ABSTRACT
Background: In India, about 1 million people are bitten by snakes more in the rural area and they get admitted to hospitals. About 50,000, people die of snake bites every year in India. The patients admitted with poisonous snake bites were treated with polyvalent anti snake venom serum. Aim: To determine the significant difference and outcome between High Dose and Low dose Polyvalent Anti Snake Venom Serum (PVASVS), with regards to age gender and severity of coagulation abnormalities. The cost of ASV has an economic impact and if low dose ASV saves the scarce resource. Materials and Methods: 45 patients bitten by snake admitted and treated which included both males and females were taken up for this study based on Poisson model of sampling. All the patients had cellulitis, renal failure and varying degree of coagulation abnormalities. They were classified into LDG and HDG depending on the number of PVASVS they received which was ≤25 vials or >25 vials respectively. This was decided based on the treatment of ASV analyzed using chi-square contingency statistically for its significance. Results: The age and clotting time as such do not have association to distinguish HDG or LDG. It was revealed that Gender has an effect that female HDG are 26.3% (5 out of 19) as compared to male 73.7% (14 out of 19). In each group, 2 patients died out of 18, LDG (11%) 27 in HDG (7.4%) 62.9% of patients in LDG and 38.8% in HDG required hospital stay more than 10 days. Conclusions: The female gender falls in low dose conserving ASV. The LD ASV demands higher duration of stay (more than 10 days) in the hospital. The age, coagulation abnormality did not establish the significant results in the LDG and HDG.
ABSTRACT
Objective: To explore the correlation between the hemostatic activity and commercial grades of Panax notoginseng. Methods: After treatment with different commercial grades of P. notoginseng, the mice blooding time (BT) and clotting time (CT) were measured. At the same time the prothrombin time (PT), activation part thrombin time (APTT), fibrinogen (FIB), and platelet count (PLT) were also detected by fully automated blood cell analyzer. The contents of dencichine were determined by HPLC. Results: Mice BT, CT, PT, and APTT were decreased and PLT was increased significantly in all the commercial grades of P. notoginseng. Among all the commercial grades, the countless Tou Sanqi Powder has the best hemostatic activity. There is no correlation between the commercial grades and homostatic activity. Different contents of the extracted dencichine were observed among different commercial grades of P. notoginseng. The highest content of dencichine was 0.98% in countless Tou Sanqi and the lowest was 0.52% in 80 Tou Sanqi. There is no statistical correlation between the dencichine and hemostatic activity or dencichine and commercial grades of P. notoginseng. Conclusion: There is no statistical correlation between the commercial grades of P. notoginseng and haemostatic activity or dencichine contents. The dencichine in countless Tou Sanqi which is the cheapest of all displays the better hemostaic activity than those in 13 or 20 Tou Sanqi whose cost is almost as ten times as countless Tou Sanqi's.
