The micropuncture evidence relating to the location and the mechanism for concentration and dilution of the urine is reviewed. As required by the countercurrent hypothesis for urine concentration, these data demonstrate that in the presence of antidiuretic hormone, the tubular urine is first concentrated in the descending limb of the loop of Henle and then diluted in the ascending limb of the l...

BACKGROUND Convective dialysis strategies are superior in the removal of protein-bound uraemic retention solutes. Mid-dilution and mixed-dilution haemodiafiltration (HDF), both combining pre-dilution and post-dilution, are promising options to further improve removal capacity and have been shown of additional benefit for large middle molecules. In this study, we compared the removal of small wa...
• .All thennal methods for the study of the circulation depend upon the induction of a change in the heat content of! the blood stream. As a result of the change, a particular time-dependent spatial distribution of temperature is developed in the blood according to the manner in which the change is brought about and as a function of the prevailing pattern of blood flow. In a general sense, any ...

OBJECTIVES To compare the agreement between microbroth dilution and agar dilution for antimicrobial susceptibility testing of Campylobacter jejuni. METHODS Utilizing commercially prepared antimicrobial panels, microbroth dilution was compared with agar dilution for determining antimicrobial susceptibility in C. jejuni isolates. To assess the performance of both techniques for ampicillin, 190 ...
during the past decade, natural plant products as environmentally safe option have received attention for controlling phytopathogenic diseases. investigation of plants containing natural antimicrobial metabolites for plant protection has been recognized as a desirable method of disease control. the fungus fusarium oxysporum causes diseases such as root rot, damping off and fusarium wilt and it ...
objective: this study designed to test the antibacterial potency of enrofloxacin (enr) and essential oils from zataria multiflora boiss (zeo) and trachyspermum copticum (teo)on aeromonas hydrophila. material and methods: the antibacterial potency of test compounds was determined by several methods including the inhibition zone diameter determination, microbroth dilution method and colorimetric ...
helicobacter pylori is the causative agent of gastritis and peptic ulcer disease. eradication of h. pylori is hard to achieve and often require multiple antibiotics regimens. these regimens are quite expensive and have substantial side effects. licorice is a traditional drug which is frequently used for gastric discomforts in iran. the susceptibility of h. pylori to the extract of licorice has ...
