Progressive chorion morphology during egg development in Samia ricini (Donovan).

Abstract: The egg of Samia ricini (Donovan), is oval or laterally flattened ellipsoid, freshly laid eggs are candid white while the chorion is colorless and semi-transparent. The surface of the chorion is covered with network patterns of polygons and their shapes are common in the whole surface region. The boundaries between polygons made ridges had distinct acropyles at three-cell junctions. The numbers of aeropyles are variable according to their structures both in the lateral flat and marginal regions. During the course of egg development, no significant structural changes were observed in either the polygonal structures or the overall morphology of the egg. However, the size of the aeropyles kept on changing as the egg matures. The aeropyle increases initially upto day-9 of egg development and then decreases as it approach hatching. Lines of weaknesses were not observed at time of hatching or close to it. Hatching process of the newly emerge larvae are through gnawing. The larva eats their way out through the chorion membrane mostly from the anterior region. Egg buster or spine which aid in hatching are not present in the newly emerge larvae.This article was published online on 25 September 2009. An error was subsequently identified.

Diabetics of Northeast India are at risk of dietary zinc and manganese deficiency: possible improvement through consumption of some traditional edibles or edibles of limited popularity.

Abstract: Background: Restricted diets of Northeast India were found to be low in both zinc and manganese. Aim: To explore the possibilities of compensating for the low zinc and manganese content in restricted diet by supplementing with traditional edibles and edibles of limited popularity. Materials and Method: Concentration of these two elements in a number of edibles from Northeast India was assessed along with some traditional edibles and edibles of limited popularity. Results: Relatively high concentration of zinc and manganese were recorded in some traditional edibles and edibles of limited popularity, which when added to diabetic diet could elevate the concentration of zinc and manganese, and bring the level of these two elements close to the recommended level. Conclusion: It is suggested that, the deficiency of essential elements in the restricted diet of diabetics in Northeast India should be monitored and appropriate supplementation may be tried, preferably through some traditional edibles and edibles of limited popularity.
