    Notes: Abstract The disposition kinetics and appropriate dosage regimen for kanamycin were investigated in buffalo calves following a single intravenous dose of 10 mg/kg body weight. The distribution and elimination half-lives were 0.12±0.01 h and 1.94±0.11 h, respectively. The apparent volume of distribution and total body clearance were 0.2±0.01 L/kg and 92.9±3.69 ml/kg/h, respectively. About 74% of the administered dose was excreted in urine in 24 h. A suitable dosage regimen for the intravenous administration of kanamycin was also calculated.

    Notes: Abstract The pharmacokinetics, penetration into erythrocytes and plasma protein binding of cefotaxime were investigated in cross-bred calves. Following a single intramuscular dose of cefotaxime (10 mg/kg), the absorption half-life and elimination half-life were 0.13±0.03 h and 2.97±0.72 h, respectively. The apparent volume of distribution and total body clearance were 3.28±0.72 L/kg and 0.78±0.08 L/kg per h, respectively. The extent of penetration into erythrocytes was 24–40% of the total blood concentration. Cefotaxime was bound to plasma proteins of calves to the extent of 25.5–33.6%. A satisfactory intramuscular dosage regimen for cefotaxime in calves would be 11 mg/kg followed by 10 mg/kg at 7 h intervals.

    Notes: Abstract Seed Protein Concentrates (SPC) of 6 species ofCrotalaria were extracted and the extractabilities of SPC, total N and protein N determined. SPC of high yielding species (C. juncea) was analysed for the contents of amino acids, ash, phosphorus, sugar, starch, fibre and calories, as well as forin vitro digestibility. Results indicate the promising potential ofC. juncea for SPC yield.

    Notes: Abstract Seed protein concentrates (SPC) were extracted from 4 leguminous species and the extractabilities of total N (nitrogen), protein N and SPC determined. In addition, composition, calorie value andin vitro enzymatic digestibility of these SPCs was analysed. Results indicate the promising nutritional potential of these SPCs.

    Notes: Abstract β-Picolinium-p-chlorophenacylide (β-PCFY) acts as a retarder for polymerization of N-vinyl pyrrolidone. The polymerization runs were carried out at 60°C using benzene as an inert solvent. The kinetic equation for the present system may be written asR p α[β-PCPY]−1.0 [AIBN]0.66[N-VP]1.0. The value of overall energy of activation for polymerization in presence and absence ofβ-PCPY was computed as 44.0 and 42.3 kJ mol−1, respectively. The inverse relationship ofR p and¯M v withβ-PCPY suggests thatβ-PCPY acts as a polymerization retarder. The retarding effect is also evidenced by higher initiator exponent value and higher value of energy of activation in presence of ylide. A mechanism is also proposed in which polymer propagating chain combines with one ylide component to give resonance stabilized radical.

    Notes: Radical copolymerization of zinc acrylate (ZnA2) with acrylonitrile (AN), initiated by As2S3-styrene complex(I), in dimethyl Sulphoxide (DMSO) at 90 ± 0.1°C for 1.0h under inert atmosphere, yields non-alternating copolymers. The kinetic expression is Rp ∝ [I]0.33 [ZnA2]0.25 [AN]0.44, i.e. the system follows non-ideal kinetics, which is due to primary radical termination as well as degradative chain transfer reactions. The values for activation energy (E) and k2p/kt are 128kJ mol-1 and 8.57 × 10-7 litre mol-1 s-1, respectively. Thermal stability, solubility in different solvents, and IR and NMR spectra have been evaluated.
