Crimean-Congo hemorrhagic fever is a tick-borne viral disease reported from more than 30 countries in Africa, Asia, South-East Europe, and the Middle East. The majority of human cases are workers in livestock industry, agriculture, slaughterhouses, and veterinary practice. Nosocomial transmission is also well described. Clinical manifestations are nonspecific and symptoms typically include high fever, headache, malaise, arthralgia, myalgia, nausea, abdominal pain, and nonbloody diarrhea. Patients may show signs of progressive hemorrhagic diathesis. Laboratory abnormalities may include anemia, leukopenia, thrombocytopenia, increased AST/ALT levels, and prolonged prothrombin, bleeding, and activated partial thromboplastin times. Diagnostic methods include antibody detection by enzyme-linked immunosorbent assay, virus isolation, antigen detection, and polymerase chain reaction. The mainstay of treatment of Crimean-Congo hemorrhagic fever is supportive, with careful maintenance of fluid and electrolyte balance, circulatory volume, and blood pressure. The Crimean-Congo hemorrhagic fever virus is susceptible to ribavirin in vitro. There is no controlled study evaluating oral versus intravenous ribavirin in treating Crimean-Congo hemorrhagic fever patients, but few studies have evaluated oral ribavirin. This article reviews the epidemiology, pathogenesis, clinical manifestations, diagnosis, treatment, prevention, and prognosis of Crimean-Congo hemorrhagic fever with a special focus on oral ribavirin as a choice of medical treatment.

Multiorgan dysfunction ensuing from severe heatstroke includes hypotension, hepatic and renal failure, hypercoagulable state, activated inflammation, and cerebral ischemia and injury. We attempted to assess whether human umbilical cord blood-derived CD34+ cell therapy improves survival during experimental heatstroke by attenuating multiorgan dysfunction. Anesthetized rats, immediately after the onset of heatstroke, were divided into 2 major groups and given CD34- or CD34+ cells (1 x 10(5)-5 x 10(5)/mL/kg body weight) i.v. They were exposed to ambient temperature of 43 degrees C to induce heatstroke. Another group of rats were exposed to room temperature (26 degrees C) and used as normothermic controls. Hypotension, hepatic and renal failure (evidenced by increased serum urea nitrogen, creatinine, aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase levels in plasma), hypercoagulable state (evidenced by increased prothrombin time, activated partial thromboplastin time, and D-dimer, and decreased platelet count and protein C in plasma), activated inflammation (evidence by increased TNF-alpha levels in serum), and cerebral dysfunction (evidenced by intracranial hypertension, cerebral hypoperfusion and hypoxia, and cerebral ischemia and injury) were monitored. When the CD34- cell-treated or untreated rats underwent heat stress, their survival time values were found to be 19 to 23 min. Resuscitation with CD34+ cells significantly improved survival time (duration, 63-291 min). As compared with normothermic controls, all CD34- cell-treated heatstroke animals displayed hypotension, hepatic and renal failure, hypercoagulable state, activated inflammation, and cerebral ischemia and injury. However, CD34+ cell therapy significantly caused attenuation of all the above-mentioned heatstroke reactions. In addition, the levels of IL-10 in plasma and glial cell line-derived neurotrophic factors in brain were all significantly increased after CD34+ cell therapy during heatstroke. Our data indicate that CD34+ cell therapy may resuscitate persons who had a heatstroke by reducing multiorgan dysfunction or failure.

Hyperbaric oxygen has been found to be beneficial in treating heatstroke animals. We attempted to further assess the possible mechanism of therapeutic protection offered by hyperbaric oxygen in experimental heatstroke. Anesthetized rats, immediately after the onset of heatstroke, were randomized into the following groups and given: a) hyperbaric oxygen (100% O(2) at 253 kPa for 1 h); or b) normal air. They were exposed to 43 degrees C temperature to induce heatstroke. When the untreated rats underwent heat stress, their survival time values were found to be 20-24 min. Resuscitation with hyperbaric oxygen increased the survival time to new values of 152-176 min. All untreated heatstroke rats displayed cerebrovascular dysfunction (evidenced by hypotension, intracranial hypertension, and cerebral hypoperfusion, hypoxia, and ischemia), hypercoagulable state (evidenced by increased levels of activated partial thromboplastin time, prothrombin time, and D-dimer, but decreased values of platelet count and protein C in plasma), and tissue ischemia/injury (evidenced by increased levels of creatinine, serum urea nitrogen, aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase in plasma, and dihydrobenzoic acid, lipid peroxidation, and oxidized-form glutathione/reduced-form of glutathione ratio in hypothalamus). The cerebrovascular dysfunctions, hypercoagulable state, tissue ischemia/injury, and brain oxidative stress that occurred during heatstroke were all suppressed by hyperbaric oxygen therapy. The current results indicate that hyperbaric oxygen therapy may resuscitate rats that had a heatstroke by decreasing multiple organ dysfunction and brain oxidative stress.

To investigate clinical course and outcome of dengue with acute respiratory failure (ARF), and to identify related risk factors for acquiring ARF in dengue, we retrospectively studied 11 dengue patients with ARF. From June to December 2002, a total of 606 adult patients were diagnosed as having dengue. Eleven (1.8%) of 606 dengue patients had complications of ARF. The main causes of ARF were sepsis (n = 6, 54.5%) and upper gastrointestinal (UGI) bleeding (n = 3, 27.3%). The mortality rate was 72.7% (n = 8). Additionally, univariate analysis showed that age, dyspnea, cough, prothrombin time, activated partial thromboplastin time, aspartate aminotransferase, alanine aminotransferase, blood urea nitrogen, creatinine, albumin, renal insufficiency, acute renal failure, acute hepatic failure, UGI bleeding, and combination bacterial infection were significantly predictive variables associated with dengue patients with ARF.

There has been no previously reported case series study regarding chest radiographic (CXR) presentations in dengue hemorrhagic fever (DHF) patients. We retrospectively studied 363 DHF patients from June to December 2002 in southern Taiwan, and a total of 468 CXRs were obtained and reviewed. More than 50% of these showed abnormalities after the 3rd day, with infiltration only and small pleural effusion as the major findings. Progressive changes during the first week and improvements during the second week were observed in these abnormal CXRs. The CXR presentation was also significantly correlated with laboratory findings (white blood cell count, platelet levels, activated partial thromboplastin time, and alanine aminotransferase and albumin levels), as well as the clinical course (renal insufficiency, liver function impairment, upper gastrointestinal bleeding, combination bacterial infection, and duration of admission) and outcome (mortality). The CXR may therefore be a modality for evaluating the clinical course of DHF and should be made during first week after the onset of illness.

Ischemia/reperfusion (IR) injury in transplanted livers contributes to organ dysfunction and failure and is characterized in part by loss of NO bioavailability. Inhalation of NO is nontoxic and at high concentrations (80 ppm) inhibits IR injury in extrapulmonary tissues. In this prospective, blinded, placebo-controlled study, we evaluated the hypothesis that administration of inhaled NO (iNO; 80 ppm) to patients undergoing orthotopic liver transplantation inhibits hepatic IR injury, resulting in improved liver function. Patients were randomized to receive either placebo or iNO (n = 10 per group) during the operative period only. When results were adjusted for cold ischemia time and sex, iNO significantly decreased hospital length of stay, and evaluation of serum transaminases (alanine transaminase, aspartate aminotransferase) and coagulation times (prothrombin time, partial thromboplastin time) indicated that iNO improved the rate at which liver function was restored after transplantation. iNO did not significantly affect changes in inflammatory markers in liver tissue 1 hour after reperfusion but significantly lowered hepatocyte apoptosis. Evaluation of circulating NO metabolites indicated that the most likely candidate transducer of extrapulmonary effects of iNO was nitrite. In summary, this study supports the clinical use of iNO as an extrapulmonary therapeutic to improve organ function following transplantation.

The clinical information of acute Q fever in Taiwan was limited. A clinical study of 109 adults with serologically documented acute Q fever in the past decade (1994-2005) at 3 referral hospitals in southern Taiwan was reported. Their clinical manifestations, laboratory findings, and clinical outcomes were analyzed. Males predominated (98, 90%). There is a significant correlation between monthly average temperature and case numbers of acute Q fever (r = 0.74, P = 0.006). Fever (99%), chills (69%), and headache (45%) were the common symptoms, and relative bradycardia (44/60, 73 %) was often noted. Acute hepatitis, defined as either serum aspartate aminotransferase >or=60 IU/L or alanine aminotransferase >or=78 IU/L, was found in 88 (85%) cases, and more than one-third (31/87, 36%) had hyperbilirubinemia (serum total bilirubin >or=1.4 mg/dL) at initial presentation. The intervals between initiation of appropriate therapy to defervescence were longer in patients with hyperbilirubinemia than those without hyperbilirubinemia, irrespective of tetracycline or fluoroquinolone therapy. Of note, 8 (7.3%) cases experienced a prolonged period of fever (>28 days). In southern Taiwan, the predominant presentation of acute Q fever is acute febrile illness with hepatitis with or without jaundice. Acute Q fever should be added to the list of differential diagnoses of patients with fever, headache, relative bradycardia, elevated serum aminotransferase levels, or prolongation of activated partial thromboplastin time, irrespective of jaundice.

Laghupatha (Cissampelos pareira) a important medicinal plant in Indian traditional system of medicine and is widely used in many countries by different tribal. Despite the wide use of Cissampelos pareira in folk medicine, no study has been published in the scientific literature about its toxicological profile. In present study 50% aqueous ethanolic extract of Cissampelos pareira (Menispermaceae) was evaluated for the acute and subacute toxicity. In the acute toxicity test, oral administration of 2g/kg of Cissampelos pareira produced neither mortality nor changes in behavior or any other physiological activities in mice. In subacute toxicity studies, no mortality was observed when the two doses of 1 or 2g/kg day of 50% aqueous ethanolic extract of Cissampelos pareira were administered p.o. for a period of 28 days in rats. There were no significant changes occurred in the blood chemistry analysis including glucose, sodium, potassium, calcium, phosphorus, chloride, total cholesterol, high density lipoprotein, triglycerides, total protein, blood urea nitrogen, creatinine, conjugated billirrubin, aspartate transaminase, alanine transaminase, total billirrubin, albumin, prothrombin time and thromboplastin partial time in both sexes of animals. Hematological analysis showed no marked differences in any of the parameters examined (WBC count, platelet and hemoglobin estimation) in either the control or treated group of both sexes. The urinalysis was negative for glucose, ketonic bodies, casts, red blood cells, and albumin in the control and treatment groups. There were no significant differences in the body and organ weights between controls and treated animals of both sexes. Pathologically, neither gross abnormalities nor histopathological changes were observed. Cissampelos pareira was found safe in acute and subacute toxicities while chronic toxicity studies are further required for the support of the safe and sound use of this traditional plant.

The blood hemostatic activity of the Tibetan medicinal herb Lamiophlomis rotata was evaluated in BALB/c mice and Wistar rats. L. rotata aqueous extract (LRAE) was given to mice at concentrations of 0.5, 1.0, 2.0 g/kg body weight and 0.75, 1.5, 3.0 g/kg to rats. The hemostatic activity of LRAE was estimated by changes in bleeding time (BT), prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT) and fibrinogen (FIB). At the same time hepatic function and blood fat indexes including AST, ALT, Alb, Chol and LDL-C were measured also. The results showed that an appropriate level of LRAE could shorten the BT and TT values and increase the Alb level paralleling that of FIB. However, the shortening of the PT was only possible by a high and long administration of LRAE, and no change in APTT was observed. On the other hand, LRAE showed some effects in improving the liver function and reducing blood lipids by decreasing the levels of AST, ALT, Chol and LDL-C. All these changes had a significant dose-effect and time-effect relationship. These results confirm the hemostatic and thromboplastic effects of L. rotata and these effects might be implemented by improving the synthetic function of the liver.

The natural compounds which affect defensive mechanisms of organism are important in prophylaxis and therapy of diseases in human and animals. Lysozyme is an enzyme which originates from chicken egg proteins. It modulates non-specific and humoral immunological mechanisms. A higher bioactivity has a lysozyme dimmer. The aim of study was assessment of influence of the lysozyme dimmer on chosen blood parameters, morphology and functions of internal organs and healing processes of experimental wounds in rabbits. Lysozyme dimmer (KLP-602) was used obtained process polymerisations enzyme lyzosyme from chicken egg white. The experimental group were on New Zealand White rabbits. Systemic reactions were investigated in animals after two injections of lysozyme dimer in dose 0,02 mg/kg b.w. during 21 days. Blood was collected before and after administration of lysozyme dimer in 4, 6, 24 h and in 3, 7, 21 day after first and in 4, 24 h and 3, 7 day after second injection. The following parameters were evaluated of red blood cells number (RBC), hemoglobin concentration (HGB), haematocrit value (HCT), red blood cell indices (MCV, MCH, MCHC), white blood cells number (WBC) and leukogram. Total serum proteins, components C3 and C4 of complement, immunoglobulins G and M, concentration were determined in the serum. Activated partial thromboplastin time (APTT), prothrombin time (PT) and fibrinogen concentration were evaluated in the plasma. Simultaneously, the activity of alkaline phosphatate, GPT and GOT were assessed. Administration rabbits with lysozyme dimmer caused slight decrease in RBC number, Hb concentration, HCT and the neutrophils percentage and increase in the lymphocytes percentage. The concentrations of TSP, immunoglobulins, the components of complement ware increased too. APTT an PT were normal but the fibrinogen concentration was increased. The activity of GOT and GPT were unchanged. Changes are in range of value normal and step out more quickly after two injection than after firste injection. The morphology of organs (liver, lungs, heart and kidneys) was normal.
