The Guinea Hen

Transferrin of the Hen

It is well known that in the hen the egg-white protein ovotransferrin (conalbumin) and the serum protein transferrin are very similar in structure and iron-binding properties (for review see Beam & Parker, 1966). Since it is evident that for the eggwhite protein the name 'ovotransferrin' (Komatsu & Feeney, 1967; Azari & Baugh, 1967) is more informative than the classical name 'conalbumin', it i...

Histidine-114 at subsites E and F can explain the characteristic enzymatic activity of guinea hen egg-white lysozyme.

The courses of the reaction catalyzed by guinea hen egg-white lysozyme (GHL), in which Asn113 and Arg114 at subsites E and F in hen egg-white lysozyme (HEL) are replaced by Lys and His, respectively, was studied with the substrate N-acetylglucosamine pentamer, (GlcNAc)5. Although GHL was found to retain the main-chain folding similar to HEL as judged from CD spectroscopy, the courses of GHL sho...

A critical review of the therapeutic potential of dibenzyl trisulphide isolated from Petiveria alliacea L (guinea hen weed, anamu).

The data compiled in the present review on dibenzyl trisulphide (DTS) isolated from Petiveria alliacea L (the guinea hen weed or anamu) revealed that the compound and its derivatives could be of tremendous pharmaceutical interest. The mode of action elucidated for DTS revealed that it is a mitogen activated protein extracellular regulated kinases 1 and 2 (MAPKinases erk1 and erk 2) signal trans...

Ovarian tumors of the hen.

Present available information regarding ovarian tumors in hens is incomplete in most aspects, and this lack of knowledge hampers use of hens as models for study of ovarian cancer. A study of 466 hens ranging from 2 to 7 years of age and covering a period of more than 3 years has provided much needed information relative to reproductive tract neoplasia. On the basis of this study, it is apparent...
