Plasmapheresis

 Plasmapheresis

- Souti Das



 In this experiment, the dog is rendered hypoproteinaemic by repeatedly withdrawing whole blood and injecting back the cellular elements of the blood (suspended in Ringer-Locke solution). This process is repeated daily till the level of plasma proteins fails to 4g/100 ml. Thereafter different standard diets are given and their effects on protein synthesis are studied. Following conclusions have been drawn from this experiment:

• Dietary proteins are essential for synthesis of plasma proteins.

• Chemical resemblance of food protein amino acid with those of the plasma proteins to be synthesized determines their efficacy to synthesize a particular protein.

• Essential amino acid must be present in the diet for the satisfactory synthesis of plasma proteins.

• Dietary proteins of animal origin favours albumin synthesis.

• Dietary proteins of plant origin favours globulin synthesis.

• Regeneration of plasma proteins occurs within 14 days.

• Rate of regeneration of plasma protein is very fast within first 24 hours.

Process of lactation/lactogenesis

 Process of lactation/lactogenesis - Souti Das To provide milk to neonates, at the end of pregnancy around the time when the young is born, the mammary glands undergo a process that initiates milk secretion, called lactogenesis. The human mammary gland is composed of about 20 lobes, each with an excretory lactiferous duct that opens at the nipple. Loves, in turn, are composed of several lobules, which contains secretory structures called alveoli, and the terminal portions of the ducts. The epithelia of the alveoli and ducts are composed of apical luminal ductal or alveolar cells and a myoepithelial cell layer on the basal side of the epithelium. Myoepithelial cells are stellate, smooth muscle-like cells, and contraction of these cells in response to oxytocin expel milk from the lumina of the alveoli and ducts.

Fertilization In Sea Urchin (CSIR NET Developmental Biology)

Fertilization In Sea Urchin - Malay Nayak 1.        What is sea urchin? ·          Spiny water animal ·          Phylum ECHINODERMATA ·          Roughly spherical sea animal Sea Urchin   2. Why Sea Urchin ? The cell-surface events that take place during fertilization have been studied most extensively in sea urchins, members of the phylum Echinodermata . ·    Sea urchin gametes are easy to collect, ·    fertilization occurs outside the animal body. ·    As a result, researchers can observe fertilization and subsequent development simply by combining eggs and sperm in seawater in the laboratory.
