The aim of the present study was to confirm observations on the vertical transmission of Schistosoma japonicum in the rabbit. S. japonicum- infected pregnant rabbits were used in this study. Perfusion of mother rabbits was done 9weeks after infection in order to obtain worm bur- dens in relation to their initial cercarial ***- schistosoma specific Ig M antibodies in serum samples collected from rabbit kittens were detected by EL *** results showed that gestation period lasted the norm al2 9- *** the exposed mother rabbits became infected with S. *** Ig M antibody OD values were detected in12 out of the6 0 kittens exam ined (2 0 .0 % ) . In group C and A,4 0 .0 % and 17.9% of the kitten were congenitally infected,re- spectively. 18.1% of the kittens born to mothers infected with a single dose of 2 0 0 cercariae per rabbit were positives;this is not significantly different from that obtained for the 6 0 0 dose group (2 2 .2 % ) .Three randomly selected Ig M+ kittens harbored between one and two adult worm s. The livers of these kittens displayed granulomatous lesions. It is concluded that congenital S. japonicum infection does occur in the rabbit and is affected by the m other stage of pregnancy and to a lesser extent by its infection load.

In this paper effects of various injection molding parameters on tribological properties of ultra-high molecular weight polyethylene （UHMWPE） were investigated. The tribological properties like coefficient of friction and wear rate were obtained from the experimental results of hip simulator which was designed and fabricated in the laboratory. Bovine serum was used as a lubricant in this study. In addition, the hardness of the specimen was also investigated as well. The injection molding parameters that varied for this study are melt temperature, injection velocity and compaction time. The results show that contact loads and melt temperature were mostly influenced the tribological behavior of UHMWPE. A wear mechanism map was developed to study the dominant wear mechanism that influences the wear behavior of UHMWPE. SEM was employed to study the worn out morphologies of UHMWPE. The dominant wear mechanisms that are dominated through our study are ironing, scratching, ploughing, plastic deformation, and fatigue wear.

Flavonoids, anthocyanins, antioxidant capability, total phenolic, ascorbic acid contents, and essential oils compounds of Ziziphora tenuoir(Lamiaceae) for polar and non-polar subfraction in different stages of growth(pre-flowering and flowering) were evaluated in this work. Antioxidant activities of the samples were determined by three testing systems namely DPPH, β-carotene/linoleic acid, and reducing power assay. In the DPPH system, the highest radical scavenging activity was seen by the nonpolar subfraction of the methanol extract in the flowering stage(IC50 43.17 ± 3.68 μg·mL–1). Large differences in the amount of phenolic compounds, antioxidant activity, anthocyanins, and flavonoids of Z. tenuoir in two stages of growth were detected. The chemical composition of the hydrodistilled essential oil of the aerial parts of Z. tenuoir was analyzed by GC/MS and compared in the two stages of growth. The main constituents of the 28 identified compounds in the oil were found to be pulegone(67.34% vs 59.61%), β-humulene(3.24% vs 3.25%), and limonene(5.06% vs 2.57%) at the flowering and pre-flowering stages, respectively.
