The gut microflora is an important constituent in the intestinal mucosal barrier and has been introduced as the concept of probiotic therapy that beneficially affects the host by improving its intestinal microbial balance. Therefore, the main objective of the study was to explore the protective potential of various lactobacilli strains for murine giardiasis. By experimentation, it was found tha...

Use of a visible laser in an Aminco “Rotochem” centrifugal analyzer enables light-scattering measurements to be made with this instrument. The modification is technically simple, inexpensive, and requires no fundamental changes in basic instrument design. The laser-modified analyzer has been applied to the measurement of lgG in serum. A two-point kinetic analysis is used to quantitate lgG from ...

Objective: Study the influence of pre-competition intensive training on B lymphocyte immunity of excellent track and field athletes. Method: Select 10 excellent track and field athletes of the school to receive pre-competition intensive training and observe the influence of long-time training and competition on B lymphocyte immunity of these athletes. Result: In this study, the concentration of...

In a previous communication (Barber et al. [1 ] ) it has been shown that there exists in human serum a cobalt-activatable enzyme which splits 1leucylglycylglycine (LGG). The rate of hydrolysis in normal adult individuals is between 5.5 and 8.5% per hour (in the previous communication the rate of hydrolysis of LGG by serum of normal adult controls was stated to be 6.1 to 7.8%o per hour. This val...

The strong ropy character of the Scandinavian fermented milk viili is conferred by the exopolysaccharides (EPS) produced by lactococcal strains. These biopolymers can be responsible for some health benefits. We have assessed the influence of the EPS fraction isolated from commercial viili on the adhesion of some probiotics and pathogens to human intestinal mucus. Concentrations of viili EPS gre...

lsologous antigenic determinants of y-globulin revealed by proteolytic digestion of the globulin molecules were discovered by Osterland, Harboe, and Kunkel (1963) in human lgG and by Mandy, Fudenberg, and Lewis (1965) in rabbit y G. These determinants are detected by autologous and isologous antibodies found in most human sera and in all rabbit sera, respectively. These antibodies were named pe...

The concentration of fecal mucin and the adhesion of specific probiotics and their combinations in the intestinal mucus of infants during and after rotavirus diarrhea and in healthy children were determined. Mucus was prepared from fecal samples from 20 infants during and after rotavirus diarrhea and from 10 healthy age-matched children. Mucin concentration was determined, and the adhesion of f...

A chromosomal locus encoding biosynthetic genes for a putative peptide synthetase of Pseudomonas fluorescens was identified and cloned. To achieve this, two sets of degenerated oligonucleotide primers KAGGA:SGTTG and TGD:LGG were used in PCR. These primers were selected based on highly conserved units of known peptide synthetases involved in adenylation and thiolation regions of Bacillus subtil...

A complete ring of neutral hydrogen gas (HI) in the LGG 138 group of galaxies has been found. The HI mass of the ring is greater than 10 h−2 75 M ̄, and the gas appears to be rotating with a projected circular speed of ∼200 km s−1. Two bright galaxies are enclosed by the ring, both having radial velocities consistent with membership of the group. Faint stellar emission extends to the radial dist...
