On July 4, 1954 Sam Sheppard called police to report that his wife Marilynn was dead in the bedroom. He said the night before, his wife had gone upstairs to bed while he was asleep on the couch. When he went upstairs, he saw his wife covered in blood. He heard a noise and ran downstairs chasing after a 6’3’’ bushy haired man. The two struggled and Dr. Sheppard was choked unconscious. When police arrived, Marilynn was found with 35 wounds to the head and blood drenched the walls, door, and bed. Her face was almost unrecognizable. Sheppard served 10 years in prison before the US Supreme court rules that the trial had been tainted. The evidence was reexamined. Blood spatters and blood drops provided some of the most compelling evidence. Dr. Paul Kirk, an expert in blood analysis, determined the killer could not have been Sam because the attack was perpetrated by a left handed person. Dr. Sheppard was right handed.. .. The presence of color gives the cells significant contrast so are much more visible. . Different stains have different affinities for different organisms, or different parts of . organisms. They are used to differentiate different types of organisms or to view specific parts of organisms. Basic vs. acidic dyes. Differential Stain. Primary stain (stains all cells on slide). Decolorizing step (removes stain from certain types of cells). Counterstain (stains the decolorized cells). Differentiate bacteria into two large groups (the Gram Positive and the Gram negative).. Gram status is important in medicine; the presence or absence of a cell wall will change the bacterium's susceptibility to some antibiotics. تقنية الأجهزة . الكيموحيوية. .
