“…The biology of freshwater mussels viz., Parreysia corrugata Lomte 1971, Lomte andJadhav 1980) Parreysia favidens (Ramesha and Sophia 2015) and Lamellidens spp. (Narian 1972, Nagabhushanam and Lohgaonker 1978, Moorthy et al 1983 inhabiting in the freshwater habitat have been reported previously. However, no data are available on growth pattern of freshwater mussels L. marginalis from Bangladesh.…”

Growth, morphometry and length-weight relationships of the freshwater mussel Lamellidens marginalis (Lamarck, 1819) was studied during January 2014 and May 2015. Sampling was carried out monthly and a total of 560 specimens were collected from Rajshahi district, northwest of Bangladesh. The recorded length -breadth and length-width relationships were B = 0.179 + 0.475L and W = 0.196 + 0.3163L respectively. The length-total weight, length-wet tissue weight, length-dry tissue weight, length-shell weight, length-dry shell weight relationships were W = 0.1241L2.9066, W = 0.0524L2.7377, W =0.0116L2.7849, W = 0.0533L2.9178 and W = 0.0391L3.0386 respectively. Monthly b values of length-lengths and length-weights relationships indicated a negative allometric growth pattern except length-shell weights relationships which showed an isometric growth of the mussel. This study is the first report on growth pattern of Lamellidens marginalis from Bangladesh and the results would be useful for fishery managers to impose adequate regulations for a sustainable fishery management of this species in the freshwater ecosystem in Bangladesh.

“…The decrease in succinate dehydrogenase (SDH) activity due to oxidative stress condition indicates reduction in the conversion of succinate to fumarate resulting in depressed in oxidative metabolism mitochondria. During the diabetic stress condition diversion of phosphoenolpyruvate leads to increased formation of fumarate resulting in product inhibition of SDH (Moorthy et al, 1983), the decrease in the activities of SDH in tissues of diabetic rats can be associated with enzyme dysfunction due to activation of lipid peroxidation. In diabetic rats Pimpinella tirupatiensis treatment SDH activity was increased when compared to diabetic rats.…”

The objective of the present study was to investigate the role of Pimpinella tirupatiensis (Pt) aqueous extract on brain mitochondrial enzymes in Streptozotocin (STZ) induced diabetic rats. Adult male wistar strain rats were divided into five groups as NC (normal control), Pt. (Pimpinella treatment), DC (Diabetic control), D+Pt (Diabetic+ Pimpinella treatment), D+Gli (Diabetic + Glibenclamide treatment). Treatment was given as per the experimental protocol for 30days. Succinate dehydrogenase (SDH), glucose-6-phosphate dehydrogenase (G6PD), malate dehydrogenase (MDH),and glutamate dehydrogenase (GDH), and lactae dehydrogenase (LDH) enzymes activities were assayed in the brain tissue. In diabetic rats, we observed decreased activities of SDH, G6PDH, MDH, GDH and increased LDH activity. However with the Pimpinella tirupatiensis treatment mitochondrial enzymes activities were came back to normalcy. Our results suggest that the Pt supplementation modulates the mitochondrial enzymes activities in diabetic rats.

“…Since glycogen storage and mobilization is restricted to certain tissues, alterations in glycogen concentrations observed are often tissue specific. In mussels, the hepatopancreas and mantle are the primary storage organs for glycogen and generally the first to be utilized (Bayne, 1973), although under stressful conditions mobilization from other tissues such as foot muscle can also occur (Moorthy et al, 1983).…”

The ultimate goal of toxicity testing is to monitor or predict the effects of single compounds, elements or mixtures on the long-term health of individual organisms, populations, communities and ecosystems. Unfortunately, one does not always have all of the information required to determine the long-term or 'chronic' effects of toxicants on the survival, growth or reproduction of aquatic organisms. For this reason, the chronic effects of toxicants are often inferred or estimated from observations made during short-term or 'acute' field or laboratory studies, which may be conducted at greater concentrations of toxicant. The observations made in the short-term studies are then related to the chronic effects by some statistical relationship. There are basically two approaches: 1)The long-term effects on a parameter, such as survival (lethality) are predicted from observations on the same parameter, during short-term exposures; 2) Alternatively, the response of one parameter to long-term exposures of a toxicant can be predicted from the short-term responses of a different parameter. In this report we present several different examples of both types of methods for estimating chronic responses from information on more short-term responses and discuss the rationale, advantages and disadvantages of each. We also report on two biochemical indicators; energetic substrates and RNA/DNA ratio. These indicators both act as sensitive, integrative measures of sublethal effects of contaminants during both acute and chronic exposures.
