bromelain/dental caries

The ratio of lipopolysaccharide (LPS)-reactive B cells specific for bromelain-treated mouse erythrocytes (BrMRBC) to general LPS-reactive B cells is far higher in the peritoneal cavity of normal mice than in their spleen. To investigate the high concentration of anti-BrMRBC LPS-reactive B cells in

Normal snapper (Pagrus auratus Bloch and Schneider) serum was examined for natural IgM that binds to protease (bromelain) treated sheep erythrocytes (BrSRBC) in a model assay system that has been used to appraise natural IgM of various mammals. Normal snapper serum lysed BrSRBC while haemolysis was

A preliminary experiment showed that the supernatants of in vitro cultured peritoneal cells (rich in Ly-1 B cell subset shown to secrete most IgM autoantibodies against bromelain-treated mouse red blood cells (BrMRBC) and DNA) from different mouse strains did not contain any significant antibody

We have studied the relationship between B cell reactivity to bromelain-treated autologous mouse erythrocytes (BrMRBC) and expression of the VH11 gene family in splenic, peritoneal and pleuropericardial cell populations from normal C57BL/6 mice. B lymphocytes producing antibodies to BrMRBC were

Low-density lipoproteins from chicken egg yolk (EyLDL), which are reactive with mouse antibodies against bromelain-treated mouse erythrocytes (BrMRBC), were conjugated with fluorescein isothiocyanate (FITC). FITC-EyLDL could bind specifically to mouse anti-phospholipid B cells, which comprised all

In lymphoid tissues of mice, there exist LPS-reactive B cells which can differentiate to IgM-secreting plaque-forming cells (IgM-PFC) and PFC secreting antibodies against bromelain-treated mouse erythrocytes (BrMRBC) by LPS activation. In this study, four groups of LPS-reactive B cells in spleen,

As part of an evolutionary layered hematopoietic system, the B lymphocyte compartment consists of different lineages of B lymphocytes, which evolve sequentially during ontogeny. In mice, there is ample evidence for the existence of at least two lineages, a layer of B-1 cells (Ly-1 B cells) and the

The ontogenic development of B cell clonal precursors (BCP) reactive to bromelain-treated, syngeneic erythrocytes (BrMRC) and to single-stranded DNA has been studied by limiting dilution of both spleen and peritoneal cells. It was found that the frequency of anti-BrMRC BCP in the spleen is very low

OBJECTIVE The objective of this study is to assess the deproteinizing effect of bromelain enzyme and compare it with neodymium-doped yttrium aluminum garnet (Nd:YAG) laser and 10% sodium hypochlorite (NaOCl) by using scanning electron microscope (SEM) and polarized microscope. METHODS A total of 60

Bromelain, a mixture of proteases derived from pineapple stem, has been reported to have therapeutic benefits in a variety of inflammatory diseases, including murine inflammatory bowel disease. The purpose of this work was to understand potential mechanisms for this anti-inflammatory activity.

Acid unfolding of non-inhibited papain at pH 2 was studied by means of spectroscopic and electrophoresis techniques as well as activity assays. We found a molten globule like species (A state) similar to that previously reported for bromelain and S-carboxy-methyl-papain. We demonstrated that this A

Pleurisy was induced in rats by an intrapleural injection of 0.5 ml of 1% kaolin. The exudation of plasma into the pleural cavity showed two peaks at 20 min and 3-5 h after the kaolin injection. The volume of the pleural fluid increased gradually up to 5 h. The effects of treatment with mepyramine,

A mode of interaction of bradykinin with prostaglandins (PGs) in pain were compared with that in acute inflammation. When pain production was measured as an increase in reflex hypertensive response of the lightly anesthetized dogs after intrasplenic injection of bradykinin, the response was

Rat pleurisy was induced by intrapleural injection of lambda-carrageenin. The pleural exudate began to be accumulated 1-3 h after carrageenin administration and showed a peak at 19 h. The levels of prekallikrein and high-molecular-weight (HMW), but not low-molecular-weight (LMW), kininogen in the
