Pleomorphism of Lysosomes

  Pleomorphism of Lysosomes Lysosomes show pleomorphism, which means they occur in many different forms according to their functional state. They are not always identical in shape, size, or contents. Their appearance changes depending on whether they are newly formed, involved in digestion, or storing undigested waste materials.  Lysosomes are membrane-bound organelles containing hydrolytic enzymes. These enzymes digest proteins, lipids, carbohydrates, nucleic acids, and other cellular materials. Since lysosomes perform different digestive functions inside the cell, they appear in different structural forms. This property is called pleomorphism.  The main pleomorphic forms of lysosomes are primary lysosomes, secondary lysosomes, autophagic vacuoles, and residual bodies. Primary lysosomes are newly formed lysosomes produced by the Golgi apparatus. They contain inactive hydrolytic enzymes and have not yet taken part in digestion. They are small, spherical vesicles surround...

Evaluation of Antioxidant and Antidiabetic activity of White Oyster Mushroom (Pleurotus florida) cultivated in North Bengal

  Evaluation of Antioxidant and Antidiabetic activity of White Oyster Mushroom ( Pleurotus   florida ) cultivated in  North Bengal Abstract: Oyster mushroom is one of the popular mushrooms cultivated in North Bengal.  Pleurotus florida  is one of the cultivated mushroom having high demand for its bright white colour, texture and good taste. Seasonal productivity of  P. florida  was estimated and it was observed that the production rate is higher in late rainy season to winter season as the fruiting body required moderately low temperature. Antioxidant activity of  P. florida  also evaluated in respect of DPPH scavenging activity and Free reducing antioxidant power (FRAP) activity which showed significant results.  In vivo  antidiabetic activity was also evaluated in using Streptozotocin induced albino rats and it was observed that the mushroom powder helps in lowering the blood glucose level and actively regain the body weight....
