Study Plan

A study plan was designed to estimate the coagulation parameters like Prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen level and fibrinogen degradation products (FDPs). In this study, coagulation parameters were compared in combined oral contraceptives (COCs) and control group. 40 subjects of COCs with 20 normal females without hormonal contraceptive were included in this study. Blood samples were collected for special coagulation parameters. FDPs were significantly elevated in subjects using COCs as compared to normal control. PT and APTT were shortened in COCs. Fibrinogen levels were increased significantly in COCs when compared with control groups.

Abstract Antitissue factor antibody attenuated the coagulopathic and lethal responses to LD100Escherichia coli, whereas active site inhibited factor Xa inhibited only the coagulopathic response. In this study, we wished to determine: (1) whether active site inhibited factor VIIa blocks the coagulopathic and/or attenuates the lethal effects of LD100E coli and (2) whether these effects are accompanied by attenuation of the inflammatory cytokine response to LD100E coli. Eight baboons infused for 2 hours with LD100E coli also were given five bolus infusions of DEGR VIIa of 280 μg/kg at T = −10 minutes, +2, 4, 6, and 8 hours and observed for changes in vital signs, and the concentrations of hemostatic components (fibrinogen, platelets, fibrin degradation products) and inflammatory mediators (tumor necrosis factor [TNF], interleukin-6 [IL-6], IL-8) at T = 0, 1, 2, 4, 6, and 8 hours. Eight control baboons were also infused with LD100E coli alone and followed as described above. Four of the eight baboons treated with DEGR VIIa were permanent 7-day survivors versus none in the control group. The mean survival times for the treated and control groups were 116 ± 22 and 26 ± 8 hours, respectively. These values differed significantly from each other, (P = .0008). The decrease in platelet and fibrinogen concentrations and the increase in fibrin degradation products observed in the control group were significantly attenuated in the treated group, as was thrombosis of renal glomerular capillaries. Treatment with DEGR VIIa showed no effect on the peak TNF response to LD100E coli at T = 2 hours (170 ± 32 v120 ± 35 ng/mL). DEGR VIIa, however, did attenuate the IL-6 and IL-8 responses at T = 8 hours (ie, the IL-6 concentrations were 81 ± 10 for treated and 1,256 ± 236 for the control groups and the IL-8 concentrations were 28 ± 3.9 for the treated and 60 ± 8.2 for the control group). These values for IL-6 and IL-8 differed significantly from each other between the treated and control groups (P = .0001 and .0074, respectively). It should be noted that the initial responses of IL-6 and IL-8 up to T = 4 hours were not attenuated. We concluded that DEGR VIIa treatment attenuates inflammatory, as well as hemostatic system responses to LD100E coli. We hypothesize that this occurs through interference with the assembly and/or interactions of tissue factor/VIIa complexes.

Abstract Parathyroid adenoma is responsible for 80–85% of cases of primary hyperparathyroidism. Increased fibrinogen levels in patients with adenoma may increase the risk of atherosclerosis and cardiovascular events. The aim of this study was to investigate the relationship between coagulation parameters and parathyroid adenoma. A prospective study included 28 female patients with parathyroid adenoma aged 40–88 years and 27 age-matched healthy controls. The coagulation parameters were assessed for each participant. The mean ages of the patient and control groups were 57.7 ± 10.9 and 53.3 ± 9.31 years, respectively. The mean level of protein S activity was 65.79 ± 13.78 in the patient group and 77.00 ± 15.72 in the control group, and the difference was statistically significant (p = 0.013). The mean fibrinogen levels of the patient and control groups were 338.78 ± 63.87 mg/dL and 304.30 ± 45.67 mg/dL, respectively, and a significant difference was found (p = 0.041). However, no significant difference was evident between the two groups with regard to the D-dimer (p = 0.238), aPTT (p = 0.645), INR (p = 0.406), protein C (p = 0.076), and AT-III (p = 0.180) levels. A positive correlation was observed between adenoma volume and fibrinogen in the patient group (r = 0.711, p = 0.001). The protein S levels were lower and the fibrinogen levels higher in the patients with parathyroid adenoma.

Conjugated linoleic acid (CLA) is a collective term for the positional and geometric isomers of a conjugated diene of linoleic acid (C18:2, n-6). The aims of the present study were to evaluate whether levels of hepatic α-tocopherol, α-tocopherol transfer protein (α-TTP), and antioxidant enzymes in mice were affected by a CLA-supplemented diet. C57BL/6 J mice were divided into the CLA and control groups, which were fed, respectively, a 5 % fat diet with or without 1 g/100 g of CLA (1:1 mixture of cis-9, trans-11 and trans-10, cis-12) for four weeks. α-Tocopherol levels in plasma and liver were significantly higher in the CLA group than in the control group. Liver α-TTP levels were also significantly increased in the CLA group, the α-TTP/β-actin ratio being 2.5-fold higher than that in control mice (p<0.01). Thiobarbituric acid-reactive substances were significantly decreased in the CLA group (p<0.01). There were no significant differences between the two groups in levels of three antioxidant enzymes (superoxide dismutase, glutathione peroxidase, and catalase). The accumulation of liver α-tocopherol seen with the CLA diet can be attributed to the antioxidant potential of CLA and the ability of α-TTP induction. The lack of changes in antioxidant enzyme protein levels and the reduced lipid peroxidation in the liver of CLA mice are due to α-tocopherol accumulation.

SummaryUsing the chromogenic substrate, Tos-Gly-Pro-Arg-pNA-HCL (Chromozym TH, Boehringer Mannheim) plasma thrombin was estimated in six cases of envenomation by Australian elapid snakes. All patients manifested findings chracteristic of defibrination due to envenomation by these snakes. Fibrin-fibrinogen degradation products were grossly elevated, as was plasma thrombin in all cases.Following treatment with antivenene, all abnormal coagulation parameters returned rapidly towards normal by 24 hours and plasma thrombin disappeared.

Introduction: The role of virgin coconut oil in the treatment of allergic rhinitis is controversial. Thus, the aim of the present study is to determine the effects of virgin coconut oil ingestion, in addition to standard medications, on allergic rhinitis. We also studied the side effects of consumption of virgin coconut oil. Methods: Fifty two subjects were equally divided into test and control groups. All subjects received a daily dose of 10mg of loratadine for 28 days. The test group was given 10ml of virgin coconut oil three times a day in addition to loratadine. The symptoms of allergic rhinitis were scored at the beginning and end of the study. Results:, the symptom score were divided into nasal and non-nasal symptom scores. Sneezing score showed a significant difference, however the score was more in control group than test group, indicating that improvement in symptom was more in control group. The rest of the nasal symptom and non-nasal symptom score showed no significant difference between test and control groups. Approximately 58% of the test subjects developed side effects from consumption of virgin coconut oil, mainly gastrointestinal side effects. Conclusion: In the present study, ingestion of virgin coconut oil does not improve the overall and individual symptoms of allergic rhinitis, furthermore it has side effects.
