Hemograms and acute-phase proteins in adult male New Zealand White rabbits that had been experimentally infected orally with sporulated oocysts of Eimeria stiedai were evaluated over a 28-day period. Fifty animals were used, divided into two groups: group A infected with 1 × 10(4) sporulated oocysts of E. stiedai and group B inoculated with distilled water. On the seventh day after infection, the infected animals presented anemia and leukocytosis with neutrophilia and monocytosis. Protein fractionation by means of electrophoresis identified 19 acute-phase proteins with molecular weights ranging from 24 to 238 kD. Ceruloplasmin, transferrin and haptoglobin showed high levels on the seventh day after infection, with gradual increases in their concentrations until the end of the experimental period. Thus, from the data of the present study, E. stiedai is considered to be a pyogenic etiological agent for which the infection level can be monitored through the leukocyte count and serum concentrations of ceruloplasmin, transferrin and haptoglobin, and these can be recommended as complementary tests.

Bioartificial bone tissue engineering is an increasingly popular technique to repair bone defect caused by injury or disease. This study aimed to investigate the feasibility of PLLA/PCL (poly-L-lactic acid/polycaprolactone) by a comparison study of PLLA/PCL and PLLA scaffolds applied in bone regeneration. Thirty healthy mature New Zealand rabbits on which 15 mm distal ulna defect model had been established were selected and then were divided into three groups randomly: group A (repaired with PLLA scaffold), group B (repaired with PLLA/PCL scaffold), and group C (no scaffold) to evaluate the bone-remodeling ability of the implants. Micro-CT examination revealed the prime bone regeneration ability of group B in three groups. Bone mineral density of surgical site in group B was higher than group A but lower than group C. Meanwhile, the bone regeneration in both groups A and B proceeded with signs of inflammation for the initial fast degradation of scaffolds. As a whole, PLLA/PCL scaffoldsin vivoinitially degrade fast and were better suited to repair bone defect than PLLA in New Zealand rabbits. Furthermore, for the low mineral density of new bone and rapid degradation of the scaffolds, more researches were necessary to optimize the composite for bone regeneration.

Abstract Introduction: The experiment was undertaken to estimate the effect of BMSCs seeding in different scaffold incorporation with HBO on the repair of seawater immersed bone defect. And future compared n-HA/PLGA with β-TCP/PLGA as scaffold in treatment effect of seawater immersed bone defect.Methods: 60 New Zealand White rabbits with standard seawater defect in radius were randomly divided to group A (implant with nothing), group B (implanted with atuogenous bone), group C (implanted with n-HA/PLGA/BMSCs, and Group D ( implanted with β-TCP/PLGA/BMSCs). After implant, each rabbit receive HBO treatment at 2.4 ATA 100% oxygen for 120 minutes per day for 2 weeeks. Radiograph, histological and biomechanical examination were used to analyze osteogenesis.Result: X-ray analysis show that n-HA/PLGA/BMSCs and β-TCP/PLGA/BMSCs could accelerate the new bone formation, and the new bone formation in group C was lager than in group D or group A, and close to group B (P<0.05). After 12 weeks, in group A, defect without scaffold show a loose connect tissue filled in the areas. The medullary canal in group B was recanalizated. Defect in group C and D show a larger number of wove bone formation. The new wove bone formation in defect areas in group C was lager than D. The mechanical examination revealed ultimate strength at 12 weeks were group D>group C>group B>group A(P<0.05).Conclusion: Scaffold of n-HA/PLGA and β-TCP/PLGA incorporation with HBO and BMSCs were effective to treat seawater immersed bone defect, and n-HA/PLGA was more excellent than β-TCP/PLGA.

Transmissible Venereal Tumour

Background: Canine transmissible venereal tumour (CTVT) also known as infectious sarcoma, venereal granuloma, transmissible lymphosarcoma or sticker tumour is usually transmitted through coitus and mainly affects the external genitalia of young sexually matured dogs. Surgery, chemotherapy, radiotherapy and immunotherapy are considered as effective treatment protocols. Therefore, depending upon the availability present study was designed to investigate the efficacy of different surgico-chemotherapeutic protocols for treatment of canine transmissible venereal tumour.Methods: The study was conducted during January 2018 to July 2018 at the Teaching Veterinary Clinical Complex (TVCC) and Department of Veterinary Surgery and Radiology, College of Veterinary Science and A.H., Anjora, Durg (C.G.) on 18 canines of various breed, irrespective of age, sex and divided into three groups consisting 6 animals in each group. Group A was treated with surgical excision of tumour only where as Group B and Group C were treated with surgical excision of tumour followed by administration of Doxorubicin (30mg/m2) BSA and Vincristine sulphate (0.025 mg/kg) intravenously alongwith DNS at 7th and 14th post-operative days respectively. Different physiological and haemato-biochemical parameters (Hb, PCV, TLC, TPC, DLC, serum glucose, TSP, SUN, SC, ALT, AST and ALP) were recorded preoperatively, postoperatively and after chemotherapy at 10th, 30th and 60th days intervals.Result: The present investigation showed transient changes in physiological and haemato-biochemical parameters before, post surgery and post chemotherapeutic management and was within normal range. Histopathological examination revealed confluent sheet of tumour cells arranged in large round oval or polyhedral shaped distributed in tight clusters or cords. Group A showed mild to moderated reoccurrence while Group B showed minimum reoccurrence. Group C showed no reoccurrence. Thus, surgery combined with vincristine therapy is most effective for treating dogs suffering with transmissible venereal tumour.

PURPOSE This pilot study of the Australia and New Zealand Childhood Cancer Study Group investigated the effectiveness and toxicity of a regimen incorporating vincristine (VCR), etoposide, and divided-dose, escalating cyclophosphamide (CPA) (VETOPEC) in 23 patients aged 1 to 20 years with solid tumors. PATIENTS AND METHODS Seventeen patients (group A) had recurrent or refractory tumors after prior multiagent therapy, and six patients (group B) with adverse prognostic indicators were treated at initial presentation. Treatment cycles were 21 to 28 days and consisted of vincristine (0.05 mg/kg) on days 1 and 14, with etoposide (2.5 mg/kg/d) plus escalating CPA on days 1, 2, and 3. The CPA dosage was escalated from 30 mg/kg/d in cycle no. 1 by 5 mg/kg/d in each cycle to a maximum of 55 mg/kg/d in cycle no. 6. RESULTS Of 20 patients assessable for tumor response, 19 (95%) responded after two to six cycles of VETOPEC: seven complete responses (CRs); eight very good partial responses (VGPRs); and four partial responses (PRs). In group A, 13 of 14 (93%) assessable patients responded (five CRs, four VGPRs, four PRs), and in group B, five stage IV and one stage III patient achieved two CRs and four VGPRs. The principal toxicity was myelosuppression. Grade IV neutropenia occurred after 98% of cycles, and the incidence of grade IV thrombocytopenia increased from 37% after cycle no. 1 to 91% after cycle no. 6 (P = .002). A total of 115 cycles delivered were followed by 62 febrile admissions (54%), and showed a significant rise with increasing cycles (P = .001). One patient died of septicemia. CONCLUSION This combination and scheduling produced a high response rate in patients with recurrent, refractory, or advanced solid tumors of childhood. Further studies of this regimen and of strategies to reduce hematologic toxicity are warranted.

Purpose: To evaluate changes in arterial wall mechanics induced by stent overdilation in the rabbit aorta. Methods: Twenty New Zealand white rabbits had initial stent deployment (3-mm × 8-mm Multilink) at 10% overdilation. Group A (n=11) had no subsequent balloon expansion of the stent and Group B (n=9) had 30% overdilation of the stent. A noninvasive B-mode ultrasound examination coupled with image processing allowed the measurement of systolic and diastolic diameter and the calculation of diameter compliance (Cd) and distensibility coefficient (DC) as indexes of arterial wall biomechanics. Measurements were performed before stenting in the infrarenal aorta, after initial stenting, and after stent overdilation at 3 locations: upstream, at the stent level, and downstream from the stent. Results: Cd was significantly lower in the stented aorta after initial stenting (p<0.0001) and after stent overdilation (p<0.0001) than before stenting. At the stent level, Cd and DC were significantly lower than downstream (p<0.0001) or upstream (p<0.0001) from the stent after initial stenting, as well as after stent overdilation. Downstream from the stent, Cd and DC were significantly lower after stent overdilation than before stenting (p<0.05). Conclusions: Endovascular stenting of the rabbit aorta produces a significant decrease in arterial wall compliance and distensibility. Stent overdilation is responsible for a slight additional decrease of compliance downstream from the stent.

Abstract Objective: to study the differences in calcium-phosphorus and vitamin D metabolism in healthy individuals with deficient and sufficient baseline state of vitamin D. Materials and methods: The study included 16 young conditionally healthy individuals, divided into two equal groups: with levels of 25(OH)D below and above 30 ng/ml determined by the immunochemiluminescent method (Group A and Group B respectively; DEQAS certified). All participants were evaluated for the biochemical parameters of blood and urine, characterizing calcium-phosphorus metabolism, PTH by commercial methods, and vitamin D metabolites (25(OH)D3, 25(OH)D2, 3-epi-25(OH)D3 and 24,25(OH)2D3) by HPLC/MS-MS before oral intake of 150 000 IU of an aqueous solution of cholecalciferol and 7 days after administration. Results: At baseline, the level of vitamin D metabolite 25(OH)D2 in Group B was lower with no significant differences in other studied parameters. In group A, strong positive correlations were observed between levels 25(OH)D3 and 3-epi-25(OH)D3, 24,25(OH)2D3, while in group B there were no such associations. After taking a loading dose of cholecalciferol, the groups showed generally similar changes in the studied vitamin D metabolites: a statistically significant increase in 25(OH)D3, 3-epi-25(OH)D3, a decrease in 25(OH)D2, and a ratio of 24,25(OH)2D3 to 25(OH)D3. However, the level of 24,25(OH)2D3 did not change in group B, with a significant increase in group A. The medians of the studied biochemical parameters in blood/urine, as well as PTH, remained unchanged in both groups. Conclusion: In patients with inadequate baseline levels of 25(OH)D, after a loading dose of cholecalciferol, there is a tendency to formation of more inactive forms of vitamin D. These deviations in the metabolism of vitamin D need to be clarified, since they can potentially affect the effectiveness of cholecalciferol therapy.

Aim: The aim of this study was to evaluate the effects of three commonly marketed herbal cosmetics in Port Harcourt on the renal parameters in rabbits. Study Design:  This study is an experimental study. Place and Duration of Study: This study was carried out at Animal House, Applied and Environmental Biology Department, Rivers State University, Port Harcourt, Rivers State, Nigeria, between April 2020 and November 2020. Methodology: A total of 48 rabbits were used for the study. They were divided into four groups with twelve rabbits in each group. Four rabbits from each group were treated for thirty, sixty and ninety days respectively. All the rabbits were given feed and tap water ad-libitum. Using the Organisation for Economic Co-operation and Development (OECD) guideline for volume selection, 0.5ml/kg of Samples A, B, C and D were each applied to 5cm by 5cm scrapped dermal Forsa of the rabbits in each group every morning for the respective treatment periods stated above. At days thirty, sixty and ninety, respectively, four rabbits from each group were sacrificed under chloroform anaesthesia. Blood samples were collected from the rabbits at intervals, 30days, 60days and 90days. The kidneys were harvested at 90 days from the rabbits. The blood was collected to test sodium, potassium, chloride, calcium, urea, creatinine, KIM-1 and kidney for histological analysis. GraphPad Prism v.7.0 was used for statistical analysis and p values less than 0.05 were considered statistically significant. Results: The results showed that Potassium level was significantly higher (p<.05) from day 30 for group A compared to control, group B and group C. This is attributed to group A having a higher level of cadmium and arsenic compared to the other groups.  The urea and creatinine result for group A was significantly higher by day 30 (p<.05) compared to control with group B and group C. Whereas calcium became significantly lower at day 60. With chloride significantly higher (p<.05) at day 60. Early signs of toxicity to the Kidney were identified from the significant effect on the urea, creatinine, KIM-1 and histology results. The continued use of these products contaminated by these heavy metals will release them slowly into the body of recipients and which will invariably damage the kidney. Conclusion: The continued use of these products contaminated by these heavy metals will release them slowly into the body of recipients and which will invariably damage the kidney. Early signs of toxicity to the Kidney were identified from the significant effect on the urea, creatinine, KIM-1 and histology results.

The current study was planned to assess the different oxidative, Endocrinological and biochemical parameters using extract of Catharanthus roseus (C. roseus) on diabetic rats. Three groups of Diabetic rats were assigned viz. Group A have Negative Control which was fed basal diet; Group B have Positive Control and was non-supplemented; and Group C supplemented with C. roseus extract. The results showed that blood glucose level, ALT, TGs and urea concentration was elevated non-significantly (P>0.05), of Group C which was supplemented by C. roseus when compared with non-supplemented Group B animals. In Group C which was supplemented by C. roseus, AST, and Cholesterol results were decreased as showed by statistics analysis (non-significantly). When level of Blood cortisol was compared between Group C and B, there was increased in Group C, as per non-significant statistics measurements (P>0.05). It was observed that level of T4 and T3 hormones was decreased in Group C (supplemented by herbal extract) when compared with Group B. When catalase enzyme results were checked in animals comprised of Group A, B and C, it showed that rate of catalase increased, respectively. In conclusion, Catharanthus roseus restore the levels of thyroid hormones, and cholesterol; and elevate catalase enzyme activity in animals which produce stress relieving effect.

Aim: This study was aimed at evaluating the protective role of different local spices on lambda cyhalothrin induced nephrotoxicity in male mice Experimental Design: A completely randomized experimental design using standard methods for analysis. Place and Duration of Study: This study was carried out in the Animal house, Department of Animal and Environmental Biology of Rivers State University, Nkpolu-Oroworukwo Port Harcourt, Nigeria. GPS 4o47'50''N 6o58'49''E. This study lasted for 35days. Methodology: The experimental animals were separated into 6 groups (A-F) of seven mice each. Group A served as the control and Group B – F served as the test groups. At the end of the 35 day treatment period, feed was withdrawn from the mice 24 hours before termination of the experiment. Blood samples for analysis of kidney function test were collected from each mouse by ocular puncture into plain tubes. The blood was allowed to clot and centrifuged at 2500g to separate the serum from the cells. Total protein was analyzed using the spectrophotometric method of biuret, Bradford and erythrosine – b, albumin was estimated, creatinine and urea was done using enzymatic method. Vital organs were removed and weighed for organosomatic indices. Histological sections of the kidney were mounted on slides, stained with hematoxylin and eosin (H&E). Photomicrographs were generated. Results: There is no significant difference (P=0.05) between the organ weight and bodyweight in group A compared with the treatment groups. The values of Albumin, total protein, urea, creatinine and total bilirubin increased significantly in group B administered lambda cyhalothrin alone but decreased in groups administered the local spices. Histopathological analysis of the kidney shows the regular structure of the kidney architecture in group A, tubular degeneration and several vacuolations were observed in group B. However, less degeneration of the epithelial cells, regeneration of renal tubular epithelium were observed in groups C- F. Conclusion: Based on the results from liver biomarkers and histological micrographs from this study, pronounced degeneration was observed in the kidney cells exposed to lambda-cyhalothrin only. Moreover, all spices used had a regenerating ability on the kidney tubules. It is advocated therefore that consumption of this spices either singly or in combination should be encouraged especially for those exposed to insecticides poisoning
