Some chemical additives to increase the activity spectrum of bacillus thuringiensis var. kurstaki [dipel 2x] against the rice moth corcyra cephalonica

Some chemical additives have been adopted to increase the potency of D-endotoxin of Bacillus thuringiensis var. Kurstaki [Dipel 2x] against the rice moth Corcyra cephalonica. Procedures were based on the incorporation of some selected essentially non toxic and low cost compounds with different modes of action with the endotoxin to increase its activity. Among the compounds tested were some inorganic salts, nitrogenous compounds, protein solubilizing agents, sugars, some plant powders and some plant extracts

Immunological aspects of infertility in cows and buffaloes in Egypt

The present investigation revealed that the immunological reaction between the cervical mucus of repeat breeder cow and washedl spermatozoa gave a higher titre. On the other hand the reaction of the cervical mucus of normal cow and buffalo-cow with the seminal plasma gave a low agglutinating titre. The influence of the cervical mucus of repeat breeder cow- and buffalo-cow on the homologus bull semen gave a higher reaction than that with the heterologous bull semen. The results were attributed to the presence of agglutinating and immobilizing antibodies against the semen in the cervical mucus of the repeat breeder cows and buffalo-cows

Serum total protein and protein electrophoretic pattern of buffalo fetus during development

Changes in serum total protein and protein fractionation of buffalo fetus were studied from 5[th] to 10[th] months of gestational age. The total protein concentration increased progressively with a prominent increase in albumin near term. The data obtained revealed five serum peotein fractions in buffalo fetus. These fractions were prealbumin, albumin, alphafeto-protein, transferring and gamma globulin. The gamma globulin started to apprar in the fetal serum at 6[th] month of gestational age
