Hyperacidity causes gastric injury, and in severe situations, ulcer could develop. The growth factors known as the basic fibroblast growth factor (bFGF) and the epidermal growth factor (EGF) have been recognized to promote ulcer healing. Fucoidan is extracted from a brown seaweed of Okinawa called Mozuku or Cladosiphon okamuranus. Fucoidan is effective for the healing of gastric ulcers by inducing epithelial cells to produce growth factors. The aim of this study is to explore the efficacy of fucoidan in patient who suffered by gastric ulcer. A randomized control trial double blind was conducted to 33 eligible samples. By using four-blocks random samples were divided into fucoidan and placebo groups. 100 mg of fucoidan was given to the fucoidan group and 100 mg of glucose was given to the placebo group. Due to ethical reasons, for both groups were given a proton pump inhibitor. There was no difference in the age category between the fucoidan group (mean: 46.23 ± 14.8 years) and the placebo group (mean: 46.18 ± 18.4 years) (p: 0.28). There was also no difference in sex between the fucoidan group (female: 10/33; male 7/33) and the placebo group (female: 7/33; male: 9/33); p: 0.38. According to the SAKITA and MIWA criterias 32 patients fulfilled A1 which indicate active severe ulcer, and 1 patient fulfilled A2 which indicate active moderate ulcer. Most of the ulcers were gastric ulcer. There was a significant improvement of the grade of ulcer in fucoidan group (94%) (16/17) compared to placebo group (37.5%) (6/16,p: 0.005). There was a significant reduction of abdominal pain after 5 days in the fucoidan group, compared to the placebo group (p: 0.04). Vomiting tends to decrease in day 6 of the fucoidan group however its proportion is similar with that of the placebo group (p: 0.9). Fucoidan is effective for ulcer healing and reducing ulcer symptoms. Key words : fucoidan, gastric ulcer, anti-peptic activity

The asparagus beetle, Crioceris asparagi L., is a major pest of asparagus in the United States. Commercial growers typically apply a foliar insecticide in the spring to kill adults before they can oviposit on asparagus spears. However, very few new insecticides have been registered on the crop in the last twenty years, and many chemicals have lost their registrations due to enactment of the Food Quality Protection Act. Laboratory and field experiments were conducted to evaluate the efficacy of a novel neonicotinoid insecticide, acetamiprid, to control all life stages of the asparagus beetle. Laboratory toxicity assays revealed that acetamiprid is highly toxic to asparagus beetle eggs and larvae. LC₅₀ levels were 8.95 mg ai/liter for eggs and 0.012 mg ai/liter for larvae. Field efficacy trials in Virginia showed that acetamiprid applied at 0.112 kg ai/ha significantly reduced the numbers of asparagus beetle adults, eggs, and larvae on asparagus equal to or greater than that of the insecticide standard, methomyl. Acetamiprid also provided excellent control of aphids on spears, equal to or greater than that of methomyl.

Death of the apical shoot and subsequent compensatory growth from previously inhibited axillary buds is a possible result of POST weed control practices. The objective of this research was to determine the efficacy of glyphosate and lactofen on ivyleaf morningglory, common waterhemp, and giant ragweed during mechanically stimulated compensatory growth. Plants were grown in the greenhouse to a height (or lateral growth) of 15 cm; at which time, the apical shoots were removed by cutting just above the cotyledonary node. Plants were allowed to regrow to 15 cm and treated with lactofen or glyphosate. Herbicide treatments were also applied to intact plants that were 15 cm in height for comparison. Weed response to herbicides during mechanically stimulated compensatory growth varied by weed species and herbicide. Giant ragweed under compensatory growth was less sensitive to both glyphosate and lactofen compared with intact plants. Comparison of GR₅₀ (the herbicide dose that reduced dry weight by 50%) values indicated that ivyleaf morningglory under compensatory growth was 1.5 times more sensitive to glyphosate than intact plants. Conversely, previously injured ivyleaf morningglory plants were less sensitive to lactofen than intact plants. The GR₅₀ for glyphosate applied to intact common waterhemp plants and plants under compensatory growth was similar. However, common waterhemp plants under compensatory growth were more sensitive to lactofen at the three lowest rates evaluated compared with intact plants. In summary, the efficacy of foliar herbicides applied to weeds that exhibit compensatory growth may be different from weeds under a normal growth state.Nomenclature: Glyphosate; lactofen; common waterhemp, Amaranthus rudis Sauer AMATA; giant ragweed, Ambrosia trifida L.

Greenhouse studies were conducted to determine the effect of 1-aminomethanamide dihydrogen tetraoxosulfate (AMADS) as a spray adjuvant on the efficacy of three different glyphosate formulations, the isopropylamine salt (glyphosate-IPA), potassium salt (glyphosate-K), and the acid of glyphosate dissolved in AMADS (glyphosate-A). All formulations were tested at multiple rates with and without AMADS (2%% v/v) on greenhouse-grown corn, and growth inhibition was determined by measuring the elongation of the newest emerging leaf between 1 and 7 d after treatment. AMADS increased the efficacy of all three glyphosate formulations by threefold to fourfold. The IC₅₀ values for glyphosate-IPA, glyphosate-K, and glyphosate-A without AMADS on corn were 77, 54, and 53 g ae/ha, respectively; and with AMADS the values were 20, 18, and 21 g/ha, respectively. AMADS was more effective than ammonium sulfate (2%% w/v) in overcoming the antagonism of hard water (200 parts per million Ca⁺⁺²) on glyphosate-K efficacy on corn. The rainfastness of glyphosate-IPA, glyphosate-A, and glyphosate-K was improved with AMADS.Nomenclature: Glyphosate; corn, Zea mays L. ‘‘Triumph 1416’’.Additional index words: Ammonium sulfate, rainfastness, surfactant.Abbreviations: AMS, ammonium sulfate; DAT, days after treatment; glyphosate-TMS, formulated trimethylsulfonium salt of glyphosate; HAT, hours after treatment; IC₅₀, concentration that inhibits growth by 50%%; NIS, nonionic surfactant.

As the Selenium is known to be growth promoter in sheep and cattle, the efficacy of selenium has been tested in silkworm Bombyx mori L. The V instar larvae were fed with lethal and sub-lethal doses of selenium treated leaves. The larvae fed with lethal dose showed a significant decrease in growth and Cocoon commercial characters. The treatment with sub lethal dose exhibited a significant increase in the growth of the silkworm. Correspondingly, the cocoon commercial characters on exposure to the lethal dose showed significant decrease and sub lethal dose showed a significant increase.

Two different sets of bioassays were used to test different forms of nitrogen for their effect on compost-induced disease suppressiveness. In the two systems squash served as host for two pathogenic soil - borne fungi, Fusarium and Rhizoctonia. Results from both bioassay systems confirmed that ammonium nitrogen (NH4-N) markedly improved natural disease suppression properties of composted biowastes

<p>Abstract</p> <p>Background</p> <p>Recently, a propanol-based hand rub has been described to exceed the efficacy requirements of the European standard EN 12791 in only 1.5 min significantly. But the effect of a 1 min preceding hand wash and the effect of one additional minute for evaporation of the alcohol after its application on the efficacy after a 1.5 min application time has never been studied.</p> <p>Methods</p> <p>We have investigated a propanol-based hand rub (Sterillium^®, based on 45% propan-2-ol, 30% propan-1-ol and 0.2% mecetronium etilsulfate) in three variations: with (A) and without (B) a 1 min hand wash before the disinfection of 1.5 min with immediate sampling after the disinfection; and (C) without a hand wash before the disinfection but with sampling 1 min after the disinfection. The efficacy of the three variations was compared to the reference treatment of EN 12791. All experiments were performed in a Latin-square design with 20 volunteers. Pre- and post-values (immediate and after 3 hr) were obtained according to EN 12791.</p> <p>Results</p> <p>The 3 min reference disinfection reduced resident hand bacteria on average by 1.8 log₁₀steps (immediate effect) and 1.4 log₁₀-steps (sustained effect) respectively. Method A was equally effective as the reference (immediate efficacy: 1.5 log₁₀-steps; sustained efficacy: 1.6 log₁₀-steps). Method B seemed to be more effective (immediate efficacy: 2.3 log₁₀-steps; sustained efficacy: 1.7 log₁₀-steps). Method C revealed the best efficacy (immediate efficacy: 2.3 log₁₀-steps; sustained efficacy: 2.0 log₁₀-steps). A comparison of all three treatment variations and the reference treatment revealed a significant difference for the immediate efficacy (p = 0.026; Friedman test), but not for the sustained efficacy (p = 0.430). A post-hoc-test for the immediate efficacy indicated a significant difference between methods A and C (p < 0.05; Wilcoxon-Wilcox test). Hence, none of the treatment variations was significantly less effective than the reference treatment.</p> <p>Conclusion</p> <p>An application of the propanol-based hand rub for 1.5 min after 1 min hand wash fulfills the efficacy requirements of EN 12791. The efficacy can be improved to some extent by omitting the preceding hand wash and by awaiting the evaporation of the alcohol which is clinical practice anyway. The preceding hand wash has the most negative effect on the immediate effect. Based on our data hands should not be routinely washed before the disinfection period unless there is a good reason for it such as visible soiling.</p>

The efficacy of Quassia extract with a standardized content of Quassin was proved in various field trials in different regions during three years. The amount of Quassin of 6 g/ha/m tree height will be recommended to practice. It is not important to have a contact effect on the eggs. The larvae must feed on the product before they enter the fruit. There is a very good efficacy on primaray infestation. Furthermore, there is even an efficacy on secondary infestation. Thus, even if due to difficult conditions during application or not optimal termination of the treatment the efficacy on the primary infestation is not entirely sufficient, the secondary infestation will be controlled better.

The efficacy of water, chlorinated water (100 ppm), peracetic acid solution (0.05%), and commercial citric acid-based produce wash (0.25%) to reduce the population of Listeria monocytogenes on precut lettuce was tested. Samples were inoculated with a mixture of equal amounts of five L. monocytogenes strains at a level of 4.7 log CFU/g, and analyzed on the day of washing and after 3 and 6 days of storage at 6 degrees C. Sanitizer reduced the number of L. monocytogenes at maximum 1.7 log CFU/g and number of L. monocytogenes reached the inoculation level during 6 days of storage. Thus, disinfectants do not eliminate L. monocytogenes on precut lettuce and cannot be solely relied on in producing precut lettuce safely. The inoculated L. monocytogenes strains were recovered at different rates after 6 days of storage; one of these strains was not recovered at all. Thus, strain-specific differences exist in the ability of L. monocytogenes to survive the washing treatments of the lettuce.
