Compost Science and Utilization | Year: 2010

The feasibility of mixing sandy soil with manure compost was explored for growing muskmelon (Cucumis melon L.). Eight combinations of two compost types (cattle manure with straw (CS) and sheep manure with straw (SS)) mixed in different ratios to sandy soil were used. The mineralisation rate of N and P in CS substrates was higher than that in SS substrates. The reverse was the case for K. The yield and quality of fruit was higher in CS than in SS substrates. CS substrates were therefore better than SS substrates and the optimum rate of addition was a 1:1 ratio of compost to sandy soil.

This study investigated the haematological and blood biochemical characteristics of Glyptosternum maculatum. The haematological and biochemical parameters were measured in 30 adult fish collected from Nyingchi Reach of Yarlung Zangbo River in Tibet. The red blood cell count (RBC), haemoglobin concentration (Hb), haematocrit (Hct), erythrocyte osmotic fragility (maxEof and minEof), the erythrocyte sedimentation rate, mean cell volume (MCV), mean cellular haemoglobin content (MCH), and mean cell haemoglobin concentration (MCHC) were determined. Compared with other Siluriformes fishes, G. maculatum showed similar mean values for Hct, Hb, MCH, and MCHC and had slightly lower RBC and higher MCV. The biochemical parameters were assayed including alanine aminotransferase, aspartate aminotransferase (AST), alkaline phosphatase, total protein, albumin, globulin, albumin/globulin ratio, total bilirubin, direct bilirubin, urea, creatinine, glucose, total cholesterol, and triglyceride. The result showed that the value of AST in G. maculatum was obviously higher than that in Rhamdia quelen as well as in Silurus merdionalis. © 2009 Springer Science+Business Media B.V.

The peripheral blood cells of a sisorid catfish Glyptosternum maculatum were studied using light microscope and transmission electron microscope. The size of cells and nucleus, and the percentage of different leucocytes were also described. Erythrocytes and four types of leucocytes: lymphocytes, heterophils, monocytes, and thrombocytes were characterized in G. maculatum blood. The dividing erythrocytes could be found sporadically. A plasma cell was observed under a transmission electron microscope. The morphology and structure of blood cells of G. maculatum were basically similar to those of other fish species, although there were also main differences, such as larger erythrocytes than other catfishes, absence of basophils and acidophils, and various types of thrombocytes (five types: lone nucleus, fusiform, tadpole-like, oval, and in a cluster). © 2010 Springer Science+Business Media B.V.
