The present study was aimed to study the light and electron microscopic studies of thymic Hassall's corpuscles was done in various age groups of Nandanam Chicken ranging from day-old to forty weeks. Hassall's corpuscles are special, unique structures present in thymic medulla and also in the cortex of all the age groups of Nandanam chicken (from hatch to forty weeks) in the present study. Size ...

After collecting calcareous corpuscles from plerocercoid of Spirometra mansoni (sparganum), we evaluated the antigenic values of calcareous corpuscles binding proteins obtained from the cyst fluid of Taenia solium metacestodes. Immunoblot analysis revealed that cysticercosis patient sera strongly recognized 10 and 95 kDa calcareous corpuscles binding proteins. This result demonstrated that calc...

Herbst corpuscles are widely distributed throughout the oropharynx of the ostrich and emu in contrast to the general situation in birds. Knowledge of the comparative distribution of Herbst corpuscles in the oropharynx of these two commercially important ratite species may assist in a better understanding of their feeding habits. Tissue sections representing all parts of the oropharynx of five o...

19 The involvement of the calcium-sensing receptor (CaSR) in Ca homeostasis was investigated 20 in larval zebrafish, Danio rerio. The expression of CaSR mRNA was first observed at 3 h post21 fertilization (hpf) and increased with development until plateauing at about 48 hpf. At 4 days 22 post-fertilization (dpf), CaSR mRNA was increased in fish acclimated to low Ca water (25 μM 23 versus 250 μM...

1. The increase of conductivity produced by saponin in formaldehyde-hardened blood is due to an increase in the conductivity of the corpuscles (increased permeability of the corpuscles to ions) and not, mainly at any rate, to the liberation of electrolytes from the corpuscles and a consequent increase in the conductivity of the serum. The increase in the permeability of the corpuscles is probab...

Sickle cell anaemia is a type of haemoglobin disorder causing morbidity and mortality in many countries. The disease incurable therefore requires symptomatic management to improve quality life. Because the alternative system medicine can play significant role life sickle anaemia, lot combinations formulations are attempted across Unfortunately, very few have reached preclinical clinical researc...

Washed blood corpuscles of certain species of animals in a concentration of about (5) per cent suspended in salt solution containing above 4 per cent of cobra venom undergo changes in their resistance to certain physical and chemical agents. They become non-haemolyzable by water, ether, saponin, and quite strong solutions of lecithin, provided always that the excess of venom has not been entire...

Malachite green is an extensively used biocide in the aquaculture industry world-wide. It has been widely used due to lack of a proper alternative. Pyceze, however, is a pharmaceutical alternative to malachite green, with bronopol as its active ingredient. The catfish Heteropneustes fossilis were exposed for four days to 1/5th of LC50 values of each of malachite green (0.24mg/l) and Pyceze (0.4...
