Comparative Study of Serum Profile in Bitches Treated for Transmissible Venereal Tumor by Autohaemotherapy

A total of 18 bitches in the period in the period of six month diagnosed for transmissible venereal tumor in Teaching Veterinary Clinical Complex, Nagpur by per vaginal examination and vaginal cytology. These bitches were divided randomly into three groups, viz., Group I (Inj. Vincristine @ 0.025mg/kg slow IV in DNS and Injection Botropase 1ml IM for 1st week), Group II (Inj. Vincristine @ 0.025mg/kg slow IV in DNS and Tab. Amoxycillin and Potassium Clavinate for first 7 days orally) and Group III (treated with autohaemotherapy@10 ml whole blood IM) for once in week and continue for 5 week. At the time of treatment, liver and kidney function tests were performed. During the course of treatment significant variation was noted in Group I and II in BUN values while creatinine values changes significantly in all treatment groups. In case of SGPT only significant changes observed in Group I. Rest of the changes in serum prolife found to be non significant. Also from recovery point of view we noted that, it was faster in Group I and II compare than Group III. Side effects observed only in Group I and II. From the study we concluded that autohaemotherapy will be an alternate option for treatment of TVT in bitches who shows the excessive side effects of Vincristine Sulphate.

Treatment and Regression of Transmissible Venearal Tumour in Dogs

Antimicrobial resistance threatens the effective treatment of vast range of bacterial, fungi and viral diseases. Transmissible venereal tumour (TVT) is one of the highly contagious tumour in dogs commonly affecting sexually active stud and bitches. The disease was observed in a male and female Alsatian of about 3 years of age. Both dogs were sexually active and are utilized for breeding purposes. Samples were collected from the TVT growth on both the female and male genitalia. The samples were subjected to cytology and confirmatory diagnosis was made on the gross appearance of cauliformlike lesion and appearance of roundish cells with multiple vacuoles in the cytoplasm of the TVT tumour cells. Treatment was achieved by 3 doses of Vincristin sulphate injection USP1mg/ml Vinlon TM 1 intravenously through a cannula. There was no report of recrudesce of growth post treatment. Conclusion: TVT appear to exhibit genetic preference for sexually active Alsatian breed of dogs within the age bracket of 3 years and above. Despite the confronting challenge of drug resistance in medicine, intravenous administration of vincristine sulphate has remained efficacious in achieving complete regression of TVT the growth in dogs.

Cytological and Histopathological Characteristics of Canine Transmissible Venereal Tumour in Male and Female Dogs Before and After Vincristine Treatment

Canine transmissible venereal tumour (CTVT) is a neoplasia naturally transmitted in susceptible dogs through coitus. CTVT has a worldwide distribution, with a high prevalence in tropical and sub-tropical urban environments. The study aimed at evaluating CTVT lesions in local breeds of dogs and to assess morphological changes based on sex before and after administration of vincristine sulphate. Clinical and gross morphology, fine needle aspirates cytology (FNAC) and routine histopathology methods were used. Two FNAC and histopathological microscopic slide sections from each of the seven sampled dogs were stained with Giemsa stain and Hematoxylin and Eosin. All dogs were treated with vincristine once weekly over a six weeks period after which clinical morphological and histopathological changes were assessed. Grossly, before treatment the tumour masses appeared irregular, cauliflower like with tendency to bleed, sizes ranged from ≥5cm to ≤2cm with or without metastasis to regional lymph nodes. Cytologically, the tumours had homogenous, sheet-like cellular mass. Cytoplasm with punctate vacuoles, anisokaryosis with anisonucleoliosis and coarse to reticulate nuclear chromatin were seen. Lymphocytoid cell pattern was dominant cell type. Histopathology showed sheets of round cells with nuclear and cytoplasmic variations. Histopathology of the treated dog revealed hyper-cellularity, absence of nucleoli, prominent mitotic figures, reduced cell size and presence of inflammatory cells. There was no difference on the cellular changes after vincristine treatment between female and male dogs. Cytology and histopathology showed that vincristine sulphate suppresses the development of tumour through alteration of cellular morphology with no difference between male and female dogs.

In-vitro cytotoxic and anti-Vibrio cholerae activities of alcoholic extracts of Desmodium triflorum (L.) whole plant and Terminalia citrina (Roxb.) fruits

Background The majority of epidemic Vibrio cholerae strains have become resistant to multiple antimicrobial agents for many reasons, including mutations, horizontal gene transfers, etc. Therefore, secondary means of treatment are needed to overcome this impediment in combating cholera. Desmodium triflorum (L.) and Terminalia citrina (Roxb.) are extensively used in traditional medicine. Therefore, the present study aims to evaluate the antibacterial activity of methanolic and ethanolic extracts of Desmodium triflorum (L.) whole plant and Terminalia citrina (Roxb.) fruits against V. cholerae isolates. Methods Initially, different extracts of both plant materials were subjected to qualitative phytochemical screening. Anti-V. cholerae activities were assessed by performing MIC (minimum inhibitory concentration) test using disc diffusion method with different concentrations (1.25, 2.50, 8.00, 10.00, 12.50, 15.00 mg/ml) where standard discs of gentamycin and meropenem (10 μg/disc) were used. Further, Brine shrimp lethality bioassay was done to evaluate the extracts’ cytotoxic activities using different concentrations (800, 400, 200, 100, 50, 25, 12.5, 6.25 μg/ml) against vincristine sulphate. Results The preliminary screening confirms the presence of convenient phytochemical constituents like flavonoids, alkaloids, glycosides, tannins, etc., and are liable for the emergence of the antibacterial activities in different strains. The minimum inhibitory concentrations of both methanolic and ethanolic extracts of Terminalia citrina (fruits) and Desmodium triflorum (L.) (whole plant) were found to be 2.50 mg/ml and 5 mg/ml, respectively. Moreover, 100% mortality was observed only in ethanolic extract of Terminalia citrina fruits at the highest concentration (800 μg/ml). In comparison, the rest of the test extracts showed less than 90% mortality at the highest concentration (800 μg/ml). Conclusions Both plants possess significant phytoconstituents and showed appreciable anti-V. cholerae activities with mild toxicity. Hence, Desmodium triflorum (L.) whole plant and Terminalia citrina (Roxb.) fruits may be recommended as potential phytotherapy against cholera disease.

Treatment of Canine Transmissible Venereal Tumour using Different Surgico-chemotherapeutic Protocols

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.

Fatty acid analysis, cytotoxicity, antimicrobial and antioxidant activities of different extracts of the flowers of Nyctanthes arbor-tristis L.

The fatty acid analysis and biological activity of n-hexane, dichloromethane, ethyl acetate and methanol extracts of Nyctanthes arbor-tristis L. flowers are reported. Five fatty acids namely palmitic (44.15%), stearic (19.34%), arachidic (15.06%), behenic (9.77%) and lignoceric (11.69%) acids were identified. From cytotoxicity test, the LC50 values (the median lethal concentration) for n-hexane, dichloromethane, ethyl acetate and methanol extracts as well as for standard vincristine sulphate were found 7.05, 4.67, 3.14, 5.53 and 0.50 μg/ml, respectively. Antibacterial activity results of different extracts were compared with standard antibiotic ciprofloxacin and tetracycline by measuring the zone of inhibition diameter in millimeter. The dichloromethane and ethyl acetate extracts showed significant antibacterial activity. From antioxidant activity test, IC50 values (50% inhibitory concentration) of n-hexane, dichloromethane, ethyl acetate, methanol extracts and ascorbic acid were found to be 291.92 mg/ml, 45.74 μg/ml, 21.86 μg/ml, 64.30 μg/ml and 3.98 μg/ml, respectively.

Radiographic, Computed Tomographic and Cellular Phenotypic Features of Primary Nasal Transmissible Venereal Tumors in Four Dogs

Primary nasal canine transmissible venereal tumor (CTVT) is a rare disease, developed by allografted transmission of neoplastic cells in the nasal cavity. The disease reported quite uncommonly in free roaming dogs with social behaviour of excessive licking and vigorously sniffing the affected parts of the other dogs in an endemic community. A non-resolving chronic epistaxis and/or serosanguinous discharge from nares is a common historical complaint. Usually, cytology of the nasal discharge/epistaxis or fine-needle aspiration (FNA) of nasal tissue is sufficient for definitive diagnosis. Currently, computed tomography scan (CT-scan) is the best modality to check the invasiveness of the disease and perform modified Adams staging of canine nasal tumors. In present study, all four dogs have stage-4 nasal tumors, due to the complete or partial lysis of the cribriform plate and lymphocytoid plasmacytoid (mixed) phenotype of the neoplastic cells based on the cellularity of cytological samples. All four dogs responded well to five cycles of vincristine sulphate and recovered completely from presented clinical signs. Prognosis is good based on the findings of present study.

A Case Report on Canine Transmissible Venereal Tumor

Background: A male Japanese spitz (3 years) was brought at Himalayan Animal Rescue Trust (HART), Pokhara with a complaint of swollen gums and loss of appetite. A lobulated tumorous mass was seen at the gingival region on physical examination.Objectives: Diagnosis and treatment of condition detected in the dog was the major objective.Methods: Impression smear of tumor cell was prepared and was observed under oil immersion microscope (100x).Results: Microscopic examination shows the presence of vacuolations within the cytoplasm and the condition was diagnosed to be CTVT.Treatment: Chemotherapy was performed using the most effective cytostatic agents I.e. Vincristine sulphate (once a week, I/v). The chemotherapy was repeated for 3 doses till the tumor gets completely regressed.Conclusion: The condition was resolved after third session of chemotherapy. Myelosuppression and gastrointestinal effects like vomiting are the major complications of using vincristine.
