Abstract
The objective of this study was to evaluate the effectiveness of common antibiotics against different microorganisms in apparently healthy cattle in Shandong province and its suburb. A total of 220 nasal swab samples were collected and cultured for bacteriological evaluation. All the bacteria isolates after preliminary identification were subjected to antibiogram studies following disc diffusion method. It was found in the study that E. coli is the most commonly associated isolate (21%), followed by Klebsiella spp. (18%), Pseudomonas aeruginosa (13%), Salmonella spp. (15%), Shigella spp (12%), and Proteus spp (11%). While the antibiogram studies reveled that highest number of bacterial isolates showed resistance to Ampicillin (95%), followed by Augmentin (91%), Cefuroxime (85%) and Tetracycline (95%) of (Escherichia coli and Klebsiella spp). In the case of pseudomonas spp. and Salmonella the highest resistance was showed by Ampicillin (90%) followed by Amoxicillin + Clavulanic Acid (80%), Cefixime (90%), and Erythromycin (80%). In Shigella spp and Salmonella spp highest resistance was showed by Amoxicillin, Ceftazidime, Augmentin (60%), and Amoxicillin + Clavulanic Acid (50%). It is concluded that in vitro antibiogram studies of bacterial isolates revealed higher resistance for Ampicillin, Augmentin, Cefuroxime, Cefixime, Tetracycline, Erythromycin, and Amoxicillin + Clavulanic Acid. The high multiple Antibiotics resistance indexes (MARI) observed in all the isolates in this study ranging from 0.6 to 0.9. MARI value of >0.2 is suggests multiple antibiotic resistant bacteria and indicate presence of highly resistant bacteria.

Abstract
BACKGROUND We aimed to investigate the prevalence of Aloe Vera gel extract and antibiotic resistance against in Escherichia coli, Shigella, Salmonella spp and Staphylococcus aureus were isolated from animal's skin infection. OBJECTIVE The purpose of this study was has been designed to check the antibacterial effect of Aloe Vera against some common skin pathogens, and its comparison to commonly used antibiotics, with the aim to provide the cheap source of medication. MATERIAL AND METHODS We performed a prospective study to determine 150 Skin infections were isolates obtained from septic wounds with sterile cotton swab at different Animal and applied to freshly prepared slants of nutrient agar, Mannitol Salt agar (Oxoid), and further conformation Catalase and a coagulase test were performed for biochemical characterization. We used Skin wound isolates were subjected to antibiotic resistance and Aloe Vera gel screening by disk diffusion method. RESULT Four bacterial spp. strains were isolated from 150 skin infection of animals, the prevalence of organisms were found positive for Escherichia coli, Shigella, Salmonella Spp and Staphylococcus aureus respectively. Antibiotic resistance and susceptibility pattern of above isolates was also studies against 10 different clinically significant antibiotics. Aloe Vera leave gels were extracted with four different solvent were used during research. This result showed that ethanol extracts of Aloe Vera both leaf and root can be used alongside conventional antibiotics to fight agents of infections that are so prevalent in the skin infection. CONCLUSION This investigation further assures that the plant extracts could be used for the treatment of microbial infections, our present findings we recommended that Aloe Vera gel at optimum concentration could be used as an antiseptic for prevention of some microbial skin wound infections. It is believed that this study could be used to identify new and more potent antimicrobial drugs of natural origin.

Abstract
A comparative study on pharmacokinetics of four long-acting enrofloxacin injectable formulations was investigated in 36 healthy pigs after intramuscular injection according to the recommended single dose @ 2.5 mg/kg body weight. The drug concentrations in the plasma were computed using high-performance liquid chromatography (HPLC) with fluorescence detection. WinNonLin5.2.1 software was used to analyze the experimental data and compared it under one-way ANOVA using SPSS software with a 95% confidence interval (CI). The main pharmacokinetic parameters, that is, the maximum plasma concentrations (Cmax), the time to maximum concentration (Tmax), area under the time curve concentration (AUCall) and Terminal half-life (T1/2) were 733.84 ± 129.87, 917.00 ± 240.13, 694.84 ± 163.49, 621.98 ± 227.25 ng/ml, 2.19 ± 0.0.66, 1.50 ± 0.37, 2.89 ± 0.24, 0.34 ± 0.13 h, 7754.43 ± 2887.16, 8084.11 ± 1543.98, 7369.42 ± 2334.99, 4194.10 ± 1186.62 ng h/ml, 10.48 ± 2.72, 10.37 ± 2.38, 10.20 ± 2.81, and 10.61 ± 0.86 h for 10% enrofloxacin (Alkali), 20% enrofloxacin (Acidic), Yangkang and control drug Nuokang® respectively. There were significant differences among Cmax, Tmax, and AUCall of three formulations compare with that of the reference formulation. No significant differences were observed among the T1/2 for tested formulations compare with the reference formulation. The pharmacokinetic parameters showed that the tested formulations were somewhat better compared to the reference one. The calculated PK/PD indices were effective for bacteria such as Actinobacillus pleuropneumoniae and Pasteurella multocida with values higher than the cut-off points (Cmax/MIC90≥10–12 and AUC/MIC90 ≥ 125). However, they were not effective against bacteria like Haemophilus parasuis, Streptococcus suis, E. coli, and Bordetella bronchiseptica where lower values were obtained.

Abstract
Microencapsulation is a process where very minute droplets or particles of solid or liquid or gas are trapped with a polymer to isolate the internal core material from external environmental hazards. Microencapsulation is applied mostly for flavor masking, fortification, and sustained and control release. It improves palatability, absorption, and bioavailability of drugs with good conformity. Microencapsulation has been widely studied in numerous drug delivery systems for human health. The application of microcapsules in the veterinary pharmaceutical sciences is increasing day by day. The treatment systems for humans and animals are likely to be similar, but more complex in the veterinary field due to the diversity of the species, breeds, body size, biotransformation rate, and other factors associated with animal physiology. Commercially viable, economically profitable, and therapeutically effective microencapsulated vaccine, anthelmintic, antibacterial, and other therapeutics have a great demand for livestock and poultry production. Nowadays, researchers emphasize the controlled and sustained-release dosage form of drugs in the veterinary field. This paper has highlighted the microencapsulation materials, preparation techniques, characteristics, roles, and the application of microcapsules in veterinary medicine.

Abstract
This study was carried out in the department of Neurosurgery, Dhaka Medical College Hospital, Dhaka, Bangladesh, during the period of January 2003 to December 2006 to elucidate the effectiveness of surgical treatment in the management of low grade astrocytoma of brain. For this purpose, a total number of 50 cases admitted during the study period with low grade astrocytoma of brain supported by clinical features and radiological investigations (CT and MRI scan) were included in this study. The mean age of the patient was a 27.3+/-16.9 year ranging from 1.8 to 65.0 years. Males (64.0%) were more in comparison to females (36.0%) with a male female ratio of 1.8:1. The main presenting complaints were headache (100%), convulsion (84.0%), vomiting (80.0%), visual impairment (20.0%), motor deficit (16.0%) and ataxia (14.0%). All cases had a definite diagnostic investigation at the time of admission. Plain x-ray skull was done in all patients followed by CT scan (70%), MRI scan (60%) and both CT and MRI scan (64.0%). Out of 50 patients 60.0% had gross total removal of tumor and 40.0% sub total tumor resection. Histopathological study was done in all cases after tumor resection. Among the gross total tumor removal cases highest percentage had good recovery (93.4%) in the immediate post operative period. Only one (3.3%) patient developed severe disability and equal percentage had moderate disability. Another 2(4.0%), those underwent subtotal tumor resection died during subsequent follow up period at 8th and 14th postoperative day.
