitality of calves, changes in plasma thyroxine (T4), plasma triiodothyronine (T3), thyroxine secretion rate and 10-mo milk yields of the lactation after treatment. Cows dosed with 5 and 7.5 mg I/kg (200 and 300 ppm dry feed) averaged 272.8 d gestation, which was significantly shorter than 279.5 d for all cows on lesser I intakes. Abnormal calves at birth were 25% from the two highest I dosages vs 8% from controls plus the two lowest I dosages. Average plasma T4 and T3 decreased on the day of calving by about 30%, while plasma total I increased about 20%. Changes were greatest in cows fed high I dosages for the longest period prepartum. Plasma I and T3 of calves at birth were about three times the concentrations in their dam's plasma and plasma T4 of neonatal calves was four to five times greater than their dams. Highest dosages of I for dams tended to depress plasma T4 and T3 in neonatal calves.

Abstract
Thirty Holstein heifer calves averaging 120 days of age and 102 kg of body weight were allocated to one control and four treatment groups of six each. Iodine, as ethylenediamine dihydriodide, was mixed 1:9 with dextrose and administered once daily atop feed at .625, 1.25, 2.5, or 5.0 mg iodine per kilogram body weight. Calves were housed individually in unheated, well-ventilated barns and fed complete mixed feeds containing less than 1 ppm iodine. Feed intakes were recorded daily and body weights weekly. Jugular venous blood was collected from iodine treated calves at 0, 4, 8, and 12 wk of the experiment and analyzed for iodine, thyroxine, and triiodothyronine of plasma. Feed intake per unit body weight and per unit gain were not significantly different between treated and control calves. However, daily feed intake and average daily gain decreased slightly at the highest iodine intake. Thyroxine and triiodothyronine were not different among treatments. Thyroxine declined in all calves from 0 to 12 wk. Thyroxine of calves fed 5.0 mg of iodine per kilogram body weight decreased more than of calves fed less iodine. Iodine intake as high as 5.0 mg/kg body weight was tolerated without morbidity, although a minor effect on performance and thyroid activity was indicated.

Abstract
The physiological effect of intravenous application of aminophylline on the mechanics of breathing and the gaseous exchange in persons with bronchial asthma was studied in 7 out-patients before, during and up to 90 minutes after intravenous injection of 0,48 g of Euphillin, and the data were related to the respective serum levels of the drug. The patients suffered from long-standing bronchial asthma, generally associated with moderate airways obstruction. The bronchodilating effect of Euphyllin could be substantiated for the whole time of the trial solely in respect of the changes in oscillatory impedence; the other parameters showed only temporary changes which had disappeard by the end of the trial although the serum levels of aminophylline were in the therapeutic range (mean +/- SD: 12,5 +/- 3,0 microgram/ml). The data indicate that in some patients with bronchial asthma the effect of Euphyllin on lung function is unpredictable. The suggestion is made to measure the responsiveness of the patient to aminophylline by means of simple lung function tests in order to decide whether or not other bronchodilatory substances should be aded to the therapy.

Abstract
The use of EDBPHA as a potential iron chelator in cases of hemochromatosis provided impetus for investigating its toxicology. Because a reddish coloration of excreta was observed during subchronic administration of the drug to dogs, measurements of iron concentrations in blood, excreta, and hematopoietic tissues were made. Groups of beagle dogs of both sexes were injected i.v. with EDBPHA doses of 6, 12, or 18 mg/kg or were given capsules containing doses of 30, 100, or 240 mg/kg for 14 days. Control dogs received either saline i.v. or empty gelatin capsules orally. In addition to the monitoring of toxicological effects, iron levels in plasma, urine, feces, liver, spleen, and kidney were monitored before drug, at the end of treatment, and after a 16-day recovery period. In the absence of hemoglobin and hematocrit changes, i.v. EDBPHA reduced renal iron 40% and hepatic iron 15% to 25% without altering splenic iron. Serum iron rose 34% to 54%, urinary iron 80% to 119%, and fecal iron 23% to 41%. Oral EDBPHA did not induce changes in tissue iron or excreta iron, but serum iron was increased 22% to 29%. These alterations in iron concentrations were transient and may be related to iron redistribution and inactivation of drug by liver.

Abstract
The metabolic fate of a new coronary vasodilating derivative of ethylenediamine (ROM--196) labeled with 14C has been studied in Wistar rats. Dynamics of absorption of the preparation, its distribution in tissues and excretion in urine, feces and bile and expiratory air were investigated. The preparation is quickly absorbed from the gastrointestinal tract and readily penetrates to the tissues. It is excreted mainly in the stools and urine.

Abstract
1 The antihistamines mepyramine and halopyramine which have local anesthetic properties, produced a rise in arterial blood pressure followed by a fall, similar to that seen with procaine, when perfused in a 10 mg/ml solution from the lateral ventricle to the cisterna magna in dogs. 2 The pressor response produced by procaine perfused through the cerebral ventricle is due to an action on structures situated in the caudal half of the floor of the fourth ventricle because a pressor response was obtained when a few microlitres of a 50 mg/ml solution of procaine were applied to a small area of the exposed floor of the fourth ventricle in a region 2 to 4 mm rostral to obex, and after cauterization of this area procaine perfused through the cerebral ventricles no longer raised arterial blood pressure. 3 Bilateral denervation of the carotid sinus did not affect the pressor response obtained with procaine perfused through the cerebral ventricles. 4 The pressor response to procaine is mediated through the sympathetic nervous system. It results partly from an increased adrenaline discharge from the adrenal glands and partly from increased sympathetic vasomotor tone, because the response is abolished or attenuated after removal of the adrenal glands and intravenous injections of hexamethonium and phentolamine.

Abstract
14-C labelled MK-142 (specific activity 2.875 muCi/mg) (1.762 mCi/mM) passes very rapidly from the blood stream to the majority of tissues since 5 min after the iv administration the blood contained only about 5% of the administered dose. The relatively high content of MK-142 in the myocardium as compared with its content in the skeletal muscles indicates a high affinity of the examined substance to the heart muscle. MK-142 is excreted via kidneys, alimentary tract and respiratory ways.
