Russell's viper (Daboia russelli siamensis) venoms of four different lengths (21-25 cm, 40-60 cm, 81-90 cm and 101-110 cm) were studied by SDS-PAGE electrophoresis and immunoblotting. Studies on biological and biochemical properties of the venom were also carried out. The venom of young snakes (21-60 cm) had a high lethal potency and possessed powerful(More)
A prospective study of the efficacy of applying local pressure by compression pads in retarding spread of venom was carried out on 15 cases of bite by Russell's viper (Daboia russelii siamensis) in Myanmar. A firm rubber pad was applied with cotton bandaging over the site of bite and the limb was immobilized with a splint. Serial monitoring of venom levels(More)
Hb Constant Spring (Hb CS), the gene (alpha(CS)) of which arises from a point mutation in the termination codon of the alpha2-globin gene, is the most prevalent variety of nondeletional alpha-thalassemia (alpha-thal) in Asian populations. It is a major cause of Hb H disease in compound heterozygotes who have Hb CS combined with a duplicated alpha gene(More)
An improved enzyme immunoassay technique (EIA) was used in the diagnosis of 311 suspected Russell's viper bite cases in Myanmar [Burma], 181 of whom (58%) had systemic envenoming. Russell's viper venom was detected in the sera of 175 (56.3%), cobra or green pit viper venoms in 4 (1.3%), and no venom in the remaining 132 (42.4). Among 175 of these patients(More)
The efficacy of the modified compression immobilization technique in retarding spread of radio-labeled Russell's viper venom in 3 rhesus monkeys (Macaca mulata) and "mock venom" NaI131 in 14 human volunteers was studied. 0.1 microgram of Russell's viper venom having 10 microCi radioactivity in 0.2 ml normal saline containing 0.5% bovine serum albumin was(More)
A prospective study of the development, intensity and protective ability of the antibody response to Russell's viper bite and its relation to the severity of envenoming was carried out in 15 patients 3 to 116 weeks after the bites using enzyme immunoassay. Retrospective screening in 123 cases revealed antibody in 112/123 (91%) which could be detected from 1(More)
Venom, venom IgG and IgM antibody and total serum IgG levels following king cobra bites in two reptile handlers were measured by enzyme immunoassay. The patient in case 1 received antivenom while the patient in case 2 did not. Case 1 made a complete recovery following the bite and produced a high titre short-lived antibody. Venom antigen was not detected in(More)
Screening of 3 common alpha-thalassemia (thal) deletions (-alpha3.7, -alpha4.2 and --SEA) in Southeast Asia was done by polymerase chain reaction in 170 unrelated Myanmar thal patients receiving transfusions. Thal deletions were detected in 27 patients (15.9%) as: (1) alpha-thal-2 (-alpha3.7/alphaalpha) in 12 heterozygous or hemoglobin (Hb) E-beta-thal(More)
