short chain fatty acid-induced colitis in mice.short-chain fatty acids (e.g. acetic, propionic and butyric acid) are metabolic products produced by colonic bacteria. since intra-rectal instillation of dilute acetic acid to rats and cats has been reported to produce a diffuse colitis similar to the human disease, in our study we have investigated the effect of intra-rectal butyric acid in mice. male bka mice (n = 6) received 01 ml of dilute butyric acid by intra-rectal instillation which was flushed out with saline after 10 sec. control anima ...19892634625
influence of naproxen on uterine pgf2 alpha and the antifertility effect of iuds in rats.an iud was implanted into one horn of the uterus in each of our experimental rats. the animals were mated with males of proven fertility about 2 weeks later. at day 1 of gestation (positive mating smear), the animals were treated with oral naproxen at 2 mg/kg per day or 20 mg/kg per day for 10 consecutive days. control animals received saline. at day 16 the animals were sacrificed and the implantation rates and fetal survival and pregnancy rates were determined. the iud completely prevented feta ...19892633796
[weaning from artificial respiration: value of continuous monitoring of mixed venous oxygen saturation].weaning from mechanical ventilation is particularly difficult in patients with combined cardiac and respiratory failure. continuous monitoring of mixed venous blood oxygen saturation (svo2) redefines weaning in terms of tissue oxygenation. a stable svo2 greater than 60% during weaning is a reliable index of weanability. however, further studies are required to establish a tolerance threshold for svo2 during weaning. in the limited experience reported here, an immediate and abrupt fall in svo2, w ...20042633669
[the role of the trs-glucotest apparatus in self-monitoring by patients with diabetes mellitus].successful treatment of diabetes mellitus requires a reliable control of glycaemia where self-monitoring with reflectometer plays a significant role. trs-glucotest reflectometer (trs, zagreb), the result of our experts' efforts, makes it possible for diabetic patients to perform self-monitoring. according to our research trs-glucotest reflectometer shows lower blood glucose levels for more than 20%, especially in 3.8-11.5 mmol/l range of glucose concentration, that is in the range most often exp ...20092633013
[prenatal diagnosis of congenital adrenal hyperplasia due to 21-hydroxylase enzyme deficiency].prenatal diagnosis of the "classical" forms of congenital adrenal hyperplasia (cah) which is a result of 21-hydroxylase (21-oh) deficiency either complete, with salt-wasting or incomplete without salt wasting, is performed in two ways: by measuring concentration of 17-hydroxyprogesterone (17-ohp) and androstendione (delta 4) in amniotic fluid and by hla typing of fetal cells from amniotic fluid. having ones own normal values is the basic condition for the safe prenatal diagnosis of cah 21-oh def ...20092633007
[prognostication of the development of degenerative-dystrophic lesions of the hip joint in dysplasia].examined were 184 children with dysplasia of the both hip joints and initial forms of a degenerative-dystrophic lesion. the roentgenologic signs of dysplasia of the hip joint, indicating the possible development of the degenerative-dystrophic lesion were established.20092632942
partial characterization of mycobacterium fortuitum and mycobacterium smegmatis auxotrophs by syntrophism using bacillus subtilis.syntrophism (cross-feeding) could be demonstrated between mutants of mycobacterium fortuitum and mycobacterium smegmatis, and previously characterized mutants of bacillus subtilis, auxotrophic for arginine, histidine, lysine or phenylalanine. based on this cross-feeding data, the possible site of blockage in the biosynthetic pathways of the mutants could be inferred.19892632668
bacterial and viral causes of acute diarrhoea in children in kuwait.bacterial and viral causes of acute diarrhoea were studied prospectively for one year in 343 hospitalised young children in kuwait. in 288 (84%) patients, one or more pathogens were identified compared with 12 of 86 (13.9%) children admitted with diseases other than diarrhoea (p less than 0.01). forty-four (12.9%) of the patients were infected with two or more pathogens. viral agents detected in the stools were rotaviruses (40.2%), enteric adenoviruses (1.7%), and enteroviruses (1.5%). enterobac ...19892632640
