[Galvanization of a region of the liver in combination with use of huminate in complex recuperative treatment of patients having undergone surgery on the stomach and biliary tract]. / Gal'vanizatsiia oblasti pecheni v sochetanii s priemom guminata v kompleksnom vossanovitel'nom lechenii bol'nykh, perenesshikh operativnye vmeshatel'stva na zheludke i zhelchevyvodiashchikh putiakh.

We studied efficiency of intratissue electrophoresis of 1% huminate solution in rehabilitation of patients operated on the stomach and biliary tracts with functional deficiency of the stress-limiting system (SLS). The above electrophoresis stimulates SLS and promotes earlier start of therapeutic response.

The influence of humic acids derived from earthworm-processed organic wastes on plant growth.

Some effects of humic acids, formed during the breakdown of organic wastes by earthworms (vermicomposting), on plant growth were evaluated. In the first experiment, humic acids were extracted from pig manure vermicompost using the classic alkali/acid fractionation procedure and mixed with a soilless container medium (Metro-Mix 360), to provide a range of 0, 50, 100, 150, 200, 250, 500, 1,000, 2,000, and 4,000 mg of humate per kg of dry weight of container medium, and tomato seedlings were grown in the mixtures. In the second experiment, humates extracted from pig manure and food wastes vermicomposts were mixed with vermiculite to provide a range of 0, 50, 125, 250, 500, 1,000, and 4,000 mg of humate per kg of dry weight of the container medium, and cucumber seedlings were grown in the mixtures. Both tomato and cucumber seedlings were watered daily with a solution containing all nutrients required to ensure that any differences in growth responses were not nutrient-mediated. The incorporation of both types of vermicompost-derived humic acids, into either type of soilless plant growth media, increased the growth of tomato and cucumber plants significantly, in terms of plant heights, leaf areas, shoot and root dry weights. Plant growth increased with increasing concentrations of humic acids incorporated into the medium up to a certain proportion, but this differed according to the plant species, the source of the vermicompost, and the nature of the container medium. Plant growth tended to be increased by treatments of the plants with 50-500 mg/kg humic acids, but often decreased significantly when the concentrations of humic acids derived in the container medium exceeded 500-1,000 mg/kg. These growth responses were most probably due to hormone-like activity of humic acids from the vermicomposts or could have been due to plant growth hormones adsorbed onto the humates.

The effects of dietary humate supplementation on broiler growth and carcass yield.

The growth-promoting effect of Farmagülatör DRY Humate (FH) on live performance, carcass weight, and the abdominal fat pad of broilers was studied during different feeding periods. Four hundred, 1-d-old straight-run birds were randomly distributed to 20 floor pens of an environmentally controlled house. Four dietary regimens were replicated in five pens, each containing 20 chicks, as follows: 1) birds received no added FH in the starter or grower (NAFH), 2) birds received FH from 0 to 21 d (FH0-21), 3) birds received FH from 22 to 42 d (FH22-42), 4) birds received FH from 0 to 42 d (FH0-42) in the starter and grower diets, respectively. The FH was added to the diets at 2.5 kg/per ton of feed. Starter and grower diets were formulated to meet the minimum NRC requirements for broilers and were provided as a mash feed. Body weights at 21 d were not affected by the dietary regimens. At 42 d, body weights and feed conversions of broilers were significantly affected by the dietary humate treatments. Birds fed FH22-42 weighed more than the NAFH, whereas the FH0-21 and FH0-42 were intermediate and not different from the other treatments. Feed:gain was lower for the FH22-42 and FH0-42 treatments compared to the NAFH. There was no difference in carcass yield or abdominal fat pad percentages due to feeding FH. Feeding FH during the grower period had the most beneficial effect in terms of growth and feed conversion on broiler performance.

[The favorable effect of humic acid based complex micro-element preparations in cadmium exposure]. / Huminsav bázisú komplex mikroelem-késítmény kedvezoö hatása kadmiumexpozícióban.

The authors have studied the effect of consumption of a humic acid based complex microelement preparation (potassium, magnesium, iron, zinc, manganese, copper, vanadium, cobalt, molibden, selenium bound to humic acids) for six weeks (10 ml daily) on the biological exposure indices (blood and urine cadmium levels) and clinical laboratory parameters (liver and kidney tests, blood picture) of men (n = 18; 39.7 +/- 10.4 years of age;) working in cadmium exposure for 8.3 +/- 5.0 years. The initial mean blood and urine cadmium levels of the non-smoking subjects was twice higher than that of the non-smoking male controls living in the same urban area (n = 35), and significantly correlated with the length of exposure. Their mean serum alanin-aminotransferase, gamma-glutamyl-transferase, creatinine, uric acid and urinary N-acetyl-beta-D-glucosaminidase levels were significantly higher than that of the controls. After the six-week treatment blood cadmium level, activity of serum alanin-aminotransferase, serum uric acid and urinary protein concentrations decreased significantly, the abnormal serum iron levels normalized. According to this results, the absorption of cadmium decreased on the effect of the complex microelement supplementation and the adverse laboratory changes attributable partly to cadmium exposure improved. Therefore humic acid based complex microelement supplementation is recommended as an effective tool for prevention and health protection in occupational cadmium exposure as well as for smokers known to be considerably burdened by cadmium.

[The resorptive behavior of a low-molecular weight humic substance after a single oral administration to the rat]. / Untersuchungen zum Resorptionsverhalten eines niedermolekularen synthetischen Huminstoffes nach einmaliger oraler Applikation an der Ratte.

By labeling HS 1500 with a radioactive 14C, it was proven that after oral application and under certain circumstances, low amounts of low molecular humic acids are for a short time absorbed from the gastrointestinal tract. But the biological availability of the substance is very low (less than 0.1% of the applied high doses). The plasma concentration curve assumes a first order kinetic for invasion and excretion. After oral application of 500 mg/kg b.w. HS 1500 the half life period was 1.5 hours and maximum plasma concentration was 3 micrograms/ml. The result obtained indicate that HS 1500 is toxicological riskless after oral administration. Taking into account the pharmacokinetic data, residues of the substance in animal tissues can be ruled out with high significance.

The influence of long-term administration of Tolpa Peat Preparation on immune reactivity in mice. III. The effect on primary humoral response to sheep erythrocytes.

Tolpa Peat Preparation (TPP) was administered to mice in daily doses of 1, 10 and 50 mg.kg-1 for 3, 5, 7, 9 or 12 consecutive weeks. After each of the above mentioned periods the primary response to sheep erythrocytes (SRBC) was examined by determination of the percentage of splenocytes forming E rosettes, the number of splenocytes producing anti-SRBC haemolysins of 19S and 7S type, and the level of serum haemagglutinins to SRBC (19S + 7S and 7S types). The effect of enhanced humoral response by TPP was observed in mice immunized with SRBC. This effect depended, first of all on TPP does but also on the duration of time TPP administration. The stimulating effect on the humoral response occurred after the daily dose of 1 mg.kg-1 during 12 weeks. On the other hand, the daily doses of 10 or 50 times higher enhanced the humoral response only during the first 5-7 weeks of TPP administration. Longer administration of TPP in these doses caused disappearance of this effect or reduction of the response to SRBC.

The effect of Tolpa Peat Preparation on the phagocytic and metabolic activity of neutrophils in normothermic rabbits and with pyrogen-induced fever.

The studies on normothermic rabbits show that intravenous administration of Tolpa Peat Preparation (TPP) at a dose of 5 mg/kg for 3 or 6 consecutive days increases the percentage of phagocytizing cells and the number of bacteria phagocytized by a single neutrophil. The stimulated phagocytic activity of neutrophils coincides with increased nitroblue tetrazolium (NBT) reduction. In contrast, a single administration of TPP to rabbits with fever induced by E.coli lipopolysaccharide (LPS) has a modulating effect on the metabolic activity of neutrophils, depending on TPP dose. TPP administered at a dose of 0.5 mg/kg potentiates the stimulating effect of pyrogen on the percent of NBT-positive neutrophils. A tenfold increase of TPP dose (5 mg/kg) reduces the stimulating effect of LPS and a hundredfold increase (50 mg/kg) leads to total inhibition of LPS-induced changes.

The influence of long-term administration of Tolpa Peat Preparation on immune reactivity in mice. I. Morphological changes in the thymus.

In experiment I BALB/c 200 mice were given in drinking water the TPP (Tolpa Peat Preparation) in daily doses of 1, 10 and 50 mg/kg over the period of 3, 5, 7, 9 and 12 weeks. In experiment II before the administration of TPP (as in experiment I) mice were immunized with a single dose i.p. administration of 0.2 cm3 of a 10% suspension of sheep erythrocytes (SRBC), i.e. 4 x 10(8) cells. Histopathological and ultrastructural studies have shown that TPP in all three doses causes morphological changes characteristic of thymus activity stimulation. However, the doses of 10 and 50 mg/kg administered longer than 7 weeks caused retrograde changes that did not occur after administration of 1 mg/kg of TPP. Morphological changes in the thymus of immunized and non-immunized mice simultaneously receiving TPP were similar.

The influence of long-term administration of Tolpa Peat Preparation on immune reactivity in mice. II. The effect of intermittent TPP administration on the morphological picture of lymphatic organs.

The studies were conducted on 200 Balb/c mice (inbred strain), aged 8 weeks. The mice were administered Tolpa Peat Preparation (TPP) in drinking water (10 or 50 mg/kg/day) for seven weeks (experiment I). Two lobes of the thymus, the spleen and the axillary and mesenteric lymph nodes of mice were taken for histological examinations after 3, 5 and 7 weeks of continuous TPP treatment and also 12 and 16 weeks from the beginning of the treatment. In experiment II, TPP was administered daily at the same doses for 3 weeks, and intermittently for 9 consecutive weeks; a week interval followed each seven-day cycle. The lymphatic organs of mice were taken for histological examinations after 3, 5, 7, 9 and 12 weeks of TPP treatment. It was found that daily administration of TPP (as described above) to mice for 7 weeks (10 mg/kg) induced a marked stimulation of the lymphatic organs (in the first weeks of TPP treatment) and resulted in retrograde changes (depletion of thymocytes and lymphocytes) in the lymphatic structures when TPP administration was prolonged (4-7 weeks). The morphological changes due to TPP administered at the dose of 50 mg/kg were less pronounced in the organs examined. The retrograde changes in the lymphatic structures disappeared 9 weeks after TPP treatment had been stopped. Similarly, the changes showing stimulation of the lymphatic organs were maintained throughout the entire period of 9 weeks.(ABSTRACT TRUNCATED AT 250 WORDS)

[Successful prevention of adhesions using peat and humic acids]. / Erfolgreiche Adhäsionsprophylaxe durch Anwendung von Moor und Huminsäuren.

In order to verify the adhesion preventing capability of peat and peat components, 180 female rats were subjected to therapeutic bathing after standardised lesions had been placed on both uterine horns and the peritoneum of the anterior abdominal wall. From the 3rd and 7th day after surgery, respectively, randomized groups of animals consisting of 20 animals each were bathed in tap water, pure fresh peat, peat solution after pressing, centrifugation and filtration, and a solution of humic acids extracted from peat, all at the same temperature. One week after bathing for three weeks, the rats were relaparotomized, and quality and degree of the adhesions found were documented. Significant less and minor (p less than 0.001) adhesions were found in animals bathed in humic acid solution compared to the animals which had not been bathed at all. Peat solution and fresh peat reduced the formation of adhesions significantly, too, while warm water baths did not show any antiadhesive effect. Our results suggest humic acids to be the most effective component of peat with regard to the prevention of adhesions.

[The content of free amino acids in the tissues of broiler chicks administered sodium humate in the ration]. / Soderzhanie svobodnykh aminokilsot v tkaniakh tsypliat-broilerov pri vvedenii v ratsion gumata natriia.

Natrium humate introduction into ration of broilers activates the synthetic phase of protein exchange. The increase of protein amount in blood serum and chicken tissues, the pool decrease of free amino acids in blood and its simultaneous growth in muscles, increase of proteolysis level, the change in activity of peptide-hydrolase testify to this. In muscles the quantity of free amino acids ensuring the reamination increases considerably.
