phorbol/diarrhea

The toxic kernel cake of Jatropha curcas (KCakeJ) is an emerging health and environmental concern. Although phorbol esters are widely recognized as the major toxin of KCakeJ, convincing evidence is absent. Here, we show that rather than phorbol esters an isomeric mixture of

Bovine viral diarrhea (BVD) virus inhibited phytohemagglutinin (PHA)-, PHA plus phorbol-12-myristate-13 acetate (PMA)- or PHA plus calcium ionophore (A23187)-stimulated bovine peripheral blood mononuclear cell (PBMC) proliferation. Further, BVD-virus inhibited A23187-stimulated leukotriene B4 (LTB4)

BACKGROUND Cortex Phellodendri is derived from the dried bark of Phellodendron chinense Schneid. or Phellodendron amurense Rupr. Traditionally, Cortex Phellodendron Chinensis (CPC) and Cortex Phellodendron Amurensis (CPA) are used interchangeably under the name "Huang Bai" for the treatment of

Photodynamically induced virus inactivation appears promising in preventing transmission of enveloped virus infections in transfusible blood products. The potential for utilizing hypericin as a photosensitizer to inactivate key enveloped viruses in packed red cell concentrates (PRC) was evaluated.

The dried roots of Sophora flavescens Aiton (SFA) has been used in traditional medicine for treatment of inflammation, gastrointestinal hemorrhage, diarrhea, and asthma. In the present study, we investigated the effect of SFA on the inflammatory allergic reaction using human mast cell-1 (HMC-1). SFA

The heat-stable enterotoxin STa of E. coli causes diarrhea by binding to and stimulating intestinal membrane-bound guanylyl cyclase, triggering production of cyclic GMP. Agents which stimulate protein kinase C (PKC), including phorbol esters, synergistically enhance STa effects on cGMP and

The major function of the adult colon is to reabsorb fluid from the chyme. This ability to conserve salt and water is especially important in newborns, where reserves are small and diarrhea is frequent. Although much is known about regulation of Cl- transport in the adult colon, postnatal changes in

In secretory epithelia, activation of PKC by phorbol ester and carbachol negatively regulates Cl(-) secretion, the transport event of secretory diarrhea. Previous studies have implicated the basolateral Na(+)-K(+)-2Cl(-) cotransporter (NKCC1) as a target of PKC-dependent inhibition of Cl(-)

Enteropathogenic Escherichia coli (EPEC) is a common cause of diarrhea in children in developing countries. Protein kinase C (PKC), a serine- and threonine-directed protein kinase, is rapidly activated following EPEC infection and this is accompanied by its translocation to a membrane-bound location

BACKGROUND Luminal fluid sequestration and diarrhea are early manifestations of mesenteric ischemia. This can be modeled in vitro with the use of T84 intestinal epithelia, where ischemia induces Cl(-) secretion with adenosine-mediated autocrine feedback. Protein kinase C (PKC) regulates epithelial

BACKGROUND The purpose of the present study was to determine whether vasoactive intestinal polypeptide (VIP) is released from the tumor cells of VIPoma and if so then to attempt to show how its release is regulated by cultured human VIPoma cells. METHODS A resected specimen of a pancreatic tumor

Failure to absorb bile acids by the ileum leads to fluid secretion by the colon and diarrhea in adults. The infant ileum, however, does not actively transport bile acids. Therefore, we investigated the effect of taurodeoxycholic acid (TDCA) on ion transport in the colon of rabbits 7-10 days old. We

OBJECTIVE The study was conducted to investigate the effects of replacing soybean meal (SBM) with different levels of detoxified Jatropha curcas kernel meal (DJM) in growing pig diets on growth performance, nutrients digestibility and meat edibility. METHODS A total of 144 pigs with initial body

Recent development of imaging tools such as computed tomography, ultrasonography, and magnetic resonance imaging have incidentally discovered hormonally functioning or nonfunctioning adrenal tumors. Most adrenal medullary tumors are pheochromocytomas and neuroblastoma group tumors. They are
