  • Recent social and medical developments have significantly changed both the concept of death and the criteria for its pronouncement. Instead of considering. the heart as central to the determination for death, it is now prevalent to use death of the brain as adequate for death regardless of cardiac function in most western countries. But the brain death theory is not yet legally accepted despite growing public interest in our country due mainly to customary and moral reasons. Subsequently heart transplantation, which necessitates the concept of brain death, still remains a possible surgical entity in the future. As a part of endeavor the evaluate social atmosphere for the legal acceptance of the concept of brain death and the availability of potential heart donors, a four-page questionnaire on brain death and cardiac transplantation was given to the sophomore students of a medical college in Seoul[n=116, group I] and their family members[n=83, group II ]. The groups were chosen under the assumptions that they lacked sophisticated medical knowledge but had general medical interest so reliable data could be obtained. The majority of respondents in both group I and II thought that they knew the concept of brain death[group I 99.1%, group II 93.3%] and the definition of heart transplantation[group I 94%, group II 67.6%] at least to some extent, but only a small proportion of them was proven to have correct knowledge: brain death[74.4%, group II 39. 8%], heart transplantation[group I 31.9%, group II 30.1%]. Most respondents answered in the affirmative for the legal approval of brain death[group I 87.8%, group Il 97.9%]. The possibility of medical usage of brain dead organs was the biggest reason for brain death[group I 52.9%, group Il 47.9%]. Ninety-one percent of group I and 89.1 percent of group II responded that they were willing to give permission for donating the heart of brain-dead family members. Fifty-nine percent of group I and 51.9 percent of group II wanted their own heart donated. These results suggest, despite some inherent sampling limitations, that favorable responses to brain death and heart transplantation can be obtained among the general public if they are properly informed.

  • Brain dead (BD) patients remain the largest source of solid organs for transplantation. BD has shown to decrease graft function and survival in rodent models. The aim of this study was to evaluate how brain death affects graft viability in the donor and kidney tolerance to cold preservation as assessed by survival in a canine transplantation. 13 Beagle dogs were used for the study. Brain death was induced by the sudden inflation of a subdural balloon catheter with continuous monitoring of arterial blood pressure and eletroencephalographic activity (n=3). Sixteen hours after conformation of brain death, kidney graft were retrieved (n=6). Non-BD donors served as controls (n=4). All kidneys were flushed with University of Wisconsin (UW) solution and preserved for 24 hours at 4$^{\circ}C$ before transplantation. Recipient survival rates, serum creatinine level were analyzed. Brain death induced the well-known Cushing reaction with a severe increase in blood pressure and tachycardia. Thereafter, cardiac function returned progressively to baseline within 8 hours and remained stable until the end of the experiment. All of dogs in both group transplanted were survived until 7 days (100%), and the kidneys showed functional early rejection at 8.3$\pm$0.5 days and 8.5$\pm$0.5 days after transplantation, in BD and allograft group, respectively. BD kidneys were functionally similar to control kidneys for 7 days after transplantated. Brain death has no deleterious effect on preservation injury and survival of dog kidney transplantation, although it induces changes in hemodynamic parameters. This study reveals that kidneys from BD donors do not exhibit more ischemia reperfusion injury, and support good early function and survival.

  • The smears and tissue sections of organs (liver, lung, kidney, heart, lymph-node, brain) were carried out to compare the detection of parasites in the splenectomized calves artificially infected with B. bigemina and B. argentina, respectively. The results obtained from this experiment were abstracted as follows: 1. In the calves infected with B. argentina the parasites were easily detected by the blood smears and tissue smears but, particularly, the detection of parasites in the kidneys and brain by tissue smears and tissue sections was greater useful. In this experiment, the packing of the parasite-infected red blood cells was found in the capillary vessels of the organs. 2. When the fresh infected-brain was kept at $5^{\circ}C$ refrigerator, Babesia argentina could be detected during 9 days from the brain smears. According to this results, we could do differentiate the parasites from the brain of the dead animal by the doubtful babesiosis in the field. 3. If we use the brain smears and brain sections in order to survey or detect Babesia infections of cattle in Korea, these methods could be worthwhile for the differential diagnosis of B. argentina and B. bigemina.

  • The purpose of this study was necessary to increase certainty of nursing ethical value and recognition of organs donation in the nurses. Multiple programs are consistently need to educate nursing ethical value. The subjects were 222 nurses in a hospital. Data collection was carried out for seventeen days from 14th January 2011, using a structured questionnaire. The data were analyzed using SPSS program. The mean score of nursing ethical value was $3.22{\pm}0.38$ points. The mean score toward organ donation in brain dead donors was $3.34{\pm}0.48$ points. Nursing ethical values almost never had a correlation(r=.160) toward organ donation in brain dead donors.

  • Background: Nonsyndromic craniosynostosis is a relatively common craniofacial anomaly and various techniques were introduced to achieve its operative goals. Authors found that by using smaller bone fragments than that used in conventional cranioplasty, sufficiently rigid bone union and effective regeneration capacity could be achieved with better postoperative outcome, only if their stable fixation was ensured. Methods: Through bicoronal incisional approach, involved synostotic cranial bone together with its surrounding areas were removed. The resected bone flap was split into as many pieces as possible. The extent of this 'multi-split osteotomy' depends on the degree of dysmorphology, expectative volume increment after surgery and probable dead space caused by bony gap between bone segments. Rigid interosseous fixation was performed with variable types of absorbable plate and screw. In all cases, the pre-operational three-dimensional computed tomography (3D CT) was checked and brain CT was taken immediately after the surgery. Also about 12 months after the operation, 3D CT was checked again to see postoperative morphology improvement, bone union, regeneration and intracranial volume change. Results: The bony gaps seen in the immediate postoperative brain CT were all improved as seen in the 3D CT after 12 months from the surgery. No small bone fragment resorption was observed. Brain volume increase was found to be made gradually, leaving no case of remaining epidural dead space. Conclusion: We conclude that it is meaningful in presenting a new possibility to be applied to not only nonsyndromic craniosynostosis but also other reconstructive cranial vault surgeries.

  • Rabies causes the highest mortality of all viral diseases in the world unless the victim has been protected either by active immunization or post-exposure immunoprophylaxis. Infected stray dogs, raccoons, skunks, foxes and bats are the demonstrated carriers of most cases of rabies. It is difficult to diagnose a rabid animal in the field unless characteristic clinical signs are evident. However, this study used a commercial fast check kit comprised of immunochromatographic test (ICT) strips (ICTS) to diagnose rabies infection in clinically suspected samples obtained from a wildebeest. A 10-year old male wildebeest (approximate weight, 150 kg) died at Bangabandhu Sheikh Mujib Safari (BSMS) Park, Cox's Bazar, Bangladesh with a clinical history of severe excitation and abundant oral secretions. A gross pathological examination revealed no specific lesions indicating any fatal diseases. The entire brain was collected within 6 hours of death, and the brain sample was tested using the ICT strips following the manufacturer's directions. The rabies viral antibody was detected within the brain stem and medulla of the brain tissue of the dead wildebeest.

  • The congenital head anomalies are most often used to describe defects in the eyes, mouth, nose, skull, and or brain. The faulty embryogenesis most likely found to be associated with abnormal genetic or epigenetic causes during pregnancy. Eventually it leads to congenital anomalies. Rabbit-headed Lamb (RH) is a disorder in sheep breeding that is characterized by some deformities in the head and the face. A dead -day old- crossbred white Najdi lamb with a deformed face and head was reported to be born in the current case. The external and physical examination revealed a deformed skull and facial region with a unilateral eye, fused mouth, pig-like nose, and patent skull with the brain coming out from left eye orbit. Additionally, the lamb was very skinny with unusual long extremities. This is the first report of this syndrome that describes such deformities in a stillbirth Najdi breed lamb.

  • A 52-year-old man was found dead in the driver's seat of his tank lorry. The tank lorry was used to transport industrial wastewater to a disposal plant; the material was transferred into a storage tank with the help of compressed air. The wastewater contained methylene chloride and 2-chloropyridine. No respiratory protective equipment was used while working under these conditions. The autopsy report showed extensive edema and congestion of the brain, lung, and intraperitoneal organs. The concentrations of methylene chloride in lung and brain were reported at 398 and 67 mg/kg, respectively.
