Effect of chlordane form on fetal development in rats

Oral administration of chlordimeform in a dose of 1.0 ml/kg b. wt. during the period of organogenesis [6th - 15th days of gestation] significantly decreased the fetal body weight and resulted in hyperplasia in heart and liver in 6 and 8% of feti of rats, respectively. It caused corrugation of some ribs and absence of sessamoid bones of fore and hind-limbs of feti. The acricide in doses of 8.5 and 17.0 mg/kg b. wt. caused early resorption of 90 and 100% of embryos. Chlordimeform significantly decreased the number of corpus leutum and implantation sites

Chromatographic analysis of decoys extracts used for control of haylomma dromedary ticks of camels

Chromatographic [thin layer chromatography, TLC and high pressure liquid chromatography, HPLC] analysis of cholesteryl esters of decoys prepared from female ticks of camels [Haylomma dromedarii] showed cholesteryl acetate, cholesteryl laurate and cholesteryl oleate, in concentration of 0.88053, 4.7433 and 2.5081 ug/5 decoys, respectively. These values decreased by time of attachment of the decoy to rabbits infested with male ticks till it became 0.6509, 2.0120 and 0 ug/5 decoys, respectively, after 20 days of attachment. Cholesteryl oleate disappeared from the decoy after 10 days of attachment. Mixing of cyfluthrin with 2,6-dichlorophenol [2,6-DCP] to the composition of decoys, their concentration decreased from time of attachment of them till they became 1.01231 and 0.004826 ug/5 decoys after 20 days. In vitro studies showed that addition of cyfluthrin to engorged female Haylomma dromedarii ticks in concentrations of 0.15 and 0.075/100 ml water, respectively, died within 30 days while their keeping in cyfluthrin in concentration of 0.6 ml/100 ml water caused their death within 7 days without egg production
