A study was conducted to observe the breeding performance and nursery practices of the threatened indigenous fish species Labeo bata in Jessore (Longitude: 89°122 003 East; Latitude: 23°102 453 North), Bangladesh during 1998 to 2002. Eight trial doses of PG (Pituitary Gland) used for induced breeding of L. bata were 1.0mgPG/kg in the first dose, and 1.0 to 8.0mgPG/kg in second dose for female. On the other hand, five trial doses were administered for the male to identify the suitable single dose (1.5mgPG/kg) only. The best performance was obtained with 5.0mg of PG/kg body weight in the second dose for female of wild and successive three generations. The highest growth (lt.: 19.37mm and wt.: 57.67mg) and survivability (63.33%) of the fish fry was observed by using rice bran and mustard oil cake after 10 days of nursing.

An experiment on the induced breeding of the endangered fish, Labeo calbasu (Hamilton-Buchanam) was conducted in the Fish Seed Multiplication Farm,Rajshahi to know the efficacy of two inducing agents (PG and DoM+SGnRH). Three breeding trials of each inducing agent were performed. A total of 24 females weighing from 1.5 kg to 2 kg were given an initial and a resolving dose of 1.5 mg and 6 mg PG extract per kg body weight respectively as treatment-1. On the other hand, a total of 24 females weighing from 1.5 kg to 2 kg were given a single dose of 12 mg DoM + SGnRH/kg as treatment-2. In case of treatment-1, 12 males weighing from 1.5 kg to 1.95 kg were administered a single dose of 1.5 mg PG/kg body weight during resolving dose of female. In treatment-2, 12 males weighing from 1.5 kg to 1.8 kg were administered 3 mg DoM+SGnRH /kg body weight during initial dose of females. In treatment-1, the time interval between initial and resolving dose was 5 hours and ovulation occurred in all the injected females within 6 hours after resolving dose. Ovulation occurred within 6 to 8 hours after the injection of inducing agents for treatment-2. The mean rates of ovulation, fertilization and hatching were 100%, 77.36% and 74.5% respectively in treatment-1. On the contrary, the mean rates of ovulation, fertilization and hatching were 83.33%, 63.83% and 59.66% in treatment-2. Hatchery produced fry were reared in nursery pond for 40 days. In nursery pond. Flour, oil cake and wheat bran were applied as nursery feeds. Both the inducing agents were effective in respect of overall breeding performance. But the best results were obtained with PG although in case of DoM+SGnRH complete breeding takes place within short time with less labour and cost than that of PG.DOI: http://dx.doi.org/10.3329/ujzru.v31i0.15376Univ. j. zool.

ABSTRACT: The objective of this study was to describe the epidemiological, clinical, and pathological aspects of Palicourea aeneofusca poisoning in cattle in the region of Pernambuco, Brazil and to determine if it is possible to induce food aversion by P. aeneofusca poisoning in cattle raised under extensive management conditions. To determine the occurrence of poisoning, 30 properties were visited in five municipalities of the region of Pernambuco. Three outbreaks of poisoning of cattle were monitored. To induce conditioned food aversion by the consumption of P. aeneofusca, 12 animals were randomly distributed into two groups of six animals each. Cattle were weighed and received green P. aeneofusca leaves in their trough at a dose of 35mg kg-1 body weight for spontaneous consumption. The control group (CG) animals received water (1ml kg-1 body weight) via a feeding tube after the first ingestion of the plant, while the other animals, constituting the aversion test group (ATG), underwent induced aversion with lithium chloride (LiCl - 175mg kg-1 body weight) via a feeding tube. For the ATG cattle, the aversion to P. aeneofusca induced by a single dose of LiCl persisted for 12 months. In contrast, the CG animals continued to consume the plant in all tests performed, indicating the absence of aversion. This study showed that aversive conditioning using LiCl was effective in preventing poisoning by P. aeneofusca for a period of at least 12 months.

1. Cisplatin [6 mg/kg body weight, in 0.9% (w/v) NaCl] was injected intraperitoneally as a single dose to two groups of rats (Fischer 344 strain). Two further groups of rats, injected intraperitoneally with an equivalent volume of 0.9% (w/v) NaCl, were used as controls. The cisplatin-treated rats developed a pronounced polyuria which did not recover during an 18 week observation period. 2. After 21 weeks, one group of the cisplatin-treated animals received a 6 h infusion of 2.5% d-glucose. Vasopressin (60 μ-units min−1 100 g−1 body weight) was incorporated into the infusate for the final 2 h. A control group of animals received an identical infusion. One week later the other group of cisplatin-treated rats received a 6 h infusion of 0.9% (w/v) NaCl. Indomethacin was incorporated into the infusate for 15 min, at 3 h 52.5 min, to deliver a dose of 10 mg/kg body weight. A control group again received an identical infusion. 3. Cisplatin did not impair the antidiuretic effect of vasopressin, but it reduced the natriuretic effect of vasopressin, and also impaired the ability of the animals to produce concentrated urine. 4. Cisplatin did not alter basal PGE2 excretion, or the reduction in PGE2 excretion induced by indomethacin. However, the urine flow in the cisplatin-treated group did not fall after indomethacin, whereas there was a fall in urine flow in the control group.

Abdominal Irradiation

Previous studies have demonstrated that abdominal irradiation alters intestinal uptake of nutrients. The purpose of this study was to determine the effect of an orally administered synthetic prostaglandin E2, enprostil, given on three occasions shortly prior to a single exposure to 600 cGy external abdominal irradiation, on intestinal active and passive transport processes and villus morphology measured 7 days later. Animals were sham-irradiated (CONT) or were exposed to a single dose of 600 cGy external abdominal irradiation (RAD); two and one mornings before the day of irradiation or sham irradiation, and 1 h before irradiation or sham irradiation enprostil was administered. One half of CONT and RAD groups were dosed orally with enprostil, 5 μg/kg body weight, and the other half of the CONT and RAD groups were dosed with placebo. Seven days later the in vitro uptake of glucose, galactose, long-chain fatty acids, and cholesterol was determined in the four groups (CONT with and without enprostil, and RAD with and without enprostil). In CONT, enprostil was associated with increased jejunal uptake of glucose and ileal uptake of galactose. In RAD given enprostil, there was increased jejunal uptake of galactose but reduced ileal uptake of glucose and galactose. The expected radiation-associated decline in jejunal galactose uptake was prevented with enprostil. In CONT given enprostil, there was increased jejunal uptake of fatty acid (FA) 14:0 and 16:0 but reduced uptake of FA 18:0, 18:1, and 18:2; enprostil had no effect on lipid uptake in the ileum in CONT. Enprostil had a different effect in RAD, with reduced jejunal uptake of FA 14:0; 16:0, 18:0, 18:3, and cholesterol and reduced ileal uptake of FA 16:0, 18:1, 18:2, 18:3, and cholesterol. Enprostil was associated with a reduced jejunal mucosal surface area in CONT and a reduced ileal mucosal surface area in RAD. The irradiation-associated decline in body weight was not observed in animals given enprostil despite the lack of change in food intake. The alterations in nutrient uptake were not due to differences in food intake, weight change, or mucosal surface area. Thus, enprostil given on three occasions just before a single dose of abdominal irradiation was associated with increased intestinal uptake of galactose, but failed to prevent most of the other irradiation-associated changes in active and passive intestinal transport, and accentuated rather than prevented the irradiation-associated diminution in mucosal surface area.Key words: adaptation, cholesterol, fatty acids, galactose, glucose, ileum, jejunum.

The present research work was conducted to develop a balanced ration for crossbred high yielding calves in farm condition. For this purpose, seventy days long feeding trial was conducted with nine crossbred female calves having nearly similar body weight and age. Nine crossbred calves were equally divided into three groups such as T1 (1 kg concentrate mixture of crushed maize, wheat bran, mustard oil cake, molasses, DCP and salt at a ratio of 25:45:22:5:1:2, respectively), T2 (1 kg concentrate mixture of crushed maize, wheat bran, soybean cake, molasses, DCP and salt at a ratio of 27:45:20:5:1:2, respectively) and T3 (Wheat bran, rice polish, mustard oil cake, DCP, Salt were supplied according to BAU routine farm feeding at a ratio of 65:18:14:1:2, respectively). All calves were supplied with ad libitum green grasses (German and Para) and fresh clean drinking water. From the research finding, it was observed that the average total dry matter intake, total body weight gain, body length gain and heart girth gain were in T1 (2.68a±0.000 kg, 2.51a±0.21 kg, 1.83a±0.12 cm, 1.29a±0.07 cm, respectively) and T2 (2.65a±0.001 kg, 2.55a±0.21 kg, 1.67a±0.12 cm, 1.25a±0.07 cm, respectively) groups significantly (p<0.05) higher than that of the T3 (2.34b±0.002 kg, 0.96b±0.21 kg, 0.81b±0.12 cm, 0.64b±0.07 cm, respectively) group. The result showed that the body weight gain of T2 group was higher by supplementation of balanced ration. Therefore, the feed supplementation of crushed maize, wheat bran, soybean cake, molasses, DCP and salt at a ratio of 27:45:20:5:1:2, respectively should be supplied to crossbred calves for the future development of dairy herd replacement stock for profitable dairy business.

A field trial was conducted to examine effects of substrates on yield of carp and SIS at Sukranagar Village, Chitwan district for 210 days in farmer’s pond. The experiment was designed with four treatments: T1 (carp only), T2 (carp+SIS), T3 (carp+substrate) and T4 (carp+SIS+substrate) with four replicates. Ponds were stocked with fingerlings of six carp species at a rate of 20,000 fish/ha and two Small indigenous fish species at a rate of 50,000 fish/ha in 1:1 ratio. Prior to stocking of fish, split bamboo mats were fixed in substrate ponds covering 2% of pond surface area to enhance periphyton growth. Carp were fed with dough of rice bran and mustard oil cake (1:1) at the rate of 3% BW daily while Grass carp was fed with grass and banana leaves at 50% BW. Growth and yield of Rohu and Common carp, combined net fish yield and gross margin were found higher (p<0.05) in carp ponds with substrate.

This study was undertaken to investigate the bioavailability of various L-carnitine esters (acetyl-L-carnitine and lauroyl-L-carnitine) and salts (L-carnitine L-tartrate, L-carnitine fumarate, L-carnitine magnesium citrate) relative to base of free L-carnitine. Six groups of five or six piglets each were administered orally a single dose of 40 mg L-carnitine equivalents/kg body weight of each of those L-carnitine compounds. A seventh group served as a control. Free and total plasma carnitine concentrations were determined 1, 2, 3.5, 7, 24, and 32 hours after administration of the single dose. Area-under-the-curve (AUC) values were calculated to assess the bioavailability of the L-carnitine compounds. AUC values, calculated for the time interval between 0 and 32 hours, for both free and total carnitine were similar for base of free L-carnitine and the three L-carnitine salts (L-carnitine L-tartrate, L-carnitine fumarate, L-carnitine magnesium citrate) while those of the two esters (acetyl-L-carnitine, lauroyl-L-carnitine) were lower. Administration of L-carnitine L-tartrate yielded a higher plasma free carnitine AUC value for the time interval between 0 and 3.5 hours than administration of the other compounds. The data of this study suggest that L-carnitine salts have a similar bioavailability to that of free L-carnitine while L-carnitine esters have a lower one. The study also suggests that L-carnitine L-tartrate is absorbed faster than the other L-carnitine compounds.

In order to assess the effect of adding Dedhuwa (Esomus danricus), Mara (Amblyparyngodon mola) and Pothi (Puntius sophore) on Carp production, an experiment was carried out in farmers’ pond in Chitwan. The experiment included four treatments in triplicates: T1, (Carp: Silver carp, Hypophthalmychthys molitrix, Bighead carp, Aristichthys nobilis, Rohu, Labeo rohita and Mrigal, Cirrhinus mrigala), T2 (Carp+Dedhuwa), T3 (Carp+Mara), and T4 (Carp+Pothi). Fish were fed on dough of rice bran and mustard oil cake (1:1) at the rate of 3% of body weight. Results showed that Dedhuwa, Mara and Pothi did not differ significantly (P>0.05) in terms of production. Production of Silver carp and Bighead carp was found significantly higher (P<0.05) in T3 and T4 than control indicating no niche overlapping among these fish. Based on total production and profit T4 appeared to be best.DOI: http://dx.doi.org/10.3126/on.v9i1.5741

Summary14 patients (5 diabetics with arteriosclerotic complications, 4 patients with thrombo-embolic disease, 4 with cirrhosis, coagulation defects and increased fibrinolytic activity, and 1 cancer patient) and 3 control patients were subjected to turnover studies with 13iodine labelled human fibrinogen.Half-life times in the control patients were found to be 4 days, the fractional turnover rates 19–23 per cent, of intravascular fibrinogen per day, and the absolute turnover 0.02 to 0.06 gm per day per kg. body weight. The other patient’s half-life times and turnover rates varied considerably from 0.9–5.5 days, 13–160 per cent, per day of intravascular fibrinogen and 0.02–0.4 gm per day per kg. body weight respectively.As fibrinogen unlike other proteins subjected to turnover studies, is converted to fibrin, it is not possible to measure the true intra-extravascular distribution ratio of fibrinogen. But intravascular fibrinogen could be approximated to constitute 68–99 per cent, of the total fibrinogen. There is justification in believing that fibrinogen is degradated through a continuous coagulation in equilibrium with fibrinolysis, and that the organism contains a greater mass of fibrin, the “fibrin pool”. Considerations of the turnover mechanism can however only be hypothetical.
