This study aimed to investigate the absorption mechanism of three curcumin constituents in rat small intestines. Self-emulsification was used to solubilize the three curcumin constituents, and the rat in situ intestinal perfusion method was used to study factors on drug absorption, including drug mass concentration, absorption site, and the different types and concentrations of absorption inhib...

Two enzymes were examined as potential indicators of early precancerous changes. Ornithine decarboxylase, an enzyme normally associated with rapid cell division, is low in the rapidly dividing, cancer-susceptible colon. The level of this enzyme was also very high in the nondividing cells of the small intestines. Administration of an intestinal carcinogen, dimethylhydrazine, led to a large incre...

In two cases of infantilism there was poor absorption from the intestines of nitrogen, sulphur, phosphorus, calcium, and magnesium. The excretion of these elements in the urine was low. The excretion of calcium in the urine was so small as to be negligible. The excretion of calcium into the intestines was increased. The complete balance experiments showed that while other elements were retained...

In the experiments reported in the preceding paper (p. 597) it was found that lactose, fed to hens, does not appear in the excreta in appreciable quantities until excessive amounts are administered—a finding thoroughly in agreement with our present knowledge of sugar-feeding in human beings. Since lactose is assimilated from the alimentary canal of chickens, and since assimilation of disacchari...

of children by these very peculiar beetles. Whether they enter by the mouth as an egg and undergo development into larva and pupa and finally into the adult beetle within the intestines, or whether they enter per rectum while children defecate in the open is not certain. Senior-White was the first to note that Onthophagus bifasciatus. Fb. (Copridae) infested the intestines. I have since observe...

One prediction of optimal digestion theory is that organisms will increase the relative length of their digestive tracts when food resources become limited. We used theory of optimal digestion to test whether tadpoles can adjust the relative length of their intestines when challenged with the fungal pathogen Batrachochytrium dendrobatidis (Bd). The degree of tadpole mouthpart damage, a symptom ...

After manual and machine cleaning of beef intestines, the structure of the intestinal layer was examined. Examination was performed using a histological technique and included 60 intestinal sets of fattened beef (Simmental breed), 10 months of age and with an average slaughter weight of 248.05 kg. Intestines are considered to be edible by-products and therefore are used as natural casings for h...

Two experiments were conducted to determine the concentration of DE and ME and the standardized ileal digestibility (SID) of AA in chicken meal, poultry byproduct meal, hydrolyzed porcine intestines, a spent hen–soybean meal (SBM) mixture, and conventional SBM fed to weanling pigs. In Exp. 1, 48 barrows (initial BW: 14.6 ± 2.2 kg) were placed in metabolism cages and allotted to 6 diets with 8 r...

This study aimed to explore the histomorphology of pancreatic tissue medaka fish develop as a diabetic animal model. Adult were obtained with body length 2.53±0.22 cm and weight 265.8±25 g. Medaka fixed using Boiun's fixative solution. Macro anatomical observations pancreas conducted stereomicroscope. Histological preparations made according Hematoxylin-eosin staining standard procedure. Pancre...
