Fetoscopy is a procedure that is carried out on pregnant women with the help of a fetoscope. A fetoscope is a thin and flexible medical apparatus. It carries out an endoscopic pregnancy test. The fetoscope is inserted into the uterus through an incision made in the stomach. An ultra sound is required when carrying out a fetoscopy . It ensures that the doctor can see where the incision is being carried out to avoid harming the baby and also how the fetoscope is moving in the womb. Fetoscopy is used to judge progress of the pregnancy or treat any abnormalities. The Amniocentesis procedure is another procedure that offers information during the prenatal period of the status of the fetus.
The biggest problem was producing enough penicillin. This was hard and expensive to accomplish. Florey and another researcher traveled to the . to talk to chemical manufacturers and ended up in Peoria, Illinois. An agricultural research center there had developed excellent techniques of fermentation, a process needed for penicillin growth. The agriculture of Illinois proved useful, too. The nutrient base for the penicillin grown there was corn (maize), which was not commonly grown in Britain. The penicillin loved it, and yielded almost 500 times as much as it had before. More vigorous and productive strains of the mold were sought, and one of the best came from a rotting canteloupe from a Peoria market!
Recompression is the most effective, though slow, treatment of gas embolism in divers.  Normally this is carried out in a recompression chamber . As pressure increases, the solubility of a gas increases, which reduces bubble size by accelerating absorption of the gas into the surrounding blood and tissues. Additionally, the volumes of the gas bubbles decrease in inverse proportion to the ambient pressure as described by Boyle's law . In the hyperbaric chamber the patient may breathe 100% oxygen, at ambient pressures up to a depth equivalent of 18 msw. Under hyperbaric conditions, oxygen diffuses into the bubbles, displacing the nitrogen from the bubble and into solution in the blood. [ citation needed ] Oxygen bubbles are more easily tolerated.  Diffusion of oxygen into the blood and tissues under hyperbaric conditions supports areas of the body which are deprived of blood flow when arteries are blocked by gas bubbles. This helps to reduce ischemic injury. [ citation needed ] The effects of hyperbaric oxygen also counteract the damage that can occur with reperfusion of previously ischemic areas; this damage is mediated by leukocytes (a type of white blood cell).
