poses a serious medical threat to humans in Southern and Southeastern Asia. Hemorrhage is one of the conspicuous toxicities related to the pathology of envenoming. Previous in vitro and in vivo studies showed that a silica-derived reagent, sodium silicate complex (SSC), was able to neutralize hemorrhagic and proteolytic activities induced by pit viper venoms, including , and .

Venom Ophthalmia and Ocular Complications Caused by Snake Venom.

Little is known about the detailed clinical description, pathophysiology, and efficacy of treatments for ocular envenoming (venom ophthalmia) caused by venom of the spitting elapid and other snakes, as well as ocular complications caused by snake venom injection. In this paper, we review clinical information of case reports regarding venom ophthalmia and snake venom injection with associated ocular injuries in Asia, Africa, and the United States. We also review the literature of snake venom such as their compositions, properties, and toxic effects.

Bites to the Head: Clinical Spectrum from Case Series.

() is a medically important species of pit viper with a wide geographic distribution in Southeast Asia. Bites by mostly involve the extremities. Little is known about the toxic effects of envenoming to the head because of the infrequency of such occurrence.

Comparing characteristics of adverse drug events between older and younger adults presenting to a Taiwan emergency department.

To compare the proportion, seriousness, preventability of adverse drug events (ADEs) between the older adults (≥ 65 years old) and younger adults (<65 years old) presenting to the emergency department (ED), we conducted a prospective observational cohort study of patients 18 years and older presenting to the ED. For all ED visits between March 1, 2009, and Feb 28, 2010, investigators identified ADEs and assessed cases using the Naranjo adverse drug reaction probability scale. Outcomes (proportion, seriousness, and preventability of ADE, length of ED stay, and hospitalization) and associated variables were measured and compared between younger and older adults.

Toxin ophthalmia caused by nuchal gland secretion of the Taiwan tiger keelback (Rhabdophis tigrinus formosanus).

Rhabdophis tigrinus is a common colubrid snake that can be found in an extensive geographical region in East Asia. It consists of two subspecies: R.t.

Cellular mechanism underlying hydrogen sulfide induced mouse tracheal smooth muscle relaxation: role of BKCa.

Recent studies have suggested that hydrogen sulfide (H2S), an important endogenous signaling gaseous molecule, participates in relaxation of smooth muscle. Nevertheless, the mechanism of this relaxation effect on respiratory system is still unclear. The present study aims to investigate the physiological function as well as cellular mechanism of H2S in tracheal smooth muscle.

Risk factors associated with adverse drug events among older adults in emergency department.

Background: Little is known about the emergency department (ED) visits from drug-related injury among older adults in Taiwan. This study seeks to identify risk factors associated with adverse drug events (ADEs) leading to ED visits.

Methods: We prospectively conducted a case-control study of patients 65years and older presenting to the ED.

Involvement of CFTR in oviductal HCO3- secretion and its effect on soluble adenylate cyclase-dependent early embryo development.

Background: The cystic fibrosis transmembrane conductance regulator (CFTR) plays a critical role in electrolyte and fluid transport in epithelial cells, and women with cystic fibrosis (CF), caused by CFTR gene mutations, have a higher incidence of infertility.

Methods: In the present study, we investigated the expression of CFTR in porcine oviduct and its functional role in oviductal HCO(3)(-) secretion and embryo development with RT-PCR, western blot, patch-clamp, short-circuit current (I(sc)), pH measurement and embryo culture.

Results: RT-PCR and western blot analysis showed the expression of CFTR mRNA and protein in the oviduct with its localization demonstrated by immunohistochemistry.

Prenatal diagnosis of extrastructurally abnormal chromosomes: clinical experience and literature review.

Background: To evaluate the clinical association of extrastructurally abnormal chromosomes (ESACs) with pregnancy outcome based on the cytogenetic characteristics of the ESACs.

Methods: We retrospectively reviewed 12 ESAC cases identified from 12,991 cases who received genetic amniocentesis between January 1983 and March 2008. Prenatal ultrasound findings, characteristics of ESACs (karyotypes, special features, origin, inheritance) and pregnancy outcomes were recorded.

Differences in clinical profiles of patients with Protobothrops mucrosquamatus and Viridovipera stejnegeri envenoming in Taiwan.

Envenoming by Protobothrops mucrosquamatus and Viridovipera stejnegeri accounts for the majority of venomous snakebites in Taiwan. We conducted a retrospective study to systematically examine the clinical manifestations and responses to antivenom therapy after P. mucrosquamatus and V.

The cystic fibrosis transmembrane conductance regulator in reproductive health and disease.

The cystic fibrosis transmembrane conductance regulator (CFTR) is an anion channel regulated by cAMP-dependent phosphorylation, which is expressed in epithelial cells of a wide variety of tissues including the reproductive tracts. Mutations in the gene encoding CFTR cause cystic fibrosis, a common genetic disease in Caucasian populations with a multitude of clinical manifestations including infertility/subfertility in both sexes. However, the physiological role of CFTR in reproduction and its involvement in the pathogenesis of reproductive diseases remain largely unknown.

Stimulating effects of dopamine on chloride transport across the rat caudal epididymal epithelium in culture.

The present study investigated the effects of dopamine on chloride transport across cultured rat caudal epididymal epithelium. The results showed that dopamine induced a biphasic short-circuit current (Isc) in a concentration-dependent manner. The dopamine-induced response consisted of an initial rapid spike followed by a sustained phase.

Antivenom therapy for crotaline snakebites: has the poison control center provided effective guidelines?

Crotaline snakebites (Protobothrops mucrosquamatus and Trimeresurus stejnegeri) are a common medical emergency in Taiwan that can be effectively treated by a bivalent F(ab)2 antivenom. We investigated the differences in the clinical outcomes of patients who received different therapeutic regimens of antivenom in a medical center where clinical toxicologists followed the poison control center (PCC) guidelines (medical group) and surgeons did not (surgical group). The medical records of inpatients with crotaline snakebites between 1991 and 2005 were reviewed and information on demographics, treatments, adverse effects of antivenom, and complications was abstracted and analyzed.

Trimeresurus stejnegeri envenoming during pregnancy.

Snake envenoming in pregnancy may cause fetal death and maternal mortality or morbidity. However, little is known about the toxic effects and optimal management of snake envenoming because of the rarity of cases. We report three cases in Taiwan in the past 15 years of pregnant women who were treated successfully after being bitten by Trimeresurus stejnegeri with local envenoming.

Detection of chromosome aberrations in the second trimester using genetic amniocentesis: experience during 1995-2004.

Objective: To retrospectively investigate the 10-year experience of prenatal diagnosis of fetal chromosome aberrations by second-trimester amniocentesis.

Methods: Data were collected at Taichung Veterans General Hospital between 1995 and 2004 from cytogenetic analyses of cultured amniocytes from second-trimester amniocentesis. The main indications for amniocentesis included advanced maternal age, abnormal maternal serum screening results, and abnormal ultrasound findings.

Involvement of muscarinic acetylcholine receptors in chloride secretion by cultured rat epididymal epithelium.

The aim of our present study was to investigate the short-circuit current response to carbachol in cultured rat cauda epididymal epithelia and the signal transduction mechanisms involved. Carbachol added basolaterally induced a concentration-dependent increase in short-circuit current (Isc) across the epididymal epithelium consisting of a rapidly rising phase and a long term sustained response. The response was almost abolished by removing Cl(-) from the extracellular medium and blockable by pretreating the tissues with DPC, indicating a substantial contribution of Cl(-) secretion to the carbachol-induced response.
