Haemoglobin synthesis following injection of iron-poly (sorbitol-gluconic acid) complex, Ferastral.

Ferastral, a new iron-poly (sorbitol-gluconic acid) complex for parenteral use has been given to 22 patients with iron deficiency anaemia. The patients were divided in two groups. Group I received a suboptimal dose of Ferastral iron corresponding to 90% of the iron calculated to normalize the haemoglobin value. Increases in total haemoglobin and also blood losses were measured. The availability of the injected iron for haemoglobin synthesis ranged from 63% to 111%. Group II received an amount of Ferastral-iron calculated to be necessary for normalization of the haemoglobin plus an additional 500 mg of Ferastral-iron. In this group the haemoglobin increase was rapid. In 7 weeks 10 out of 14 patients had reached a normal haemoglobin level.

Iron-poly (sorbitol-gluconic acid) complex and iron-dextran in the treatment of severe iron deficiency anaemia.

An investigation has been carried out to study the efficacy of iron-poly (sorbitol-gluconic acid) complex (Ferastral) in the treatment of iron deficiency anaemia. Ferastral was given by the intramuscular route every second or third day in a dose of 500 mg, divided in two injections. These were compared with the results of a group treated with iron-dextran given by Total Dose Infusion (TDI). A total of 38 patients were treated with either Ferastral or iron-dextran by TDI, respectively, given according to random allocation. The total dose of iron given in both groups was 1 500 mg of elemental iron. The parameters investigated were haematocrit and haemoglobin. Side-effects were also recorded. The results in the group treated with Ferastral where the mean initial haemoglobin value was 9.5 g/100 ml showed a mean haemoglobin increase to 13.2 g/100 ml after eight weeks. Initial haemoglobin values and haemoglobin increase for iron-dextran by TDI were quite similar. Three patients in the Ferastral group had transient discolouration at the site of injection and one patient in the iron-dextran TDI-group had a serious allergic reaction.

Escherichia coli K-12 structural kdgT mutants exhibiting thermosensitive 2-keto-3-deoxy-D-gluconate uptake.

A specific method is described for selecting thermosensitive mutants of Escherichia coli K-12 able to grow on 2-keto-3-deoxy-D-gluconate (KDG) and D-glucuronate at 2, but not at 42 degrees C. The extensive analysis of one such mutant is consistent with the conclusion that the carrier molecule responsible for KDG and glucuronate uptake becomes thermolabile. (i) Growth on a variety of carbon sources is perfectly normal at 28 and 42 degrees C, whereas in the same temperature range it gradually diminishes on KDG and glucuronate. (ii) The apparent Km value for KDG is about twofold in the range 25 to 40 degrees C. In the same temperature range, the Vmax values for KDG influx are higher for the mutant compared with those of the wild-type strain, but the optimum temperature is 34 degrees C instead of 38 degrees C. On the contrary, the Vmax values for glucuronate influx are lower for the mutant than for the parental strain, and the optimum temperature for both strains is shifted beyond 40 degrees C. (iii) The activation energies for KDG and glucuronate uptake are about twofold higher in the mutant than in the wild-type strain. (iv) Kinetics of counterflow under deenergized conditions (overshoot) at different temperatures indicate that the defect is located in the translocation step rather than in the processes involved in energy coupling. (v) The first-order rate constants for thermal denaturation are, respectively, 2.5- and 5-fold higher at 40 and 30 degrees C in the mutant than in the wild-type strain, and the activation energy for thermal denaturation is lower. (vi) The carrier molecule in the mutant is also much more sensitive to denaturation by N-ethylmaleimide. (vii) Four independent thermosensitive mutations and one revertatn were located by transduction in or near the kdgT locus, defined previously as the site of nonconditional KDG transport-negative mutations. These results support the conclusion that kdgT represents the structural gene coding for the KDG transport system.

Effects of oral calcium gluconate on gastric acid secretion and serum gastrin concentration in man.

A single oral dose of 4-46 mmol calcium gluconate at pH 5-6 was administered intragastrically to 15 male volunteers without gastrointestinal disease. There was a significant rise in acid output from 30-90 minutes after the calcium was given compared with the basal hourly collection. The serum gastrin level 30 minutes after calcium administration was significantly raised, but no correlation could be demonstrated between the acid and gastrin responses. Serum calcium levels were unchanged throughout. An equimolar dose of magnesium sulphate had no such effects. This study suggests that the intragastric administration of calcium results in independent release of gastric acid and gastrin from the gastric mucosa.

Zinc gluconate and the common cold: a controlled clinical study.

A report in 1984 on the success of zinc gluconate against common cold symptoms could not be confirmed in three subsequent studies, which are now known to have used formulations that inactivated zinc. A non-chelating formulation including glycine, which releases 93% of contained zinc into saliva, was tested in a randomized, placebo-controlled, double-blind trial in 73 young adults. Efficacy was recorded in symptom diaries using a symptom severity rating. Patients' symptoms first appeared 1.34 days prior to entry to the study in both groups. Disappearance of symptoms occurred after an additional 4.9 days for zinc-treated patients versus 6.1 days for placebo-treated patients. A difference was noted in the efficacy of treatment if it was started 1 day after symptom onset: cold duration was an additional 4.3 days in zinc-treated patients compared with 9.2 days for placebo-treated patients. Cough, nasal drainage and congestion were the symptoms most affected, and only mild side-effects were noted.

The effect of chlorhexidine gluconate on the formation of experimental granulation tissue.

The aim of the study was to investigate the effect of chlorhexidine gluconate on the connective tissue formation. Granulation tissue was produced with a method in which sponges were inserted beneath the back skin of rats. Dry sterilized sponges were impregnated either with 0.45% NaCl solution (control) or or 0.2% chlorhexidine solution [test]. The sponges were removed after 3, 5, 7, 10, 14, 19 and 23 days. The content of hydroxyproline, hexosamines, DNA and RNA was estimated from the sponges. The acid glycosaminoglycans were further purified and analyzed. The results of the study indicate that chlorhexidine had a clear delaying effect on the formation of granulation tissue.

Effect of chlorhexidine gluconate on acute nonmicrobial inflammation reaction.

The effects of chlorhexidine on the appearance of leukocytes and some hydrolytic enzymes were studied in an experimental acute nonmicrobial inflammation reaction caused by implanation of viscose sponge beneath the backskin. The results showed that chlorhexidine gluconate decreased the number of leukocytes in the inflammatory exudate. The drug used had no measurable effect on the distribution of different types of leukocytes. Chlorhexidine has a clear inhibitory effect on the appearance of phosphatases, glycosidases and peptidases. On the other hand the effect on proteinases was small.

[Studies of intrarenal distribution by macroautoradiogram and tissue distribution of 99mTc-gluconate (author's transl)].

1) The experimental studies have demonstrated that 99mTc-gluconate reaches a high concentration in the kidneys within 1-2 hours after injection and its concentration in organs adjacent to the kidney is low. 2) The initial images of serial macroautoradiograms visualized the inner medulla as well as the cortex and outex medulla, whereas the delayed images revealed only the outer cortex and outer stripes in the outer medulla. These findings suggest that this renal agent consists of two components and the delayed component deposits in the convoluted and straight segments of proximal tuble. 3) This renal agent visualizes the calyceal system and excretory pathways in the initial study and the renal morphology in the delayed study. Therefore, using this renal agent, it may be possible to evaluate a variety of renal diseases, including obstructive uropathy, space-occupying lesions, congenital deformities, etc,.

Membrane-bound D-gluconate dehydrogenase from Pseudomonas aeruginosa. Purification and structure of cytochrome-binding form.

A membrane-bound D-gluconate dehydrogenase [EC 1.1.99.3] was solubilized from membranes of Pseudomonas aeruginosa and purified to a homogeneous state with the aid of detergents. The solubilized enzyme was a monomer in the presence of at least 0.1% Triton X-100, having a molecular weight of 138,000 on polyacrylamide gel electrophoresis or 124,000--131,000 on sucrose density gradient centrifugation. In the absence of Triton X-100, the enzyme became dimeric, having a molecular weight of 240,000--260,000 on sucrose density gradient centrifugation. Removal of Triton X-100 caused a decrease in enzyme activity. Enzyme activity was stimulated by addition of phospholipid, particularly cardiolipin, in the presence of Triton X-100. The enzyme had a cytochrome c1, c-554(551), which might be a diheme cytochrome, and it also contained a covalently bound flavin but not ubiquinone. In the presence of sodium dodecyl sulfate, the enzyme was dissociated into three components with molecular weights of 66,000, 50,000, and 22,000. The components of 66,000 and 50,000 daltons corresponded to a flavoprotein and cytochrome c1, respectively, but that of 22,000 dalton remained unclear as to its function.

Subcutaneous calcium deposition in the neonate associated with intravenous administration of calcium gluconate.

Nine infants who had severe local manifestations following intravenous administration of calcium gluconate are presented. The lesions appeared at the intravenous sites as firm subcutaneous nodules or areas of areas of inflammation with central softening and fluctuation. The interval between appearance of the lesion and calcium administration was 13 plus or minus 2.5 (mean plus or minus SEM) days. Five infants were treated with antibiotics and three of the five had incision and drainage. Roentgenographic evidence of subcutaneous calcification was seen in all cases at the time the lesions were first noticed. In two infants the entire cephalic vein was calcified. Induration and inflammation completely subsided in six infants, four of whom had follow-up roentgenograms showing complete resolution of calcification. A conservative approach in management is recommended.

Are there therapeutic indications of intravenous injection of calcium gluconate?

1. The action of i.v. injection of calcium gluconate on a) the release of catecholamines from the adrenals of cats and dogs, b) the adrenergic responses of circulation, nictitating membrane and spleen in cats, and c) the cardiac and circulatory response in dogs has been investigated. 2. Ca2+-effects mediated by release of catecholamines dominate in the cat, as do direct cardiac stimulating actions in the dog. 3. Ca2+-effects of therapeutic significance, if existent at all, could be assumed only with regard to an anti-anaphylactic effect of the catecholamines released by i.v. injected Ca2+.

Plasma ionic calcium levels following injection of chloride, gluconate, and gluceptate salts of calcium.

The ionic equivalency of three calcium salts was tested in 15 patients undergoing cardiac surgery with extracorporeal circulation. Of the three salts tested (chloride, gluconate, gluceptate), only calcium chloride showed a reproducible and highly significant relationship between the increase in total calcium and the increase in ionic calcium. It is suggested that extracorporeal circulation may be one clinical situation in which use of a calcium electrode may be of major value. The marked distortion of plasma proteins and pH, the addition of large amounts of citrate, and the differences between various calcium salts indicate that it is probably not possible to predict ionic calcium with assurance and that direct measurement may be necessary for optimal therapy.

[Sequential renal scintiscanning with 99mTc calcium gluconate. Possibilities and limitations].

The methods used in the study of the kidney are discussed and sequential scintiscanning is suggested as a means of supplementing purely morphological data with morpho-functional data. An account of the modalities employed with a variety of radio-compounds and reasons are proffered for the choice of 99mTc calcium gluconate. Results obtained with this method are described. These include the acquisition of information concerning the function and shape of the renal parenchyma and urinary tracts. Organic classification of the results will be dealt with in a later paper. It is felt that the method proposed is a valuable diagnostic aid with interesting possibilities in the study of diseases of the urinary apparatus.
