Immature rat Sertoli cells were cultured for 7 to 14 days on Millipore filters impregnated with a reconstituted basement membrane extract in dual-environment (bicameral) culture chambers. Electron microscopy of the cultured cells revealed the presence of rod-shaped mitochondria, Golgi apparatus, rough endoplasmic reticulum, and Sertoli-Sertoli tight(More)
For analysing the injurious mechanism of Trichosanthin (TCS) on trophoblast cells, cytotrophoblast cells were separated from placental villi in human early pregnancy and cultured on millipore filters coated with collagen in dual-environmental culture chambers. After 7-10 days culture the cells grew into confluent monolayer. A lot of multinucleated giant(More)
The endogenous β-galactosidase expressed in intestinal microbes is demonstrated to help humans in lactose usage, and treatment associated with the promotion of beneficial microorganism in the gut is correlated with lactose tolerance. From this point, a kind of recombinant live β-galactosidase delivery system using food-grade protein expression techniques(More)
OBJECTIVE To observe the influences of bifidobacterium on glucose and lipid metabolism and intestinal flora in type 2 diabetes mellitus rats. METHODS Rats were randomly divided into 4 groups, the blank control group was fed with basic forage, the other 3 groups were fed with high fat diet. Meanwhile the high-dose and low-dose groups were gavage(More)
Objective: To study changes in expression of claudin-11 and proteins related to mitogen-activated protein kinase (MAPK) signaling pathways, as well as the ultrastructure of the blood testis barrier (BTB), in male ICR mice exposed to decabromodiphenyl ether (BDE-209). Methods: Fifty-two mice, 4 weeks of age, weighing 15-21 g, were provided with adaptive(More)
Objective: To investigate the clinical and immunological laboratory features, mutations in SH2D1A gene and SAP protein expression in four children of two families with X-linked lymphoproliferative disease type 1(XLP-1). Method: Four patients (Family A including Patient 1 and Patient 2, Family B including Patient 3 and Patient 4) and their maternal relatives(More)
Urodeles are the unique vertebrate which can regenerate their limbs in larvae and adult. The pattern formation of blastema cells in the limb regeneration is a central problem. Many evidence have been established to support the hypothesis that RA may be the morphogen in limb development. The limb development and regeneration are so similar morphogenetic(More)

The spontaneous potentials (SPs) of nerveless embryonic epithelium of Cynops orientalis were observed by conventional intracellular micro-electrode technique. The amplitude and frequency of SPs of epithelial cells and the course of initiation and decline were recorded. The SPs can occur repeatedly at the stages when the embryonic epithelium is able to(More)
