Star anise extracts modulation of reproductive parameters, fertility potential and DNA fragmentation induced by growth promoter Equigan in rat testes

ABSTRACT Equigan is an anabolic steroid that has been developed for veterinary use and derived from endogenous sex hormone testosterone that plays a key role in the development of male reproductive tissue as well as in puberty and spermatogenesis. The current study is aimed to investigate the possible prophylactic effect of star anise extracts (SAE) on the toxicity of rat testes, sexual hormones alternations, sperm count, sperm abnormalities and testicular DNA damage by Equigan. Forty adult male rats were equally divided into four groups (1st Control group, 2nd SAE group, 3rd Equigan and 4th Equigan+SAE group). Food and fluid intakes, relative body weight, potassium, chloride, phosphorous, non-progressive and immotile sperms were significantly increased in Equigan group as compared to control group. In contrast; relative testes weight, sodium, magnesium, total calcium, testosterone, FSH, LH, PRL, sperm count, progressive motility, and viability showed a significant decrease in Equigan group as compared to control groups. The relative weight of epididymis, seminal vesicles, prostates and serum calcium ions didn't change significantly in different studied groups. Co-administration of SAE with Equigan improved the sexual toxicity, electrolyte alternations, sperm count, abnormalities and DNA damage induced by Equigan.

Analysis of the neurotoxin anisatin in star anise by LC-MS/MS.

The aim of this work was to develop an analytical method capable of determining the presence of anisatin in star anise. This neurotoxin may induce severe side effects such as epileptic convulsions. It is therefore of prime importance to have rapid and accurate analytical methods able to detect and quantify anisatin in samples that are purportedly edible star anise. The sample preparation combined an automated accelerated solvent extraction with a solid-supported liquid-liquid purification step on EXtrelut®. Samples were analysed on a porous graphitic carbon HPLC column and quantified by tandem mass spectrometry operating in the negative ionisation mode. The quantification range of anisatin was between 0.2 and 8 mg kg⁻¹. The applicability of this validated method was demonstrated by the analysis of several Illicium species and star anise samples purchased on the Swiss market. High levels of anisatin were measured in Illicium lanceolatum, I. majus and I. anisatum, which may cause health concerns if they are misidentified or mixed with edible Illicium verum.

Four types of traditional Chinese medicine inducing epileptic seizures.

Traditional Chinese medicine has been used to treat disease in China for more than five thousand years. Over the last few decades it has been used increasingly in other countries as well. As its use has spread, interest in the adverse effects of traditional Chinese medicine, including epilepsy and epileptic seizures, has grown. To date, four types of traditional Chinese medicine have been found to induce epileptic seizures. In this review we will summarize the current knowledge about possible epileptogenic mechanisms of nux vomica, illicium henryi, betelnut and mulberry drawing on botanical, phytochemical, toxicological and animal studies.

Intoxicación por anís estrellado en un lactante menor / Intoxication by star anise in an infant

El anís estrellado (Illicium verum), es utilizado como remedio casero para tratar problemas gastrointestinales en niños y existe el riesgo de reacciones tóxicas severas y potencialmente fatales con la ingesta de este producto. Se presenta el caso de un lactante de 9 meses que requirió internación en la Unidad de Terapia Intensiva, posterior a la ingesta de cerca de dos litros de infusión de anís estrellado. Presentó rechazo a alimentos, irritabilidad, dificultad respiratoria, respiración acidótica y crisis convulsiva tónico-clónica generalizada, hemorragia digestiva alta y oliguria. Se recomienda evitar el uso de infusiones de anís estrellado en lactantes, por el riesgo de complicaciones como las que presentó este paciente.

Neurotoxicities in infants seen with the consumption of star anise tea.

Chinese star anise (Illicium verum Hook f.) is a well-known spice used in many cultures. Many populations use it as a treatment for infant colic. Japanese star anise (Illicium anisatum L), however, has been documented to have both neurologic and gastrointestinal toxicities. Recently, concern has been raised regarding the adulteration of Chinese star anise with Japanese star anise. We report 7 cases of adverse neurologic reactions in infants seen with the home administration of star anise tea. In addition, we have found evidence that Chinese star anise has been contaminated with Japanese star anise. More strict federal regulation of the import of star anise into the United States is warranted. Star anise tea should no longer be administered to infants because of its potential danger in this population.
