This study focused on the socialist camp's North Korean medical support and its effects on North Korean medical field from liberation to 1958. Except for the Soviet assistance from liberation to the Korean War, existing studies mainly have paid attention to the ‘autonomous’ growth of the North Korean medical field. The studies on the medical support of the Eastern European countries during the Korean War have only focused on one-sided support and neglected the interactions with the North Korean medical field. Failing in utilizing the materials produced in North Korea has led to the omission of detailed circumstances of providing support. Since the review of China's support and the North Korea-China medical exchanges has been concentrated in the period after the mid-1950s, the impacts of China's medical support on North Korea during the Korean War period and the post-war recovery period have not been taken into account. In terms of these limitations, this study examined the medical activities by the Socialist camp of the Eastern European countries in North Korea after the Korean War. The medical aid teams from Hungary, Romania, Bulgaria, Czechoslovakia, Poland, and East Germany that came to North Korea in the wake of the Korean War continued to stay in North Korea after the war to build hospitals and train medical personnel. In the hospitals operated by these countries, cooperative medical care with North Korean medical personnel and medical technology education were conducted. Moreover, medical teams from each country in North Korea held seminars and conferences and exchanged knowledge with the North Korean medical field staffs. These activities by the Socialist countries in North Korea provided the North Korean medical personnel with the opportunity to directly experience the medical technology of each country. China's support was crucial to North Korea's ‘rediscovery’ of Korean medicine in the mid-1950s. After the Korean War, North Korea began to apply the Chinese-Western medicine integration policy, which was performed in China at that time, to the North Korean health care field through China's medical support and exchanges. In other words, China's emphasis on Chinese medicine and the integration of the Chinese-Western medicine were presented as one of the directions for medical development of North Korea in the 1950s, and the experiences of China in this process convinced North Korea that Korean medicine policy was appropriate. The decision-makers of the North Korean medical policies, who returned to North Korea after studying abroad in China at that time, actively introduced the experiences from China and constantly sought to learn about them. This study identified that a variety of external stimuli had complex impacts on the North Korean medical field in the gap between ‘Soviet learning’ in the late 1940s and the ‘autonomous’ medical development since the 1960s. The North Korean medical field was formed not by the unilateral or dominant influences of a single nation but by the stimulation from many nations and the various interactions in the process.

Contamination with sanitary microorganisms from Enterobacteriaceae, Pseudomonadaceae, Staphylococcaceae, Micrococcaceae and Bacillaceae families in flower bee pollen from Bulgaria after one-year vacuum-packed cold storage has been found. Dried flower bee pollens intended for human consumption were with high incidence rate of contamination with Pantoea sp. (P. agglomerans and P. agglomerans bgp6) (100%), Citrobacter freundii (47%), Proteus mirabilis (31.6%), Serratia odorifera (15.8%) and Proteus vulgaris (5.3%). Bee pollens were also positive for the culture of microorganisms from Staphylococcaceae, Micrococcaceae and Bacillaceae families: Staphylococcus hominis subsp hominis, Staphylococcus epidermidis, Arthrobacter globiformis, Bacillus pumilis, Bacillus subtilis and Bacillus amyloliquefaciens. It was concluded that, if consumed directly, the vacuum-packed cold stored dried bee pollen, harvested according hygienic requirements from bee hives in industrial pollution-free areas without intensive crop production, is not problem for healthy human.

Enterovirus 71(EV71), like polioviruses, invades the central nervous system to give rise to aseptic meningitis, encephalitis or myelitis. EV71 was first isolated in California in 1969 from a 9-month- old infant with encephalitis. Since then it has been isolated from the brain of children who died of encephalitis and from feces of patients with meningitis, encephalitis or paralysis. Related strains have been isolated from outbreaks of similar diseases in Australia, Sweden, Bulgaria and Hungary. We have experienced polio-like encephalomyelitis in a 3-month-old girl. Initial brain MR imaging showed tissue destruction in the bilateral posterior portions of the medulla oblongata and the bilateral anterior horns of cervical spinal cord from C3 to C6 level. Follow-up MR imaging was performed 3 months later, which showed minimal residual change on the anterior horn of the cervical spinal cord at C4 level only. This report deals with rare polio-like encephalomyelitis associated with EV71 and discusses its diagnosis and management. Brain stem and cervical spinal cord involvement are characteristic findings of EV encephalomyelitis.

Leptospirosis, a zoonotic disease that is caused by many serovars which are more than 200 in the world, is an emerging worldwide disease. Accurate and rapid diagnostic tests for leptospirosis are a critical step to diagnose the disease. There are some commercial kits available for diagnosis of leptospirosis, but the obscurity of a species- or genus-specific antigen of pathogenic Leptospira interrogans causes the reduced sensitivity and specificity. In this study, the polysaccharide derived from lipopolysaccharide (LPS) of nonpathogenic Leptospira biflexa serovar patoc was prepared, and the antigenicity was confirmed by immunoblot and enzyme linked immunosorbent assay (ELISA). The performance of the rapid diagnostic test (RDT) kit using the polysaccharide as a diagnostic antigen was evaluated in Korea, Bulgaria and Argentina. The sensitivity was 93.9%, 100%, and 81.0% and the specificity was 97.9%, 100%, and 95.4% in Korea (which is a rare region occurring with 2 serovars mostly), Bulgaria (epidemic region with 3 serovars chiefly) and Argentina (endemic region with 19 serovars mainly) respectively. These results indicate that this RDT is applicable for global diagnosis of leptospirosis. This rapid and effective diagnosis will be helpful for diagnosis and manage of leptospirosis to use and the polysaccharide of Leptospira may be called as genus specific antigen for diagnosis.

OBJECTIVE: Penetrating brain trauma (PBT) caused by gunshot is one of the most lethal traumatic brain injuries (TBIs) and its management and confrontation is of great importance. METHODS: The authors searched retrospectively the archives from 2 similar autonomous laboratories of forensic science and toxicology in the Balkan peninsula for a 10-year period of time and included only fatal penetrating brain injuries. RESULTS: The study is conducted in 61 cadavers with gunshot PBT. All of the cadavers were victims of suicide attempt. The most common anatomical localization on the skull were the facial bones, followed by skull base, temporal and parietal bone, conducting a trajectory of the gunshot. Additional findings were atherosclerosis of the blood vessels and chronic diseases such as chronic obstructive pulmonary disease, cancer and fatty liver. CONCLUSION: PBI has a high mortality rate. There are factors and findings from the collected data differing between the 2 aforementioned nations. Either way, better preventative measures, gun control and healthcare system are highly necessary.
