This article demonstrates the step by step technique to remove the lung and inflate it with fixative in order to achieve optimal fixation of the tissue within 24 hours. High-Performance Liquid Chromatography (HPLC) analysis has revealed the presence of flavonoids such as naringenin, eriodictyol, apigenin, and luteolin [16]. Risk factors for gastric ulcers include long-term use of steroidal and nonsteroidal anti-inflammatory drugs (NSAIDs), Helicobacter pylori infection, smoking, and alcohol intake [1, 3]. The histometrical analysis indicated that the estimated percentages of the additive bone, especially in kabab loghme, were not significantly different from the real percentages. The earliest evidence of magnify-, ing glass forming a magnified image dates back to 1021 when the, physicist Ibn al-Haytham (965–1039) published the “Book of, Optics.” The name “microscope” was crafted by the German, botanist Johann Faber (1574–1629). Two groups () of male Sprague-Dawley rats (8-10 weeks old, 180-220 g) were acclimatized for 15 days before the commencement of the test. 2.6.3. The “Swiss roll”: a simple technique for histo-, H., and Creasy, D.M. A correct angle should be set to, avoid compression in cut sections and to reduce friction as, the knife passes through the block. A number of histologic stains are available that are routinely used to visualize fungi in tissue sections. Also, the plant showed good antioxidant activity comparable to gallic acid. Wax sections provide adequate quality for evaluating screening studies.

Additionally, because conventional Davidson's fixative (DF) is used routinely for optimum fixation of eyes, preservation of ocular histomorphology by DF and mDF was compared. Grading severity may be based on the proportion of tubules affected or on the proportion of germ cells affected or lost. The Griess-Ilosvay reagent utilizes 0.1% () naphthyl ethylenediamine dihydrochloride. 4.2 Procedure 4.2.1 Safety showers 1. A graph of the percentage of inhibition against concentration in μg/mL was plotted from which IC50 values were calculated. After fixation, tissue samples need to be properly trimmed to reach, the adequate size and orientation of the tissue. If not, put the mold back, onto the warm work surface until the whole paraffin liquefies, Immediately place the base of the original cassette on top, of the mold. Group I rats were treated with 10 ml/kg/day of Set the section thickness around 15 microns. This also allows tissue section storage for several, years.
