Abstract
The presence of one or more pesticides in a variety of mediums is responsible for their indirect toxicological events leading to cell senescence. In the present investigation, the endeavor was made to see the effect of pesticides Car- Benda-Zim (CBZ) and IMIdacloprid (IMI) alone and in combination with bone marrow-derived Mesenchymal Stem Cells (bMSCs) of buffalo origin. Isolated and cultured bMSCs were exposed to CBZ and IMI alone and in combinations at lower doses. Cells were observed for alterations in cell morphology, oxidative stress, mitochondrial damage and cellular senescence. bMSCs characterized for stem cell surface markers and found to be positive for AP, CD73 and OCT4. bMSCs exposed to IC25, IC12.5 and IC6.25 CBZ and IMI alone and combinations of IC12.5 and IC6.25 of CBZ and IMI. Results revealed significant reduction (p?0.05) in cell viability noticed on microscopic examination along with loss of normal cell morphology and increased in Reactive Oxygen Species (ROS) positive cells, cells with loss of ??m and number of senescent cells in CBZ and IMI treated groups. Lower dose combination groups showed elevated effects when compared with higher dose alone treated groups and control groups. Present findings suggest that CBZ and IMI induced cytotoxicity in bMSCs mediated via ROS production, altered ??m leading to the cell damage and predisposing senescence process. Moreover, the co-existence of CBZ and IMI in a medium has a considerably more toxic effect than their individual effect.

Abstract
The single dose pharmacokinetics (PK) of marbofloxacin was compared with repeated intravenous (IV) administrations in six healthy goats at the dose rate of 2 mg/kg body weight at 24 h interval for 5 days. Blood samples were collected at times: 5, 15, 30 min and 1, 2, 4, 6, 9, 12, 24, 36, 48 and 72 h post drug administration. Plasma drug concentrations were determined by High Performance Liquid Chromatography and concentration-time data were subjected to non-compartment analysis. The MIC and MBC of marbofloxacin against Escherichia (E.) coli and Pasteurella (P.) multocida in Mueller Hinton Broth were determined by broth microdilution method. The t1/2elm = 4.37 ± 0.18 h and ClB = 0.29 ± 0.01 following single administration were not significantly different from t1/2elm = 5.11 ± 0.22 h and ClB = 0.26 ± 0.01 mL/kg/h after repeated administrations of marbofloxacin. Accumulation index (AI = 1.1) indicated no accumulation of marbofloxacin following repeated IV administrations up to 5 days. The respective MICs of marbofloxacin against E. coli and P. multocida were 0.03 μg/mL and 0.4 μg/mL. The AUC0-24h/MIC ratios were 226.64 ± 7.21 h for E. coli and 16.99 ± 0.541 h for P. multocida. PK/PD integration indicated that marbofloxacin daily dose of 2 mg/kg is appropriate for treating E. coli (MIC ≤ 0.03 μg/mL) infections. However, a higher dose of 6 mg/kg/day is suggested to obtain clinical cure against diseases caused by P. multocida having MIC90 = 0.12 μg/mL in goat species.

Abstract
The objective of this study was to investigate the pharmacokinetics of cefquinome following single intramuscular (IM) administration in six healthy male buffalo calves. Cefquinome was administered intramuscularly (2 mg/kg bodyweight) and blood samples were collected prior to drug administration and up to 24 hr after injection. No adverse effects or changes were observed after the IM injection of cefquinome. Plasma concentrations of cefquinome were determined by high-performance liquid chromatography. The disposition of plasma cefquinome is characterized by a mono-compartmental open model. The pharmacokinetic parameters after IM administration (mean ± SE) were Cmax 6.93 ± 0.58 μg/ml, Tmax 0.5 hr, t½kα 0.16 ± 0.05 hr, t½β 3.73 ± 0.10 hr, and AUC 28.40 ± 1.30 μg hr/ml after IM administration. A dosage regimen of 2 mg/kg bodyweight at 24-hr interval following IM injection of cefquinome would maintain the plasma levels required to be effective against the bacterial pathogens with MIC values ≤0.39 μg/ml. The suggested dosage regimen of cefquinome has to be validated in the disease models before recommending for clinical use in buffalo calves.

Abstract
Larval packet test was used for detection of resistance levels against cypermethrin and deltamethrin, the most commonly used synthetic pyrethroids, in the multi-host tick Hyalomma anatolicum collected from district Moga, Punjab (India). Results indicated the presence of level I resistance against deltamethrin (RF = 2.81), whereas the tick isolate was susceptible to cypermethrin (RF = 0.2). The aqueous and ethanolic extracts of leaves of Cymbopogon winterianus, Vitex negundo and Withania somnifera along with roots of Vitex negundo were assessed for their acaricidal activity against the larvae of deltamethrin resistant H. anatolicum. The efficacy was assessed by measuring per cent larval mortality and determination of LC50 values. The various ethanolic extracts produced a concentration dependent increase in larval tick mortality, whereas the aqueous extracts exhibited a much lower mortality. The highest mortality (93.7 ± 0.66 %) was observed at the 5.0 % concentration of ethanolic extract of leaves of C. winterianus and the lowest LC50 value (0.011 %) was recorded for ethanolic extracts of leaves of V. negundo. The results indicated that these plant extracts have potential to be developed as herbal acaricides.

Abstract
The pharmacokinetics and urinary excretion of gatifloxacin were investigated after a single intravenous injection of 4 mg/kg body weight in buffalo calves. The therapeutic plasma drug concentration was maintained for up to 12 h. Gatifloxacin rapidly distributed from blood to tissue compartments, which was evident from the high values of the distribution rate constant, alpha1 (11.1 +/- 1.06 h(-1)) and the rate constant of transfer of drug from central to peripheral compartment, k12 (6.29 +/- 0.46 h(-1)). The area under the plasma drug concentration-time curve and apparent volume of distribution were 17.1 +/- 0.63 (microg.h)/ml and 3.56 +/- 0.95 L/kg, respectively. The elimination half-life (t (1/2 beta)), total body clearance (ClB) and the ratio of drug present in tissues and plasma (T/P) were 10.4 +/- 2.47 h, 235.1 +/- 8.47 ml/(kg.h) and 10.1 +/- 2.25, respectively. About 19.7% of the administered drug was excreted in urine within 24 h. A satisfactory intravenous dosage regimen for gatifloxacin in buffalo calves would be 5.3 mg/kg at 24 h intervals.

Abstract
The disposition kinetics and urinary excretion of pefloxacin after a single intravenous administration of 5 mg/kg were investigated in crossbred calves and an appropriate dosage regimen was calculated. At 1 min after injection, the concentration of pefloxacin in the plasma was 18.95 +/- 0.892 microg/ml, which declined to 0.13 +/- 0.02 microg/ml at 10 h. The pefloxacin was rapidly distributed from the blood to the tissue compartment as shown by the high values for the initial distribution coefficient, alpha (12.1 +/- 1.21 h-1) and the constant for the rate of transfer of drug from the central to the peripheral compartment, K12 (8.49 +/- 0.99 h ). The elimination half-life and volume of distribution were 2.21+/- 0.111 h and 1.44 +/- 0.084 L/kg, respectively. The total body clearance (ClB) and the ratio of the drug present in the peripheral to that in the central compartment (P/C ratio) were 0.454 +/- 0.026 L/kg h) and 5.52 +/- 0.519, respectively. On the basis of the pharmacokinetic parameters obtained in the present study, an appropriate intravenous dosage regimen for pefloxacin in cattle for most of the bacteria sensitive to it would be 6.4 mg/kg repeated at 12 h intervals.

Abstract
Possible central modulation of acute peripheral inflammation by putative amino acid neurotransmitters was investigated in rats by adopting formalin induced pedal inflammation as an experimental model. Out of five amino acids (GABA, glycine, DL-alanine, L-glutamic acid and L-aspartic acid) tested, intracerebroventricular (icv) administration of GABA and L-aspartic acid produced significant alteration in acute inflammation. GABA showed a significant attenuation of paw oedema and nociception whereas, L-aspartic acid produced significant increase in oedema volume along with marked hyperalgesia. In conclusion, the study confirms that CNS is capable of modulating peripheral inflammation.

Abstract
The possibility of central noradrenergic and dopaminergic modulation of Brewer's yeast-induced peripheral inflammation was investigated in rats. Centrally administered noradrenaline (NA), amphetamine, which liberates NA and dopamine in the central nervous system and L-dopa, the precursor of dopamine significantly suppressed paw oedema. Conversely, the beta-adrenoceptor blocker, propranolol, catecholaminergic neuron degenerator, 6-hydroxydopamine (6-OHDA), dopaminergic antagonist, haloperidol and dopamine synthesis inhibitor, alpha-methyl para tyrosine (AMPT) augmented paw oedema. In addition, 6-OHDA and haloperidol produced significant reduction in pain threshold. The results of this study indicate that central NA and dopamine exert inhibitory effects on Brewer's yeast-induced peripheral inflammation.

Abstract
Possible central serotonergic and histaminergic modulation of acute peripheral inflammation was investigated in rats, adopting the formaldehyde-induced acute pedal inflammation as an experimental model. Intracerebroventricular (icv) administration of central inhibitory neurotransmitter, serotonin and its precursor, 5-hydroxytryptophan (5-HTP) attenuated the oedema volume and exudate protein content alongwith augmentation in pain threshold. On the contrary, cyproheptadine, a 5-HT-receptor antagonist and selective serotonin synthesis inhibitor, parachlorophenylalanine (PCPA) produced oedema augmenting and pro-nociceptive effects besides elevating the protein content of the exudate. Centrally administered histamine attenuated pedal oedema, nociception as well as protein concentration in oedema fluid. Cimetidine, an H2 histaminergic receptor blocker did not produce any significant effect on inflammation.

Abstract
Possible central noradrenergic and cholinergic modulation of acute peripheral inflammation was investigated in rats, adopting the formaldehyde-induced pedal inflammation as the experimental model. Intracerebroventricularly (icv) administered noradrenaline (NA), alpha-adrenoceptor agonist, L-phenylephrine, alpha-2 adrenoceptor agonist, clonidine and non-selective beta-adrenoceptor blocker, propranolol, suppressed formaldehyde-induced inflammation producing a decrease in oedema volume and increase in pain threshold. Conversely, both noradrenergic neuron degenerator, 6-hydroxydopamine (6-OHDA) and non-selective alpha-adrenoceptor antagonist, phenoxybenzamine produced an increase in paw oedema along with an augmentation of pain. Significant oedema augmenting effects were also produced by central excitatory neurotransmitter, acetylcholine (ACh) on icv administration. ACh also produced pro-nociceptive action. An ACh antagonist, scopolamine and ACh synthesis inhibitor, hemicholinium-3 (HC) reduced pedal oedema and produced analgesia. The results of this study indicate that central NA exerts an inhibitory effect on peripheral oedema and pain whereas, ACh has an augmenting effect on formaldehyde-induced peripheral inflammation.
