Antiviral Efficacy

ABSTRACT The antiviral efficacy of orally administered adefovir dipivoxil was evaluated in an 18-week study (12 weeks of treatment and 6 weeks of recovery) conducted with woodchucks chronically infected with woodchuck hepatitis virus (WHV). Adefovir dipivoxil is a prodrug of adefovir designed to enhance its oral bioavailability. Following administration of 15 mg of adefovir dipivoxil per kg of body weight in four WHV-infected animals, the mean maximum concentration of adefovir in serum was 0.462 μg/ml, with an elimination half-life of 10.2 h, and the oral bioavailability of adefovir was estimated to be 22.9% (±11.2%). To study antiviral efficacy, the animals were divided into three groups. There were six animals each in a high-dose group (15 mg/kg/day) and a low-dose group (5 mg/kg/day). A vehicle control group consisted of five animals because WHV DNA was detectable only by PCR at the time of the study in one of the original six animals. Efficacy was evaluated by determining the levels of WHV DNA in serum. The geometric mean WHV DNA level for the high-dose group diminished by >40-fold (>1.6 log10) after 2 weeks of treatment and >300-fold (>2.5 log10) at 12 weeks. There was a >10-fold reduction in five of six low-dose animals by 2 weeks, but levels were unchanged in one animal. By 12 weeks of treatment there was a >45-fold (>1.6 log10) reduction of WHV DNA levels, and serum WHV DNA levels were below the limit of quantification in three of six animals. Viral DNA levels returned to pretreatment levels during the 6-week recovery period. There were no clinically significant changes in body weight, hematology, or serum chemistry values, including bicarbonate or lactate, in any of the treated animals. No histologic evidence of liver injury was apparent in the biopsies. Under the conditions of this study, adefovir dipivoxil was an effective antihepadnaviral agent.

And Control

Background: Cannabis sativa is an annual herbaceous plant in the Cannabis genus. The cannabis plant is widely regarded as a potent psychoactive, medicinal plant. Reportedly used for recreation and as intoxicant. The medical uses of the plant include effective control and management of chronic health problems such as HIV/AIDs, cancer, cachexia, nausea and vomiting, asthma and hypertension. C. sativa is known to possess antioxidative properties. This study therefore investigated the effects of C. sativa on antioxidant concentrations in albino Wistar rats. Materials and Methods: Thirty (30) rats used for this study were divided into three groups of 10 rats each. Group 1 received distilled water and served as control. Group 2 received C. sativa extract (100 ml/Kg body weight) by gavage and served as low dose group. Group 3 received C. sativa (250 ml/Kg body weight) by gavage and served as high dose group once daily for 28 days. Results: Catalase (CAT) concentration was significantly lower (P<0.05) in the low dose group as compared with control. In the high dose group, CAT concentration was significantly lower (P<0.05) when compared with the low and control groups respectively. Glutathione peroxidase (GPx) and Superoxide dismutase (SOD) concentrations were significantly higher (P<0.05) in the low dose group as compared with their respective control. GPx and SOD concentrations were significantly higher (P<0.05) in the high dose groups as compared to low dose and control groups respectively. Conclusion: CAT concentration decreased dose-dependently, while GPx and SOD concentrations increased dose-dependently among treated groups. Treatment with C. sativa revealed a paradoxical effect on CAT concentration with respect to GPx and SOD concentrations. Therefore, oral ingestion of ethanolic extract of C. sativa may not have significant effect on the body’s antioxidant stores due to the balance created for CAT deficiency by increased GPx and SOD concentrations.

1,3-Dichloropropane (DCP) was administered by gavage for 14 and 90 days to male and female Sprague-Dawley-derived rats (10/sex/group). In the 14-day study using dose levels of 200, 600, and 1800 mg/kg/day, all high-dose group animals died, and none died in the other two treatment groups. Other signs associated with treatment in high-dose animals included languid behavior, salivation (also seen in middose group animals), dyspnea, and prostration. No differences were found between animals in the low-dose or middose groups compared to the control animals for body weight, food consumption, hematology, and gross postmortem and histopathology data. Total protein and albumin blood levels were increased for low-dose and middose females, and middose females, respectively. The clinical chemistry findings appeared to be treatment-related, since they were accompanied by significantly increased liver weights (absolute and relative; both sexes of middose animals) and kidney weights (absolute and relative; middose males). The dose levels used in the 90-day study, chosen on the results of the 14-day study, were 50, 200, and 800 mg/kg/day. All animals survived to termination. Males in the high-dose group exhibited a significant decrease in body weight, whereas females in this group exhibited urine-stained fur. No treatment-related effects were found in food consumption or hematology data. Alkaline phosphatase, alanine aminotransferase (males only), albumin, and total protein for high-dose group animals were increased. These findings were accompanied by increases in liver weight for low-dose (females only), middose, and high-dose animals and kidney weights for middose and high-dose group animals. Microscopic evaluations revealed centrilobular hepatocellular hypertrophy for the high-dose group animals and an exacerbation of chronic progressive nephropathy for middose (males only) and high-dose animals.

(1) Background: The endothelial glycocalyx is a primary target during the early phase of sepsis. We previously reported a newly developed recombinant non-fucosylated antithrombin has protective effects in vitro. We further evaluated the effects of this recombinant antithrombin on the glycocalyx damage in an animal model of sepsis. (2) Methods: Following endotoxin injection, in Wistar rats, circulating levels of hyaluronan, syndecan-1 and other biomarkers were evaluated in low-dose or high-dose recombinant antithrombin-treated animals and a control group (n = 7 per group). Leukocyte adhesion and blood flow were evaluated with intravital microscopy. The glycocalyx was also examined using side-stream dark-field imaging. (3) Results: The activation of coagulation was inhibited by recombinant antithrombin, leukocyte adhesion was significantly decreased, and flow was better maintained in the high-dose group (both p < 0.05). Circulating levels of syndecan-1 (p < 0.01, high-dose group) and hyaluronan (p < 0.05, low-dose group; p < 0.01, high-dose group) were significantly reduced by recombinant antithrombin treatment. Increases in lactate and decreases in albumin levels were significantly attenuated in the high-dose group (p < 0.05, respectively). The glycocalyx thickness was reduced over time in control animals, but the derangement was attenuated and microvascular perfusion was better maintained in the high-dose group recombinant antithrombin group (p < 0.05). (4) Conclusions: Recombinant antithrombin maintained vascular integrity and the microcirculation by preserving the glycocalyx in this sepsis model, effects that were more prominent with high-dose therapy.

Recombinant Human Thyrotropin

AbstractA potential reduction of goiter volume (GV) of recombinant human thyrotropin (rhTSH) on multinodular goiters (MNG) was previously reported but controversial. Hence we conducted a meta-analysis to estimate the effect of rhTSH-stimulated radioiodine therapy in patients with MNG. PubMed, Cochrane, CNKI, VIP, and Wanfang databases were searched. Mean difference (MD) and odds ratios with 95% confidence intervals (95% CI) were derived by using an inverse variance random-effects model and fixed-effects model, respectively. Six studies (n=237) were involved in the analysis. For 12 months follow up, high dose (>0.1 mg) of rhTSH significantly reduced GV (MD=17.61; 95% CI=12.17 to 23.04; p<0.00001) compared with placebo. No effective pooled results of low dose of rhTSH (<0.1 mg) were applicable for only one study included. For 6 months follow up, the source of heterogeneity was determined by subgroup and sensitivity analysis. High dose group showed vast improvement in GV reduction (MD=16.62; 95% CI=1.34 to 31.90; p=0.03). The reduction of low dose group compared with placebo was inferior to high dose group. No available data were obtained to assess the influence of rhTSH after 36 months follow up for the only included study. Hypothyroidism incidence was higher for rhTSH group. No publication bias was seen. High dose of rhTSH treatment-stimulated radioactive 131I therapy after 6 months and 12 months follow up had a better effect in reducing GV, but with higher incidence of hypothyroidism. Owing to the limited methodological quality, more clinical researches are warranted in the future.

Objective. To explore the effect of different doses of propofol and nerve block combined with general anesthesia on the intraoperative anesthesia and postoperative awakening and cognitive function in elder patients with knee osteoarthritis (OA). Methods. According to the inclusion criteria for research object, we selected 98 elderly patients with knee OA who needed surgery and were admitted to our hospital from January 2019 to January 2021 for the study. Patients were divided into the low dose group (given 2 mg/kg propofol by pumping under constant speed during surgery) and the high dose group (given 4 mg/kg propofol by pumping during surgery) by the number table method to compare their indicators including the intraoperative anesthesia effect, with 49 cases in each group. Results. No between-group difference was shown in the anesthesia time and postoperative VAS scores, but the awakening time of the low dose group was significantly shorter than that of the high dose group (P<0.05); the differences in heart rate (HR) values at various time points between the two groups were not obvious, but the high dose group obtained significantly higher HR values at T4 than the low dose group; the mean arterial pressure (MAP) values of both groups were significantly reduced at Ti and then returned to the level before anesthesia (P>0.05); the bispectral index scores (BIS) of both groups experienced a marked drop at Ti and then recovered gradually, but failed to return to the level at T0 till the end, and a between-group difference in BIS indexes presented at Ti; the plasma corticosterone (CORT) concentration at Ti of both groups were significantly lowered and then returned to the level at T0, with no between-group difference; and compared with the low dose group, the high dose group achieved slightly lower mini-mental state examination (MMSE) scores at 24-72 h after surgery, with no significant difference between them (P>0.05). Conclusion. The therapy of different doses of propofol and nerve block combined with general anesthesia has no significant effect on the cognitive function in elderly knee OA patients after surgery. With the nerve block improving the analgesic effect, a low dose of propofol is good for the postoperative awakening of patients. Different doses of propofol inhibited the stress response to a different degree and produced good anesthesia outcomes in elderly patients, but comparatively speaking, a low-dose propofol ensures more smooth indexes and less effect on the intraoperative hemodynamics.

Abstract Background: The blood saving efficacy of TXA in cardiac surgery has been proved in several studies, but TXA dosing regimens were varied in those studies. Therefore, we performed this study to investigate if there is a dose dependent in-vivo effect of TXA on fibrinolysis parameters by measurement of fibrinolysis markers in adults undergoing cardiac surgery with CPB, which has not been systematically elucidated.Methods: A double-blind, randomized, controlled prospective trial was conducted from February 11, 2017 to May 05, 2017. Thirty patients undergoing cardiac valve surgery were identified and randomly divided into a placebo group, low-dose group and high-dose group by 1: 1: 1. Fibrinolysis parameters were measured by plasma levels of D-Dimers, plasminogen activator inhibitor-1 (PAI-1), thrombin activatable fibrinolysis inhibitor (TAFI), plasmin-antiplasmin complex (PAP), tissue plasminogen activator (tPA) and thrombomodulin (TM). Those proteins were measured at five different sample times: preoperatively before the TXA injection (T1), 5 min after the TXA bolus (T2), 5 min after the initiation of CPB (T3), 5 min before the end of CPB (T4) and 5 min after the protamine administration (T5). A Thrombelastography (TEG) and standard coagulation test were also performed.Results: Compared with the control group, the level of the D-Dimers decreased in the low-dose and high-dose groups when the patients arrived at the ICU and on the first postoperative morning. Over time, the concentrations of PAI-1, TAFI, and TM, but not PAP and tPA, showed significant differences between the three groups (p <0.05). Compared with the placebo group, the plasma concentrations of PAI-1 and TAFI decreased significantly at the T3 and T4 (p <0.05); TAFI concentrations also decreased at the T5 in low-dose group (p <0.05). Compared with the low-dose group, the concentration of TM increased significantly at the T4 in high-dose group. No significant differences were observed in the levels of the coagulation proteins at any points between the groups.Conclusions: The vivo effect of low dose TXA is equivalent to high dose TXA on fibrinolysis parameters in adults undergoing valvular cardiac surgery with cardiopulmonary bypass, and we recommend a low dose TXA regimen for those patients.Clinical trial number and registry URL: ChiCTR-IPR-17010303; http://www.chictr.org.cn, Principal investigator: Zhen-feng ZHOU, Date of registration: January 1, 2017.

Objective: To study the effects of the ethnic medicine Polygala fallax Hemsl with Guangxi characteristics on the sex hormones and ?-EP in research objective perimenopausal rat models. Methods: 40 female SPF rats were randomly divided into 4 groups, including the normal, model, high-dose and low-dose groups. Rats of three groups except for the normal one were treated with perimenopausal modelling through the method of subcutaneous injection of compound 4-VCD for 15 consecutive days. Rats of the normal and model group were normally fed without any treatment. Rats of the high-dose and low-dose groups were administered by high- and low-dose intragastric administration of the extract of Polygala fallax Hemsl. According to the menstrual cycle of the vaginal smear of the rat, each menstrual cycle is a course of treatment and 6 consecutive courses of treatment would be given. The indexes of serum sex hormones (E2, FSH, LH) and ?-EP of rats in each group were observed after treatment. Results: After the treatment of 6 cycles, for the levels of ?-EP and E2, the model group was lowest (P<0.05), the normal group was highest (P<0.05); and the high-dose group was higher than the low-dose group; For the levels of FSH and LH, the normal group was lowest (P<0.05), the model group was highest (P<0.05), and the high-dose group was lower than the low-dose group. Conclusion: Guangxi characteristic national medicine Polygala fallax Hemsl can effectively improve the levels of serum sex hormones and ?-EP in perimenopausal rat models and relieve the related symptoms with a certain dose-effect relationship.

Chronic toxicity studies were conducted by maintaining groups of 50 F344 rats and 50 B6C3F1 mice of each sex on nutritionally complete diets containing 0%, 0.6%, or 1.2% propyl gallate for 103 weeks. Survival of rats and mice of both sexes was not significantly affected by the administration of this compound. Dosed rats and mice showed growth retardation and reduced feed utilization efficiency. Increased incidence of hepatic cytoplasmic vacuolization and suppurative inflammation of the prostate gland were observed in dosed male rats and were considered to be related to propyl gallate administration. Tumors of the preputial gland, islet ceil tumors of the pancreas, and pheochromocytoma of the adrenal gland were observed with significantly (p < 0.05) higher incidence in the low-dose male rats; however, there was little evidence of a dose response or of an effect in the high-dose group. Rare tumors (an astrocytoma and a glioma) were found in the brains of two low-dose female rats but none was found in the high-dose group. Malignant lymphoma occurred with a significant (p < 0.05) positive trend in male mice and the incidence in the high-dose group was significantly (p < 0.05) higher than that of the concurrent controls. However, the high-dose incidence was not significantly different from the historical control rate for the laboratory that conducted the bioassay. Under the conditions of the bioassay, propyl gallate was not considered to be clearly carcinogenic for F344 rats, although the increased incidence of preputial gland tumors, islet-cell tumors of the pancreas, and pheochromocytoma of the adrenal glands in low-dose male rats may have been related to compound administration. Thus, the evidence for carcinogenicity in male rats is regarded as being equivocal, while there was no indication of a carcinogenic response in female rats. Propyl gallate was not considered to be carcinogenic for B6C3F1 mice, although the increased incidence of malignant lymphoma in dosed male mice may have been related to administration of the test compound.

We used in situ gastrocnemius muscle of anaesthetized dogs to test the hypothesis that O2 radical production during muscle contraction contributes to fatigue. Muscle tension was measured with a force transducer and blood flow was monitored with an electromagnetic flow probe. Muscle contractions were produced by stimulating the nerve for 15 min at 20 Hz, 12 trains/min, and a duty cycle of 0.25. Three groups of seven animals were given an infusion of 0.2 mL∙min−1 of either saline, low-dose oxygen radical scavengers (250 IU∙mL−1 superoxide dismutase, 640 IU∙mL−1 polyethylene glycol (PEG)-catalase, 0.25 mg∙mL−1 deferoxamine, and 0.1 mg∙mL−1 oxypurinol), or high-dose oxygen radical scavengers (3300 IU∙mL−1 uperoxide dismutase, 6600 IU∙mL−1 PEG-catalase, 2.5 mg∙mL−1 deferoxamine, and 0.1 mg∙mL−1 oxypurinol). Blood flow and vascular resistance of the gastrocnemius muscle during stimulation did not differ among groups. After 15 min of stimulation, the developed tension (represented as a percentage of initial tension developed) was 66 ± 7% in the saline treated group, 70 ± 6% in the low-dose group, and 70 ± 4% in the high-dose group. The change in tension during recovery was not significant in the control or low-dose groups. However, there was partial recovery in the high-dose group. In conclusion, in this preparation, oxygen radical scavengers did not delay the development of decreased muscle tension.Key words: muscle fatigue, oxygen free radicals, resistance, flow.

Abstract Background Administration of an optimal dose of anesthetic agent to ensure adequate depth of hypnosis with the lowest risk of adverse effects to the fetus is highly important in cesarean section. Sodium thiopental (STP) is still the first choice for induction of anesthesia in some countries for this obstetric surgery. We aimed to compare two doses of STP with regarding the depth of anesthesia and the condition of newborn infants. Methods In this clinical trial, parturient undergoing elective Caesarian section were randomized into two groups receiving either low-dose (5 mg/kg) or high-dose (7 mg/kg) STP. Muscle relaxation was provided with succinylcholine 2 mg/kg and anesthesia was maintained with O2/N2O and sevoflurane. The depth of anesthesia was evaluated using isolated forearm technique (IFT) and bispectral index (BIS) in various phases. Additionally, infants were assessed using Apgar score and neurobehavioral test. Results Forty parturient were evaluated in each group. BIS was significantly lower in high-dose group at skin incision to delivery and subcutaneous and skin closure. Also, significant differences were noticed in IFT over induction to incision and incision to delivery. Apgar score was significantly lower in high-dose group at 1 min after delivery. Newborn infants in low-dose group had significantly better outcomes in all three domains of the neurobehavioral test. Conclusion 7 mg/kg STP is superior to 5 mg/kg in creating deeper hypnosis for mothers. However, it negatively impacts Apgar score and neurobehavioral test of neonates. STP seems to has dropped behind as an acceptable anesthetic in Cesarean section. Trial registration IRCT No: 2016082819470 N45, 13/03/2019.
