Metabolites of furazolidone in urine of chickens.
Colostomized chickens were medicated with single oral doses of the antibacterial furazolidone. An average of 7.5 ± 3.0% of the dose was excreted in the urine within 12 hr. as compounds measured by a procedure in which they react to form 5-nitrofurfural phenylhydrazone. Chromatographic analysis delected four metabolites containing a furan ring. Only one metabolite reacted to form 5-nitrofurfural phenylhydrazone. Elimination of the metabolites with a furan ring was complete in 12 hr. Only traces of furazolidone were detected by the chromatographic procedure.
The Artificial Anus in the Bird
Abstract IN BIRDS, studies on separately voided urine and feces are best carried out by means of an artificial anus. Although feces-free urine can be collected in the bird by catheterization, and urine-free feces by ligation of the ureters, such techniques induce abnormal changes in the animal, and are not suitable for more than acute experiments. With the artificial anus, however, a nearly normal animal is obtained. The cloaca serves as a urinary bladder and still functions to resorb water. The distal end of the rectum is brought through the body wall and everted on itself to serve as an anal opening. Separate or simultaneous urine and feces collections can be made on the same animal. Although the usefulness of such a physiological preparation is obvious, there are very few references to it in the literature. In addition, the ones that do exist give no hint in their titles that they . . .
Phytochemical and FT-IR Spectral Analysis of Certain Bamboo Species of SouthIndia
Bamboo with its varied uses has historically been an integral part of livelihoods and lifestyles in India. The present study was carried out to characterize the bioactive constituents present in the leaf extracts of certain bamboo species using Fourier transform infrared spectroscopic analysis (FT-IR). The various solvent extracts of various bamboo leaves subjected to qualitative analysis showed the availability of phytoconstituents including alkaloids, phenolic compounds, flavonoids, saponins, glycosides, terpenoids, steroids, coumarins and phytosterols. Quinones were completely absent in all the five bamboo species. The FT-IR spectrum confirmed the presence of sulphides (SS), phenols (C-O), aromatic compounds, thiols (S-H), aliphatic compounds (C-Cl) and amines (NH) in different bamboo species. The present investigation has also opened avenues for further research into the development of potent phytomedicines from different bamboo species.
