The Relationship

To quantify the relationship between both regional and overall diaphragm morphometry and body weight in the dog, diaphragm thickness was measured in five regions of the costal diaphragm and three regions of the crural diaphragm in 40 healthy dogs (8-40 kg). Surface area of the diaphragm, diaphragm weight, and body weight were also determined. Diaphragm surface area and weight varied linearly with body weight, but there was no significant correlation between overall diaphragm thickness and body weight. Diaphragm thickness varied significantly between regions, and three regions had systematic left-to-right differences as well. Because diaphragm geometry influences the diaphragm's function as a pressure generator, regional differences in thickness may alter the relationship between the force developed by the activation of a particular region of the diaphragm and its action on the respiratory system.

Cacing yang digunakan sebanyak 258 individu yang terdiri atas 190 immature, 54 submature dan 14 mature dengan ukuran panjang tubuh rata-rata berturut-turut 108,62±34,80 mm, 172,27±42,78 mm dan 123,14±57,40 mm. Cacing betina ditemukan memiliki ukuran tubuh lebih besar dari jantan. Panjang tubuh N. abiuma dapat diduga dengan bobot tubuh, panjang L3 dan lebar S-10 dengan nilai koefisien korelasi (r) berturut-turut 0,82, 0,73 dan 0,78. Pendekatan morfometri dapat digunakan untuk menentukan ukuran tubuh N. abiuma.Abstract The short nypa palm worm Namalycastis abiuma has an elastic and fragile body. Therefore, an alternative approach of morphometrical techniques is needed to determine the total body length. This research aimed to estimate the total body length of the short nypa palm worm based on body weight, the total number of segments, the length of the first three anterior segment (L3) and the tenth setiger width (S10). Body measurement was done using stereomicroscope fitted with the micrometer. Correlation analysis was done to describe the relationship between the length of L3 and the width of S10. A total of 258 complete and whole specimens consisted of 190 immature, 54 submature, and 14 mature individuals. The average body length of immature individuals was 108.62±34.80 mm, 172.27±42.78 mm for sub mature individuals, and 123.14±57.40 mm for mature individuals. Based on sexual dimorphism, the female body size is larger than male. The body length of N. abiuma can be estimated by body weight, the length of L3, and the  width of S10, with  correlation coefficient (r) of 0.82, 0.73 and 0.78, respectively. Morphometry approach can be used to determine the body size of N. abiuma.

The exotic barb Puntius gonionotus was introduced into Bangladesh in 1987. Its faster growth rate, nice taste and compatibility with our culturable species have made it very popular food fish in Bangladesh. With a view to providing some basic information towards development of sustainable seed production of the species, a study was undertaken to determine the fecundity and ovary characteristics of the fish. The mean fecundity of 55 gravid females (of 11 length group) of Puntius gonionotus was obtained as 14321 with a range of 2254.67 to 6964.73 from fishes having a mean total length and mean body weight of 200.13±20.58 mm and 196±34.379 g respectively. The relationship between the fecundity (F) and total length (TL), total body weight (TW), ovary length (OL) and ovary weight (OW) were established. Regression analysis was made and the co-efficient of correlation (r) was calculated for each of the following F-TL, F-TW, F-OL and F-OW and the values of r were obtained to be 0.84, 0.84, 0.95 and 0.96 respectively. In all the cases linear relationships obtained were highly significant. Key words: Fecundity, Puntius gonionotus, ovarian characteristics. J. bio-sci. 14: 99-102, 2006

Turnover of transferrin was measured in 62 mammals from 11 species (baboon, dog, goat, guinea pig, man, mouse, pig, rabbit, rat, rhesus monkey, and sheep) using iodinelabeled transferrin of homologous and/or heterologous origin. Protein turnover was determined either from the plasma protein-bound radioactivity curves or from the slopes of total body radiation. The volume of transferrin pool, expressed as equivalent milliliters of plasma, turned over per day correlated closely with species size (r = +0.977). Using the parabolic equation, y = axb, the constants for the relationship between body weight (x) and transferrin turnover (y) were a, 22.845; and b, 0.68. However, species of comparable weights with deviating transferrin turnovers do exist within the boundaries of this relationship. From a limited number of serum transferrin estimations in all species except for rhesus, six species appeared to have transferrin concentrations in a broad middle range (2.5-3.5 mg/ml). By comparison, dog and guinea pig had markedly lower, and pig and rat had markedly higher, serum transferrin concentrations.

Haem Iron

1. Total body iron and some of its subfractions, i.e. haem iron, non-haem iron and ferritin iron, as well as ferritin were measured in groups of newborn rats and of rats aged 4,15 and 24 d.2. Iron accumulated in the rats throughout suckling, with slightly more going into the haem than into the non-haem fraction.3. Per unit body-weight, haem iron was maintained well throughout the study period but total body iron and non-haem iron were both significantly diminished at 15 d.4. Within the non-haem fraction, ferritin iron was severely diminished at both 15 and 24 d, but the non-ferritin portion of non-haem iron was increased.5. The results were interpreted in terms of the relationship between the growth of body mass and the supply of iron to the young animal.

The Relationship

1. The oxygen consumption and surface area of individual diploid and triploid prepupae of Drosophila melanogaster have been measured, the cells of triploid animals being larger. 2. The mean weights for the types examined are different but their ranges overlap almost completely. By covariance analysis it is shown that, after adjustment for difference in body size, there are no differences in the rates of oxygen consumption. It is concluded that, for these animals, cell size has no influence on the rate of oxygen consumption. 3. The relationships between body weight, surface area, and oxygen consumption have been further investigated. It is shown that, despite the greater inaccuracy of the method by which surface area is determined, oxygen consumption can be predicted more accurately from surface area than from body weight. 4. The results are discussed in relation to an earlier investigation of the oxygen consumption of other genotypes (Ellenby, 1945 a, b). Possible technical causes of certain differences between the two series of results in the relationship of oxygen consumption and body weight are explored; it is concluded, however, that they are almost certainly due to differences, not necessarily genetical, between the animals used in the two series.

Objective This study aimed to compare the correlations between KTN and creatinine clearance (Ccr) calculated by different methods and to determine and compare the correlations between KTN and Ccr. Design Nonrandomized, retrospective analysis of data. Setting Continuous ambulatory peritoneal dialysis (CAPD) outpatient clinic in a teaching hospital. Patients All patients were included for analysis if the data collection was complete for the calculations of KTN and Ccr using five different methods. Interventions Volume of distribution for urea (V) was estimated by four methods: Watson nomogram, ideal body weight (IBW), actual body weight, and total body surface area. Ccr was determined by five methods: Dialysate Ccr was calculated by creatinine (Cr) uncorrected and corrected for the presence of glucose; urinary Ccr was calculated using urinary Cr alone and the average urinary clearance of urea and Cr; and by the Cockcroft and Gault method. Main Outcome Measures Correlations between KTN and Ccr. Results Sixty-three data sets were collected from 52 CAPD patients. The correlations between weekly KTN and Ccr normalized to 1.73 m2 body surface area were found to be highly variable from one method to another (r2 = 0.012 -0.494). For obese patients (20% above IBW), KTN values obtained were more variable using the Watson nomogram compared to the IBW and BSA methods. Conclusion KT/V calculated using the Watson nomogram and the Ccr determined using average of urinary urea and creatinine clearance gave the best correlation (r2 = 0.49).
