Clinical myiasis. | Human clinical myiasis is a rare entity in temperate zones, but it is of frequent occurrence among indigenous populations in tropical countries. The physician in practice in temperate zones, especially in urban areas, will generally see cases in those who have returned from rural travel or duty tours in tropical countr... | 522,188 | [

[Autolock bands in encircling procedures (author's transl)]. | Several modifications of autolock bands for retinal detachment surgery were tested. The most favourable results were achieved with a conical lock type applied to one end of the band. A controlled shortening to produce a calculated scleral indentation can be obtained by a millimeter scale. | 522,415 | [

Extracellular lectin and its glycosaminoglycan inhibitor in chick muscle cultures. | Embryonic chick muscle contains two developmentally regulated lectins, which may be involved in cell interactions. These endogenous lectins are assayed as agglutinins of appropriate test erythrocytes.

[Primary mechanism of a reduction in the intensity of extremely weak mitochondrial luminescence in the process of chemical hepatic carcinogenesis]. | The induced chemoluminescence in rat liver mitochondrial preparations was studied in the course of 2-acetylaminofluorene or N-nitrozodiethylamine induced hepatocarcinogenesis. As follows from the literature, the intensity of chemoluminescence is representative of catalase activity, i. e. of one of mitochondrial enzymes... | 524,462 | [
