چکیده
The physico-chemical characteristics, lipids, protein, fat, moisture and ash of P. globosa and L.luteola were studied. The percentage of oil content found were 2.30 ± 0.29 and 1.61 ± 0.12 in meat of P. globosa and L. luteola. The protein and fat content of P. globosa were 33.81% and 1.80% whereas 22.71% and 1.49% in L. luteola. The moisture content were 75.31% and 78.96% in P. globosa and L. luteola respectively. The total lipid extracts were fractionated into three major lipid groups neutral lipids, glycolipids and phospholipids by silicic acid column chromatography. The glycolipid were averaged to 57.39% and 57.24% of the weight of the lipid applied in L. luteola and P. globosa. The percentage composition of fatty acids were found in the form of oleic 19.46 ± 0.33, lauric 13.23 ± 0.73, palmitic 16.56 ± 0.41 in L. luteola and 20.37 ±1.38, 14.30 ± 1.06 and 18.52 ± 1.10 in P. globosa respectively.

Storage excretion in the Indian apple snail, Pila globosa (Swainson), during aestivation.
Uric acid accumulates in several tissues of the Indian apple snail, P. globosa, during aestivation. This accumulation is particularly high in the foot muscle and reproductive organs. Since the kidney, a tiny organ in the snail, has only a limited capacity to store uric acid, extrarenal tissues are used as storage depots of uric acid during aestivation. It is suggested that the aestivating snail...
متن کاملMolluscicidal effect of nicotinanilide and its intermediate compounds against a freshwater snail Lymnaea luteola, the vector of animal schistosomiasis.
The molluscicidal effect of nicotinanilide was evaluated and compared with niclosamide (2',5-dichloro-4'-nitrosalicylanilide, ethanolamide salt) against different stages of the freshwater snail Lymnaea luteola i.e., eggs, immature, young mature, and adults. Calculated values of lethal concentrations (LC50 and LC90) showed that both nicotinanilide and niclosamide as toxic against eggs, immature,...

The present study was conducted to investigate the prevalence of developmental stages of Fasciola gigantica infection in Lymnaea snails and their populations in Sylhet region of Bangladesh. A total of 1865 Lymnaea snails were collected and examined, of which 56 (3%) were found to having infected with developmental stages of Fasciola gigantica. Only 4.08% infected of 515 snails were collected fr...
