The aim of the present study was to determine the prevalence of Dirofilaria immitis in stray, pet, and working dogs (n = 413, 266, and 103, resp.) from Guwahati (Assam) and Aizawl (Mizoram), areas located in two Northeastern States of India. Diagnostic methods applied were microscopy (wet film and Knott's concentration technique), immunological test (Ag(More)
BACKGROUND The North Eastern Region in India is endemic for canine heartworm disease but in clinics accurate diagnosis is some times difficult. The aim of the present study was to determine the prevalence of occult infections for heartworm disease in canine in two geographical regions of North Eastern India. METHODS A total of 782 numbers of three(More)
In the present investigation, we used standard patch clamp techniques to test whether nitric oxide (NO) generation has any role to play with either activation or inhibition of ATP-sensitive (KATP) channels in guinea-pig urinary bladder. We found that NO generation leads to activation of KATP channels through a cyclic guanosine monophosphate(More)
Thirty-one Tocklai vegetative (TV) tea clones contained caffeine and total catechin 44.39 and 227.55 mg/g dry weight of leaves, respectively. The (-)-epigallocatechin gallate (EGCG) was the most abundant (109.60 mg/g) followed by -(-)-epigallocatechin (EGC, 44.54 mg/g), (-)-epicatechin gallate (ECG, 41.74 mg/g), (-)-epicatechin (EC, 27.42 mg/g) and(More)
In the present study, the mechanism of relaxant response of nitric oxide precursor, L-arginine, was investigated in goat isolated coronary artery. L-arginine (1 mM) reversed the U-46619 (1 microM)-induced contraction both in endothelium-intact and endothelium-denuded arterial ring preparations. L-arginine analogues, L-NAME, L-NNA and L-NMMA and the guanylyl(More)
AIM To determine the prevalence and diversity of Eimeria spp. in dairy cattle present in and around Guwahati, Kamrup district, Assam, India. MATERIALS AND METHODS A total of 2339 fecal samples of calves (535), heifer (641) and adult (1163) cattle were screened for 1 year present in and around Guwahati, Assam for detection of Eimeria oocysts by flotation(More)
AIM To know the prevalence of gastrointestinal nematode larvae (L3) in the grazing land of cattle in Guwahati, Kamrup district, Assam. MATERIALS AND METHODS Pastures were collected and examined for the presence of nematode larvae (L3) from six localities of Guwahati at monthly interval from August 2012 to July 2013. The counted larvae were then expressed(More)
(2014) Seroprevalence of canine dirofilariosis, granulocytic anaplasmosis and lyme borreliosis of public health importance in dogs from India's North East, Veterinary World 7(9): 665-667. Abstract Aim: Vector-borne infections namely dirofilariosis, ehrlichiosis, anaplasmosis and lyme borreliosis are being recognized as emerging and/or re-emerging problems(More)
The procedure of countercurrent immunoelectrophoresis in the diagnosis of Taenia hydatigena cysticercosis in goats was carried out for antemortem diagnosis of T. hydatigena cysticercosis in experimentally and naturally infected goats. The antigens of cyst fluid, scolex and membrane of T. hydatigena metacestodes were purified and compared. The sensitivity of(More)
In the present investigation we have examined the hypothesis that calcium-dependent K+ channels (K(Ca)) are involved in the sodium nitroprusside (SNP)-induced vasodilatation of goat coronary artery. SNP (10(-9)-3 x 10(-6) M), added cumulatively, relaxed K+ (30 mM)-contracted coronary artery ring segments in a concentration-dependent manner with an EC50 of(More)
