Background: Tiryaq-e-arba is a polyherbal Unani antidote/antivenom formulation used in the management of poisoning due to snake bite, scorpion bite as well as in cold poisons since time immemorial. Objectives: Tiryaq-e-arba was not evaluated scientifically before this study carried out, therefore it was studied for antivenom activity by testing on plasma fibrinogen level in Russell's Viper envenomation in rabbits. Material &Methods: The anti-venom activity of the test drug was studied by observing its effect on plasma fibrinogen level in Russell's Viper envenomation in rabbits by the method of Netelson. Results: The plasma fibrinogen level was found to be 171±665.04 mg/100 ml of blood, 36.18±1.12 mg/100 ml of blood, 33.14±0.52 mg/100 ml of blood and 17.9±1.65 mg/100 ml of blood at 0, 1, 3 and 6 hours respectively in control animals while in the test animal it was found to be 157.13±3.44 mg/100 ml of blood, 41.13±2.69 mg/100 ml of blood, 62.09±1.65 mg/100 ml of blood and 54.39±0.73 mg/100 ml of blood respectively. The test showed that though the plasma fibrinogen level in the test lower at 0 hour but it was greater in the control animals at 1, 3 and 6 hours. The increase in plasma fibrinogen level in the test animals at 3 and 6 hours was statistically significant (P<0.001). Conclusions: The finding of the present study was that Tiryaq-e-arba possesses antivenom activity which scientifically support the Unani claim that it is Dafe-Sumoom-al-Hevan (Antivenom or Antidote) and the use of this preparation in corresponding diseases.

To establish the method of integrated weed management in rice nurserybed, phytotoxic factors of herbicide and antidote efficacy were evaluated at the Yeongnam Crop Experiment Station in 1982 and 1984. Seven hundred eighty four research items were carried out as weed control research since 1961. While 65% of these were belonged to rice research, only 6% was attributed to nurserybed among rice research. More herbicidal phytotoxicity exhibited when seedbed was pressed just after seeding than sand covered or uncovered seedbed and also this phytotoxic symptom enhanced by using intact seed compared to pregerminated seed. Rinsing practice of seedbed reduced the phytotoxic effect of butachlor and this effect was more pronounced with the number of rinsing operation increase and at the pressed plot. However, herbicidal efficacy was not significantly decreased by rinsing operation. Growth of rice seedling hardly affected where the herbicide was absorbed through root only compared to absorption from both of root and shoot for pyrazolate, butachlor and thiobencarb. Herbicide antidote `CGA 123'407' completely protected from the phytotoxic effect of pretilachlor without arising any adversal effect in weed control. However, without antidote, pretilachlor showed the most severe phytotoxic symptom among used herbicides.

Nerve agents (sarin, tabun, soman and VX) are class of military important substances able to cause many severe intoxications during few minutes. Currently, the threat of misuse of these agents is daily discussed. Unfortunately, there is no single antidote able to treat intoxication caused by all of these agents. Owing to this fact, new generation of antidotes, especially acetylcholinesterase (AChE; EC 3.1.1.7) reactivators, is still developed. In this study, we have tested four newly developed AChE reactivators: 1-(4-hydroxyiminomethylpyridinium)- 5-(4-carbamoylpyridinium)-3-oxa-pentane dibromide (1), 1-(3-hydroxyiminomethylpyridinium)-5-(4-carbamoylpyridinium)-3-oxa-pentane dibromide (2), 1,5-bis(2-hydroxyiminomethylpyridinium)-3-oxa-pentane dichloride (3) and 1,5-bis(4-hydroxyiminomethylpyridinium)-3-oxa-pentane dibromide (4) for their potency to reactivate in vitro tabun and cyclosarin-inhibited AChE. Their reactivation efficacy was compared with currently the most promising oxime HI-6 (1-(2-hydroxyiminomethylpyridinium)-3-(4-carbamoylpyridinium)-2-oxa-propane dichloride). According to obtained results, two AChE reactivators 1 and 4 were able to reactivate tabun-inhibited AChE. On the contrary, there was no better AChE reactivator than HI-6 able to reactivate cyclosarin-inhibited AChE.

The US Army used MARK-1 composed of atropine autoinjector and 2-PAM autoinjector as a medical countermeasure against nerve agent poisoning. Recently, it has been being replaced by the ATNAA(Antidote Treatment Nerve Agent AutoInjector) for improvement the convenience in use and rapid detoxification effect. ATNAA(FDA approval, NDA 21-175, 2002. 1. 17) is a multi-chambered autoinjector that sequentially delivers atropine and 2-PAM through a single needle to allow Warfighters to survive against lethal exposure to nerve agents. In this paper, our group investigated the case of FDA approval of ATNAA in a point of the various data required by FDA guideline, thereby making it easy to meet the KFDA guideline for the approval of the prototype our group has been developed. The purpose of this study is to provide a reference for efficient research activities to minimize time and cost. Additionally, the purpose of this study is to provide a reference for the planning for the development of similar drug.

Nathaniel Hawthorne mainly deals with the ethical problems of sin and punishment in his works. Through these topics, readers have the opportunity to look more deeply into human nature. In Rappaccini's Daughter, he explains how the power of men influences a woman's life and drives her to death. Her father, Rappaccini, cultivates plants in his garden that are toxic and conducts a scientific experiment that gives his daughter Beatrice a fatal level of toxicity. He insists that this experiment was performed to protect Beatrice, but ultimately, it causes her death. Giovanni, who falls in love with Beatrice, provided an antidote in the attempt to detoxify her, but it resulted in her death. Finally, Baglioni used Giovanni to steer Beatrice to drink the antidote to defend his social status. The three men's selfishness and jealousy led to the demise of Beatrice, who eventually died from the selfish power of men and not due to her toxicity.

Purpose: In many Korean hospitals, serum acetaminophen concentrations in cases of overdose cannot be measured initially because of inadequate laboratory facilities. Under these circumstances, physicians base the administration of the antidote, N-acetylcysteine, on ingestion amounts as determined by initial history taking. We therefore examined the correlated between ingested amounts and serum acetaminophen concentrations. Methods: Medical records were reviewed retrospectively for patients who presented to the ED with acetaminophen overdose between January 2002 and March 2006. Fifty-nine patients were recruited and sixteen patients were excluded. The forty-three remaining patients were placed into either the high-risk or low-risk group based on their ingested amount (140 mg/kg), and were separately categorized into the toxic or non-toxic group based on their serum acetaminophen concentrations, according to the Rurnack-Matthew nomogram. Results: Ten patients (83.3%) among twelve in the high-risk group were found to have non-toxic serum concentrations, and just one patient (3.2%) among thirty-one in the low-risk group fell into the toxic group based on their serum concentrations. The sensitivity and specificity of risk stratification of the ingested amount as a predictor of intoxication requiring antidote therapy were 66.7% and 75.0%, respectively. Conclusion: This study suggests that the therapeutic decision for acetaminophen overdose should not be based solely on ingested amount only, but requires assessment of acetaminophen concentration.

In this study, multi-chambered single autoinjector(2in1) and KMARK-1 containing atropine and 2-PAM(pyridine-2-aldoxime methylchloride) were administered to the beagle's muscle, and blood samples were taken for a certain period of time to compare and evaluate the pharmacokinetic profiles of the two drugs. Male beagles were used and classified into two test groups(G1, G2), and crossover pharmacokinetic studies were performed in two test groups. Blood samples were collected from the jugular vein for analysis after administration. The 90 % confidence interval(CI) for log transformed data indicated that the Cmax for both atropine(log 0.9683 ~ log 1.113) and 2-PAM(log 0.9453 ~ log 1.214) was within the limits of bioequivalence criteria, but the AUC for atropine(log 1.1786 ~ log 1.3238) failed to meet this criteria. This is expected as the amount of atropine dose is 25 % higher for the test as compared to the reference formulation. In summary, in view of the ATNAA(antidote for nerve agent of US) authorization, the Cmax equivalence was more important than AUC equivalence, so in this study, we also focused on verifying the equality of Cmax between the two autoinjectors.
