In 2007, pet food contaminated with melamine caused hundreds of dogs and cats to develop renal failure all over the world. In 2008, over 294,000 infants consumed infant formula and developed kidney stones in China. Further investigation revealed that fish feed also contained melamine; this raised concerns about melamine residues in edible fish tissues, which could have caused the urinary tract stone epidemic. In Korea, catfish fed with assorted feed that included cuttlefish organs that contained melamine developed whitening syndrome and fell dead in some populations in 2008. This event raised suspicions about the toxicity of melamine and all feeds containing melamine were immediately recalled. In this study, we investigated the rates of melamine accumulation and depletion in muscle and viscera of catfish to propose proper withdrawal periods. One group of catfish was fed a commercially available diet that contained 30, 100 and 300 mg melamine per kg diet for 14 days. To investigate residual melamine contents in muscle and viscera, other experimental groups were fed a melamine free diet after being fed melamine for 7 days. The residual amount of melamine was analyzed by LC-MS/MS. The melamine concentration in muscle was estimated to be 3.7 mg/kg after 6 days of feeding with a diet containing 300 mg melamine/kg. After 2 days of culture with a melamine free diet, the residual melamine was depleted and the concentration had decreased from 1.15 mg/kg to 0.19 mg/kg in the muscle of catfish fed a diet containing 300 mg melamine/kg for 7 days. The residual amount of melamine was reduced to 0.03 mg/kg in muscle after 7 days of culture with a melamine free diet and was undetectable after a prolonged culture period of 14 days. Catfish tend to excrete melamine rapidly after oral administration and changes in body color were not observed during the short dosing period.

세대 및 특징이 다른 쇄석기종의 치료효과와 안전성을 비교하기 위해 2세대 Northgate사의 SD-3 쇄석기와 3세대 Storz사의 Modulith SLX 쇄석기로 체외충격과 쇄석술을 시행한 단일요로결석 환자 2000례를 분석한 결과, 치료효과를 판정해 볼 수 있는 요로결석의 위치 및 크기에 따른 성공률과 재시행률에서는 큰 차이가 없는 것으로 분석되어, 제 3세대 쇄석기인 Modulith SLX와 Northgate SD-3의 치료효과는 비슷한 것으로 나타났다. 그리고, 두 쇄석기종 모두에서 심각한 합병증의 발생은 없었으나, Northgate SD-3에서 Modulith SLX 보다 합병증으로 인한 입원치료를 받은 환자의 수가 많았다. 이상으로 두 기종 사이의 치료효과에는 큰 차이가 없고, Modulith SLX률 이용한 체외충격파쇄석술이 조금 더 안전한 것으로 나타났지만 두 기종의 장단점을 서로 보완하여 사용한다면 더욱 효과적인 치료방법이 될 것으로 생각된다.

목적 : 소아에서 전신 질환 없이 단독 혈뇨를 보이는 환이중에서 특발성 고칼슘뇨증의 빈도, 이의 임상적인 의의 및 장기적인 예후를 알아보고자 본 조사를 시행하였다. 방법 : 대상 환아는 전신 질환 없이 단독혈뇨를 주소로 경북대학병원 소아과에 입원한 150례로 하였으며 고칼슘뇨증은 통상적인 식사를 취하는 동안 24시간 요칼슘배설이 4mg/kg 이상인 경우로 하였고 입원후 경구칼슘 부하검사를 시행하여 흡수형 흑은 신성으로 구분하였다. 모든 환아에서 입원시 및 추적 관찰 기간중 1년간격으로 초음파를 시행하여 신결석 유무를 확인하였고 또한 Dipstick을 이용하여 혈뇨 소실 여부를 추적 관찰하였다. 결과 : 대상 환아 150례중 44례 (29%)가 특발성 고칼슘뇨증으로 진단되었으며 정상 칼슘 배설군에 비해 여아보다 남아 (9:35)가 많았고 혈뇨 양상은 육안적 혈뇨가 현미경적 혈뇨 (37:7)보다 많았다 (P<0.05). 경구 칼슘 부하검사로서는 신성이 29례, 흡수형이 8례였으며 7례에서는 형을 결정할 수 없었다. 세 형간의 24시간 요중 칼슘배설량 및 각종 검사상 차이점은 발견 할 수 없었다. 3례에서 시행한 신조직검사는 모두 정상 소견이었다. 고칼슘뇨증 환아에서의 신결석의 발생은 4례 (입원시 2졔 및 추적 관찰 기간 $1{\sim}2$년에 2례)로서 10%의 빈도를 보였으며 신결석이 발생한 군은 발생하지 않은 군에 비하여 연령이 낮았으며 ($3.7{\pm}2.7\;vs\;7.2{\pm}2.9$ yr) 여아가 남아보다 많았다 (3:1 vs 6:34) (P<0.05). 24시간 요칼슘배설량 및 칼슘 부하검사에 의한 유형에 따른 차이는 없었다. 혈뇨의 소실은 추적 관찰 기간 $1{\sim}2,\;2{\sim}4,\;4{\sim}6$ 및 $6{\sim}8$년에 각각 56, 50, 66및 75%의 환아에서 혈뇨가 소실되었다. 결론 : 특발성 고칼슘뇨증은 소아의 혈뇨의 원인으로서 중요한 위치를 차지함을 알 수 있었으며 그러므로 반복성 혹은 육안적 혈뇨 환아에 대해서는 요중 칼슘 배설량 측정이 필수적인 검사로 생각된다. 또한 신장 결석 발생의 조기 진단을 위하여 정기적인 신초음파 검사가 필요하다 하겠다. 그러나 경구 칼슘 부하검사에 의한 신성과 흡수형의 구분은 임상적으로 큰 의의가 없는 것으로 생각되며 이에 관해서는 추후 더 많은 연구가 필요할 것으로 생각된다.

Engineers have developed new instruments that aid in diagnosis and therapy Ultrasonic imaging has provided a nondamaging method of imaging internal organs. A complex transducer emits ultrasonic waves at many angles and reconstructs a map of internal anatomy and also velocities of blood in vessels. Fast computed tomography permits reconstruction of the 3-dimensional anatomy and perfusion of the heart at 20-Hz rates. Positron emission tomography uses certain isotopes that produce positrons that react with electrons to simultaneously emit two gamma rays in opposite directions. It locates the region of origin by using a ring of discrete scintillation detectors, each in electronic coincidence with an opposing detector. In magnetic resonance imaging, the patient is placed in a very strong magnetic field. The precessing of the hydrogen atoms is perturbed by an interrogating field to yield two-dimensional images of soft tissue having exceptional clarity. As an alternative to radiology image processing, film archiving, and retrieval, picture archiving and communication systems (PACS) are being implemented. Images from computed radiography, magnetic resonance imaging (MRI), nuclear medicine, and ultrasound are digitized, transmitted, and stored in computers for retrieval at distributed work stations. In electrical impedance tomography, electrodes are placed around the thorax. 50-kHz current is injected between two electrodes and voltages are measured on all other electrodes. A computer processes the data to yield an image of the resistivity of a 2-dimensional slice of the thorax. During fetal monitoring, a corkscrew electrode is screwed into the fetal scalp to measure the fetal electrocardiogram. Correlations with uterine contractions yield information on the status of the fetus during delivery To measure cardiac output by thermodilution, cold saline is injected into the right atrium. A thermistor in the right pulmonary artery yields temperature measurements, from which we can calculate cardiac output. In impedance cardiography, we measure the changes in electrical impedance as the heart ejects blood into the arteries. Motion artifacts are large, so signal averaging is useful during monitoring. An intraarterial blood gas monitoring system permits monitoring in real time. Light is sent down optical fibers inserted into the radial artery, where it is absorbed by dyes, which reemit the light at a different wavelength. The emitted light travels up optical fibers where an external instrument determines O2, CO2, and pH. Therapeutic devices include the electrosurgical unit. A high-frequency electric arc is drawn between the knife and the tissue. The arc cuts and the heat coagulates, thus preventing blood loss. Hyperthermia has demonstrated antitumor effects in patients in whom all conventional modes of therapy have failed. Methods of raising tumor temperature include focused ultrasound, radio-frequency power through needles, or microwaves. When the heart stops pumping, we use the defibrillator to restore normal pumping. A brief, high-current pulse through the heart synchronizes all cardiac fibers to restore normal rhythm. When the cardiac rhythm is too slow, we implant the cardiac pacemaker. An electrode within the heart stimulates the cardiac muscle to contract at the normal rate. When the cardiac valves are narrowed or leak, we implant an artificial valve. Silicone rubber and Teflon are used for biocompatibility. Artificial hearts powered by pneumatic hoses have been implanted in humans. However, the quality of life gradually degrades, and death ensues. When kidney stones develop, lithotripsy is used. A spark creates a pressure wave, which is focused on the stone and fragments it. The pieces pass out normally. When kidneys fail, the blood is cleansed during hemodialysis. Urea passes through a porous membrane to a dialysate bath to lower its concentration in the blood. The blind are able to read by scanning the Optacon with their fingertips. A camera scans letters and converts them to an array of vibrating pins. The deaf are able to hear using a cochlear implant. A microphone detects sound and divides it into frequency bands. 22 electrodes within the cochlea stimulate the acoustic the acoustic nerve to provide sound patterns. For those who have lost muscle function in the limbs, researchers are implanting electrodes to stimulate the muscle. Sensors in the legs and arms feed back signals to a computer that coordinates the stimulators to provide limb motion. For those with high spinal cord injury, a puff and sip switch can control a computer and permit the disabled person operate the computer and communicate with the outside world.
