[On postop strategies in surgically treated forms of ethmoid sinusitis]. / Problema posleoperatsionnoi taktiki pri khirurgicheskikh formakh gaimoroétmoidita.

146 patients were subjected to radical operations on the maxillary sinus with opening of the ethmoidal labyrinth cells. The superior effect of postoperative insertion of the latex tampon over gauze turunda was seen. Effective were also analgetics-antipiretics (paracetamol) and tactivin as medical correctors of early postoperative symptoms.

[Para-tonsillitis -- debatable questions of treatment techniques]. / Paratonzillit -- spornye voprosy lechebnoi taktiki.

The authors review variants of therapeutic policy in paratonsillitis. They think it necessary to perform in paratonsillar abscess abscess-tonsillectomy on the affected and tonsillectomy on the collateral side. Follow-up results are presented for cases of paratonsillitis treated in the ENT clinic of the Russian Medical University throughout 1990-1992.

[A trial of the possible joint use of mermithids and bacterial preparations for the control of mosquito larvae]. / Otsenka vozmozhnosti sovmestnogo primeneniia mermitid i bakterial'nykh preparatov dlia bor'by s lichinkami komarov.

The action of bacterial insecticides based on Bacillus thuringiensis H-14 and B. sphaericus in a dose of 0.005-2 mg/l on the mermithids Romanomermis iyengari, R. culicivorax and R. jingdeensis was studied. It was shown that though bacterial agents suppressed mermithid preparasite larvae density about 30-40%, the survivors might invade 100% of mosquito larvae. The viability and fertility of adult mermithids did not change under the influence of bactoculicide in doses 5-50 times higher than those used against mosquitoes in practice. In combined field trials of sphaerolarvicide (1.5 kg/ha) and R. iyengari mermithids the infectivity of Anopheles sacharovi larvae reached 96%. Mermithids in combination with bactoculicide and sphaerolarvicide might be useful in integrated control systems because these bacterial agents are harmless for mermithids of all stages in doses useful against mosquito larvae.

[A trial of Romanomermis iyengari and R. culicivorax mermithids as a means for controlling blood-sucking mosquitoes in the Tadzhik SSR]. / Ispytanie mermitid Romanomermis iyengari i R. culicivorax kak sredstva bor'by s krovososushchimi komarami v Tadzhikskoi SSR.

Field trials of R. iyengari and R. culicivorax in the biological control for the mosquito larvae were conducted in Parkhar, Kuibyshevsk, Gissar districts and the outskirts of the city of Dushanbe, the Tadjik SSR. Larvae of Anopheles superpictus, An. pulcherrimus and An. hyrcanus in a dosage of 1-5 thousand intact larvae per sq. m were invaded by mermithids. The mean infection rate was 46 per cent. The maximum infection rate was 98 per cent. It depended on several factors: the dosage of intact larvae, temperature, water salinity, water flowage in the waterbodies and their overgrowth with plants. Slow-flowed rice paddies and flow-free fresh waterbodies turned to be the proper sites for mermithids. The effect was higher in Anopheles than in Culex mosquitos.

[The mass rearing of the mermithid nematode Romanomermis culicivorax]. / Massovoe razvedenie nematod-mermitid Romanomermis culicivorax.

The procedure of mass laboratory rearing of mermithid nematode Romanomermis culicivorax, a parasite of mosquito larvae, is described. Culex pipiens molestus larvae are used as a host for cultivation at the host: preparasites ratios of 1:4-1:6, enabling to obtain the greatest mass of nematodes (over 500 mg per 1 thousand of infested mosquito larvae) when the male female ratio in culture was 1:1. This rearing technique allows to obtain on average 350 thousand invasive mermithid preparasites per 1 g of adult mermithids. The above-proposed method is compared to the procedure rearing described earlier by Petersen, Willis (1972).

[The prospects for using Romanomermis culicivorax and R. iyengari (Nematoda: Mermithidae) for mosquito control in Azerbaijan]. / Perspektivy ispol'zovaniia Romanomermis culicivorax i R. iyengari (Nematoda: Mermithidae) dlia bor'by s komarami v Azerbaidzhane.

The parasitic nematodes Romanomermis culicivorax and R. iyengari, were evaluated as a means of bloodsucking mosquito larvae control in Apsheron Peninsula (the city of Baku) and Lenkoran Lowland (Masally District) in Azerbaijan. Being once brought, mermithids got acclimatized in 12 shallow freshwater nonpolluted pools with aquatic flora and inhibited the emergence of 13-97% of mosquitoes during the summer period. R. culicivorax successfully survived the temporary drying (up to 2 weeks) in 3 and spent a winter in 2 water reservoirs. The possibility of R. iyengari settling via transmission of infected mosquito larvae from a "nursery" pool to a mermithid free water pool was proved. The larvae Cx. modestus, Cx. theileri, Ae. caspius and Ur. unguiculata are first registered as hosts of R. culicivorax and An. sacharovi, Cx. theileri and that of R. iyengari. Both mermithid species may be considered as a means of prolonged inhibition of mosquito emergence in the shallow nonpolluted fresh-water reservoirs in the Azerbaijan SSR.

[Trials to introduce Romanomermis culicivorax (Nematoda: Mermithidae), mosquito larva parasites, into the reservoirs of Voronezh and Moscow Province]. / Popytki introduktsii Romanomermis culicivorax (Nematoda: Mermithidae)--parazitov lichinok komarov--v vodoemy Voronezha i Moskovskoi oblasti.

Possibility of using Romanomermis culicivorax for mosquito control in the town of Voronezh and Moscow Province has been assessed. The infection rate of mosquito larvae didn't exceed 26% when preparasitic juveniles were released into water bodies at a ratio of 1-3 thousand per 1 m2 and temperature 18-25 degrees C. There were no evidences of mermithid settlement and hibernation in the water bodies of Voronezh. High efficacy of using R. culicivorax in mosquito larvae control can only be expected in these regions under hot summer conditions.

[Significance of viruses of antigen complex of California encephalitis in pathology]. / Znachenie virusov antigennogo kompleksa kaliforniiskogo éntsefalita v patologii.

A study was undertaken to examine 320 patients with seasonal fevers occurred in June to September. These included fever of unknown etiology, acute respiratory virus diseases, pneumonias, bronchitis, enterovirus diseases, and serous meningitis. Serological tests revealed that in 20 (6.3%) of them the viruses of the complex in California encephalitis (Tyagin's virus or antigenically related virus) contributed to the etiology of the disease. Major clinical symptoms of the disease were defined in this group of patients. The disease appeared as neuroinfections (serous meningitis), influenza-like conditions (fever, symptoms of intoxication), occasionally, infiltrative changes in the lung. Thus, the viruses of the antigen complex of California encephalitis makes an etiological contribution to infectious abnormalities.
