Background: In 1889, keratinocytes conjunctivitis with eruption in the form of Epidemic first was revealed by Fuchs and from 1995 it began to be diagnoses using the polymerase chain reaction. In our country annually about 11,850 patients visited the ophthalmology cabinet of the State Central Clinical Hospital, and from them 1290 cases or 10.89% were diagnosed to have viral infections, including 95% were sick of adenovirus infection, 3.7% had a herpes virus infection, 1,3% infection of other species respectively. At the international level of experience and research on the treatment of adenovirus conducted in a large circle, and immunoglobulin therapy has a high impact (P=0.0001, power 0.7599, ANOVA). In Mongolia, normal immunoglobulin is produced and widely uses to enhance immunity, but technological expertise and experiences on the use of immune globulin in ocular diseases caused by adenovirus infection had not been conducted yet.
Goal: To study the possibility to diagnose ocular diseases caused by adenovirus infection with laboratory method and use immunoglobulin in eye area.
Methods and materials: The investigation involved 50 patients aged 18-55 diagnosed with the infection of adenovirus. We took samples from eye conjunctiva, blood and stool of patients involved in the investigation and conducted a survey to identify adenovirus using the polymerase chain reaction. In this analysis it was used the diagnosing devise (Amply Sense Adenovirus – Eph) made in Russian Federation. Samples where the virus is detected were multiplied in Hep2 cell culture and viruses were abstracted. Linear cells Hep2 were made culture by methodology and recommendation from World Health Organization. Abstracted viruses were challenged in experimental rabbits by dropping it into their eyes or making injections. After rabbits became completely sick, they were divided into five groups and each had a different treatment. Statistical and analytical software used in the development of research. (SPSS,EPI-info8 STATA).
Results: Samples were taken from 50 people and made on them polymerase chain reaction analysis, at 43 (86%) of which were detected adenovirus: Viruses were found in 14(93%) of 15 samples taken from the eye, 12 (80%) of 15 samples taken from the blood, 17(85%) of 20 samples taken from the stool respectively. Sample with viruses was conducted the initial development and made culture in a linear cell Hep 2. Partial anesthesia were made on both eyes of 25 rabbits with use of Proparacaine Hydrochloride and infected them with adenovirus and after 7 days the following treatments were made dividing the rabbits in five groups so that each group has got five rabbits. (Treatment with interferon, ingavirin treatment against viruses, immunoglobulin drops, combined immunoglobulin drops jointly with ingavirin, immunoglobulin injection for combined with ingavirin). After infection eyes of rabbits with adenovirus and descending corneous phlegmon in their eyes, the symptom curing were observed on schedule at 2, 4, 6, 8, 10, 12, and 14th days of each separate treatment group and calculated the average. On the 8th day after starting the treatment combined ingavirin with lg eye drop and treatment lg catarrh injection with ingavirin conducted in related groups, and on the 12th day of treatment with ingavirin, all the symptoms of infections were completely cured. Treatability of group treated with interferon after 14 days was 71 percent.
On the basis of the above indicators, we compared the most effective method of treatment with interferon treatment, which is currently in use, then developed a method of statistical significance of the study with indicator ANOVA and proved that the significance of the treatment is of P<0.05. As in the 8th day of the treatment, the symptoms of viral infection is completely eliminated, and at the 10th day is not detected any viruses, we can prove that the treatment of immune globulin effectively prevents the virus and is capable of neutralizing the virus.
Conclusions:
1. The experiment shows that intravenous immunoglobulin therapy is an effective method against infection caused by adenovirus.
2. Since immunoglobulin counteracts the adenovirus, it has the opportunity to become a major application against inflammation caused by viruses and bacteria
3. Using of the drug against the virus with a combination of ingavirin has higher effectiveness than the use of only one immunoglobulin against adenovirus.

BackgroundIn 1988, the Forty-first World Health Assembly adopted a resolution for the Global Polio Eradication.Since the initiative was launched, number of polio cases has fallen by over 99%. Today, only threecountries in the world, Afghanistan, Pakistan and Nigeria - remain polio-endemic. The Polio Eradicationand Endgame Strategic Plan of 2013-2018 calls for the gradual eradication of wild virus strain and thevaccine virus strain at the same time. In order to prevent the border transmission of wild type poliovirus,virus leakage from laboratories, it is required to conduct inventory of laboratories handling poliovirus andpotential infectious materials every 2 year.GoalTo identify laboratories handling poliovirus and potential infectious materialsMethodsSurvey of laboratories handling poliovirus and potential infectious materials was conducted amongstate, private, clinical, biomedical and environmental testing in total of 127 laboratories operating in21 provinces and 9 districts of Ulaanbaatar city by questionnaire. Survey questionnaire consists of 6sections (general, sample storage, laboratory biosafety, staff knowledge, information source, trainingand etc.). Study results were processed using SPSS-19 statistical programme.Results34.7% of 96 biomedical laboratories were analyzed stool samples. These laboratories were analyzedrotavirus (17.0%), intestinal bacteria (67.0%), Helicobacter (14.3%), parasite and other indicators (1.7%)in stool samples. 43.8% of laboratories were stored stool samples for one day and 3.1% up to oneyear. From 31 environmental testing laboratories 73.3% were bacterialdetection test on environmentalsamples. 60% of wastewater samples were collected from rivers, 16% on entrance to wastewatertreatment plant and after biological treatment combined, and 24% from other sources. Soil sampleswere collected near waste disposal and other sources (46.4%), and from unknown sources (53.6%).24.1% of all laboratories were stored environmental samples for 3 days, 3.4% for 45 days. Accordingto results, surveyed laboratories did not store samples for more than 1 year. Also, none of surveyedlaboratories (100%) were not stored poliovirus and potential infectious materials.Conclusion· The investigated laboratories were not stored poliovirus and potential infectious materials.· The biosafety and biosecurity status of laboratories should be improved in near future throughenhancing knowledge of laboratory workers and organizing training related to biosafetyandbiosecurity.
