Abstract Calotropis species have been used in the traditional medicinal system for the treatment of
diseases of the liver and abdomen. In view of the antioxidant and anti-hyperglycemic properties of an aqueous suspension obtained from the dried latex of Calotropis procera, the present study was carried out to
evaluate its efficacy in affording protection against alloxan induced changes in rat kidney. A single intraperitoneal injection of alloxan (150 mg/kg) in rats produced hyperglycemia within 3 days and altered kidney
functions over a period of 90 days. Daily oral administration of the aqueous suspension (100 and 400 mg/kg)
in diabetic rats produced… More >

Abstract Apigenin, a nonmutagenic flavonoid, has been shown to possess free radical scavenging activities, anticarcinogenic properties, antioxidant and anti-inflammatory effects. Recently, apigenin was reported
to cause gastric relaxation in murine. To assess possible effects of apigenin on migration of bladder smooth
muscle (SM) cell, we isolated SM cells from peri-cancer tissue of human bladder and established a cell model
that was capable to overexpress transiently MEKK1 (MEK kinase 1). Results showed that overexpression of
active human MEKK1 by adenoviruses infection induced migration of human bladder smooth muscle (hBSM)
cells and phosphorylation of MAPKs, ERK, JNK and p38, which are the downstream… More >

Abstract Junctional devices in Sertoli cells conform the blood-testis barrier and play a key role in
maturation and differentiation of germ cells. The spacial distribution of ectoplasmic specializations of Sertoli
cells was studied by β-actin immunolabelling, using laser confocal and transmission electron microscopy. For
confocal microscopy, β-actin immunolabelling of ectoplasmic specializations was studied over the background of either prosaposin or glutaredoxin immunolabelling of the Sertoli cytoplasm. Labelling was found
near the basal lamina, surrounding early spermatocytes (presumably in leptotene-zygotene) or at one of two
levels in the seminiferous epithelium: (1) around deep infoldings of the Sertoli cell cytoplasm, in tubular
stages… More >
