  • This study was conducted to obtain the basic information on the burley tobacco (Nicotiana tabacum L.) curing methods. The effects of the three kinds of curing methods on the dry weight losses during curing, chemical contents and physical properties of cured leaves, and organoleptic and smoking qualities were observed. The dry weight losses during curing was the highest in the stalk curing, and the lowest in the conventional priming. The longer the curing periods was, the more the loss of dry weight. The percent of the excessive dried leaves was high and the price per kilogram was low in the conventional priming. The chemical contents and the physical properties of the cured leaves in the conventional priming were similar to those of yellowing or browning stage of curing. But, the chemical contents and the physical properties of the cured leaves in the stalk curing were comparable to those of the air curing. The smoking quality was the best in the stalk curing.

  • The diagnosis of canine diabetes mellitus is generally made by measuring serum fructosamine levels. The Rosental's end points Tas and El Din's kinetic, and Johnson and colleagues'kinetic techiniques were compared for the measuring serum fructosamine levels. In the Rosental's end point methods within-run and between-run coefficient of variability (CV) were 2.4-3.5% and 6.8-8.5%, respectively, and in the Tas and El Din's kinetic method, within-run and between-run CV were 1.3-3.0% and 3.4-3.9%, respectively. In the Johnson and colleagues'kinetic methods within-run and between-run CV were 0-1.8% and 3.1-6.8%1 ruts- pectively. Hyperlipidemia induced by oral administration of 3 ml of corn oil per kilogram body weight did not affect serum fructosamine concentration significantly in the Johnson and colleagues' kinetic method Johnson and colleagues'kinetic method is most reliable and consistant on the basis of comparison study.

  • Four out of 15 dogs were successfully induced diabetes mellitus with intravenous iqiection of 30 mg of streptozotgin and 50 mg of alloxan monohydrate per kilogram body weight and maintained more than 9 weeks without iqiection of insulin or oral hypoglycemic sgent Histopathologicallyi these four dogs have typical diabetic lesions such as degeneration and vacuolation of pancreatic islet cells, and fatty change of liver at necropsy in the end of study. Serum glucose level increased dramatically at 24 hours post-injection but serum fructosamine level increased gradually and reached plateau at 31-41 days post-injection of streptozotocin and alloxan. Serum fructosamine concert%lion correlated very well with serum glucose concentration of preceding 4-7 weeks in experimentally induced diabetic dogs. Our data suggest that serum fructosamine reflects mean glucose concentration of preceding 4-7 weeks in experimentally induced diabetic dogs.

  • This study was carried out to present the measures for the stable organic rice production, farm income increase and consumption revitalization and so on by analyzing economic effects of the organic rice production complex and farmers by cultivation type. The farmers received prices of organic rice and Life and Environment Agriculture (LEA) were 2,965 won and 2,014 won per kilogram, respectively. Finally, the results of the productivity analysis show that LEA produces about 11% lower crop yield compared with the conventional farming. Meanwhile, the profitabilities of the organic farming per 10a were about 15% higher than the conventional farming. But, LEA per 10a was individually 23% lower then the conventional farming.

  • This study was carried out to investigate the changes of dehydration process and quality of cured leaves with crushed midribs and cut of the yellowed leaves during drying stage of flue-cured tobacco. The crushed midribs of yellowed leaf dried out before raising the highest temperature of midrib drying stage and reduced the curing time by about 20 hours. However, the cut of yellowed leaf was not affected the curing time and dehydration process during drying stage of flue-curing due to a problem with the cut leaves packing excessively in the curing container. The cured weight yield was increased with crushed midrib and cut leaves, and nicotine and sugar contents of cured leaves and quality in terms of dollars per kilogram were decreased with crushed midrib and cut leaves.

  • Many losses in domestic animals have bern reported in this country, since sodium monofluoroacetate (Compound 1080) was used as a rodenticide. Lesions described inclubed multiple petechiae in epi- and endocardium, lung and intestinal mucosa, or superficial necrosis of the gastric mucosa. In this studies as to the poisoning 7 rabbits were administered 0.6mg (Group I), 0.4mg (Group II), and 0.3mg (Group III) of sodium monofluoroacetate per kilogram of body weight. and the results obtained were as follows: In addition to the changes mentioned above fatty degeneration in central parts of hepatic lobule or nut meg liver, haemorrhagic feci in cerebral cortex and leptomeninges and fatty degeneration in kidney and cardiac muscles were found.

  • Plant species have shown the capability to absorb U into the biomass. Norman(l952) even suggested that uranyl ion acts as an accessory microelement in growth of Lemna and flax roots. The plants, termed metal hyperaccumulators, can extract and accumulate more than 1000-10,000mg heavy metal per kilogram of dry weight of plants (0.1-1%). The most vital main factors influencing the ability and efficiency of phytoremediation is the ability of the plant to uptake the metals from soil before the accumulation mechanism happens in the plant tissue.

  • In order to know the kinds of liver function tests which are applicable to the hepatotoxicity experiment in Korean black goats, 0.3ml of carbon tetrachloride per kilogram body weight was injected intraruminally in 6 Korean black goats and 8 liver function tests were performed sequentially during the 14-day experimental course. Serum total bilirubin concentration, serum alkaline phosphatase activity and BUN concentrotion were suggested not to be applicable to the hepatotoxicity experiment in Korean black goats as they were not altered significantly during the 14-day experimental course. Indocyanine green T 1/2, Serum AST, SDH, gamma-GTP, and OCT activities were suggested to be applicable as sensitive indicators to the hepatotoxicity experiment in Korean black goats.

  • A certified reference material (CRM) for the analysis of nutrient elements in an edible mushroom (Ganoderma lyceum) powder has been developed (KRISS CRM 108-10-011). The mass fractions of calcium (Ca), iron (Fe), and zinc (Zn) were measured by isotope dilution inductively coupled plasma mass spectrometry (ID ICP/MS). To dissolve the fungi cell wall of mushroom consisted of chitin fibers, sample preparation method by single reaction chamber type microwave-assisted acid digestion with acid mixtures was optimized. The mean measurement results obtained from 12 sample bottles were used to assign as the certified values for the CRM and the between-bottle homogeneities were evaluated from the relative standard deviations. The certified values were metrologically traceable to the definition of the kilogram in the International System of Units (SI). This CRM is expected to be used for validation of analytical methods or quality control of measurement results in analytical laboratories when they determine the mass fractions of elements in mushroom or other similar samples.
