Split Root

The effects of root infection by Phytophthora cinnamomi on stomatal conductance in Castanea sativa L. saplings were investigated to determine the potential role of root-derived chemical signals. A split-root experiment was carried out, in which inoculation of the pathogen or drought was applied to the root systems in either one or both compartments. At the end of the experiment plant sap extracts were collected and their effects on stomatal conductance were determined by leaf bioassay. Inoculation or drought imposed in both compartments resulted in decreases in stomatal conductance (gs), transpiration rate, soil-to-leaf specific hydraulic conductance, leaf water potential, xylem [ABA] and root biomass, but not in the ratio of root-to-leaf mass in inoculated plants. Conversely, only gs and xylem [ABA] were affected in plants inoculated or droughted in one compartment, and no changes were detectable in leaf water potential and soil-to-leaf specific hydraulic conductance. The leaf bioassay showed that gs in chestnut was sensitive to ABA but not to Phytophthora elicitins. Stomatal conductance was reduced by some sap extracts, both from control and inoculated plants. Our results suggest the involvement of different signals, chemical and hydraulic, in regulating stomatal conductance of chestnut at different stages of stress.

Dextran Solution

The role of vascular volume in regulation of the blood level of antidiuretic hormone (ADH) was investigated utilizing a chemical procedure for extraction, isolation, and concentration of ADH in blood. The antidiuretic material recovered from blood was identified as ADH on the basis of its biological activity and the results of a number of chemical tests. Reduction in extracellular fluid volume by peritoneal lavage with hypertonic solution produced a fourfold increase in the blood titer of ADH within 20 min. Expansion of vascular volume at that time by the intravenous infusion of isotonic dextran solution resulted in a 50% reduction in the blood level of ADH. This reduction was maintained for the 30-min period of observation, although the blood level of ADH rose progressively when the lavage procedure was uninterrupted by infusion of dextran solution. It is concluded that blood volume is an important factor in regulation of blood concentration of ADH.

Healing Second degree burns can be affected by the presence of bacteria. This research reveals the role of honey and MEBO in removing bacterial effects on healing. Pure experimental research method with a completely randomized design (CRD). There were 4 treatments, which were positive, negative, honey and MEBO treatment, each of which was given to rats with second degree burns. Wound healing and other parameters were observed on 7 th, 14th and 21st days. The result was that the administration of honey as an antibacterial drug was very effective and gave healing on the 21st day to white rats. Giving MEBO as an antibacterial drug is very effective and provides healing on the 21st day to white rats. Giving honey is more effective than MEBO as an antibacterial drug and healing burns on 21st day against white rats.

Cholesterol Levels

Cholesterol is an essential substance for the body. The role of cholesterol as material hormones,cell membranare needed by the body. This conditionchanges into a distrubtion if the cholesterollevels in the blood increase. Weight becomes one of this trigger. The consumption of high-fat foodsincrease weight which resulting in the increase of cholesterol cases. The purpose of this study was todetermine the level of correlations between weight and cholesterol levels after being given a high-fatdiet.The study used rats (Rattus norvegicus) sex male, 16 rats with age between 1-2 months. Rats weightrange between 100-150 gr and in healthy conditions. The giving of high-fat diet were in the form ofchicken feed, duck eggs, goat oil, lard and flour for 8 weeks. The data measurement done by scales andmeasuringcholesterol levels through the end of the tail by means of easy touch. The data analysis weredone to understand level of correlation between variables. The presentation of the data used tables. Theresults showed body weight of rats did not change after administration of a high-fat diet. The cholesterolslevels of the subjects were high. Theadministration of high-fat diet from egg yolk dan goat oilcouldincrease the level of cholesterol. There was a correlation between weight and cholesterol levels afterbeing given a high-fat diet (p <0.5). It was needed to repeatthe measurements to determine changes incholesterol levels and other factors that affect thigh blood to cholesterol levels.
