ВЛИЯНИЕ ЭКСТРАКТОВ СЛЮННЫХ ЖЕЛЕЗ КЛЕЩЕЙ HYALOMMA ANATOLICUM НА СОКРАТИТЕЛЬНУЮ АКТИВНОСТЬ ГЛАДКОМЫШЕЧНЫХ КЛЕТОК АОРТЫ КРЫСЫ

Immunization of cattle against Hyalomma anatolicum anatolicum using larval antigens.

Development of immunity in cross-bred (Bos taurus x Bos indicus) calves against Hyalomma anatolicum anatolicum, vector of bovine tropical theileriosis, was studied using larval antigen (LS) in Freund's complete adjuvant (FCA). Calves immunized with LS + FCA showed significant rejection of larvae (57.25 +/- 6.8) and nymphs (45.75 +/- 5.16). Abnormally fed larvae (11.4 +/- 0.8) and nymphs (8.25 +...

Type Ii Collagen Peptide Is Able to Accelerate Embryonic Chondrocyte Differentiation: an Association with Articular Cartilage Matrix Resorption in Osteoarthrosis

Цель. Исследовать влияние пептида коллагена 2-го типа (СР) на расщепление коллагена 2-го типа и дифференцировку эмбриональных хондроцитов разных морфотипов, выделенных из ростковой пластинки быка. Материал и методы. Бычьи хондроциты ростковой пластинки разделяли в градиенте перкола на морфотипы в соответствии с разными стадиями дифференцировки и далее культивировали в присутствии или без 10 мкМ...

Влияние Магнетизма На Регенерацию Effect of Magnetism on Regeneration

Natural infection rates and transmission of Theileria annulata by Hyalomma anatolicum anatolicum ticks in the Sudan.

Hyalomma anatolicum anatolicum nymphs were collected from two localities in the Sudan: Eddamer in Northern Sudan and Wad-Medani in Central Sudan. They were allowed to moult to adult ticks, which were assessed for Theileria infection in their salivary glands using Feulgen stain. At Eddamer, 49.6% of 123 ticks examined were infected with Theileria and the mean intensity of infection was 1.3 (i.e....

High infection rates of the tick Hyalomma anatolicum anatolicum with Trypanosoma theileri.

A crossbred calf (3 months old) obtained from a farm where regular control of ticks was practised and found to be free of blood parasites was inoculated with 20 ml pooled blood collected from four field cattle which had very low Trypanosoma theileri parasitaemias (one parasite per 70 microl blood as determined by the haematocrit centrifugation technique). Trypanosoma theileri was present in the...
