Individual housing has been reported to modify animal behaviour. The present study compares the plasma levels of glucose, triglycerides and total cholesterol, weight, and food and water intake in two groups of female rats. Group A: 10 rats who remained grouped in two cages for 21 days; and Group B: 10 rats housed in two cages for 7 days, then isolated in individual cages from day 8 to day 15, and finally grouped together again for the last 7 days of the study. The results showed that the plasma values of glucose declined ( P<0.05) in the Group B rats when they had been returned to group condition (4.79±0.72 mM) than when they had been isolated (5.45±0.94 mM). Plasma triglyceride levels were lower ( P<0.05) in isolated rats (0.70±0.26 mM) than in any determination of the grouped rats. Group B: 1st week 1.21±0.21 mM, 3rd week 0.88±0.20 mM; and Group A: 1.22±0.20, 0.96±0.16, and 0.96±0.36 mM, in the first, second, and third week, respectively. There were no statistically significant differences in total cholesterol values as a function of the individual housing of animals. While there was no weight difference between the two groups of rats that could be ascribed to individual housing, there was a statistically significant increase ( P<0.05) in the food intake of isolated rats (17.5±3.2 g) with respect to values in the same Group B animals when they were housed together (1st week, 16.6±2.8 g; 3rd week, 16.8±3.1 g). These results therefore confirm that individual housing of female rats provoke variations in certain biochemical parameters, and that if this is not taken into account in performing different scientific studies, it could give rise to unreliable or even dubious results.

Aim: The study was conducted to observe the effects of dexamethasone (DEX) on the gross study and histomorphometry of liver and on the alterations of biochemical parameters of broilers. Materials and Methods: Ninety day-old chicks were collected and assigned to one of three groups: The control, Group A, and Group B. The control, Group A, and Group B were fed for 28 days with a homemade ration, a commercial broiler type ration, and a homemade ration with DEX (7 mg/kg feed), respectively. Liver samples were collected from the individual birds after sacrificing on days 7, 14, 21, and 28 of the experiment. Morphometric characteristics (length, weight, color, and texture) of the liver were examined. Histomorphological alterations of the liver were assessed with routine hematoxylin and eosin staining. To measure the biochemical parameters, blood samples were collected on days 7, 14, 21, and 28 of the experiment. Liver function test was performed spectrophotometrically by analyzing serum biochemical markers, that is, alanine aminotransferase (ALT), aspartate aminotransferase, and alkaline phosphatase (ALP). Thin-layer chromatography (TLC) was performed for the detection of hepatic steroids. Results: Hemorrhagic and congested livers were found in broilers of Group B. There were no significant changes found in weight and length of the livers; only numerical decrease in weight and length was observed in birds of Group B. Liver width was increased in Group B on day 21. Histological observation of livers showed accumulation of lipid droplets, congestion of the sinusoids, and central veins in broilers of Group B. Biochemical analyses showed increased levels of ALT in Group B as compared to Group A on day 14 of the experiment. TLC evaluation revealed a positive result in Group B on 28 days of the experiment. Conclusion: The present study results show that DEX may alter the liver morphology and the concentration of ALT in the circulation of broilers.

This work focusses on comparative determination of the effects of plant extracts: bitter leaf (BL), sour lime (SL), grape (G), pawpaw (PP) and unripe pineapple (UPA) in female rats induced into malaria with Plasmodium berghei. Thirty female rats weighing 120-160 g were allotted into five groups (n=6). Group A (negative control) were infected but not treated. Animals in Groups B–E which were infected were given 500 mg/kg body weight (BW) of malanter DS (reference antimalarial drug), 500 mg/kg BW of BL, 250 mg/kg BW each of SL and BL as well as 250 mg/kg BW each of G, PP and UPA. Treatment was done orally once daily for 14 days after which a few related analyses were carried out. Before treatment, parasitemia count of animals in groups B-E was substantially (p<0.05) higher when juxtaposed with group A. AST and ALT activities was substantively (p<0.05) elevated in group B-E when matched with group A. Plasmodium berghei induction notably (p<0.05) lowered white blood cell (WBC) and monocyte (Mono) levels at all groups. After 7 days of treatment, the extracts and drug which appreciably (p<0.05) lowered plasmodium count, RBC, WBC, PCV, Hb, Plat, Lymph, Mono, Granul levels did not meaningfully (p>0.05) affect the activities of ALP, AST and ALT. After 14 days of treatment, the extracts and drug exceptionally (p<0.05) reduced plasmodium count, WBC and ALP activity at all groups. These results give suggestive evidence that the plant extracts either singly or combined, could be a promising anti-plasmodial candidate.

Exposure of sheep to Borreliaburgdorferi sensulato (s.I.) complex, the causative agent of Lyme borreliosis (LB), has been reported in tick-abundant areas worldwide, while no data have been reported in Greece. The aim of the study was to identify the hematological alterations in sheep with seropositivity against Borrelia burgdorferi (s.I.). Blood samples were obtained from 318 tick infested sheep for blood analysis and serological determination of IgG and IgM antibodies against B. burgdorferi by indirect immunofluorescence antibody (IFA) assay after exclusion of endo-ectoparasites and other tick-borne infections. A total number of 162 sheep met the inclusion criteria, allocated in four groups based on the presence or absence of IgG and/or IgM; sheep found negative for IgM and IgG (Group A), positive for IgM (Group B), positive for both IgM and IgG (Group C) and positive for IgG (Group D). Anemia, thrombocytopenia and normal or decreased leukocyte count, mainly due to lymphopenia were the main hematological features observed in seropositive sheep. The presence of these features raises the suspicion of Borrelia infection in tick infested sheep. The seropositivity of 23.58% in sheep raises concerns of Borrelia circulation, especially in rural areas and potential risk of transmission to humans.

Abstract Background This study aims at determining the biological effect of 75/25 w/w nano-hydroxyapatite/chitosan (nHAp/CS) scaffolds on bone regeneration, in terms of fraction of bone regeneration (FBR), total number of osteocytes (Ost), and osteocyte cell density (CD), as well as its biodegradability. Methods Two critical-size defects (CSDs) were bilaterally trephined in the parietal bone of 36 adult Sprague-Dawley rats (18 males and 18 females); the left remained empty (group A), while the right CSD was filled with nHAp/CS scaffold (group B). Two female rats died postoperatively. Twelve, 11, and 11 rats were euthanized at 2, 4, and 8 weeks post-surgery, respectively. Subsequently, 34 specimens were resected containing both CSDs. Histological and histomorphometric analyses were performed to determine the FBR, calculated as [the sum of areas of newly formed bone in lateral and central regions of interest (ROIs)]/area of the original defect, as well as the Ost and the CD (Ost/mm2) in each ROI of both groups (A and B). Moreover, biodegradability of the nHAp/CS scaffolds was estimated via the surface area of the biomaterial (BmA) in the 2nd, 4th, and 8th week post-surgery. Results The FBR of group B increased significantly from 2nd to 8th week compared to group A (P = 0.009). Both the mean CD and the mean Ost values of group B increased compared to group A (P = 0.004 and P < 0.05 respectively). Moreover, the mean value of BmA decreased from 2nd to 8th week (P = 0.001). Conclusions Based on histological and histomorphometric results, we support that 75/25 w/w nHAp/CS scaffolds provide an effective space for new bone formation.

Objective: Determination of the clinical effectiveness of ciprofloxacin versus ceftriaxone in children with enteric fever on the basis of defervescence within 72 hours of commencement of treatment. Duration and Place of Study: This randomized controlled trial was carried out from 15th May to 15th November 2017 in pediatrics units of Benazir Bhutto Shaheed Teaching Hospital Abbottabad and Jinnah International Hospital Abbottabad. Methodology: 90 children with uncomplicated enteric fever were admitted and divided randomly into two groups, Group A was administered I/V Ceftriaxone 75mg/kg OD and Group B was given I/V Ciprofloxacin 10mg/kg BD for seven days. Response to drug was taken as defervescence within 72 hours while continued fever after 72 hours was taken as no response. The data was analyzed by using SPSS Version 21.00. Results: In our research study 53(58.9%) children were male and 37(41.1%) patients were female. The mean age was 8.43±3.17 years encompassing 4 to 14 years, mean weight of the patients in kg was 29.54±10.8 kg. Efficacy of ceftriaxone group was 93.3% while in ciprofloxacin group 62.2% patients became afebrile in 72 hours. The proportion of achieving defervescence within 72 hours was higher with ceftriaxone than with ciprofloxacin Conclusion: Ceftriaxone is more efficacious in terms of achieving defervescence than ciprofloxacin in children having enteric fever.

Background: There is extreme heterogeneity in the available literature on the determination of R1 resection rate after pancreatoduodenectomy (PD); consequently, its prognostic role is still debated. The aims of this multicenter randomized study were to evaluate the effect of sampling and clearance definition in determining R1 rate after PD for periampullary cancer and to assess the prognostic role of R1 resection. Methods: PD specimens were randomized to Leeds Pathology Protocol (LEEPP) (group A) or the conventional method adopted before the study (group B). R1 rate was determined by adopting 0- and 1-mm clearance; the association between R1, local recurrence (LR) and overall survival (OS) was also evaluated. Results. One-hundred-sixty-eight PD specimens were included. With 0 mm clearance, R1 rate was 26.2% and 20.2% for groups A and B, respectively; with 1 mm, R1 rate was 60.7% and 57.1%, respectively (p > 0.05). Only in group A was R1 found to be a significant prognostic factor: at 0 mm, median OS was 36 and 20 months for R0 and R1, respectively, while at 1 mm, median OS was not reached and 30 months. At multivariate analysis, R1 resection was found to be a significant prognostic factor independent of clearance definition only in the case of the adoption of LEEPP. Conclusions. The 1 mm clearance is the most effective factor in determining the R1 rate after PD. However, the pathological method is crucial to accurately evaluate its prognostic role: only R1 resections obtained with the adoption of LEEPP seem to significantly affect prognosis.

Introduction: Rheumatoid arthritis is one of the most common systemic inflammatory diseases characterized by progressive damage to the joints. There is rising evidence that Renin Angiotensin Aldosterone System signaling is also involved in the inflammatory response in rheumatoid arthritis and its blockers possess anti-arthritic properties. Telmisartan is an angiotensin receptor blocker and PPAR-? agonist and its anti-arthritic effects were evaluated. Aims & Objectives: This experimental study was designed to evaluate the anti-arthritic efficacy of telmisartan in pristane induced rat model of arthritis in adult female rats. Place and duration of study: The study was conducted in the Department of Pharmacology, Army Medical College, Rawalpindi, in collaboration with National Institute of Health and Armed Forces Institute of Pathology from July 2020 to August 2020. Material & Methods: Twenty four (24) adult non-pregnant female Sprague Dawley rats were divided in three groups (n=8) designated as Group A (normal control), Group B (arthritic control) and Group C (telmisartan group) & maintained on standard diet and water adlibitum. Rheumatoid arthritis was induced in each rat of Groups B &C by a single intradermal injection of 0.5ml pristane at the base of its tail on day 0 and the disease developed in two weeks. All 3 groups were given distilled water 2.5 ml/kg from 2-4 weeks and Group C was additionally given dissolved telmisartan orally at 2 mg/kg/day. Anti-arthritic efficacy was determined by assessing arthrogram score and total leukocyte count on day 0, 14 and 28 along with histological examination done at the end of the study. Data analysis was done using SPSS version 25. Results: Healthy rats in group A maintained a unremarkable arthogram & histogram score & TLC count of 6675±350/?l during the entire study period. Telmisartan administration in Group C for two weeks after pristane induction resulted in significant reduction in arthrogram score (AS) 9.5±3.66, total leukocyte count (TLC) 7350±550/?l and histological score (HS) to 6.88±1.24 as compared to (AS) 14.50±2.07, WBC 10150±350/?L & (HS) 10.75±2.05 in Group B, left untreated with pristane alone. The intergroup comparison showed significant p value < 0.05 respectively. Conclusion: Anti-arthritic effect was shown by telmisartan as it was able to ameliorate the changes induced by pristane.

Background: There is an association between breast feeding & maternal lipid profile. Pregnancy related hyperlipidaemia reverse quickly with lactation. Objective: To observe Serum Total cholesterol & triglyceride in lactating & nonlactating mother. Method: The present cross sectional study was conducted in the Department of Physiology, Dhaka Medical College, Dhaka, during the period of July 2010 to June 2011. A total 300 subjects were included within the age limit from 20 to 40 years of women. Among them100 were normal healthy subjects & had child above 3 years were considered as group A (control). The rest 200 women were selected as study subject (group B) having child between the age 6 weeks to 2 years. Group B is again subdivided into group B1 (100 lactating mother) & group B2 (100 nonlactating mother). The subjects were selected from pediatric ward & OPD of pediatrics, DMCH and BSMMU, Dhaka. Data were collected in data collection sheet after taking informed written consent of the subjects. The study parameters total cholesterol & Triglyceride were done in the Department of Physiology, Dhaka Medical College. The data were analyzed by computer with SPSS programs using unpaired Student ?t’ test.Results: In group B1 total cholesterol & triglyceride levels were non significantly higher than that of group A but in group B2 these values were significantly higher than that of group A. Within the study groups all these values were significantly higher in nonlactating mother than lactating mother. It was observed that high level of study parameters were more in B2 than that of group B1. Conclusion: From the results of the present study it may be concluded that lactation has effect on lowering serum total cholesterol & triglyceride which may preferably related to health education for the mother. http://dx.doi.org/10.3329/bjpp.v29i1-2.20060Bangladesh J Physiol Pharmacol 2013; 29(1&2) : 1-7

ABSTRACT Seventeen red deer hinds were housed in individual pens and from 28 February until 11 November were injected each week with vehicle (group A; n = 6) or 5 (group B; n = 6) or 12·5 mg (group C; n = 5) of a long-acting formulation of bromocriptine. Liveweight and voluntary food intake (VFI) were recorded for each hind, and blood was collected for determination of progesterone, prolactin, tri-iodothyronine (T3) and cortisol concentrations by radioimmunoassay. Treatment with the high dose of bromocriptine was associated with a significant (P <0·05) reduction in VFI, with the effect being greatest between March and July. There was no treatment effect on liveweight, but there was a significant (P <0·01) interaction between time and treatment due to the faster rate of weight gain in control animals at the beginning of the experiment. Changes in liveweight could be explained by changes in VFI rather than by changes in the efficiency of utilization of intake. Termination of the breeding season was significantly (P <0·01) delayed by 54 days in group C hinds. Growth of the summer coat and subsequent winter coats was delayed by 1 and 3 months respectively in group C hinds, and in groups B and C the duration that animals were in summer coat was increased by about 1 month. The seasonal increase in prolactin concentrations was seen in all groups, but levels were significantly (P <0·05) lower in group C hinds. Concentrations of T3 and cortisol were not affected by bromocriptine. J. Endocr. (1988) 119, 413–420

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.
